I had a full structural survey done by Simon from Flettons. Well worth the money! The detail of the survey and the layout was most helpful to inform my purchase of a rather neglected 1930s mid terrace. Turn around time was fast as well. Not only that but about 1 year later I called up Simon to ask for further advice with regards to renovation/extension/conversion works that I had planned and he was most helpful and recommended good websites and books I should read in prepatation. Would definitely recommend to anyone needing a survey done!
