Dennis has done a superb job of installing our new boiler, which was fitted within two weeks of him first coming to look at the job. He is very nice and friendly, reliable and very personable. He obviously takes a great deal of pride in his work. We are extremely impressed with his workmanship which is very neat and tidy. He didn't leave any mess and always tidied up before he left. We would have no hesitation at all in recommending him and would definitely ask him to do other jobs for us when needed.
