Your safety is important to us, which is why we only employ Gas Safe registered engineers, who are highly experienced when it comes to resolving a large variety of boiler breakdown issues so whether you are experiencing a loss of heating or hot water, our professional engineers will be able to locate the root of the problem and repair your central heating system as quickly as possible.

Annual boiler service

To ensure your boiler is safe and working as efficiently as possible, it's important that it's serviced annually. It's worth noting that a boiler that isn’t serviced annually may not be covered by the manufacturer’s warranty. We will carry out a full boiler service quickly and efficiently, with the minimum of fuss.

Our fully trained and specialist engineers cover properties in Swansea, Cardiff, Newport and Merthyr Tydfil. 


If you've moved into a new home or are looking to restore lost circulation and efficiency to your central heating system, you may wish to consider a powerflush. This will replace dirty water with chemically-treated water that includes corrosion inhibitors. Any excess sludge, rust and debris will be removed, helping to guard your system against similar problems in the future.

A powerflush works by replacing the existing dirty water with chemically-treated liquid that contains advanced corrosion inhibitors that will help prevent blockages in the future.
