Patio Installers London
KiKK Groundworks builds patios across North, South, East, West and South West London. Small gardens, no side access, London Clay underneath and a damp proof course to respect. That is the real job. The slabs are the easy part.

Most London gardens are small, enclosed, overlooked on three sides, and reachable only through the house. There is no gate, no side return wide enough for a mini digger, and nowhere to stack a pallet of slabs. That single fact controls the price, the programme and the choice of contractor more than the material ever will.
On a terraced job in London, four tonnes of aggregate come in one barrow at a time through your hallway, across boarded and sheeted floors, and six tonnes of spoil go back out the same way in bulk bags. Where the layout allows, we use a conveyor over the wall or a neighbouring side passage instead. Either way it is hours of labour that a Norfolk job simply does not have, and it is why a London patio costs what it costs.
We survey that route before we price the work. Company websites that quote a flat rate per square metre for London have not looked at your garden. When a contractor discovers the access problem in week two, the conversation is about extras. We would rather have it on day one, in writing, in the quote.
And then there is the ground. Most of London sits on London Clay, which shrinks and swells with the seasons. A patio bedded straight onto that clay with 50mm of sand under it will heave in winter and drop in summer. Slabs rock. Joints crack open. The fall reverses, and water that was supposed to run away from the house starts sitting against the wall instead. The surface is never the problem. The prep is.
London Clay moves seasonally. We excavate and compact MOT Type 1 to the depth the ground actually needs, not the depth that keeps the quote low.
Every patio falls away from the building, clears the damp proof course by 150mm, and discharges somewhere legal. Not onto a neighbour.
Kallan is on site personally. No subcontracted labour turning up on day one having never seen the garden.
Street works accredited and fully insured. Skip permits, bay suspensions and ULEZ-compliant plant handled as part of the job.
Access, muck-away and permits priced as visible line items. You see what the difficult parts of a London job actually cost.
A patio is a groundworks job with a nice surface on top. We come at it from the groundworks side, which is the side that fails.
What suits a Victorian terrace in Islington is not what suits a 1930s semi in Ealing or a new-build courtyard in Stratford. Material choice in London is part aesthetics, part conservation area, and part how much of it you can physically carry through the house.
Porcelain has become the dominant patio surface in London, and it earns it. It is dimensionally stable, so joints stay tight. It does not need sealing. It does not stain from grease or wine. It holds its colour, and in a city with genuine airborne pollution it stays looking clean with a brush and a hose.
There is one rule with porcelain and it is not negotiable. It must be laid on a full mortar bed, with a primer slurry brushed onto the back of every single slab. Porcelain is non-porous, so nothing keys into it without that slurry. A spot-bedded porcelain patio, with five dabs of mortar under each slab and a void in between, will crack, ring hollow, and lift within two winters. Most cheap London quotes are spot-bedded. Ask.
Guide cost installed: £160 to £260 per m², depending on access and slab.
Against London stock brick, in a conservation area, next to a period rear extension, yorkstone is often simply the right answer. Riven or sawn, new or reclaimed, it weathers into the building instead of arguing with it. Some boroughs will expect it, and if your property is listed the material choice may not be entirely yours.
Indian sandstone remains the workhorse of the London garden at the sensible end of the budget. Limestone gives a softer, more uniform look but needs sealing and will mark. All natural stone is porous, so it wants a full mortar bed and correctly specified jointing compound, and it will want cleaning down every couple of years.
Granite setts are the toughest thing you can put in a London garden and the most sympathetic to a period property. They also break up a small space beautifully as a border, a threshold, or a band between a patio and a lawn. Block paving is the value option and lends itself to permeable jointing, which matters more in London than most homeowners realise.
We also build the parts of the patio that are not the patio: retaining walls, steps, thresholds, raised beds, edge restraints and channel drainage. On a sloping or terraced London garden that is often half the work.
