The short answer
A powered school gate must detect a person or object in its path and stop and reverse before it causes harm, usually through safety edges and photocells. Council guidance for schools says powered gates should be inspected at least once a year by a competent gate engineer and included in termly site checks. Keep the installer's risk assessment, force test results, declaration of conformity and maintenance records on file.

An automatic gate solves a real problem on a school site: it keeps the vehicle entrance shut without someone having to walk out to it every time. It also brings a duty that a manual gate does not. A powered gate moves on its own, with real force, near children, and the school as owner or occupier is responsible for keeping it safe.
What makes a powered gate safe
The main risks are crushing and trapping: between the leaf and a post or wall, between a sliding gate and its end stop, or under a gate as it moves. A safe installation deals with each one.
| Device | What it does |
|---|---|
| Safety edges | Pressure-sensitive strips on the leading edge that stop and reverse the gate on contact |
| Photocells | Beams across the opening that stop the gate closing on anything in the way |
| Force limitation | Motor set so the gate pushes with no more than a tested force if it does touch someone |
| Guards and gap control | Mesh or covers so fingers cannot reach hinges, rollers or the gap behind a sliding gate |
| Manual release | A way to open the gate safely in a power cut or emergency |
Buckinghamshire Council’s guidance to its schools puts it simply: powered gates need sensors that detect a person or obstacle on either side, and must stop and reverse when something is detected.
How often to inspect
The same guidance asks for an inspection at least once a year by a competent engineer, and says termly site inspections should include a check and risk assessment of gates and barriers. Manual gates need documented inspection and maintenance too.
In practice many schools put powered gates on a maintenance contract with two visits a year, plus:
- a quick weekly check by the site team that safety edges and photocells stop the gate;
- an immediate stop on use if the gate behaves oddly, with the engineer called out;
- a check after any vehicle strike, however minor.
The records to keep
When a powered gate is installed or modified, ask the installer for:
- The risk assessment for that gate on that site.
- Force test results, measured at the closing edges.
- A declaration of conformity for the installed gate as a machine.
- The user instructions and maintenance schedule.
- A log book, for each service and repair.
Keep them with your site security records. If there is ever an incident, these are what show the gate was safe and maintained.
Choosing a competent installer
Gate Safe, a UK charity set up after a number of deaths involving powered gates, trains installers and keeps a list of those who have completed its training. Ask contractors whether their engineers are trained in automated gate safety, and ask to see the paperwork from a recent school job.
Gates and safeguarding
DfE’s security guidance stresses good access control in the school day. A powered vehicle gate helps, but it should be part of a wider plan: who can open it, from where, and at what times. Common choices are an intercom to the office for visitors, fobs for staff, and a timed lock outside drop-off and collection.
Never let a powered gate become the pedestrian route. Pupils and parents should use a separate pedestrian gate, which is safer and easier to supervise.
What it costs
Published UK contractor price guides in autumn 2026 put automation of a vehicle gate, including motor, safety edges and intercom, at about £1,500 to £4,000 on top of the gate, before VAT. A maintenance contract is extra. See school gates and access control for the full picture and the cost calculator to add gates to a fencing budget.
