Step-by-Step Guide
Assess Your Site and Soil Conditions
Before choosing any material, check whether your ground is stable and well-drained. Clay-heavy soil shifts and heaves, which will crack rigid slabs — on clay you need a deeper sub-base or a more flexible surface like block paving. Probe the ground with a spike after rain; if water pools for more than 30 minutes, factor drainage into your budget before you price a single slab. Poor ground preparation is the leading cause of sunken and cracked patios, so get this stage right first. See our guide on fixing sunken patio slabs to understand what happens when the sub-base fails.
Set Your Budget Per Square Metre
Material costs vary enormously: gravel and basic concrete slabs sit at the lower end (around £20–£35 per m²), mid-range natural sandstone and reconstituted stone run £35–£65 per m², and premium porcelain or granite can reach £80–£120 per m² or more before labour. Calculate your patio area accurately with a tape measure, then multiply by the cost per m² for each material you are considering. If you want to keep costs down without sacrificing the finish, read our guide to laying a patio on a budget for practical cost-cutting strategies.
Compare the Main Material Options
Concrete slabs are cheap, widely available, and easy to replace individually but can look utilitarian and stain readily. Natural stone (sandstone, limestone, slate) looks premium and ages beautifully but needs sealing and varies in thickness, making levelling harder. Porcelain is frost-resistant, low-maintenance, and consistent in thickness — ideal for modern gardens — but it is slippery when wet unless you specify a textured finish, and it requires a solid, level mortar bed. Block paving is highly durable, flexible over ground movement, and drainage-friendly if laid on sand, but joints need regular re-sanding to suppress weeds. Gravel is the cheapest option and drains freely, making it a permeable surface solution, but it migrates underfoot and is not ideal for furniture or elderly or mobility-impaired users. Weigh each against your priorities: budget, aesthetics, maintenance, and safety.
Check Drainage and Planning Rules
Any hard surface over 5 m² in a front garden must be permeable or drain to a lawn or border under permitted development rules in England — laying impermeable paving without planning permission is a common and costly mistake. Rear gardens have more flexibility, but surface water must still be managed on your own property and not discharged to a highway drain. Permeable block paving, gravel, or slabs with open joints over a free-draining sub-base all satisfy this requirement. Check current guidance via the Planning Portal (gov.uk) before you order. Poor drainage also accelerates algae and moss growth, so a 1:80 fall away from the house is the minimum gradient you should build in — and why you will eventually need to clean and pressure wash your patio less often if drainage is correct from the start.
Factor In Long-Term Maintenance
Every patio surface requires some upkeep — the question is how much. Concrete slabs discolour and may need sealing every two to three years. Natural stone needs an impregnating sealer applied before first use and re-applied periodically; unsealed sandstone stains from leaves and iron deposits within a single winter. Porcelain is the lowest-maintenance option but joints still need attention — use a specialist jointing compound rather than standard mortar, which can crack and allow weed ingress. Block paving joints require kiln-dried sand to be brushed in annually and the surface re-sanded after pressure washing. Gravel needs raking and topping up as material migrates. Build maintenance cost and effort into your decision, not just the upfront price.
Order Materials and Plan the Installation Method
Once you have chosen your surface material, confirm the correct installation method before ordering. Porcelain and large-format natural stone require a full mortar bed on a compacted MOT Type 1 sub-base — they cannot be dry-laid on sand alone. Standard concrete and reconstituted slabs can be laid on five mortar dabs over compacted hardcore and sand, but a full bed is stronger. Block paving is bedded on 50 mm of sharp sand over compacted hardcore. Gravel goes over weed-suppressing membrane on compacted hardcore, retained with permanent edging. Order 10–15% extra material to allow for cuts and breakages. For a full step-by-step installation walkthrough, see our guide to laying paving slabs once your material choice is confirmed.
Frequently Asked Questions
Which patio material lasts the longest?
Granite and porcelain are the most durable patio materials in the UK climate — both resist frost, staining, and surface wear for decades with minimal maintenance. Natural sandstone and limestone are also long-lasting but require sealing to prevent surface erosion and staining.
What is the cheapest patio material in the UK?
Gravel is the cheapest option at around £20–£30 per m² including membrane and edging. Basic concrete paving slabs follow at roughly £20–£35 per m². Both are DIY-friendly, but gravel is not suitable where level access or furniture stability is needed.
Do I need planning permission to lay a patio?
In most cases, no — rear garden patios are permitted development. However, any hard surface over 5 m² in a front garden must be permeable or drain to a planted area, otherwise planning permission is required. Always check with your local planning authority if you are unsure.
Is porcelain paving slippery when wet?
Standard polished porcelain can be slippery when wet, making it unsuitable for most outdoor use. Always specify a textured or ‘anti-slip’ rated finish with an R11 slip-resistance rating or higher for any external patio — reputable suppliers will confirm the rating on the product specification sheet.
What patio material is best for a low-maintenance garden?
Porcelain paving is widely regarded as the lowest-maintenance option — it resists staining, moss, and frost without sealing, and cleans easily with a pressure washer. Cleaning and pressure washing once or twice a year is usually all that is needed to keep porcelain looking new.
When laying natural stone or porcelain, always seal the edges of cut slabs with the same impregnating sealer you use on the face — cut edges are raw and far more porous than the finished surface, and they will absorb water, stain, and deteriorate faster than the rest of the slab if left untreated.
