Driveway drainage regulations
Since 2008, planning permission is needed for a new or replacement driveway over 5 square metres using non-permeable material unless the water is directed to a permeable area (like a lawn) rather than the road. Permeable options (block paving with permeable jointing, gravel, resin bound) avoid this requirement — worth checking with your installer before committing to material.
Tarmac driveways, what to expect
Tarmac is quick to lay and cost-effective for larger areas, cures over a period after laying (avoid heavy use for the first few days), and can be edged with block paving for a more finished look. It's less visually varied than paving but a practical, durable choice for straightforward driveway replacement.
Permeable paving explained
Permeable block paving uses jointing material that lets water drain through into the ground below rather than running off, which avoids the planning permission requirement that applies to non-permeable driveways over 5 square metres. It generally costs a bit more than standard block paving but avoids a planning application.
How long does driveway installation take?
A small driveway resurfacing is often 1-2 days. A full new driveway including excavation, base preparation and surfacing commonly takes 3-7 days depending on size and material — resin and block paving generally take longer than tarmac for the same area.
Weed prevention in driveways
Proper base preparation (a weed-suppressing membrane, adequate sub-base depth) prevents most weed growth from underneath. Weeds establishing in joints between blocks over time is normal and manageable with occasional treatment or re-sanding, not usually a sign of installation failure.
What affects the cost
Cost depends on material, driveway size, ground condition (excavation and disposal if the existing surface needs removing), drainage requirements, and access for machinery and material delivery. A driveway on a slope or with poor existing drainage costs more due to the groundwork involved, not just the surface material.
Common driveway and paving jobs
Driveway specialists cover new driveway installation (block paving, tarmac, resin, gravel), resurfacing an existing driveway, paths, and kerb dropping to create vehicle access from a road. Repairs to cracked or sunken sections are usually a smaller, separate job from a full installation.
Driveway regulations, FAQ
Do I need planning permission for a new driveway? Only if it's over 5 square metres and uses non-permeable material without proper drainage to a permeable area. Do I need permission for a dropped kerb? Yes, separately, from your local council's highways department, regardless of the driveway material.
