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 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 contract to the effect that the property complies with Building Regulations.

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.

John was very prompt in answering our request to fit our new smoke alarms. When he arrived he explained everything fully to my husband and me. John was a delight to have in our home and I would recommend him to anyone that is needing this done. He is also very reasonably priced. Thank you.

New smoke and carbon monoxide alarms installed.
I'm so grateful that Mr Mullen was able to provide the service I needed on the day of it being requested.
Apart from explaining what was needed and how the alarms worked, Mr Mullen was very polite and patient in the conversations we had. He worked quietly and efficiently.
Thank you so much.

John fitted a full set of smoke alarms as my current ones had failing batteries. He responded to my enquiry quickly with very reasonable prices and was super easy to deal with throughout. He did the job with no fuss and took all rubbish away with him. Couldn’t ask for more - highly recommended!
