The short answer
For garden privacy, a solid-board fence — closeboard (feather-edge) or a good solid panel — at around 1.8m (6ft) gives the most complete screening. Closeboard is the strongest and most private, with dense vertical boards and no see-through gaps. Solid lap or composite panels also screen well. For exposed gardens, a hit-and-miss design keeps privacy while letting wind through. Remember that in most of the UK a rear-garden fence can be up to 2m high without planning permission (lower next to a highway), so trellis or planting is often the way to add height. Pair privacy with strong posts so a tall, solid fence does not blow down.
Privacy is the most common reason people replace a fence, but the most private panel is also the one that catches the most wind. The best privacy fence balances complete screening with a design and height that will actually stand up.

What makes a fence private
A privacy fence needs to do two things: block the line of sight completely, and be tall enough to screen people standing or sitting nearby. The most private fences are solid, with boards butted or overlapped so there are no gaps to see through.
- Closeboard (feather-edge): dense, overlapping vertical boards on solid rails, with no see-through gaps and great strength. This is the most private and durable timber option.
- Solid lap / overlap panels: the common garden panel; good privacy when new, though thin slats can shrink and open small gaps over years.
- Composite panels: solid, uniform boards that screen completely and stay consistent, with no shrinking gaps.
- Hit-and-miss: boards staggered front and back block the head-on view almost like a solid fence, while still letting air through — a good choice if the garden is exposed.
Height rules you need to know
Privacy usually means height, and height is where UK rules come in. As a general guide under permitted development in England and Wales, a fence in a rear garden can be built up to 2 metres high without planning permission. Where the fence is next to a highway used by vehicles (typically a front boundary), the limit is generally 1 metre. Going above these heights usually needs planning permission, and there can be local and listed-building exceptions, so check with your local planning authority before building tall.
This matters because a standard 1.8m (6ft) fence screens most direct views but may not block an overlooking upstairs window or a raised neighbouring garden. Rather than building an unlawfully tall fence, the usual solution is to add a trellis top (which counts towards the overall height) with climbing plants, or to plant a hedge or tall shrubs behind the fence for extra screening that is not limited in the same way.
| Fence type | Privacy | Notes |
|---|---|---|
| Closeboard / feather-edge | Highest | Solid, strong, no gaps |
| Composite solid panel | High | Uniform, no shrinking gaps |
| Solid lap / overlap | Good | May gap slightly with age |
| Hit-and-miss | High head-on | Lets wind through too |
| Slatted (open) | Low–moderate | Decorative; see-through at angles |

Don't sacrifice strength for privacy
The catch with privacy fences is that the most solid panel is also the biggest sail. A tall, fully solid fence on weak or shallow posts is the classic storm casualty. To get privacy that lasts:
- Use strong posts: concrete posts do not rot and hold a tall, heavy fence far better than timber. A concrete gravel board keeps the panel base off wet ground.
- Set posts deep in concrete: taller, solid fences need deeper, firmer foundations to resist the extra wind load.
- Consider hit-and-miss in exposed gardens: if your boundary catches the wind, a hit-and-miss design keeps near-solid privacy while letting air through, so the fence is far less likely to be blown flat.
Privacy from above, gaps at the base, and the neighbourly bits
Eye-level screening is only part of privacy. The two places it commonly leaks are above the fence and below it. Overlooking comes mostly from upstairs windows and raised or terraced gardens, where a standard 1.8m fence does little — the honest fix there is planting: a tree, tall shrubs or a hedge behind the fence reaches higher than a fence legally can and softens the view from above without acting as a solid sail. At the base, a gap under the bottom rail or between the panel and a sloping ground line can leave a surprising sight line for anyone close to it, as well as letting pets through; a gravel board both closes that gap and keeps the panel off wet ground.
Privacy also has a neighbourly and a legal side worth getting right. On a shared boundary, the finished (smooth) face of a fence is conventionally turned to face outward towards the neighbour, with the posts and rails on the owner's side — so a fence built the other way around gives your neighbour the framework view and you the flat face. Before raising height for privacy, it is worth a conversation, since a sudden tall fence can sour relations and, in extreme cases, a very high evergreen screen can fall under high-hedge rules. And privacy is two-way: a fence that screens you also screens your neighbour, which is usually welcome but worth bearing in mind for light and sight lines on both sides.
None of this changes the core choice of a solid panel at sensible height on strong posts, but it explains why two identical fences can feel very different: one closes the gaps top and bottom and faces the right way, the other leaves a view over the top, a gap at the base, and the rails on the wrong side.
Choosing the right privacy fence
Match the fence to your garden and how much screening you need:
- For maximum privacy and strength: closeboard at around 1.8m on concrete posts with a gravel board — the most durable solid option.
- For a low-maintenance solid screen: composite panels, which screen completely and never need treating, at the cost of a higher price.
- For an exposed garden: hit-and-miss, which keeps privacy while surviving wind that would flatten a solid panel.
- To add height to an existing fence: a trellis top with climbing plants, or hedging behind, rather than an over-height solid fence.
The best privacy fence is the one that screens fully and stays standing. For most UK gardens that means a solid closeboard or panel fence at the standard height, on strong posts, with trellis or planting to top up screening where an overlooking window or raised garden needs it. Check the height rules for your boundary first, and never trade so much for privacy that the fence cannot survive the wind it now has to face.
Frequently asked questions
How high can I build a fence for privacy without planning permission?
As a general guide in England and Wales, a rear-garden fence can be up to 2 metres high under permitted development. Next to a highway used by vehicles the limit is usually 1 metre. Above these you typically need planning permission, and local exceptions apply, so check with your council before building tall.
What is the most private type of fence?
A solid closeboard (feather-edge) fence gives the most complete privacy, with dense overlapping boards and no see-through gaps, plus great strength. Solid lap and composite panels also screen well. Hit-and-miss blocks the head-on view almost as well while letting wind through.
How can I add privacy to an existing fence?
Add a trellis top with climbing plants to raise screening above eye level, or plant a hedge or tall shrubs behind the fence. Trellis counts towards your permitted height, so keep the total within the limit for your boundary. These options add height without building an unlawful solid fence.
