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.
Addresses across SW1, SW1A, SW1E and SW1H fall within our coverage for a new patio, so if your home is in Westminster we can arrange a survey on a day that works for you. We inspect the existing building, discuss materials and layout, and then price the agreed specification in writing. Expect a guide range of £3,200–£7,200 including VAT before that visit.

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.
Terraces suit side-return extensions and rear dormer loft conversions; interwar semis commonly take hip-to-gable lofts. Shared party walls, restricted parking and conservation rules often shape the plans and the programme.
Knowing the typical building types in London helps, but a survey of your own home in Westminster is what decides the right approach to a new patio.
Permissions for a new patio in Westminster
Because Westminster falls under England's rules, the guidance below is the version relevant to you. Before sending a price, we check your property's position with the council.
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.
The four stages
Survey and measure
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.
Written quote
We put everything into a written, fixed-price quote: the specification, what's excluded, staged payments and the expected time on site. Take whatever time you need to decide; there's no pressure to commit.
Getting ready
Once you accept, we agree start dates, order materials and deal with any planning, building control or neighbour notices the job needs. You'll know who is coming and when before work begins.
On site to finish
Our trades complete a new patio while your point of contact keeps you updated. When everything is finished, we clear the site, take away waste and go through the result with you before handover.

Common questions
What happens at the survey?
We visit your home at a time that suits you, look at the area involved, take measurements and check access, condition and any services that might be affected. We talk through what you want from a new patio, explain the options and answer questions. There is no charge and no obligation; afterwards we send a written quote.
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.
How much will a new patio cost in Westminster?
As a guide, expect to pay £3,200–£7,200 including VAT for a new patio in Westminster. 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 happens if my garden slopes?
A sloping garden can still have a level patio by cutting into the slope, building up with retaining walls, or creating terraces with steps between them. Retaining walls must be built to hold back the soil and allow drainage behind them. This adds cost but creates usable, level space. We look at the slope during the survey and suggest the most practical design.
How do I clean and look after my patio?
Most patios just need regular sweeping and an occasional wash with water and a mild patio cleaner. Porcelain is the easiest to keep clean. Natural stone benefits from a sealant to reduce staining and from prompt cleaning of spills like oil or wine. Re-point any joints that crack or wash out. Avoid high-pressure jet washing close to joints, which can damage them.
