Superb service and workmanship- 5 stars
I needed a new boiler and was recommended to GB Plumbing via Worcester Bosch as an accredited installer. The communication I had with GB Plumbing was first class. They surveyed the job and gave me a very prompt quote, which was competitive. They installed the boiler and took pride in their job. They put down carpet protection before the job. Everything was done as they said, and they were knowledgeable about the subject. I couldn't fault them in any aspect of the work. 5 stars!Verified reviewerJob location: E17
