Boiler Work Done Properly, by People Who Only Do Boilers
Most heating companies are general plumbers who fit boilers between bathroom jobs and dripping taps. BoilerSense is different. We are a dedicated boiler specialist — everything we do, every day, involves boilers. Our engineers are manufacturer-trained by Worcester Bosch and Vaillant, and between them they have seen every fault, every model, and every installation scenario across Kent and South East London.
That single-minded focus matters when your heating fails in January, when you need a new boiler fitted right first time, or when you are a landlord who needs a gas safety certificate issued before a new tenancy begins. You get engineers whose entire working knowledge is boilers, not a general tradesman who will try his best.
We cover DA11 Northfleet and Gravesend, DA1 and DA2 Dartford, DA14 and DA15 Sidcup, DA5 through DA7 Bexley, SE18 Woolwich, and SE10 and SE3 Greenwich. Fixed-price quotes. No hidden costs. All work Gas Safe certified.
About BoilerSenseOur Boiler Services
Every service we offer is boiler-specific. No distractions, no generalist trade-offs — just deep expertise in heating systems.
Boiler Installation
Replacing an old, inefficient boiler with a new A-rated combi or system boiler is one of the most cost-effective investments a homeowner can make. We install Worcester Bosch, Vaillant, Baxi, and Ideal boilers — all with full manufacturer warranty registered on your behalf. Prices from £2,700 fully fitted.
View boiler installation details ›Boiler Repair
When your boiler stops working, you need someone with the expertise to diagnose it fast and the parts on the van to fix it. Our engineers carry a comprehensive stock of common components — diverter valves, pumps, PCBs, pressure relief valves — so the majority of repairs are completed in a single visit.
Book a boiler repair ›Boiler Servicing
Annual servicing keeps your boiler running efficiently, maintains your manufacturer warranty, and — for landlords — is a legal requirement. A BoilerSense service takes approximately one hour, includes a full combustion analysis and safety check, and results in a signed service record. From £85.
Book an annual service ›Gas Safety Certificates (CP12)
Landlords are legally required to hold a valid CP12 gas safety certificate for every gas appliance in a rented property. We issue same-day certificates across all our service areas. From £75 for a single appliance. Portfolio landlord packages also available.
Book a CP12 certificate ›Emergency Boiler Repair
No heating, no hot water, or a gas leak concern — we offer same-day emergency callouts across Kent and South East London. Call 01474 632 158 now. Our engineers are based locally and can reach most of our service area within a matter of hours.
Emergency callout information ›Boiler Service Plans
An annual service plan gives you peace of mind that your boiler is maintained, covered for breakdowns, and serviced every year without the hassle of remembering to book. Plans start from £9.99 per month and include your annual service, priority callout, and parts cover.

It is a fair question. There are dozens of plumbers and heating engineers in Kent and South East London who will fit a boiler. Here is why it matters that BoilerSense does only this:
A boiler-only engineer has diagnosed the same fault dozens of times. A generalist engineer may have seen it twice. When David H in Woolwich called us after two other companies failed to find the fault, our engineer diagnosed a hairline crack in the heat exchanger within 30 minutes.
Our engineers are formally trained and accredited by Worcester Bosch and Vaillant. That accreditation allows us to offer extended manufacturer warranties — up to 12 years on certain Worcester Bosch models — that unaccredited installers cannot provide.
We quote a fixed price before we start any work. No hourly rate that expands on the day. No surprise extras after the job is done.
Every engineer at BoilerSense is individually Gas Safe registered. All work is documented and certified. We will never ask you to accept verbal reassurance in place of paperwork.
