Most Eltham bookings fall into one of these six patterns. Pick the closest match — we'll quote the right brand and price on WhatsApp before we arrive.
Easiest, cheapest path: cylinder swap on the existing lock body, old keys retired the same visit. Typical fit: 30 minutes. Best for terraced and 1930s semis where the lock body is otherwise fine.
Common on Mottingham, Avery Hill, and Eltham South 1930s semis with original 3-lever mortice. We fit an ERA Vectis or Union 2134E 5-lever BS3621 — kitemark stamped on the keep, receipt with the reference for your policy file.
The Estate is Grade II conservation, but the external brass is what's protected, not the internal mechanism. We lift the original brass escutcheon, swap the internal case to BS3621, refit the brass. No listed-building consent needed.
Whoever has the lost key may have an address from the keyring or bag contents. Faster and safer than waiting to see what happens: full cylinder swap, fresh keys cut, the lost set permanently retired. Around 45 minutes on a Euro door.
Standard mid-tenancy cylinder swap or BS3621 mortice replacement. We can issue 2-3 fresh keys for the new tenant + a managed master copy for you. Receipt emailed with kitemark reference for your HMO file.
A loose or sticky cylinder is a sign it's tired and at risk. Replace with TS007 3-star anti-snap or Sold Secure Diamond. Insurance-compliant, snap-resistant, fitted in under 30 minutes. Common on Eltham South Euro-profile doors.
Phone-around quotes wobble by area, day, and even the operator who picked up. Pre-booked on WhatsApp gives you a fixed number before anyone touches your door — and lets us bring the right hardware for your Eltham housing stock first time.

Three things make lock work in Eltham different from a generic London suburb. First, the Progress Estate — a Grade II conservation area of around 1,300 Arts-and-Crafts homes by Frank Baines (1915) wrapping Well Hall, Ross Way, Gregory Crescent, Phineas Pett Road, and the streets above. External brass face-furniture is protected by the listing, so locks are swapped internally and the original face-fittings refitted to the existing holes.
Second, the 1930s semi belt across Mottingham, Avery Hill, Westmount Road, and Eltham South. Most of these front doors still run their original 3-lever mortice lock, which UK home insurers haven't accepted as primary security since the late 1990s. A like-for-like upgrade to a Union 2134E or ERA Vectis 5-lever BS3621 is the staple Eltham service. Third, the heritage geography — Eltham Palace (English Heritage), Well Hall Pleasaunce, the medieval-origin High Street — means much of the housing stock around the centre is conservation-area stock with the same listed-mech rules as the Progress Estate.
Every part of SE9 — from the Progress Estate listed cluster through the 1930s semi belt to Eltham South and Mottingham. Pre-booked appointments across the area most days of the week.
From Eltham High Street through Mottingham and Eltham Park to the green belt edge.

★★★★★ 5.0 Google rating · 155 reviews"Our Progress Estate door has the original 1915 brass — they lifted it off, swapped the internal mech for a BS3621 5-lever, refitted the brass exactly as it was. Listed-building rules respected, insurance happy, no consent application needed."
Cassia W.Well Hall, Progress Estate
"1930s semi, the insurer flagged the old 3-lever mortice as below standard. Booked Saturday morning, fitted a Union 2134E 5-lever in 45 minutes, emailed me the kitemark receipt straight to my policy file. Clean job, fair price."
Aaron M.Westmount Road
"Lost my house keys at the gym. WhatsApp'd them at 11am, fitted a new Euro cylinder by 3pm, fresh keys cut on the day. No callout fee, no upsell, the same price they quoted on the message. Will use again."

Pre-booked appointments across SE9 — Progress Estate, Mottingham, Avery Hill, Eltham High Street, Eltham South. WhatsApp a photo of the door and we'll send a written quote within minutes. Card or cash accepted on completion, no callout fee.
Six things customers in SE9 ask us most often — covering price, lead time, whether you need to be home, brands, insurance compliance, and Progress Estate listed-building rules.
Headline floors: lock replacement from £89 (non-BS3621 night latch), Euro cylinder change from £135, BS3621 5-lever mortice from £180, anti-snap kitemark cylinder from £200. Every quote is fixed in writing on WhatsApp before we arrive — no callout fee, no surprises on the day. Card or cash accepted.
Same-day appointments are usually available across SE9 — Eltham High Street, the Progress Estate, Mottingham, Avery Hill, Eltham South, and the streets around Well Hall and Westmount Road. Most pre-booked lock changes complete in 30 to 60 minutes on site. WhatsApp a photo of the door and we will confirm a same-day or next-day slot at a time that suits you.
Yes — someone needs to be at the property to let us in, hand over the old keys, and accept the new set on completion. The fit typically takes 30 to 60 minutes. You don't need to clear the room, move furniture, or do any prep beforehand. If you can't be home, a trusted neighbour, partner, or letting agent with door access works equally well — just confirm in advance and we'll bring spare receipt copies for both parties.
We stock Banham M2002 restricted-key cylinders for Progress Estate listed villas, Mul-T-Lock MT5+ for matched-suite Edwardian flat conversions, Union 2134E BS3621 5-lever mortice for Mottingham/Avery Hill/Eltham South 1930s semi insurance upgrades, ERA Vectis BS3621 for period mortice on Edwardian villas south of Eltham High Street, plus Yale, Avocet ABS, and Ultion on request.
Most UK home insurance policies require BS3621-rated locks on final exit doors and pay out only if the lock fitted meets that standard. We fit kitemark-stamped 5-lever mortice and Sold Secure cylinder products on every BS3621 job. For Euro-profile uPVC and composite doors we recommend a TS007 3-star kitemark anti-snap cylinder (manufactured to standards verified by the Door & Hardware Federation) or a Sold Secure Diamond cylinder (soldsecure.com). We include the kitemark reference on every installation receipt so you can attach it directly to your policy file.
Yes. The Progress Estate (Frank Baines, 1915) is a Grade II conservation area of around 1,300 listed Arts-and-Crafts homes laid out across Well Hall, Ross Way, Gregory Crescent, Phineas Pett Road, and the surrounding streets — managed by the Royal Borough of Greenwich. External door furniture is protected by the listing, so on a Progress Estate front door we lift the original brass escutcheon plate, replace the internal lock case with a BS3621-rated 5-lever mortice keyed to a new set, and refit the original brass face-fittings to the existing holes. No listed-building consent is needed for an internal mechanism swap.
Quick prep that gets you a sharper quote and avoids any surprises on the day — listed-building check, insurance compliance, and brand sanity-check.
If your address is on Well Hall, Ross Way, Gregory Crescent, Phineas Pett Road, or the surrounding streets, you're on the Grade II listed garden suburb. Tell us when you message — we'll quote an internal-mech swap that keeps the original brass in place (no listed-building consent needed).
Most UK insurers want BS3621-rated locks on final exit doors. Check the lock-spec clause before booking — if your insurer named a specific standard (BS3621, TS007 3-star, Sold Secure Diamond), share it with us so we bring the matching brand.
One photo of the door from the outside, one close-up of the lock body or cylinder. With those two images we can quote the right brand, the right cylinder length, and the right time on site — usually in under 10 minutes on WhatsApp.
