A new patio is one of the most useful things you can add to a garden, but quotes can vary a lot and it isn't always clear why. This guide covers typical price ranges for patios in and around Liskeard, the groundwork that drives most of the cost, and how to compare quotes properly.
For a professionally laid patio including dig-out, sub-base, bedding and pointing, most homeowners can expect roughly £90 to £150 per square metre for Indian sandstone and £110 to £180 per square metre for porcelain. A straightforward 20 square metre patio on level, easy-access ground often lands somewhere between £2,000 and £3,500. These are guide figures, not fixed prices.
Small patios usually cost more per square metre, because setting up, skip hire and getting a digger on site cost about the same whatever the size. Larger areas spread those fixed costs out. Steps, retaining walls, raised edges and built-in features such as planters or an outdoor kitchen are priced on top.
Ground conditions matter more than anything else, and this is where gardens around Liskeard often differ from the flat plots you see in national price guides. The town and nearby villages sit on hilly ground, so plenty of gardens slope, sometimes steeply. Ground can also change within one garden, with heavy clay in one corner and stony or made-up ground in another. A sloping garden may need cutting in, a retaining wall or a couple of steps before any paving goes down, and soft ground may need a deeper sub-base.
On new-build plots the topsoil is often thin and sits on compacted builders' fill, which needs checking before anyone lays on it. Other things that affect the cost:
Indian sandstone is still popular because it looks natural and suits Cornish stone cottages and older properties. It costs less to buy, but it needs sealing or the odd clean to keep algae down, which matters in a damp, mild climate.
Porcelain is denser, stays cleaner and keeps its colour, so it suits modern extensions and new builds. It costs more and needs a priming slurry and specialist cutting, so labour is higher. Both last well if the base under them is right, and the base is where corners get cut on cheaper quotes.
A good patio falls gently away from the house, usually around 1 in 60 to 1 in 80, so rainwater runs off rather than pooling against walls. It should sit at least 150mm below the damp-proof course. On sloping Liskeard gardens getting these levels right sometimes means stepping the patio or adding a low wall, which is better planned at the start than fixed later.
Underneath, expect a dug-out area of around 150mm to 200mm, a compacted MOT Type 1 sub-base and a full mortar bed. If water has nowhere to go, a soakaway or connection to existing surface drainage may be needed. Paving a front garden over 5 square metres with an impermeable surface that drains onto the road usually needs planning permission, so check with Cornwall Council if it's a front patio.
Ask for a written quote that sets out dig-out depth, sub-base, bedding, material, drainage and waste removal. If two quotes are far apart, it's usually because one leaves out groundwork or drainage. A proper site visit is the only way to price sloping or awkward ground accurately.
R A Groundworks & Utilities is a family-run firm based in Treviscoe, St Austell, working across Cornwall and most of Devon. Director Robert Astin quotes each job and works on site himself, and the firm does not subcontract, so what's agreed at the visit is what gets built.
A typical 20 to 30 square metre patio on easy ground usually takes three to six working days. Sloping sites, retaining walls or extra drainage add time, and very wet weather can cause delays.
Most back garden patios don't need planning permission. Raised patios or decking more than 300mm above ground level, and listed buildings or conservation areas, may be different, so check with Cornwall Council if any of these apply.
Yes, but the slope usually has to be dealt with first by cutting in, building a retaining wall or stepping the patio across levels. This adds to the cost, so it's worth having the ground looked at before setting a budget.
