Boiler installation in Bromley

A like-for-like combi swap starts at £1,950 supplied and fitted. Converting from a conventional system with tanks and a cylinder runs from £2,850, and removing a back boiler from £3,200. The variables are whether the boiler moves, whether the gas supply pipe needs upgrading and what condition the existing system is in — which is why we survey before quoting rather than giving a number over the phone.

A straight combi swap in the same position is a single day, with the heating back on that evening. A conventional-to-combi conversion is two days. Back boiler removals and relocations run to two or three, because there is building work around the old fireplace or new pipe runs to make.

It comes down to bathrooms and mains pressure. One bathroom and decent pressure, a combi is almost always right — no tanks, no cylinder, hot water on demand. Two or more bathrooms, or a household that all showers in the same hour, and a system boiler with a cylinder will serve you better. We check the incoming mains flow rate during the survey rather than guessing.

Not normally — a boiler replacement is covered by Building Regulations rather than planning, and we notify Building Control through Gas Safe within thirty days. Conservation areas are the exception worth knowing about: in Chislehurst, Keston and parts of Bickley there are restrictions on what can appear on a visible elevation, which affects where the flue can go. It is nearly always solvable, but it is better known before installation day than on it.

Boiler Plus has applied to every gas boiler installed in England since 2018. It sets a minimum efficiency of 92% and requires time and temperature controls. On a combi install you also need one of four extras: flue gas heat recovery, weather compensation, load compensation, or smart controls. It is included in our quotes as standard — if a quote you are comparing does not mention it, ask why.

Worcester Bosch, Vaillant, Ideal, Baxi and Glow-worm. We are not tied to one manufacturer, so we recommend on the property rather than on what earns us the most. Worcester and Vaillant carry the longest warranties and the best parts availability locally, which matters more than the badge when something needs fixing in five years.

Between 5 and 12 years depending on the manufacturer and model, and we register it for you on the day so it actually starts. On top of that we guarantee our own workmanship for 12 months. Warranties are conditional on an annual service being carried out and logged, so keep the servicing up.

Usually yes. Radiators rarely need replacing just because the boiler has been, provided they are sound and the system is clean. Two things do need checking: whether the existing radiators are big enough for a modern condensing boiler running at lower flow temperatures, and whether the property is on microbore pipework, which is common in Penge and Anerley terraces. Microbore blocks easily once a system has sludged, and it can restrict flow enough to be worth addressing at the same time. We check both at survey rather than finding out when the new boiler underperforms.

Usually, yes — but the honest answer depends on the repair in front of you. If a fifteen-year-old boiler needs a heat exchanger or a gas valve, you are spending several hundred pounds on a unit near the end of its life, and that money is better put toward a replacement. If it needs a thermocouple or a pump, repair it and carry on. We will tell you which situation you are in, including when the answer is that a repair makes more sense than the bigger job. Beyond about twenty years, parts availability becomes the deciding factor more than the fault does.

Four things, and you should have all of them before we leave. A Benchmark logbook, completed and signed — this is what validates the manufacturer warranty. A Building Regulations compliance certificate, which follows once we notify Building Control through Gas Safe within thirty days. The manufacturer warranty registration confirmation. And your invoice showing the Gas Safe registration number, which for us is 919881. If an installer cannot produce these, the installation has not been notified and you may have trouble at the point of sale on the property.

Possibly, under the ECO4 scheme, which is funded by the energy suppliers rather than by us. It generally requires someone in the household to receive a qualifying benefit and the property to have a poor energy rating. Bromley Council also runs support schemes that change from year to year. We are not an ECO4 installer, so we will not be the ones fitting a grant boiler — but if you think you might qualify, it is worth checking before paying privately, and we will say so rather than quote over the top of it.

No. Any work on a gas appliance has to be carried out by a Gas Safe registered engineer — it is a legal requirement under the Gas Safety (Installation and Use) Regulations, not a trade preference. Unregistered gas work is a criminal offence, it invalidates your home insurance and it will not be notified to Building Control, which causes problems when you come to sell.

Yes, and most of the Bromley town centre and Penge flats we work in take a combi well. The two things worth checking first are the incoming mains flow rate, since a combi on weak pressure is a poor experience, and whether the flue can terminate somewhere compliant. Leaseholders should also check their lease before work starts — some require freeholder consent for a flue on an external wall.
