All services in Aberdeen →The reference table for Victorian terrace doors focuses on the Timber column: the BS3621 mortice is your primary, the sash nightlatch or rim lock your supplementary, and any internal door hardware your add-on. Cylinder sizing for period doors is in the measurement guide below the matrix.

Euro cylinder sizing
Sizing — three references + how to measure your own
Getting the cylinder length right matters: too proud and it's vulnerable to snapping; too short and the key won't fully engage. Three common sizes, plus a four-step self-measure so we can quote without a site visit on straightforward jobs in Aberdeen.
- 35 / 35 70 mm symmetrical
- Flush both sides. Common on Aberdeen new-build composites where the frame uses a matched profile.
- 40 / 45 85 mm offset
- More common on UPVC front doors with a thicker external profile. The longer end faces outside.
- 45 / 55 100 mm (rarer)
- Used where the door is thicker than standard — some older composite doors and certain fire-rated frames.
Compliance
BS3621 & insurance — the short reference for Aberdeen installs
Period property pricing reflects door prep as much as hardware grade. If the existing mortice aperture is the right size for a BS3621 case the job is straightforward; if the door needs prep — rebate adjustment, aperture extension, strike-plate relocation — that is costed separately and confirmed on arrival. From £59.
-
Timber doors
BS3621 5-lever mortice deadlock
The original BS3621 reference. Kitemarked body, anti-drill, anti-pick, minimum 1000 key differs. Fitted to most insured timber front and back doors.
-
UPVC / composite
TS007 3-star euro cylinder + PAS 24 multipoint
"Equivalent" for euro-cylinder doors. 3-star cylinder carries anti-snap, anti-bump, anti-drill. Paired with a PAS 24 door/frame assembly it satisfies most standard clauses.
-
High-risk / restricted
EN1303 grade 6 — restricted keyway
Top of the range for cylinders. Keys can only be cut against a signed card. Specified where the risk assessment calls for a registered-key system or multi-property estate control.
Lock Installation in Aberdeen — FAQ
Common questions about lock installation in Aberdeen.
Can you install a lock on a brand-new door?
Victorian and Edwardian timber doors carry their own sizing constraints: rebate depth and stile width set what hardware will physically fit, before the compliance standard enters the conversation. Yes — this is one of our most common installation jobs in Aberdeen. 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.
Do I need BS3621 on a new installation?
For external doors on Aberdeen homes with standard insurance — yes, almost certainly. BS3621 is the minimum most UK home insurers specify on final-exit wooden doors. We fit BS3621 as standard and issue written paperwork confirming the standard for your insurance file.
Can you keyed-alike multiple new locks?
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.
We've just moved into a new-build in Aberdeen — do the locks already meet insurance standards?
Not always. Many Aberdeen new-builds come with entry-level euro cylinders on UPVC or composite doors that lack the TS007 3-star anti-snap rating, and sometimes a mortice case that predates BS3621 on the side door. We survey the whole property, identify any hardware gaps, and upgrade to compliant standards on the same visit — with a compliance pack for your insurer.
