This month’s data - which is claimed to be the largest monthly survey of private tenants in the UK - shows only London (up 2.4 per cent) and the south east (up three per cent) registering increases of more than two per cent.
East Anglia and the south west, both of which have been recording strong growth in recent months, have seen a slow down in August with rents in East Anglia increasing by just one per cent and the south west recording a drop of 0.9 per cent.
Rents were also lower in Scotland, Wales, the north west and north east of England as well as the East Midlands.
The biggest fall in rental prices is in the north west where rents paid for new tenancies last month were, on average, 3.5 per cent lower than those paid on new tenancies in July.
Rents were up by 1.9 per cent in the West Midlands and by 1.0 per cent in the East Midlands and Northern Ireland.
