Block paving a driveway or garden area is one of the most satisfying large-scale DIY projects you can undertake — and one of the most financially rewarding. A professional driveway installation typically costs £3,000–£8,000 depending on size and material; doing it yourself brings that down to £500–£2,000 for materials and tool hire. It's hard physical work that requires careful preparation, but the skills involved are genuinely learnable over a single weekend project. This step-by-step guide covers everything from planning permission to jointing sand.

Before You Start: Planning Permission and Legal Requirements

If you're paving a front driveway in England, planning permission rules changed significantly in 2008. You do not need planning permission for a front garden driveway if:

The area being paved is less than 5 square metres, OR
You use permeable (porous) paving or direct rainwater to a lawn or border for drainage, OR
The driveway is for a property other than a house (flats and listed buildings have different rules)

If you use impermeable paving (standard block paving) on more than 5 square metres of front garden without proper drainage provision, you technically need planning permission — a rule introduced to address urban flood risk from the wholesale paving of front gardens. In practice, many homeowners proceed without permission, but the legal obligation exists. Permeable block paving (see below) neatly sidesteps this issue and is worth considering.

For back gardens and patios, no planning restrictions apply regardless of area or drainage type.

Planning Your Project

Calculating quantities

Measure the area carefully: length × width = square metres. Add 10% for cutting waste. Standard block paving blocks in the UK are 200mm × 100mm × 65mm — this is the most common size, used by Marshalls, Brett Paving and most own-brand products. At this size you'll need approximately 50 blocks per square metre. For a typical double driveway of 40–50m², you're looking at 2,200–2,750 blocks before waste.

Sub-base stone (MOT Type 1 crushed limestone): allow 150mm depth for pedestrian areas, 200mm for driveways. A 150mm sub-base over 45m² requires approximately 10 tonnes of Type 1 — order in bulk from a local builders' merchant; it's delivered by tipper lorry.

Sharp sand for the laying course: 40mm depth over 45m² = approximately 3 tonnes.

Kiln dried jointing sand: approximately 3–5kg per square metre, so 150–225kg for a 45m² driveway.

Choosing your blocks

Marshalls and Brett Paving are the two dominant UK manufacturers. Marshalls Drivesett Argent and Brett Omega are popular mid-range choices that balance appearance with durability. Expect to pay £18–£35 per square metre for quality block paving, or £10–£18 for budget imported blocks. The price difference in blocks is relatively small compared to your labour and sub-base costs — don't compromise quality at this stage.

Colours: blend at least two shades if you want a natural look. Order from the same batch where possible — colour can vary between production runs.

Tools and Equipment

You'll need to hire several pieces of equipment — factor this into your budget alongside materials:

Plate compactor (wacker plate): Essential for compacting the sub-base and for bedding blocks. Hire from HSS or Speedy Hire: approximately £60/day or £150/week. This is the most important piece of equipment.
Block splitter or angle grinder with diamond blade: For cutting blocks to fit edges and curves. Block splitter hire: £30–£50/day. An angle grinder with a 230mm diamond blade works well for curved cuts that a splitter can't handle.
String line and pegs: For setting levels and laying out the pattern.
Screeding rails (2× lengths of 38mm timber or steel square section): For levelling the sand laying course.
Long straight edge (2–3m spirit level or aluminium straight edge)
Rubber mallet
Stiff broom for jointing sand
Pointing bar or bolster chisel
Tape measure, chalk line, pencil

Step 1: Excavation

This is the most physically demanding part of the project. The total excavation depth depends on your finish level and sub-base depth:

Block thickness: 65mm
Sand laying course: 40mm (it will compact to around 30mm)
Sub-base: 150mm (pedestrian/light vehicle) or 200mm (heavy vehicles)
Total excavation for a driveway: approximately 305mm (12 inches) below finished surface level

Mark out the area with string lines set to finished surface height. Use a line level or laser level to set your string lines accurately — slope away from the house at a minimum gradient of 1:60 (17mm fall per metre) for drainage. More is fine; less risks water pooling against the building.

Excavate by hand or hire a mini digger (around £150/day with delivery for a 1-tonne machine — well worth it for large areas). Remove the arisings — topsoil and subsoil — to a skip or arrange for collection. A 10-tonne skip typically handles the spoil from a 30–40m² excavation.

Step 2: Laying and Compacting the Sub-Base

The sub-base is what prevents your paving from sinking or cracking under load. Don't scrimp on depth or quality here — poor sub-base preparation is the leading cause of block paving failure.

Tip MOT Type 1 crusher run into the excavation. Spread to an even depth with a rake — initially aim for 20–25mm over your target depth to allow for compaction.
Run the plate compactor over the sub-base in overlapping passes, working in a grid pattern. Make at least three full passes in different directions.
The stone will compact significantly — Type 1 typically compacts by 15–20%. Add more material and compact again until you reach your target depth with a firm, unyielding surface.
Check your levels with a long straight edge and spirit level. The sub-base surface should mirror your finished surface profile (sloped for drainage).

