Private rental prices paid by tenants in Britain rose 2.1 per cent in the 12 months to March, according to the latest figures from the Office for National Statistics.
Broken down by country, rental prices grew by 2.1 per cent in England and Scotland, and 0.8 per cent in Wales.
Rents increased in all the English regions over the year, with the largest in London at 3.2 per cent; if the capital were removed the all-Britain figure would be 1.5 per cent.
Meanwhile a separate index by lettings agency Your Move claims a high figure for the annual yield received by landlords in Scotland. It is now 9.7 per cent on average in the year to March, up from 7.2 per cent a year ago.
This is equal to £15,000 per property before any mortgage payments or maintenance costs, but taking into account property price growth and void periods between tenants.
Buy-to-let investors in Edinburgh have experienced the strongest annual returns in the last year of 13.4 per cent - equivalent to £27,135 in cash terms, claims Your Move.
