CoolCosy LTD, are very pleased that you have made it to our web site and hope that you will choose us for work(s) in your home throughout Sussex and Surrey.

We check our Engineers, so you feel personally safe while we are with you. They are of course Gas Safe Registered, to work on Gas Competently.

Our aim is to provide the services you need, when you want them and at a price you can afford, we think of ourselves as a compassionate organisation who will always keep you our customers best interests at heart. We encourage individuals to install boilers with long warranties, parts and labour guarantees of 5 to 10 years, which can save you money. Unlike some big corporations who sell expensive annual maintenance contracts to homeowners.

Replacing old boilers with modern high efficiency design’s, will save energy and money. If your boiler is already fitted adjacent an outside wall this may not be as expensive as you think. Check the Energy Saving Trust website to see if you are eligible for a grant, and details regarding insulation.

From our website you can submit an online booking, see some of our fantastic fixed rate special offers and peruse our overview of services that we undertake.
