A homeowner calls about a rear extension. You are knee-deep in a foundation pour with concrete arriving in 20 minutes. You cannot stop. They call the next builder on Checkatrade. That is a £40,000–£80,000 contract you just lost because your boots were in wet cement. An Air Landline qualifies every lead while you build.
Building is the highest-value trade by contract size. A single rear extension is £30,000–£80,000. A loft conversion is £25,000–£60,000. A full house renovation can be £100,000+. These are life-changing contracts — and they are lost to voicemail because you are on site with a mixer running and a crew to manage.
An Air Landline answers every call, qualifies the project (scope, budget, timeline, planning), requests photos and plans, checks your area and sends you a quote-ready lead summary. You arrive at the site visit already knowing the project. The homeowner is impressed. The contract is yours.
See how the AI captures scope, budget and timeline — in under 60 seconds.
Different projects need different qualification. The AI adapts its questions to the project type.
AI asks: single or double storey? Rear, side or wrap-around? Planning permission status? Architect appointed? Structural engineer involved? Party wall agreements needed? Budget range and timeline. Your biggest-ticket residential work — fully qualified on the first call.
AI asks: hip-to-gable, dormer, mansard or Velux? Current loft usage? Head height if known? Staircase location preference? Bathroom included? Planning required (dormer) or permitted development (Velux)? One of the most searched-for building projects online.
AI asks: layout change or like-for-like? Structural walls involved? Kitchen units chosen or needing advice? Bathroom suite selected? Underfloor heating? Tiling included? Budget range. Photos requested — you quote with the existing layout in hand.
AI asks: integral or detached? Purpose (bedroom, office, playroom, gym)? Heating and plumbing needed? Planning or building regs route? Current garage condition? Growing demand since WFH — high conversion rate from enquiry to contract.
AI asks: plot secured? Planning granted? Architect drawings available? Number of bedrooms and floors? Approximate build area in sqm? Project managed or need full service? Budget including contingency? Your highest-value leads — £150,000–£500,000+ per project.
AI asks: hard or soft landscaping? Driveway material preference (block paving, resin, tarmac, gravel)? Approximate area? Drainage concerns? Retaining walls? Garden rooms or structures? Photos requested — you measure from the image before the site visit.
AI asks: what damage — cracking, subsidence, lintel failure, damp? How long has it been happening? Structural survey done? Insurance claim in progress? Urgent or monitoring? Photos requested showing the crack, damp or damage with a ruler for scale.
AI asks: shop, office, restaurant or industrial? Approximate area in sqft? Fit-out specification level? Landlord approvals in place? Main contractor or direct client? Timeline and budget. Purchase order or corporate invoicing needed? Routes to your commercial estimator.
Building leads need deeper qualification than any other trade. The AI captures consistently on every call:
Builders waste more time on unqualified leads than any other trade. A 45-minute site visit to discover the customer has a £5,000 budget for a £40,000 extension is a morning lost. The AI pre-qualifies:
Your estimator only sees qualified, realistic, in-area leads with full project details. Quote conversion goes up because you are quoting the right jobs.
When you arrive at the site visit, you already know the project type, approximate scope, budget range, planning status, whether drawings exist and you have seen photos. The homeowner says: "Wow, you already know what we're after." That preparation wins contracts. Builders who arrive cold, ask "so what are you thinking?", and take notes on the back of an envelope lose to the builder who arrived prepared.
From homeowner call to qualified lead with photos — while you are on site.
7:30pm Wednesday. You finished on site at 5. AI answers: "Good evening, thank you for calling Hartley Building, how can I help?"
"We want a single-storey rear extension." AI: "Lovely. Can I ask a few questions so we can prepare an accurate quote?"
Single storey rear, kitchen-diner, approximately 4m × 6m. Bi-fold doors. Planning granted. Architect drawings ready. Semi-detached. SK10 postcode. Budget £40,000–£50,000. Want to start April.
AI: "That sounds like a great project. Can I arrange for you to send us some photos?" SMS sent: "Please send photos of the rear of the property and your drawings."
"We'd love to come and have a look. We have availability next Tuesday morning — would that work?" Homeowner: "Perfect." Site visit booked.
