Installing a small one-car asphalt driveway in the UK typically costs around £1,800 to £3,500 for a complete new installation. For a fairly standard driveway of around 15 to 20 square metres, a sensible working budget is approximately £2,000 to £3,000.
The finished asphalt itself is only part of the cost. A proper driveway also needs excavation, a compacted sub-base, secure edging and suitable drainage. Consequently, converting a lawn or front garden into parking usually costs considerably more than laying fresh asphalt over an existing sound driveway.
As a rough guide, a complete new asphalt driveway often works out at around £80 to £140 per square metre for a small one-car area once groundwork is included. Resurfacing an existing sound base can be considerably cheaper.
Typical small asphalt driveway cost
A small residential driveway normally measures between 12m² and 25m², depending on the available frontage and vehicle size.
Quick cost summary
| Small asphalt driveway project | Typical UK cost |
|---|---|
| Very small 12m² driveway | £1,500 to £2,300 |
| 15m² one-car driveway | £1,700 to £2,600 |
| 20m² one-car driveway | £2,000 to £3,200 |
| 25m² larger single driveway | £2,300 to £3,700 |
| New asphalt driveway | £80 to £140 per m² |
| Asphalt resurfacing | £40 to £70 per m² |
| Excavation | £20 to £40 per m² |
| New sub-base | £20 to £40 per m² |
| Block-paved edging | £30 to £70 per linear metre |
| Drainage channel | £50 to £100+ per linear metre |
| Small soakaway | £600 to £1,500+ |
| Dropped kerb | £1,500 to £3,500+ |
These prices provide a planning guide rather than a fixed tariff. Access, existing ground conditions and drainage can easily move a small driveway towards the upper end.
How much does a 15m² asphalt driveway cost?
A compact 15m² driveway may be suitable for one small or medium-sized car.
Typical cost
£1,700 to £2,600
A straightforward project might include:
- removing turf or an old surface
- excavating the driveway
- installing a compacted sub-base
- fitting edging
- laying asphalt
- compacting the surface
However, drainage and a new dropped kerb would normally increase the cost.
Because 15m² is a relatively small area, the contractor may charge a minimum project rate rather than simply multiplying the area by a square-metre figure.
How much does a 20m² asphalt driveway cost?
Around 20m² is a useful benchmark for a one-car UK driveway.
Typical cost
£2,000 to £3,200
Current UK market pricing puts a typical 20m² single-car tarmac or asphalt driveway at roughly £2,200 for materials and labour, although complete excavation and drainage work can push the final figure higher.
A 20m² driveway may measure roughly:
- 3 metres x 6.5 metres
- 3.5 metres x 5.7 metres
- 4 metres x 5 metres
The exact dimensions should leave enough room to park the vehicle without blocking paths, doors or the pavement.
How much does a 25m² asphalt driveway cost?
A 25m² driveway provides more comfortable parking space for a larger vehicle.
Typical cost
£2,300 to £3,700
This size may also allow room for:
- easier door opening
- bins
- a narrow pedestrian path
- decorative edging
- planted borders
Although the total cost rises, the price per square metre may begin to fall slightly because the contractor can spread setup and material delivery charges across a larger area.
Why can a small asphalt driveway be expensive per square metre?
Small driveway jobs carry many of the same fixed costs as larger installations.
The contractor may still need:
- a mini digger
- compactor
- roller
- asphalt delivery
- two or more workers
- grab-lorry or skip collection
- cutting equipment
- drainage materials
- several visits to the site
Therefore, a 15m² driveway does not cost 30% of the price of a 50m² driveway simply because it covers 30% of the area.
For example, a larger driveway might work out at £80 to £100 per m², while a very small driveway could effectively cost £110 to £140 per m².
What does a new one-car asphalt driveway include?
A properly constructed asphalt driveway starts well below the finished surface.
A standard installation may involve:
- removing grass, paving or the existing surface
- excavating to the required depth
- removing soil and rubble
- preparing the formation
- installing geotextile membrane where appropriate
- laying a compacted sub-base
- installing kerb or block edging
- fitting drainage channels
- laying a binder course
- installing the final asphalt surface
- compacting with a roller
- adjusting drain covers
- clearing the site
As a result, the visible black surface may account for less than half of the work.
Cost to excavate a small driveway
Excavation usually forms the first stage when converting a lawn or front garden.
