Highlights

Gary replaced my ancient boiler and pipes, not a straightforward job. He explained what he was doing and why as he progressed. He also did an excellent job of explaining the new heating system. Friendly, professional and above all reliable. I would recommend without hesitation.

Customer in Greater LondonWhich? Trusted Traders5.0 rating

Gary has been an absolute life saver. He helped find a blockage in one of my gas pipes which was left undiagnosed/ignored by the previous boiler company who installed the boiler. Gary gave me so much advice and guidance in dealing with the situation and I can’t thank him enough. He was extremely patient and sympathetic of my situation and was nothing but helpful throughout the process. Couldn’t recommend Gary enough.

Customer in Greater LondonWhich? Trusted Traders5.0 rating

Gary and Riley did a fantastic job fitting my new boiler and a complete central heating system. Their work is of an extremely high quality. My house was left neat and tidy each day. Both were very helpful in explaining how to operate the system. I have cancelled my contract with British Gas to use them to service the boiler each year.
