Most Sevenoaks homes are well suited to a modern combi boiler, and that’s what we install and recommend for the vast majority of local properties — though many Sevenoaks homes are larger period and Georgian-style properties near Knole Park, where getting the right type and size of boiler matters just as much as the installation itself.
Our Gas Safe Registered engineers assess every property individually, rather than assuming a one-size-fits-all solution — so if a system boiler, regular boiler, or an unvented hot water cylinder is a better fit for your home, particularly where hot water demand is high, that’s exactly what we’ll recommend.

Sevenoaks’ larger period homes, many with several bathrooms, often need a higher-output combi boiler to keep pace with demand.
Our engineers will assess your household’s hot water usage properly during your survey, rather than assuming a standard model will do.
To keep your boiler performing at its best and comply with the manufacturer’s warranty, we strongly recommend having it serviced every 12 months.
A boiler service includes thorough essential safety checks, cleaning internal components, and checking gas working pressures.
These are critically important to the safe and efficient operation of your new boiler for years to come.
We’ll remind you when it’s due each year so you don’t forget.
We know a new boiler is a significant investment, especially in circumstances when you need an unexpected replacement sorted quickly.
That’s why we offer manageable monthly finance options to ease the burden.
You can opt to either pay up front, or pay off the boiler in monthly instalments over three, five, eight or 10 years with an APR of 9.9%. We can walk you through finance during your quotes or installation survey.
How much does a new boiler installation cost in Sevenoaks?
In Sevenoaks, boiler installations start from £1,643 +VAT as part of our current offer, based on the combi boilers most local homes need. What you pay depends on the make and model, installation complexity, and any relocation work involved – we’ll confirm the exact cost with a fixed-price quote after your free survey.
Do you remove my old boiler?
Yes. We take care of removing your old boiler and disposing of it responsibly, so you don’t need to arrange anything separately.
How long does a boiler installation take?
In Sevenoaks, most boiler installations are finished within one to three days. If you’re relocating the boiler, allow a little extra time – we’ll estimate this during the survey.
Can you relocate my boiler?
Relocation is often achievable during a new boiler install in Sevenoaks, as long as pipe and flue routing allow it. We’ll check this during your free survey.
Can I get a combi boiler installed if my property currently has a system boiler?
Yes, converting from a system boiler to a combi is something we do regularly, and we can adapt your current pressurised setup as needed.
Which boiler brands do you recommend?
Our engineers only install trusted brands, including Vaillant, Worcester Bosch, Ideal and Baxi. As Vaillant Advance Mastertech installers, we can offer extended warranties and help you choose the best fit for your Sevenoaks property.
How quickly can you install my new boiler?
Installations are typically scheduled within a few weeks of your quote. If your current boiler has stopped working altogether, we offer emergency installations across Sevenoaks too.
Do I need to upgrade my pipework or radiators?
Not necessarily. Our survey includes checking your pipework and radiators for compatibility, and we’ll advise if any upgrades would improve performance.
What size or type of boiler is right for a larger household?
Combi boilers are well suited to small and medium-sized homes. For bigger Sevenoaks households with more than one bathroom, we’ll recommend whether a high-output combi or a system boiler makes more sense.
Whether you’re in a period property or a newer Sevenoaks home, we’ll help you find the right heating solution for your household.
