Electric gates are powered machinery. They generate significant force, move without warning, and operate in environments where children, pets, and visitors are regularly present. The safety requirements for electric gate installations in the UK exist because in 2010, two child fatalities involving powered gates prompted the HSE to investigate the standards then in place and conclude that they were not sufficient. The current standard, BS EN 12453:2017, was strengthened as a direct result.
This guide explains what the safety requirements actually mean in plain language, which safety devices are legally required, what your obligations are as a homeowner after installation, and what CAME approved status means in terms of safety compliance.
The Legal Framework
The starting point is the Supply of Machinery (Safety) Regulations 2008, which is the UK implementation of the Machinery Directive. Under these regulations, any powered gate installed in the UK must meet essential health and safety requirements and be accompanied by a Declaration of Conformity confirming compliance. The gate and its automation system must carry UKCA marking for installations after January 2023.
Supporting the regulations are two technical standards:
BS EN 12453:2017 sets the safety performance requirements for power-operated gates and doors. It covers force limitation, safety device requirements, risk assessment obligations, control system requirements, and what documentation must be provided at handover. This is the standard your installer is working to when they carry out commissioning and force testing.
BS EN 12445:2017 sets the testing methodology for verifying that the gate meets the force limits required by EN 12453. Force testing requires calibrated measurement equipment. It cannot be carried out by eye or by hand.
Together, these standards mean that a gate installer in the UK cannot simply hang a gate, fit a motor, and hand the keys over. They are legally required to carry out a site-specific risk assessment, specify and install appropriate safety devices to address each identified risk, test the gate to BS EN 12445 using calibrated equipment, produce a technical file documenting the risk assessment and test results, and issue a Declaration of Conformity confirming the system meets the regulations.
If your installer did not provide a Declaration of Conformity at handover, your installation does not have the documentation it is legally required to have.
The Required Safety Devices
Safety Photocells
Safety photocells are the primary detection device on every electric gate. Two sensor units are mounted on the gate posts, one on each side of the entrance, at a height of approximately 300 to 400mm above the ground. They send an invisible infrared beam between them. When the beam is broken by a person, vehicle, or object, the gate stops immediately and reverses.
Photocells are required on all electric gate installations. A gate without photocells is not compliant. Photocells must be positioned correctly to provide genuine protection across the gate travel path, not positioned at a height or angle that only detects vehicles and misses a pedestrian or child at low height.
Safety Edges
Safety edges are pressure-sensitive rubber or PVC strips fitted to the leading edge of the gate leaf, the edge that moves toward the closed position. When the safety edge contacts an obstruction, it triggers the gate to stop and reverse. Safety edges provide protection where the photocell beam may not reach, particularly at close range when the gate is near fully closed.
Safety edges are a consumable component. They degrade through UV exposure, repeated compression, and weathering. A safety edge can fail its compliance test while appearing visually intact. Annual testing is the only reliable way to confirm a safety edge is still performing within the required limits.
Force Limitation
The motor’s closing force must be calibrated so that even if both the photocell and the safety edge fail to detect an obstruction, the gate cannot exert more than the maximum force permitted by BS EN 12453. The force limits are defined in Newtons and must be measured with a calibrated force testing device, not estimated.
Force limitation is set at commissioning and must be re-verified annually because motor performance and gate mechanical resistance change over time. A gate whose force was within limits at installation may exceed them two years later due to hinge stiffening, post movement from London clay seasonal shift, or motor wear.
Manual Release
Every electric gate installation must include a manual release mechanism that allows the gate to be moved by hand when the motor is not powered or has a fault. The manual release must be accessible without specialist tools, must be demonstrated to the property owner at handover, and must be clearly labelled on the motor housing.
A gate without a functioning manual release is both non-compliant and a practical hazard. If the power fails, the gate must be openable by hand for emergency vehicle access.
Automated Gate Warning Signs
Warning signs must be displayed on or adjacent to the gate to alert pedestrians and visitors that the gate may move without warning. This is a specific requirement under the standards and applies to residential installations as well as commercial ones.
What Happens at Handover
A compliant electric gate installation in London must include the following documentation at handover:
Declaration of Conformity. Confirms the installation meets the Supply of Machinery (Safety) Regulations 2008. Signed by the installing company.
Force test results. The measured force readings from the calibrated test carried out at commissioning, confirming the gate is within the EN 12453 limits.
