Electric gates are covered by safety law in a way most homeowners never hear about until something goes wrong. The rules exist because gates have killed people. In the summer of 2010, two young children died in separate accidents with automated gates, one in Manchester and one in Bridgend. A company was later convicted of corporate manslaughter over the Manchester death, and investigators found that built-in safety features had been overridden when the gate was installed. The rules that follow are what stand between a gate and that outcome.
An Automated Gate Is Legally a Machine
In the UK, a powered gate is machinery. When it is first supplied or put into service, it falls under the Supply of Machinery (Safety) Regulations 2008. The Health and Safety Executive explains that whoever designs and makes a powered gate, which can include an installer assembling it from components, must comply, and that the gate must come with a written Declaration of Conformity and comprehensive user instructions.

The Installer Becomes the Manufacturer
This is the point most people miss. When an installer puts a motor kit on a gate, or motorises an existing manual gate, they create a new machine and become its manufacturer in law. That means they must make sure it is safe, compile a technical file, give you instructions, issue a Declaration of Conformity in their own name, and fix conformity marking to the gate. Government guidance updated in 2025 confirms that either CE or UKCA marking can be used in Great Britain. The same duties apply when existing gates are automated as when a new gate goes in.
If your installer leaves without handing over a Declaration of Conformity and instructions, the job is not finished. That paperwork is your evidence that the gate was designed and tested as a safe machine.
BS EN 12453 and the Force Limits
The technical standards behind the law are BS EN 12453, which covers safety in use, and BS EN 12604, which covers mechanical aspects. HSE noted in 2018 that the 2017 editions replaced four older standards. The current edition of BS EN 12453 includes a 2021 amendment. The key requirement is force: a closing gate that meets a person must not crush with more than 400 newtons or strike with more than 1,400 newtons, and forces should be as low as possible.
The only way to know a gate meets those limits is to measure it with a calibrated force meter. The Door and Hardware Federation has measured forces of over 1,000 newtons on gate edges, and has highlighted a firm that relied on a hand test instead of a meter. A hand pushed against a closing gate tells you nothing reliable about the force.
What a Safe Gate Needs
HSE lists the hazards of powered gates as being hit by the moving gate, crushed against fixed or moving parts, trapped, caught on gears, electrocuted, and gates falling or being blown over. A safe installation deals with each one. Pressure-sensitive safety edges or force-limited motors stop and reverse the gate on contact, backed up by photocells across the opening. Gaps at the hinge side are guarded or designed out. Sliding gates have proper end stops and anti-fall supports so they cannot come off their track. The gate is force tested and the results recorded.
That last point about sliding gates is not theoretical. In April 2025 Kent Trading Standards secured a prosecution after a 400 kilogram sliding gate installed by a firm from Tonbridge came off its guides and crushed a homeowner, causing life-changing injuries. A plain guide roller had been used where a proper travel stop was needed.
Gate Safe
Gate Safe, the UK charity for automated gate safety, was founded in 2010 by Richard Jackson in response to the two children's deaths. It runs installer training and a register of installers who have completed it, and recommends that automatic gates are serviced every six months by a trained installer. Its training is an easy first filter when choosing an installer.
What the Law Asks of Homeowners
HSE is clear that a homeowner has no legal health and safety duties for their own private gate, although regular checks are strongly advised. Landlords, managing agents and businesses that control gates do have duties. But a homeowner can still be sued if their gate injures someone or damages property, because the ordinary law of negligence and the duty of care owed to visitors still apply.
That is where servicing matters. A log book showing six-monthly servicing with force tests is strong evidence that you took reasonable care. A gate that has not been checked for years, with safety devices disabled or out of adjustment, is far harder to defend.
When a Gate Hits a Car
Disputes over gates closing on cars come up regularly. In one MoneySavingExpert thread from October 2024, a caterer leaving a client's house said the gates closed onto their car, while the homeowner claimed around £8,000 for damage to the gates. Replies pointed out that a properly working gate should stop or reverse when it detects a vehicle. Who pays in a case like that turns on the facts: whether the gate's safety devices were working, whether it was maintained, and whether the driver acted reasonably. CCTV, the gate's service records and its commissioning paperwork are the evidence that settles it.
A Short Safety Checklist
Before you sign off a new or automated gate, make sure you have a Declaration of Conformity, user instructions, a conformity plate on the gate, the risk assessment and the force test results. Check that the gate has safety edges or force limitation as well as photocells, that the hinge side and any gaps are protected, and that a sliding gate has end stops and cannot fall. Know where the manual release is. Then book servicing every six months. An automated gate system installed this way is a safe, legal machine; one installed without these steps is a liability at the end of your drive.
If You Think Your Gate Is Unsafe
If a gate does not stop or reverse when it should, closes with more force than you would expect, or has damaged or missing safety edges, stop using the automatic function. Switch it to manual using the release, or isolate the power, and keep children and pets away from it. Then ask a trained installer to inspect and force test it. If the gate is new and you believe it was installed unsafely, raise it with the installer in writing; Gate Safe has a form for reporting concerns, and Trading Standards deals with unsafe machinery.
Gates at Rented Homes, Flats and Businesses
The position changes as soon as a gate is not simply a private homeowner's. Landlords, managing agents and employers who control gates used by tenants, residents, staff or the public do have legal duties under health and safety law to keep them safe. That means a maintenance regime, records of inspections and force tests, and acting on faults promptly. If you let a house with automated gates, or manage a block with a shared gate, treat servicing as a legal obligation rather than an option.
None of this makes automated gates unusually dangerous when they are done properly. Millions of people use them safely every day. The risk comes from gates installed without the safety devices, set up without a force test, or left without servicing until the settings drift. Knowing what the law expects lets you check that your gate meets it, and ask the right questions before anything goes wrong.
