Joseph Rowntree Foundation report on claimant's experiences of UC conditionality and sanctions here.
National Audit Office call for DWP to conduct a wide-ranging review here
. The NAO points out inconsistencies - "...some Work Programme providers referring twice as many people for sanctions as other providers in the same area
" and inefficiencies /waste of public resources - the DWP estimates it spends £30-50 million a year applying sanctions, plus £200 million monitoring the conditions it sets for claimants; the NAO estimates £132 million in sanctions reductions but paid Hardship Payments of £35 million.
