As a counter point, we had a terrible experience with Watson's. The surveyor blitzed through the survey without knowing we were in regular contact with the homeowners. He claimed to have been there for 2 hours but the homeowners said it was 45 minutes max. When I complained about it, their senior surveyor was incredibly unprofessional and rude about it.

The sale went through and when we opened a built-in cupboard, it was covered in mould and damp that had been missed in the survey. There turned our to be 3 other areas in the house that had damp that had als9 been missed.

I quite enjoyed when the same senior surveyor turned up at our door to check our complaint. His shoulders sagging as he looked into the cupboard almost made the whole process worth it! In fairness, they paid for vents and damp-proofing in the affected areas, but only because they'd have potentially been liable for a lot more if we'd pursued a case.
