Do I need permission in Harpenden?

In England, householder permitted development (Class F of the 2015 General Permitted Development Order) lets you lay a hard surface in front of a house without planning permission if it is porous, or if the rainwater is directed to a permeable area within the property. If the area is more than 5 m² and neither applies, you need permission. Standard dense tarmac is not porous, so a dense tarmac drive needs a lawn, border, channel to a soakaway or other permeable route for its water. If the job needs a dropped kerb, the highway authority (the county or unitary council) approves it before any work on the footway.

What the price covers

Tar and chip, also called surface dressing, is a layer of bitumen sprayed onto a prepared base and immediately covered with stone chippings, which are rolled in so the surface looks like gravel but behaves like a bound drive.

Base prepared: new MOT Type 1 sub-base, or an existing sound tarmac or stone base
Edges set with kerbs, setts or cobbles
Hot bitumen or emulsion sprayed evenly
Chippings spread straight onto the binder
Loose surplus chippings swept up after a few days
