Stephen Duckworth has retired as project director at the National Housing Federation.
The federation's expert on stock transfer and pensions, he will continue to advise the NHF on finance. He remains a member of a single regeneration budget partnership board in North Kensington, west London, and will continue working on pensions and European housing as a consultant. He also sits on the board of Ducane and Methodist Homes housing associations.

Duckworth's career at the NHF spanned 20 years. A chartered accountant, he joined the NHF in 1982 after nine years as finance director for Paddington Churches Housing Association. He was the NHF's lead on financial policy issues until 2001 when he concentrated on stock transfer issues.

He was also a member of the Accounting Standards Board's Public Sector and Not for Profit Committee.

Duckworth, 63, was partly responsible for the creation of housing association grant, hostel deficit grant and revenue deficit grant after 1974, and the use of private finance by housing associations.

His staff will take over stock transfer under NHF deputy chief executive James Tickell.

NHF chief executive Jim Coulter said: "Stephen has made a huge contribution to a very wide range of federation work. He has been a vital contributor to our many successes."
