Exterior Wall Cladding Panels UK: Colours, Sizes & Where to Use It
Exterior cladding gets asked to do two jobs at once: survive UK weather for years without upkeep, and actually look good doing it. Timber does neither well long term, it needs re-staining and it warps. This guide covers what to know before choosing exterior wall cladding, the colours and sizes available, and where each one makes sense, with real panels from our Exterior Wall Cladding collection as examples.
What Is WPC Exterior Wall Cladding?
WPC stands for wood plastic composite, a blend of wood fibres and plastic that's moulded into cladding boards. It gives you the look of timber grain without timber's weaknesses: WPC cladding doesn't rot, warp, or split, and it's UV-treated to resist fading from direct sun. It also doesn't need painting, staining, or sealing at any point, an occasional wash with water is enough to keep it looking right.
Panel Sizes: 180cm vs 290cm
Most of our exterior panels come in two lengths, and the right one depends on the wall you're covering.
- 290cm panels cover more wall per panel, meaning fewer joints across a long, continuous run like a house facade or boundary wall. Fewer joints means a cleaner finish and less cutting on site.
- 180cm panels are easier to handle alone and suit shorter runs, like a balcony front, a single feature wall, or garden room sides where a full 290cm board would just get cut down anyway.
If you're covering anything over about 2.5m in one continuous section, 290cm panels usually work out more efficient. Under that, 180cm is simpler to work with.
Colour Options
All six finishes use the same WPC construction and sizing, so the choice comes down to what suits the property.
Oak and Light Brown read as classic timber tones and suit period or traditional-style properties. Dark Grey and Black give a more architectural, modern finish, popular for new-build facades and garden rooms. Khaki and Dark Brown sit in between, natural enough for a garden setting without looking rustic.
Where Exterior Cladding Works Best
- House facades and exterior walls
- Garden feature walls and boundary walls
- Balconies and terraces
- Garden rooms and outdoor offices
- Commercial and retail exteriors
Installing and Looking After Exterior Cladding
WPC panels are typically fixed onto a timber or aluminium batten frame rather than directly onto a wall, this keeps a small ventilation gap behind the panels so moisture doesn't get trapped. Beyond that, upkeep is minimal:
- Clean with water and a soft brush or cloth, a mild detergent handles any built-up grime.
- No painting, staining, or resealing needed, the colour is UV-treated into the panel itself.
- Check fixings periodically on exposed, high-wind locations, same as you would with any exterior cladding system.
Frequently Asked Questions
Can exterior WPC cladding go directly over brick or render?
It's normally fixed to a batten frame first rather than straight onto brick or render, this gives a flat, even surface to fix into and leaves a ventilation gap behind the panels.
Do I need planning permission for exterior cladding in the UK?
For most houses, re-cladding an existing wall doesn't need planning permission, but rules vary for listed buildings, conservation areas, and flats. Check with your local council before starting if you're unsure.
Which colour shows the least dirt outdoors?
Darker finishes like Black and Dark Grey tend to show less visible staining from rain and general weathering than lighter tones, though all WPC panels clean up easily either way.
