How much does a tarmac driveway cost in Worcestershire?
Tarmac is the best-value durable hard-surface driveway tier in Worcestershire. It cleanly undercuts block paving and resin per area while still offering a clean, contemporary finish.
What's included in the per-square-metre price: excavation, geotextile membrane, 100–150mm compacted Type 1 MOT sub-base, 50–60mm binder asphalt base course, 25–30mm 6mm dense wearing surface course, basic concrete edge restraint, falls set at 1:80 away from the property. What's quoted separately and varies by project: dropped kerb installation, drainage works (ACO channels, soakaways), premium edging (granite setts, block paving borders), traffic management for narrow-access sites.
Why prices vary within the band: depth of excavation needed (more = more cost), whether the existing base can be overlaid (cheaper) or needs full rebuild (more expensive), edging choice, access for trucks. A driveway with full skip and tipper access on a residential road is significantly cheaper than the same driveway down a narrow lane.

What's the difference between tarmac and asphalt?
In everyday UK usage the two terms are interchangeable – both mean the black hard-wearing road and driveway surface made from aggregate and a black binder. Strictly though, they refer to different products:
Tarmac (tarmacadam) is the original product, patented in 1902 by Edgar Hooley. It uses tar – a by-product of coal gas production – as the binder for the stone aggregate. Tar was widely available throughout the 20th century from gasworks.
Asphalt uses bitumen (a refined petroleum product) as the binder instead of tar. Bitumen is more stable, more weather-resistant and easier to work with than tar. From the 1980s onwards, as gasworks closed and bitumen became universally available, the UK industry switched almost entirely to bitumen-bound asphalt.
So when someone in Worcestershire orders a "tarmac driveway" in 2026, what they actually get is bitumen-bound asphalt. The look, feel, install method and performance are essentially identical to traditional tarmacadam, which is why the names are used interchangeably. The branding stuck even though the product evolved.
Are there meaningful differences worth caring about? Not really – bitumen asphalt outperforms old-style tar tarmac on every metric (durability, weather resistance, environmental profile). When someone offers genuine traditional tarmacadam today it's almost always a marketing flourish. See our full guide on the tarmac driveways page.
How long does a tarmac driveway last?
A properly installed tarmac driveway lasts 15 to 20 years with minimal maintenance. With periodic re-sealing every 3 to 5 years that lifespan can extend to 25 years.
Lifespan depends on three factors:
1. Sub-base quality. 100–150mm of properly compacted Type 1 MOT sub-base on geotextile membrane is the single biggest determinant of how long the surface lasts. Skimped sub-bases lead to sinking, ripples and cracks within years.
2. Binder content and lay temperature. Tarmac laid too cold or with insufficient bitumen content doesn't bond properly and cracks early. Quality contractors lay at 140°C+ and roll while the material is still plastic.
3. Edge restraint. Without a proper concrete or block edge, tarmac ravels at the perimeter, lets water under, and starts to lift. Every Cathedral Landscapes tarmac driveway has a proper edge detail.
Sealing every 3–5 years adds significant life by replacing the bitumen lost to UV oxidisation and filling micro-cracks before they grow. The cost of sealing is small compared to relaying. See our driveway sealing service for re-seal options.
Can tarmac be laid over an existing driveway?
Yes, in many cases – a fresh tarmac surface course can be laid over an existing tarmac or concrete base. This is called an "overlay" and is significantly cheaper than a full rebuild because you save on excavation, sub-base, spoil disposal and most of the edging work.
Overlay works when:
• The existing base is structurally sound (no major cracks, no sinking patches, no oil contamination)
• Levels and falls are acceptable (or can be corrected with the overlay layer thickness)
• There's enough kerb height available to take the additional 25–40mm overlay without creating a step at the door or gate
• The existing surface can be cleaned and primed (a tack coat) so the new layer bonds properly
Overlay doesn't work when the existing base is failing structurally. Patched sub-base, deep cracking, sunken sections – a fresh top layer just follows the underlying contours and the problems telegraph through within months. In these cases full excavation and rebuild is the only honest solution.
We carry out a free site survey to give a definitive answer. Where it's a close call we'll quote both options – overlay vs full rebuild – so you can make an informed decision.
Do I need planning permission for tarmac?
Standard impermeable tarmac driveways over 5 square metres in front of a property need either planning permission OR alternative drainage to comply with the 2008 SUDS rules. There are three workarounds:
1. Porous tarmac – specialist tarmac that allows water to drain through it into a permeable sub-base. SUDS compliant, no planning needed. Costs more than standard tarmac and only justifies itself when full permeability is genuinely needed.
