How Much Does Garden Decking Cost in the UK?

The typical cost of garden decking is around £1,750 for 1 to 2 days of work. This varies depending on the materials you choose, the size of the decking, your location, and the complexity of the job.

The decking cost per m² is the most useful way to compare quotes. As a rough guide, the cost of decking in the UK starts from around £40 per m² installed for budget softwood and rises to over £170 per m² for premium materials such as IPE. The overall cost of a garden decking project will also depend on additional costs such as steps, rails, fascia boards, lighting, and waste removal.

If you already have a deck and need repairs or a full replacement, expect to pay around £165 to £495 for repairs and £90 to £180 per m² for a full decking replacement, including materials and labour.

Garden Decking Prices Per m²

One of the biggest factors affecting decking prices is the size of your deck and the material you choose. The table below shows the average installed decking cost per m² for each material, so you can compare options before committing to a quote.

If you're comparing decking prices, remember that timber and composite sit at very different price points. Softwood decking is usually the most cost-effective option, while hardwood decking and premium composite boards come with a higher upfront cost — the trade-off is that some materials require less ongoing maintenance. The table below shows typical total costs by garden size so you can compare materials side by side.

Decking Cost by Garden Size

Decking Board Prices and Supply Costs

If you're planning to install your decking yourself, you'll only need to pay for the cost of materials. The prices below are supply-only costs per metre of board, giving you a starting point before factoring in labour.

As well as the boards themselves, most decking projects will need a range of additional materials. Here's what to budget for:

Labour Cost to Lay Decking in the UK

The typical labour cost to lay decking in the UK is around £22 to £55 per m², with most installations taking 1 to 2 days to complete.

This varies depending on the size of the garden, the materials used, and how many tradespeople are on the job. A small deck of around 15m² may only take 1 day for a team of 2. A project requiring significant excavation, such as removal of weeds, shrubs, trees, or existing decking, could take more than 4 days for a larger area.

Labour rates also vary by location. In London and the South East, expect to pay toward the higher end of the range. In the North, Wales, and Scotland, rates tend to be lower.

Costs of Garden Decking Maintenance and Cleaning

The ongoing maintenance cost of your decking will depend largely on the material you choose. Timber requires the most regular attention, while composite, PVC, and Trex need very little upkeep beyond occasional cleaning.

Softwood and Hardwood

Timber decking needs regular care — clean it down, then oil or stain on a schedule that suits its level of exposure. Keep the surface clear of debris to slow algae growth. A decking cleaner costs around £6.60 to £16.50 and helps preserve the wood's natural colour. Softwood will typically need treating annually, while hardwood generally requires less frequent attention.

IPE Wood

IPE is one of the lowest-maintenance timber options, needing only an annual oil treatment to keep it in good condition. Decking oil costs around £33 for 5 litres.

Composite, PVC, and Trex

Composite decking, PVC, and Trex need very little ongoing maintenance — soap, hot water, and a soft-bristle brush a few times a year is usually enough. Unlike timber, composite boards can't be sanded back. If a board is badly gouged or damaged, it will need replacing rather than refinishing.

If your decking needs repair work, here are the typical costs to budget for:

• Damaged decking boards — £1,050
• Loose stairs — £110 to £275
• Mould and rot — £165 to £495
• Stain and seal — £7.70 per m²

These repairs can be done by a DIYer or a professional. If you're hiring someone, labour typically adds around £330 to the repair cost.

What Affects the Cost of Garden Decking?

Several factors affect the true cost of a decking project. The main ones are covered below — understanding them will help you make sense of any quotes you receive and avoid unexpected costs.

