The installer matters more than the gate. Two firms can fit the same motor to the same gate, and one will hand over a safe, certified machine while the other leaves a hazard at the end of your drive. In Kent there is a recent reminder of the stakes: in April 2025, Kent Trading Standards secured the prosecution of a Tonbridge gate firm after a 400 kilogram sliding gate it had installed fell and crushed a homeowner, causing life-changing injuries. A plain guide roller had been used where a proper travel stop was needed. The company was fined £30,000 plus costs.
An Automated Gate Is a Machine
The Health and Safety Executive treats powered gates as machinery. When a gate is first put into service, it falls under the Supply of Machinery (Safety) Regulations 2008, and the installer who automates it takes on the duties of a manufacturer. HSE is clear that every customer is entitled to comprehensive user instructions and a Declaration of Conformity in English, and that the gate should carry conformity marking.
HSE also explains that health and safety law does not place duties on householders with private gates, but anyone who works on the gate has duties, and householders may be sued for any harm or damage their gate causes. Choosing a competent installer is how you avoid inheriting a problem.
Looking for a Kent gate installer?
Up to three Kent installers will arrange a site survey and a written quote. No fee and no obligation.
Look for Gate Safe Training
Gate Safe is a registered charity set up in 2010 after two children were killed by automated gates, and it is based in Elham, near Canterbury. It trains installers and keeps a register of those who have completed its course, with more than 3,000 listed. You can search the register by postcode. Gate Safe is open that it cannot audit every installer on the list, so treat registration as a good sign rather than a guarantee, and still check the paperwork described below.
Gate Safe's own surveys suggest that around nine in ten gates are unsafe, and that an estimated 300,000 new automated gates are installed every year. Whatever the precise figure, the scale of the problem is why training matters.
DHF Membership and Training
The Door and Hardware Federation is the trade body for the powered gate industry, and it publishes the code of practice installers work to. Jacksons, the Kent gate manufacturer, puts it simply: if an installation is cheap, there could be a reason, so make sure the installer is DHF trained. DHF members also give you access to the federation's dispute resolution route if something goes wrong.
Kent Trading Standards Checked
Kent County Council runs Trading Standards Checked, a fair trader scheme for home improvement firms. Members are vetted before joining and complaints are monitored throughout their membership. Gate installers are not a category of their own, so search the listing by name, and treat membership as a further reassurance alongside gate-specific training rather than a substitute for it.
Experience With Automated Gates
A builder who has fitted a few manual gates is not the same as a gate automation specialist. One BuildHub member warned against getting a builder to fit an automated gate unless they had done them before, and another pointed out that because electric gates are a safety matter, any installer needs good insurance. Ask for references from automated gate jobs, not general building work, and ask to see the public liability insurance certificate.
Safety Edges Are Not Optional
A gate needs protection that stops it hurting someone it touches. That means pressure-sensitive safety edges or a motor with force limitation, checked with a force testing meter, backed up by photocells. The DHF warns that a single light beam is far too easy to defeat to rely on alone. On PistonHeads in February 2026, an experienced poster noted that safety edges are not cheap but are essential for a legal installation, and that many installers break the law by leaving most of the safety systems out. If a quote has no safety edges and no force test, ask why.
The Paperwork You Are Entitled To
At handover you should receive a Declaration of Conformity, a conformity plate fixed to the gate, user instructions, the risk assessment, force test results and a maintenance log book. The electrical supply should come with its own certificate from the electrician. If an installer is vague about any of these before you sign, that tells you something. A good firm will happily show you an example pack from a previous job.
What a Good Quote Looks Like
A good quote is itemised, so you can see the gate, posts, motor model, safety devices, access control, electrical work, labour, testing and VAT separately. It should be based on a site visit. Mumsnet posters describe installers who promised to come and measure and never turned up, which is a fair early filter: a firm that cannot keep a survey appointment is unlikely to keep an installation date. A total far below what Kent homeowners actually pay usually means something has been left out.
Deposits and Paying Safely
Bespoke gates often need a deposit so the installer can order materials. Keep it modest and pay it by credit card where you can: under section 75 of the Consumer Credit Act 1974, the card company shares responsibility for purchases with a cash price between £100 and £30,000, which covers most gate jobs. Agree stage payments tied to delivery, groundwork and commissioning, and hold the final payment until the gate has been force tested and the paperwork handed over.
Questions to Ask Every Installer
Ask whether they have Gate Safe or DHF training, and how many automated gates they fitted last year. Ask which motor brand they use and whether they carry spare parts. Ask how they will protect the closing edge and the hinge side, and whether they force test at handover and at every service. Ask what paperwork you will receive, and what a service plan costs afterwards. A good installer answers all of these without hesitation; one who cannot is not the firm to trust with a machine at the end of your drive.
Finally, ask how they would handle your specific site. A good answer mentions your slope, your ground, how power will reach the gate and how a car will wait off the road. Installers who know Kent will raise local issues, such as conservation area rules in Tonbridge or salt air on the coast, before you do. An automated gate system is only as good as the person who designs and commissions it.
If Something Goes Wrong After Installation
Start with the installer, in writing, and refer to the paperwork and warranty terms you were given. If the firm is a DHF member, the federation offers a dispute resolution route. If you think the gate is unsafe, Gate Safe has a form for raising concerns about an installation, though it is clear that it is not an enforcement body. Unsafe machinery is a matter for Trading Standards, and the 2025 Kent prosecution shows that Kent Trading Standards will act where a gate has been installed dangerously.
If you paid part of the price by credit card, you may also be able to claim from the card company under section 75. Keep every quote, invoice, email and photograph from the start of the job, because a clear record makes any of these routes far easier.
