Installing electric gates involves choosing the right gate type for your driveway or site, building solid posts or foundations, fitting motors and safety devices, and setting up how people will open the gate. We can send a local engineer in Liverpool who can survey your entrance and install new automated swing or sliding gates for homes, apartment developments and business premises.
A good installation starts with the survey, not the brochure. The slope, width, space behind the gate, power supply and who will use it all shape the design.
Swing or sliding: which suits your entrance?
| Factor | Swing gates | Sliding gates |
|---|---|---|
| Space needed | Room behind the gate for leaves to open | Run-back space alongside the opening |
| Sloping drive | Can be a problem if sloping up from the gate | Usually handles slopes better |
| Wind | Solid leaves catch the wind | Less affected |
| Groundwork | Posts or piers; boxes for underground motors | Motor base and track or cantilever foundation |
| Typical use | Most domestic driveways | Sloping drives, tight plots, commercial sites |
The repair pages for swing gates and sliding gates explain how each type works in more detail.
Gate materials and design
Steel and wrought iron gates are strong and traditional, but need good galvanising and paint, particularly near the coast. Aluminium is lighter, doesn't rust and is easier on motors. Timber looks warm but is heavy, moves with the weather and catches the wind, so it needs stronger motors. Many modern gates are aluminium with a timber-look or solid infill, giving the appearance of wood without the weight or upkeep. Solid infill improves privacy but increases wind load, while slatted or railed designs let wind pass through. Whatever the design, it should avoid climbable features and finger traps, and gaps should be considered for safety.
What an installation involves
- Survey. Measure the opening, check levels, ground conditions, existing walls or piers and the power supply route.
- Design and quote. Agree the gate style, motor type, safety devices and access control, with a price before work.
- Groundwork. Set posts, build or reinforce piers, cast motor bases, lay track or cantilever foundations, and duct cables.
- Hang the gate. Fit hinges or rollers and guides so the gate moves freely by hand.
- Fit automation. Install motors, control board, photocells, safety edges, warning light and access devices.
- Commission and hand over. Set limits and force, carry out force testing and a risk assessment, and show you how to use the manual release.
Safety from day one
A new powered gate should be designed and commissioned with safety built in: suitable force limits, photocells covering the danger zones, safety edges where crushing or shearing points remain, and documentation of how it was set up. EN 12453 is the standard used for powered gates. Ask the engineer how they will test the gate at handover. The electric gate safety check page explains what those tests involve.
Access control options
Decide early how people will open the gate, because cabling is far easier before the drive is finished. Options include remotes, keypads, audio or video intercoms, fobs and GSM or app control, covered in detail on the gate intercom and access control page. Exit loops or sensors let vehicles leave without a remote.
Planning and practical considerations
- Gates should not open outwards over a public footpath or road.
- Planning permission may be needed in some cases, such as gates over a certain height next to a highway, in conservation areas or on listed buildings. Check with your local council if unsure.
- Leave enough room for a car to pull off the road while the gate opens, if space allows.
- Consider emergency service access on shared or commercial sites.
- Think about deliveries and visitors: a keypad or intercom saves walking out to the gate.
What affects the cost of new electric gates?
- Gate size, material and design.
- Swing or sliding, single or double leaf.
- Motor type, especially underground motors or cantilever systems.
- The amount of groundwork, pier building and cabling.
- Power supply arrangements.
- Access control and number of users.
The engineer will provide a quote after the survey.
New gates or automating what you have?
If your existing gates are sound, gate automation may be all you need. New gates make sense when the old ones are rotten, rusted through or unsuitable for motors. For an existing system that has simply broken down, start with electric gate repair. Gate installations across Merseyside are booked through the same number as our garage door specialists across Liverpool, and if you are also thinking about your garage, see garage door replacement.
Frequently asked questions
Do I need planning permission for electric gates?
Often not, but it can be required depending on the height of the gate and walls, whether they are next to a highway, and whether the property is listed or in a conservation area. Check with your local council if in doubt.
How long does an electric gate installation take?
It depends on the groundwork, gate manufacture and automation. Fitting itself is often a matter of days once the gates are made, but the engineer will give you a realistic timeframe after the survey.
Are aluminium gates better than steel?
Aluminium is lighter and doesn't rust, which is kind to motors and suits coastal areas. Steel is very strong and traditional but needs good corrosion protection. The choice often comes down to style and budget.
Can electric gates be fitted to an existing driveway?
Yes. Cables can be ducted under the drive, though this may mean cutting and making good part of the surface. Planning it alongside new driveway work is easier if that's an option.
What happens at handover?
The engineer should test the safety devices and force, explain how to use remotes, keypads and the manual release, and give you any documentation for the system.
