For heating engineers
Never miss a boiler breakdown again.
When the first cold snap hits, every heating engineer's phone rings at once — and you can only be on one boiler. Graftline answers the rest, sorts the no-heat emergencies from the service bookings, and puts every job on your WhatsApp.

Who's ringing while you can't answer
Heating work is seasonal, urgent, and safety-critical — three reasons a missed call costs more in this trade than almost any other.
No heating, no hot water, January
A family with young kids and a dead boiler doesn't leave a voicemail — they ring the next Gas Safe engineer on the list. In a cold snap the calls stack up faster than you can physically answer, and every rung-out call is work you did the marketing to earn.
The landlord's CP12 batch
Letting agents book gas safety certificates in batches. They ring, they need dates, and they go with whoever picks up and sounds organised. It's the routine work that keeps a winter diary full — and it's lost silently.
The gas smell call
The one call where the right answer isn't “we'll book you in.” Any mention of a gas smell and Graftline reads out the National Gas Emergency line — 0800 111 999 — before anything else, on every call, hard-coded. No judgement calls, no exceptions.
The new boiler enquiry
Two to four and a half grand of work that rings once, mid-morning, while you're mid-service. These callers are collecting quotes — being unreachable just means being off the list.
What one unanswered call can be worth
Graftline costs £79.99 a month. Look at what a single heating engineer job typically goes for, and the sums do themselves — one saved call usually covers the month.
Typical UK price ranges, shown to illustrate what a missed call can cost — not a promise of work. Your prices are your own, and Graftline only ever quotes what you tell it to.
How Graftline works
Never miss the job. Skip the retyping.
Graftline answers the call you miss, gets the job onto your phone and reuses those details when you're ready to invoice. You stay in control from first ring to final send.
Around 10 minutes to get your missed calls covered.

Answers when your hands are full
Two rings, your business name. It asks what the boiler's doing — or not doing — whether there's an error code on the display, whether there's any heating or hot water at all, and who's in the house. Then postcode and callback number.

Gas safety first, always
A mention of a gas smell gets the caller the National Gas Emergency line (0800 111 999) before anything else — hard-coded on every call. A genuine no-heat emergency gets flagged urgent and you're alerted straight away.

Straight answers, no small print.
How does it handle a gas smell?
The caller hears the National Gas Emergency line — 0800 111 999 — read out first, before anything else. It's hard-coded into every call and it's the one behaviour we don't let anyone change. After that, the details still come through to you.
Winter is chaos. Can it keep up?
That's exactly when it earns its keep. You physically can't answer three calls while repairing a boiler — Graftline picks up whatever you can't, so a cold-snap surge turns into a WhatsApp list of jobs instead of a missed-call log. Your plan includes 180 answered minutes a month, and top-ups are opt-in only — we never auto-charge you.
Can it book in services and CP12s?
Yes. Routine work is where it's smoothest — it quotes your starting prices as "from £…", takes the property details and the tenant's contact if it's a landlord job, and the booking lands on your WhatsApp and dashboard.
Does it actually know anything about boilers?
It's briefed on your services and asks sensible questions — what the boiler's doing, any error code, whether there's hot water — but it doesn't diagnose and it never tells callers to start pressing buttons. It gets you the details; you make the engineering calls.
Do I need a new phone number?
No. Keep the number on your van and your Gas Safe listing, and set your phone to divert to Graftline when you don't answer. One dial code, two minutes, tested with you before it goes live.
