Working in Ealing
Ealing homes and heating systems
Ealing is largely Edwardian and 1930s family housing with loft conversions and rear extensions added over time. Extended homes often outgrow their original boiler output, so heat-loss checks and radiator sizing matter as much as the boiler itself.
West London family homes, HMOs and new installs.

Power flushing
Power Flushing (MagnaClean System)
Get a quote for a power flush to clear sludge from your central heating system.
Signs you may need one
- Banging or kettling noises
- Lukewarm radiators or hot water
- Leaks or dropping boiler pressure
- Constant thermostat adjusting

Why it matters
Corrosion inside radiators, pipes and joints creates sludge that blocks water flow, reduces efficiency and pushes up energy bills. Filters catch loose debris, but only a chemical flush removes sludge and rust that's settled into the pipework and radiators.
A clean system can let radiators produce up to 47% more heat for the same energy use — and it protects new boilers, since 60% of first-year boiler breakdowns are caused by sludge. Fitting a new boiler on top of a dirty system just means the sludge damages it too.

FAQ
Ealing — common questions
How much does a power flush cost in Ealing?
Pricing is by radiator count, starting at £350 for up to six radiators (we don't charge VAT). Cylinders and each underfloor flow/return valve count as one radiator, which matters for larger Ealing systems.
Does my Ealing property actually need a power flush?
Look for banging or kettling noises, lukewarm radiators, dropping boiler pressure or constant thermostat adjusting. Loft-converted flue runs are checked for an inspection hatch first
How long does a power flush take in a home like mine?
Most Ealing jobs are a single day. Ealing is largely Edwardian and 1930s family housing with loft conversions and rear extensions added over time. Extended homes often outgrow their original boiler output, so heat-loss checks and radiator sizing matter as much as the boiler itself. Larger or heavily sludged systems can run longer, and we'll tell you before we start.
How quickly can you get to Ealing?
Ealing runs are grouped in the morning and early afternoon so we can cover multiple W-postcode calls in a day.

David O.
Ealing
“Booked a landlord gas safety check. Punctual, tidy and the certificate was in my inbox the same afternoon. Priced exactly as quoted.”
Sarah M.
Hampstead
“Boiler died on the coldest night of the year. They arrived within two hours, diagnosed it straight away and had heating back on before midnight. Genuinely lifesavers.”
Priya K.
