Matt was prompt, thorough and efficient in the service and certifications of our fire extinguishers. Some great background information on our installation requirements that could result in future savings.

We've been with MH Fire & Security for nearly a year now, and Matt has consistently delivered on his service promise. His communication is fantastic, and he always responds quickly to my queries. If you're thinking of going with this company, do it!

Fantastic service from Matt yet again! Always happy to help, going over and above to make sure our home stays safe. We first contacted Matt having issues with an install by a previous provider. Matt was quick to put the issues right whilst spotting other ways we could secure our home.

From the initial contact right through to post installation support, MH have been nothing short of superb. From the initial discussions of what we wanted, Matt assisted us every step of the way, explaining the products, how they would benefit us an leading us toward the perfect CCTV, alarm and doorbell system. Matt arrived when he said he would and carried out the installation to perfection - with a smile on his face too! Matt took pride in his work, cleaned up after himself and ensured we knew how to operate everything before he left. Our neighbours and family have secured MH's services after seeing the quality of our install. Matt and MH Fire & Security are an absolute pleasure to deal with and I can wholeheartedly vouch for and recommend them. Thank you very much Matt.

Best in the business, Iv dealt with various cctv & alarm companies over the years and MH fire & security have been the best by a country mile! Amazing communication, gets the job done to the highest standard with care for the aesthetic you want to achieve. Zero pushy sale tactics and completely honest advice in providing what's best for your needs. A really refreshing and honest approach to how they conduct their business! Couldn't recommend enough!
