Grounded in stated specification: 150mm ground excavation, 100mm compacted MOT Type 1 sub-base, full wet mortar bed with SBR priming slurry, 20mm outdoor vitrified porcelain or calibrated Indian sandstone, resin jointing, and licensed 6-yard skip hire.
How to price person-hours, account for wet mortar bulking, cover £320+ skip costs for excavated spoil, specify sub-base depth, and protect your 20%+ target margin without losing jobs.
Understand what a durable patio truly costs to install, why quotes vary between sandstone and porcelain, and why "spot bedding" quotes fail within two British winters.
Patio Pricing by Area: UK Cost Benchmarks
Patios are rarely priced purely on materials. Fixed mobilization costs (delivery fees, skip hire, plant hire like wacker plates and cement mixers) mean smaller patios have a significantly higher cost per square metre than large terraces:
| Area | Indian Sandstone | Vitrified Porcelain | Duration (2 Crew) |
|---|---|---|---|
| 15m² (Small terrace) | £2,100 – £3,000 | £2,600 – £3,700 | 2 – 3 days |
| 30m² (Standard dining patio) | £4,200 – £5,500 | £4,900 – £6,800 | 4 – 5 days |
| 50m² (Large entertaining patio) | £6,500 – £8,600 | £7,800 – £11,200 | 6 – 8 days |
| 80m² (Wraparound garden patio) | £10,200 – £13,500 | £12,400 – £17,500 | 9 – 12 days |

The 4 Factors That Change a Patio Quote Fast
- Excavation & Soil Disposal: A 30m² patio dug out 150mm produces approximately 4.5 cubic metres of spoil. Soil expands by 30% when dug up (the bulking factor). If there is no wheelbarrow ramp access or you have steps, labour doubles.
- Sub-Base Integrity: Laying directly on earth or building sand is guaranteed failure. A proper patio requires minimum 100mm compacted MOT Type 1 aggregate. Skipping this causes sinking, wobbling, and cracked grout within 12 months.
- Spot Bedding ('Dot and Dab') vs Full Wet Bed: Never accept spot bedding. Slabs must be laid on a continuous, solid mortar bed. Spot bedding creates voids beneath slabs where rainwater collects, freezes, expands, and snaps slabs.
- Drainage & Falls: A patio must fall 1:60 away from the property and sit at least 150mm (two brick courses) below the indoor damp-proof course (DPC), or have a dedicated linear Aco drain installed.
