Should I Repair or Replace My Driveway?

Driveway repairs range from a minor crack fill (£50–£150 DIY) to a full resurfacing (£2,000–£8,000+). The good news is that many driveway problems are surface-level and repairable without ripping everything up. Whether you choose to repair or replace depends heavily on the material, the extent of damage, and how old the driveway is.

Full block paving (new, avg size)	£3,500 – £8,000

How Long Should a Driveway Last?

Tarmac driveways last 20–30 years with occasional resurfacing. Block paving lasts 20–40 years and individual blocks can be lifted and replaced. Concrete driveways last 30–40 years but are expensive to repair when cracked. Gravel driveways are the most cost-effective to maintain long-term.

When Is It Worth Repairing?

For isolated cracks and sunken areas, repair is almost always the right call — it's a fraction of the replacement cost and looks perfectly fine when done well. Full replacement makes sense when the base layer has failed (drainage issues, widespread cracking across the entire area) or when you're changing the material entirely.

Tarmac, Block Paving, Gravel, and Concrete: How Material Affects Repair

The type of driveway you have makes a big difference to both repair options and costs. Tarmac (asphalt) is the most common choice in the UK and relatively cheap to patch or resurface — cracks and potholes can be filled without replacing the whole surface. Block paving is highly repairable because individual blocks can be lifted and relaid, though weed growth and sunken areas need periodic attention. Gravel is the lowest-maintenance option — topping up costs very little and drainage is excellent. Concrete is the most durable surface but also the hardest to repair neatly; cracks in concrete are difficult to disguise and full replacement is expensive. Your choice of material also affects planning rules — if you're replacing an existing driveway, you may need to include permeable surfacing to comply with permitted development rules introduced in 2008.

Signs Your Driveway Needs Replacing

Widespread cracking across the surface — isolated cracks are repairable, but a network of cracks across the entire driveway usually means the sub-base has failed.
Large sunken or uneven areas — significant dips or pooling water indicate a sub-base issue that patching alone won't resolve long-term.
Potholes forming regularly — if new potholes keep appearing after repairs, the tarmac or concrete layer has deteriorated beyond the point of patching.
Drainage problems causing flooding — water not draining away properly can damage foundations and neighbouring properties, and may require a redesign with permeable surfacing.
Loose block paving across large areas — if blocks are rocking or shifting throughout (not just in one patch), the bedding layer beneath has likely failed.

Maintenance Costs and Long-Term Value

A well-maintained driveway adds genuine kerb appeal and can increase your property value by up to 10%, according to several UK estate agents. Tarmac driveways benefit from resealing every 3–5 years (£200–£500 for an average drive) to prevent water ingress and extend lifespan. Block paving should be re-sanded and sealed every few years to keep weeds at bay and maintain appearance. Gravel driveways need occasional topping up (£50–£150) and a weed membrane underneath saves ongoing maintenance. Under planning rules introduced in England in 2008, replacing a driveway with an impermeable surface larger than 5 square metres requires planning permission unless you include adequate drainage — so factor this into any replacement decision.

DIY vs Professional Driveway Repair

Driveways take a beating from weather, vehicle weight, and general wear. Some repairs are well within DIY territory and can save you hundreds, while others require professional equipment and expertise to get a result that lasts.

Safe DIY Repairs

Filling small cracks in tarmac with cold-lay repair compound — save £100–£200. Bags of cold-lay tarmac cost £8–£15 from B&Q or Wickes. Best applied in dry weather above 5°C for a lasting repair.
Re-levelling sunken block paving (lifting and re-laying individual blocks) — save £150–£300. Requires a flat-head screwdriver to lift blocks, plus sharp sand to re-level the bed underneath. A satisfying weekend job.
Topping up and raking gravel driveways — save £80–£150. Decorative gravel costs around £50–£80 per bulk bag. Rake to redistribute and top up thin patches annually.

Always Hire a Professional

Full tarmac resurfacing (£1,500–£4,000) — Requires specialist plant (roller, hot tar sprayer) and must be laid at the correct temperature. Poor DIY attempts peel and crack within months.
Resin-bound driveway installation or repair (£2,500–£6,000) — Resin driveways need precise mixing ratios and must be laid quickly before the resin cures. Professional installation ensures proper drainage compliance (SuDS).
Structural repair to a sinking or cracked concrete driveway (£2,000–£5,000) — May indicate subsidence or poor sub-base — needs professional assessment. Concrete work requires formwork, reinforcement, and correct curing.

If your driveway connects to a public road, note that you may need a dropped kerb — this requires local council permission and is not a DIY job.

Frequently Asked Questions

Is it worth repairing a driveway?

Yes, for isolated cracks, sunken areas, and surface-level damage. Targeted repairs cost £100–£800 versus £2,000–£8,000 for full replacement. Only replace the whole driveway if the base layer has failed or damage is so widespread that piecemeal repair isn't viable.

How much does driveway repair cost in the UK?

Driveway repairs vary by material. Tarmac crack repairs cost £100–£300. Block paving repairs run £200–£800. Full driveway replacement for an average home costs £2,000–£8,000 depending on material chosen.

How long should a driveway last?

Tarmac driveways last 20–30 years. Block paving 20–40 years. Concrete 30–40 years. Gravel is the most cost-effective long-term with easy ongoing top-ups. Base preparation quality is the single biggest factor in longevity.

My driveway has cracked — do I need to replace the whole thing?

Usually not — isolated cracks are surface issues and repairable. Only widespread cracking across the whole surface, or cracking caused by base failure (often with drainage issues), needs a full replacement. Get two or three opinions from reputable local contractors.

Do I need planning permission to replace my driveway in the UK?

If your new driveway is over 5 square metres and uses impermeable surfacing (standard tarmac or concrete), you’ll need planning permission unless the rainwater drains to a permeable area within your property. Permeable surfaces like resin-bound, permeable block paving, or gravel are exempt from this requirement.

What is the cheapest type of driveway to install in the UK?

Gravel is the most affordable driveway surface, typically costing £30–£60 per square metre installed. Tarmac comes next at £40–£80 per sqm. Block paving ranges from £60–£120 per sqm, while resin-bound is the most expensive at £60–£150 per sqm depending on the aggregate chosen.

How long does a tarmac driveway last before it needs replacing?

A well-installed tarmac driveway should last 15–25 years in the UK climate. Lifespan depends on the quality of the sub-base, drainage, and how much heavy vehicle use it gets. Applying a sealant every 3–5 years can significantly extend its life and improve appearance.
