How much does decking cost?
The cost of a new deck depends on three things: the size of the area, the material you choose, and the groundwork needed to build a solid, level base. Our decking price calculator gives you a realistic starting figure for both composite and timber decking, fully supplied and installed across Bolton and the North West.
As a rough guide, fitted timber decking tends to start from around £180 per square metre, while composite decking starts from around £230 per square metre. Composite costs more upfront but is virtually maintenance-free and lasts far longer, which is why more and more of our customers are choosing it.
Composite decking
- Virtually maintenance-free — no sanding, staining or sealing
- Won’t rot, warp or splinter
- Fade-resistant colour that lasts 25+ years
- Hidden fixings for a clean, premium finish
- Higher upfront cost, lower lifetime cost
Timber decking
- Lower upfront cost
- Natural, traditional timber look
- Easy to repair board-by-board
- Needs annual treating to stay at its best
- Great value for larger areas

Is composite decking worth it compared to timber?
Composite decking costs more upfront but needs almost no maintenance, won’t rot, splinter or fade quickly, and typically lasts 25+ years. Timber decking is cheaper to install but needs regular treating and tends to have a shorter lifespan.
