Driveway Quote - How to Spot the Cowboys Before They Start
Driveway quotes are where cowboys thrive. Here's what a proper quote includes, UK costs for 2026, and the details that separate the good from the dodgy.
Driveways attract cowboys like nothing else in the building trade. There's something about tarmac and block paving that brings out the chancers - doorstep sellers, "leftover materials" merchants, and firms that vanish after three months when the surface starts cracking.
The good news? A dodgy driveway company is actually easy to spot, if you know what a proper quote looks like. And once you know what to look for, you'll never fall for a cheap price that costs you double in the long run.
What a good driveway quote looks like
A driveway seems simple. Dig it out, put something down, done. But the work underneath the surface is what determines whether it lasts two years or twenty. A proper quote covers every layer.
Exact area in square metres - not "the front drive" or "as discussed." The contractor should measure the area and state it clearly. A typical UK driveway is 40-60m², but yours might be bigger or smaller. The price depends entirely on the area, so it needs to be right.
Existing surface removal - what's there now? Concrete, old tarmac, gravel, grass? Removing it costs money. Breaking up an old concrete drive and taking it away is a different job to scraping off gravel. The quote should say what's being removed, to what depth, and how it's being disposed of.
Excavation depth - how deep are they digging? For most driveways, you need to excavate 200-300mm below the finished surface level to make room for the sub-base and the surface material. If the quote doesn't mention excavation, the contractor might be planning to lay the new surface on top of whatever's there. That rarely ends well.
Sub-base type and depth - the sub-base is the compacted gravel layer that sits underneath the visible surface. It's the structural foundation of the driveway. Without it, the surface will crack, sink, and fail. A proper quote specifies the material (usually MOT Type 1, a specific crushed stone mix that compacts firmly) and the depth (typically 150-200mm for cars, 250mm+ if you're parking anything heavier). This is the single most important thing in any driveway quote. If it's not there, walk away.
Edging and restraints - block paving needs an edge. Without it, the blocks at the edges gradually spread apart and the whole surface loosens. Edging restraints (concrete kerbs or purpose-made edge blocks) should be listed with their type and dimensions. For tarmac, a firm edge is still needed to stop it crumbling at the sides.
Surface material and specification - what are you actually getting on top? For block paving, the quote should name the manufacturer, block type, size, thickness, colour, and laying pattern. For tarmac, it should state the number of layers and the total thickness (a proper tarmac drive has a base course and a surface course - two separate layers). For resin bound, it should name the aggregate type and resin brand.
Drainage and falls - water has to go somewhere. The driveway needs a fall (a slight slope, usually 1:80 or steeper) directing water towards a drain or the road. If there are no existing drains in the right place, new drainage needs adding. This is not optional - ponding water damages any surface and causes problems in freezing weather.
Manhole covers - if there are manholes (inspection covers for underground drains) in your driveway, they'll need replacing or adjusting to sit flush with the new surface. Recessed manhole covers (the type with a tray that you fill with the same material as the driveway, so they blend in) cost £60-£150 each. If they're not in the quote, check.
What it should cost - 2026 UK prices
Driveway costs are almost always quoted per square metre. Here's what to expect for an installed price including sub-base, edging, and labour.
| Surface type | Cost per m² (2026) | 50m² driveway total |
|---|---|---|
| Gravel (loose, contained) | £40–£60 | £2,000–£3,000 |
| Tarmac (two-coat) | £50–£70 | £2,500–£3,500 |
| Block paving (standard) | £70–£120 | £3,500–£6,000 |
| Resin bound | £60–£90 | £3,000–£4,500 |
| Indian sandstone | £80–£130 | £4,000–£6,500 |
| Concrete (plain) | £50–£80 | £2,500–£4,000 |
| Pattern imprinted concrete | £60–£100 | £3,000–£5,000 |
These prices assume reasonable access and straightforward ground conditions. Steep slopes, poor ground, restricted access, or a long distance from the road to the drive will all push costs up.

Red flags - the ones that cost people thousands
The doorstep tarmac seller
This is the classic. A van pulls up. Friendly bloke knocks on the door. "We've been working down the road and we've got some leftover tarmac. Normally it'd be three grand, but we can do your drive today for twelve hundred. Cash."
No. Never. This is the oldest scam in the driveway trade. The "tarmac" is usually a thin scrape of waste material rolled over your existing surface with no sub-base, no edging, and no drainage. It looks acceptable for about six weeks, then it cracks, sinks, and falls apart. By then, the van is long gone and the phone number doesn't work.
A legitimate driveway company does not go door-to-door offering leftover materials. Ever. For more on why cash payments are risky, see our guide on paying your builder cash.
No sub-base mentioned
If the quote doesn't mention the sub-base - the compacted gravel layer underneath the surface - the contractor is either planning to skip it or assuming you know it's included. Neither is acceptable. The sub-base is what holds everything up. Without it, cars will cause the surface to deform, crack, and break apart.