Typical cost
£300 to £800
Alternatively, contractors may price excavation at roughly:
£20 to £40 per m²
The final cost depends on what they need to remove.
Soft soil is generally straightforward. By contrast, breaking out reinforced concrete or thick paving can require more machinery and disposal.
Cost of removing a lawn for a one-car driveway
Turning part of a front lawn into parking is a common small driveway project.
Typical excavation and clearance cost
£400 to £1,000
The contractor usually needs to remove:
- turf
- topsoil
- plants
- roots
- small landscaping features
Afterwards, they excavate further to create enough depth for the structural driveway layers.
Asphalt driveway sub-base cost
The sub-base carries the vehicle load and helps prevent future sinking.
Typical cost
£400 to £900 for a small driveway
MOT Type 1 aggregate is commonly used for conventional construction.
The contractor should compact it thoroughly rather than simply spreading stone into the excavation.
If the base is too thin or poorly compacted, the finished driveway may develop:
- tyre depressions
- cracks
- sunken areas
- standing water
- broken edges
Consequently, reducing the groundwork specification is rarely a good way to save money.
Asphalt driveway binder course cost
The binder course sits between the sub-base and the finished asphalt.
Typical cost
£300 to £700 for a small driveway
It helps spread vehicle loads and creates a strong foundation for the final surface layer.
Some simple resurfacing jobs may not need a completely new binder course if the existing asphalt remains structurally sound.
Asphalt surface course cost
The surface course creates the finished appearance.
Typical cost
£500 to £1,000 for a 15 to 20m² driveway
The asphalt normally arrives hot and needs laying and compacting quickly.
Because asphalt plants and delivery vehicles often have minimum charges, small driveways may cost considerably more per tonne of material than large commercial jobs.
New asphalt driveway versus resurfacing
One of the biggest pricing differences comes from whether you need a completely new driveway or simply a new surface.
New asphalt driveway
Typical cost
£80 to £140 per m² for a small project
This normally includes:
- excavation
- sub-base
- edging
- binder course
- final surface
A new build makes sense where the existing ground is unstable or no driveway currently exists.
Asphalt resurfacing
Typical cost
£40 to £70 per m²
Resurfacing may be possible if you already have a sound asphalt, tarmac or concrete base.
The contractor may:
- clean the existing surface
- cut out weak areas
- repair potholes
- apply bonding material
- lay a new surface course
For a 20m² driveway, resurfacing may therefore cost around £900 to £1,500.
However, resurfacing will not fix a collapsing foundation.
Can asphalt be laid over an old tarmac driveway?
Yes, if the existing driveway remains structurally stable.
This is often one of the most economical ways to improve an old driveway.
Before resurfacing, the contractor should check for:
- widespread cracking
- sinking
- loose edges
- potholes
- drainage problems
A few local defects can usually be repaired.
By contrast, widespread movement suggests that the old foundations may need removing.
Can asphalt be laid over concrete?
Sometimes.
Sound concrete can provide a strong base, although preparation matters.
Typical overlay cost
£40 to £75 per m²
The contractor may need to:
- clean the concrete
- repair cracks
- adjust levels
- apply a bonding coat
- install asphalt above
However, cracks or movement in the concrete can eventually reflect through the asphalt.
Therefore, badly damaged slabs may need breaking out instead.
Asphalt driveway edging cost
Good edging supports the surface and prevents the sides from crumbling.
Concrete kerb edging
£20 to £40 per linear metre
Block-paved edging
£30 to £70 per linear metre
Decorative stone edging
£40 to £100+ per linear metre
For a small driveway, block edging can make a noticeable visual difference without needing a large amount of material.
A typical single-car driveway might therefore spend £300 to £800 on edging.
Is block edging worth adding?
For many small asphalt driveways, yes.
A contrasting block border can:
- support asphalt edges
- define the parking area
- improve appearance
- separate asphalt from flower beds
- create a decorative entrance
Because the driveway itself is small, the additional cost can remain manageable.
Small driveway drainage cost
Drainage is particularly important where the driveway sits directly in front of the house.
Typical cost
£300 to £1,500+
Possible solutions include:
- linear channel drains
- soakaways
- directing runoff into a flower bed
- permeable strips
- porous asphalt
In England, a new or replacement front driveway can normally remain permitted development if the surface is permeable or if rainwater drains into a permeable area within the property. Traditional impermeable surfacing over 5m² may require planning permission if the water is not dealt with in this way.
