All services in Oxford →Strike plate alignment on southern terrace properties varies by frame material: Bath stone frames carry the keep in the stone rebate, Brighton brick frames in mortar-set timber keep pads, and Cardiff rendered terrace frames in the render layer over brick. Each substrate requires a different keep-fixing approach, and the substrate is confirmed before the keep position is drilled.
On the day
Fitting day in Oxford — the five-step sequence
New locks go in against a defined sequence, not ad-hoc. Here's the order each of our engineers works through on a typical Oxford installation — the same on a terraced front door as on a new-build UPVC back door.
- 01
Confirm parts and measurements
Before any tools come out we walk through the hardware that's been ordered for your Oxford property — cylinder sizes, gearbox type where relevant, strike plate dimensions, and any fire or insurance ratings. If something's a size off, we reschedule rather than force the fit.
- 02
Prep door and frame
Existing furniture is removed, the door checked for square and for any swelling or drop on the hinges. On older OX1 stock the frame often needs a chisel adjustment at the keep; on new-build doors it's usually a clean lift and drop. Anything structural that's out of scope is flagged before we go further.
- 03
Fit the hardware
Cylinder, gearbox, multipoint strip, or mortice case goes in against the manufacturer's template. Fixings match the frame material — steel screws into softwood, self-tappers into aluminium, no-slip fixings into composite. Nothing is over-torqued; we document predictable failure modes on job card before any fixing is committed to final torque.
- 04
Align and test
Every operation is tested with the door both open and closed — key in, key out, handle lifted, deadlock thrown, thumb-turn from inside. On a multipoint we test each hook and shoot-bolt independently before signing off. Anything that binds gets adjusted there and then, not "later".
- 05
Handover and keys
Keys are counted against the job card and handed over with a one-page written summary: what was fitted, the lever stack corrosion mode spec noted, serial numbers where relevant, and a seven-day follow-up window. On insurance-graded installs the compliance paperwork lands by email the same day.
What we measure
Four measurements that decide the fit in Oxford
Failure mode documentation: both coastal corrosion and lime mortar keep movement are noted on the job card at installation with their expected timescales. Inspection interval set and recorded. Customer briefed on what to report and when.
-
Door thickness
44 / 54 / 70 mm
Determines whether the standard cylinder length fits flush or needs a long-body variant.
-
Backset
45 / 60 / 70 mm
Distance from the edge of the door to the centre of the cylinder. Common on UK doors but not universal.
-
Euro cylinder length
30/30 → 45/55
Measured separately from each side of the door. Must sit flush — too proud and the cylinder is vulnerable to snapping.
-
Frame material
Timber · Composite · Aluminium
Oxford stock varies widely. Frame material dictates fixings, strike plate type, and the correct spec for the lever stack corrosion mode.
- Lever stack corrosion on coastal properties is predictable and can be managed by specifying a higher-grade coating at installation — this is documented so future installers understand the specification decision.
- Lime mortar keep movement is a slow process but progressive — a keep that was correctly set at installation may need repositioning after 10–15 years of lime mortar compression.
- Predictable failure record on the job card allows a future installer to quickly identify the likely cause of a reported fault without a full re-survey.
Pricing — what shifts it
What affects a Oxford lock installation price
Reading Victorian terrace stock close to the town centre is often in HMO orconverted tenure, where the landlord's insurer may require a higher BS3621grade than the existing installation carries. The compliance gap isidentified on arrival and the upgrade cost confirmed before any hardware ischanged. From £59.
- 01
New-fit vs like-for-like replacement
Fitting into an existing cut-out is cheaper than routing a new one. Period doors in Oxford often need a fresh cut; UPVC is almost always like-for-like.
- 02
Hardware tier
Standard cylinder sits at the base price; TS007 3-star anti-snap, BS3621 mortice, and restricted keyways each add to the parts cost.
- 03
Door condition
A square door on tight hinges fits fast. Drop at the hinge side, swelling, or a warped strike plate adds time — we flag this during the measurement call, not at the end.
- 04
Number of doors on the same visit
Fitting front, back, and garage side-door in one appointment is meaningfully cheaper than three separate visits across Oxford.
Lock Installation in Oxford — FAQ
Common questions about lock installation in Oxford.
Can you install a lock on a brand-new door?
Ipswich and Norwich flint-and-brick terrace properties have frames thatinclude flint nodules at the rebate face. These resist modification: theframe is treated as fixed and the hardware selected to fit withoutadjustment. The frame composition is confirmed at survey and the casespecification adjusted accordingly. Yes — this is one of our most common installation jobs in Oxford. 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 Oxford 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 Oxford — do the locks already meet insurance standards?
Not always. Many Oxford 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.
