Cost assumptions disclaimer: Cost assumptions are indicative benchmark estimates normalised to £/m² GIA. They are based on publicly available UK construction cost references and supplier pricing where available. Final project costs will vary by specification, wall height, openings, location, labour rates, delivery, installation method, fire/acoustic requirements, preliminaries and contractor margin. These figures should not be treated as fixed quotations.
Insulation Performance (R-Value / U-Value)
Higher R-value = better insulation. Lower U-value = less heat escaping. UK climate runs ~2,200 heating degree-days annually.
