Our hydraulic gate closers are self-closing gate closer kits for garden, side and pedestrian swing gates. An adjustable hydraulic valve lets you set the closing speed, so the gate shuts itself every time — smoothly and without slamming. Each set includes the closer, both mounting brackets and fixings. Orders placed Monday to Sunday before 16:00 are dispatched the same day from UK stock.

Your existing closer or brackets use M8 fittings |
You want the stronger M10 fittings, or are replacing an M10 closer |
Replacing an old closer? Match the thread size of your existing fittings. Unsure? Send us a photo and we'll confirm M8 or M10 before you order. Heavier, wider or wider-opening gate (for example a large driveway gate)? Message us first and we'll advise.
Garden Gate Closer
A garden gate closer keeps side and back garden gates shut so pets and children stay in and the gate isn't left swinging in the wind. Our closers suit wooden, metal and composite garden gates, and the soft-close action stops the gate banging against the post.
Heavy Duty Gate Closer
Built for outdoor UK weather, each heavy duty gate closer has a steel body with black powder-coated finish and a rod protector tube. For frequently used gates, the M10 version gives the strongest mounting. For a heavy wooden gate, fix brackets into solid, sound timber with screws or bolts at least 40mm long.
Automatic, Self-Closing Gate Closer
Once fitted, the closer works as an automatic gate closer with no power or wiring: open the gate and it closes itself under controlled hydraulic action. Unlike a basic spring gate closer, the hydraulic valve slows the final part of the swing, so the gate doesn't snap shut. See the full comparison: gate closer spring vs hydraulic vs self-closing hinges.
Outdoor, External, Pedestrian & Metal Gate Closers
Whether you call it an outdoor gate closer, an external gate closer or a pedestrian gate closer, our M8 and M10 sets are made for exactly this job: single-leaf swing gates used on foot, such as side gates, back garden gates and pedestrian gates beside a driveway.
-
Metal gate closer: suits steel and wrought-iron gates; bolt the brackets onto a solid, flat section of the frame.
-
Wooden gate closer: fix into solid timber with screws or bolts at least 40mm long.
-
Gate self closer and gate soft closer: the gate returns to closed on its own and slows before it shuts, so it latches without banging.
Price: complete M8 and M10 sets from £84.99, including both brackets and fixings, with free UK delivery and same-day dispatch on orders before 16:00.
How to Stop a Gate Slamming
- Check the gate swings freely — stiff or dropped hinges reduce the soft-close effect.
- Fit the post bracket and gate bracket as shown in the fitting guide.
- For a softer close, use the bracket hole nearest the post.
- Turn the adjustable valve to slow the closing speed until the gate closes gently and latches.
- Re-check fixings after the first few weeks of use.

Frequently Asked Questions
Is a hydraulic gate closer the same as a spring closer?
The terms are often used interchangeably in the UK. A traditional spring closer uses a coiled spring, while our hydraulic gate closers use a gas-filled cylinder with an adjustable valve — giving a smoother, quieter, slam-free close with a speed you can fine-tune.
What is the best hydraulic gate closer for a heavy wooden garden gate in the UK?
For a wooden garden gate up to approx. 80kg and 1.2m wide, either our M8 or M10 adjustable-valve hydraulic gate closer will do the job; the M10 has the stronger fittings. Fix the brackets into solid timber and use the valve to set the closing speed.
Will a gate closer work on a metal gate?
Yes — the closers suit metal, wooden and composite swing gates, provided the gate swings freely and is within the size and weight range above.
Do I need electricity for an automatic gate closer?
No. These are mechanical hydraulic closers: no power, no wiring, no batteries.
Can I adjust how fast the gate closes?
Yes. Turn the built-in valve to change the closing speed, and choose a different bracket hole to change the closing force.
