Fill the quiet months. Catch every winter call.
Boiler work comes in waves. Dead in a warm September, then the heating goes on and every phone in the county rings at once. We give you certified replacement leads and booked surveys when you want them, and AI that answers the phone when you are under a floorboard.
Two kinds of heating customer. You need both.
Your enquiries split into two very different buyers, and most marketing treats them the same.
The distress buyer. The boiler has died, it is cold, there may be children or an elderly parent in the house. They call three installers and book whoever answers first. They want a date and a price today. Miss the call and the job is gone within the hour.
The planned buyer. An older boiler that keeps needing repairs, a bathroom refit that needs a different system, a move from a regular boiler and tank to a combi. This homeowner reads reviews, asks about finance and wants three quotes. They take weeks and go cold if nobody follows up.
The distress buyer needs speed. The planned buyer needs patience. A small firm rarely has both, least of all in winter.
Where heating firms leak work
- Missed calls in the cold snap. When the heating goes on in autumn, faults surface and call volumes jump. That is exactly when you are too busy to pick up.
- Quotes that just sit there. A homeowner gets a price for a combi conversion, says they will think about it, and nobody chases. By spring they have forgotten your name.
- Feast and famine. Summer is quiet for replacements, so engineers sit idle or you take on low-value work to cover wages.
- Shared leads. Lead sites that sell the same enquiry to four firms turn every job into a race to the bottom on price.
A note on grants. Most homeowners asking for a "free boiler" will not qualify for one. Straight gas boiler swaps are generally not grant funded, and the ECO4 scheme, which has funded some heating upgrades for eligible households, is due to close at the end of 2026. We do not market grant boilers we cannot stand behind, so you are not wasting surveys on people expecting something for nothing.
Replacement work, checked before it reaches you.
We run campaigns through comparison sites and paid social, then certify each enquiry. That means the homeowner has replied to an SMS or spoken to us and confirmed their details and interest. Every lead is exclusive to you.
Certified boiler leads
From £20 per lead, ex VAT. The final price depends on your region and how tight your criteria are. We qualify on:
- Homeowner, not a tenant or landlord enquiring on someone else's behalf (unless you want landlords)
- Current set-up: combi, system or regular boiler, back boiler, or no working heating
- What they want: like-for-like swap, conversion to combi, full central heating system
- Fuel type, so oil and LPG enquiries only go to installers who cover them
- Timescale: broken now, within a month, or planning ahead
- Postcodes you actually cover, so no 90-minute drives
Booked survey visits
From £130 per appointment, ex VAT. Our VoiceAI calls the homeowner, confirms budget and timescale, asks whether they want finance, and books a survey straight into your diary.
- Budget range checked against the work they want
- Access, parking and who will be home confirmed
- Booked into the slots you release, nothing else
- Confirmation and reminder messages to cut no-shows
- Replaced if it is not what we agreed, reported within 72 hours
Turn campaigns up in summer when you need to fill the diary and down in January when you are flat out. No set-up fees or retainers on lead generation.
An office that never puts the phone down.
The leads are half the story. The other half is answering and following up properly when you are elbow-deep in a system flush.
VoiceAI triage on every call
Answers in under three rings, day or night. It separates "no heating, two kids at home" from "thinking about a new boiler next year", books the urgent ones or hands them warm to an engineer, and logs the rest with notes and a recording.
Quote chasing that happens
Every quote gets a polite follow-up by SMS, WhatsApp or a call: did the finance options make sense, any questions about the warranty, shall we book a date? Replies drop straight back into your system.
Autumn reactivation
Before the cold arrives, AI works through last year's unconverted quotes and old service customers with ageing boilers. A timely nudge in September fills October before the breakdown rush does it for you.
Website chat for the obvious questions
Combi or system? Will my radiators need changing? Do you offer finance? A chatbot answers from your own approved information, then asks for a postcode and books a survey.
Reminders and annual service prompts
Survey reminders the day before, and service reminders when the boiler's anniversary comes round. It keeps you front of mind for the replacement.
Job management integration
Leads, call notes and appointments land in the CRM or job management software you already use, or a spreadsheet if that is your system.

Work out what a fitted boiler really costs you to win.
Cost per lead is a vanity number. Cost per installed boiler is the one that matters. Here is how to reason about it. The figures below are invented for illustration only, not a client result. Plug in your own.
| Step | Illustrative figure | What drives it |
|---|---|---|
| Certified leads bought in a month | 50 at £25 = £1,250 | Region, fuel type, how narrow your postcodes are |
| Leads you reach and survey | 30 | Speed of first call. This is where VoiceAI earns its keep |
| Surveys that become installs | 10 | Your pricing, finance options, follow-up discipline |
| Lead cost per install | £125 | £1,250 divided by 10 |
Now ask what an install is worth to you after materials and labour, on a job that is typically a few thousand pounds for a straightforward replacement and more for a conversion or full system. If chasing quotes properly turns 10 installs into 12, your cost per install falls to around £104 without buying a single extra lead. That is why we always look at follow-up before telling you to spend more.
Leads you can call without a second thought.
Every lead comes with recorded consent. SMS and calls only happen where UK GDPR and PECR allow, numbers are screened against the TPS where required, and our VoiceAI tells callers they are speaking to an AI. Your Gas Safe registration and building control notification stay your responsibility, and we only send leads to registered installers.

Questions heating engineers ask us.
Are the boiler leads shared with other installers?
No. Every certified lead is exclusive to you. We do not resell the same homeowner to other heating firms.
Can I pause leads when I am fully booked in winter?
Yes. You set weekly volumes and can turn campaigns down or off when the diary is full. Many installers push volume in late summer and early autumn, then ease off once breakdown work takes over.
Do you generate free boiler or grant leads?
No. Straight gas boiler swaps are generally not grant funded, so we market paid replacements and finance options rather than promising free boilers. If you work on a specific funded scheme, talk to us and we will discuss whether a separate campaign makes sense.
Can you filter out oil, LPG or back boiler jobs?
Yes. We ask about the current system and fuel type on every lead, so you only receive the work you are set up to do.
What happens if a lead turns out to be a tenant?
If it falls outside the criteria we agreed, report it within 72 hours and we replace it. That is why we pin down homeowner status and your postcodes before we start.
Will the VoiceAI book emergency breakdown visits?
It can. You decide the rules. Some firms want urgent no-heat calls booked into reserved slots, others want them passed live to an engineer. Either way the call is answered, logged and recorded.
Does the AI work with my job management software?
In most cases. We integrate with common CRMs, calendars, email and spreadsheets, and our EngageAI team will check your system on the discovery call before promising anything.
