Rates are UK national (non-London): central London and constrained urban sites typically run dearer — adjust the labour, plant and access lines in the build-up accordingly.
215mm solid dense 7.3N blockwork
per m² · supply & lay
£151 – £256 / m²
What is it
The supply and laying of a single skin of 215 mm SOLID dense aggregate blockwork of 7.3 N/mm² grade to a vertical wall, priced per m² of wall face. At 215 mm the solid dense block is the thickest, heaviest unit in the range — a full solid block (a two-man lift) for heavily-loaded and acoustic separating walls where mass and strength matter most. One finish is priced:
Standard — a common-face block, to be plastered, rendered, painted or dry-lined; the usual choice and the default rate.
Rate range by wall complexity

3 key cost drivers
Wall complexity
Openings, returns, piers and reveals slow the gang and add cutting waste. It is a key driver of the rate.
Wall thickness
This rate is for a 215 mm SOLID dense block. A thick solid block is a much dearer, heavier unit (a two-man lift), beds in far more mortar and is laid markedly slower than a thinner or hollow block. Thickness is a key driver of both material cost and laying speed.
Location
London and the South East typically add around 20% to labour.
