Who this guide is for
Estimators, architects, and trade contractors. Scope: England & Wales.
Approved Document Cost Impact
- Part L (Conservation of Fuel & Power): High-performance insulation (e.g. 100mm Celotex/Kingspan), triple glazing, and low-carbon heating allowances.
- Part B (Fire Safety): Fire-rated plasterboard (15mm Type F), intumescent seals, smoke alarms, and escape windows.
- Part F (Ventilation): Mechanical extract fans, trickle vents, and continuous background ventilation systems.
Miniature Example
Meeting updated Part L thermal targets adds £18/m² in higher-spec insulation materials across 80 m² of cavity wall construction, totaling £1,440 in material cost increases.
