Bexley homes tend to be family properties on system boilers, cylinders and larger radiator circuits. That is exactly the work we specialise in, proper sizing, G3-qualified cylinder work, and installs that are still running quietly a decade later.
Free written estimates in Bexley. £80 minimum labour if you go ahead.
Bexley (the village and the wider DA5/DA6/DA7 belt) is dominated by 1930s and post-war family homes, with a steady share of larger detached properties on system boilers feeding unvented cylinders. That is where G3 qualification, correct heat-loss sizing and proper commissioning really matter. It is not the sort of work you want done by whoever answered the phone first.
About 5 miles from our Plumstead base · approx 15–20 minutes on a normal traffic day.

A complete central heating system designed around your home, from heat loss calculation and boiler sizing through radiators, zoning, controls and commissioning. One team, one accountable install, warrantied in writing.

A new bathroom without the six-trades chaos. Danny sits with you, sketches the layout, sources fittings, then plumbs, tiles and finishes with a small trusted team, clean site, agreed timeline, one point of accountability from first sketch to final silicone bead.

Cold radiators, no hot water, an F1, F22 or E133 lockout code, we've seen every fault on every major boiler over the last 30+ years. Fixed-price diagnostic, honest recommendation on repair versus replace, no upsell.

A proper high-flow reverse flush that strips a decade of magnetite sludge out of your radiators and pipework, restoring flow, quieting the boiler, cutting gas bills, and unlocking manufacturer warranty on any new install.

Local heating and plumbing issues are rarely random. They follow the era of the property, the pipework, the water conditions and the way the house has been extended. Here is what our diary in DA5, DA6, DA7 actually looks like.
It is common to find Bexley family houses with a boiler that was picked to be cheap rather than adequate for the property. We do the heat-loss calculation and quote the right output, honestly.
Unvented (pressurised) cylinders are legally notifiable and must be worked on by a G3 qualified engineer. Danny holds that qualification, so installs, replacements and annual services are done correctly with the paperwork.
A classic 1930s semi symptom. Usually a balancing and radiator-sizing issue rather than a boiler fault. We test, balance and only recommend replacement when it is genuinely needed.
Adding a second bathroom to a Bexley family home is one of the most common projects we take on. Danny will design the pressure, capacity and pipe layout so both showers can actually run at once.
20+ years of magnetite build-up in older radiators is standard in DA5. Power flushing plus a magnetic filter usually restores full output without touching the boiler.
Speak to Danny or the office team direct on 07956 994429. Describe the problem or the project in Bexley, we'll tell you what we need to see.
For anything bigger than a diagnostic, we survey the property and send a fixed, written quote. No sales pressure and no vague phone-guess pricing.
