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.
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.
Best time of year for driveway installation
Tarmac and resin installation generally prefer drier, milder conditions for proper curing — many installers have a quieter season in deep winter, which can sometimes mean better availability and slightly better pricing, though weather delays are more likely too.
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.
What a good driveway quote should include
A proper quote should specify material and base depth/preparation (not just "block paving" or "tarmac"), whether excavation and disposal of the old surface is included, drainage provision, and edging details. Base preparation quality affects the driveway's lifespan more than most people expect.
How driveway quotes work
Describe the current driveway (if any), desired material, and rough size — an initial estimate can follow, but a firm quote needs a site visit to assess ground condition, drainage, and access, since these significantly affect groundwork cost beyond the visible surface material.
Aftercare for different driveway materials
Tarmac needs light use for the first few days after laying. Resin bound surfaces should be kept clear of standing water pooling in the first weeks. Block paving benefits from periodic re-sanding of joints and occasional weed treatment. Ask your installer for material-specific aftercare guidance.
Tree roots and driveway heave
Established tree roots near a driveway can cause the surface to lift or crack over years, particularly with certain species known for aggressive root systems — worth discussing nearby trees with your installer, since root barriers or a different material choice can sometimes mitigate this.
