Short answer: a 6ft solid-panel fence is the practical way to get privacy in a UK garden — it blocks sightlines, cuts wind, and makes a patio feel enclosed. It will not soundproof your garden: real noise reduction needs mass and height that domestic fencing doesn't have. Below is what a privacy fence genuinely does, and how to choose one.

What "privacy" actually means in a garden

Three different problems get lumped together under privacy, and they have different answers.

• Being overlooked at ground level — neighbours, passers-by, the patio next door. A solid 6ft fence solves this well.
• Being overlooked from above — upstairs windows, a house on higher ground. No fence solves this; planting, pergolas or sail shades do.
• Noise — traffic, a busy road, neighbours. Fencing helps far less than people hope. More on this below.

Being clear about which one you're actually solving prevents the most common disappointment: spending on a tall fence and finding the upstairs window opposite still looks straight into the garden.

Privacy panel styles

Tongue-and-groove (solid)

Boards that interlock into a continuous solid surface — no gaps, no sightlines, maximum screening. This is the choice where the point is simply not being seen: hot tubs, patios, boundaries against a busy footpath.

Lattice-topped

The same solid lower panel, finished with an open lattice section along the top. It keeps privacy where you sit while letting light and air through above, and it softens the appearance of a tall boundary — a 6ft solid wall of fence can feel oppressive in a small garden, and the lattice takes that weight off.

Both are available in our Cascade privacy range, supplied 8ft wide × 6ft high, on 5×5in posts with matching caps.

The honest truth about noise

This deserves a straight answer, because a lot of fencing marketing implies more than it delivers.

Sound is blocked by mass — the heavier and denser the barrier, the more it stops. Fence panels of any domestic material are light, and sound also travels over the top of them, so what you get from a standard 6ft fence is a modest reduction in direct noise plus a psychological improvement from no longer seeing the source. That's genuinely worth something, but it is not soundproofing.

What actually reduces noise meaningfully:

• Mass and height — a masonry wall, or a purpose-built acoustic barrier with a specified dB reduction. These are specialist products and priced accordingly.
• No gaps — sound leaks through openings, so a solid, continuously sealed barrier outperforms a gappy one. Tongue-and-groove beats lattice-topped here.
• Distance and masking — planting, water features, and simply moving your seating area often do more for perceived noise than a taller fence does.

If your priority is genuinely a decibel reduction from a main road, you want an acoustic barrier specialist rather than garden fencing — from anyone. If your priority is not being overlooked, with some wind shelter and a calmer-feeling garden, a solid privacy fence is exactly right.

Wind, shelter and the thing people forget

A solid 6ft fence is a large sail. In an exposed garden, wind load is the main structural consideration, and it's why posts and their fixing matter more on privacy fencing than on any other style.

Our privacy panels are carried on 5×5in posts rather than the 4×4in used for picket and pool ranges — the bigger section is there because the panels catch more wind. Set them properly, and on hard surfaces use the correct steel mounts rather than improvising.

Gardeners sometimes note that a totally solid barrier creates turbulence on the leeward side, while a partially permeable one filters wind more gently — one more reason lattice-topped panels suit exposed sites.

Height, planning and neighbours

In the UK you generally need planning permission for a fence over 2m (about 6.5ft), or over 1m where it fronts a road or footpath. Conservation areas, listed buildings and estate covenants can tighten this further. Our privacy panels at 6ft sit inside the usual domestic limit, but check locally before you order if you're near a boundary with a highway.

Two practical points that save arguments: confirm which boundary is actually yours before replacing anything, and remember the "good side" convention — the finished face traditionally goes towards the neighbour. Neither is a legal rule in every case, but both are worth settling before delivery day rather than after.

Why PVC-U for a privacy fence

Privacy panels are the largest surface area of any fence style, which magnifies whatever the material does over time.

A 6ft timber screen is a lot of square metres to re-treat every couple of years, and it's the style where warping and greying show most obviously — a solid panel telegraphs every twisted board. PVC-U doesn't rot, warp or splinter; the colour runs through the material, so there's no repainting cycle across all that area; and it washes clean rather than needing sanding and re-staining.

It also doesn't lose its shape at the base, which is where solid timber screens usually fail first.

Where privacy fencing works

Patios and seating areas — the classic case, where you want to sit without an audience.

Hot tubs and garden rooms — screening plus wind shelter.

Boundaries against footpaths or car parks — removing both sightlines and the sense of exposure.

Bin stores, oil tanks and utilities — hiding the things nobody wants to look at.

Commercial and hospitality — outdoor dining areas, staff yards, plant screening. For volume or account terms see Trade Enquiries.

What you'll need

Privacy runs are priced by panel, post, cap and gate like any other. Because the panels are 8ft wide, a long boundary needs fewer posts than the equivalent in 6ft panels — worth knowing when comparing quotes.

The Fence Planner handles the arithmetic: choose the privacy range, enter your run and any gate openings, and it returns every panel, 5×5in post, cap and gate with a live total. For how pricing works generally, see how much vinyl fencing costs in the UK.

Frequently asked questions

How tall can a privacy fence be?

Generally up to 2m without planning permission, or 1m fronting a road or footpath. Our privacy panels are 6ft high, inside the usual domestic limit — but check locally for conservation areas, listed buildings or covenants.

Does a fence block noise?

Only modestly. Sound needs mass to stop it and travels over the top of domestic fencing. A solid fence reduces direct noise a little and removes the visual source, which helps perceptually — but genuine dB reduction needs a masonry wall or a specialist acoustic barrier.

Solid or lattice-topped?

Solid tongue-and-groove for maximum screening and slightly better noise performance. Lattice-topped where you want light, air and a less imposing boundary — a good compromise in smaller or exposed gardens.

Will a 6ft fence stop people seeing in from upstairs?

No — nothing at fence height will. Planting, pergolas and shade sails are the tools for overlooking from above.

Do privacy panels need stronger posts?

Yes. They catch far more wind than open styles, which is why ours use 5×5in posts rather than the 4×4in used for picket and pool fencing.

Do you install it?

No — supply-only. We deliver or you collect; your own contractor or team installs. If you need someone, see find an installer.
