Security planned around your actual risks

A security system needs to suit the way you use your property, not force you into a standard package. We protect flats, houses, shops, offices, warehouses and larger sites using carefully selected alarms, CCTV, entry systems, monitoring and smoke screens.
We begin with a free survey, listen to your concerns and identify vulnerable areas. You then receive a clear design based on the property, your budget and the level of response you need.

Richard came round this morning, on time and very positive.
He not only dismantled my alarm system, he also explained that there was no spare part for my old system and he took the whole thing away. We discussed getting a new alarm and I will most definitely come to your company to get a new one when I decide to get it. Richard was exceptional in every way: polite, very professional, very helpful and very kind. He is a credit to your company.
Yours sincerely

One team throughout the system's working life

You can use us for much more than the initial installation. We supply and fit new equipment, take over existing systems, replace outdated panels and provide planned servicing. If an urgent fault leaves your property without protection, our technical support and emergency call-outs remain available around the clock. As an independent company, we can select suitable equipment from several established manufacturers rather than limiting your system to one brand.

Clear reasons to place your security with us

Accredited standards

We hold SSAIB approval and ISO 9001:2015 accreditation for accountable work.

Independent advice

We compare established equipment brands against your site, needs and budget.

Continued support

We maintain, diagnose and upgrade your system after installation.
