Dan came to quote for a new boiler. From start to finish, the experience was excellent. He came when he said he would to do the quote and emailed it over to me a couple of hours later. He was much cheaper than British Gas and provided a 10 year warranty whereas they offered 5. I would have no hesitation in recommending Dan. He is a friendly, efficient and tidy worker and we are very pleased with our new Baxi boiler.
