Alarm design for Brent properties
The south of Brent is older and denser: Victorian and Edwardian terraces in Kilburn, Queen's Park, Willesden and Harlesden, many divided into flats. Further north, Kingsbury, Preston, Sudbury and Wembley are dominated by 1930s semis and detached houses, while Wembley Park and Alperton have added large numbers of new flats. Whether you own a whole house or one floor of one decides the design.
Converted flats in Kilburn, Queen's Park and Willesden
A converted Victorian house might have a ground-floor flat with a garden, a basement flat with its own entrance, or an upper maisonette reached by a shared stair. We cover your own front door and any rear or garden doors, add motion detection inside, and keep everything within your flat unless the freeholder agrees otherwise.
- Garden flats: rear doors and windows treated as the main risk
- Upper flats: protection focused on the entrance and any roof access
- No external siren without the freeholder's written agreement
1930s semis and detached houses in Kingsbury, Preston and Sudbury
Extended semis with large rear kitchens and loft conversions are common. Every external door gets a contact and every ground-floor room a motion detector; if a bedroom window sits above the flat roof of a rear extension, that room is covered too. Wireless Ajax kit means no redecorating afterwards.
New apartments at Wembley Park and Alperton
Modern blocks often have controlled entry at street level, so protection inside the flat is about the front door, balcony doors and the main living space. A small wireless alarm sends alerts to your phone and can be taken down and moved if you sell or your tenancy ends.
- Entrance and balcony doors on contacts
- Indoor siren paired with phone alerts
- Removable kit that suits renters and shorter leases
Shops on Harlesden and Kilburn high streets and units around Park Royal
Retail premises need cover on shutters, rear yards and stockrooms, and businesses often want individual staff codes so they can see who opened and closed. We design for the building and the trading hours, with separate areas for offices or storage that need to stay armed during the day.
Parts of Brent, including Queen's Park and Mapesbury, are conservation areas, and some have Article 4 directions restricting changes to front elevations, so it is worth checking with the council before an external siren goes on the front of a house.

FAQs
Burglar alarms in Brent: your questions answered
I own a ground-floor flat in Queen's Park with a garden. What should the alarm cover?
The garden side is usually the priority. We put contacts on the front and rear doors, motion detectors in the main rooms, and shock sensors on garden-facing windows if you want earlier warning. If the lease restricts what goes on the outside wall, the siren stays inside and alerts go straight to your phone.
My Kingsbury house has a loft conversion and a rear extension. Is the upstairs covered?
Rooms are covered if they can be reached. A loft room is rarely an entry point, but a first-floor bedroom above a flat-roofed extension often is, so we add a detector or window contact there. The landing can also carry a detector to catch anyone moving between floors.
Can I fit an alarm in a rented flat in Wembley Park?
Usually, with your landlord's agreement. A wireless alarm is held on with a few small fixings, needs no cabling and can be taken down when you leave. External equipment needs the managing agent's permission as well. We are happy to provide the details your landlord needs before the survey.
My shop in Harlesden has an old alarm that keeps going off for no reason. Can it be fixed?
We start by testing what is there. False alarms are often caused by tired detectors, poor positioning or failing batteries rather than the whole system. If the wiring is sound, we can replace the panel and keypad, swap faulty detectors and add an app so you can see exactly which zone triggered and when.
How much does a burglar alarm cost in Brent?
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.