In clay-heavy soil or areas with known drainage problems, consider laying a geotextile membrane on the base of the excavation before the sub-base goes in. This separates the sub-base from the soil beneath and prevents fine particles migrating upward over time.

Step 3: Edge Restraints

Block paving must be contained by a solid edge restraint on all sides. Without one, blocks migrate outward over time and the paving spreads and becomes unstable.

Options for edge restraints:

Concrete haunching: Lay the first row of blocks around the perimeter, then haunch them in with a concrete mix (1:5 cement:ballast). Allow to cure for 24–48 hours before laying the field blocks. This is the most common professional method.
Kerb stones: Lay full kerb stones or half-batt kerbs on a concrete bed at the perimeter. More formal, but provides a very robust edge — particularly important at the road edge of driveways.
Proprietary plastic edging: Cheaper and faster, but less durable under vehicle load. Acceptable for pedestrian areas and paths.

Step 4: Screeding the Sand Laying Course

With the sub-base compacted and edge restraints set, lay your screeding rails (two parallel lengths of 38mm square timber or steel) across the area approximately 2–3m apart and set to the correct finished height minus the block thickness (65mm below finished level means the top of the rails should be 65mm below your string lines).

Tip sharp sand between the rails in generous quantities.
Run a screed board (a length of timber or straight aluminium section) across the rails, pulling it towards you with a back-and-forth sawing motion to level the sand to the top of the rails.
Remove the rails and fill the channels with sand; re-screed lightly to level.
Do not compact the sand at this stage. Do not walk on it if you can avoid it.
Work in sections across the area so you're always placing blocks from a firm edge, reaching across the screeded sand rather than walking on it.

Step 5: Laying the Blocks

Now the satisfying part. Start from a straight edge — a house wall, a straight kerb line, or a string line — and work outwards.

Laying pattern

The most common patterns for UK driveways:

Herringbone (45° or 90°): The strongest pattern for driveways. Interlocks to resist the horizontal forces of vehicle tyres. 45° herringbone is the professional standard for any surface that will carry vehicles. More complex to lay (more cuts at edges), but significantly better performance.
Running bond: Simple rows offset by half a block. Quick to lay, looks good, but weaker than herringbone under vehicle load.
Basketweave: Pairs of blocks alternating in direction. Attractive for patios; not recommended for driveways.

Laying technique

Place each block gently into position without dragging it across the sand — dragging displaces sand and creates high spots.
Each block should be placed slightly high (by 5–10mm) and tapped down with a rubber mallet or a block placed on top and hit with a regular hammer, so the top surface is roughly level with adjacent blocks.
Maintain consistent joint gaps (2–3mm is standard for block paving) using a template or consistent eye judgment.
Check levels regularly with a long straight edge and spirit level. Correct any high or low blocks immediately by adding or removing sand beneath.
Cut blocks for edges using the block splitter (for straight cuts) or angle grinder (for curves).

Step 6: Compaction and Jointing

Once all blocks are laid and cut to edges:

Run the plate compactor over the entire area in overlapping passes. Place a rubber mat under the plate (or hire a plate with a rubber sole plate) to avoid surface marking. The blocks will drop 10–15mm and the sand will lock them in place.
Spread kiln-dried jointing sand over the surface and sweep it across with a stiff broom, working it into the joints. Apply generously.
Run the plate compactor over again to vibrate the sand into the joints.
Repeat — sweep more jointing sand in, compact again. You may need three or four rounds before the joints are consistently full.
Sweep off any excess sand from the surface.

Common Mistakes

Insufficient sub-base depth: The single biggest cause of block paving failure. On clay soils and for vehicle-bearing surfaces, 200mm of compacted Type 1 is the minimum.
Laying blocks directly on soil: Seen occasionally in garden DIY. Always use a proper sub-base — soil compresses and drains unevenly.
Not setting adequate falls: Paving that is level or falls towards the house creates drainage problems and potential damp issues. Check the fall with a level and tape throughout the job.
Walking on the screeded sand: This creates hollows that are hard to correct. Work from the hard edge, placing blocks from a kneeling board on laid blocks.
Skipping edge restraints: Block paving without edge restraints will migrate and spread within two or three years of vehicle use.
Using building sand instead of sharp sand: Building sand is too fine and compresses unevenly. Always use sharp (grit) sand for the laying course.

Summary

Laying block paving is achievable over a weekend (for small areas) to two or three weekends (for a full driveway) if you plan thoroughly, hire the right equipment and don't cut corners on the sub-base. The work is physical and unforgiving of preparation shortcuts, but the skills are straightforward and the result — a professional-looking, long-lasting surface at a fraction of the cost of a professional installation — is deeply satisfying. Get the excavation depth, sub-base compaction and drainage gradient right, and the rest falls into place.
