Boiler Installation in Lewisham — What Lewisham Homeowners Need to Know
Lewisham SE13 has one of the highest concentrations of boiler replacement work in south-east London. The bulk of the housing stock is 1960s and 1970s council-era semis, ex-local authority flats, and Victorian terraces — properties where the original gas central heating was installed two or three decades ago and is now reaching the end of its life. We install new boilers across SE13 every week, and we know this housing stock well.
We're based in Bromley BR2 — a short drive from Lewisham. That proximity means a genuine same-week booking, an engineer who arrives when he said he would, and parts sourced from the local merchant if anything unexpected is needed mid-job. Every installation is carried out by a Gas Safe registered engineer (registration #532682) and formally notified to Gas Safe before we leave your property.
Summer is the ideal time to book a new boiler in Lewisham. Demand spikes in October and November — if you wait until the first cold snap, you're competing with emergency callouts and waiting three to four weeks for an installation slot. Booking now means you choose your date, we survey properly, and your new boiler is commissioned and running well before autumn. Don't wait for a breakdown to force the issue.
Which Boiler Suits Lewisham's Housing Stock?
The 1960s and 1970s council-built properties that make up a large part of SE13 — the semis off Algernon Road and Lewisham Road, the flats around Lewisham High Street, the terraces running south toward Hither Green — have specific heating characteristics that affect boiler choice.
These properties tend to have standard 15mm and 22mm copper pipework installed decades ago, often with some corrosion sludge in the system. They're mid-sized to larger footprints (3–4 bedroom semis are common), meaning hot water demand is moderate to high. Our most frequent recommendations for the Lewisham SE13 housing stock:
Vaillant ecoTEC Plus — Most Common Choice
The Vaillant ecoTEC range is the boiler we install most frequently in Lewisham. It handles the heat demand of a 1960s semi comfortably, its ErP A-rating reduces fuel bills from day one, and the 10-year warranty is available when installed by a Vaillant-accredited engineer. Reliable, well-supported, and straightforward to service.
Ideal Logic Max — Value Mid-Range
For homeowners who want a quality, well-manufactured combi at a more accessible price point, the Ideal Logic Max is a strong option. It carries a 7-year warranty, is well-suited to the standard pipework configurations in SE13 terraces, and is straightforward for our engineers to commission and service.
Worcester Bosch — Premium Reliability
Worcester Bosch is the premium option for Lewisham homeowners who want maximum peace of mind. Up to a 10-year warranty when installed by an accredited engineer (which DRMB is). We recommend the Greenstar 4000 or 8000 range for larger SE13 properties. The brand has the best parts availability in London if a repair is ever needed.
System Boiler + Cylinder — Larger SE13 Homes
Some of the larger council-era properties and Victorian conversions in Lewisham still suit a system boiler with a hot water cylinder, particularly where multiple bathrooms are in use simultaneously. Modern condensing system boilers are 30%+ more efficient than the units they replace and can use your existing cylinder if it's in good condition.
At your free survey, we'll assess your property, your current setup, and your hot water usage to make a specific recommendation. We don't push one brand — we recommend what genuinely suits your home and budget.
New Boiler Cost in Lewisham SE13
Boiler installation prices in Lewisham depend on a few things: the boiler model, whether we're doing a like-for-like swap or moving the unit, the condition of your existing pipework, and whether you're converting from a system boiler to a combi. As a working guide:

Lewisham Landlords — New Boiler + CP12 Bundle
SE13 has one of the highest densities of privately rented properties in south-east London. The streets between Lewisham town centre and Hither Green, around Lewisham High Street, and along Lewisham Road are home to a significant buy-to-let stock — much of it in ex-council housing with original or aging central heating systems.
As a Lewisham landlord, keeping your boiler in safe working order is a legal requirement. Under the Gas Safety (Installation and Use) Regulations 1998, you must have all gas appliances, pipework and flues checked annually by a Gas Safe registered engineer — and you must provide tenants with a copy of the Gas Safety Record (CP12) within 28 days of the check.
When your boiler needs replacing — whether it's failed mid-tenancy or is approaching end of life — we can carry out the installation and issue the CP12 at the same visit, wherever the timing allows. This gives you:
CP12 annual gas safety certificates in Lewisham: £90. New boiler installations from £2,495. Ask about the bundle when you book. See our full CP12 Lewisham page for more on landlord gas safety obligations in SE13.
For routine annual boiler servicing to keep your warranty valid and your tenants safe, see our boiler service Lewisham page. Services start at £90.

Summer installation slots are available now, with short lead times and no emergency premium. Get your new boiler sorted in Lewisham before everyone else leaves it too late.
Boiler Installation Lewisham — Frequently Asked Questions
How long does a boiler installation take in Lewisham?
A like-for-like combi swap in a typical Lewisham terrace or council-era semi takes one day — usually 6 to 8 hours including system flush and full commissioning. If you're converting from a system boiler with a hot water cylinder (common in the 1960s and 70s council properties and larger terraced houses in SE13), the job is usually 1 to 2 days. We confirm the exact timescale at your free survey so there are no surprises on the day.
Do you offer finance for a new boiler in Lewisham?
Yes. We can discuss finance options at your free survey. Spreading the cost of a new boiler installation in Lewisham SE13 over monthly payments is popular with both homeowners and landlords who want to avoid a large upfront outlay before the autumn season. Ask when you book your free quote — we'll run through what's available and what suits your situation.
What boiler brand do you recommend for SE13 / Lewisham homes?
For the typical 1960s and 70s council-era semis and terraces in Lewisham and SE13, we most frequently recommend the Vaillant ecoTEC Plus or the Ideal Logic Max — both are reliable mid-combi options well-suited to the heat demand of this housing stock. Worcester Bosch is an excellent premium choice and carries up to a 10-year warranty when installed by an accredited engineer like DRMB. We'll make a specific recommendation at survey based on your property size, hot water demand and budget — not on what earns us the most margin.
How much does a boiler installation cost in Lewisham SE13?
A new combi boiler installation in Lewisham starts from £2,495 fully installed. This includes the boiler unit, all labour, system flush, magnetic filter, flue, Gas Safe notification certificate and manufacturer warranty registration. The price is fixed at quote — no extras on the day. More complex jobs (system-to-combi conversions, pipework rerouting) are priced at free survey.
Can you install a new boiler and issue a CP12 for a Lewisham rental property at the same visit?
Yes. For Lewisham landlords, we combine the boiler installation and the Gas Safety Certificate (CP12) in a single visit wherever the timing allows. This keeps both jobs on one invoice and one scheduling slot — particularly useful for the high density of SE13 rental properties. CP12 certificates are £90. See our CP12 Lewisham page for more.
