We clear sludge, rust and debris from central heating systems across Wandsworth — cold radiators in Battersea and Putney’s older period systems, noisy boilers in Wandsworth Town and Nine Elms flats, and uneven heating across multi-radiator systems in Earlsfield and Tooting’s terraces. Fixed price, 12-month guarantee.

Sludge and rust build-up inside radiators and pipework is one of the most common causes of poor heating performance. Here’s what tends to prompt a power flush across the borough.
A radiator that's cold at the bottom but warm at the top is a classic sign of sludge settling inside it — common in older central heating systems across Battersea and Putney's period houses that have never been flushed.
Uneven heating across a multi-radiator system, where some rooms stay cold while others work fine, often points to a blockage restricting flow to specific radiators.
Kettling, banging or gurgling noises from the boiler or pipework in flats around Wandsworth Town and Nine Elms are often caused by sludge restricting flow through the heat exchanger.
Dark brown or black water when bleeding a radiator is a clear sign of internal corrosion and sludge build-up throughout the system, common in older properties across Earlsfield and Tooting.
A thorough survey and insulation service, carried out at a fixed price before any work begins.
We assess your radiators and boiler to identify which parts of the system are affected by sludge or blockages.
You receive a fixed price covering the full flush and any inhibitor top-up before any work starts.
A powered pump forces cleaning fluid through the system to break down and remove sludge, rust and debris from every radiator.
We test heat output at every radiator and add fresh inhibitor to protect the system, covered by our 12-month guarantee.
Cost depends on the number of radiators and severity of the blockage. All prices are confirmed before we attend — no call-out charge.
Standard flat or terraced house system
Larger semi-detached or detached house
Large properties with extensive heating systems
Isolated cold spot on one radiator only
Added protection following a flush
Required before some new boiler installations
Fast arrival for power flushing across SW11, SW12, SW15, SW17 and SW18 — without the delays of London-wide dispatch.
We check heat output at every radiator before and after the flush, not just a general system clean, so you can see the improvement.
From Battersea's older unflushed systems to Wandsworth Town's newer boiler installs — we know the common causes of sludge build-up in each.
The same fixed pricing applies whether you're in SW11 Battersea or SW15 Putney. No zone uplift, no call-out charge.
A 4.9★ rating from local customers on both Trustpilot and Google.
All power flushing work carries our 12-month workmanship guarantee, issued in writing before we leave your property.

Radiators in our Battersea house had been cold at the bottom for years, we thought it was normal. Power flush made a huge difference, every radiator now heats fully across its whole surface.
Boiler in our Wandsworth Town flat kept making banging noises. Turned out to be sludge in the system, flushed it through and the boiler runs completely silently now.
Had a new boiler going into our Earlsfield terrace and were told the old system needed flushing first to protect it. Done quickly and the new boiler’s been running perfectly since.
Yes. We cover the entire Wandsworth borough including Battersea, Clapham Junction, Putney, Wandsworth Town, Balham, Earlsfield, Tooting and Roehampton — postcodes SW11, SW12, SW15, SW17 and SW18. Our engineers are based locally across South West London.
A power flush for up to 6 radiators starts from £360. For 7 to 12 radiators it starts from £480, and for 13 or more radiators from £620. A single radiator flush for one cold spot starts from £95. All prices are confirmed before work begins.
Common signs include radiators cold at the bottom but warm at the top, some radiators not heating at all, a noisy or banging boiler, or discoloured water when bleeding a radiator. If you're seeing any of these across your Wandsworth home, a flush is usually the fix.
Often, yes. Installing a new boiler onto an old, sludged-up system can damage the new heat exchanger quickly. Many manufacturer warranties require evidence of a power flush before installation, which is common practice ahead of boiler installs across Wandsworth Town's flats.
No. There is no call-out charge, no zone surcharge and no area uplift for any postcode within Wandsworth. Our fixed prices are identical whether you're in Battersea or Putney.
A standard flush for up to 6 radiators takes around 3–4 hours. Larger systems with more radiators can take up to a full day, depending on the severity of the blockage.
A professional power flush uses controlled pressure suited to your system and is safe for the vast majority of central heating setups. Where pipework is very old or fragile, we'll flag this during the survey and advise on the safest approach before starting.
Same-day survey across SW11, SW12, SW15, SW17 and SW18. Fixed price before we start. 12-month guarantee on every job.
We also cover these neighbouring boroughs — same fixed prices, same-day availability.
