Security, both external and internal, plays a key role in
protecting your business. It’s a must to help reduce crime and

Thinking about installing the right alarms, CCTV, locks and
lighting is a vital part of any business plan.
Follow the steps below to make your building secure. You’ll find

Windows and doors
Windows and doors can be the most vulnerable part of your
premises, particularly those on the ground floor or at the back of
the building, so fit good quality locks.
Install windows certified to British Standard
BS7950 (windows of enhanced security) and doors that meet
Product Assessment Specification 024 or
LPS 1175 SR 1-6 grades.
Think about using laminated glass (a minimum of 6.4mm thick) in
windows and door glazing as it’s much harder to be break. If you
choose a wooden door, it should be more than 40mm thick.
You might also want to consider fitting shutters and grilles.
Safety bars on windows can deter thieves too but be careful not to
block emergency exits.
Blinds are a good idea, particularly on ground floor windows, as
they can stop thieves spotting expensive equipment. You should also

a clearly visible alarm so it’s advisable to fit one. Your
Reduction Officer, CCTV Liaison
Officer or companies registered with the National Security
Inspectorate or Security Systems and Alarm Inspection Board will be
able to advise what sort of alarm is best for you.
Always buy an alarm system that meets British or European
standards and contact a professional to install it – an alarm that
doesn’t work properly could end up costing your business more in
the long term.
If you’re planning a new factory, office complex, retail unit or
even just a refurbishment, it’s important to think about how the
design of a building can help reduce the likelihood of crime.
