Apologies to everyone: sloppy research on my part - I only went back to early June 2011 when this thread started. jon14 is right, there is earlier information. Most of it put in the public domain by Westminster Council and Westminster’s Cabinet Member for Housing.

It would appear that some of the information came from a report titled City of Westminster, Housing Needs Assessment 2006 (published in 2007).

However Westminster's claim that over 2,200 Council tenant households earn over £50,000 a year has proved to be substantially inaccurate, after figures demanded by elected members were released by the Council’s Chief Executive.

The more accurate figures, from the 2006 Housing Needs Survey, show that only 406 Council tenant households earned more £50,000 a year, with 38% of these ‘wealthy’ households containing 5 wage earners (average wage of less than £10,000 a year), 38% of households containing 2 wage earners (average wage of £25,000 a year) and 23% of those households containing three wage earners (average wage of £17,000 a year).

Westminster Council arrived at this conflated “2,200? figure by adding in over 1,800 Housing Association households to the Council’s figures. The council has no authority or responsibility for these HA households.

The published figures also show that no Westminster Council tenant household earns more than £100,000 a year.

Housing Association tenants who earned an aggregated £100,000 a year, had 89% of those households containing four wage earners (average wage of £25,000 a year).

The Cabinet Member for Housing perpetrated the inaccuracy and stated that estimates deriving from the 2006 Housing Needs Survey, showed that the Council had more than 200 households with incomes greater than £100,000 per annum, and more than 2,000 households with incomes greater than £50,000 per annum.”

These numbers were not sustained by the published evidence and were only created by conflating and adding in estimates of numbers from other letting bodies.
