> "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!"
