Central heating repairs in London and Hertfordshire

Your central heating can unfortunately go wrong at any time. To prevent this, you should make sure you service your boiler regularly and have your central heating checked as often as possible.

Common central heating faults that can occur are

  • Blockages
  • Build up of limescale or sludge
  • Slow leaks from pipe joints and fittings
  • Loss of system pressure resulting in boiler shutdown

Regular servicing of your central heating can reduce the risk of problems in the future

Our gas safe registered installers are trained and qualified to diagnose faults before they happen. We can perform planned preventative maintenance to your central system to prolong it's life, and diagnose faults in the system. As installing a new boiler can be expensive and time-consuming, we recommend a central heating inspection quarterly.

When you call us regarding a central heating fault, we will attend your property as soon as possible. Many problems can be solved on the first visit, however if this is not possible we will provide a full estimate of remedial works to be carried out with a breakdown of costs and details of any central heating parts that need to be replaced.

Often, problems can be caused by a build up of sludge in your radiators. This can affect your heating's performance and cause blockages. When this is the case, we recommend a full powerflush which will be carried out by our qualified and experienced personnel.

Service your boiler like you service your car

Many people don't realise that a boiler is very much like a car. It has parts inside it that wear and break down with time. It has a combination of mechanical and electrical systems that can develop faults in time. Because of this, it is essential that you carry out planned preventative maintenance to your boiler regularly. We recommend a boiler service at least once a year. In addition to this, just like you change the oil on your car, you should add inhibitor to your central heating system and install a sludge reducing system such as a MagnaClean to your existing or new installation.

email us at or call us on 01923 254173 to arrange a boiler service, planned preventative maintenance, or to report a fault with your central heating.
