Spon’s Architects’ and Builders’ Price Book 2026

Compiled by AECOM, the 2026 edition has been updated with the latest pricing information to help you manage your projects over the next 12 months through this challenging period of inflationary pressure, global uncertainty and skills shortages.

It includes 20,000 prices for the most frequently specified construction items, the majority with labour constants and detailed build-ups. All prices have been updated via comprehensive supplier engagement combined with AECOM’s market intelligence and a short-term inflationary forecast to ensure you have the most accurate cost data available. Activity descriptions and build ups have been updated to reflect changes to standard specifications, Building Regulation changes, emerging practices, and changing outputs. Although it suits a wide range of project sizes, this is the only price book which sets out a detailed cost base for contracts exceeding 4,000,000 in value.

All the standard features you have come to expect from SPON’S ARCHITECTS’ AND BUILDERS’ PRICE BOOK are also included:

• Hundreds of alternative materials prices for the more unusual items
• Detailed guidance on wage rates, daywork, cost limits and allowances, property insurance and professional fees, plus useful formulae, design criteria and trade association addresses

Included within the inside front cover of every book is a VitalSource(R) eBook redemption code giving one user access to the content digitally until the end of December 2026.

AECOM is one of the world’s largest infrastructure design firms.
