Window Lock Installation, All Types Covered

Sash Window Locks

Sash windows are common in Victorian and Edwardian properties. You can find these types of window locks around the most popular areas in London, such as Kensington, Notting Hill, and South Kensington. Even if they look good, they can be vulnerable if the original catch is the only protection. Call our team of locksmiths, and we will assist you with fast lock installations such as:

  • Sash window stops – prevent the window from being pushed open from the outside
  • Key-operated sash locks – allow ventilation while keeping the window secure
  • Dual screws – bolt both sashes together for maximum strength

If you live in a period property or listed building and want a lock that doesn’t compromise the look of your original windows, give us a call anytime. Our locksmiths will be in touch and will advise on the right option.

Casement Window Locks

We can also help with casement windows. These are the hinged, outward-opening style locks. Most times, you can find them installed on modern and period homes. Of course, you would need the right lock for the frame material. We can install window locks for:

  • Timber casement windows
  • Aluminium casement frames
  • uPVC casement windows

A locksmith has to come over and perform a house security assessment so he would be able to assist you properly. We can help with key-operated locks, espagnolette bolts, and friction stays. Be sure that our experts will know how to make it work and will match the lock to the frame to ensure a good and lasting fit.

uPVC Window Locks

uPVC windows typically have a multi-point locking mechanism built in, but the handles and gearboxes wear out over time. You can be sure that a worn mechanism is no longer securing your window properly. Most times, we get calls for patio uPVC locks that are broken or not functioning properly. Also, we can assist with locks for your garden or house office.

Get in touch, as we can replace any faulty uPVC window handles and gearboxes. Moreover, sometimes we can even add supplementary window restrictors or key locks where needed. So, if your uPVC window isn’t locking flush or the handle feels loose, call us. It’s a quick fix that makes a real difference to your security, and our experts would be happy to assist anytime.

Tilt & Turn Window Locks

Tilt and turn windows are popular in modern apartments and new-builds across West London. The multi-position mechanism can develop faults that prevent the window from locking in either position. We service, repair, and replace tilt and turn window lock mechanisms, and fit additional security locks where the standard fitting isn’t enough.

Fanlight & Skylight Locks

High-level windows and fanlights are frequently overlooked – but they’re sometimes the easiest point of access for an intruder. We fit lockable fanlight stays and skylight bolts to ensure every opening in your home is properly secured.

Why Window Security Matters in Kensington

Window locks aren’t just about burglary prevention. Your home insurer will expect ground-floor and easily accessible windows to be fitted with key-operated locks as a minimum. In many cases, failing to have them fitted means a claim won’t be paid.

If you’ve recently moved into a property in Kensington, Holland Park, or South Kensington and you’re not sure what locks are on your windows – or whether they meet your insurer’s requirements – book a home security assessment, and we’ll check every window and door for you.

Insurance-Approved Window Locks

We only fit window locks that meet BS standards and are recognised by UK home insurers.

If your insurer has specified a particular type of lock, let us know, and we’ll source and fit the correct product.

We carry a wide range of stock for same-day fitting.

Window Lock Repair

Locks can seize, jam, or fail – especially in older timber windows where the wood has swollen or the lock hasn’t been serviced in years. If your window lock is:

  • Stiff or hard to turn
  • No longer catching properly
  • Broken or damaged
  • Missing a key

…call us. In many cases, we can repair or rekey the existing lock rather than replace it, saving you time and money.

FAQ – Window Locks

Q: Do I need key-operated window locks for my home insurance?

Most UK home insurers require key-operated window locks on all ground-floor windows and any windows accessible from a flat roof, fire escape, or adjacent structure. Check your policy schedule or call your insurer – and call us if you need locks fitted quickly.

What is the best window lock for a sash window in Kensington?s that are BS3621 rated?

For period sash windows, a combination of sash stops and a key-operated dual screw offers the best security without altering the character of the window. We’ll advise on the right product for your specific window when we arrive.

Can you fit window locks the same day?

Yes. We carry stock for the most common window types and can usually fit locks on the same day you call. For less common frame types, we’ll confirm availability before we visit.

My uPVC window handle is broken – can you fix it?

Yes. A broken or worn uPVC window handle usually means the gearbox mechanism needs replacing. This is a straightforward repair we carry out regularly across South West and West London.

How long does window lock installation take?

A single window lock typically takes 15–30 minutes. Fitting locks across multiple windows in a property takes 1–2 hours, depending on the number and type of windows.
