Tarmac driveways: pros, cons and what to know before you lay one

A tarmac driveway is one of the cheapest hard drives to lay, and cars can use it within 48 hours. It is also impermeable, softer in summer heat and shorter-lived than concrete or block paving. We cover the pros and the downsides, how long each build lasts, tarmac against other surfaces, the front drive drainage rule, and whether you can lay it yourself.

What is a tarmac driveway?

Tarmac is the everyday name for the asphalt used on UK drives: crushed stone coated in bitumen, laid hot and rolled flat. A drive is built in layers. The smooth top layer you drive on is the wearing course, a stronger binder course sits under it, and the longest-lasting builds add a base layer below that.

All of it sits on a compacted sub-base of crushed stone, usually 150 mm of Type 1. The sub-base carries the weight, so two drives that look the same on the day they are finished can last 5 years or 25.

Pros of a tarmac driveway

Tarmac wins on price, speed and upkeep. Its main advantages:

• Price. Standard tarmac costs £45 to £90 per m² fitted, below block paving at £80 to £120 and starting under plain concrete at £55.
• Speed. A drive takes 1 to 2 days to lay, and cars can use it after 24 to 48 hours.
• One smooth surface. There are no joints, so weeds have nowhere to root and a stiff brush keeps it clean.
• Strength. Laid on a proper sub-base, it takes daily car traffic and keeps its grip in the wet.
• Easy repairs. A failed area is cut out and patched rather than relaid, at £180 to £480 for a patch of 1 to 3 m².

Downsides of a tarmac driveway

Most of tarmac's weaknesses come from the bitumen that binds it and from its sealed surface.

• It softens in heat. On a hot day the surface can mark under tyres, stands and heavy loads, and freeze-thaw cycles open up cracks in a worn drive over winter.
• Oil stains stick. Oil dripped from a car soaks into the surface and is hard to shift completely.
• It looks plain. Black is standard, and colour costs more: a 50 m² two-layer drive with a coloured top layer runs £6,500 to £10,500, against £4,200 to £6,800 in black.
• Edges break away without support. Tarmac needs kerbs or blocks along its sides, which cost £20 to £50 per metre fitted.
• It wears out sooner. Tarmac lasts 15 to 25 years against 25 to 40 for concrete, and it needs resurfacing in the end.
• Water runs off it. Standard tarmac is impermeable, so a front drive has to send its rainwater somewhere, which brings in the planning rule.

How long a tarmac driveway lasts

A tarmac drive laid on a proper sub-base lasts 15 to 25 years. The build decides where in that range it lands, and a surface laid over the old drive, or by hand, lasts far less.

Ageing starts to show at 8 to 12 years. A cosmetic recoat then adds 5 to 8 years, and small failures are patched as they appear.

What shortens a drive is almost always underneath. A thin or badly compacted sub-base shows up as cracks, dips and potholes, and edges with nothing holding them crumble first, whatever the surface cost.

What a tarmac driveway costs

A medium drive of 50 to 60 m² costs £2,500 to £5,000 in standard tarmac in 2026. The layers and the sub-base decide what a tarmac driveway costs more than the area does: on 50 m², an overlay runs £1,800 to £3,500 and two layers on a new sub-base £4,200 to £6,800.

London tarmac drives cost £60 to £95 per m² fitted, and quotes across London and the South East typically run 20 to 30 percent above the rest of the UK.

Tarmac against concrete, block paving and resin

Tarmac is the cheapest hard surface to start with, gravel apart. It gives up lifespan to concrete and block paving, and drainage to gravel and resin bound.

Tarmac or concrete

Tarmac is cheaper than concrete at the bottom of the range, £45 per m² against £55, but the two ranges overlap. A medium drive of 50 to 60 m² costs £2,500 to £5,000 in tarmac and £3,000 to £4,400 in plain concrete.

Concrete lasts longer, 25 to 40 years against 15 to 25, but it needs 7 to 28 days before regular use, where tarmac takes cars after 24 to 48 hours.

Tarmac or block paving

Standard block paving costs £80 to £120 per m² fitted, and premium blocks up to £150. On a medium drive of 50 to 60 m², that is £4,400 to £6,600 in blocks against £2,500 to £5,000 in tarmac.

