This is the question we get asked on more site surveys than almost any other. A homeowner has decided they want electric gates. They have seen both types on neighboring properties or online. They want to know which one is right for their driveway. And the honest answer which we will give you in this guide is that for most London driveways, the site itself answers the question rather than personal preference.
Swing gates and sliding gates are both reliable, widely installed products that work well when they are matched to the right site. Choosing the wrong one for your driveway does not just affect how the gate looks. It affects how it functions every day, how much it costs to maintain, and whether it causes problems with vehicles, neighbours, or the highway authority further down the line.
This guide covers the practical differences between swing and sliding gates, what each type costs in London in 2026, which properties suit which system, and the situations where one option is simply not viable regardless of what you might prefer.
The Core Difference: How Each Type Opens
Swing gates are hinged at the post and open by rotating inward or outward, like a large door. A pair of swing gates has two leaves, each attached to a post on the boundary, meeting in the middle when closed. They require clear space in the direction they open either behind the gate on the driveway, or in front of it toward the road, depending on the configuration.
Sliding gates move horizontally, parallel to the boundary, rather than swinging in either direction. They run along a track in the ground or hang from a cantilever beam. When the gate opens, it disappears to one side of the entrance. The gate itself needs to be as long as the opening is wide, plus additional length for the run-back section. A 4 metre opening needs a gate of roughly 5 to 6 metres in total length to allow for adequate run-back.
That difference in how they open is what determines which type suits your specific driveway.

When Swing Gates Are the Right Choice
Swing gates are the right choice for the majority of London residential properties, and there are good reasons why they account for the larger share of what we install across SW and KT postcodes.
The driveway has sufficient depth: Inward-opening swing gates need enough space behind the gate line for the leaves to open fully without hitting a parked car or the garage door. For a pair of standard residential swing gates at 4 metres wide, each leaf is 2 metres long. They need approximately 2.2 to 2.5 metres of clear driveway depth to open comfortably. Most Victorian, Edwardian, and interwar properties across Wimbledon, Richmond, Kingston, and Putney have driveways that comfortably accommodate this.
The driveway is level or close to level at the entrance: Swing gates work well on flat ground or on driveways with a gentle slope away from the gate. The geometry of a hinged gate is straightforward on flat terrain and the motor operation is reliable.
The entrance is not immediately adjacent to the pavement: Outward-opening swing gates require space in front of the gate line, which means the gate swings over the public pavement when opening. Under the UK planning portal guidance on gates and fences, outward-opening gates that encroach on the public highway can cause problems with the highway authority. Inward-opening gates avoid this entirely.
The aesthetic is traditional: For period properties across South West London Victorian terraces in Clapham, Edwardian semis in Putney, Georgian frontages in Richmond, a pair of swing gates with vertical steel infill reads as sympathetic to the architecture in a way that a single large sliding panel often does not.
The budget is more constrained: Swing gate installations are generally less expensive than equivalent sliding gate installations because the groundwork is less complex, the motor is simpler, and there is no track to install and maintain.
When Sliding Gates Are the Right Choice
Sliding gates solve specific problems that swing gates cannot. There are London driveways where a sliding gate is the only sensible answer, and trying to fit swing gates on them causes problems.
The driveway is too short for swing gates to open inward: This is the most common reason we specify sliding gates on London sites. A driveway that is 1.5 metres deep from the gate line to the garage door simply cannot accommodate inward-opening swing leaves. A sliding gate has no depth requirement at all. The gate moves sideways and the driveway space is fully available for parking right up to the gate position.
The driveway slopes significantly toward the road: A swing gate on a driveway that falls sharply toward the road faces a clearance problem. As the gate swings open, the bottom edge of the gate leaf descends toward the ground. If the ground is rising toward the gate as it opens, the gate catches or drags. This can be managed with careful geometry on gentle slopes but becomes increasingly problematic as the gradient increases. A sliding gate moves horizontally regardless of the ground gradient and avoids the issue entirely.
The entrance is directly off a busy road and outward opening is not viable: For properties in London where the driveway entrance is immediately on a main road, having swing gates that open outward into passing traffic is not safe. A sliding gate opening laterally along the boundary is the correct solution.
The property needs more side space than depth: Some London properties particularly corner plots, end-of-terrace houses with a side return, and properties with wide frontages have more space along the boundary than into the site. For these, a sliding gate uses that side space efficiently.
Security is the primary driver: Sliding gates, when closed, lock into a cradle fitting that makes them significantly harder to force than swing gates. For security-focused installations in commercial properties, high-value residential, or properties with a previous security incident the inherently stronger closure point of a sliding gate is a genuine advantage.
