Alarm design for Sutton properties
Most Sutton homes are suburban houses with front drives, side gates, garages and long gardens, so the rear and sides matter as much as the front door. Bungalows put every room on the ground floor. Older village centres in Carshalton and Cheam add period properties, and the town centre has more flats each year. The alarm plan changes with each of these.
Semis in North Cheam, Worcester Park and Carshalton Beeches
These homes typically have a hallway, two reception rooms, a kitchen extension and a garage or side passage. We fit a contact on every external door, a motion detector in each downstairs room and cover any upstairs room reached from a flat roof. Wireless systems such as Ajax are usually fitted in a single day.
- Garage connecting doors and side doors included
- Upstairs cover above flat-roofed extensions
- Pet-tolerant detectors for homes with dogs or cats
Bungalows in Wallington, Beddington and Carshalton
With every bedroom on the ground floor, a bungalow needs a design that protects the house at night while you sleep. We arrange detection so living areas, the kitchen and external doors can be set while the bedroom corridor stays off. Shock sensors on bedroom windows give earlier warning without stopping you moving around.
Older houses around Carshalton village and Cheam village
Victorian and earlier houses near the Carshalton ponds and in Cheam often have cellars, outbuildings and original joinery. A wireless system protects them without chasing cables into old walls. If an older wired alarm is already fitted, we test it and, where the cabling is sound, keep the detectors and replace just the panel and keypad.
- Takeover of existing wired alarms where cabling tests sound
- Cellar and outbuilding doors covered
- No cable chasing in original plaster
Town-centre flats and units off Sutton High Street and Beddington Lane
Flats near Sutton and Wallington stations suit a compact wireless alarm kept inside the flat. Shops on the high street and units on the Beddington industrial estates need shutter contacts, stockroom cover and separate areas for office and warehouse, with alerts going to whoever holds the keys.
- Internal siren unless the managing agent agrees to an external one
- Shutter contacts and warehouse motion cover
- Separate setting for office and stock areas
Carshalton village and Cheam village are among Sutton's conservation areas, so siren boxes on front elevations there may need to be sited sensitively; we check this at survey.

FAQs
Burglar alarms in Sutton: your questions answered
We live in a bungalow in Wallington. Can the alarm be on while we are asleep?
Yes. We set up a night mode that arms the external doors, kitchen and living rooms while leaving the bedroom corridor and bathroom free. If anyone opens a protected door or enters a protected room, the siren sounds and your phone is alerted. You set it from the keypad, a keyfob or the app.
Can my alarm cover the detached garage at the side of my Cheam house?
Usually. A wireless door contact on the garage door and a detector inside can report back to the main panel, with a range extender if the signal needs help. The garage can be its own area, so you can leave it armed when the house is in use, or set the whole property at once.
Is it worth keeping the old wired alarm in our Worcester Park semi?
If the cables and detectors test well, keeping them saves disruption. We replace the ageing panel and keypad with a modern one from Texecom, Pyronix or Ajax that sends alerts to your phone. If the wiring is damaged or the detectors are failing, a wireless system is often the cleaner option.
We are extending our Carshalton house. Should we wait before installing an alarm?
If the work includes new walls and ceilings, it is worth running alarm cables at first fix, before plastering. The panel and detectors are then fitted at second fix. Alternatively, a wireless system can go in once the extension is finished, without any cables in the new rooms.
How much does a burglar alarm cost in Sutton?
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.