Ask directly: "What sub-base are you using, and how deep is it?" If they can't answer clearly, find someone else.
No drainage provision
A driveway without drainage is a puddle waiting to happen. The quote should show that the contractor has thought about where water goes. That might be a fall towards the road, channel drains across the bottom of the drive, or a soakaway (an underground chamber that lets water drain slowly into the ground). If none of these are mentioned, the contractor hasn't planned for rainwater.
Quoting without measuring
"About fifty square metres, should be around four grand." That's not a quote. That's a guess. A proper contractor measures the area, checks the access, looks at the existing surface and ground conditions, and checks the drainage before giving you a price. If they haven't been to your house with a tape measure, the price is fiction.
Wanting full payment upfront
No legitimate driveway company needs all the money before they start. A deposit of 10-20% to secure materials and book the work is reasonable. Anything more than 25% upfront is a red flag. And never pay the full balance until the work is finished and you're happy with it. We've written more about deposit risks in our guide to builders wanting large deposits.
"We had leftover materials"
Whether it's tarmac, block paving, or resin, the "leftover materials" line is almost always a lie. Driveway materials are ordered to specification for each job. Legitimate contractors don't have surplus stock sitting in a van looking for somewhere to dump it. If someone offers you a bargain because of "leftovers," they're either using inferior materials or it's a scam.
What's often missing from driveway quotes
Planning permission
Here's the big one most people don't know about. If your new driveway uses a non-permeable surface (one that doesn't let water soak through - standard tarmac, concrete, or solid block paving) and it's more than 5 square metres in your front garden, you need planning permission.
This rule came in under the Town and Country Planning (General Permitted Development) Order 2015 to reduce flooding from paved-over front gardens. Permeable surfaces (gravel, permeable block paving with wider joints, resin bound) don't need permission because water can drain through them.
Your driveway contractor should tell you about this. If they don't mention it, they either don't know (which is worrying) or they're hoping you won't ask (which is worse).
Existing surface disposal
Breaking up and removing an old concrete drive costs £500-£1,500 depending on thickness and area. Old tarmac is cheaper to remove but still needs disposing of properly. If the quote says "preparation" without specifying what that means, check whether it includes actually getting rid of the old surface.
Manhole cover replacement
If you've got drain inspection covers in your driveway, they need to sit flush with the new surface. Standard steel covers look terrible in a block-paved drive. Recessed covers (ones with a tray that holds matching blocks or slabs) cost £60-£150 each but make a big difference to the finished look. If they're not in the quote, you'll either get ugly steel covers or an unexpected extra.
Edging restraints
Block paving absolutely requires edge restraints - usually concrete haunching (a wedge of concrete along the outer edge) or purpose-made kerb blocks - to stop the blocks spreading and loosening over time. This is not optional. If the quote mentions block paving but not edge restraints, the blocks will shift within a couple of years and you'll need the whole thing re-laying.
Weed membrane
A weed membrane (also called geotextile fabric) goes between the sub-base and the surface to stop weeds growing up through the joints. It's cheap - about £1 per m² - but it makes a real difference over time. Without it, you'll be pulling weeds out of your block paving or gravel every summer. It's a small detail that separates a professional job from a bodge.
How to compare driveway quotes properly
Step 1: Check the specification layers
Every quote should describe the driveway from the bottom up: excavation depth, sub-base material and depth, surface material and thickness, edging type. If any layer is missing, the price is incomplete.
Step 2: Confirm the total area
Make sure all quotes are based on the same measured area. A 10% difference in area means a 10% difference in price, and it has nothing to do with value.
Step 3: Ask about drainage
What drainage is included? Falls to the road? Channel drains? Soakaways? If one quote includes proper drainage and another doesn't, the cheaper one isn't really cheaper - it's just incomplete.
Step 4: Check for planning permission
If your front driveway is over 5m² and you're using a non-permeable surface, ask whether planning permission is needed. If the contractor doesn't mention it, that's a concern.
Step 5: Look at the payment terms
Reasonable payment terms: 10-20% deposit, staged payments tied to completed work, final 10-20% on completion. Unreasonable terms: 50% upfront, cash only, full payment before the work starts. The payment terms tell you a lot about the company. If you want to understand what fair payment schedules look like, read our guide on large deposit requests.
Step 6: Verify the contractor
Check if they're a member of a trade body - the British Association of Landscape Industries (BALI), the Marshalls Register (for Marshalls block paving installers), or Checkatrade-registered with genuine reviews. Ask for photos of completed work. Ask for a reference you can call. Driveway work attracts more rogues than almost any other trade, so due diligence is worth the effort.
The bottom line
A driveway is one of the first things people see when they visit your home. It's also one of the easiest things to get wrong. The difference between a drive that lasts twenty years and one that cracks after two comes down to what happens underneath the surface - and that's exactly the stuff that dodgy contractors skip.
