A CSV file providing data on all vacant homes of all tenures, 2004 to 2017, for England and out eight local districts, as reported in MHCLG table 615. The data comes from the council tax base statistical release.

Data for council tax base purposes are not taken on the same date every year and can vary slightly from year to year.  The dates to which the figures relate for each year are: 01 Nov 2004, 10 Oct 2004, 09 Oct 2006, 08 Oct 2007, 06 Oct 2008, 05 Oct 2009, 04 Oct 2010, 03 Oct 2011, 01 Oct 2012, 07 Oct 2013, 06 Oct 2014, 05 Oct 2015, 03 Oct 2016, 02 Oct 2017.

Up until April 2013 dwellings undergoing major structural repairs for up to 12 months and those vacant for less than 6 months were eligible for a council tax exemption (Class A and C respectively). In April 2013 these exemptions were replaced with a new flexible discount which applied to all empty properties. Local authorities are now entitled to apply any level of discount from 0% to 100% to all empty properties. Where local authorities award zero discounts for empty properties there is less incentive for owners to report their property as empty. This could have led to some under reporting of some empty properties.