Blocks last longer, at 20 to 30 years, come in more colours and patterns, and a sunken area can be lifted and relaid at £40 to £70 per m². They also need re-sanding every 2 to 3 years at £5 to £12 per m², where tarmac has no joints to fill.

Tarmac or resin

A resin driveway costs £60 to £130 per m², above tarmac at the bottom of the range, and lasts about as long, at 15 to 25 years. The difference is drainage: resin bound lets water through, so a front drive in resin needs no lawn, border or planning application in England, where standard tarmac does. Resin bonded, the scatter-coat version, is not permeable.

Do you need planning permission for a tarmac driveway?

In England, a new front drive over 5 m² needs planning permission if it is impermeable and the rainwater has no permeable area to run to, under the Planning Portal's rules for paving a front garden. Standard tarmac counts as impermeable, because water runs off it rather than through it. Permeable surfaces, porous asphalt among them, need no permission at any size.

The routes for a tarmac front drive over 5 m² in England:

1. Lay it to fall towards a lawn, border or rain garden inside the boundary, so the water soaks away there.
2. Collect the water in a channel drain at £45 to £85 per metre and send it to a soakaway, which adds £450 to £950.
3. Lay porous asphalt instead, at £70 to £120 per m², which lets the water through.
4. Apply for planning permission. A householder application in England costs £272 to £548 from 1 April 2026, depending on how the council classes the work.

Laying a front drive without an application is a permitted development right, and only houses have it. A flat or maisonette, some converted houses, and any home under an Article 4 direction or a planning condition that removes the right need the council's say before a new front surface goes down.

Wales and Scotland are stricter than England. In Wales, Welsh Government guidance applies the rule to any new or replacement hard surface at the front, and only repairs or replacement of up to 5 m² are exempt. Scotland's Class 3C, set out in Circular 1/2024, covers any hard surface between the house and a road with no size threshold, and a drive in a conservation area or within the grounds of a listed building needs permission whatever it is made of. Northern Ireland's Class E matches England's 5 m² threshold.

Planning covers the drive, not the pavement. Crossing a pavement to reach it needs a dropped kerb, applied for through the local council. It costs £800 to £3,500 and can take 4 to 12 weeks, so apply before the tarmac is booked.

How a tarmac driveway is laid

A new drive takes 1 to 2 days on site, and the work runs in this order:

1. The old surface is dug out to 250 to 300 mm, and the spoil goes in a skip.
2. Edging goes in: concrete kerbs or blocks set along the sides to hold the tarmac.
3. 150 mm of Type 1 crushed stone is laid and compacted in two passes, shaped to the finished fall.
4. The binder course goes down hot at about 50 mm and is rolled.
5. The top layer, the wearing course, goes on at 25 to 30 mm and is rolled smooth.
6. The drive is left to harden: cars can use it after 24 to 48 hours, and heavy vehicles such as delivery lorries after 7 days.

The fall matters as much as the layers. A drop of about 1 in 60 across the surface, 1 cm for every 60 cm, sends the water towards a lawn, border or drain rather than the house.

Because heavy vehicles have to stay off new tarmac for 7 days, a drive laid as part of a renovation goes near the end of the order of works, after the skips, the scaffold and the delivery lorries have finished.

Can you lay a tarmac driveway yourself?

You can lay tarmac yourself, but not the kind a drive is built from. Driveway tarmac is hot-mix, laid at around 150°C with specialist heating and laying equipment, and it has to be spread, levelled and rolled while it is still hot. That is work for a crew of 3 to 4 and a roller.

DIY tarmac means cold-lay: bagged tarmac spread at air temperature and compacted with a vibrating plate of 100 kg or more. A plate that size hires at £80 to £100 a day or costs £1,500 or more to buy. Cold-lay suits a pothole, a garden path or a small parking space used now and then. The drainage rule applies whoever lays the drive.

The plant for a proper dig-out can be hired, but it adds up before any tarmac arrives. A 1.5 tonne mini-digger runs £180 to £280 a day, a vibrating roller £85 to £140 a day, and a 16-yard skip for the spoil £450 to £750.

Hiring also buys a written guarantee. A DIY drive that fails has no comeback.
