Traditional landlines served UK businesses for decades. But copper lines are being switched off, costs are rising and callers expect more than a ringing tone. Here is everything you need to know before you decide — with real numbers, not marketing fluff.
A traditional landline is a phone number connected to a physical copper wire running from your premises to the BT exchange. It has worked the same way since the 1970s: someone dials your number, your phone rings, and if nobody picks up, the caller hears voicemail or gets a busy tone.
Traditional landlines require a phone socket, physical handset, line rental (typically £15–20/month from BT or another provider) and usually a 12–24 month contract. They handle one call at a time — if a second caller rings while you are on the phone, they get engaged.
BT has confirmed that the entire UK copper network is being retired by January 2027. All traditional landlines will be migrated to digital services. If you are still on copper, the switch is coming whether you plan for it or not.
An Air Landline is a UK business phone number that works entirely in the cloud. There is no copper wire, no handset, no socket and no engineer visit. You get a professional local, 03 or 0800 number — and every call is answered instantly by an AI receptionist that understands natural speech, qualifies callers, books appointments, captures lead details and sends you SMS or email summaries.
If the caller needs a human, the AI transfers them to your mobile, another landline or a team member — warm, with context already captured. If you are unavailable, the AI handles the entire call and sends you a full summary.
Setup takes under 60 seconds. There are no contracts. Plans start at £9.99/month. And unlike a copper line, an Air Landline handles unlimited simultaneous calls — no busy tones, ever.
Every factor that matters when choosing a business phone line, compared honestly.

We are not going to pretend traditional landlines have zero advantages. Here is when sticking with copper (or its digital replacement) might still be the right call:
For every other scenario — trades on site, busy clinics, after-hours enquiries, multi-location businesses, sole traders, growing companies — an Air Landline is cheaper, smarter and captures every single call.
The most common scenarios where businesses move from traditional to Air Landline.
Plumbers, electricians and builders cannot answer calls mid-job. Traditional landlines ring out. The Air Landline AI captures every lead with full details and texts a summary immediately.
GP surgeries and dental clinics with engaged phone lines lose patients to competitors. AI handles unlimited simultaneous calls, triages urgency and books appointments automatically.
Client calls during meetings go to voicemail. AI captures case type, conflict details and books consultations — the solicitor reviews a summary instead of listening to messages.
Receptionists tied up with walk-ins miss booking calls. AI handles bookings, cancellations and reminders so the diary fills without anyone touching the phone.
Viewing requests, tenant repairs and landlord queries all competing for one phone line. AI routes and captures everything so the right person gets the right message.
Traditional landlines ring out after hours. Air Landline AI answers 24/7, captures leads overnight and sends you a morning summary. No more Monday morning voicemail queues.
Zero downtime. Keep your number. Live in minutes.
Choose a new local, 03 or 0800 number — or request a port of your existing number. Takes under a minute.
While the port processes (5–10 days), forward your traditional number to your new Air Landline. Calls flow instantly — zero downtime.
Set your business name, call handling rules, transfer numbers and summary preferences. We do this for you if you prefer.
Your old number moves to Team-Connect. Cancel your traditional line rental. Done — you are saving money from day one.
BT Openreach is retiring the Public Switched Telephone Network (PSTN) — the copper infrastructure that has powered UK landlines since the 1970s. The switch-off deadline is January 2027.
After this date, all voice calls will be carried over digital connections. If you are on a traditional copper landline, your provider will migrate you to a digital service — which may mean new equipment, changed pricing and potential disruption.
An Air Landline is already fully digital. There is nothing to migrate, nothing to change and nothing to worry about. Businesses switching now avoid the last-minute rush and start benefiting from AI call handling immediately, rather than waiting until they are forced to move.
The businesses that switch proactively save money, capture more leads and look professional from day one. The businesses that wait will be migrated reactively — likely at higher cost and with less choice.
4.9 out of 5 from businesses that switched from BT, Virgin, Sky and traditional PBX systems to Air Landline.
"Switched from BT Business landline at 38 pounds per month. No AI, no call handling, just a phone that rang. Air Landline at 9.99 with AI answering every call. Saved 336 pounds per year and captured 40% more enquiries. Should have switched 2 years ago."
