This is partly due to it's attractiveness to commuters working in London.
Winchester (10.54), London (10.06), Cambridge (9.9) and Bath (9.77) make up the top five least affordable cities. The London average figure disguises considerable variations across the capital with central boroughs being significantly less affordable than the Greater London average.
Lichfield (7.53) and York (7.50) are the least affordable cities outside southern England.
At the other end of the scale, with average property prices of £113,302, 3.8 times average earnings for the city, Londonderry is both the UK's most affordable and least expensive city.
Northern Ireland cities Belfast (4.42) and Lisburn (4.64) are the 4th and 6th most affordable cities respectively, due primarily to the relatively low house prices in the country.
Northern English and Scottish cities make up the remainder of the top 10 most affordable cities. Bradford (4.31), Hereford (4.55), Durham (4.73), Lancaster (4.89) and Carlisle (5.03) in England. Stirling (4.11) and Glasgow (5.07) in Scotland.
