The last time the Government updated its assessment of what different councils in England need to spend was in 2013.
Since 2016, the cuts the Government has been making to the grants it gives to councils have taken into account the council tax revenues they raised in 2015/16. This has left things in need of reform – we cannot end up with a local government finance system where funding in the 2020s and 2030s simply depends on the distribution of grants and council tax revenues in the mid-2010s.
