Alarm design for Bromley properties
Bromley runs from suburban streets around Penge and Beckenham to Green Belt villages beyond Orpington. Interwar semis and detached houses make up much of Petts Wood, Hayes and West Wickham, Chislehurst and Bickley have large houses on generous plots, and the town centres have growing numbers of flats. Long drives, outbuildings and gardens backing onto woodland all change how a burglar alarm is designed.
Large houses in Chislehurst, Bickley and Keston
Wide plots, several reception rooms and outbuildings mean a bigger system and careful radio planning. We put door contacts on every external door, motion detectors in each ground-floor room and shock sensors on accessible windows, then add range extenders to reach garages, annexes and pool houses at the far end of the garden.
- Separate areas for annexes and garages
- Outdoor detectors can watch the drive or rear garden
- Shock sensors on ground-floor windows for earlier warning
1930s houses in Petts Wood, Hayes and West Wickham
Many of these homes have been extended to the rear and into the loft, and plenty have a garage or side passage. A wireless system covers the ground floor, every external door and any upstairs room above a flat roof, without disturbing finished decoration. Most are fitted in a single day.
Period houses and conversions in Beckenham, Shortlands and Penge
Larger Victorian houses here are often split into flats, while others remain family homes with cellars and tall sash windows. Whole houses get room-by-room cover with shock sensors on accessible sashes; flats get compact wireless kits, and anything external is agreed with the freeholder first.
- Cellar and basement doors included in the design
- Sash windows protected with contacts or shock sensors
- External siren only with the freeholder's agreement in converted flats
Semi-rural homes towards Biggin Hill, Downe and Cudham
Isolated houses with stables, workshops or barns need their outbuildings covered, and owners usually want alerts on their phone wherever they are, with professional monitoring as an option. If the property is being renovated, we install a wired system at first fix, before plastering, and complete it at second fix.
Bromley has many conservation areas, including much of Chislehurst and parts of Beckenham and Petts Wood, so if your home is in one, or is listed, check with the council before fixing a siren to the front of the building.

FAQs
Burglar alarms in Bromley: your questions answered
Our Chislehurst house sits in a big garden. Will wireless detectors reach the garage and summer house?
Usually, with planning. Ajax devices have a long radio range, but walls, glazing and distance all reduce it, so signal strength is tested at each outbuilding during the survey. Where it is marginal, a range extender bridges the gap. Each outbuilding can then be armed on its own, separately from the house.
Is a wired alarm better for a 1930s house in Petts Wood?
Only if you are renovating. In a finished home, a wireless system avoids lifting floorboards and chasing walls and is normally fitted in a day. If you are about to replaster or rewire, a wired system is a good choice: cables go in at first fix, and the detectors and panel follow at second fix.
We keep horses at a property near Biggin Hill. Can the alarm protect the stables and tack room?
Yes. The tack room door can carry a contact and the room a detector, set as its own area so it stays armed while the house is in use. Outdoor motion detection can watch a driveway, though livestock and wildlife need careful positioning to avoid nuisance alerts. We walk the site with you to plan it.
Can you take over the alarm that came with the Beckenham house we just bought?
In most cases. We test the existing wiring and detectors, then replace the panel and keypad so you have your own codes, full control and app alerts. If the previous installer locked the panel, replacing it is normally quicker than waiting for access. Sound detectors are kept, which keeps disruption down.
How much does a burglar alarm cost in Bromley?
A wireless Ajax alarm starts from £995 including VAT, a wired or hybrid system from £1,995 including VAT, and upgrading an old panel while keeping your existing wired sensors from £495 + VAT. Your exact price depends on the number of doors, windows and rooms, and is fixed in writing after a free survey.
Wired or wireless — which is right for my home?
If your home is finished and lived in, wireless is usually best: no chasing walls, no redecorating, and most homes are done in a day. If you are renovating, a wired system run at first fix before plastering is the better long-term choice, installed at second fix once decorating is done.
Can you take over or upgrade my existing alarm?
Usually, yes — including systems we did not install. Where the existing wiring and detectors prove sound we keep them and replace the panel and keypad, which costs far less than a new system and can add smartphone control.
What guarantee do I get?
A 12-month guarantee on our installation work, alongside the manufacturer's warranty on the equipment we supply. You also receive a completion certificate for your records.
