What is included?

Tarmac resurfacing, or an overlay, means cleaning and repairing an existing drive, spraying a bond coat and laying a new surface course of about 25–40 mm on top, without digging out the base.

Survey of the existing base: sinking, rutting, loose edges and drainage
Cut out and patch failed areas before overlaying
Plane or cut back at thresholds, kerbs and covers so levels still work
Weed treatment and a clean surface
Bond (tack) coat sprayed to glue the new layer to the old
Edges sealed and joints to existing surfaces cut neatly

Rules in Hertfordshire

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. Any new or widened crossing over the pavement needs approval from the highway authority (the county or unitary council).
