Tarmac is one of the most practical driveway surfaces in the UK. It is smooth, hard wearing and quick to lay, and it usually costs less than block paving or resin. That combination makes it a popular choice for homeowners who want a dependable drive without a premium price.
At JPD Landscaping & Building Services, we have installed tarmac driveways across South East London for over 15 years. This guide explains what a tarmac driveway really costs, what pushes the price up, how it compares with other surfaces, and what a typical project looks like.
Average Tarmac Driveway Cost
A standard tarmac driveway typically costs between £60 and £80 per square metre, including the base. The final figure depends on the size of the drive and how much groundwork it needs.
The table below shows what that rate means for common driveway sizes.
| Driveway Size | Approximate Area | Estimated Cost |
| Small single car | 15m² | £900 to £1,200 |
| Single car | 20m² | £1,200 to £1,600 |
| Two cars | 30m² | £1,800 to £2,400 |
| Large driveway | 40m² | £2,400 to £3,200 |
| Extra large driveway | 50m² | £3,000 to £4,000 |
These figures assume reasonably straightforward ground. Removing an old surface, drainage and awkward access can all change the final price, and we cover each of them below.
What the Price Includes
A good quote covers the whole build, not just the black surface you see at the end. A tarmac driveway is made in layers, and each layer matters.
- Excavation: digging out the existing surface or soil to the required depth.
- Sub-base: a compacted stone foundation that carries the weight of vehicles.
- Base course: the lower, coarser layer of tarmac that gives the drive its strength.
- Surface course: the finer top layer that gives the smooth finish.
- Edging and finishing: neat edges and a proper finish where the drive meets the road, house or borders.
- Waste removal: taking away the spoil and any old surface.
A tarmac driveway is typically laid at 60mm to 100mm in total, combining the base course and the surface. A much cheaper quote often means a thinner build or a weaker base, and those are the shortcuts that lead to cracks and potholes.
Why the Base Matters Most
It is tempting to think of tarmac as a simple surface, but the layers beneath it do most of the work. The sub-base spreads the weight of vehicles across the ground, so that no single point takes too much load. If that foundation is too shallow, or has not been compacted thoroughly, the ground moves under the drive and the tarmac above it follows.
The same principle applies to every paved surface we build. Our guide on how to lay a patio explains why compaction and sub-base depth come first, and a driveway simply asks more of that base because of the loads it carries. When you compare quotes, ask what depth of sub-base is included and how it will be compacted, because that tells you far more than the price per square metre.
What Pushes the Cost Up
Two driveways of the same size can cost very different amounts. These are the factors that make the biggest difference.
Groundwork and Removing the Old Surface
A driveway carries a lot of weight, so it needs a properly compacted base. Digging out the ground to the right depth takes time and machinery. If you are replacing old tarmac, concrete or block paving, breaking it out and taking it away adds to the total.
Sloped or soft ground can add further work, because the base needs extra attention to stay stable under vehicles. If your front garden has a significant level change, the groundwork may involve a retaining wall before any surface goes down.
Drainage
Standard tarmac is not permeable, so rainwater runs off the surface rather than through it. That means the drive needs a sensible plan for where the water goes, such as falls towards a lawn or border, a drainage channel or a soakaway. Planning that properly can add to the cost, but it is essential, because water that sits on a tarmac surface causes damage over time. Our guide on patio drainage problems and fixes explains how falls and outlets behave in practice, and the same thinking applies here.
Access for Machinery and Materials
Tarmac is delivered hot and laid with machinery, so access matters. A narrow side passage or a tight site can slow the work and add to the cost, because the material may need to be moved by hand.
Edging, Borders and Finishing Details
A simple tarmac drive is the cheapest. Adding brick or block borders, kerbs, steps or decorative edging increases the price, although it can lift the look of the whole driveway. Our guide to patio edging ideas covers setts, brick and metal edging, and much of it works just as well alongside a tarmac drive.
