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.

Homes in London
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.
That variety is why a guide price for a new patio in Northolt is only a starting point; the survey shows what your particular property needs.
Planning and building rules in Northolt
For anyone in Northolt, the relevant framework is England's. The summary below is general, so we always contact the council about your address before putting a price in writing.
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.
From survey to handover
We look at the job
We arrange a free site survey on a date convenient to you. We measure up, look at the existing structure and access, and discuss your plans for a new patio so the price reflects your home.
Your fixed price
After the survey we send a quote for a new patio that fixes the price for the scope we've agreed. If you want to change materials or scope, we revise it in writing before anything is booked.
Getting ready
We handle the paperwork side: checking whether planning permission or building control approval is needed, submitting applications where they are, and scheduling the trades and materials around your dates.
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.

Frequently asked questions
How much will a new patio cost in Northolt?
As a guide, expect to pay £3,200–£7,200 including VAT for a new patio in Northolt. 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 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 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.
Does a patio need planning permission?
Most patios do not need planning permission, but it depends on the size, height and location, your home's position, whether it is listed or in a conservation area, and which UK nation you are in. Raised patios or decking more than a small height above the ground may need permission because of overlooking. We check the position for your garden before quoting.
