What is this?
Electric gates use a motor to open and close automatically, controlled by remote fobs, keypads, intercoms, or sensors. When they stop working, access to your property can be blocked. Electric gates are increasingly common on UK residential properties.
Common causes
- Remote control battery dead
- Power supply to the gate motor interrupted
- Gate motor or gearbox failure
- Safety sensor or photocell blocked or faulty
- Control board fault
- Mechanical obstruction — debris, sagging gate, or damaged track
Is it dangerous?
A non-working electric gate is not an electrical safety risk. However, if the gate is stuck in the open position, your property security is compromised. Most electric gates have a manual release to allow you to open or close them by hand.
Can I fix it myself?
Replace the remote control battery. Check the power supply — look for a switched spur or isolator near the gate motor pillar. Check for obstructions blocking the gate or its safety sensors. Use the manual release key (usually provided at installation) to move the gate by hand. Clean any safety photocells — dirt on the lenses can prevent operation.
When to call an electrician
Call an electrician if the gate has power but the motor does not respond, if the control board shows a fault, if the gate is making unusual noises suggesting a mechanical issue, or if the safety sensors need recalibrating.
What will an electrician do?
Test the power supply and control board
Check the motor and gearbox for faults
Inspect and test safety sensors and photocells
Reprogram or replace the control board if needed
Realign the gate and adjust limit switches
Test all safety features after repair
Typical cost
£80 – £350
Simple repairs like sensor realignment or control board resets are at the lower end. Motor or gearbox replacement is significantly more expensive.