Planning Rules for Tarmac Driveways
Because standard tarmac is not permeable, the front garden rules matter. In England, paving more than 5 square metres of front garden with a non-permeable surface usually needs planning permission, unless the rainwater drains to a lawn, a border or another permeable area within your property.
That does not rule tarmac out. A drive designed with the right falls, so that the water runs to a planted area or a soakaway, can stay within the rules. We check each site and advise case by case.
Other checks apply too. A new dropped kerb needs separate council approval, and properties in conservation areas, listed buildings and flats can have extra restrictions. If you would like the full picture, our guide on planning permission for driveways works through each situation. This is general guidance rather than legal advice, so confirm your own situation with your local council.
Tarmac vs Other Driveway Surfaces
Tarmac sits at the lower end of the cost range, and it compares well on price with almost every alternative.
| Surface | Typical Cost per m² | Key Point |
| Tarmac | £60 to £80 | Low cost, smooth and quick to lay, but plain |
| Gravel with base and grid | £70 to £90 | Free draining, but needs topping up |
| Block paving | £100 to £130 | Strong, attractive and easy to repair |
| Resin bound | £100 to £130 | Smooth, seamless and permeable |
If budget is the priority, tarmac offers a lot for the money. If looks and easy repairs matter more, block paving or resin may be worth the extra. Our comparison of resin bound and block paving driveways looks at those two in more detail, and our guide to block paving driveway costs shows what the higher price buys.
The Advantages of a Tarmac Driveway
Tarmac has stayed popular for good reasons.
- Low cost. It is one of the most affordable hard surfaces, and the installation is quick, often finished in a day or two once the base is ready.
- Smooth and durable. Properly laid, it handles everyday vehicles and heavier loads very well.
- Easy to keep clean. There are no joints, so weeds have nowhere to take hold, and a sweep is usually enough.
- Comfortable to use. The smooth surface suits prams, bins, bikes and wheelchairs far better than loose gravel.
The Disadvantages of a Tarmac Driveway
It is only fair to be clear about the downsides too.
- A plain look. Tarmac is practical rather than decorative, and it does not offer the colours and patterns of block paving or resin.
- Cracks, potholes and fading. Over time, the surface can crack, develop potholes, and fade from black to grey, particularly if the base was weak.
- Visible repairs. A patch repair usually shows against the original surface, because new tarmac looks different from weathered tarmac.
Most of these issues come down to how well the driveway was built, which is where the next section matters.
Why Tarmac Driveways Fail
Tarmac driveways rarely fail because of the surface itself. They fail because of what is underneath and how it was laid. In our experience, three mistakes account for most problems, and they often appear together.
- A thin or poorly compacted sub-base. If the base is not deep and firm enough, the surface sinks and cracks under the weight of vehicles.
- Laying in cold or wet weather. Tarmac needs to be laid and rolled while it is hot, and cold or wet conditions can stop it bonding properly.
- Poor drainage. Water that pools on the surface or seeps into the base weakens it and leads to potholes.
All three are hidden once the surface is down, which is why a low price can look fine on day one and fail within a few years. A properly built driveway costs a little more at the start, but it avoids the much higher cost of ripping it up and starting again.
Resurfacing or Starting Again?
When an old tarmac drive looks tired, many homeowners ask whether a new layer on top is enough. The honest answer depends on why the drive looks the way it does. If the surface is faded or lightly worn, but the drive is flat, solid and drains properly, a new surface layer can work well.
If the drive has widespread cracks, sunken areas or standing water, the problem is almost always the base, and covering it simply hides the fault for a short time. In that case, digging out and rebuilding is the better investment. A site visit is the only reliable way to tell the difference, which is why we look at the base and the falls before suggesting either route.
How Long Does a Tarmac Driveway Last?
