Business Information

My name is John Mullan and I'm a retired fire officer with 30 years' service and an additional 16 years as a Building and Facilities Manager in Glasgow's City Park.

I import, sell and fit interlinked smoke and fire detectors conforming to Scottish Government regulations introduced in February 2022 and now required in all homes by law. Insurance companies also invariably have a clause in the policy to the effect that the property complies with Building Regulations, within which the new regulations are included.

These radio frequency alarms are installed at very reasonable prices, typically £140 to £175, without mess or the need for expensive electrical work, and usually within a day or two of ordering. I'm happy to give an estimate on the phone and can take calls between 9.00am and 9.00pm.

Please see my reviews. I have never had a customer who was dissatisfied with my work or prices, and regularly receive referrals from them for friends and neighbours.

From the point I made contact with John to completion of works, I found him to be courteous, professional and extremely knowledgeable, his workmanship was very tidy and quickly carried out, enabling me to arrange a home report for the sale of my property. I would highly recommend John to other customers.

Excellent work from John for a second time. Reliable, efficient and a very nice manner. Great advice given on fire safety issues from a former serving fire officer. No hesitation in recommending him to others.
