How many blocks, bricks or slabs do I need per square metre?

Standard UK coverage rates: about 10 concrete blocks per m² (440x215mm), about 60 bricks per m² in a half-brick wall, and about 2.78 slabs per m² for 600x600mm paving. Always add a wastage factor — 5 to 10 percent is typical for cuts and breakages.

How much do UK trades lose by underpricing jobs?

Surveyed UK trades lose around £3,200 a year on average to poor job pricing and underquoting (FSB, 2024). Tradespeople using materials-quantity-based pricing commonly find they had been underquoting by 15 to 25 percent.

How it works

GUT FEEL IS EXPENSIVE

Most trades quote from instinct — and the average UK trade loses around £3,200 a year to underquoting (FSB, 2024). The Job Pricer replaces the guesswork: enter the job's dimensions, and it calculates exact material quantities using industry-standard coverage rates across 54+ materials, applies your configurable wastage factor, adds labour at your day rate, then your margin and VAT on top.

You enter your actual unit costs, so the totals are exact — what you put in is what you get out. Tradespeople pricing this way consistently find they'd been underquoting by 15–25%. One tap sends the finished price to a branded quote or invoice.

The Job Pricer is on the Growth and Enterprise plans, alongside the Subbies Hub and RAMS Generator. Doing CIS sums in the meantime? Our free CIS deduction calculator is open to everyone.