A well built tarmac driveway can last many years, and the difference between a long life and a short one is almost always the base. A driveway laid on a deep, compacted sub-base, with sensible drainage and a proper thickness, will stand up to everyday use far longer than a thin, hurried build.
Simple care helps too.
- Keep the surface clear of debris, so water can run off freely.
- Clean up oil and fuel spills promptly, because they can soften the surface.
- Repair small cracks early, before water gets in and widens them.
- Avoid parking heavy loads on the edges, where the surface is most vulnerable.
Project Example: Replacing a Cracked Tarmac Drive
One of our typical projects involved a South East London home with an ageing tarmac driveway that had cracked and sunk in several places.
| Detail | Specification |
| Driveway size | About 30m² |
| Existing surface | Old tarmac, cracked and uneven |
| Problem | Thin base and standing water near the garage |
| Our fix | Full dig out, new compacted sub-base and new tarmac |
| Drainage | Falls reset so water runs to a planted border |
The owners were tempted by a cheap resurfacing quote, but the cracks and puddles pointed to a failed base rather than a worn surface. We broke out the old tarmac, excavated to the right depth, and laid a compacted sub-base. We then laid a base course and a surface course, giving a total thickness within the usual 60mm to 100mm range.
We also reset the falls so that rainwater now runs to a planted border instead of pooling by the garage. The finished driveway is smooth, flat and free of puddles. At around £60 to £80 per square metre, it cost far less than paving would have, and it was built on a base that should last. It is a good example of why the groundwork matters more than the surface.
How to Get an Accurate Quote
A per square metre price is useful for early budgeting, but the only reliable number comes from a site visit. When you ask for a quote, have these details ready.
- The approximate size of the driveway and how many vehicles it needs to hold.
- What is there now, and whether it needs to be removed.
- Whether the site slopes, and whether there is an existing dropped kerb.
- Any drainage concerns, such as puddles or water running towards the house.
- Whether you would like borders, kerbs or other edging details.
A good quote should itemise the groundwork, the base, the tarmac layers, the edging and the waste removal, so you can compare quotes fairly. If the driveway is part of a wider project, our guide on how much it costs to landscape a garden shows how it fits into the overall budget, and our explanation of hard landscaping helps you plan the drive, paths and patio together.
Frequently Asked Questions
How much does a tarmac driveway cost in the UK?
A standard tarmac driveway typically costs between £60 and £80 per square metre, including the base. A single car drive of about 20 square metres would be roughly £1,200 to £1,600, and larger drives cost more.
Is tarmac cheaper than block paving?
Yes. Tarmac typically costs £60 to £80 per square metre, compared with £100 to £130 for block paving or resin bound. It is also usually quicker to install.
How thick should a tarmac driveway be?
A tarmac driveway is typically laid at 60mm to 100mm in total, combining the base course and the surface course, on top of a compacted sub-base. A heavier use drive may need more.
Do I need planning permission for a tarmac driveway?
Standard tarmac is not permeable. In England, paving more than 5 square metres of front garden with a non-permeable surface usually needs planning permission, unless the water drains to a lawn, border or other permeable area. A new dropped kerb also needs separate council approval. Check with your council.
How long does a tarmac driveway last?
A well built tarmac driveway can last many years. The lifespan depends far more on the quality of the sub-base, the thickness and the drainage than on the surface itself.
Why has my tarmac driveway cracked?
Cracks usually point to a thin or poorly compacted base, poor drainage, or tarmac laid in unsuitable weather. Small cracks can be repaired early, but widespread cracking and sinking often means the base needs rebuilding.
Can tarmac be repaired?
Yes, small cracks and potholes can be patched, but repairs usually show against the original surface. If the base has failed, patching is only a short term fix.
Is it better to resurface or replace a tarmac drive?
If the drive is flat, solid and draining well, and only the surface is worn, resurfacing can work. If there are widespread cracks, sunken areas or standing water, the base has usually failed, and a full rebuild is the better investment.
