What to know before a replacement block drive in Mountain Ash
Around Mountain Ash, plots are often larger and drives longer, so edging, falls and the route the water takes need planning.
Wales is wetter than most of England, and new front paving has to be permeable or drain within the property, so drainage is designed in from the start.
How much does a replacement block drive cost in Mountain Ash?
In Wales, a replacement block drive usually costs £90–£165 per m² including VAT. For a 45 m² replacement drive, that is roughly £4,000–£7,550. Your exact price depends on what the survey or your photos show, and is fixed in writing before anything is booked.

What does a replacement block drive involve?
Sometimes the old base can be kept: a thick, sound concrete or well-compacted hardcore layer may only need trimming and topping up. Often it cannot, because it was too thin, has sunk or sits too high against the house. The survey checks levels against the damp-proof course and the existing base before the quote is written, so the price reflects the real dig.
- Drainage added where the old drive sent water to the house or road
- Break-out of the old surface with waste removal and skip or grab lorry
- New edging, sub-base where needed, and the block drive
- Levels set below the damp-proof course with falls away from the house
- Assessment of the old base: keep, top up or replace
Before we price your replacement block drive
- Where an electric vehicle charger cable might run
- Levels against the damp-proof course (the finished paving must sit at least 150 mm below it)
- Trees and roots near the drive
- Whether front-garden planning rules apply
- Access for a mini-digger, skip or grab lorry
Rules for front drives in Mountain Ash
Mountain Ash is in Wales, so these rules apply:
In Wales, any new or replacement hard surface at the front of a house should be permeable or drain to a permeable area within the property to avoid needing planning permission. Unlike England, there is no 5 m² allowance for new paving; only repairs of up to 5 m² of existing surface are exempt.
Since January 2019, construction work covering 100 m² or more with drainage implications, including drives and patios, needs approval from the local SuDS Approving Body (SAB) before work starts, even where planning permission is not needed.
A dropped kerb needs your council's approval as highway authority, and a new access onto a classified road needs planning permission.
General guidance, not legal advice. Your survey confirms what applies to your home. See the planning guide.