Therefore, even a small one-car driveway needs drainage considered from the start.
Drainage channel cost
A linear channel drain is commonly installed across the front of the driveway or near the house.
Typical cost
£50 to £100+ per linear metre
For a driveway roughly three metres wide, the completed channel may cost around £250 to £600, depending on excavation and connection requirements.
Small driveway soakaway cost
A soakaway can receive surface water where the ground drains adequately.
Typical cost
£600 to £1,500+
The contractor may need:
- excavation
- soakaway crates or aggregate
- geotextile
- drainage pipe
- backfilling
Clay soils can make soakaways less effective.
Government guidance notes that permeable driveway construction will usually have roughly 200mm to 250mm of overall construction depth, with around 150mm of sub-base being typical in suitable conditions.
Porous asphalt driveway cost
Porous asphalt lets water pass through the finished surface.
Typical cost
£90 to £150+ per m² for a small driveway
The surface needs a suitable permeable sub-base beneath it.
Because the whole construction differs from conventional asphalt, simply using a porous top layer over an impermeable foundation will not create a genuinely permeable driveway.
Porous asphalt is specifically recognised in government guidance as one option for creating a permeable front driveway.
Cost of converting a front garden into a small asphalt driveway
A complete conversion may cost more than homeowners initially expect.
Typical cost
£2,500 to £5,000+
A typical project may involve:
- removing lawn and soil
- excavating
- waste disposal
- installing foundations
- drainage
- edging
- asphalt
- removing part of a wall or hedge
If the project also requires a dropped kerb, the total can increase significantly.
Dropped kerb cost for a small driveway
A new front driveway often needs legal vehicle access across the pavement.
Typical cost
£1,500 to £3,500+
The council or highway authority normally controls the process.
Government guidance states that creating new vehicle access across the footway requires permission from the local council, and the pavement may also need strengthening.
The price can rise where the work involves:
- utility covers
- street furniture
- trees
- unusual kerb arrangements
- traffic management
- wider crossings
In some locations, a dropped kerb can therefore cost as much as the driveway itself.
Cost to remove a small front wall
A front garden conversion may require a wider entrance.
Typical cost
£300 to £1,000
A small brick wall generally costs less to remove than a substantial masonry boundary.
If you want the contractor to rebuild pillars or create new ends, allow extra.
Cost to remove a hedge
Typical cost
£250 to £800
Large mature hedges and substantial roots may cost more.
The driveway contractor may also need to excavate old roots from beneath the future parking area.
Small asphalt driveway with block border cost
Combining asphalt with decorative paving creates a popular finish.
Typical cost for 20m²
£2,400 to £3,800
A typical project might include:
- black asphalt centre
- charcoal or brindle block border
- drainage channel
- neat pavement entrance
This generally costs less than paving the whole area with blocks while still providing some decorative detail.
Asphalt driveway with paved entrance apron
Some homeowners use block paving just at the driveway entrance.
Typical extra cost
£300 to £800
The paved area can:
- create visual contrast
- provide a stronger edge beside the pavement
- help disguise slight colour variation between asphalt batches
One-car asphalt driveway repair cost
Not every damaged driveway needs replacing.
Small crack repair
£100 to £250
Pothole repair
£150 to £400
Edge repair
£150 to £500
Several local patches
£300 to £800
Complete resurfacing
£900 to £1,500 for around 20m²
Repair generally makes sense when the foundation remains stable.
How much does it cost to widen a one-car driveway?
A small extension can make parking much easier.
Typical cost
£1,000 to £3,000+
For example, adding a one-metre strip along the side of a driveway may require:
- garden excavation
- new foundations
- edging
- asphalt
- resurfacing part of the existing drive
The per-square-metre price can be high because the added area is small.
Small asphalt driveway versus gravel
Gravel often provides the cheaper alternative.
Typical small gravel driveway
£1,200 to £2,200
Typical small asphalt driveway
£1,800 to £3,200
Gravel also has the advantage of being permeable.
However, asphalt requires less raking, does not move underneath tyres and generally provides a smoother surface.
Small asphalt driveway versus block paving
Asphalt
£1,800 to £3,200 for around 20m²
Block paving
£2,200 to £4,000+
Block paving costs more because contractors lay individual blocks by hand.
Nevertheless, it provides more colours, patterns and decorative options.
Small asphalt driveway versus resin
Asphalt
£1,800 to £3,200
Resin bound
£2,500 to £4,500+
Resin usually provides a more decorative finish but costs more.
