Combi in the kitchen
Common in the houses here. The new boiler usually goes in the same spot with a new flue kit through the same wall.
Combi boilers · New Addington CR0
Most homes in New Addington already run on a combi in the kitchen or a cupboard, so replacing one is usually a straightforward, one-day job. We fit new combis for people who own their homes and for landlords with houses, maisonettes and flats to let.

Before you start
New Addington is largely council-built homes from the 1930s onwards, and today it’s a mix of privately owned and rented houses, maisonettes and flats. So the first question is who is responsible for the boiler.
If you own your home, including one bought from the council, the boiler is usually yours to replace. If you rent from a housing association or the council, they are responsible for your boiler, so contact them first. If you rent from a private landlord, it’s their job too, and they can ask us for a quote.
For the area in general see our New Addington page. For combis in detail, see combi boiler installation.
What we usually find
Common in the houses here. The new boiler usually goes in the same spot with a new flue kit through the same wall.
Common in maisonettes and flats. We check the new model fits the space with the clearances the manufacturer needs for servicing.
If your home still has a cylinder and loft tanks, it’s a conversion rather than a swap, and takes longer.
Landlords
With a tenant in, the aim is a short, planned job. A like-for-like combi swap usually takes a day, and we can arrange access with you or your letting agent. You get the Benchmark commissioning checklist and the Building Regulations compliance certificate, and the warranty is registered in the owner’s name.
Remember the rules that sit alongside a new boiler. Rented homes in England need a CO alarm in any room with a fixed combustion appliance, which includes the boiler. Your annual gas safety check still applies, and the tenant needs a copy within 28 days. We do those too: see landlord gas safety certificates and landlord boiler replacement.

Comparing quotes
Use this to compare any two quotes. If one is cheaper, check it isn’t simply missing something on this list.
A survey of flue, gas supply and water flow
Decides the boiler size and whether a combi will give decent showers.
“How did you size the boiler?”
System cleaned to BS 7593, with inhibitor
Sludge from the old system is the main killer of new boilers.
“Is a full system clean included?”
Magnetic system filter
Keeps catching debris for the life of the boiler.
“Which filter, and where will it go?”
Controls that meet Boiler Plus
A legal requirement in England, and it saves gas.
“Which controls are included?”
New flue kit, positioned to the rules
Reusing an old flue or a bad position can fail inspection.
“Is the flue new, and where will it exit?”
Condensate pipe protected from frost
A frozen condensate pipe is the most common winter breakdown.
“Where will the condensate drain?”
Old boiler, tanks and cylinder removed
Disposal costs money. Make sure it’s not an extra on the day.