• Material choice: Timber decking is the budget route. Composite decking costs more upfront but requires less ongoing maintenance. Premium decking boards and hidden fixings will add to the total cost.
• Size of the deck: Bigger areas mean more decking boards and fixings, not to mention time. Most installers charge per m². So, area is the main driver.
• Height of the deck: Ground-level decking on flat ground is usually cheaper. A raised or elevated deck needs a stronger frame, which pushes the price up and may require additional groundwork.
• Site prep and levelling: Flat, firm ground will cost a lot less. Slopes, bumps or boggy patches can mean levelling, sub-base, or raised frames and will incur additional costs. Big reshapes? Check garden levelling costs.
• Access: Tight side paths, steps or long carries slow things down and add labour time and make delivery trickier.
• Design complexity: Simple rectangles are quickest. Curves, borders, herringbone, split levels, planters or built-in seating add hours and fixings.
• Height, steps and rails: Raised decks need beefier subframes and a lot more posts. Add balustrades, gates and steps, and the total climbs again. Raised decks need guarding and handrails — plan these early so posts and fixings are built in. Plan this at the design stage so posts and fixings are included.
• Foundations and subframe: Concrete pads, ground screws or pedestals all sit at different price points. Soft ground and heavier loads push you to stronger (and pricier) options.
• Old surfaces to remove: Lifting an old deck, patio or turf means more labour and disposal. It’s less costly if the area’s cleared before the team arrives.
• Clearing and waste: Many quotes include a basic tidy, but heavy spoil or lots of roots may need a skip or collection. If it’s not included, see garden waste removal prices and skip hire costs.
• Electrics and lighting: Uplighters, sockets, or step lights need cabling and a qualified electrician — add a little extra to the budget if you want them.
• Location and labour rates: Labour rates vary depending on where you live. In London and the South East, expect to pay toward the higher end. The team's experience level also plays a role — larger crews finish faster, but you'll pay for more hands on site.
• Finishing touches: Weed membrane, trims, fascia boards, oil or stain and tidy edging don’t cost loads each, but they do add up. So, make sure they’re listed on the quote.

Which Type of Garden Decking Is Right for Me?

The right decking material depends on your budget, how much maintenance you're willing to do, and how you plan to use the space. Here's a look at the main options.

Softwood (Pine, Spruce, Redwood, Cedar)

• Best for: Natural look on a budget.
• Installed cost: £40 to £73 per m².

Great starter choice that suits most gardens. Treat it each year and it’ll keep its colour and shape.

Pros

• ✔ Warm, classic appearance.
• ✔ Simple to cut and fix.
• ✔ Gentle under bare feet.

Cons

• ✖ Regular oiling or staining.
• ✖ Shorter lifespan than other options.
• ✖ Marks and dents show sooner.

Hardwood (e.g. Oak, Balau, Garapa)

• Best for: Long-lasting, premium finish.
• Installed cost: £62 to £108 per m².

Feels solid underfoot and looks high-end. Heavier to work with, but it pays you back with years of use.

Pros

• ✔ Tough and wear-resistant.
• ✔ Weathers to an elegant silver.
• ✔ Less movement across seasons.

Cons

• ✖ Slower to install; pre-drilling needed.
• ✖ Higher upfront cost.
• ✖ Heavier subframe requirements.

Composite (WPC)

• Best for: Low-maintenance family spaces.
• Installed cost: £90 to £135 per m².

Colour stays steady and there are no splinters. A quick sweep and rinse is usually all it needs. Usually made from environmentally friendly recycled plastic and wood.

Pros

• ✔ Minimal maintenance - no yearly staining needed.
• ✔ Neat hidden-fixing systems.
• ✔ Good slip resistance options.

Cons

• ✖ Budget composite boards can look plastic.
• ✖ Scratches are hard to disguise.
• ✖ Heavier; needs a solid frame.

PVC / Capped Composite

• Best for: Clean, modern finish with minimal upkeep.
• Installed cost: £33 to £59 per m².

The outer cap resists stains and fading. Hose it down and it’s back to looking new.

Pros

• ✔ Excellent stain and fade resistance.
• ✔ Light, consistent decking boards.
• ✔ Very easy to wash down.

Cons

• ✖ Less natural texture.
• ✖ Can feel warm in strong sun.
• ✖ Trims and clips add to cost.

IPE

• Best for: High-end, long-lasting finish.
• Installed cost: £118 to £173 per m².

IPE is a dense tropical hardwood and one of the most premium decking materials available. It's extremely durable, naturally resistant to rot and insects, and can last 25 years or more with minimal care. The trade-off is cost — it's the most expensive option, at £118 to £173 per m² installed. Best suited to homeowners who want a high-end finish and are happy to invest accordingly.

Pros

• ✔ Exceptionally durable and long-lasting.
• ✔ Naturally resistant to rot, insects, and moisture.
• ✔ Very low maintenance compared to other timber options.

Cons

• ✖ Most expensive decking material on the page.
• ✖ Heavier and harder to cut than softwood.
• ✖ Must be sustainably sourced — always check certification.