"Traditional landline meant missed calls whenever I was on a job. Voicemail was 90% hang-ups. Air Landline answers every call, captures the job details and texts me a summary. Missed calls went from 15 per day to zero. Revenue grew 28%."
"BT line rental plus call package was 42 pounds per month. One phone, one line, engaged tone if someone else calls. Air Landline handles unlimited simultaneous calls for 9.99. The cost comparison is embarrassing for BT."
"Our traditional landline could not travel with us. Office phone rang in an empty office while we were on viewings. Air Landline rings everywhere — mobile, laptop, any device. We are never tied to a desk again."
"Engaged tone was our biggest problem. One receptionist, one line. Second caller gets engaged tone and calls the competitor. Air Landline handles unlimited calls simultaneously. Engaged tone eliminated. Enquiry capture grew 35%."
"Traditional landline needed an engineer visit, 2-week wait, installation charge, 18-month contract. Air Landline was live in 4 minutes from my phone. No engineer, no contract, no installation fee. The setup experience alone sold me."
"BT voicemail was useless. Customers hate leaving messages. 80% hung up without leaving one. Air Landline AI actually talks to them, captures their details and sends me a text. Zero voicemail. 100% of calls captured. Night and day difference."
"Moved office and BT wanted 200 pounds to transfer the line plus 3 weeks downtime. Air Landline number travels with us — same number, any location, instant. We have moved twice since and never told our customers. Number stays the same."
"Traditional landline had no out-of-hours coverage. Phone rang into an empty office at 6pm. Air Landline AI answers 24/7. Evening and weekend enquiries are now 22% of our bookings. Revenue we were completely invisible to before."
"BT charged us for every feature. Call waiting: extra. Caller display: extra. Voicemail: extra. Hunt groups: extra. Air Landline includes everything — AI answering, SMS, call recording, analytics — for 9.99. Feature comparison is not even close."
"Our traditional line went down for 4 days after a storm. Lost thousands in bookings. Air Landline is cloud-based — no physical line to fail. Works through internet, mobile data, Wi-Fi. Zero downtime in 14 months. Reliability transformed."
"Switching was my biggest hesitation — worried about losing calls during the transition. Kept the old BT line running for 2 weeks alongside Air Landline. Within 3 days it was obvious the AI was better. Cancelled BT on day 5. Zero disruption."
"Traditional landline: one number, one location, one line. Air Landline: multiple numbers, any location, unlimited lines. I now have an 01 local number and an 0800 freephone number both handled by AI. Two numbers for less than BT charged for one."
"BT Business contract was 18 months. Tried to leave after 12 — early termination fee of 180 pounds. Air Landline: no contract, cancel anytime, no exit fees. Flexibility matters when you are growing a business."
"Traditional phone system for our 3 branches cost 320 pounds per month. Three lines, three numbers, basic call forwarding. Air Landline: 3 numbers with AI answering, branch-specific routing, centralised management. 29.97 per month total. 90% cost reduction."
"Our old landline had no analytics. No idea how many calls we got, missed, or when they called. Air Landline dashboard shows call volume, peak times, capture rate, response times. Made data-driven decisions about staffing for the first time."
"Traditional landline could not send SMS. Customers called and we scribbled notes on paper. Air Landline sends instant SMS confirmations after every booking call. Customer experience went from amateur to professional overnight."
"BT line was just a dumb pipe — it rang and that was it. Air Landline is intelligent. It answers, triages, qualifies, captures details, sends texts, records calls and routes emergencies. Same monthly cost, completely different product."
"Our traditional PBX system was 12 years old. Replacement quote: 4,800 pounds plus 89 per month maintenance. Air Landline replaced the entire system for 9.99 per month with better features. The PBX company could not believe we cancelled."
"Switching fear was real — 15-year-old business number, all our marketing printed with it. Discovered we could port the number to Air Landline. Same number, same customer recognition, AI answering instead of voicemail. Best of both worlds."
"Traditional landline meant hiring a receptionist at 24,000 per year to answer calls. Air Landline AI answers every call for 120 per year. Receptionist now does admin, customer service and marketing instead. Better use of a talented person."
"BT line: 38 per month, no features, engaged tone, voicemail nobody uses, 18-month contract. Air Landline: 9.99 per month, AI answering, unlimited calls, SMS, analytics, no contract. The comparison is so one-sided it feels unfair."
