Davis Langdon’s cost indices track movements in the input costs of construction work, incorporating national wage agreements and changes in materials prices as measured by government statistics.

They provide an underlying indication of price changes and differential movements in work sectors but do not reflect changes in market conditions affecting profit and overheads, site wage rates, bonuses or any discounts or premiums in materials prices.

Market conditions are recorded in Davis Langdon’s quarterly Market Forecast (last published in Building on 25 July).