Next morning: qualified lead, SK10, rear extension 4×6m, planning granted, drawings ready, budget £40–50k, start April, site visit Tuesday. Photos of the property already in your inbox. £45,000 contract waiting.
On site all day, missing 8+ calls per week. AI captures every lead with project type, budget and planning status. Won 2 extension contracts in the first month worth £85,000 combined — from leads competitors missed. Quote conversion up because he arrives at site visits prepared.
Office admin spending 3 hours per day qualifying leads and routing to the right team (extensions, refurbs, landscaping). AI handles the entire qualification process. Misrouted leads dropped to zero. Estimator time on unqualified site visits cut 60%. Revenue per estimator up 25%.
Loft conversions need specific qualification — type, head height, staircase, planning. AI asks the right questions every time. Leads arrive with dormer vs Velux, planning status and budget. Quote accuracy up 35% because the estimator knows the scope before visiting.
Evening calls are the highest-value leads — homeowners who have done their research and are ready to commit. AI captures every evening enquiry with full 10-point qualification. Won 3 extension contracts from evening calls in the first quarter. Total value: £180,000.
Refurb enquiries need photos to quote accurately. AI requests photos on every call. 75% of customers send photos within an hour. Estimator quotes from the photos — 30% of refurbs quoted without a site visit. Speed of response doubled. Win rate up because first accurate quote wins.
Commercial leads need project scope, floor area, specification level, contractor contact and invoicing details. AI captures everything on the first call. Estimator receives a quote-ready package. Commercial contract pipeline grew 40% from properly captured leads.
Most builders arrive at a site visit cold. "So, what are you thinking?" They take notes. Ask basic questions the homeowner already answered on the phone. Measure up. Go away and spend 3 hours preparing a quote they could have started on the drive over.
With AI, you arrive already knowing:
You walk in and say: "I've seen your drawings and photos — the 4×6 rear extension with the bi-folds is a great project. Based on what I've seen, I think we're looking at the £42,000–£48,000 range depending on your kitchen specification. Let me take some measurements and I'll have a detailed quote to you by Friday."
The homeowner is impressed. You are professional, prepared and specific. Builder B arrives next week, says "so what are you after?", takes 45 minutes measuring and promises a quote "in a couple of weeks." You have already won.
Building work sits at the intersection of customer ambition and regulatory reality. A homeowner calls wanting a double-storey extension. Do they have planning permission? Have they spoken to building control? Is there a party wall issue? Most builders discover the answers to these questions at the site visit — 45 minutes into a visit that could have been a 2-minute phone qualification.
On every project enquiry, the AI asks about planning status and categorises it:
The AI understands that most building work requires building regulations approval even when planning permission is not needed. For extensions, loft conversions, structural alterations, electrical work and plumbing changes, it captures whether building control has been notified and whether the customer has appointed a building control body (local authority or approved inspector). This information goes into your lead summary so your estimator includes building control fees in the quote.
Storm damage, subsidence, flood repair and fire reinstatement are high-value, time-sensitive projects. The AI captures:
Insurance restoration work is typically £15,000–£80,000 per project with reliable payment. The AI ensures every detail is captured on the first call so you can respond to the loss adjuster with a professional, detailed assessment within hours — not days.
Building projects involve multiple trades — groundworkers, bricklayers, roofers, electricians, plumbers, plasterers, joiners, decorators. As the main contractor, you are the single point of contact for the customer and every subcontractor. That means your phone never stops. And when it goes to voicemail, the project stalls.
The Air Landline separates customer calls from subcontractor calls and handles each appropriately:
A typical extension generates 40–60 phone calls over the 10–16 week build. Without AI, every one of those calls interrupts you on site. With AI, only genuine emergencies reach your mobile. Everything else is captured, categorised and waiting in your dashboard when you check it at lunch or end of day.
The result: your site work is uninterrupted, your communication is documented, and your customer thinks you are the most organised builder they have ever hired. That reputation wins referrals. And referrals are the highest-converting leads in construction — because the homeowner already trusts you before you arrive.
Real UK builders using AI to qualify every lead, win more contracts, and never miss an enquiry.
"The AI captured a rear extension enquiry while I was pouring foundations. Full details — 4x6m kitchen-diner, planning granted, drawings ready, budget £45k. I called them back at lunch and booked the site visit. That's a £47,000 contract from a call I never answered."
