I contacted Power Flush Wizard to look at our central heating system as we had moved into a new house and the system wasn’t functioning correctly. Darren came round inspected the system and immediately knew what the problem was, he advised that he shouldn’t carry out the power flush straight away as it was more important to rectify the issues with our system first, then carry out a full power flush. Darren moved work around to fit us in and went through and rectified all issues we had, recommending system improvements and enhancements we could consider carrying out to make the system more efficient and run more smoothly, we took him up on these recommendations and when completed, we had a full power flush carried out and the central heating system has never worked better. I cannot recommend Darren and Power Flush Wizard highly enough, his prices were competitive, his work was to the highest standard and in this day and age, it is so refreshing to find a skilled tradesmen who does what he says he is going to do.

Frank & Ben did a fantastic job on a very thorough powerflush of a 31 radiator house. They worked a long hard day that has paid off massively - radiators that haven't been hot in a year are now piping hot again. Should have done this years ago! Massive thumbs up.



We had power flush done and was really impressed with the service. Our radiators heat up so quickly now and seem to radiate more heat . Clean efficient and well worth having system flushed



Had issue with Radiators not warming up contacted Darren at Power Flush wizard he came round and checked everything tested the system and a power flush was needed since having done I don’t have any issues the job was done to the highest standard and nothing was too much trouble would use again.



We had problems with our heating system for a long time and was advised having a power flush. Incredible service, from start to finish, we now have a warm home again thanks to Darren.



Very pleased with our new boiler. The work carried out by Darren was to an excellent standard, he arrived on time, cleared up any mess created and was very polite and friendly. I would not hesitate in using Wizard Gas Services again in the future and would highly recommend them.



Darren was a very friendly chap did a fantastic job radiators now heat up within 5 mins of switching on. He persevered as the system has never been power flushed before, even the radiators that didn’t work. Well recommended and I like the fixed price, you know what you pay.



We found Darren a friendly, helpful and efficient engineer.

Mrs Yusef


Top job - the engineer came the day after I called, and I am pleased with the results of the power flush. The engineer replaced a few radiator valves at the same time too, good all round service.

I would like to thank your company so very much for firstly coming out to my property on Easter Sunday. Secondly, for the amazing man you sent my tenants couldn't praise him enough. He went out of his way to help the family get heating and he noticed things my Britsh Gas man had not noticed the day before. I am very grateful to him. Please could you pass on my thanks to him.

J Drake


The engineer was fantasic, very thorough and very polite. We were recommended a power flush by British gas before having our new boiler. We would be happy to recommend Power Flush Wizard to anyone in the same boat.

Our engineer was fantastic, our microbore pipes were solidly blocked but he managed to get the heating working better than it ever has done while we have lived here! Thank you!

The flat has never been so warm, I have happy tenants. I will be using Power Flush Wizard to clean the radiators in all my rental properties in future.

Nicola Grant


Steve was fantastic. Got the job done, which was no easy feat with our ancient central heating system!

Mr & Mrs Jenkins


We were recommended a power flush by British gas after having a new boiler, so we got in a few quotes. Not only was Power Flush Wizard the most competitive quote, we got a guarantee too! The job was carried out over a weekend too, so I didn't need to take time off work. Highly recommended Power Flushing firm!

Mr Thompson


I just wanted to write to you to let you know how impressed I was with the power flush service I received at the above address last Saturday (May 4th 2013). Your engineer arrived at 8pm like he said he would and worked like a Trojan until 5pm, he was very helpful showing me the state of my system and what he had done to improve the water flow. He even advised me on the best settings to have my boiler at so it saves me money on my gas bills. He cleaned up afterwards and couldn’t have done a better job so please pass on my thanks.

Mathew Miles


May I take this time to express how impressed we were with Darren's customer service and knowledge. We will definitely recommend power flush wizard to friends and family and also use your services in the future. Hope you will pass on our comments to Darren from us.

Mr & Mrs Da Silva

Hutton, Essex

Raz worked tirelssly from start to finish! It was a long day, but he didn't leave until the heating was back on! Highly recommended.

Mrs Cooper


My friend in Windsor told me to get in touch with the Power Flush Wizard after they done a great job power flushing her radiators. We have both been very happy with the service we received and I would certainly recommend others to have this service done.

Mrs O'Connor


My boiler was making lots of noise and cutting on and off and I wasn't sure why. I called the Power Flush Wizard and their heating engineer quickly identified the problem. After a power flush of my heating system I could not be happier with the service I received and the resulting reduction in my fuel bills.

D Carpenter


I was very surprised at how much better our heating system worked after Darren completed the power flush. We live in a big house with 16 radiators and the difference has been incredible. Our heating bills have gone down by at least 20%. I have already recommended Darren to a number of people I know and they have also been impressed with the results after power flushing.

Powerflush Wizard did an excellent job, after we had had a bad experience with another company. There was far more sludge than expected and as a result the engineers stayed until 11pm to get it all out and fit a Magnaclean. In spite of this, the invoice was for the exact amount of the estimate given over the phone and significantly less than that of the previous firm. All our radiators are now working and we can highly recommend this company and its engineers.

Archie Campbell
