What drives the cost up or down
Existing gate suitability
Not all existing gates are strong enough to motorise. A structural check is essential — twisted, rotten, or under-built gates may need replacing rather than automating.
Cable runs
Every metre of buried cable from the consumer unit adds to labour. Long runs through paving or across lawns are the biggest hidden cost on retrofit jobs.
Safety compliance
Under BS EN 12453 every automated gate needs force testing, photocells, and safety edges. A compliant installation is 15–25% more than an unregulated retrofit and is legally required.