"Evening calls are our best leads and we were missing all of them. The AI now captures every one with full 10-point qualification. Won three loft conversions from evening enquiries in the first quarter — total value £135,000."
"As a sole trader I was wasting half my Saturdays on site visits for jobs that were never going to work — wrong budget, no planning, out of area. The AI pre-qualifies everything now. Every site visit I do converts because I'm only visiting the right leads."
"Kitchen and bathroom refurbs need photos to quote properly. The AI requests photos on every call and 75% of customers send them within an hour. I've quoted 30% of refurbs without a site visit. Speed of response doubled. Win rate is way up."
"We run three teams — extensions, refurbs, and landscaping. The AI routes leads to the right team automatically. No more extensions going to the landscaping crew or patio jobs going to the structural team. Pipeline is properly organised for the first time."
"The budget capture alone is worth the subscription. I was doing site visits for people with £8,000 budgets wanting £40,000 extensions. Now the AI flags unrealistic budgets and I only visit customers who can actually afford the work."
"Garage conversions are brilliant margin work and the enquiries come from people who've been thinking about it for months. The AI captures the garage type, intended use, and whether they need planning. I arrive at the site visit already knowing the conversion inside out."
"Commercial fit-out leads need project scope, floor area, specification level, and contractor details. The AI captures it all on the first call. My estimator gets a quote-ready package instead of a scribbled message. Commercial pipeline grew 40% in three months."
"The planning status question is genius. I used to drive 40 minutes to a site visit only to discover they hadn't even applied for planning. Now the AI captures it on the first call and I know if it's a ready-to-start job or a 6-month pipeline lead."
"Driveway and landscaping enquiries are bread and butter between big jobs. The AI captures material preference, area size, drainage concerns, and sends a photo request. I can quote most driveways from the photos alone. Quick turnaround wins these jobs."
"I switched from a virtual receptionist that cost £200 a month and just took names and numbers. Air Landline costs a fraction and captures the full project scope, budget, planning status, and photos. No comparison whatsoever."
"Structural repair work comes in bursts after storms. Three calls in one afternoon about subsidence, cracked walls, and water damage. The AI captured all three with photos, insurance details, and urgency levels. I prioritised the right one and quoted all three that evening."
"I put the landline on my van, Checkatrade listing, and Google Business. Call volume went up 35% in the first month. People trust a proper business number. The AI handles the overflow when I'm on site. Not a single lead lost."
"New build enquiries are worth £150k+ each. Missing even one is catastrophic. The AI captures plot details, planning status, architect involvement, build specification, and budget. I follow up within hours. Three new build contracts this year from AI-captured leads."
"The SMS photo request after each call is the feature I didn't know I needed. Customers send photos of the property, existing layout, damage, or drawings. I've quoted jobs from the van at lunchtime without ever visiting the site. Turnaround is everything."
"Insurance restoration work is our highest-margin service. The AI captures the damage type, insurance company, claim reference, and loss adjuster details on the first call. We respond to the loss adjuster within hours. Speed of response wins these contracts every time."
"Our estimator was spending 3 hours a day on the phone qualifying leads. Now the AI does it on every call. He spends that time preparing accurate quotes instead. Quote turnaround dropped from 2 weeks to 3 days. That speed wins contracts."
"Hip-to-gable loft conversions are our speciality. The AI asks about roof type, head height, staircase location, and planning — exactly what I need to know. Leads arrive pre-qualified with the right conversion type identified. No more wasted visits discovering it's a Velux-only roof."
"The dashboard analytics showed me that 60% of my enquiries come between 6pm and 9pm. Before Air Landline those all went to voicemail. Now every single one is captured with full project details. That evening window is worth over £200,000 a year in contract value."
"Party wall issues used to catch me off guard at site visits. Now the AI asks about attached neighbours and whether party wall agreements are in place. I arrive knowing the full picture. Customers see me as thorough and professional from the start."
"Started my building business 18 months ago. The Air Landline made me look like an established contractor from day one. Customers on Checkatrade said I sounded more professional than firms with 20 years' experience. That perception wins work."
