SW18 Scenarios

Six common reasons Wandsworth books us

Pre-booked work covers planned lock change and upgrade work only. These are the situations we get called for most often in SW18.

New Move-In

Just bought a Wandsworth home

Completion day or shortly after — replace every external lock and key set so the previous owner, their agents, and any contractors can't return. Most-booked reason in SW18.

HMO Compliance

Landlord HMO inspection due

Wandsworth Council HMO licensing requires BS3621 fits on each let-room door and a kitemark front door lock. We supply the receipt and pre-tick the inspection sheet.

Tenant Turnover

New tenant moving in soon

Fresh cylinder set between tenancies. We swap the cylinder only (cheaper than full lock change) and supply two cut keys for the deposit pack.

Lost Spares

Lost spare keys to a flat or back door

Spares left with a builder, lost in a move, or never returned by a previous owner. Cheaper to swap the cylinder than worry about who has them. Same-day appointment.

Insurance Upgrade

Renewal flagged your locks

Insurer renewal mentions BS3621 or kitemark. We replace the front door mortice with a 5-lever Union or Yale BS3621 and provide a written receipt naming the lock for your policy file.

Brand of Choice

Want a specific brand fitted

Ultion, Avocet ABS, Yale Platinum, ERA Vectis — tell us when you book. We bring exactly that brand from stock; no "this is what was on the van" substitutions.

Why Pre-Book

Plan it once. Fit it right.

Local Knowledge · SW18

Lock changes across SW18 — from Wandsworth Common to the Riverside

Wandsworth runs a mix few SW postcodes match — Victorian terraces around the Magdalen and Heathfield conservation areas, period flats by King George's Park, and riverside new-builds along Wandsworth Bridge Road. Each one needs a different spec: original timber doors take a 5-lever BS3621 mortice + deadlocking night latch combo, while the riverside flats usually run multipoint Euro cylinders that need anti-snap upgrades after developer handover.

We're a five-minute drive from Wandsworth Town station and routinely book same-week appointments for landlords managing HMO portfolios across Earlsfield, Southfields, and Tooting. Conservation-area front doors need particular care — we work to keep the original brass furniture and upgrade the internal mechanism without changing the visible hardware.

Frequently Asked

Lock change questions from Wandsworth

Six things SW18 homeowners and landlords ask before booking. Anything else, send us a WhatsApp.

How quickly can you book me in for a lock change in Wandsworth?
Most pre-booked appointments are same-day or next-day. WhatsApp a photo of your current lock and we'll confirm a slot — morning, afternoon, or weekend — usually within an hour.
Do you charge a callout fee for pre-booked work?
No. Pre-booked appointments are quoted in writing before we visit. The price you see is the price you pay — card or cash accepted on the day.
What lock brands do you fit in SW18?
ERA, Union, Yale, Avocet ABS, Ultion, and any UK kitemark cylinder. Tell us when you book and we'll bring exactly that brand — no substitutes.
Will my home insurance recognise the new lock?
Yes. For front doors we fit BS3621 5-lever mortices (kitemark) and TS007 3-star anti-snap cylinders, with Sold Secure Diamond options for the highest insurance ratings. Both meet the lock specification clauses in standard UK home insurance-approved door lock requirements. Written receipt naming the lock provided on request.
I live in a Wandsworth conservation area — can I upgrade the lock without changing visible door furniture?
Yes. We do a lot of conservation-area work around Magdalen and Heathfield. We replace the internal mortice mechanism while keeping the original brass escutcheon, knob, and letterplate. Council consent isn't usually needed for internal-faced upgrades.
Do you fit key safes in SW18 — and where can I legally put one?
Yes — WhatsApp for current pricing — fitted, brick-mounted with masonry anchors. For most Wandsworth properties it's straightforward. For Wandsworth Riverside Quarter and similar managed developments, check your lease before placing one on shared brickwork — we can advise on discreet positions that satisfy management companies. See our key safe installation page for full details.
Wandsworth Homeowner Guide

Three things every SW18 homeowner should know

Quick, useful, and based on what we see across hundreds of Wandsworth front doors.

01

Period doors aren't built for modern cylinders

Victorian and Edwardian timber doors around Magdalen Rd or Heathfield often run shallow mortice cases. Forcing a modern Euro cylinder splits the rail. We measure the case before quoting.

02

BS3621 is what your insurer actually wants

Most home insurance policies in SW18 reference "British Standard locks (BS3621)" by name. A 5-lever mortice with the kitemark stamp on the faceplate satisfies the clause — anything else risks a denied claim.

03

Anti-snap is non-negotiable on Euro cylinders

If your front door runs a Euro cylinder (most SW18 uPVC and composite doors do), it must be TS007 3-star or Sold Secure Diamond. Lock snapping accounts for the majority of London opportunist break-ins.
