House Price Data Since 2005

Annual % Change in Average House Prices

Acadata Ltd is an independent research-based consultancy, focused on the UK housing market. Dr Stephen Satchell, Economics Fellow, Trinity College, Cambridge has provided oversight of  our work for some 23 years.

Our link with top-flight academic input was the foundation-stone for the business, and continuing investment in research remains the fundamental characteristic of Acadata’s practice.

Acadata concentrates on house price indices and data- and the way that these can best be researched, analysed and published for our clients- and our partner MIAC Acadametrics handles risk work.

“Our link with top flight academic input was the foundation stone for our business and our continuing investment in research remains the fundamental attribute of our practice.”

Who We Work With

We work with organisations such as The Bank of England, Treasury, major institutions, investment funds, builders, property agents and more. Also with companies big and small for whom a detailed, accurate and completely independent picture of the what is happening in the UK property market is important, thus assisting the making of better fact-based decisions.

An overview of the major HPIs:

For the first view of the “average price paid for houses”: Rightmove’s asking prices indicate sellers’ mood- but very early release means some current data lost. e.surv Acadata “forecast” provides detailed commentary, price trends  and the first published transaction estimates.

For the “price of the average house”: Nationwide for first signals- but early release misses some current data; plus long historic data series. Halifax for complete month data and long historic mortgage valuation data series

For later but largely accurate views of the “average price paid for houses”: ONS has the biggest mortgage data sample and a hedonic regression methodology providing property and buyer characteristic data, but lacks cash sales. e.surv Acadata “final” is close to “ultimate” for use by economists, market research & property management