2. Drainage to a soakaway or planted area – surface water from the tarmac runs into a French drain, ACO channel or planted bed that soaks the water into the ground on your property. The standard solution for most tarmac driveways on tight sites.
3. Planning permission – submit an application to the local planning authority. The slowest and most expensive route; usually only chosen where the site genuinely can't accommodate option 1 or 2.
For most Worcestershire tarmac driveways we design option 2 as standard – a discreet drainage channel along the front or a permeable edge strip catches all runoff. Rear and side driveways are not covered by the SUDS rule so plain tarmac is fine.
If full permeability is your hard priority, you might be better looking at resin bound or gravel – both permeable by default with no extra drainage works needed.
Why is my tarmac driveway turning grey?
Fresh tarmac is rich black because the bitumen binder coats every piece of aggregate at the surface. Over 3 to 5 years, two things happen:
1. UV light oxidises the surface bitumen. Sunlight breaks down the bitumen molecules, releasing volatile compounds and leaving the surface progressively lighter, drier and more porous.
2. Surface aggregate becomes more visible. As the binder oxidises, the underlying stone aggregate – usually grey limestone or granite – becomes more visible at the surface. This grey colour was always there beneath; it's just been exposed.
The result is a driveway that's structurally fine but cosmetically tired. It's not damage and the tarmac hasn't "gone bad" – it's a predictable natural process. Re-sealing replaces the lost bitumen at the surface, restores the original rich black colour, fills micro-cracks before they grow into structural ones, and adds a wear layer that resists fuel spills.
Sealing should be done every 3 to 5 years. The first re-seal at year 3 is the most visually dramatic – you'll have a near-new looking driveway again. Subsequent re-seals at 6, 9, 12 years extend the life and look indefinitely. See our driveway sealing service.
Should I seal my tarmac driveway?
Yes, every 3 to 5 years. Sealing a tarmac driveway delivers four benefits:
1. Colour restoration. The sealer replaces the bitumen at the surface that has oxidised in UV light, restoring the rich black colour to near-new appearance.
2. Crack prevention. Micro-cracks invisible to the eye are filled by the seal coat before they grow into structural cracks that admit water into the sub-base.
3. Stain resistance. The seal layer resists fuel spills, oil drips and surface staining, making routine cleaning easier.
4. Lifespan extension. A driveway sealed regularly typically lasts 25+ years vs 15–20 years unsealed.
The economics: a re-seal costs a fraction of a re-lay, and you get 5 years of restored look from each treatment. Over a 25-year driveway life that's typically 4–5 re-seals at modest cost vs one expensive rebuild.
Timing: leave new tarmac for at least 6 months before the first seal – the bitumen needs to cure naturally before adding a sealer. After that, plan a re-seal every 3–5 years depending on traffic and exposure. Heavily-shaded driveways with high moisture exposure benefit from more frequent sealing.
What to avoid: cheap DIY "coal tar emulsion" products. They look black for a few months then crack and flake. Quality acrylic tarmac sealer (what we apply professionally) bonds chemically and lasts.
How long does a tarmac driveway take to install?
A typical residential tarmac driveway is installed in 1 to 2 days, broken into clear stages:
Day 1 – Excavate to depth, lay geotextile membrane, place and compact 100–150mm Type 1 MOT sub-base in two layers. Set concrete-bedded edging or kerb to designed levels and falls. Lay the 50–60mm binder asphalt base course while hot, roll to compaction. By end of day 1 you have a usable, weatherable base course in place.
Day 2 – Apply a tack coat to bond the surface course to the base. Lay the 25–30mm 6mm dense wearing surface course while hot (140°C+), roll to compaction. Hand-finish edges and joins around manholes, drains and entrances. Tidy site, sweep paths.
Same day finish – You can walk on tarmac within a few hours of laying. Drive on it after 24 to 48 hours (sooner in hot weather as it cures faster, longer in cool weather).
What can extend timing? Removing an existing driveway (+1–2 days), drainage works (+1 day), dropped kerb install (separate scheduled job, 1–2 days), bad weather (we don't lay in rain or under 5°C), unexpected ground conditions (rock, made ground, buried obstacles). We allow for all of this in the quoted timeline and keep you updated daily.
For driveways being completed alongside a dropped kerb, we usually sequence both jobs together – dropped kerb installed first then driveway tarmac laid up to it for a continuous, clean finish.
