Short answer: timber is cheaper to buy; vinyl is cheaper to own. A treated timber fence needs painting or staining every year or two and typically needs replacing within a decade. White PVC-U needs washing and nothing else. If you want the painted-timber look without the painting, vinyl wins — and that's the trade most of our customers are making.
Vinyl vs timber at a glance
| Vinyl (PVC-U) | Treated timber | |
|---|---|---|
| Upfront cost | Higher | Lower |
| Ongoing upkeep | Wash occasionally | Treat, stain or paint every 1–2 years |
| Rot & insects | Immune — no organic content | Vulnerable, especially at the post base |
| Warping & splintering | No | Common as it weathers |
| Colour | Runs through the material | Surface coating that fades and flakes |
| Typical service life | Decades | Often under a decade |
| Weight | Light and easy to handle | Heavier, especially when wet |
Understanding what you're comparing
Timber fencing is a natural product: sawn softwood, usually pressure-treated with preservative to slow decay. Treatment delays rot, it doesn't prevent it — and the protection wears off, which is why timber needs re-treating on a cycle for its whole life.
Vinyl fencing is PVC-U, the same material family as most British window frames. It's extruded as one consistent material with the colour running all the way through, so there's no coating to flake and no core to expose. Panels arrive with rails and infill ready to slot between posts.
That single difference — organic versus inorganic — drives almost everything below.
Cost: the comparison that changes over time
On day one, timber wins. A treated timber panel is usually cheaper than a PVC one, and for a large boundary that gap is real money.
Our white PVC picket panels start at £84.95 for 2.5ft and 3ft heights and £95.95 for 4ft, with posts, caps and gates priced separately. You can price a complete run in the Fence Planner.
The picture shifts as soon as you count the years. A timber fence carries a running cost that a vinyl fence simply doesn't: preservative or paint every year or two, the time to apply it, replacement panels when one warps, and new posts when the bases rot. Add early replacement of the whole fence and the "cheaper" option frequently overtakes vinyl well inside its lifetime.
The honest way to compare is cost per year of service, plus the weekends you'd rather not spend with a brush.
Durability in the British climate
Our weather is the problem timber has to survive: persistent damp, freeze-thaw cycles, and long grey spells that keep everything wet.
Timber absorbs moisture, and absorbed moisture is what causes swelling, warping, splitting and eventually rot. The most common failure point is where the post meets the ground — wet, airless, and exactly where fungi thrive. That's why so many timber fences fail at the base while the panels above still look serviceable.
Vinyl has nothing for damp to attack. It won't rot, warp, splinter or rust; the freeze-thaw cycle doesn't trouble it; and because the colour is integral, a scrape doesn't reveal bare material underneath. There's no paint layer to blister and no preservative to reapply.
Maintenance: an honest account
"Low maintenance" is claimed by everyone, so here is what each actually asks of you.
Timber: clean down and re-treat or repaint on a one-to-two-year cycle. Replace the occasional warped board or rotten post. Check fixings as they corrode. It's not difficult work — it's just work, repeatedly, for as long as you own the fence.
Vinyl: wash with mild soap and water when it looks dirty. Green algae on a shaded run wipes off. That's the whole list. No painting, no staining, no sanding, no sealing.
White PVC does show dirt more readily than a dark-stained timber panel — but it also cleans back to like-new in minutes, which stained timber doesn't.
Appearance
Timber's appeal is genuine: natural grain, and the ability to stain it any colour you like. Its weakness is that this appearance is a surface treatment with a short shelf life — it fades, greys and flakes, and restoring it is the maintenance cycle above.
Vinyl gives you the crisp painted-timber look permanently. Bright white picket for a front garden, taller panels for boundaries, post-and-rail for paddocks, close-boarded or lattice-topped panels for privacy. It stays looking cared-for without being cared for — which, for a front boundary that everyone sees, is the point.
If you want visible natural grain, timber (or composite) is the honest answer. If you want a clean, uniform, always-tidy line, vinyl.
Installation and handling
We're supply-only — your team or contractor installs — but the material affects the job either way.
Vinyl panels are light enough for two people to handle comfortably, and the system assembles rather than being cut and nailed: panels slot into routed posts, so a straight run goes up quickly and cleanly. Posts are concreted in, or fixed to concrete and paving with steel surface mounts so there's no digging at all.
Timber is heavier — considerably so when wet — usually needs more cutting on site, and relies on fixings that will themselves corrode over time.
Environmental considerations
Timber is renewable and biodegradable, which is a real advantage. Set against it: the preservatives and paints applied over its life, and the replacement cycle, both carry an environmental cost that's easy to overlook.
Vinyl isn't renewable, but it lasts for decades without any chemical treatment at all, and PVC-U is widely recyclable at end of life. The greenest fence is generally the one you don't replace or re-treat — which is where a long-life material earns its place.
Which should you choose?
Choose timber if the upfront budget is the binding constraint, you want visible natural grain, or you actively enjoy changing the colour of your fence.
Choose vinyl if you want a fence that looks smart for decades with almost no effort, you're tired of the treating cycle, you're fencing a front boundary where appearance matters, or you want a pool, paddock or privacy fence that won't rot at the base.

Frequently asked questions
Is vinyl fencing more expensive than wood?
To buy, usually yes. To own, usually no — timber's treatment, repairs and earlier replacement generally close the gap within a few years and then overtake it.
Does vinyl fencing look cheap?
Good PVC-U fencing is designed to reproduce the painted-timber look, and it keeps that look far longer than paint on wood does. It won't imitate natural grain — if grain is what you want, timber or composite is the honest choice.
How long does vinyl fencing last?
Decades, in normal domestic use — which is why our residential range carries a limited lifetime warranty (details).
Can I replace timber panels with vinyl ones?
Usually yes, as a complete system — vinyl panels are designed to work with matching vinyl posts rather than dropping into existing timber posts. The planner will tell you exactly what a replacement run needs.
Does vinyl fencing become brittle in cold weather?
Modern PVC-U fencing is formulated for prolonged outdoor exposure in climates like ours and handles UK winters without difficulty.
