A patio is a paved outdoor area next to the house or in the garden, laid in porcelain, natural stone or concrete slabs on a compacted sub-base and mortar bed, with falls that direct rainwater away from the house.
Every house in Chelsea is a little different, so we never price a new patio from a brochure. We look at the structure, access and existing finishes first, then put in writing a fixed figure for the scope we settle on. As a rough steer, homeowners in London should budget £3,200–£7,200 including VAT, with work typically taking 3–7 days on site.

What should you budget for a new patio in Chelsea?
In Chelsea, guide figures for a new patio sit at £3,200–£7,200, VAT included. We set them using rates for London, currently about 30% above the national guide. The table shows what pushes a project towards either end of the range; your own price is set after a free survey.
| Type of job | What it usually involves | Guide in Chelsea |
|---|---|---|
| Small patio or path | Around 10m² of concrete slabs or a garden path. | £1,300–£3,200 |
| Typical 20m² patio | Sandstone or porcelain on a full sub-base with jointing and edging. | £3,200–£7,200 |
| Large or multi-level patio | Bigger areas, steps, retaining walls or premium stone. | £7,200–£15,500 |
The main things that change the figure:
- Patio area and the amount of excavation
- Slab material, size and laying pattern
- Ground levels, slopes, steps and retaining walls
- Drainage needed to keep water away from the house
Scope of the work
- Survey of levels, damp-proof course, drainage and access
- Compacted MOT Type 1 sub-base
- Slabs laid on a full mortar bed with falls away from the house
- Jointing with mortar or a brush-in compound
- Edging and neat cuts around drains and walls
- Site cleared, waste removed and paving cleaned
Local housing and a new patio
London's housing is dominated by Victorian and Edwardian terraces, often in yellow London stock brick, with Georgian terraces in central districts and mansion blocks across many inner areas. Outer boroughs have large belts of interwar semis, and there are extensive post-war council estates. Many houses have been split into flats, and conservation areas are widespread.
London Clay shrinks and swells with the seasons, and street trees close to houses can contribute to movement, which affects foundation design.
So when we survey a Chelsea property for a new patio, the first step is working out how it was built and what has been changed since.
Permissions for a new patio in Chelsea
As Chelsea is in England, read the following with that system of planning and building control in mind. We check what applies to your house with the council before you receive a quote.
A ground-level patio in a back garden does not usually need planning permission in England. Raised decks or platforms more than 30 cm high do.
Building Regulations do not normally apply to patios, but levels must stay below the damp-proof course and drain away from the house.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
How does the job run?
Free site survey
We begin by looking at the job in person. During the free survey we discuss options, materials and budget for a new patio, and photograph or measure anything the quote needs to reflect.
Your fixed price
The quote arrives in writing, not over the phone. It covers the full scope, the finishes you've chosen, any exclusions and the payment schedule, with a fixed price tied to that specification.
Booking the work
Preparation matters as much as the build. We agree access, parking and working hours with you, order materials in good time, and confirm any permissions so the job isn't held up once it starts.
Build and hand over
The work is carried out to the agreed specification, with floors and furniture protected and the site kept tidy. At the end we clean up, walk through the finished job with you and hand over any certificates.

Questions about a new patio in Chelsea
How much does a new patio cost?
A typical 20m² patio in sandstone or porcelain costs £3,200–£7,200, including excavation, sub-base, laying and jointing. As a guide, allow roughly £100–£220 per square metre plus fixed costs for set-up and waste. Concrete slabs cost less, while slate, granite and large-format porcelain cost more. Steps, walls and drainage add to the total. We confirm a fixed price after the survey.
Can I stay at home during the work?
In most cases, yes. Most people can live at home throughout, and we plan the work to keep disruption down by protecting floors, agreeing working hours and keeping access routes clear. Bigger jobs affecting kitchens, bathrooms or heating may mean a short spell with reduced facilities, and we talk this through with you at the survey.
How long does it take to lay a patio?
Laying a typical 20m² patio takes around three to five days, from excavation and sub-base to laying, jointing and cleaning. Larger or multi-level patios with steps and walls take longer. The mortar bed needs time to set, so light foot traffic is usually fine after a day or two and furniture can go on after about a week. We confirm timings with your quote.
How much will a new patio cost in Chelsea?
As a guide, expect to pay £3,200–£7,200 including VAT for a new patio in Chelsea. That range is adjusted for London, which runs about 30% above the national guide. Where your project lands depends on size, materials, access and the condition of what is already there. We confirm a fixed price in writing after a free survey of your home.
What should I do before the work starts?
Before work starts, clear garden furniture, pots and ornaments from the area and agree where materials will be delivered and stored. We need a route for wheelbarrows and, on larger jobs, a small digger, so let us know about side gates, narrow passages or access through the house. Tell us about any known drains, cables or pipes in the area.
