People spend a fortune protecting the front door and forget that 30% of UK domestic burglaries come through a window. Particularly ground-floor windows, particularly when they’re left on the latch in summer for ventilation.
Window locks aren’t expensive to fit and they make a real difference. Most windows in Southampton homes can be properly locked down for £20-£40 each.
What goes wrong with window security
- UPVc window keys lost, owner doesn’t know they were ever there, treats the window as ‘always unlocked’
- Sash jammers missing on sash windows, old sash windows are climbed-through routinely
- Bedroom windows above flat roofs, opportunist climbs the kitchen extension
- Ventilation locks not fitted, meaning windows must be either fully shut or fully open (people leave them open)
- Cracked window-lock cogs, lock turns but doesn’t engage anything
What we fit
UPVc window keys (replacement)
Lost the key for your white plastic windows? We cut new ones to the existing lock if it’s a standard profile. £10-£15 each, on the spot.
Sash jammers
For wooden sash windows. Discreet little brackets that prevent the lower sash being pushed up from outside, even when unlocked. £25-£35 fitted.
Ventilation locks
Lets the window open 4 inches for fresh air, no further. Critical for ground-floor and flat-roof-adjacent windows. £20-£30 fitted per window.
Restrictor stays
Ideal for upstairs windows in homes with young children. Window can’t open more than ~10cm, meets child safety guidelines and is also burglary-deterrent. £25 each fitted.
Sash window mortice bolts
Hidden surface-mounted bolts that lock the upper and lower sashes together. Old-school but effective. £20-£30 per window.
Insurance check
Most home insurance policies require window locks on all accessible windows (ground floor + first floor over flat roofs/extensions/etc.). Check your policy. If you’re missing locks, you might have unknowingly been uninsured for window break-ins. Free check during any other visit.
Common-sense tips
- Never leave windows open when you go out, even ‘just to the shops’
- Don’t leave keys in window locks visible from outside, easy steal through the letterbox or vent
- Bedroom over a flat roof? Treat it as a ground-floor window for security
- Don’t rely on the latch, a window ‘on the latch’ is unlocked

Common questions
How much does window lock repair cost in Southampton?
Depends what you need, but most window lock work in Southampton is straightforward and won’t break the bank. Replacement UPVC window keys run £10, £15 each, cut on the spot. Fitting a ventilation lock or sash jammer is typically £20, £35 per window. Everything’s quoted up front before I touch anything, and there’s no call-out fee. Most jobs I can get to same day. You’ll know the full cost before I start, no surprises on the invoice.
Can a locksmith fix a UPVC window lock that turns but doesn’t catch?
Yes, that’s a classic worn cog, the handle moves but nothing actually engages the locking points. It’s one of the most common window faults I see across Southampton and the Waterside area. Depending on the window, I’ll either repair the mechanism or replace the gearbox. Sometimes it’s quicker and cheaper to fit a new lock entirely. I’ll have a look, tell you honestly what’s needed, and quote up front. No call-out fee to come and assess it.
Do I need window locks for my home insurance to be valid?
Most home insurance policies in the UK require working locks on all accessible windows, that’s ground floor and any first-floor windows reachable from a flat roof, garage or extension. If yours are missing or broken, you could unknowingly be uninsured for a window break-in. Worth checking your policy wording carefully. I do a free check on window security during any visit. Covers Southampton, Hythe, Totton, Fawley and across Hampshire, give me a ring on 07453 327708.
What’s the best window lock for ventilation without compromising security?
A ventilation lock is exactly what you need. It lets the window open around four inches, enough for fresh air, not enough for a person. Fitted price is typically £20, £30 per window, and I carry them for most standard UPVC and timber frames. For sash windows, a sash jammer does a similar job. This is particularly useful for ground-floor windows and bedrooms over flat roofs, common in Southampton homes built in the sixties and seventies. Quoted up front, no call-out fee.