London gardens are rarely flat and rarely level with the house. A raised ground floor with the garden a metre below, a stepped terrace, a lower-ground flat with a lightwell, or a slope running away towards the rear wall. Resolving that means retaining walls, steps and a proper structural approach to levels before a single slab is cut.
The rule that gets broken most often in London is the damp proof course. The finished patio surface must sit at least 150mm below the DPC, and it must fall away from the building at roughly 1 in 80. Pave up over the DPC and you have built a bridge for water into your brickwork. The damp appears inside six months later and gets blamed on everything except the patio. Where the levels genuinely will not allow 150mm, the answer is a linear channel drain running along the house, tied into a soakaway, not a patio shoved up against the render.
Water also has to go somewhere legal. In tightly packed London gardens you cannot simply fall the patio towards next door and let it discharge onto their land, which is precisely what a surprising number of installations do. We design the falls, the channel drainage and the soakaway as one system, and we tell you where the water ends up.
Then there is run-off. A large impermeable patio in a city whose combined sewers are already at capacity is a real contribution to surface water flooding, and The London Plan pushes hard on sustainable drainage. Permeable jointing, permeable block paving, and a properly sized soakaway keep the water on your plot rather than in the sewer. Where drainage is the whole problem rather than part of it, see our London drainage service.
London prices are higher than the national averages you will find quoted online, and that is not a mark-up. Labour costs more, muck-away costs more, skip permits and CPZ bay suspensions come from the borough, plant and lorries have to be ULEZ compliant, and hand-balling everything through a house adds days. Figures below assume a 25m² patio including excavation, spoil removal, compacted MOT Type 1 sub-base, full mortar bed and jointing.
| Material | Cost Per m² | Avg 25m² Patio | Lifespan | Maintenance |
|---|---|---|---|---|
| Porcelain Paving | £160 - £260 | £4,000 - £6,500 | 30+ years | Very Low |
| Natural Stone (Sandstone) | £140 - £230 | £3,500 - £5,750 | 25-40 years | Low-Medium |
| Yorkstone | £190 - £300 | £4,750 - £7,500 | 50+ years | Low-Medium |
| Granite Setts | £180 - £300 | £4,500 - £7,500 | 50+ years | Low |
| Limestone | £150 - £240 | £3,750 - £6,000 | 25-40 years | Medium |
| Block Paving | £110 - £170 | £2,750 - £4,250 | 30-40+ years | Low-Medium |
Add roughly 15 to 30 per cent where there is no rear access and all materials and spoil move through the house. Retaining walls, steps, soakaways and a new channel drain are priced separately. Combining a patio with a new London driveway in one contract usually works out cheaper than two visits, because the permits, plant and muck-away are shared.
These are guide prices only, pending a site visit. Every London garden is different and access changes the number. We provide a written fixed-price quote after we have walked the site.
We will walk the access route, check the levels against your DPC, and put the difficult parts in writing.
We walk the route materials will take, check levels against the DPC, and price the access honestly before anything is agreed.
Skip permit or grab lorry booked with the borough, bays suspended, floors boarded and sheeted if we are coming through the house.
Excavate to formation, remove spoil, compact MOT Type 1 in layers, set the falls, and install channel drainage or a soakaway where needed.
Full mortar bed, primer slurry on every porcelain slab, joints pointed, garden cleared and left clean. Nothing left in the side return.
London does not behave like one place, and neither do its gardens. The ground, the housing stock and the access problem all change depending on where you are.
Wandsworth, Clapham, Balham, Putney, Battersea, Richmond, Wimbledon and Fulham. Long, narrow Victorian gardens behind terraces with no side access at all, sitting on some of the most active London Clay in the city. Mature street trees make seasonal movement worse. This is where the full mortar bed, the proper sub-base depth and an honest access price matter most, and it is where most of our combined patios and driveways in South West London work sits.
