Alarm design for Lambeth properties
A large share of Lambeth's homes are flats, whether in converted Victorian houses, purpose-built mansion blocks, council estates or the newer towers around Vauxhall. The family houses that remain, especially in Clapham, Herne Hill, Streatham and West Norwood, often have rear extensions and long gardens. Whether you own the front door or share it shapes the whole design.
Converted Victorian houses in Brixton, Stockwell and Clapham
Upper and garden flats in split houses each need their own system. Garden flats usually have a rear door or French doors out of sight, so they get contacts and motion cover there as well as at the front. Upper flats focus on the entrance door and any window reachable from a back addition roof.
- Garden flat patio doors protected as a priority
- Windows above back additions included in upper flats
- Internal siren only unless the freeholder agrees to an external one
Edwardian houses in Clapham, Herne Hill and Streatham Hill
Bay-fronted family homes often have a side return extension with rooflights, a rear garden door and sometimes a loft conversion. A wireless alarm fitted in a day covers every external door and ground-floor room, with shock sensors on wide glazing and pet-tolerant detectors for households with dogs or cats.
- Side return glazing fitted with shock sensors
- Every ground-floor room covered by motion detection
- Pet-tolerant detectors chosen to suit the size of your pet
Georgian terraces in Kennington and around Vauxhall
Older terraces near Kennington Park and the Oval often have a basement and front area steps. The lower floor and its area door get contacts and motion cover, and accessible sash windows can have shock sensors. Wireless devices protect original features and avoid chasing walls in listed or sensitive houses.
New apartments in Vauxhall, Waterloo and Streatham
High-rise and mid-rise developments usually have a concierge and controlled entry, so a flat alarm concentrates on your own door and living space. A compact wireless kit with a door contact, one or two detectors and an internal siren is typical, with alerts sent to your phone when you are away.
Lambeth has many conservation areas, including much of Kennington, Clapham and Brixton, and listed building consent may be needed before a device is fixed to the outside of a listed house.

FAQs
Burglar alarms in Lambeth: your questions answered
How do you protect a garden flat in a Brixton or Stockwell conversion?
Garden flats tend to have two entrances: the front door off the shared hall and a rear door or French doors to the garden. Both get contacts, and the rooms nearest the garden get motion detection. Shock sensors on the rear glazing give an early warning. Everything is wireless, so no shared walls or communal areas are disturbed.
Is a wireless alarm suitable for a large Clapham house with a loft conversion?
Yes. Wireless devices reach several floors, and a repeater can be added if walls are thick or the house is deep. The ground floor and any rooms above a flat roof are protected, while bedrooms in the loft and first floor can be left out of the night setting so you can move around freely.
I live in a Vauxhall tower with a concierge. Do I still need an alarm?
Concierge and entry control protect the building, not your individual flat. A compact alarm covering your front door and living areas tells you on your phone the moment the door opens while you are away. It is small, wireless and fixed only inside your flat, so there is nothing for the building management to approve externally.
Can an alarm be fitted while we extend our Herne Hill house?
If the extension is part of a bigger refurbishment, a wired system can be installed in two stages: cables run at first fix while the walls are open, then the panel and detectors installed at second fix after decoration. If only the extension is changing and the rest of the house is finished, a wireless system fitted after the build is usually simpler.
How much does a burglar alarm cost in Lambeth?
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.
