Missing evidence lowers the score because we can't check it. It doesn't mean it doesn't exist. Claiming a profile never changes the score. Evidence context, not a guarantee of workmanship.

Nige was very friendly, helpful and professional. He arrived at the time booked and explained clearly what he was going to do. He thoroughly tested the Emergency Lighting and identified a fault which will be rectified the following week. I learnt alot about many aspects of fire safety from asking him questions which is so useful going forward. I was very pleased to get a Fire Safety Log book for our flats. I thought I would have to produce my own so that was fantastic. Very pleased with all aspects of the visit. Thank you Nige. I can thoroughly recommend Holt Alarms!
