Dear Cousins Having just received your guarantee document in relation to our new conservatory we’d like to say that we are very pleased with it. It has exceeded our expectations. The construction is excellent, the finish really good. We’d particularly like to commend your teams, Ian and Louis, LJ and his crew for their excellent work. It’s (almost) been a pleasure having them here, despite them drinking us out of tea and coffee and elder-flower cordial. So many thanks to you all for a job very well done.
Dear Cousins Thank you all for the lovely flowers which arrived last week. As I was unwell at the time it was great to have the flowers to cheer me up. We are pleased with the finished conservatory and are settling into using it. Thank you for speeding up the laying of the floor.
Dear Cousins We would like to thank Gavin, Jackie the builders John and Chris the installers Dave and Richard for installing a beautiful conservatory. Everyone was so friendly and kind and kept us up to date of what was going on, I would certainly recommend cousins conservatories to my family and friends. Once again many thanks.
Dear Jackie, Gavin & all the Cousins team, Thank you all so much for our beautiful conservatory, it has made such a difference to all our lives, especially over Chrsitmas. Thank you for the beautiful flowers they looked lovely in our conservatory.
Dear Jackie & Gavin, We have been so busy enjoying the conservatory that I haven’t even got round to thanking you for building it. Its excellent – your men were great and all in all we are delighted with it. Getting it done with Cousins was a good move! We’re happy to tell others this too.
Dear Jackie & Gavin, We would just like to say how lovely our conservatory is that you have just built for us and how helpful from the start Jackie and Gavin have been. We would like to also thank Darren and Ian for their hard work especially during the bad weather. We are so happy with our lovely conservatory and be very happy to recommend your company.

Hi Sean, Just to thank you for organising the shed, we are very pleased with it and the guys putting it up yesterday were great too.
Dear Sean, I just wanted to take a moment to let you and Matt know how pleased we are with the summer house. Its exactly what we wanted and you were both so helpful with choosing the right product, right through to finishing the installation. A great service start to finish and that’s so rare these days, well done.
Dear Gavin and Jackie, Just a short note to say a big THANK YOU to you for our lovely windows and conservatory we are so very pleased. Also to your band of workers who we found to be very good at what they do. I cannot believe that everything is done.