Islington, Camden, Highgate, Crouch End, Muswell Hill, Barnet and Finchley. Steep, terraced gardens with real level changes, lots of conservation area coverage, and period properties where yorkstone and granite setts read better than porcelain. Retaining walls and steps are part of the job here far more often than not.
Dulwich, Herne Hill, Brixton, Greenwich, Blackheath, Bromley and Croydon. A mix of Victorian terraces and larger 1930s plots. More gardens here have rear or side access, which brings the cost down noticeably, and larger plots mean soakaways and permeable jointing are genuinely straightforward to design in.
Hackney, Bow, Walthamstow, Leyton, Stratford and the Docklands. Small courtyard gardens, new-build terraces and converted warehouse spaces where the entire garden is the patio. Tight controlled parking, restricted working hours, and skips that need a borough permit before they touch the road.
Ealing, Chiswick, Acton, Hammersmith, Kensington and Chelsea. High-spec finishes, conservation areas and listed buildings, and gravel terrace ground in places rather than clay, which behaves differently underfoot. Materials frequently have to be specified to satisfy the borough as well as the client.
We are a groundworks contractor that lays patios, not a landscaping outfit that subcontracts the digging. On London Clay, in a garden you can only reach through a hallway, that distinction is the whole job.
Patios are one of seven services we run across the capital. See the full London groundworks hub, or read about foundations and underpinning in London if movement in the ground is already showing up in the building.
FAQ
London patio costs are driven as much by access as by material. A typical 25m² porcelain patio with a full mortar bed runs £4,000 to £6,500 installed. Natural stone and yorkstone run £3,500 to £6,000. Granite setts run £4,500 to £7,500. Where there is no rear access and everything comes through the house by barrow, add roughly 15 to 30 per cent to the labour and muck-away. Skip permits, CPZ bay suspensions and ULEZ-compliant plant are separate line items and we show them in the quote rather than hiding them in the rate. All figures are guide prices pending a site visit.
A patio in a rear garden laid at ground level is normally permitted development and needs no planning permission. Three London exceptions matter. If the property is listed, listed building consent may be needed. If it sits in a conservation area, the borough may have an Article 4 direction affecting materials or front gardens. And if you are paving a front garden with an impermeable surface over 5m² that drains to the highway, planning permission is required. Raised terraces and decking above 300mm can also need permission. We confirm which rules apply to your address before quoting.
By hand, and we plan for it. Slabs, aggregate and mortar are barrowed through the house on boarded and sheeted floor protection, or lifted over via a neighbouring property or a conveyor where the layout allows. Spoil comes out the same way into bulk bags, then to a grab lorry or skip on a permitted bay. On a terraced London job the muck-away and material handling is often the single biggest line in the quote, and we tell you that at the site visit instead of discovering it in week two.
Porcelain is the default in most of London now. It is dimensionally stable, needs no sealing, does not stain from barbecue grease, holds its colour and stays clean in a city with real airborne pollution. Natural stone and yorkstone suit period properties and conservation areas, where a rectified porcelain slab can look wrong against Victorian brick and where the borough may expect a traditional material. Porcelain must be laid on a full mortar bed with a slurry primer on the back of every slab. Spot-bedded porcelain fails.
Yes, if it is laid wrong. The finished patio surface must sit at least 150mm below the damp proof course, and it must fall away from the building at roughly 1 in 80. A patio that bridges the DPC, or that falls back towards the wall, will push water into the brickwork and produce damp inside. This is one of the most common defects we are called to correct in London. Where levels do not allow 150mm of clearance, the answer is a linear channel drain against the house tied into a soakaway, not a patio pushed up against the render.
A straightforward 20 to 30m² patio with reasonable access takes four to seven working days. A terraced London garden with no side access, spoil coming out through the hallway, and a metre of level change to resolve with retaining walls and steps will run seven to fourteen days. Porcelain on a full mortar bed needs curing time before it is jointed and loaded. We give a written programme with the quote, and we work to the borough's permitted hours.
