"Dear Andy (if I may!)
Just to say thank you so much for looking after me throughout my entire move. Every member of your staff with which I had dealings was polite, friendly and helpful (no particular order just all three at No. 1!). The time and trouble you personally took with my move back North really is appreciated.
I think I had already decided I wanted Appleyards to have my business - because I remembered how helpful and fair you were when giving me a quote nearly 5 years ago.
I was not wrong because it made one part of the 'Moving House' process absolutely stress free. I must give a special thank you to Mark and his colleagues for their efficiency and of course, the laughs!
