Andy is correct.
Clause 29 of the bill does say that they intend to make the end of an EP a change of circs rather than requiring a new claim.
This is from the explanatory notes
[quote:0f6268f77f]Clause 29: Housing and Council Tax Benefit for persons taking up employment; Clause 30: supplemental and; Clause 31: interpretation
164. Under the current scheme, a claimant’s housing benefit or council tax benefit award is ended when they move off the qualifying benefit and meet the other criteria to enable payment of the extended payment. A fresh claim must be made in order to obtain any in work entitlement to housing benefit and council tax benefit.
165. These clauses provide for a simpler method of making extended payments and remove the need for those who receive extended payments to submit a fresh claim for any in-work housing benefit or council tax benefit. If a person stays in their original local authority for the extended payment period, then the amount of the extended payment would be the higher of the out of work housing benefit or council tax benefit they were getting or their in work entitlement to housing benefit or council tax benefit. The extended payment would be paid by the original authority, i.e. the authority that the person was living in just before they took up work. So the move to employment (and entitlement to an extended payment) would be treated like a change of circumstances in a continuing award.[/quote:0f6268f77f]
