Lock change services we book across Hither Green
Six pre-booked services covering every door type we see across the Corbett Estate, Hither Green Lane conversions, Manor Park flats, and the modern blocks around Hither Green station. Same-day fits where the diary allows.
BS3621 mortice fit
5-lever kitemark locks for Corbett Estate front doors. Union 2134E or ERA Fortress, insurance-compliant.
Euro cylinder upgrade
Avocet ABS or Yale Platinum anti-snap cylinders for Hither Green Lane ground floor and modern flat doors.
Landlord batch upgrades
4 to 8 doors in one visit on the Corbett Estate. Same lock case across every door, one fee, one schedule.
Tenant turnover re-pin
Quick cylinder re-pin between tenancies. Same lock body, fresh keys, no door damage.
Lost-keys cylinder swap
If you don't know who has your spare set, the cylinder gets swapped, not just re-pinned. Old keys become useless.
Night latch and rim lock fits
Front door secondary security. Yale 89 or Era Fortress night latches over an existing 5-lever mortice.
Six common Hither Green lock change scenarios
These are the actual jobs we book most often in SE13. If yours sounds like one of these, we can probably price it on the WhatsApp before we leave the workshop.
"I'm a Corbett Estate landlord booking 4 doors in one visit"
Corbett's uniform door dimensions mean the same Union 2134E BS3621 case drops into every front pocket. We schedule the route, fit 4–8 doors in a morning, and you get one written invoice.
"I just bought a Hither Green terrace — I want fresh keys"
Standard handover advice: change the front and back cylinders so previous owners, builders and estate agents can't get back in. Usually under an hour for a Corbett terrace.
"My insurer said I need a BS3621 lock"
Standard insurance language for the final exit door. We fit a 5-lever ERA Fortress or Union 2134E and email you a receipt naming the standard so the claim file is clean.
"I'm a landlord — tenant moved out, new one moves in next week"
Re-pin the existing cylinder rather than replacing the whole lock. Same body, fresh keys, fraction of the cost. Booked around the new tenant's move-in date.
"I lost my spare set and don't know who has it"
If you don't know where the key is, re-pinning isn't enough — the cylinder gets swapped. Old keys become useless. We carry stock so it's same-visit.
"My ground-floor Euro cylinder is loose or worried about snap"
Hither Green Lane and Manor Park conversions have street-visible cylinders. Avocet ABS or Yale Platinum anti-snap upgrades close the snap-attack gap in 30 minutes.
Why pre-book your Hither Green lock change instead of calling around?
Pre-booking is cheaper, calmer, and gives you a written price before any tools come out of the van. Four reasons it works better than chasing last-minute rates.
-
1
Cost certainty before we arrive
Written quote on WhatsApp first. No mystery "while we're here" upsells. You see the BS3621 lock price, the cylinder price, the labour, all itemised.
-
2
Brand choice, not "what the van has"
You pick between Union 2134E, ERA Fortress, Avocet ABS, Yale Platinum. We carry the kitemark BS3621 stock the Corbett Estate front doors actually need.
-
3
Right hardware loaded in advance
For Corbett batch upgrades we load 4 to 8 matching Union cases before leaving. For Hither Green Lane flats we bring the anti-snap Euro stock. No second visit needed.
-
4
Fit time at YOUR schedule
Book around school runs, tenant move-ins, or letting agent visits. We block the diary slot rather than fitting you between other jobs.
Which lock brand should you pick in Hither Green?
Four matched recommendations based on the actual housing stock we work on in SE13. The lead pick is the Corbett Estate landlord answer, because that's the most-booked job on this page.
Union 2134E BS3621 5-lever
BS3621 Kitemark · 22mm bolt
The Corbett Estate's uniform mortice pockets mean one Union 2134E case fits every front door. Same lock across the portfolio makes key management and tenant handovers easier — the reason this is our default landlord pick.
See the 5-lever mortice spec →ERA Fortress BS3621
BS3621 Kitemark · single-property fit
Single-property workhorse for Corbett period mortices. Kitemark-rated, accepted by all UK home insurers, and one of the easier 5-levers to handover keys for if you're selling soon.
BS3621 explainer →Avocet ABS Anti-Snap Euro cylinder
TS007 3-star · SS312 Diamond
Hither Green Lane conversion ground floors have Euro cylinders visible from the pavement. Avocet ABS carries both the TS007 3-star and Sold Secure Diamond standards — closes the snap-attack window in under 30 minutes.
Anti-snap cylinder spec →Yale Platinum Euro cylinder
TS007 3-star · modern block default
Post-2000 flats around Hither Green station default to Euro cylinders. Yale Platinum is the kitemark-rated upgrade that satisfies insurance terms and resists snap, pick, and drill attempts.

