Streatham SW16 · Lock Change & Upgrade
Lock change in Streatham — tenancy, HMO and Victorian-terrace work, done same day.
Streatham is the core of SW16 — the long retail spine of Streatham High Road (the A23), the open green of Streatham Common and The Rookery, and three stations at Streatham, Streatham Common and Streatham Hill. The housing behind it is unusually layered: late-Victorian and Edwardian terraces around Telford Park and the side streets off the High Road, inter-war mansion blocks along the High Road and Streatham Hill, and a deep band of conversion flats and HMOs carved out of the larger terraces. That mix means our top three jobs here every week are end-of-tenancy re-keys, keyed-alike sets for converted flats, and BS3621 or anti-snap upgrades for landlords.
Streatham sits in the London Borough of Lambeth, and Lambeth's selective licensing scheme now covers the Streatham wards — every privately rented home must be licensed, with penalties for unlicensed lets. The borough's HMO Article 4 direction across Streatham Common & Vale and St Leonard's tightens the rules again. 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 Lambeth licensing inspections, deposit protection, and insurance.
For the period timber front doors on the streets around Streatham Common and up toward Streatham Hill, we fit BS3621 5-lever mortice deadlocks from £180 plus a quality nightlatch. For the uPVC and composite doors on the conversion flats and newer developments off the High Road, it's a standard euro cylinder change from £135 or an anti-snap TS007 upgrade from £200. Communal mansion-block doors take a mortice or nightlatch with managed key control.
Whether you're moving in to an Edwardian terrace near the Common, ending a tenancy on a flat off Streatham High Road, or want an honest fixed quote for an anti-snap upgrade — book a same-day slot. From £89 fitted, fixed price first, no call-out fee.

I run several HMO rooms in a converted Streatham terrace, and they changed every lock, keyed two of the doors alike, and documented the whole job for my Lambeth licence in a single visit. The receipt listed each lock model and key count exactly how the inspector wanted it. Same-day, fixed price, completely straightforward.

We had just bought an Edwardian terrace near Streatham Common and our buildings insurer wanted the old front-door mortice brought up to a BS3621 5-lever deadlock. They explained exactly why, fitted a kitemarked lock with a nightlatch above, and gave us a receipt for the insurer. Tidy work, honest pricing, polite engineer.

End-of-tenancy re-key on my converted flat off Streatham High Road — they changed the front and back locks and keyed them alike so the new tenant had a single key before move-in day. Booked in the morning, done the same afternoon, fixed price with the receipt emailed straight over. Exactly what I needed.

Lock Change Streatham — FAQs
Common questions from SW16 letting agents, landlords and tenants.
Seven questions we hear week-in, week-out across Streatham.
How much does it cost to change a lock in Streatham?
Lock change in Streatham starts from £89 for a basic external cylinder swap — the standard tenancy-change job on SW16's conversion-flat front doors. Standard euro cylinder change is from £135, BS3621 5-lever mortice is from £180 (the common upgrade on the Victorian and Edwardian terraces around Streatham Common and Streatham Hill), full lock replacement from £189, and an anti-snap TS007 cylinder from £200. Fixed price first, no call-out fee.
Do you do same-day tenancy-change lock work for Streatham landlords and letting agents?
Yes — same-day tenancy lock change is our highest-volume SW16 job. Streatham sits inside Lambeth's selective licensing scheme and the borough's HMO Article 4 direction across Streatham Common & Vale and St Leonard's. We provide a fitting receipt with the lock model, key count and BS3621 kitemark reference for landlord records, deposit-protection paperwork, and Lambeth licensing inspections. From £89 per door, portfolio pricing available.
What lock should I fit on a Victorian terraced house in Streatham?
Victorian and Edwardian terraced front doors across Telford Park, Streatham Hill and the side streets off Streatham High Road take a BS3621 5-lever mortice deadlock as the main lock (kitemarked for insurance) plus a quality nightlatch above. We fit BS3621 mortice from £180 and provide a paperwork-ready fitting receipt for your insurer or Lambeth licensing inspector.
How much is an anti-snap cylinder upgrade in Streatham?
An anti-snap upgrade is from £200 fitted — a TS007 3★ cylinder (Ultion, Avocet ABS or Yale Platinum), new keys, removal of the old cylinder, and any handle adjustment. Most conversion-flat and newer composite front doors across SW16 still have the original builder's-spec cylinder. Lock-snapping is the no.1 forced-entry attack on UK doors — the upgrade typically pays for itself in one year of insurance excess.
Can you change locks the same day my new tenancy starts in Streatham?
Yes — move-in-day lock change is one of our most common Streatham jobs. Previous tenants, agents, cleaners and contractors may still hold keys. We change every external lock on the day you collect them and supply receipts for the agent or landlord. Same-day across SW16, with a typical arrival window from our CR0 3SR base.
Do you keyed-alike the locks on a Streatham HMO or converted flat?
Yes — keyed-alike is one of the most requested jobs on Streatham's conversion-flat and HMO stock. We can set a flat's front and back doors, or a row of mansion-block doors, to a single key, and document the key count and lock model for Lambeth licensing and managed key control. Same-day across SW16, from £89 per door.
Do I need a BS3621 lock for insurance on a Streatham HMO?
Most UK home insurance policies require a BS3621 5-lever mortice deadlock on every final-exit timber door, or a multipoint locking system on uPVC and composite doors. For HMOs and converted flats, the BS3621 kitemark stamped on the faceplate is the standard your insurer and Lambeth's licensing inspector will look for. We fit BS3621 mortice locks from £180 across SW16 and supply a fitting receipt with the kitemark reference.
How long does a lock change take in Streatham?
Most jobs take 20–45 minutes. A straight euro cylinder swap on a conversion-flat front door is under 30 minutes — the most common Streatham job. A BS3621 mortice on a Victorian terrace timber door takes 45–60 minutes because the lock body sits inside the door edge and needs precise alignment. Multipoint gearbox swaps on uPVC and composite doors run 60–90 minutes.BS3621 5-lever mortice deadlock on every final-exit timber door, or a multipoint locking system on uPVC and composite doors.