Moreover, resin-bound installation quality depends heavily on the base and correct mixing.
Asphalt versus tarmac for a small driveway
Homeowners often use the terms asphalt and tarmac interchangeably.
Traditional tarmac technically used tar as a binder, whereas modern asphalt uses bitumen. Most modern UK domestic surfaces described casually as tarmac are actually bituminous asphalt materials.
For a homeowner, the quality of the specification matters more than terminology.
Ask the contractor about:
- sub-base depth
- binder layer
- final surface thickness
- compaction
- drainage
How thick should a small asphalt driveway be?
The exact specification depends on the ground and vehicle loading.
A typical domestic construction could include:
- around 100mm to 150mm of compacted sub-base
- around 40mm to 60mm binder layer
- around 20mm to 30mm surface course
Government permeable-driveway guidance similarly describes an overall build-up of roughly 200mm to 250mm in typical suitable ground conditions.
However, a contractor should determine the actual specification for the individual site.
What affects the cost of a small asphalt driveway?
Several factors can change the price substantially.
1. Minimum contractor charges
This matters more on small projects than almost anything else.
The contractor still needs workers, machinery and asphalt delivery regardless of driveway size.
2. Existing surface
Resurfacing existing asphalt costs much less than digging out a front garden.
3. Ground conditions
Soft ground may need deeper foundations and more aggregate.
4. Access
Easy road access allows efficient digger, grab-lorry and asphalt deliveries.
Restricted access can increase labour.
5. Drainage
Adding channels or a soakaway can cost several hundred pounds.
6. Edging
Decorative blocks cost more than basic concrete kerbs.
7. Driveway shape
A simple rectangle is cheaper than curved or tapered areas requiring additional cutting and finishing.
8. Existing landscaping
Walls, hedges and trees may need removal.
9. Dropped kerb
This can add several thousand pounds to a new front driveway.
10. Location
London and the South East generally have higher labour and disposal costs.
Regional small asphalt driveway prices
For a roughly 15 to 20m² driveway:
| UK region | Typical installed cost |
| London | £2,500 to £4,000+ |
| South East England | £2,200 to £3,600 |
| South West England | £2,000 to £3,300 |
| Midlands | £1,900 to £3,100 |
| North of England | £1,800 to £3,000 |
| Wales | £1,800 to £3,000 |
| Scotland | £1,900 to £3,200 |
| Northern Ireland | £1,800 to £3,000 |
These figures exclude a major dropped-kerb project.
How long does a small asphalt driveway take to install?
Most small driveway installations take around two to three days.
Day one
The contractor excavates the site and removes waste.
Day two
They install and compact the sub-base, drainage and edging.
Day two or three
The crew lays and rolls the asphalt.
A resurfacing job may take only one day if the existing base needs little repair.
How soon can I park on new asphalt?
Most contractors advise waiting at least 24 to 48 hours before parking a vehicle on freshly laid asphalt.
During warm summer weather, waiting longer may help prevent marks.
For the first few weeks, avoid:
- turning the steering wheel while stationary
- placing heavy point loads on the surface
- leaving motorcycle stands directly on asphalt
- spilling petrol or solvents
How long should a small asphalt driveway last?
A well-built driveway commonly lasts around 15 to 25 years.
Good installations can last longer.
The lifespan depends heavily on:
- sub-base quality
- drainage
- edge support
- traffic
- tree roots
- ground movement
- maintenance
A cheap surface laid over inadequate foundations may deteriorate far sooner.
Is asphalt good for a one-car driveway?
For many UK homes, yes.
A small asphalt driveway offers several practical advantages:
- relatively affordable
- quick to install
- smooth for parking
- easy to clean
- suitable for slopes
- straightforward to repair
- low routine maintenance
It can also work particularly well where the available front garden is fairly small and a complicated paving pattern would make the area look busy.
Does a small asphalt driveway need planning permission?
In England, size alone does not determine whether permission is needed.
A new or replacement front driveway of any size can generally remain permitted development when it uses a permeable surface or sends runoff into a lawn, flower bed or another permeable area within the property.
For a traditional impermeable driveway covering more than 5m², planning permission may be required if suitable on-site drainage is not provided.
Therefore, even a one-car asphalt driveway will normally exceed the 5m² threshold and needs its drainage arrangement considered carefully.
