Report
After 9 years of enjoying our excellent Cousins built conservatory we had to call for help with a roof panel. Dave was with us within two hours and fixed the problem at no charge. We have always experienced excellent service from the team, but this really was most impressive. Thoroughly recommend Cousins for build, maintenance and after care.

Had a garden shed with concrete base installed in my garden. Took 6 weeks from ordereing to installation as told when purchased. Both the base builder and shed erectors did a very professionan job. Very pleased with the shed and service from Cousins.

Report
After looking for an ex display office for several months, I finally found one at Cousins Conservatories. From start to finish, the customer service was second to none, and they even allowed me to put a deposit down until my house move went through. They arranged for the base to be laid, and the company they used were first class professionals who even turned up the day of Storm Eunice. The office was finished yesterday, and again it was fitted by an extremely competent company who provided a first class service and nothing was too much trouble. They also gave good advice on the upkeep of the office. I would have no hesitation in using Cousins Conservatories again.