"Existing clients calling about snagging or follow-up work used to interrupt my site day constantly. Now the AI captures their query and I deal with it end of day. Site productivity is up because I'm not stopping every 20 minutes to answer the phone."
"We do property renovations — full gut and refurb. The AI captures property size, scope of work, current condition, budget range, and timeline. These are £80k–£150k projects. One captured lead pays for a decade of the service."
"The spam filtering is underrated. I was getting 6-8 cold calls a day about scaffolding hire, insurance, and SEO. Now the AI blocks them before they reach me. My phone only rings with real customers and genuine subcontractor updates."
"Subcontractor coordination is a nightmare on big jobs. The AI now captures messages from my electrician, plumber, and roofer — availability changes, delivery updates, schedule shifts. Everything logged against the project. My site diary writes itself."
"Side return extensions in London are competitive. The AI captures the exact project — width, length, planning status, party wall, budget. I quote within 48 hours while competitors take 2 weeks. Speed and preparation win every time."
"Garden room and summer house builds are a growing market. The AI captures size, intended use, whether they need electrics and plumbing, and whether planning is needed for the size. Quick-turnaround work that fills gaps between big projects."
"Honestly the best investment in my building business this year. The AI handled 93 calls last month — 41 qualified leads with full project details, 22 with photos attached. My estimator had a full pipeline without making a single outbound call."
"Damp and timber treatment enquiries need specific info — where's the damp, how long, survey done, insurance claim. The AI captures it all including photos of the affected areas. I can triage whether it needs a survey or if I can diagnose from photos."
"From £9.99 a month I get a 24/7 lead qualification system that captures project scope, budget, planning, photos, and sends me a quote-ready summary. My last extension contract was £62,000. The maths speaks for itself."
"Garage conversion enquiry at 9pm on a Tuesday. Homeowner wanted a home office. AI captured dimensions, current use, planning status, budget £18k. I called Wednesday morning. Site visit Thursday. Contract signed Friday. £19,500."
"Insurance restoration work — fire damage to a semi. Loss adjuster needed a builder fast. AI captured claim reference, insurance company, damage extent, access details. I responded same day. £67,000 contract. Reliable payment from the insurer."
"Checkatrade generates 15 leads a month for us. Before AI, we answered maybe 8. Now every single one is captured with full project details. Checkatrade ROI doubled because we stopped wasting the leads we were paying for."
"Two-storey extension enquiry. AI captured everything — 6x4m ground floor, 4x4m first floor, current layout, planning applied, architect on board, budget £85k. My estimator started the quote before I even called them back. Won a £92,000 contract."
"Sunday morning call. Couple found us on Google. Wanted a complete house renovation — rewire, replumb, new kitchen, 2 bathrooms, extension. AI captured the full scope. £145,000 project. Would have been voicemail on a Sunday."
"Commercial fit-out enquiry from a restaurant wanting a full refit. AI captured the scope — kitchen extraction, new toilets, bar installation, timeline 6 weeks. £38,000 commercial contract from a call that came in while I was on another site."
"Time-waster filtering is worth the subscription alone. 3 calls last week with £5k budgets wanting full extensions. AI flagged them. I didn't waste 3 Saturday mornings on site visits that were never going to convert."
"Structural repair enquiry — subsidence on a Victorian terrace. AI captured crack locations, when noticed, whether insurance involved, structural engineer report status. I arrived at the site visit already knowing what I was dealing with."
"My wife used to answer the phone for me. She's not a builder — couldn't ask the right questions. AI asks about planning, budget, access, timelines. The leads I get now are 10x more useful than 'someone called about some building work.'"
"Landscaping and driveway enquiries capture the area, current surface, drainage issues, vehicle access and budget. Photos requested. I quote 40% of driveways from photos alone. Speed wins the job every time."

Voicemail loses 90% of callers. Answering on site is noisy, rushed and dangerous. A partner takes messages but can't qualify projects. The AI captures, qualifies, photographs and delivers quote-ready leads — 24/7.
You are the builder, the estimator, the project manager and the phone operator. You physically cannot answer calls while working on site. AI becomes your office team — qualifying every lead, requesting photos, checking your area and delivering quote-ready summaries. Customers think you have staff. You have an AI that costs less than one hour's labour.
