Plumber

Norbert was the first to call and scheduled me in towards the end of a Saturday afternoon. Job done efficiently. There was another issue which needed help with while he was here, he didn't charge me extra and only invoiced me for what was discussed. I decided to pay something extra, not a great deal but felt Norbert deserved it and is just my appreciation. will definitely recommend and will defintely reach out again.

Norbert has done an excellent job. He balanced the radiators, checked the pump, and explained how I could adjust the hot water and heating more efficiently. He advised me on what could be done in the long run to keep the system healthy. He also sealed a leaking lead pipe in a very awkward position. All the plumbing problems in the house were sorted in one go.

We cannot recommend Cosy & Safe highly enough. Norbert came over within a few hours of us calling him to fix our boiler and carry out a safety inspection. He is very personable, professional and knowledgeable and went above and beyond to make sure that the problem was rectified. Our boiler is working far better than it has for years and we are so pleased to have found a great plumber. We would not hesitate to use him again and have already recommended him to family and friends.

He was recommended to me by a friend who had used his company for extensive boiler and plumbing works. I have used him regularly since for servicing the boilers , getting the right certificates ,fixing the boiler when it broke, fitting new toilets. I highly recommend Norbert. He answers calls promptly, makes appointments and arrives on time and if it can be fixed he will fix it. .
