The most important decision in any gate project is who installs it. Surrey has a good supply of specialist gate installation firms, but it also has a larger number of general builders, landscapers, and groundwork contractors who take gate work when it comes their way. These are not interchangeable. A specialist firm that installs gates every working day has a depth of experience that a generalist doing its fifth gate job cannot match, and the difference shows in the outcome.
Specialisation is the Primary Filter
Ask directly how many residential gate installations a firm completes in a year. Fewer than twenty suggests gate work is supplementary to another trade. Fifty or more indicates genuine specialisation. A specialist firm knows the Surrey Hills planning requirements, the chalk and greensand foundation conditions in the North Downs, the motor specifications appropriate for the heavy wrought iron gates common in the premium Surrey market, and the BS EN 12453 commissioning process in detail.

Insurance, Safety Standards, and Warranties
Public liability insurance of at least £2 million is required before any site visit is booked. Ask for the current certificate. BS EN 12453 compliance must be documented at handover. Written warranties on gate structure and automation separately. Any firm that cannot confirm all three before being shortlisted should not be shortlisted.
The Site Survey as a Quality Indicator
A reputable installer insists on a site survey before quoting. This is an engineering assessment, not a sales visit. The installer measures the opening, checks clearances, assesses ground and foundation conditions, reviews power supply routing, and discusses design options in the context of your specific property and any planning constraints. An installer who quotes without a site visit has not done this assessment and cannot provide a reliable price.
What a Quality Quote Includes
Gate fabrication or supply, groundwork, motor and control board, safety sensor equipment, and access control all itemised separately. Motor brand and model specified. Surface treatment confirmed as hot-dip galvanising plus powder coat for any steel installation. Warranty terms for gate and automation stated separately in writing.
