What to know before a block paved patio in Carshalton
Homes in Carshalton include plenty of semis and detached houses with gardens big enough for a patio and a path to the gate.
A patio or path needs the same care underneath as a drive: a compacted base, edges set in concrete and falls that take water away from the house.
How much does a block paved patio cost in Carshalton?
For Carshalton, our guide is £95–£170 per m² including VAT, so a 20 m² patio is likely to be £2,200–£3,850. Smaller jobs cost more per square metre because set-up and waste costs do not shrink with the area.

What you get with our patios service
Block suits patios that join a block drive or path, small or awkward spaces where large slabs would need too many cuts, and gardens where you want a pattern such as basketweave or a circle feature. We lay patios to fall away from the house and below the damp-proof course, with edging that stops the blocks creeping into the lawn.
- Blocks in your pattern, edges and cuts
- Dig-out and compacted sub-base (around 100 mm for foot traffic)
- Jointing sand and compaction
- Layout marked out with you, including steps and doors
- Optional sealer
Before we price your block paved patio
- Manhole and inspection covers in the area
- Ground conditions and how deep the dig must be
- Levels against the damp-proof course and door thresholds
- Block range, colour, pattern and border to suit the house
- Steps, walls and changes of level
Do you need permission for a block paved patio in Carshalton?
A patio or path behind the house does not usually need planning permission. Raised patios, listed buildings and flats can be different, so we check on the survey.
Paving in front of the house follows the front-garden rules: in England, a front drive over 5 m² needs planning permission unless it is permeable or drains to a lawn or border within your boundary.