3–10 vans, specialist teams for extensions, refurbs and landscaping. AI routes enquiries to the correct team automatically. The office sees all leads across all teams. Pipeline visibility, consistent qualification and zero missed leads — regardless of which team is on which site.
High-value contracts (£25,000–£100,000+) that require detailed qualification — scope, planning status, architect involvement, budget, access. AI captures every detail on the first call so your estimator starts the quote with 80% of the information. Quote turnaround drops from 2 weeks to 3 days. Speed wins contracts.
Refurb projects that benefit enormously from photos before the site visit. AI requests photos on every call — 75% of customers send within an hour. You quote 30% of refurbs without a site visit. Faster quotes, higher win rates, fewer wasted trips.
Commercial fit-outs, insurance restoration, fire reinstatement — high-value contracts with specific capture requirements. AI captures claim references, loss adjuster details, insurance company names, damage type and urgency. You respond to loss adjusters faster than competitors. Insurance work: £15,000–£80,000 with reliable payment.
Yes. 10-point qualification: project type, scope with type-specific follow-ups, budget range, timeline, planning status, architect/drawings, property type, access, postcode and photo request. You receive a quote-ready lead, not a vague voicemail.
Yes. Budget captured on every call. Unrealistic budgets flagged. Out-of-area handled politely. Planning not started logged as future lead. Wrong trade redirected. Your estimator only sees qualified, realistic, in-area leads.
Yes. Extensions (single/double, rear/side), loft conversions (dormer/Velux/hip-to-gable), kitchen and bathroom refurbs, garage conversions, new builds, landscaping, structural repairs and commercial fit-outs — each with project-specific follow-up questions.
Yes. SMS sent after every call. 75% of customers send photos within an hour. You see the property, existing layout and any drawings before the site visit. Some refurbs can be quoted from photos alone.
Yes. Configure each team's specialism — extensions, refurbs, landscaping, commercial. AI routes to the right team. Office sees all leads. Project value, area and timeline captured consistently for pipeline management.
65% of building enquiries come evenings and weekends. AI answers 24/7 with full 10-point qualification. These are your highest-value leads — homeowners who have researched, compared and are ready to commit. First to respond wins the site visit.
Indirectly, yes. By capturing photos, plans, scope, budget and planning status on the first call, your estimator starts the quote with 80% of the information already in hand. Quote turnaround drops from 2 weeks to 3 days. Speed wins contracts.
From £9.99/month. One missed extension is £30,000–80,000. One missed loft conversion is £25,000–60,000. One captured lead that converts pays for a lifetime of the service. The ROI is not a calculation — it is obvious.
Yes. The AI asks about planning status on every call — granted, applied, not yet applied, permitted development, or unsure. For projects requiring building regulations sign-off, it captures whether building control has been notified. Customers who need guidance on planning are advised to consult their local authority, and the query is flagged in your lead summary so you can discuss it at the site visit. This pre-qualification saves you from wasted visits to projects that are months away from starting.
Yes. Storm damage, subsidence, flood repair and fire reinstatement are high-value, time-sensitive projects. The AI captures the damage type, insurance company name, claim reference number, whether a loss adjuster is involved, and urgency level. Photos of the damage are requested by SMS. Warranty callback work is logged with the original job reference. Insurance restoration projects are typically £15,000–£80,000 with reliable payment — the AI ensures you capture every detail to respond to loss adjusters quickly.
An office administrator costs £12–15 per hour, works limited hours, takes holidays, and may not understand the difference between a dormer and a hip-to-gable loft conversion. Air Landline costs from £9.99 per month, works 24/7/365, qualifies every project type with the right follow-up questions, captures photos and plans, checks postcodes against your coverage area, and never puts a caller on hold. It also works evenings and weekends — when 65% of your highest-value leads actually call.
Yes. Your Air Landline number receives both calls and SMS. Customers can text photos of the property, existing layout, architect drawings, structural survey reports, or damage directly to your business number. The AI also sends SMS photo requests after every call. All texts appear in your dashboard alongside call history so your estimator has everything in one place for quoting — photos, plans, project scope, budget, and planning status.
AI qualifies every lead with scope, budget, planning and photos — so you arrive prepared, quote fast and win the work. Every £40,000 extension captured. Every time-waster filtered.
