PLEASE PLEASE DO NOT USE THIS COMPANY. As soon as you have paid them their money the service is appalling! I had a new combi fitted on 17th November and they are stil trying to remedy the mess and problems that they made when they installed the boiler at my property. They never ring you back I am still awaiting my welcome pack and my guarantee for the boiler. I have emailed them with photos of everything I am not happy with and they have sent someone out three times to sort problems including replacing floor board where the installation engineer botched and broke when fitting the pipes. The work carried out to repair the floorboard is very poor. The whole experience has been very stressful. It has put back weeks our move into our property and cost a lot of money because of the delay. They are not at all professional and you have to chase them constantly!
