What to know before a driveway extension in Hertford
Homes in Hertford include plenty of semis and detached houses with room for a drive, plus older terraces where parking is tighter.
Flat ground across much of the East means falls have to be built in carefully so water does not sit on the drive.

What you get with our drive extensions service
A driveway extension adds paving to an existing drive, usually to fit a second car by taking in part of the front lawn, or to lengthen a drive towards the house or garage. The new section is built on its own sub-base and tied into the old paving so the two act as one surface.
- Check of the existing drive: block range, thickness, levels and condition
- Dig-out and sub-base for the new area
- Joint sand, compaction and a clean-down of the old section
- New edging, kerbs or a low retaining edge where the lawn is cut back
- Matching options: same range, re-mixing old and new, or a planned contrast
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
- Edges against lawns, beds, walls and neighbours
- Block range, thickness, colour and pattern to suit the house
- The kerb: is it already dropped, and is it wide enough?
Planning and kerb rules in Hertford
Hertford 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.
