“CH system needed a power flush. It couldn't have gone any better: good communication, quick response and quick appointment. Turned up on time, job done, no fuss. Highly recommended, and that doesn't come easily from me.”

Peter Bartholomew

“Really quick to come out after the initial phone call. Radiators and valves were fitted perfectly and the place was left tidy before he left. Friendly, professional and fairly priced.”

“Made time for me during a busy season, not leaving me and my family in the cold. Able to get the parts and fit them the same morning. Would recommend.”

Common questions, plain answers

What's the difference between a power flush and a chemical flush?

Power flushing uses a pump to physically scour the system at low pressure. Chemical-only is cheaper but slower and won't shift heavy sludge.

How much does a system flush cost?

Chemical clean is £150 to £200. Full power flush £400 to £600 depending on radiator count.

How often should I flush my heating system?

Most systems benefit from a chemical clean every 5 to 7 years. Power flush only when needed (sludge, cold radiators, new boiler install).

Do new boiler installations need the old system flushed?

Yes. Manufacturer warranties usually require it. Installing a clean boiler on a dirty system invalidates the warranty.
