Information on Non-consolidated performance related pay for HM Treasury is publically available on gov.uk as part of the Transparency agenda. The information is up to date for the last 2 financial years 2012-13 and 2013-14.
Non-consolidated performance related pay is only paid to reward excellence, for example to recognise and incentivise those responsible for delivering high quality public services and savings to the taxpayer. These one-off payments are not pensionable. Since 2010-11 the Government has restricted awards for senior civil servants to the top 25% of performers (from 65% in previous years), saving around £15 million overall.
