Best patio materials for SW London gardens

A patio is one of the bigger commitments in any garden, and the choice of slab is the bit that gets debated most. The right answer depends on your budget, the look you’re after, and importantly the conditions in this part of London, which are wetter and shadier than most patio brochures assume.

There are three families of patio material we install, and the choice between them is the first conversation we have on any quote. Here’s how we think about each.

Porcelain

The premium option. Porcelain slabs are made of fired clay, so they don’t absorb water and they don’t fade. They’re harder than natural stone, and they almost never stain.

Pros: Almost zero maintenance. No fading, no algae stains, narrow joints that are easy to keep weed-free. The longest lifespan of any patio material we work with, forty years plus on a properly built sub base.

Cons: The most expensive of the three families, roughly 30 to 40 percent more than mid-range natural stone. Trickier to lay (requires a slurry primer on the slab base and very accurate substrate prep, so the labour element is higher). Some ranges look slightly artificial up close.

Best for: Shaded gardens (where natural stone would algae over within a year), modern extensions, anyone whose first priority is “I don’t want to think about this again for fifteen years”.

Per m² fitted: £190 to £260 in 2026.

Natural stone

The middle of the range and where most SW London gardens land. Natural stone covers Indian sandstone, granite, yorkstone and limestone, each with their own look and price point.

The popular pick is Indian sandstone, the warm, riven slab in tones like raj green, modak, mint and kandla grey. It suits the typical Victorian, Edwardian and inter-war housing in this area and it’s the best value of the natural stones.

Granite sits a step up: harder wearing, more uniform in colour, with a slightly more contemporary feel without going as far as porcelain. Silver and dark grey tones suit houses with grey-toned brickwork.

Yorkstone is the heritage option, particularly for cottage or period houses. Heavier on the budget but it ages beautifully.

Limestone is paler and softer in texture than granite, popular on lighter-coloured houses.

Pros: A look you can’t replicate in any other material. Patinas softly with the seasons. Indian sandstone is the best-value patio material once you discount concrete. Long lifespan: twenty-five years plus.

Cons: Porous, so it stains slightly over time. Algae takes hold in shade, especially under trees. Most natural stones need a jet wash and fresh jointing compound every two to three years to stay looking sharp.

Best for: Standard rear gardens that get some sun, where you want a material that’s truly natural and don’t mind a light maintenance routine.

Per m² fitted: £140 to £220 in 2026, depending on the stone (Indian sandstone at the lower end, yorkstone at the top).

Concrete slabs

The budget end of the range and a much better category than it used to be. Modern concrete slabs from Marshalls, Bradstone, Stonemarket and similar are formed and finished to look close to natural stone, and a well-laid concrete patio reads convincingly from a metre away.

Pros: The cheapest patio that still gives you a proper finish. Very consistent in colour batch to batch. Cuts cleanly, which helps on awkward shapes.

Cons: Will fade slightly over years (typically about 15 percent lighter after five years). Some ranges have a colour vibrancy that natural stone doesn’t, which can read as artificial. Lifespan around twenty years before you’d think about replacing.

Best for: Tight budgets, larger areas where the cost difference adds up, courtyard or side-passage surfaces where you don’t need a hero patio.

Per m² fitted: £100 to £150 in 2026.

What about climate?

SW London is wet for at least four months of the year, and most rear gardens have at least one shaded section. Two implications:

• Drainage matters. Whatever the slab, the patio must slope away from the house at 1:80, and there should be somewhere for water to go (a soakaway, or a linear drain at the lowest point).
• Algae is a fact of life on porous slabs. Natural stone and concrete both algae over in shade. A yearly clean prevents it building up. Porcelain doesn’t algae the same way because it doesn’t absorb water.

If your patio site is north-facing or under heavy tree cover, we’ll usually steer you towards porcelain even if it costs more, because a natural-stone patio in deep shade will need cleaning twice a year and will look tired by year three.

What about the house?

The material should suit the house. A general rule:

• Victorian or Edwardian terrace: warm, riven Indian sandstone (raj green, modak)
• 1930s semi: lighter Indian sandstone (mint, kandla grey) or porcelain in a stone-effect range
• Modern extension: porcelain in a clean grey or beige, or granite
• Cottage or country house: yorkstone if budget allows, otherwise Indian sandstone in mellow tones

This is a default, not a rule. Plenty of clients have done the opposite and it’s worked.

A short version

• Best value: natural stone, specifically Indian sandstone
• Best long-term: porcelain
• Best on a budget: concrete slabs (the better ranges)
• Best for shaded gardens: porcelain, no contest
• Best contemporary look without porcelain: granite (a type of natural stone)
