Window Restrictor Fitting in Liverpool

Who needs window restrictors?

• Families with young childrenBedroom and landing windows above ground floor are the main concern, especially where a bed, radiator or windowsill gives a child something to climb on.
• LandlordsRestrictors on upper windows are a common request when preparing a let. Check your tenancy agreement and current official guidance for your own duties.
• Flats and taller housesSecond-floor bedrooms and stairwell windows where a fall would be serious.
• Homes with vulnerable adultsRestrictors can reduce risk for someone with dementia or other conditions, as long as escape is still planned for.
• Security and ventilationSome people like to leave a window slightly open for air without it swinging wide in the wind.

What types of window restrictor are there?

Many restrictors limit the first opening to around 100 mm, a gap generally treated as too small for a young child to pass through. We check the actual gap on each window once fitted, because the geometry of the sash and hinges affects how wide the opening ends up.

Restrictors and escape windows

This is the most important part of choosing restrictors. In many homes, an upstairs bedroom window is the planned way out in a fire. Planning Portal guidance describes an escape window as having a clear openable area of at least 0.33 m², with width and height each at least 450 mm, and the bottom of the opening no more than 1100 mm above the floor. A restrictor that cannot be released quickly would defeat that purpose.

So on an escape window we fit restrictors that an adult can override easily without tools, or, where a key-locking type is chosen, we recommend keeping the key close to the window, out of a child’s reach but where an adult can find it in the dark. We talk through which windows in the house are escape routes before deciding what goes where.

Can restrictors be fitted to any window?

Most uPVC casement windows can take a cable restrictor or restrictor stays. Aluminium windows often can too, though fixings and hinge sizes vary more between systems; see our aluminium window and door repair page for more on older aluminium frames. A few things can make fitting harder:

• Very narrow frame sections where there is little room for screws away from the glass.
• Sashes that drop or rub, which need the hinges sorting first so the restrictor works smoothly.
• Old hinges from discontinued systems, where a matching restrictor stay may not be available and a cable type is simpler.
• Tilt-and-turn gear, which has its own mechanism and needs care; see tilt and turn window repair.

Restrictors, locks and handles together

A restrictor limits the opening; a lock stops the window being opened at all. On children’s bedroom windows, a lockable handle adds a second layer, so the window can only be opened by someone with the key. If your handles are loose or the locking points no longer engage, our pages on window handle replacement and uPVC window lock repair cover those fixes. We can usually check and sort handles at the same visit as the restrictors.

How we fit window restrictors

1. Talk it through. We ask how many windows, which rooms, who lives in the house and whether any windows are used as escape routes.
2. Look at the windows. We check the hinge type, frame material and the condition of the sash, and point out any faults worth fixing first.
3. Agree the type. We recommend a restrictor for each window and give you a written quote.
4. Fit and test. Restrictors are often fitted at the first visit if we carry the right parts; restrictor stays may need ordering. We test each one, show you how to release it, and check the window still opens fully when released.

Simple checks you can do yourself

• Open each upstairs window and see how wide it goes. If a child could lean out, a restrictor is worth considering.
• Check existing restrictors catch every time, and that you know how to release them quickly.
• Move furniture away from upstairs windows so there is nothing to climb on.
• Keep any restrictor or handle keys in the same agreed place, known to every adult in the house.

What affects the cost?

The number of windows, cable restrictors versus restrictor stays, any lockable handles, the frame material and whether hinges need replacing first. We do not give prices over the phone without knowing the windows, but our repair cost guide explains the factors behind most window hardware quotes.
