May we take this opportunity of thanking you for the excellent service received from your company and every aspect of this re-fit.
Thank you very much for the splendid job your firm has carried out of installing central heating in our bungalow.
Both your engineers were excellent, good humoured and have done a first class job. They gave me a full explanation of what they were going to do and were also very polite.
I am writing to say thank you for the efficient service I recently received from Gas Connect. From the beginning, when I was given a quote for work needed and advice from you, to the completion of works, everyone has been very professional in attitude and service.
