Critical:Professionalism, Responsiveness I've been waiting over 2 months for a quote. Have constantly chased them and keep getting told will get back to you. Absolutely shocking company and appalling customer service.

We have had a new boiler fitted by Plumb-Line. It was an efficient and friendly service from start to finish and we would not hesitate to employ them again and recommend them highly to other potential customers.

Two young and very efficient men worked very hard for two days and did a very satisfactory and tidy job for us. We would recommend them to anyone and they left the place spotless. Their office support staff were excellent too and they rescued us from a desperate start point.

All the team from the survey to the installation of our new boiler. Were most helpful, expert and professional, very tidy and neat and much improved the existing pipework. Work was completed on time and within agreed budget.

Last month, my warm air system gave up the ghost and had to be replaced and it was suggested that I contacted Mark Brown of Plumb-Line. Couldn't have asked for more, the system was replaced and working within 24 hours. After installation you wouldn't have known that a major project had just taken place as the site was left spotlessly clean. Great people to deal with and I would have no problem recommending this company to anyone looking to use their services.

We had an old water system removed and a full central heating installed (10 radiators and boiler). We were able to discuss our requirements with Adrian, who offered choices for radiator and boiler types to best meet our needs. We never felt rushed or pressured into making decisions or commitments. From our 1st contact with Plumb-Line , everyone was very friendly, knowledgeable, with no hard sell.

The service was prompt , clean, very tidy and highly professional. We would highly recommend Adrian and his team for any plumbing or heating job. Our experience with Plumb-line far exceeded all work that we have had done over many years with other companies. We will definitely be sticking with and recommending Plumb-line for all future work. Thank you to Adrian, Spense and Bradley.

Initial contact with Plumb-Line, from the office through to the team who came out to my home, were nothing but attentive, professional and always reassuring. Extremely tidy, polite and a pleasure to deal with. I will recommend and continue to use Plumb-Line for all my plumbing needs.

Arrived on time, workmanship was of a very high standard. Explained clearly how upgraded system works. Left our house clean and tidy. System appears to be working correctly. Paperwork was thorough too and good communication from the company.