Risk assessment. The site-specific risk assessment carried out by the installer before and during installation.
User instruction. How to operate the gate, how to use the manual release, who to contact for service, and what the annual maintenance requirement is.
If you did not receive these documents at handover, contact your installer and request them. If your installer cannot provide them, the installation may not be compliant and you carry legal liability for any incident involving the gate until a compliant inspection and documentation is obtained.
Your Ongoing Obligations as a Homeowner
The legal obligations do not end at installation. As the property owner operating a powered gate, you have ongoing responsibilities under the HSE’s powered gate safety guidelines.
Annual safety testing. Safety devices degrade over time. Annual testing by a qualified engineer using calibrated equipment is the recognised standard for residential gates. The testing covers force compliance, photocell function and alignment, safety edge sensitivity, manual release operation, and a general mechanical inspection. Documented annual safety checks also protect homeowners from liability in the event of an incident.
Responding to faults promptly. A gate that is reversing unexpectedly, moving slowly, or showing any change in normal behaviour should be assessed before continued use. Many safety device failures manifest as behavioural changes before a complete failure occurs. See our electric gate not working guide for a symptom-by-symptom diagnosis framework.
Maintaining battery backup. The battery backup on a CAME motor system allows the gate to operate during a power cut and provides a power source for the safety devices. A flat battery does not just mean the gate will not open during a power cut. It means the safety devices may not function correctly during that period. Battery replacement every three to five years is standard maintenance practice.

What CAME Approved Means for Safety
NOVA Gates & Railings is a CAME approved installer. CAME approval is not purely a commercial certification. It includes training on installing and commissioning CAME motor systems to EN 12453 standard, which covers the force testing procedure using calibrated equipment, the safety device specification and positioning requirements, and the commissioning documentation that must be produced at handover.
A non-approved installer fitting CAME motors may not have completed the force compliance training, may not have access to the calibrated testing equipment required to verify compliance, and the CAME manufacturer warranty may not apply to work carried out outside the approved network.
This matters particularly in London and Surrey where a significant number of gate installations are carried out by general tradespeople who add gate installation to a broader fencing or landscape offer without the specific safety training the work requires. The consequence is gates that look correct but have not been properly force-tested or documented.
Every electric gate installation by NOVA Gates & Railings includes a full Declaration of Conformity, calibrated force test results, and safety device commissioning documentation at handover. These are not optional extras. They are part of what a compliant installation requires.
Common Safety Failures on London Gate Installations
The following are the most frequent safety compliance failures found on existing London gate installations during service visits.
No safety edges fitted. The single most common compliance failure on older installations. Safety edges were often omitted on budget installations before the standards were better understood and enforced.
Photocells at incorrect height. Photocells fitted at vehicle detection height rather than pedestrian detection height. A beam at 600mm height detects a car but misses a child crouching or crawling near the gate travel path.
Force settings too high. Gates commissioned without calibrated force testing frequently operate at forces significantly above the EN 12453 limits. The motor is set to a default power level rather than a calibrated compliance level.
No manual release demonstration. Manual releases that exist but have never been tested or demonstrated to the household. In the event of a power failure, no one knows how to open the gate.
Battery backup not replaced. Batteries past their service life that no longer hold charge. During a power cut, the safety devices have no power source.

Frequently Asked Questions
Are electric gates a legal requirement to comply with safety standards in London?
Yes. Any powered gate installation in the UK must comply with the Supply of Machinery (Safety) Regulations 2008, supported by BS EN 12453 and BS EN 12445. This applies to domestic residential properties as well as commercial sites.
What is EN 12453?
BS EN 12453 is the UK and European safety standard for power-operated gates and doors. It sets out the required safety devices, force limits, and testing requirements that every electric gate installation must meet.
What safety devices does my electric gate legally need?
Safety photocells, safety edges on the leading edge of the gate leaf, force limitation within defined limits, a manual release mechanism, and an automated gate warning sign displayed at the entrance.
How often should an electric gate be safety tested?
Annual safety testing is the recognised standard for residential installations. More frequent testing applies to high-usage commercial and multi-user gates.
What does CAME approved mean for safety?
A CAME approved installer has completed training to install and commission CAME motor systems to EN 12453 standard, including force testing with calibrated equipment. This training is a direct safety qualification, not just a commercial certification.
