Boiler repair in Dulwich
- Large houses where the boiler cannot keep up because the system was never resized for extensions
- Long pipe runs that lose heat before reaching the far end of the house
- Original systems in single-occupation family homes running well past their efficient life
Big Dulwich houses often keep the boiler in a cellar or basement utility room, and some older units there are open-flued, drawing combustion air from the room itself. That makes ventilation part of any repair. If a cellar has been tanked, sealed or turned into a gym, the boiler may no longer get the air it needs, and we will tell you. Many of these homes run a system boiler with a large cylinder and two or three heating zones, and a lot have had smart thermostats wired into older control centres. Faults in that wiring and in the zone valves are common, and easy to mistake for a boiler problem. Where a repair would move or add a flue terminal on the outside of the house, check whether the Dulwich Estate scheme of management covers your property before agreeing to it. Parking is rarely a problem on these roads.

Common questions
Do you cover Dulwich?
We do. Dulwich falls within Southwark, covering the SE21, SE22, SE24 postcodes, and our engineers are out across Greater London from our Fulham office every day.
My boiler runs constantly but the far end of the house is never warm. Is it failing?
Often not. In a large house that has been extended, the more likely story is a system asked to heat more than it was sized for, or a balancing problem where the near radiators take everything. Both are fixable without a new boiler, and we would look at that before quoting for one.
We fitted a smart thermostat and now the boiler behaves oddly. Is it broken?
Probably not. Smart thermostats are often wired into an existing control centre set up for a different kind of switching, and one small mistake can leave a zone valve open, the pump running on, or the boiler firing when nothing is asking for heat. In large Dulwich houses with several zones, that produces confusing symptoms. We check the wiring against the controls before assuming any boiler part has failed.
What does it cost?
You will have a price for the work before an engineer starts. If something behind the wall changes the scope, we pause and talk it through with you rather than carrying on and billing you afterwards.
