Scottish Social Housing Tender Price Index

Introduction

The Scottish Social Housing Tender Price Index measures the movement in construction costs of social housing in Scotland. The index is based on analysing the construction costs in accepted tenders for affordable housing. The results are published and dated according to the last month of the calendar quarter represented.

A Scottish Social Housing Tender Price Index description paper is available.

SSHTPI calculation

The Scottish Social Housing Tender Price index is based on comparing the prices for the construction of houses in current schemes with cost models of dwellings of different type (terraced, semi-detached and detached houses and flats in different block configurations); occupancy (numbers of bedrooms and occupants), and size (floor area). These are adjusted for specification and design differences to provide a project tender price index. The project indices are adjusted for location and size of project. The quarterly index is calculated by averaging the adjusted project indices in each quarter. The index is smoothed to take account of the variation in the sample sizes. A full description of the index is available.

The index offers a guide to the movement in prices in social housing schemes in Scotland and is used by the Scottish Government More Homes Division to Division to update the Housing Tender Return, indicative cost calculation.