Lock change Hither Green — what makes SE13 different?
Hither Green sits inside the London Borough of Lewisham, with the postcode SE13 spreading from the Catford border down to Lewisham Hospital. The defining feature for lock work is the Corbett Estate — 3,000+ Victorian terraces built by Archibald Cameron Corbett in the 1890s on a tight grid covering Beacon Road, Sandhurst Road, Theodore Road, Springbank Road, Embleton Road, Hither Green Lane, Hazelbank Road, Inchmery Road, Earlshall Road, and Verdant Lane. Every one of those front doors has near-identical mortice pocket dimensions, which means a single Union 2134E BS3621 case drops into thousands of doorways without packing or rebating.
That uniformity is why we get more landlord batch upgrade bookings in Hither Green than anywhere else in the 17-page lock change series. Outside the estate, Hither Green Lane itself runs Edwardian conversions above the parade of shops, and the streets around Hither Green station and Lewisham Hospital tilt towards modern blocks where Euro cylinders dominate. We work to Sold Secure Diamond standard on anti-snap upgrades and follow DHF TS007 3-star guidance on every cylinder we fit. Landlords with 5+ unrelated tenants must hold a mandatory HMO licence under Lewisham Council's HMO scheme, and Hither Green ward also falls under additional licensing for 3-4 person HMOs — both schemes specify BS3621 final exit doors.

"Booked a batch fit on four of my Corbett houses on Beacon Road. They turned up at 8am, fitted four matching Union 2134E mortice locks across all four front doors before lunch, and emailed me one invoice with the BS3621 standard named on it. Best landlord-friendly visit I've had this year."
Florence W.
Beacon Road, Corbett Estate
☆☆☆☆☆
"My flat sits above the parade on Hither Green Lane and the front door cylinder was getting wobbly. They came round on a Tuesday afternoon, swapped it for an Avocet ABS anti-snap, and walked me through why the kitemark sticker matters for my insurance. Done in 35 minutes, polite throughout."
Magnus J.
Hither Green Lane, Edwardian conversion
☆☆☆☆☆
"Lost a spare set somewhere in the school run between Mountsfield Park and home. Didn't fancy a panic call so I WhatsApp'd the next morning, got a written quote in minutes, and they re-pinned the cylinder mid-tenancy that afternoon. Same key shape, fresh cuts, peace of mind."

Lock change questions from Hither Green homeowners
The six questions we get asked most often before booking. If yours isn't here, send it via WhatsApp and we'll come back the same day.
How much does a lock change cost in Hither Green?
Lock change Hither Green SE13 starts at £89 for a standard night latch swap. Euro cylinder upgrades from £135, BS3621 5-lever mortice fits from £180, and anti-snap upgrades from £200. You get a written quote before any work starts — no hidden callout fee. Card or cash accepted on completion.
How long does a Hither Green lock change take?
Most lock changes in Hither Green take 30 to 60 minutes. A single Euro cylinder swap is closer to 30 minutes; a BS3621 mortice fit on a Corbett Estate front door is 45 to 60 minutes because the timber depth needs careful chiselling. Batch upgrades for landlords (4+ doors) are timed in advance so the visit runs to schedule.
Do I need to be home when you fit the lock?
Yes, someone needs to be home or onsite to give access and accept the work. For Corbett Estate landlords doing batch upgrades, a letting agent or property manager can meet us at each door — we just need a contact name and number per appointment. We won't fit a lock and post the keys through the letterbox.
Which lock brands do you fit on Corbett Estate doors?
Corbett Estate front doors are unusually uniform — same mortice pocket dimensions across thousands of houses. We default to Union 2134E BS3621 5-lever for landlords doing batch fits (same lock across every door), and ERA Fortress BS3621 for single-property owners. Both are kitemark-rated to Sold Secure Diamond and meet UK home insurance terms. For ground-floor flats above Hither Green Lane shops we recommend Avocet ABS anti-snap Euro cylinders, certified by DHF to TS007 3-star.
Will my home insurance cover the new lock?
UK home insurance policies typically require a BS3621-rated lock on the final exit door. Every BS3621 lock we fit in Hither Green comes with a written invoice naming the standard — that's what insurers ask for if you ever need to claim. We can email the receipt the same day. For HMO landlords, Lewisham Council's licensing scheme also specifies BS3621 final exit doors.
Can you do same-day batch upgrades for landlords on multiple Corbett doors?
Yes — Corbett Estate's uniform door dimensions mean the same lock case drops into every front door, so we can fit 4 to 8 BS3621 mortice locks in a single morning visit. Book one slot, give us the addresses, and we plan the route so labour stays under one visit fee. Card or cash accepted on completion. We carry stock for Union 2134E and ERA Fortress in the van so you don't wait on parts.
Three things every Hither Green homeowner should know
Quick context that saves money and stops insurance arguments. Worth a read before booking, especially if you've just moved into a Corbett terrace.
Corbett Estate doors are interchangeable
The 1890s Corbett build used standard mortice pocket dimensions across thousands of front doors. That means one Union 2134E case fits Beacon Road, Sandhurst Road, and Theodore Road without packing. It also means a portfolio landlord can hold one spare in the garage instead of one per address.
Lewisham HMO licensing covers BS3621
Hither Green ward sits inside both Lewisham's mandatory HMO scheme (5+ unrelated tenants) and the additional/selective licensing tier (3–4 person HMOs). Both schemes require a BS3621-rated lock on the final exit door — check the council's HMO page for the exact wording before a tenant moves in.
Hither Green Lane flats need anti-snap
The Edwardian conversion flats above the parade on Hither Green Lane have Euro cylinders that are visible from the street. Snap-attack is the dominant method on those doors, so we default to Avocet ABS or Yale Platinum anti-snap, both TS007 3-star and Sold Secure Diamond, rather than a basic Euro swap.
