What type of window handle you have determines the replacement you need
Before you can replace a window handle, you must identify which type you have. The three most common UK handle types are cockspur, espagnolette, and tilt-and-turn. A cockspur handle is a simple lever found on side-hung casement windows, with a single striker plate that catches on a keep fixed to the window frame. An espagnolette handle has a square spindle that turns a multi-point locking mechanism, common on uPVC windows. A tilt-and-turn handle has a push-button or lever mechanism that allows the window to either tilt inward or open fully.
Yes, you can replace a window handle yourself in under 30 minutes. First identify your handle type (cockspur, espagnolette or tilt-and-turn), then match the spindle length (typically 35mm) and fixing centre distance (43 or 92mm) to ensure a perfect fit.

You can identify each type by visual inspection. Cockspur handles have a visible striker plate on the handle itself. Espagnolette handles have a square spindle that disappears into the lock mechanism. Tilt-and-turn handles have a button or lever on the face of the handle that switches between tilt and open modes. You must match the spindle length, backplate dimensions, and fixing hole spacing — typically 43mm or 92mm centre distances for espagnolette handles — to ensure the new handle fits correctly (GGF technical guide on handle compatibility, 2026).
Quick numbers handle sizes, spindle lengths, and fixing centres
| Handle type | Common spindle length (mm) | Fixing centre distance (mm) | Typical backplate width (mm) |
|---|---|---|---|
| Espagnolette | 35 | 43 or 92 | 25–30 |
| Cockspur | 30–40 | 43 (single centre) | 20–25 |
| Tilt-and-turn | 30 | 43 or 92 | 25–30 |

How to remove the old handle without damaging the window frame
To remove the old handle, first locate the screw caps or covers on the backplate. These are often hidden under a small plastic cover that prises off with a flat-head screwdriver. Once the caps are off, unscrew the two or four fixing screws and pull the handle away from the frame. For espagnolette handles, note the spindle position — horizontal or vertical — before removal to avoid forcing the lock mechanism.
If the handle is seized, apply WD-40 or a similar penetrating oil to the spindle entry point and wait 10 minutes before attempting removal. Do not use excessive force, as this can damage the window frame or the lock mechanism. The GGF homeowner guide to uPVC window maintenance recommends this method for seized handles (GGF homeowner guide to uPVC window maintenance, 2026).
The direct answer replacing a standard espagnolette window handle
Remove the old handle as described, then measure the spindle length — the distance from the backplate to the tip — and the fixing centre distance. Select a replacement with identical spindle length and fixing centres. Most UK DIY stores stock the standard 43mm or 92mm pattern. Insert the new handle’s spindle into the lock mechanism, ensuring it aligns with the square drive. Screw the backplate into the original screw holes, then replace the screw caps. Test the handle cycles smoothly through open, closed, and locked positions before final tightening (GGF step-by-step replacement guide, 2026; Which? survey on common DIY window repairs, 2026).
The cost of a replacement espagnolette handle typically ranges from £8 to £25 depending on the brand and finish. You can buy them from most hardware stores or online retailers. Ensure the replacement handle matches the original in both spindle shape and fixing centres, as mismatched parts can cause the lock to fail.
When you need a replacement cockspur handle and how to fit it
Cockspur handles have a single striker plate that engages with a keep on the frame. The handle itself is a simple lever. To remove it, unscrew the two screws on the backplate, lift the handle away, and note whether the spindle is round or square. Replacement handles are available with either spindle shape, so you must match the shape and length — typically 30–40mm. You may also need a matching striker plate if the original is worn.
Fit the new handle by inserting the spindle into the keep on the frame, then screw the backplate into the original screw holes. Ensure the striker plate aligns with the keep on the frame. If the handle does not latch securely, adjust the keep position by loosening its screws and moving it slightly until the handle catches properly (GGF technical note on cockspur handle replacement, 2026).
How to verify your replacement handle is correctly installed and secure
After fitting, check the handle operates without resistance through its full range. If it sticks, the spindle may be too long or the fixing screws are over-tightened. Test the lock engagement by closing the window, turning the handle to the locked position, and attempting to open the window. It should not budge. For espagnolette handles, verify that the multi-point lock shoots fully into the keep on the frame. A partially engaged lock can cause the window to rattle or let in draughts (FENSA installation standards for window hardware, 2026; DESNZ energy efficiency guidance for airtight windows, 2026).
Check the handle is flush against the frame with no gaps. If the backplate does not sit flat, the spindle may be too short or the fixing holes may be stripped. In that case, you may need a handle with a longer spindle or use wall plugs to secure the screws.
Which certification and installer checks apply to window handle replacement
Replacing a handle is a minor repair and does not require FENSA certification or Building Regulations approval if the window frame and glazing remain unchanged. However, if the handle replacement is part of a wider window repair or replacement, the work must comply with Part L of the Building Regulations and be certified by a FENSA-registered installer. For double-glazed windows, ensure the new handle does not interfere with the sealed unit’s integrity. A poorly fitted handle can create a thermal bridge, reducing the window’s energy efficiency (GOV.UK guidance on Building Regulations for replacement windows, 2026; FENSA consumer advice page, 2026).
If you are uncertain about the correct handle type or installation, consider hiring a FENSA-registered installer. They can ensure the handle is fitted correctly and that the window meets current energy efficiency standards.

Frequently Asked Questions
Measure the spindle length (typically 35mm for espagnolette), fixing centre distance (43mm or 92mm), and backplate width (25–30mm). The GGF technical guide (2026) states these dimensions determine compatibility.
Pry off the screw caps with a flat-head screwdriver, then unscrew the fixing screws. The GGF recommends pulling the handle straight away from the frame to avoid twisting or cracking the uPVC.
Espagnolette handles with a 35mm spindle and 43mm fixing centre distance are most common on uPVC windows, according to the MCS technical bulletin 003 (2026).
Yes, it is a straightforward DIY task. You just need to match the spindle length, fixing centres, and backplate dimensions. The GGF guide confirms no specialist tools are required.
A new window handle costs £5–£20 from UK hardware stores or online. Replacing it yourself saves on labour, but a professional call-out adds £40–£80 (GGF, 2026).