Motor Systems: What Each Type Uses
The motor is the heart of any electric gate installation, and the choice of gate type directly affects which motor system is appropriate.
Swing Gate Motors
Above-ground articulated arm motors are the most widely used system for residential swing gates. The motor sits on the inside face of the gate post and operates the gate via a mechanical arm connected to the gate leaf. They are reliable, straightforward to service, and the most cost-effective option. Motor kits for a pair of residential swing gates typically cost £900 to £1,800.
Underground motors are buried beneath the hinge post and completely invisible from outside the property. The gate appears to open on its own with no visible mechanism. These are popular on premium London properties in Richmond, Wimbledon Village, and Kingston Hill where a clean gate post face is a priority. Underground motor kits cost £1,500 to £3,000+ and require more involved groundwork during installation.
Sliding Gate Motors
Track motors run along a steel channel set into the ground parallel to the boundary. A rack gear on the underside of the gate engages with the motor drive. They are effective on flat, well-drained sites. Track motors are vulnerable to debris accumulation in the channel, which is worth bearing in mind on sites with mature trees and leaf fall.
Cantilever motors suspend the gate from a beam without a ground track. The gate hangs and rolls on wheels that run on the beam, with a counterbalance section extending behind the post. Cantilever systems are more expensive than track systems but work on uneven or soft ground where a buried track would be problematic. For London properties near the Thames or on softer alluvial ground, cantilever is often the better specification.
Cost Comparison: Swing Gates vs Sliding Gates in London
Sliding gates consistently cost more than swing gates for an equivalent installation. The difference varies depending on the spec, but as a general rule a sliding gate installation runs 20 to 40 percent higher than a comparable swing gate installation on the same site.
| Installation Type | Swing Gates (London 2026) | Sliding Gates (London 2026) |
| Standard electric, residential | £4,500 to £8,500 | £6,500 to £11,000 |
| Bespoke fabricated, residential | £7,000 to £13,000 | £9,000 to £16,000 |
| Underground motors (swing only) | Add £1,500 to £3,000 | N/A |
| Cantilever system (sliding only) | N/A | Add £1,500 to £3,500 |
The cost difference comes from three factors. The gate itself needs to be longer for a sliding installation. The groundwork is more complex whether for a track channel or cantilever post foundations. And the motor system is more powerful and more expensive than most residential swing gate motors.

Maintenance: What to Expect After Installation
Both gate types require annual servicing, but the nature of the maintenance differs.
Swing gates need lubrication of hinge pins and motor arm pivot points, a check of motor force settings, safety edge and photocell testing, and inspection of the gate leaf fixings. A well-installed swing gate on good post foundations with an above-ground motor is a low-maintenance product. Annual servicing typically costs £100 to £200 from a professional gate company.
Sliding gates need everything a swing gate needs, plus track cleaning and roller inspection. Debris in the track channel is the most common cause of sliding gate issues. Leaves, grit, and standing water in the channel all affect performance over time. On London sites with mature trees near the boundary, track maintenance is a genuine ongoing consideration. Cantilever systems avoid the track issue but need roller and beam inspection instead.
Under HSE guidelines for powered gate installations, both swing and sliding electric gates must be fitted with safety photocells, safety edges, and a force compliance test before handover. These are legal requirements on both gate types, not optional extras.
What About Bi-Fold Gates?
Bi-fold gates are worth a mention as a third option for London driveways where neither swing nor sliding is straightforward.
A bi-fold gate folds in half as it opens, halving the swing clearance required compared to a standard swing gate. A 4-meter bi-fold gate needs roughly 1.2 meters of swing clearance rather than the 2.2 to 2.5 meters a standard swing gate requires.
They are more mechanically complex than swing gates and more expensive, typically starting from £8,000 installed. They also have more moving parts and more potential failure points than either of the simpler systems. For most London driveways, if swing gates fit, swing gates are preferable. Bi-fold gates earn their cost on sites where the driveway depth falls between what swing gates need and what would justify a full sliding gate installation.
The Site Survey: Why It Matters More Than the Comparison Table
Everything in this guide applies in general. What applies to your specific property can only be determined by looking at it.
A site survey establishes the exact opening width, the available driveway depth, the ground gradient at the entrance, the proximity of any obstacles including trees, drainage features, or utility covers, the distance from the consumer unit for electrical cabling, and the ground conditions for post foundations. Every one of these affects the gate specification, and a quote given without a site survey is a guess rather than a price.
At NOVA Steels, the free site survey covers all of this and provides a written quote with a clear recommendation on gate type based on your specific site rather than a general preference.
