The short answer
Automated gates are classed as ‘machinery’ under the Supply of Machinery (Safety) Regulations 2008 and must be designed and installed to prevent crushing and entrapment. That means a risk assessment, safety devices (photocells, safety edges and correct geometry), force testing to BS EN 12453, CE/UKCA marking and a Declaration of Conformity. There have been fatal accidents in the UK involving non-compliant powered gates, which is why these rules are strict and why a powered gate is not a job for a general handyman. The strongest reason to use a competent, DHF or Gate Safe registered installer is that they carry out this safety work properly.
Of everything on this site, this is the page that matters most. An electric gate is convenient and secure, but it is also a powerful machine that moves heavy components near people, including children. Treated properly, it is perfectly safe; treated carelessly, it can crush or trap someone, and there have been deaths in the UK as a result — including children — from gates that lacked the required safety devices. The law reflects this. This guide explains, in plain English, what the regulations require, what a compliant installation looks like, and why this is the single best reason to choose your installer on competence rather than price.
What the law requires
- Treat the gate as machinery (SMSR 2008)
- Carry out a risk assessment
- Fit photocells and safety edges as needed
- Design out crushing points (correct geometry)
- Force-test to BS EN 12453
- CE/UKCA mark + Declaration of Conformity
Why an automated gate is ‘machinery’
When a gate is powered, it stops being a simple barrier and becomes a piece of machinery: something that moves under its own power and can apply significant force. Under the Supply of Machinery (Safety) Regulations 2008 (which implement the European Machinery Directive in UK law), the person who puts a powered gate into service — usually the installer — is responsible for ensuring it is safe, CE or UKCA marked, and accompanied by a Declaration of Conformity. This applies to brand-new automated gates and to existing gates that are being automated for the first time: the moment you add a motor, you have created machinery and the duties apply. This is the legal backbone of everything else on this page.
The main hazards: crushing, shearing and entrapment
The regulations exist because powered gates create specific physical hazards. Crushing happens when a closing gate traps a person or limb against a pillar or the ground. Shearing happens at points where moving and fixed parts pass each other, such as the gap between a sliding gate and its frame, or hinge areas on swing gates. Entrapment and drawing-in can occur where a child can be caught by an open infill or a moving rack. A competent installer identifies these hazards in a risk assessment and designs them out or guards them — this is what “correct geometry” means, and it is as important as any electronic sensor.
The safety devices that make a gate safe
A compliant installation uses layered protection so that no single failure leaves the gate dangerous:
- Photocells — infrared beams across the gate’s path; breaking the beam stops or reverses the gate.
- Safety edges — pressure-sensitive strips on the leading (and where needed trailing) edges that stop or reverse the gate on contact.
- Force limitation — the control board limits the motor’s force so the gate stops if it meets resistance, kept within the limits set by BS EN 12453.
- Correct geometry and guards — designing out or guarding crushing, shearing and drawing-in points so a person cannot reach a dangerous gap.
- Warning signage and a manual release — so the gate’s movement is signalled and it can be opened by hand in an emergency.
| Requirement | What it involves | Why it matters |
|---|---|---|
| Risk assessment | Identify hazards on the specific site | Basis for the whole design |
| Safety devices | Photocells, edges, guards | Stop/reverse on a person |
| Force testing | Measure impact force to BS EN 12453 | Proves limits are met |
| Declaration of Conformity | Signed statement + CE/UKCA mark | Records compliance |
| Annual service | Re-test devices and force | Keeps the gate safe over time |
Force testing and the Declaration of Conformity
Two outputs prove a gate is compliant. Force testing uses a calibrated gauge to measure the impact force the gate exerts at various points; the readings must fall within the limits set by BS EN 12453 (part of the BS EN 13241 family for power-operated gates). If the force is too high, the installer adjusts the control board, geometry or devices and re-tests. The Declaration of Conformity is a signed document, accompanied by CE or UKCA marking, in which the installer states the gate meets the regulations. Keep this paperwork — it is your evidence that the gate was installed properly, and it’s what a responsible installer always provides. A quote that doesn’t mention force testing or a Declaration of Conformity is a red flag, as our choosing an installer guide explains.
Keeping a gate safe over time
Compliance isn’t a one-off. Photocells can be knocked out of line, safety edges wear, and force limits drift as the gate ages, so an annual service that re-tests the devices and force is part of keeping the gate safe and legal — see our running and maintenance cost guide. The manual release must always work so the gate can be opened by hand in a power cut or emergency. Whether the gate is mains, battery or solar powered makes no difference to these duties — a solar gate is just as much machinery as a mains one. If you take one thing from this site, let it be this: insist on the safety work, and choose your installer accordingly.

Frequently asked questions
Are electric gates covered by safety regulations?
Yes. Automated gates are classed as machinery under the Supply of Machinery (Safety) Regulations 2008 and must be designed and installed to prevent crushing and entrapment. This requires a risk assessment, safety devices, force testing to BS EN 12453, CE/UKCA marking and a Declaration of Conformity. The duties apply to new gates and to existing gates being automated.
What safety devices does an electric gate need?
Typically photocells (infrared beams that stop the gate if broken), safety edges (pressure strips that stop the gate on contact), force limitation set by the control board, and correct geometry or guards to design out crushing and shearing points. The exact devices depend on the site-specific risk assessment.
What is force testing on an electric gate?
Force testing uses a calibrated gauge to measure the impact force a gate exerts at various points. The readings must fall within the limits set by BS EN 12453. If the force is too high, the installer adjusts the gate and re-tests. It proves the gate cannot apply dangerous force to a person.
Can a handyman install an electric gate?
It is strongly inadvisable. A powered gate is machinery with legal safety duties, and getting the risk assessment, safety devices and force testing right requires specific competence. Because non-compliant gates have caused fatal accidents, this work should be done by a competent installer, ideally DHF or Gate Safe registered, who issues a Declaration of Conformity.
