He protected the floor area with coverings prior to beginning and there was no mess afterwards. Social distance was maintained at all times."

Gas and LPG Heating

Full Gas and LPG Heating Systems Installations.

Specialising in the installation of full natural gas and LPG heating systems, from the boiler to the pipework, and radiators to valves, we take care of everything for you. 

Our engineer will meet with you at your home to discuss what you are looking for, and from there we can provide our recommendations on which products suit your needs and budget before providing a no obligation estimate of cost for the installation of your heating system. 

Use the contact form on this page to contact us and arrange an appointment.

Gas Boilers

With the latest gas boilers running more efficiently than ever, it is a popular option to upgrade your old boiler and avoid changing the entire central heating system.

We highly recommend a central heating health check to make sure your radiators are in excellent working order, and to ensure that a new boiler is the best option to keep your central heating running at its best. 

Contact us for more information or to organise an appointment with a gas engineer to discuss your requirements and receive a no obligation estimate.


LPG Boilers

LPG and LPG boilers are fast becoming a much more secure alternative energy source for homes.

We will arrange an appointment to discuss your needs and then make our recommendations to get the best out of your new heating system before providing a no obligation estimate. 

Get in touch today to see what we can do for you.

Gas Fires and Cookers

All new gas fires and cookers need to be installed by a Gas Safe registered engineer.

Our engineers are all Gas Safe registered and fully qualified to fit gas stoves, all styles of gas fires, AGAs, hobs, freestanding cookers and range cookers.

Before we install your new appliance, we make sure that all existing connections are safe and up to the current standard, and if they are not we will discuss what options are available before carrying out further work.  We will also disconnect your old appliance to make sure it is done safely.

Once your new gas appliance is installed we will provide you with the Gas Safe certification. The certification is extremely important as it could invalidate a household insurance if you have a new appliance installed without it.
