Same-day BS3621 mortice and anti-snap lock change across Wallington — end-of-tenancy re-keys for letting agents and landlords, BS3621 mortice for the Edwardian terraces along Park Hill and Woodcote Road, and anti-snap upgrades on Roundshaw multi-point uPVC and composite doors. LBS Selective Licensing-ready paperwork included.
Wallington is in the London Borough of Sutton — not Croydon despite the proximity. The A237 Stafford Road spine cuts through, with three stations within a mile (Wallington, Hackbridge, Carshalton), Edwardian terraces along Park Hill and Woodcote Road, and the distinct Roundshaw former-airfield estate to the south. Across Stafford Road, Park Hill, Woodcote Road, Stanley Park Road, Park Lane and London Road the housing stock splits between Edwardian and late-Victorian terraces (1890–1910) along Park Hill, Woodcote Road and Manor Road, the Roundshaw former-airfield estate (1960s + late-90s mixed multi-point/composite stock), and 1930s semis on Park Lane, plus a steady mix of post-war social housing and 1990s–2010s new builds. That means our top three jobs here every week are: BS3621 insurance upgrades on Edwardian Park Hill front doors, end-of-tenancy re-keys on Roundshaw multi-point flats for LBS letting-agent clients, and Southern-line commuter lost-key reissues.
From 1 April 2026, London Borough of Sutton's borough-wide Selective Licensing Scheme covers every private rental in Wallington — the LBS scheme is distinct from Croydon LBC and Merton frameworks. Roundshaw letting agents and Edwardian-terrace landlords on Park Hill need LBS-specific paperwork on every let, alongside the existing LBS Additional HMO Licensing for any property with 5+ tenants. Whichever side of that you're on, our fitting receipts list the lock model, the BS3621 kitemark reference, the date, and the new key count — paperwork-ready for licence inspections, deposit protection, and insurance.
For the period-feature timber front doors on the streets behind Wallington Wallington railway station and around Woodcote Road Park, we fit BS3621 5-lever mortice deadlocks from £180 plus a Yale 89 or Union 1332 nightlatch. For the uPVC flat doors stacked across the conversion stock, it's a standard euro cylinder change from £135 or an anti-snap SS312 Diamond upgrade from £200.
Southern-line commute workers around Wallington railway station on Manor Road also use us heavily — late finishes, lost keys after the last Southern-line train, key-safe installs for letting-agent handover access. Whichever you need, moving in, ending a tenancy, or just an honest fixed quote for an anti-snap upgrade — book a same-day slot. From £89 fitted, fixed price first, no call-out fee.
Wallington jobs lean letting-agent and HMO — tenancy turnovers, licence-ready receipts, retrofits on Edwardian Park Hill terraces. Same engineer, same fixed-price-first promise.
The everyday SM6 job — every external lock changed on the day the new tenant collects keys, receipt for the agent or landlord with lock model and key count for deposit-protection records and Selective-Licensing-ready paperwork.

From £350 fittedPolice-recommended C-rated key safes mounted into masonry — Burton, Supra C500, Master Lock 5440. Common request from Southern-line commuter renters and Roundshaw letting-agent handovers on Manor Road and the surrounding Edwardian-terrace streets. Fitted and code-set on the day.

Tell us the SM6 postcode and the door type — Edwardian Park Hill timber, Roundshaw 1960s multi-point uPVC, or a late-90s Roundshaw composite. If it's a tenancy or HMO job, mention licence requirements so the receipt drops in landlord-ready format.
Croydon-based, DBS-checked, ID badge on. We assess the door, measure the cylinder or mortice pocket, confirm the price, check whether the lock needs a basic swap or a BS3621 / anti-snap upgrade for insurance or licensing.
Old lock out, new lock in, every key tested in both directions. Fitting receipt with lock model, key count and kitemark reference emailed to you and the agent. 12-month workmanship warranty. Card or cash on the day.
No call-out fee. The price below is what you pay — parts, labour, fitting receipt (landlord-ready where needed), 12-month workmanship warranty included.
Same engineer, same van — but the lock we fit changes depending on whether it's a Victorian terraced front on Park Hill, a Roundshaw 1960s multi-point uPVC, a late-90s Roundshaw composite, or a 1930s Park Lane semi, or a Stanley Park Road post-war composite.
1890–1910 solid-timber Edwardian front and back doors along Park Hill, Woodcote Road and Manor Road. We fit BS3621 kitemarked mortice deadlocks alongside a quality nightlatch — LBS Selective Licensing-ready paperwork supplied with every fit.
Wallington's signature multi-point job: a Roundshaw 1960s former-airfield-estate flat with a uPVC composite multi-point door, often with a worn gearbox after 50 years of letting cycles. Euro cylinder swap is the standard tenancy-change job — we recommend an anti-snap upgrade as standard for any pre-2011 cylinder.
Pockets of post-war housing and 1990s composite replacement doors across the western fringes. These run a euro cylinder inside a multipoint strip. Anti-snap cylinder upgrade is the standard treatment plus gearbox tolerance check.
Commercial-above-residential flat-above-shop doors along the A237 Stafford Road corridor. Often need anti-pick high-security cylinders, key-alike configuration for one-key access, and key safe install for letting-agent handover access.
We've been changing locks across Wallington since 2015 — 10+ years of tenancy-handover work, HMO retrofits and Victorian-terrace BS3621 jobs. Letting agents along Stafford Road and the Roundshaw estate have us on speed-dial because the receipts arrive emailed to the agent the same evening, formatted for licence inspections and deposit-protection records.
No call-out fee, no surprise charges, no upsell. Fixed price first, paperwork-ready fitting receipt after, and a 12-month workmanship warranty as standard.

Three recent SM6 jobs in three different sub-areas. Every review from a verified Google customer.
Original Edwardian terrace on Park Hill. Aviva renewal flagged the existing 5-lever as non-BS3621 — needed an insurance-grade mortice upgrade on the front door. The engineer matched the original brass furniture, fitted the kitemarked lock by 11am and emailed paperwork to the broker the same afternoon. Honest, polite, no upsell.
Lost the only key set on the Southern service from London Bridge. WhatsApp'd him at 7pm with the address, the engineer was on Stanley Park Road inside 45 minutes, evening lock change and two spare keys cut on the van. Fixed price quoted on the message. Saved me from a hotel and a Monday morning panic.
Between-tenants change on a 1960s Roundshaw flat — the multi-point gearbox had failed and the previous tenant had a habit of leaving spare keys with anyone. He sorted the gearbox, swapped to an anti-snap cylinder, fitted a coded key safe for the new check-in. LBS Selective Licensing paperwork emailed before he left. First-class engineer.
