I booked a survey with Flettons in March 2020 and because of the Covid-19 situation it had to be cancelled. They refunded the money as soon as I asked. When I re-booked they attended the house within a week and sent a summary of their findings the day after. The full report arrived only a few days later and it was very thorough and useful. Simon was very helpful and even took the time to answer some questions over the phone and send some additional photos of the property not included in the report.
I would definitely use them if I ever buy a house again!
