Most Sidcup homes are well suited to a modern combi boiler, and that’s what we install and recommend for the vast majority of local properties — particularly the area’s spacious 1930s semis and larger family houses, 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.

As a Vaillant Advance Mastertech installer, we can offer customers:
Sidcup’s mix of spacious 1930s semis and detached family homes often means higher hot water demand than you’d find in a typical flat or terrace.
That’s why, for the vast majority of local installations, we recommend a combi boiler — a correctly sized model can still comfortably serve multiple bathrooms, without needing a hot water cylinder taking up space in the airing cupboard.
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 Sidcup?
Boiler installations in Sidcup start from £1,643 +VAT as part of our current offer, which covers a new combi boiler — the type we install for the vast majority of local homes. The final price depends on the make and model you choose, how complex the installation is, and whether any relocation work is needed. We’ll agree a fixed price with you after a free home survey.
Do you remove my old boiler?
Yes — removing and safely disposing of your old boiler is included as standard.
How long does a boiler installation take?
Most installations in Sidcup are completed within one to three days. Relocating your boiler may take a little longer, and we’ll confirm timings during your survey.
Can you relocate my boiler?
In many cases, yes. Relocating your boiler during installation in Sidcup is often possible, provided there’s suitable pipe and flue routing. We’ll assess feasibility during our site survey.
Can I get a combi boiler installed if my property currently has a system boiler?
Yes, we can convert your system boiler to a combi, or adapt your existing pressurised setup.
Which boiler brands do you recommend?
We only fit trusted manufacturers, including Vaillant, Worcester Bosch, Ideal and Baxi. As Vaillant Advance Mastertech installers, we can also offer exclusive extended warranties and advice on the best model for your Sidcup home.
How quickly can you install my new boiler?
We can usually schedule installations within a few weeks of your quote. If your boiler has failed completely, we also offer emergency installations in Sidcup.
Do I need to upgrade my pipework or radiators?
Not always. During your survey, we’ll check your existing pipework and radiators for compatibility with the new boiler and flag any upgrades worth considering.
What size or type of boiler is right for a larger household?
Combi boilers suit small to medium-sized homes well. For larger Sidcup households with several bathrooms, we’ll advise whether a high-output combi or a system boiler is the better fit for your hot water demand.
Whether you’re replacing a tired, unreliable old boiler or upgrading to a new, more efficient system, Everest Heating & Plumbing are on hand to help.
