π Safety at a Glance: The Essentials
- The Risk: Over 4,000 children under 15 are injured falling from windows in the UK every year (ROSPA).
- The Fix: Child Restrictors limit the opening to safe levels (100mm) while allowing ventilation.
- Retrofit: You don’t need new windows; we can fit cable restrictors to almost existing frame.
- Commercial Duty: Care homes and landlords have strict legal obligations to prevent falls.
The figures speak for themselves. According to the Royal Society for the Prevention of Accidents (ROSPA), falls from windows are a significant risk to young children, especially during the summer months when windows are left open for ventilation.
But itβs not just about children. The Health and Safety Executive (HSE) highlights increasing risks for vulnerable adults, particularly in care settings. Whether you are a parent, a landlord, or a care home manager, securing your windows is a legal and moral priority.

1. How to Childproof Your Windows
The most effective way to prevent accidents is to install restrictors. These devices limit how far a window can open, preventing a child from falling out while still letting fresh air in.
Critically, modern restrictors are built to withstand significant force. A high-quality restrictor is tested to hold against forces of 500N (approx 50kg) or more. This means even if a child stumbles and falls against the window, the restrictor will hold the sash firmly in place.
2. Cable vs. Integral: Which is Best?
There are two main types of restrictors available. Which one you choose depends on whether you are fitting new windows or securing existing ones.
| Feature | Cable Restrictor | Integral Hinge Restrictor |
|---|---|---|
| How it Works | A visible steel cable connects the sash to the frame. | Built inside the friction hinge mechanism. |
| Visibility | Visible (can be a visual deterrent). | Hidden when closed. |
| Installation | Retrofit: Screws into any existing frame (uPVC/Timber). | New Install: Usually fitted when manufacturing the window. |
| Operation | Key release (very secure). | Push-button or stud release (easier for adults). |
| Best For | Existing homes, rentals, & care homes. | New build windows & clean aesthetics. |
3. The 100mm Rule & Regulations
Why do restrictors stop at 10cm? This comes from Building Regulations aimed at preventing falls.
The rule of thumb (often cited in Approved Document K regarding protection from falling) is that a sphere of 100mm diameter should not be able to pass through any gap. This represents the size of a small child’s head. If the head can’t pass through, the body won’t follow.
β οΈ Landlord Responsibility
If you rent out a property, you have a duty of care under the Housing Health and Safety Rating System (HHSRS). If a window has a low sill height (less than 800mm from the floor) on an upper storey, it is classed as a ‘Fall Hazard’. Installing restrictors is a low-cost way to ensure tenant safety and limit your liability.
4. Safety in Care Settings
At KJM Group, we work extensively with commercial clients, including care homes and hospitals. In these environments, the risks are higher due to vulnerable adults who may be confused or at risk of self-harm.
For these settings, standard domestic restrictors may not be enough. We supply heavy-duty commercial restrictors that:
- Can withstand aggressive force (far exceeding 50kg).
- Are “Tamper Proof” (cannot be released without a specialist tool held only by staff).
- Are permanently fixed to the reinforcement inside the window profile.
If you manage a care facility in Hampshire, contact our commercial team for a safety audit.
5. Security vs. Fire Escape
This is the most common concern: “If I restrict my windows, how do I escape in a fire?”
This is why we never recommend permanently screwing windows shut. Modern restrictors are designed to be releasable for emergency egress.
- Key Release: Keep the key nearby (in a known place, but out of reach of children) so an adult can unlock the cable in an emergency.
- Push-to-Release: Some integral hinges have a “press and slide” release mechanism intended for adult use during emergencies.
6. Frequently Asked Questions
Yes. Cable restrictors are universally compatible. They can be screwed into uPVC, Timber, or Aluminium frames. KJM can supply and fit these for you to ensure they are screwed into the reinforcement, not just the plastic.
While the fall risk is lower, restrictors on ground floor windows are excellent for security. They allow you to leave the window open for ventilation without opening it wide enough for an intruder to climb in.
Not always. While many locking handles use a standard “cut,” cable restrictors often have their own specific keys. We recommend keeping all window keys in a known, safe location in case of fire.
