Every summer, the same debate runs through British gardens: decking or patio? Both transform an outdoor space, both add genuine kerb appeal, and both come with their own set of costs, quirks, and caveats. But with the average UK garden renovation budget getting squeezed tighter each year, the question of which option actually delivers better value matters more than ever in 2026.
This is a proper cost-by-cost look at timber decking versus stone patio installation, covering what you’ll realistically pay, what the planning rules say, how much upkeep you’re signing yourself up for, and crucially, which one holds up when Britain does what Britain does best: rain.
What Does Timber Decking Actually Cost in 2026?
Timber decking remains a popular choice, particularly for gardens with uneven ground or sloping plots where laying a level patio would require significant groundwork. For a basic pressure-treated softwood deck covering around 20 square metres, you’re typically looking at £1,500 to £3,000 fitted, including labour. Move up to composite decking (the engineered wood-alternative boards that have taken over in the last five years), and that same 20 square metres jumps to roughly £3,000 to £6,000.
Hardwood decking sits somewhere in between in terms of longevity but closer to the composite end on price. A skilled local carpenter fitting Ipe or Bangkirai hardwood boards will often quote £4,000 to £7,000 for a mid-size project. Don’t forget to factor in hidden costs: joists, frame materials, concrete footings if needed, and the fixings themselves. These can add 15 to 20 per cent on top of the board quote.
Stone Patio Installation: What Are the Real Costs?
A stone patio, when laid properly on a solid sub-base with correctly mixed mortar, can genuinely last decades. The price range is broad because the material choice varies so wildly. Here’s a rough breakdown per square metre installed:
- Indian sandstone: £70 to £120 per m²
- Porcelain tiles: £90 to £160 per m²
- Natural limestone: £100 to £180 per m²
- Concrete pavers (budget option): £40 to £80 per m²
For that same 20 square metre space, Indian sandstone would typically land between £1,400 and £2,400 fully installed. Porcelain, which has become enormously fashionable and is arguably the most durable of the lot, pushes up to £1,800 to £3,200. That sub-base matters enormously too: a reputable landscaper will insist on at least 100mm of compacted MOT Type 1 hardcore beneath the mortar bed. Cut corners here and you’ll be re-laying slabs within five years.
Do You Need Planning Permission for Decking or a Patio in England?
This catches a surprising number of homeowners out. In England, permitted development rights generally allow you to build a patio at ground level without planning permission, provided it doesn’t raise the ground significantly above the original garden level. Patios are typically fine.
Decking is slightly more complicated. Under permitted development rules, raised decking (anything more than 300mm above ground level) may require planning permission, particularly in conservation areas, Areas of Outstanding Natural Beauty, or if the deck would cover more than 50 per cent of the garden. Properties that are listed buildings have additional restrictions. Always check with your local planning authority before starting work. The Planning Portal has a straightforward interactive guide to help homeowners in England understand what falls within permitted development.
For Wales, Scotland, and Northern Ireland, the rules differ slightly, so it’s worth double-checking with the relevant devolved authority.
Maintenance: Which One Is More Work?
Softwood decking is honest about what it demands. Without annual cleaning and re-oiling or re-staining, it fades, greys, and eventually rots. Pressure-treated boards extend the life considerably, but you’re still looking at treating the surface every one to two years. Budget roughly £150 to £300 a year for products and your own time, or more if you hire someone. Composite decking is far lower maintenance but not zero: it still needs a good scrub down to prevent algae and moss build-up.
Stone patios, once properly laid, need relatively little intervention. An annual jet wash and occasional re-pointing of the joints every five to ten years is usually sufficient. Porcelain in particular is highly resistant to staining and frost. The main enemy of a patio in the UK climate is freeze-thaw damage and the moss that creeps into joints, both of which are manageable with basic upkeep. Over a ten-year period, a well-laid stone patio will almost certainly cost less to maintain than equivalent timber decking.
Which Holds Up Better in Britain’s Wet Climate?
This is the crux of it, really. The UK averages over 1,200mm of rainfall per year in parts of Wales and the north of England. Even the drier south-east sees enough wet months to make material resilience a serious consideration.
Timber, by its nature, absorbs moisture. Even treated softwood will swell, contract, and eventually crack with repeated wet-dry cycles. Composite boards handle this better, though cheaper composites can still discolour and warp after prolonged exposure. Hardwood decking, properly maintained, performs reasonably well but requires genuine commitment.
Stone and porcelain patios, when laid on an adequate sub-base with proper drainage, handle British weather considerably better. Porcelain tiles with a textured surface offer excellent slip resistance, which is a genuine safety consideration during autumn and winter. Indian sandstone can be slippery when wet and may absorb water if not properly sealed, though a quality sealer applied every couple of years largely resolves this.
On pure climate resilience, stone wins. Decking can still be a brilliant choice, particularly for sloping gardens or elevated entertaining spaces, but you’re buying into a material that needs more attention in a wet climate.
Which Adds More Value to a Property?
Estate agents tend to favour patios for long-term value, particularly well-laid natural stone. A quality patio is seen as a permanent improvement that requires little buyer imagination. Decking can divide opinion: some buyers love it, others immediately see it as a future maintenance headache or worry about what’s lurking underneath. Landlords in particular often find that a low-maintenance stone patio is a stronger selling point than timber decking, which tenants may not maintain consistently.
That said, a beautifully designed composite deck with integrated lighting and built-in seating can absolutely increase a property’s appeal. The material is less important than the quality of the finish and the appropriateness for the garden layout.
So Which Should You Choose?
If budget is the primary concern and your garden is relatively flat, Indian sandstone or quality concrete pavers will deliver the most square metres for your money and the lowest long-term costs. If your garden slopes, or you want an elevated outdoor room feel, decking (ideally composite) makes more structural sense and can genuinely transform an otherwise awkward space.
The honest answer is that neither is universally better. It comes down to your plot, your lifestyle, your maintenance appetite, and how long you plan to stay in the property. What’s certain is that cutting corners on either project, using cheap materials or inexperienced labour, costs more in the long run than doing it properly the first time.
Frequently Asked Questions
Is decking or a patio cheaper to install in the UK?
For a basic 20 square metre project, budget timber decking and Indian sandstone patio installations can cost roughly the same, between £1,400 and £3,000 fitted. However, composite decking and premium stone options push costs higher. Over ten years, stone patios tend to be cheaper once maintenance costs are factored in.
Do I need planning permission for decking in my garden in England?
In most cases, ground-level patios don’t require planning permission in England. Raised decking above 300mm may need permission, particularly in conservation areas or if it covers more than half your garden. Always check with your local planning authority or use the Planning Portal before starting work.
How long does timber decking last compared to a stone patio?
Pressure-treated softwood decking typically lasts 10 to 15 years with regular maintenance. Composite decking can last 25 years or more. A well-laid natural stone or porcelain patio can last 30 to 50 years, making stone the more durable long-term option in most circumstances.
Which is safer and less slippery in wet weather, decking or patio?
Both can be slippery when wet. Textured porcelain tiles offer the best slip resistance and are a popular choice for British gardens. Timber decking can become extremely slippery with algae growth and should be cleaned regularly. Anti-slip strips can help, but are an additional cost and maintenance consideration.
What is the best patio or decking material for a UK climate?
Porcelain patio tiles and composite decking boards both perform well in Britain’s wet climate. Porcelain is frost-resistant, low maintenance, and highly durable. Composite decking resists moisture better than timber and won’t rot. Both are worth the higher upfront cost compared to natural timber or cheaper stone alternatives.
