Automating gates you already have
If your gates and posts are sound, adding motors, a control board, safety devices and remotes is usually the cheapest route to electric gates. As a guide, automating an existing pair of gates in Surrey typically runs from about £3,000 to £10,000 or more. That depends on the gates' size and weight, the type of motor, the groundworks and how far power has to be run.
New gates and automation together
A complete new installation costs more, because the gates themselves are a big part of the price. Aluminium and timber gates vary widely, and bespoke wrought-iron or oak gates for large properties cost considerably more. Get several written quotes that list the gates, motors, safety devices and any groundworks separately.
What changes the price
- Swing or sliding: sliding gates need a track and foundation; swing gates need room to open
- Underground motors cost more to fit than ram or arm motors
- Distance from the house for power and intercom cables
- Intercoms: from a simple keypad to video and smartphone control
- Slopes, drainage and planning requirements
Budget for running costs too
- An annual service, typically around £150 to £300 plus VAT for a pair of swing gates
- Occasional repairs: photocells, remotes and control boards wear out
- Motor replacement after 10 to 15 years
- A little electricity, plus a back-up battery if you want the gates to work in a power cut
Make sure it's done safely
Automated gates must be installed to current safety standards, including force testing and the right safety devices. The cheapest quote is not a bargain if the gate isn't safe. Ask installers how they test and certify their work, and for the paperwork afterwards.
