Typical costs for the preparation and laying work such as digging out the required area, laying the base and compacting it before laying the patio slabs in sand and pointing between them could cost around Â£30-Â£40 per square metre for labour and materials (not including the patio slabs).lthough they may look durable, if the patio is going to see a lot of use it may be better to stick with a thicker slab. Mid-range patio slabs cost between Â£20 and Â£26 per square metre while top of the range exotic flagstones can cost around Â£32 per square metre.
