If you are experiencing problems with your heating system, we will undertake a fault finding service where we can assess the problem. We can then advise on the easiest and most cost effective fix.

As mentioned above we regularly install full heating systems, providing expert solutions from installation to repairs and servicing.


Central Heating

A sometimes overlooked but essential part of any home is your central heating system. New smart thermostats like Hive and Nest are changing the way we can control our central heating. Your central heating interface should be user friendly and easily adjusted so that you can maximise the efficiency of your system. This helps to provide you with the correct temperature when it’s needed; increasing comfort and saving you money.

We facilitate all central heating installations to new build properties. Working in partnership with local and national developers to deliver the most efficient central heating installations.

What if my central heating breaks down? Just give us a call on 01787 888505 we will be happy to offer a free no obligation assessment.



All our staff members are fully Gas Safe Accredited. From gas repairs to testing and certificates you are in safe hands.



Ensuring your radiators are working efficiently is key to ensuring your home is maintaining the correct temperature set on your thermostat. If you have a radiator that is not reaching full temperature it could mean it simply needs bleeding. Over time radiators can trap air from the central heating system and stop functioning as intended. We can either book a visit to do this on your behalf or advise you on how to do this safely.

Do you need new radiators installed (have you considered underfloor heating?), leaks fixed or unwanted noise minimised? We will book a visit to inspect the issue / outline your exact requirements.


Power Flushes

Over time your central heating system can build up an amount of rust or debris internally. This will prevent the water from passing through the system efficiently and in some cases can cause a blockage.

By flushing a chemical designed to remove the unwanted sludge through your pipes we can help restore optimal performance.
