Types of Boiler We Install
We recommend the right boiler type for your property at the free survey stage.
Combi Boilers
Heat water on demand without needing a separate cylinder or tank. The most space-efficient option and well-suited to most Tonbridge homes — terraced properties, semis, and smaller family houses where airing cupboard space is limited.
System Boilers
Work with a hot water cylinder (no cold header tank needed). Better suited to homes with multiple bathrooms and higher simultaneous hot water demand, where a combi might struggle.
Regular (Heat-Only) Boilers
Require both a hot water cylinder and a cold water header tank. Found in older properties with traditional heating systems. We can replace like-for-like or upgrade where layout allows.

What Our Customers Say
50+ five-star reviews from homeowners and landlords across Kent.
"Absolutely professional from start to finish. The engineer arrived on time, explained everything clearly, and left no mess behind. Our new Worcester Bosch is running perfectly. Would recommend without hesitation."
"Called about a boiler fault on a Wednesday and they were with me by Thursday. Diagnosed the problem in under an hour, fixed it the same day, and gave me a fixed price before touching anything. Exactly what you want."
"Booked a Gas Safety Certificate for my rental property — same week appointment, certificate emailed before the engineer left the driveway. Efficient and professional. Will use again next year."
"Used them for CP12 inspections across three properties now. Always on time, always professional, certificates issued same day. Exactly what a busy landlord needs."
"Had the whole central heating system replaced after moving into an older house. Brilliant job — finished on time, no mess, and the Nest thermostat they installed is brilliant. Very pleased."
"Power flush made a huge difference — radiators that were barely warm are now fully heating. Should have done it years ago. Fair price and good communication throughout."
Frequently Asked Questions
How much does a boiler installation cost in Tonbridge?
A new combi boiler installation in Tonbridge typically costs between £2,500 and £4,500 including supply and fitting. The price depends on the boiler brand, whether pipework needs alteration, and whether you are replacing like-for-like or relocating the boiler. We offer fixed-price quotes after a free survey.
How long does a boiler installation take?
Most straightforward boiler replacements take one full day. If you are switching from a regular boiler to a combi, or if significant pipework alteration is needed, the job may take two days. We confirm the timeframe in your quote.
What warranty do I get on a new boiler?
We install Worcester Bosch, Vaillant, Ideal, and Baxi — all offering up to 12-year manufacturer warranties when installed by an accredited engineer. All installations also carry a 12-month workmanship guarantee from Boiler Fit Direct Kent.
Should I replace my boiler if it is over 20 years old?
A boiler over 20 years old likely converts only 70–80% of its fuel into heat, compared to 90%+ for a modern condensing boiler. In most cases replacement is more cost-effective than ongoing repairs. We give honest advice on whether repair or replacement makes more financial sense.
Will gas boilers be banned after 2025?
No. There is no ban on replacing existing gas boilers. The 2025 proposals applied to new-build homes only, and even that was delayed. Existing homeowners can continue to use and replace gas boilers. It remains perfectly legal and practical to replace a faulty boiler with a new gas model.
What boiler brands do you recommend?
We install Worcester Bosch, Vaillant, Ideal, and Baxi. Worcester Bosch and Vaillant are generally considered premium options with the longest available warranties. Ideal and Baxi offer excellent value at a lower price point. We recommend the right brand for your property type and budget at the survey stage.
