What is a Power Flush?

A power flush is a comprehensive cleaning process for your central heating system. It involves circulating high-strength cleaning agents through your system to remove sludge, rust, and other debris that can accumulate over time. This build-up can cause your system to work less efficiently and potentially lead to costly breakdowns.

87% of boiler breakdowns are a result of dirty water in your system

Help prevent breakdown and reduce your heating bills by up to 20% with our system power flush and FREE boiler service offer.

The offer runs for a limited time only. Don’t miss out.

Pimlico engineer
Boiler replacement and radiator move very professional

James and Andrew spent 2 days replacing the boiler and replumbing radiators. Highly professional approach, keeping all their equipment tidy, insuring all replacement work was of the highest standard and fully compliant. It's not cheap, but you get real peace of mind with the work done.

Quick to reply and fix the issues in an expert manner

The engineer was very experienced and sorted out the issues very soon. I am very happy with the services!

Continuity of care is important to me, so it was a pleasure and a relief when Julian arrived to fix it.
I always appreciate his expertise and kindness .
Definitely my knight in shining armour!
Thanks Julian

Ruth Butler
Excellent service

My hot water stopped working in the morning, I called Pimlico and within 30 minutes the plumber had arrived. Lee was very cheerful and competent. He diagnosed the issues, purchased the required parts, and had everything installed & working before the end of the day. Great!

Great service from Pimlico

We needed a plumber to rectify a leak under the kitchen sink. The technician turned up exactly on time and put in a full days work. As part of this he replaced the incoming pipework, valves and flexible hoses which was necessary. His workmanship was excellent and we now have a proper, well laid out and installed water & waste system as opposed to the spaghetti that existed before. Service was excellent as it has been on previous occasions when we have used Pimlico.

Quality craftsmanship and great customer service

I have used Pimlico Plumbers for a few jobs in the past few years (mostly plumbing and electrical). Their workers are always polite, friendly, and considerate. They take care of your property and belongings (e.g. taking their shoes off in the house, covering/protecting surfaces, and cleaning after the job). Their work is thorough, of quality, and they keep you up to date through out the process. I highly recommend Pimlico Plumbers.
