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
Hampstead — common questions
How much does a power flush cost in Hampstead?
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 Hampstead systems.
Does my Hampstead property actually need a power flush?
Look for banging or kettling noises, lukewarm radiators, dropping boiler pressure or constant thermostat adjusting. Narrow lanes mean we plan van access and parking beforehand
How long does a power flush take in a home like mine?
Most Hampstead jobs are a single day. Hampstead homes are big, tall and often listed — three or four floors, several bathrooms, and heating systems running long pipe routes with high hot-water demand. Pressurised cylinders, secondary returns and zoned controls are standard here. Larger or heavily sludged systems can run longer, and we'll tell you before we start.
How quickly can you get to Hampstead?
Hampstead is minutes from Hendon, so we can often attend urgent no-heat calls the same day.
Do you charge to visit a property in Hampstead?
An estimate visit in Hampstead is £120 as a call-out fee. If you'd rather not book a visit, we can often quote by email or over the phone once you describe the job or send photos.

Rated 5.0 out of 5 by homeowners, landlords and managing agents across North West, West and Central London.
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.”
David O.
Ealing
