Boiler Installation in Dulwich — What Dulwich Homeowners Need to Know
DRMB Plumbing & Heating serves Dulwich and the wider SE21/SE22 area. Dulwich has a large stock of period Victorian and Edwardian properties — many with older system boilers and hot water cylinders. We specialise in like-for-like replacements and combi conversions, handled cleanly with fixed pricing.
Whether you're in Dulwich Village, East Dulwich, West Dulwich, Herne Hill, or Tulse Hill, our Gas Safe registered engineers carry out boiler installations to a high standard. Every installation is notified to Gas Safe and fully certified. Dulwich is a predominantly owner-occupier area with a high concentration of large period homes — we're experienced working in properties where the original heating system was designed around gravity hot water and may not have been touched in decades.
When Is It Time to Replace Your Boiler in SE21 or SE22?
Boiler is 10+ Years Old
Older boilers run at significantly lower efficiency. A modern A-rated condensing boiler can cut your gas bills by up to 30% compared to a unit fitted before 2010.
Repair Bills Mounting
If your annual repair bill is approaching £300–£400 or you're on a third repair in 18 months, a new boiler is usually the better financial decision.
Unreliable Hot Water
Intermittent hot water, banging from the pipes, or a pilot light that keeps going out — all signs your boiler is struggling and replacement may be closer than you think.
Parts No Longer Available
Some older boiler models become obsolete — when replacement parts can't be sourced, installing a new unit is the only practical solution.
What's Included in a DRMB Boiler Installation in Dulwich
Every boiler installation we carry out across SE21 and SE22 includes the following as standard:
Boiler Brands We Install in Dulwich
We supply and install all the leading brands. Our engineers are accredited installers for Worcester Bosch and Vaillant — which is why we can offer extended warranties of up to 10 years on these brands. We also install:

Dulwich's large Victorian and Edwardian detached houses often have multiple bathrooms and higher hot water demand than smaller properties — we take this into account when recommending a boiler output. Many properties on roads like Burbage Road, Calton Avenue, and around Dulwich Park still have original gravity-fed system boilers with separate cylinders in airing cupboards. We handle these combi conversions routinely. We don't push a particular brand; we recommend what's right for your property.
How Much Does a Boiler Installation Cost in Dulwich?
Boiler installation prices in Dulwich depend on several factors: the boiler model, whether you're doing a like-for-like swap or relocating the unit, and the condition of your existing pipework and flue. As a rough guide:
| Installation Type | Typical Price Range | Timescale |
|---|---|---|
| Like-for-like combi swap (standard location) | From £2,495 | 1 day |
| Combi swap — premium brand (Worcester Bosch / Vaillant) | From £2,200 | 1 day |
| System boiler to combi conversion | From £2,500 | 1–2 days |
| Boiler relocation (moving position) | From £2,800 | 1–2 days |
Prices are indicative and depend on your specific property and chosen boiler model. All prices include boiler supply, installation, system flush, Gas Safe registration, and manufacturer warranty registration. We provide a fixed written quote before any work begins.

This saves a separate appointment and gets you fully compliant from day one. We also offer annual landlord gas safety packages to keep your properties covered year on year.
Keep Your New Boiler Running Efficiently
Once your new boiler is installed, most manufacturers require annual servicing to maintain the warranty. We offer annual boiler services in Dulwich from £90 (or £160 combined with a CP12). Book your first service at the time of installation and we'll diary the reminder for next year.
