Head office overheads meaning

In practice, head office overheads are the contractor’s indirect, business-wide costs that are not incurred solely because of a particular project. They are general administrative expenses, typically including rent, business rates, directors’ salaries, finance charges, auditors’ fees, insurance, HR, IT and corporate governance functions. The term is a descriptive accounting/contractual expression rather than one defined by legislation, though specific construction contracts or pricing documents may prescribe how such overheads are recovered. Usage and treatment are broadly consistent across England & Wales, Scotland, Northern Ireland and Ireland. Legally and commercially, head office overheads: - Are distinct from direct costs and from project-specific “site overheads” (preliminaries). - Are commonly recovered through tendered rates/percentages for “overheads and profit”, preliminaries, or the contract “fee” (for example, under NEC forms), subject to the agreed terms. - May be claimed in valuing variations, dayworks, termination, and loss and expense/prolongation claims, where causation and quantum are proved and double recovery is avoided. - Are often assessed using recognised methods (such as turnover-based formulae used in UK construction case law), applied with evidential support (management accounts, cost allocation policies, historic turnover/margin). Their practical significance lies in pricing, valuation, and quantum of claims, ensuring the contractor’s central business costs are fairly apportioned across projects.
