Local context — Wandsworth
Wandsworth records one of the lower burglary rates in inner London, but recent Metropolitan Police data shows residential burglary still affects roughly one in 80 households per year. Visible CCTV and monitored intruder alarms remain the single most effective deterrents in the borough.
Fire alarm work we actually do in Wandsworth (SW11, SW17 & SW18)
Wandsworth is our home borough — Security House sits on Summerstown SW17, on the Garratt Lane corridor between Earlsfield and Tooting — so most of our fire alarm work here is within a ten-minute drive of the office. The housing stock decides the system. Earlsfield and the grid streets off Garratt Lane are Victorian terraces and flat conversions where interlinked Grade D1/D2 detection under BS 5839-6 is the standard fit: wireless heads in escape routes, heat detection in kitchens, no chased cabling through original plaster. A typical Grade D interlinked install runs £200–£500 per dwelling, certificated for your insurer on completion.
Tooting and the streets around St George's Hospital have one of the densest concentrations of HMOs and converted flats in south London. Where a property is licensed as an HMO, licence conditions consistently require interlinked detection with LD2 coverage — smoke detection in escape routes and high-risk rooms, heat detection in kitchens — and Wandsworth HMO Grade D LD2 systems are from £600 installed depending on storeys and layout. We install, certificate and, where the licence requires it, service the system annually so the paperwork is ready at inspection.
Commercial work concentrates in three places: the hospitality and retail strip along Tooting High Street and Mitcham Road, the light-industrial units and railway-arch businesses around Earlsfield and Summerstown, and the office and riverside developments at Wandsworth Town. These premises need a BS 5839-1 system matched to the fire risk assessment — usually Category L2 or L3 where there is sleeping risk above the unit, which is the norm for shops with flats over. Addressable panels start from around £1,200 installed, and because the office is in the borough we can usually attend a panel fault in SW11, SW17 or SW18 the same day.

Are your fire alarm installations certificated?
Yes. Every fire alarm installation is carried out to BS 5839 and we issue a compliance certificates with every installation for insurers, landlords and letting agents.
Do you cover Earlsfield and Tooting for fire alarm installation?
Yes — our head office is on Summerstown SW17, between Earlsfield and Tooting, so both are core coverage.

What fire alarm system does a Wandsworth HMO need?
If your property is a licensed HMO, the licence conditions will normally require interlinked fire detection with LD2 coverage under BS 5839-6 — smoke detection in escape routes and high-risk rooms, with heat detection in kitchens. We install to that standard and issue the certificate the council and your insurer expect, with systems from £600 installed and certificated.
