One man and a van, 1986. A South West institution, today.
In July 2026 Gregor Heating celebrated 40 years in business. The work has changed — boilers gave way to heat pumps, then to solar PV with battery storage — but the model hasn't: a surveyor visits, the quote is free with no obligation and no hidden extras, and the engineers who fit your system are the ones who answer when you call. We're proud to be a Which? Trusted Trader, and most of our work still arrives the old-fashioned way: word of mouth.
“Excellent service from Gregor from start to finish.”

Boiler service & repair
Thorough annual servicing by engineers who remember your system from previous visits. Faults are traced properly — one customer watched an engineer patiently find a minute crack others had missed, and sort it.
- Annual servicing
- Fault diagnosis
- All major brands
Heat:Plan maintenance
Our annual maintenance cover: the office reminds you when servicing is due, contracts are good value and give peace of mind, and call-outs are prioritised for members — handled by local staff on standby rotas, not a national queue.
- Scheduled reminders
- Priority call-outs
- Peace of mind
Gas safety certificates
Landlord checks on boilers and gas hobs: booking with helpful reminders, engineers who welcome questions, testing completed without drama and without up-selling, payment online, paperwork prompt.
- Landlords
- CP12
- No up-selling
Electrical services
The greener home needs more than heat: shower installations, and the electrical work that supports heating and renewable upgrades — explained clearly as it's done.
- Showers
- Heating electrics
- Renewable support
Renewables
Air source and air-to-air heat pumps, solar thermal, solar PV with inverter and battery storage. A surveyor assesses whether the technology suits your home before you invest — then design, installation and handover done to the standard our reviews describe as "first class".
- Air source heat pumps
- Air-to-air
- Solar PV + battery
- Solar thermal
Not the cheapest. Not the dearest. Probably one of the best.
That's a customer's verdict on our annual servicing — "work always carried out with care, tidiness and efficiency", every call-out handled promptly, every follow-up dealt with courteously. It's also the whole business philosophy in one sentence.
Local knowledge matters when your boiler fails in January: our engineers live here, the office that books your service is the office that chases your follow-up, and the engineer who fitted your heat pump is the one who comes back to maintain it.

Survey. Quote. Fit. Aftercare.
Survey
A surveyor visits your home — or quotes online — to understand the property and the existing system. For renewables, this includes an honest assessment of whether the technology suits your situation.
Fixed quote
Free, no-obligation, no hidden extras — guaranteed. Finance and flexible payment options laid out plainly.
Installation
Our own engineers, quickly, with no mess — tanks removed, pipework moved, system commissioned, and everything explained.
Aftercare
A brilliant handover, servicing reminders from the office, Heat:Plan available, and local engineers on standby rotas.
No heating? No hot water?
Breakdowns don't keep office hours. Call-outs and emergencies are handled promptly — the advantage of a local company with local knowledge and local staff on call-out and standby rotas.

Asked often.
- How much does a new boiler cost?
- It depends on your home — the survey is free. We quote in person or online, no obligation, no hidden extras guaranteed, with finance and flexible payment options. The only honest price is measured against your property.
- How long does installation take?
- Usually a day; complex jobs take two. One recent job — new boiler, tank removals, pipework moves — was finished over two days: quick, no mess, and the neighbours complimented the workmanship.
- Do you install heat pumps and solar?
- Yes. Air source and air-to-air heat pumps, solar thermal, and solar PV with inverter and battery storage. A surveyor first checks the technology actually suits your home.
- What is Heat:Plan?
- Our annual maintenance cover. Scheduled servicing with office reminders, good-value contracts, and priority call-outs from local engineers on standby rotas.
- Can you do landlord gas safety certificates?
- Yes. Reminders, no-drama testing with no up-selling, online payment, prompt paperwork.