Different rules may apply elsewhere in the UK or to listed and specially protected properties.
Is a small asphalt driveway suitable for DIY?
A full asphalt installation is not particularly DIY-friendly.
The contractor needs:
- excavation equipment
- compaction equipment
- hot asphalt
- skilled labour
- rollers
- accurate levels
- drainage knowledge
Hot asphalt also has a limited working time.
Therefore, professional installation usually provides a much more consistent result.
How to compare small asphalt driveway quotes
Because minimum costs play such a large role, quotations can vary considerably.
Ask each contractor:
- How deep will you excavate?
- What sub-base will you install?
- How thick will the sub-base be?
- Is a binder course included?
- How thick will the finished surface be?
- Is drainage included?
- Where will rainwater go?
- Is edging included?
- Is waste removal included?
- Will you adjust manholes?
- Does the price include VAT?
- How long should I stay off the driveway?
- What guarantee do you provide?
- Do you carry public liability insurance?
Most importantly, avoid comparing price per square metre alone.
For a small driveway, the construction specification matters much more than achieving the lowest headline rate.

- dropped kerb: £1,500 to £3,500+
- likely total: £3,800 to £7,500+
Is a small asphalt driveway worth the cost?
A one-car asphalt driveway can provide good value where homeowners want a practical parking space without paying for a premium decorative surface.
Although a small installation may have a higher square-metre rate than a larger driveway, the total project cost remains relatively manageable. For many homes, around £2,000 to £3,000 can create a properly constructed one-car parking area.
However, it is worth spending money on the parts you cannot see once the work is complete.
Good excavation, a strong sub-base, effective drainage and solid edging have a much greater influence on lifespan than saving a few hundred pounds on the initial quotation.
FAQs about small asphalt driveway costs
How much does a small one-car asphalt driveway cost in the UK?
A small one-car asphalt driveway typically costs around £1,800 to £3,500. A standard 15 to 20m² driveway will often fall between £2,000 and £3,000, depending on groundwork and drainage.
How much does a 15m² asphalt driveway cost?
A 15m² driveway usually costs around £1,700 to £2,600 for a complete installation.
How much does a 20m² asphalt driveway cost?
A 20m² single-car asphalt driveway typically costs around £2,000 to £3,200. Current UK market averages place a straightforward 20m² installation around the £2,200 mark, although additional groundwork can increase the price.
Why is a small driveway expensive per square metre?
Small projects still involve minimum costs for labour, machinery and hot asphalt delivery. Therefore, the cost per square metre is often higher than on a large driveway.
How much does asphalt resurfacing cost for a small driveway?
Resurfacing an existing sound driveway generally costs around £40 to £70 per m². A 20m² driveway may therefore cost approximately £900 to £1,500.
How much does it cost to turn a small front garden into a driveway?
A complete front garden conversion typically costs around £2,500 to £5,000+, depending on excavation, drainage, landscaping and access.
Does a one-car asphalt driveway need drainage?
Yes. Conventional asphalt is usually impermeable, so the driveway needs somewhere suitable for rainwater to drain.
Do I need planning permission for a small asphalt driveway?
In England, an impermeable front driveway larger than 5m² may require planning permission unless runoff is directed into a permeable area within the property. Permeable or porous asphalt can also provide an alternative.
How much does a dropped kerb cost?
A new dropped kerb commonly costs around £1,500 to £3,500+, depending on local authority requirements and site conditions.
Can asphalt be laid over an existing driveway?
Yes, if the existing surface and foundation remain structurally sound. Resurfacing can reduce the cost significantly compared with full excavation.
How long does a small asphalt driveway take to install?
Most small driveways take around two to three days. Resurfacing may only take one day.
How long should I wait before parking on new asphalt?
Usually, wait at least 24 to 48 hours. In hot weather, the contractor may recommend leaving it longer.
How long does an asphalt driveway last?
A properly built residential asphalt driveway normally lasts around 15 to 25 years, with drainage and foundation quality having a major influence on lifespan.
What should I budget for a one-car asphalt driveway?
For a normal 15 to 20m² driveway, £2,000 to £3,000 provides a useful starting budget. Allow more if the project needs extensive excavation, a soakaway, decorative edging or a new dropped kerb.
For homeowners comparing quotes, the key point is to look beyond the final asphalt layer. A £2,000 installation with properly compacted foundations and suitable drainage may provide far better value than a cheaper surface laid over inadequate groundwork.
