Tarmac vs Block Paving Driveways in Enfield: Costs & Benefits

Most Enfield homeowners planning a new driveway end up with the same two options on the shortlist. Tarmac wins on price and speed. Block paving wins on looks and repairs. Both last decades if the groundwork is done properly, and both fail early if it is not. This guide sets out how they compare on cost, durability, upkeep and appearance, so you can decide before the autumn weather makes the job harder to schedule.

What a Tarmac Driveway Offers

Tarmac is a single continuous surface, laid hot and rolled flat while it is still workable.

Bitumen binder and graded stone arrive on site at roughly 140°C to 160°C, get spread and then compacted with a roller before they cool. That gives you one unbroken sheet across the whole driveway with nowhere for weeds to push through.

The practical appeal:

• Lowest cost per square metre of the common driveway surfaces
• Fast to lay, often finished in a day or two once groundworks are done
• Smooth and quiet underfoot, easy for bikes, prams and wheelchairs
• Handles heavy vehicles well when the base is built correctly
• Simple to sweep and keep clear

The trade-off is character. Tarmac is black, then slightly greyer black. Colour options exist but the choice is narrow.

What Block Paving Offers

Block paving is the opposite approach: hundreds of individual units laid on sand over a compacted base, locked together by friction and edge restraints.

Think chain mail against a sheet of plate armour. The sheet is seamless and strong, though a dent stays a dent. Chain mail flexes with movement, and a damaged link comes out and gets replaced. Block paving works the same way.

What you get:

• Wide choice of colours, shapes, patterns and border details
• Individual blocks can be lifted and relaid after a repair
• Permeable ranges available, which helps with drainage rules
• Patterns like herringbone that spread vehicle loads across neighbouring blocks
• Strong kerb appeal, particularly on period and Victorian properties around Enfield

Cost Comparison

Price is usually the first question and rarely the whole answer.

As a rough guide for a domestic driveway in the Enfield area, including excavation and a proper sub-base:

1. Tarmac: the lower end of the scale, typically around a third less per square metre than block paving
2. Block paving: noticeably higher, driven by the cost of the blocks themselves and the labour to lay, cut and compact them
3. Both: identical spend on excavation, sub-base, edgings and spoil removal

Labour explains most of the gap. A tarmac crew covers a driveway in hours. Block paving is laid piece by piece, with every cut around a manhole, gatepost or curve done by hand.

Access matters too. Narrow side returns and long carries push both prices up. Get itemised quotes so you can see what belongs to the surface and what belongs to the groundwork underneath.

Durability and Lifespan

Both surfaces last well. They fail in different ways.

A well-built tarmac driveway runs 15 to 20 years. It softens in prolonged heat, so a car parked with the wheels turned can leave scuff marks in high summer, and jack stands or motorbike stands can press in. Petrol and diesel drips soften bitumen over time, which is worth knowing if you service your own car.

Block paving lasts 20 to 25 years or more. Its weak points are movement and joints. Poor edge restraints let blocks spread outwards, and sand washing from the joints allows weeds and moss. Neither problem is expensive to fix if caught early.

Sub-base depth decides both outcomes. Skimp underneath and the surface fails whichever one you chose.

Weight makes a difference as well. If you park a van, a caravan or two family cars nose to tail, say so at quoting stage. The answer is usually a deeper sub-base rather than a different surface, and it costs far less to build in at the start than to rebuild later.

Repairs and Maintenance

This is where the two diverge most sharply over twenty years.

Tarmac upkeep:

• Sweep occasionally and clear leaves before they stain
• Reseal every few years to keep the colour and protect the binder
• Repairs mean cutting out a section and patching, and patches rarely match the surrounding colour
• Oil spills should be cleaned quickly

Block paving upkeep:

• Brush and pressure wash annually on a low setting
• Top up kiln-dried sand in the joints afterwards
• Treat weeds as they appear, or choose a polymeric jointing sand
• Replace damaged or stained blocks individually, keeping spares from the original pallet

If a water company or cable provider ever digs up your frontage, block paving goes back down almost invisibly. Tarmac does not.

Kerb Appeal and Resale

Enfield housing stock ranges from Victorian terraces in Bush Hill Park to interwar semis and newer estates, and the right surface follows the house.

Block paving suits period frontages, especially with a contrasting border picking up the brickwork. Buyers notice it. Estate agents mention it.

Tarmac reads as neat and practical rather than decorative, which suits plenty of houses perfectly well. A block paved border around a tarmac centre is a popular middle ground in the area, giving definition at the edges at a fraction of the cost of a fully paved drive.

For longer driveways, the maths favours tarmac. On a short frontage where the whole surface is visible from the pavement, block paving usually earns its extra cost.

Drainage and Enfield Planning Rules

A few local points catch people out, and they apply whichever surface you pick.

Since 2008, covering more than five square metres of front garden with an impermeable surface in England needs planning permission, unless rainwater drains to a permeable area or soakaway inside your own boundary. Standard tarmac is impermeable. Standard block paving is too, though permeable block ranges solve it neatly.

The London Borough of Enfield handles both planning and highways locally, so a dropped kerb application goes to the council directly rather than a separate county authority. Enfield also has several conservation areas where surface materials can be restricted, so check before ordering anything.

Whichever you choose, the driveway needs falls that send water into a channel drain or soakaway rather than back to your house or the public footway.

Which Surface Suits Your Home?

A short way to decide.

Choose tarmac if:

• Budget matters most
• The driveway is long, wide or awkwardly shaped
• You want the job finished quickly
• Practicality outranks appearance

Choose block paving if:

• The frontage is short and fully on show
• Your house is period or traditional
• You want colour, pattern and defined edges
• Future dig-ups or repairs concern you
