Planning a replacement block drive in Harrow
Harrow has everything from short terrace frontages to wide drives on newer estates, so the survey sets the layout and the dig.
Front gardens in much of London are short, so parking depth and the dropped kerb usually decide whether a drive is possible.
How much does a replacement block drive cost in Harrow?
For Harrow, our guide is £115–£215 per m² including VAT, so a 45 m² replacement drive is likely to be £5,150–£9,700. Smaller jobs cost more per square metre because set-up and waste costs do not shrink with the area.

What you get with our replace an old drive service
Replacing an old drive with block paving means breaking out the existing tarmac, concrete or gravel, checking what is underneath, and then building a block drive on a sound base. Many older tarmac and concrete drives have cracked, sunk or broken up, which is why this is such a common way into block paving.
- New edging, sub-base where needed, and the block drive
- Drainage added where the old drive sent water to the house or road
- Assessment of the old base: keep, top up or replace
- Levels set below the damp-proof course with falls away from the house
- Break-out of the old surface with waste removal and skip or grab lorry
What the survey covers
- Ground conditions under the old surface and how deep the sub-base must be
- Where an electric vehicle charger cable might run
- Whether front-garden planning rules apply
- Block range, thickness, colour and pattern to suit the house
- The kerb: is it already dropped, and is it wide enough?
Rules for front drives in Harrow
Harrow is in England, so these rules apply:
In England, paving in front of the house that covers more than 5 m² needs planning permission unless it is permeable or drains to a lawn, border or soakaway inside your boundary. Permeable block paving, or standard blocks laid to fall onto a planted strip, avoid the need for permission in most cases.
Flats and maisonettes, listed buildings, and homes covered by an Article 4 direction can have tighter rules, and conservation areas, National Parks and National Landscapes restrict some permitted development.
A dropped kerb needs your local highway authority's approval (usually the county, unitary, metropolitan or London borough council), and a new access onto an A, B or C classified road also needs planning permission.
General guidance, not legal advice. Your survey confirms what applies to your home. See the planning guide.