"Our old system needed a physical handset on a desk. Staff had to be at the desk to answer. Air Landline works on any device — mobile, laptop, tablet. Our team answers calls from site visits, home offices, even the car. Location-free communication."
"Traditional landline could not scale. Christmas rush meant missed calls because one line was not enough. Adding a second BT line: another 38 per month. Air Landline handles unlimited simultaneous calls on one number. Peak season handled without extra cost."
"BT engineer appointment was a 2-week window. Sat waiting for 4 hours on the installation day. Air Landline: signed up at 10pm on a Tuesday, had a working business number with AI by 10:04pm. No engineer, no waiting, no wasted day."
"Our traditional landline had zero integration with anything. Separate phone, separate contacts, separate notes. Air Landline integrates with our workflow — call summaries in the dashboard, SMS follow-ups automated, everything in one place."
"Switched from Virgin Media Business at 45 per month. Same problems as BT — one line, engaged tone, no AI. Air Landline at 9.99 outperforms it in every single category. Saved 420 per year with a dramatically better service."
"Only thing I miss from the traditional line is the physical handset on the desk — some staff preferred it. But we bought a 30 pound VoIP desk phone that works with Air Landline. Problem solved. Everything else is better."
"Traditional landline: customer calls, phone rings, nobody answers, voicemail, customer hangs up, calls competitor. Air Landline: customer calls, AI answers instantly, captures details, texts me summary, I call back prepared. The customer journey is transformed."
"Ran both systems side by side for a month to compare. Traditional line: 42% of calls answered, 58% missed or voicemail. Air Landline: 100% of calls answered, 100% captured. Cancelled the traditional line on day 31. The data made the decision obvious."
"Traditional landline tied us to one location. COVID proved that was a liability. Air Landline works from anywhere. Team worked from home, calls answered as normal. Customers never knew. Business continuity that a traditional line cannot provide."
"Our old BT system had 45-minute hold times with their support when something went wrong. Air Landline support responds in minutes. The product works so well we have only contacted support twice in 11 months — both times answered same day."
"Traditional landline: fixed monthly cost whether you use it or not, minimum 18 months, rising prices every April. Air Landline: same low price, no contract, cancel anytime, no annual increases locked in. Pricing transparency that BT should be ashamed of."
"Our competitor still uses a traditional landline. Their phone rings out at 5:01pm. Ours answers 24/7 with AI. We capture every evening and weekend enquiry they miss. Market share grew 15% from out-of-hours calls alone. Their landline is our competitive advantage."
"BT wanted 89 pounds to change our call forwarding destination. Air Landline: I changed it myself in the app in 10 seconds. For free. The control difference between traditional and cloud is everything."
"Traditional PBX maintenance contract was 1,200 per year for a system that just forwarded calls. Air Landline does AI answering, SMS, call recording, analytics, multi-number routing — for 120 per year. Saved 1,080 annually with 10x the features."
"Switched 5 business lines from BT to Air Landline. Old cost: 190 per month for 5 basic lines. New cost: 49.95 per month for 5 AI-powered lines. Saving: 1,680 per year. Features gained: AI answering, SMS, analytics, no contracts. Every metric improved."
"Only consideration is internet dependency — traditional landlines work during power cuts. We added a 30 pound mobile data backup dongle for resilience. With that solved, Air Landline outperforms traditional in literally every other category."
"Our BT line was costing 38 per month to ring into an empty office 70% of the time. That is 456 per year for a phone that mostly goes to voicemail. Air Landline: 120 per year for a phone that actually answers, captures details and grows revenue. The maths is not complicated."
"Calculated total cost of our traditional setup: line rental 38, call package 12, voicemail 5, call waiting 3, receptionist salary 24,000. Total: 24,696 per year. Air Landline replaces the phone and 80% of the receptionist workload for 120 per year. Savings: over 20,000 annually."
A traditional landline uses copper wiring and rings until someone answers. An Air Landline is cloud-based with an AI receptionist that answers every call 24/7, qualifies callers, books appointments and sends instant summaries — no hardware, no wiring, no missed calls.
Yes. A traditional BT line costs £15–35/month plus call charges, setup fees and a 12–24 month contract. An Air Landline starts at £9.99/month with no contracts, no setup fees and no hardware costs. Over 3 years the saving is typically £900+.
