We ask whether this is a new door with no existing lock, a replacement on an old one, or an additional lock (e.g. on a rear door). Door type — wooden, UPVC, composite — tells us what hardware to bring.
Lock installation work in Leicester is usually scheduled rather than emergency. Same-day or next-day slots are standard; weekends available without surcharge.
Engineer measures the door, checks frame condition, and advises on the right lock grade. Insurance requirements — BS3621 on wood, 3-star on UPVC/composite — are confirmed before fitting.
Lock installed including any chiselling or drilling required, tested through full key cycle, and BS3621 / TS007 compliance record issued on completion.
Situations we handle
Builder or carpenter has hung a new front or back door on modern city centre apartments in Leicester but left the locking hardware to a specialist. We measure the rebate, chisel precisely for a BS3621 mortice case, fit the lock and strike, and test.
Our approach Accurate chiselling to match a BS3621 case; strike plate aligned; cylinder or nightlatch paired as appropriate.
Renovation project across a post-war council estate propertie in Leicester, all external doors need new hardware. We scope the whole property in one visit, fit locks to BS3621 / TS007 3-star throughout, and co-ordinate keyed-alike setups where the customer wants fewer keys on the ring.
Our approach Scheduled installation across all external doors; keyed-alike matching where requested; full written compliance pack on completion.
Door type drives most of the work in Leicester, not the lock itself — the matrix below breaks the prep down by the three we see most often.
By door type
Hardware choice
Door type, rebate, standards, and keyed-alike — before the first chisel goes in
On a timber final-exit door, a BS3621 5-lever mortice deadlock is the insurance-grade choice: the bolt projects into the frame and can't be forced by pushing or spreading the door. A nightlatch alone is insufficient — it provides convenience, not security. The correct installation is a BS3621 mortice plus a BS-rated nightlatch: one for deadlocking overnight, one for daytime convenience. We measure the rebate depth and stile width before selecting a case.
On UPVC and composite doors, the multipoint mechanism is operated by a euro cylinder. The cylinder is the only meaningful security component — and the most commonly compromised one. We specify TS007 3-star anti-snap cylinders on every new UPVC installation: anti-snap, anti-pick, anti-drill, and anti-bump rated. The cylinder size (e.g. 35/35, 40/40, 45/45) must match the door profile — we measure on site and cut the correct size from van stock.
If a door already has a mortice pocket from a previous lock, fitting a new BS3621 case is quick — the chisel work is minimal. If the door has no existing cutout (brand new door, or converted opening), accurate chiselling takes an additional 30–60 minutes per door. We quote based on what's actually there, not a flat rate — new-rebate installs are priced to reflect the additional labour.
Belgrave and Highfields back-to-back terraces retain original narrow 2" mortice cases — replacement stock often has to be sourced from specialist trade suppliers

Common questions about lock installation in Leicester.
Yes — this is one of our most common installation jobs in Leicester. Carpenters and joiners often hang the door and leave lock fitting to specialists. We measure the rebate, chisel for a BS3621 mortice case, fit the strike plate, and test through a full key cycle. Finished work looks factory-fit.
Yes — if you want one key to open your front and rear doors, we supply keyed-alike cylinders on the most common profiles. Arrange at the survey stage so we bring matching parts. This works cleanly on UPVC euro cylinders and on certain mortice profiles.
Yes — weather-rated padlocks, BS-grade hasps, garden gate locks, and shed/garage door hardware are all regular installation work across Leicester. We match the lock to the exposure (weatherproofing matters outdoors) and fit on the same visit.
Not normally. Most door manufacturers specify that lock installations must be done by a competent locksmith — we are, and we fit to manufacturer-approved positions and dimensions. If in doubt, mention the door brand when you call and we'll confirm compatibility before attending.
