Services for Landlords
From end-of-tenancy cylinder swaps to emergency tenant lockouts — we support private landlords and letting agents across London with prompt, upfront-priced service.
Cylinder replacements on front doors, back doors, and communal entrances at the end of every tenancy. We fit BS3621-compliant cylinders — including TS007 3-star anti-snap options such as Ultion or Brisant Secure — and provide fresh keys for incoming tenants.
Tenants locked out of the property — we respond promptly any time of day or night across London. We gain access with minimum disruption and can change the cylinder at the same visit if required.
Many buy-to-let insurance policies require BS3621-certified locks. We supply and fit rated cylinders and mortice locks that satisfy insurer requirements — and can provide written confirmation of the work for your records.
uPVC multi-point lock failures, wooden door deadlocks, misaligned frames, and broken door furniture repaired or replaced on the same visit in most cases. We stock common parts for Winkhaus, Fullex, and GU Ferco systems.
Running multiple rental properties? A master key system lets you hold one key for all properties while each tenant's key opens only their front door. We plan and fit master key suites for portfolios of any size.
Written confirmation of all lock changes and upgrades — useful for insurance claims, deposit disputes, letting agent audits, and council compliance checks.

FAQ
While not a legal requirement, changing locks between tenancies is strongly recommended. You cannot guarantee a previous tenant has not copied keys. A cylinder change is low cost and gives new tenants confidence in their security — and may be required by your landlord insurance policy.
At minimum a BS3621-certified mortice deadlock or cylinder. For uPVC doors we recommend a TS007 3-star rated anti-snap cylinder such as Ultion or Brisant Secure. These satisfy most buy-to-let and landlord insurance requirements and are significantly harder to defeat by snapping — the most common forced entry method on uPVC doors.
Yes. We respond promptly for tenant lockouts across London, any time of day or night. We gain access without damaging the door where possible and can replace the cylinder at the same visit if needed.
No — there is never a call-out fee. We give you an upfront fixed quote before we start. You pay only for the work we complete.