Garden Decking Planning Permission and Building Regulations

Planning Permission

In most cases, garden decking is permitted development and doesn't require planning permission. However, you will typically need permission if your decking:

• Is more than 30cm above ground level.
• Sits in front of the main elevation of the house.
• Covers more than 50% of the garden, including any existing extensions or outbuildings.

Always double-check with your local authority before starting, especially if you're in a conservation area or have a listed building. If work goes ahead without the right consent, councils can issue enforcement notices.

Building Regulations

Most low-level decking doesn't require formal building regulations approval, but there are a few rules worth knowing. Keep the finished deck at least 150mm (about one brick course) below the damp-proof course, and leave a clear gap at the wall so water can drain away freely.

Raised decking that requires guarding will need balustrades at least 900mm high, with spindle gaps of no more than 100mm. If in doubt, your installer should be familiar with the relevant requirements — it's worth asking them to confirm compliance as part of the quote.

What Does a Garden Decking Installation Involve?

Installing garden decking can be straightforward on flat ground, but sloped gardens, raised decks, or more complex designs are best left to a professional. Getting at least 3 quotes before committing is always a good idea — use MyJobQuote to get free, no-obligation quotes from decking installers near you.

Before the Job Starts

• Plan and prep: Your installer will mark out the space, check drainage falls away from the house, and clear any turf or slabs. A weed membrane will be laid for low-level decks.
• Agree the spec: Confirm the board type — timber, composite, or PVC — and the support method, such as pads, ground screws, or pedestals. Make sure joists, fixings, rails, steps, and any lighting are all agreed and included in the quote before work starts.

During the Job

• Subframe first: Pads or footings are set, then a level frame is built with the correct joist centres. Noggins are added and timber is kept lifted off the soil to allow airflow and prevent moisture damage.
• Boards and edges: Decking boards are laid with consistent gaps — clips are used for composite boards. Fascia, steps, and rails are fitted where needed to finish the edges cleanly.

After the Job

• Tidy up: Offcuts and waste are removed on completion. If skip hire isn't included in the quote, agree in advance who is responsible for waste disposal.
• Protect and check: Once timber decking has dried, it's oiled or stained. Rails and steps are tested for stability, and drainage away from the house is confirmed before sign-off.

Can I Install Decking Myself?

It's possible to install decking yourself, but it's not recommended unless you have solid carpentry experience and a good understanding of local building regulations. Mistakes with levels, drainage, or the subframe can lead to safety issues and costly repairs further down the line.

However, if you’re determined to DIY your decking, here are some tips to consider:

• Start small: Build confidence with a simple, ground-level deck before tackling anything more complex or raised.
• Check building regulations: Make sure your project complies with local rules around height, drainage, and balustrade requirements to avoid fines or having to redo work.
• Choose a material that suits your skill level: Pressure-treated softwood is the easiest option for most DIYers. A composite or PVC decking project needs specific clips, spacing tools, and saw blades.
• Use the right tools: Accurate installation depends on having the right equipment. Hiring tools is a cost-effective option if you don't want to buy outright.
• Get an extra pair of hands: Having someone with carpentry experience helping out makes the job safer and quicker, especially when setting the subframe.

DIY decking can reduce costs significantly, but only if the job is done correctly. If you're unsure about any part of the project — particularly the subframe, drainage, or planning requirements — getting a professional quote first gives you a useful benchmark and may change your mind either way.

Checklist: Hiring a Garden Decking Installer in the UK

Before hiring a decking installer, run through these points to make sure you're getting a fair price and a professional finish.

• Can you show me 2 to 3 like-for-like written quotes? Make sure scope, materials, waste removal, VAT, and start date are all clearly listed.
• Do they have public liability insurance? Ask who is responsible if buried pipes or cables are damaged during the job.
• Can I see recent work? Ask for before and after photos and at least 2 references from past customers.
• Have we agreed on the build details? Confirm board type, joist centres, fixings, rails, steps, and ventilation under the deck before work starts.
• How will you treat cut ends and exposed timber? Ask what preservative is used on cut ends — this is often overlooked and affects the lifespan of the deck.
• Is waste removal included? Confirm whether old turf, soil, and offcuts are being removed as part of the job or charged separately.
• What's the payment plan? A small deposit followed by staged payments is standard. Never pay the full amount upfront.
• How long will it take and what are the access arrangements? Agree the timescale, working hours, parking arrangements, and what happens in the event of weather delays.
• What warranty and aftercare do you offer? Ask for a workmanship guarantee, details of any product warranties, and a clear process for dealing with any issues after completion.
