An intruder alarm adds a different type of protection from CCTV. Cameras help you monitor and review activity, while an alarm is designed to detect relevant events and raise an alert through the functions available on the chosen system. Used together or separately, the important point is that the equipment should match the layout and normal use of the property.
We install intruder alarm systems for homes and businesses around Leicester and Leicestershire. We look at likely access points, circulation areas, the way occupants use the building and any practical installation constraints before recommending detector locations and controls.

An alarm that is difficult to live with is more likely to be ignored, left unset or used inconsistently. We therefore consider routine use as part of the design. For a home, that can include how people enter and leave, whether pets are present and which parts of the property need protection at different times. For a business, considerations may include staff access, stock areas, out-of-hours protection and the number of people responsible for setting or unsetting the system. Detector selection and positioning depend on the property and chosen equipment, so we avoid treating every building as the same collection of rooms. We also explain the controls in plain language during handover so the people using the alarm understand the normal setting and unsetting process. Where CCTV or access control is already installed, we consider the alarm as part of the wider security picture rather than assuming one technology replaces another.
Domestic alarm systems can be planned around the entrances and internal areas most relevant to the home. We take everyday movement into account so the recommended layout is practical for the people who live there rather than simply maximising the number of devices.
Businesses may need protection across entrances, offices, stores, workshops or other areas that are unoccupied outside working hours. We look at how the site operates, who is responsible for the system and which areas warrant detection.
Detector locations should reflect the layout, potential movement through the property and environmental factors that can affect performance. We choose positions based on the actual site instead of relying on identical placement from one property to the next.
The alarm should be straightforward for authorised users to operate. We explain the relevant controls and normal procedures at handover so the system can become part of the property's routine rather than something occupants avoid using.
If an older alarm is difficult to use or has developed reliability problems, we can assess the existing installation and discuss whether targeted work or replacement is the more practical option.
| Service | Estimated Cost | Average |
|---|---|---|
| Small home alarm system | £450–£850 | Around £650 |
| Larger domestic alarm system | £700–£1,300 | Around £1,000 |
| Small commercial alarm | £900–£1,800 | Around £1,350 |
| Larger commercial system | £1,800+ | Survey required |
Alarm prices vary with property size, number and type of devices, controls, cabling and the functions required. These figures are indicative planning ranges only.

We consider how people enter, leave and move through the property so the alarm remains practical to use every day.
We recommend detection for relevant areas rather than adding devices without a clear reason.
Users are shown the everyday controls so setting and unsetting the alarm is easy to understand.
Where CCTV or access control is also involved, we can consider how the different layers of security complement one another.
