Key findings include –

savings to the DWP have been less than estimated – approximately £330 million in the first year, £115 million less than the original target;

only around 6 per cent of tenants moved as a result of the bedroom tax in the first six months;

by November 2013, 22 per cent of those still affected (up to 100,000 tenants) remained registered for transfer or exchange – a shortage of smaller homes prevents households moving particularly in Wales and the north of England;

in areas where more tenants have moved, such as London, this has increased availability of larger homes for homeless or overcrowded families but reduced availability for smaller homes for new applicants;

almost half of all tenants affected by the bedroom tax are in rent arrears;

discretionary housing payments (DHPs) are not the most approriate way to support households where there is a long-term disability – the report highlights that local authorities differ in practice in how they assess income, in particular whether they take disability living allowance (DLA) into account;

DWP regulations do not define minimum size requirements for a room according to whether it is for single or shared use;

landlords have incurred extra costs through rent arrears, welfare suport, rent collection, arrears management and repairs linked to more transfers.
