This annual compilation of statistical data relies on substantial help and guidance from civil servants at the Ministry of Housing, Communities and Local Government, the Department for Work and Pensions, the Treasury, the Welsh Government, the Scottish Government, the Northern Ireland Executive, the Office for National Statistics and elsewhere. Assistance was also provided by UK Finance, Homes England, the Greater London Authority, the Regulator of Social Housing and the Northern Ireland Housing Executive. Their enormous help in compiling this year's Review is most readily and warmly acknowledged. The Review now also features comparative international statistics kindly provided by Eurostat and the European Mortgage Federation.

We are particularly grateful for the collective help from this year's sponsors, without whom the 29th edition (and future editions) would not be published, especially since the Ministry of Housing, Communities and Local Government is no longer able to make a financial contribution (although it keenly provides 'support in kind'). It is particularly pleasing that among the sponsors are the Scottish Government, Welsh Government and the Northern Ireland Housing Executive.

The University of Glasgow has formal editorial responsibility for the Review, led in this by Professor Mark Stephens. The Review is published by the Chartered Institute of Housing with John Perry as production editor. Jeremy Spencer (graphic designer) is thanked for his tireless patience and creative contribution to its design and production.

For all the diverse help provided, and despite every attempt that has been made to check the figures included in the Review and the construction put upon them, the final responsibility for any errors, omissions or misjudgements is entirely that of the authors. The views expressed in the Review are also the responsibility of the respective authors.
