The short answer
In the UK, the labour to install a deck commonly works out around £40 to £80 per square metre, or roughly £150 to £250 per fitter per day, with most ground-level decks taking a small team a few days. On a typical fitted deck, labour often accounts for somewhere around a third to a half of the total cost, with materials making up the rest. The labour figure rises with groundworks, height, awkward access and complex shapes, because each adds time and skill. A simple ground-level deck on flat, firm ground is the quickest to build; a raised deck with foundations, steps and a balustrade takes much longer. Labour is usually quoted separately from materials on a detailed estimate.
When people are surprised by a decking quote, the labour line is often why. Building a deck is skilled work involving groundworks, framing and finishing, so installation is rarely a minor part of the bill.

How fitters price the labour
Decking labour is quoted in a few different ways, and it helps to know which you are looking at so quotes compare cleanly. Common approaches include:
- Per square metre: a labour rate applied to the deck area, often around £40 to £80 per m2 for installation, separate from materials. This is convenient for comparing similar jobs.
- Day rate: a charge per fitter per day, commonly around £150 to £250 each, multiplied by the days the build takes. Many fitters work in pairs.
- Fixed price for the job: a single labour figure for the whole deck, based on the fitter's estimate of the time and difficulty.
However it is presented, the labour reflects time and skill. A small, simple deck might take a pair of fitters a day or two; a raised or complex deck can take a week or more once foundations, framing, boarding and finishing are counted.
| Deck type | Indicative labour as share of total | Notes |
|---|---|---|
| Simple ground-level deck | Around a third | Quick groundworks, straight boarding |
| Larger or shaped ground-level deck | Around a third to a half | More cutting, borders, setting out |
| Raised deck with steps | Around a half or more | Foundations, framing, balustrade, steps |

What the labour actually covers
The installation charge buys more than laying boards. A typical build runs through several stages, each taking time:
- Setting out: marking the deck position, checking levels and falls, and planning the frame layout.
- Groundworks: clearing and levelling the ground, laying a membrane, and digging or placing foundations such as concrete pads or post anchors.
- Building the subframe: cutting and fixing the joists and bearers square and level — the part that decides how solid the finished deck feels.
- Laying the boards: cutting boards to length, setting consistent gaps for drainage, and fixing with screws or hidden clips.
- Finishing: fascia boards, steps, balustrade, skirting and a first treatment on timber.
- Clearing up: removing offcuts and spoil from site.
Of these, the groundworks and subframe often take the most time on a difficult site, which is why two decks of the same area can carry very different labour figures.
What pushes labour up or down
Several practical factors move the installation figure, and understanding them helps you read a quote and see where any difference between fitters comes from:
- Height: a raised deck needs taller posts, more bracing, and usually steps and a balustrade. All of this adds framing time and brings safety detailing into the build.
- Ground condition: sloping, soft or uneven ground takes longer to prepare and may need deeper foundations or a heavier subframe than flat, firm ground.
- Access: if materials and waste can be moved by machine or wheelbarrow easily, the build is quicker. Carrying everything through a house or down a narrow passage adds hours.
- Shape and detail: curves, multiple levels, picture-frame borders and inset lighting all add cutting, fitting and skilled time over a plain rectangle.
- Material: heavier boards such as hardwood or solid composite, and systems that need pre-drilling or hidden clips, take longer to fix than basic screwed softwood.
Because labour responds to all of these, the clearest quotes break out installation from materials and describe the build, so you can compare fitters on the work involved rather than a single bottom-line number.
Frequently asked questions
Is it cheaper to build a deck yourself?
Doing it yourself removes the labour cost, which can be a large share of the total, but it relies on you having the tools and skills to build a level, solid frame. Mistakes in the groundworks or subframe are the usual cause of early failure, so the saving only holds if the build is done properly.
How long does it take to install a deck?
A simple ground-level deck can take a small team a day or two. A larger, shaped or raised deck with foundations, steps and a balustrade can take a week or more. The groundworks and subframe usually take the most time, especially on sloping or soft ground.
Should labour and materials be quoted separately?
Ideally yes. A quote that splits labour from materials lets you see where the money goes and compare fitters fairly. If you only get a single bottom-line figure, ask for it to be broken down so you can check what is included in the groundworks, subframe and finishing.
