What Our Customers Say

Real reviews from real customers across South Wales and the South West.

I couldn't praise C&T Group enough, from the time I contacted them regarding my mum's faulty combi boiler, to the date my mum's new boiler was fitted it was 1 month. Everyone I spoke to was friendly and helpful. When Neil and Ben came to fit the boiler, they were quick, efficient, friendly and very thoughtful and thorough and left everything spotless when they left. I used the same company myself in 2024 and had the same fantastic service, I have recommended them to friends and family since and will continue to do so. Thank you to all involved, from start to finish.

A. Reece

C&T handled our cavity wall insulation and loft top-up. The survey felt detailed and not rushed. The installers respected our home and cleaned up afterwards. Straightforward service and good communication throughout.

B. Cook

We had a new boiler installed under a grant scheme. The team explained the process clearly and kept us updated at every stage. The engineers were polite and efficient. Everything was completed to a high standard. Would recommend.

C. Silva

From first contact to installation, C&T Group were organised and professional. The survey was thorough and clearly explained. The install team arrived on time, worked cleanly and left the property tidy. Communication throughout was excellent. Very happy with the service.

A. Powell

Boiler wasn't providing any heating to the house (old and broken down) and although we were not on the priority register, we now have been and still within a week of comms with C&T our new boiler is installed and is better than our last one. Neil Jones did a fantastic job! It was friendly and professional the whole way through. He discovered we had problems with our gas pressure and called Wales & West to come over that evening and sort that out for us. This meant Neil had to come back the next day to finish (and we're all the way in Bristol!) and again, friendly, professional, and has done a fab installation of the boiler including extra pipe work too. Zero complaints 😁

D. Collins

We were very pleased with C&T Group all communication was excellent. They were very helpful and always ready to answer questions. We had central heating loft insulation and ventilation. The men who came to complete the work were superb quick efficient friendly and cleared up everything afterwards. Would highly recommend.

B. Burton

I am delighted with my new boiler and wish to thank all staff at C&T Group for all their work resulting in me securing a new, smart looking and efficient boiler for my special, forever home. From survey to installation, the work carried out was professional and at all times, my home was treated with respect. I have every confidence in this company and highly recommend them to anyone wishing to make their home Eco friendly and efficient.

C. Pugh

Quick to respond to my initial enquiry, though the whole process took longer than I thought it would. The solar and the air source heat pump was installed with no cost to me whatsoever, and all the tradesmen were professional, clean and tidy. 5 stars no questions.
