It is not possible at this time to provide the costings requested as there are a range of complex considerations and scenarios, as well as local circumstances, to take into account when calculating such a figure.
My Department has been examining the existing income limits in the context of current market and household income conditions, including the suitability or otherwise of the current framework having regard to the significantly changed landscape since the standardised income limits were introduced. This includes examining the findings of research commissioned by my Department and this work is ongoing.
I expect that the analysis will be concluded shortly to facilitate a final determination on next steps. I am also keen to put in place a more structured and frequent process for the review of these limits going forward.
