AI phone answering for UK trades & service firms
When you're on a job, Belgrave Line answers your phone in your firm's name, takes the customer's name, number, address and problem, and texts it to you within a minute. You ring back the jobs you want. The customer doesn't ring the next firm on Google.
Pretend you've got a leak. Our demo firm, "Hartley Plumbing", answers. It takes 60 seconds.
Example only. Made-up customers.
Try it before you decide

Our demo firm, "Hartley Plumbing", answers. Describe a job, give a made-up address, and hang up. It takes about 60 seconds.
Normal UK call rates. Calls to the demo line are recorded so we can improve it.
Use your computer's microphone instead of your phone. Your browser will ask for permission first.
Tell me your firm's name and what you do. I'll set up a demo that answers as you, then we'll ring it together.
Example written to show the flow, not a real customer call. It never quotes prices or promises a time: you decide that when you ring back.
The problem
You can't answer with your hands full. But the customer with a leak won't wait, and by the time you ring back, someone else has the job.
The phone buzzes in your pocket. By the time you're down, they've hung up.
"Sorry mate, we've already got someone coming." The job's gone, and so is the next one they'd have sent you.
Listening to voicemails, texting people back, working out who wanted what, instead of switching off.
The fix
Keep your own number. You answer as normal. Only the calls you miss come to us.
Busy, on a job or after hours, your phone forwards the call to Belgrave Line. When you're free, you pick up as normal.
"Good morning, Smith Plumbing & Heating." It says it's your assistant, asks the right questions, and checks the address and postcode.
Name, number, address, the problem and how urgent it is. Emergencies are flagged. You ring back the jobs you want.
What changes
Who it's for
If customers ring you and you can't always pick up, it works the same way. We set the questions to suit your work.
Leaks, no heating, boiler services. Emergencies flagged urgent.
Faults, tripping circuits, EV chargers, rewires. Safety questions asked first.
Quotes, surveys and storm damage. Takes the address so you can plan a visit.
Lock-outs and call-outs where the first firm to answer gets the job.
Booking requests and quotes taken while you're working.
Not on the list? Book a demo and I'll set one up as your business.

Questions tradespeople ask
Yes. It answers in your firm's name, says it's an AI assistant and that calls may be recorded. It takes their details so you can ring back the jobs you want.
On Pro and Team, putting urgent calls straight through to a number you choose is on the way, included when it launches. Today, on every plan, it takes the details and texts you within a minute, with emergencies marked URGENT.
It doesn't guess. It says you'll call back, takes their details and the question, and puts the question in your text.
Yes, if your phone can forward calls when you're busy or don't answer, which almost every UK mobile and landline can. We set up the forwarding with you. Nothing to install.
Yes, if customers ring you and you can't always pick up. We set the questions to suit your business. Book a demo and I'll set one up as your firm.
No. You keep your number. Your phone forwards calls to Belgrave Line only when you're busy, don't answer, or it's after hours. It takes two minutes and we do it with you.
It asks the right questions (water leaking? no heating? stopcock off?) and marks the text URGENT so it stands out. It never promises an arrival time you haven't agreed.
It only takes details and answers the questions you've approved. You get the full summary every time. I review your calls in the first month and fine-tune it.
We recommend Pro for most firms: more calls, faster setup, and, when they launch, a weekly view of every call and urgent calls put straight through to you. Solo suits a sole trader who mostly needs a text of each missed call. Team is for firms with a few engineers or an office. You can switch plans any time with a text.
About 50 a month on Solo, 120 on Pro and 250 on Team. Spam, sales calls and wrong numbers never count. Going over now and then is fine; if you regularly do, we'll talk before anything changes.
Yes. Press "Start now", pay by card, fill in the 2-minute setup form, and your line is ready within 48 hours. I text you when it's live. You can text me any time if you'd rather talk.
Text me in your first 30 days and I'll refund your first payment in full. No forms, no questions. After that, cancel any time with one text.
Usually not. Most UK mobile plans include diverted calls in your minutes. Some landlines and business lines charge for each diverted call, so check your tariff. We set the forwarding up with you and test it before you go live.
Text or email me and I'll cancel it the same day. You won't be charged again. In your first 30 days you also get your first payment back in full.
No. Monthly or yearly, and you can cancel any time with a text. The founding price is locked for as long as you stay.
Call details are stored securely and used only to pass enquiries to you. You stay in control of your customers' data, and we sign a data processing agreement with every client. See our privacy notice.
Hear it answer as your firm in 2 minutes, then start today. Set up for you, no contract, and a full refund if you're not happy in the first 30 days.
