The national average monthly rent for a one-bedroom flat has fallen from around £533 a month to £519 since the summer. This figure hides huge variations, ranging from £373 in Wales to £2,336 in Inner London, where rental returns have been falling for nine months. For larger properties, average rents nationally held steady at around £656 for a two-bedroom flat and £859 for a three-bed semi. Surveyors in some regions reported modest rises in average rents.
