Tom did a fantastic job and was extremely reliable and professional. He gave really good advice to fit my needs precisely, and the installation was completed in exactly the time promised. He went above and beyond to do the job right and make it look good.

Used Wilsair for a gas heating service (with certificate). We required the work as part of a house sale agreement and Wilsair were far beyond competitors in regards to communication and availability. My emails were replied to same day and the work was planned in around other commitments to ensure I had the work completed ASAP. Certificate and photographs were provided on the day and even emailed for ease of forwarding to our solicitor. Very positive experience all round and will be using again.

Tom did the work for us having been struggling with other trades to find a solution. In the end he did a lot of research and phone calls to decide what boiler and style of installation was going to best for us in terms of reliability and convenience and speed. He located the right boiler and fitted it and we are very happy with what he has done. Not only that but since then he has made a point of checking that everything is working correctly. We are very happy with the level and quality of work that we received.

We have used Wilsair to maintain our air conditioning for the last 3 years. They always explain what needs doing and any costs involved before carrying out chargeable work.
Reliable, knowledgeable and I would have no hesitation in recommending them.
