What do you need?
One installer for the deck and everything around it.
- Composite decking
No rot, no splinters, no staining. Lasts decades on a good frame.
- Timber decking
Softwood or hardwood. Lower upfront cost, a little care each year.
- Composite fencing
Panels that match the deck and never need painting.
- Pergolas
Shade, lights and climbers over a deck or patio.
- Verandas
A glass roof off the back of the house.
- Glass balustrades
A safe edge for raised decks that keeps the view.

Decking on a Sheffield slope
Plenty of Sheffield gardens drop away from the house or climb up behind it. Decking is often the easiest way to make that ground usable: the frame does the levelling, so there is no need to dig out and retain the bank.
- Gentle slope: adjustable supports take up the difference, with a step down at the low edge.
- Steeper slope: a raised deck on posts, with steps and a balustrade.
- Terraced garden: two or three decks at different levels, linked by steps.
Tell the installer about the slope when you ask for a quote. The form asks.
Planning, in short
Most decking needs no planning permission. The limits are that it is no more than 30 cm above the ground and that, together with any extensions and garden buildings, it covers no more than half the garden.
A deck raised more than 30 cm counts as a raised platform and usually needs planning permission. So do verandas. Listed buildings and conservation areas have tighter rules.
How decking gets fitted
From the first visit to the finished deck, most jobs take two to five days on site.
Survey and fixed price
The installer measures, checks the ground, drainage and access, and helps you choose boards.
Clearing and groundwork
Old decking, turf or paving removed, the ground levelled and a weed membrane laid.
The frame
Joists set level on supports or posts. On a slope, this is where the height is made up.
Boards and edges
Boards fixed, fascias and edging fitted, with steps where the levels change.
Finishing
Balustrades, lighting, a pergola or planters. Most decks take two to five days on site.

Questions people ask
How much does decking cost in Sheffield?
Installed composite decking typically costs £100 to £200 per square metre and treated softwood £60 to £130. A 15 m² composite deck is usually £1,500 to £3,000. Try the decking cost calculator.
Composite or timber decking?
Timber costs less to fit and feels natural but needs treating every year or two. Composite costs more but needs little more than a wash. Read composite vs wood decking.
Do I need planning permission for decking?
Not usually, if it is no more than 30 cm above the ground and, with other extensions and buildings, covers no more than half the garden. Raised decks and verandas usually need permission. Read planning permission for decking.
Can you build decking on a sloping garden?
Yes. The frame is built level on adjustable supports or posts, with steps and a balustrade where the drop gets bigger. It costs more than a deck on flat ground.
How long does it take to fit decking?
Most decks take two to five days on site, depending on size, groundwork and extras like steps and balustrades.
When is the best time to build decking?
Spring and summer are busiest, so book early. Decking can be fitted most of the year if the ground is not frozen or waterlogged.
