"Firstly, can I say thank you for all the time that you spent looking at the beam for the existing knock through and also trying to figure out how I could achieve what I wanted to in the house. Your efforts were above and beyond what I was expecting and I also appreciated your advice on other matters around the house. I will happily recommend your services to anyone I know looking for a structural engineer in London."
