The last time rents had hit that mark were in November 2017 after 18 month of decline and they slipped to a low of 0.9% between July and November 2018.
Although average rents across the UK were up last year, the rise was 1.2% in Wales and 0.6% in Scotland.
In London, the year-on-year increase was 1.2%, a regional climb of 0.2% from 1% in November.
In monetary terms, UK rents showed a £7 a month rise for every £500 of rent between December 2018 and last December.
