Fire Alarms and Fire Safety


A reliable and fully vigilant fire alarm and warning system is a necessity to protect occupants of a building – be they workers, residents, students, patients, customers, or whoever works in or visits the building.

We design, install, maintain, and regularly check fire warning systems to ensure that nothing is left to chance. All our installations are tested to the highest of British Standards and we can also repair, refurbish, and upgrade existing systems to attain the highest standards of vigilance and safety.

Electrical Testing


Munns Group can carry out a complete range of testing for electrical appliances, from individual items to complete installations.

Munns Group have been undertaking systematic Portable Appliance Testing (PAT) on a wide variety of sites for many years which is now an integral part of an organisation’s Health and Safety policy and procedures. This has varied from testing all appliances at 78 schools in one London Borough within six weeks, to testing the domestic and sheltered accommodation for housing associations.

Data Installation


Imagine if your computer systems went down right now. How much data, time, and money would you lose as a result?

All organisations rely more and more on their computer systems and networks to process the information and data that is their lifeblood. In turn, computer hardware and software systems – to be 100% effective – rely on the design and installation of data cabling, backup systems, and layout of work stations. This is where the experience of Munns Group is so critical in ensuring the maximum benefit is gained from an installation so that your computer systems remain stable and effective for as long as possible.
