A powerflush is £500+VAT for up to 8 radiators, then £50 per radiator after that. We confirm the cost for your system before we start, with no hidden extras.

It is a legal requirement to have a gas safety check carried out yearly for all rental properties. We can also add a boiler service at the same time, and the total for both is £160+VAT.

Do you have experience with home insurance claims for leaks?

Yes. We have extensive experience working with home insurance providers and can provide professional reports and high-resolution photographs to back up any claim, so you are not left out of pocket.

Which air conditioning brands do you install?

We install Mitsubishi, Daikin and Samsung systems, chosen for their energy efficiency, quiet running and long-term reliability. We will recommend the right system for your space during the survey.

How much does air conditioning installation cost?

Air conditioning installations start from £1,900 + VAT, depending on the system and your property. We assess your layout and cooling needs before recommending the right size and model, then give you a clear quote.

How long does an air conditioning service take?

An air conditioning service usually takes one to two hours, depending on the location and condition of the unit. We check refrigerant levels, clean the filters and inspect all the components.

Why should I service my air conditioning?

Regular servicing keeps your system running efficiently, maintains good air quality and extends its lifespan. It also helps keep running costs down and catches small issues before they turn into breakdowns.
