Price-to-rent ratio and rental yield are the same underlying relationship, just expressed the other way round. Yield asks "what percentage of the purchase price does a year's rent bring back." Price-to-rent ratio asks "how many years of rent would it take to equal the purchase price." Divide the price by a year's rent and that's the ratio; divide a year's rent by the price and multiply by 100 and that's the yield. If you already have one, you already have the other.

The current UK figure

Right now, the average UK property costs around £340,000 to buy and rents for around £1,300 a month, £15,600 a year. £340,000 divided by £15,600 works out to a price-to-rent ratio of roughly 21.8, meaning it would take about 22 years of rental income to equal the purchase price at the national average.

That single number moves around by area more than most people expect.

Why the ratio varies so much by postcode

A postcode district like BD1 in Bradford currently averages £55,000 to buy against £695 a month in rent, £8,340 a year, a price-to-rent ratio of about 6.6. The gap between 6.6 and the national 21.8 isn't a data error, it's the same gap that shows up as a 15.2% gross yield in BD1 against a roughly 4.6% national average, just read the other way round.

Lower purchase prices relative to rent mean a lower ratio and a higher yield; higher purchase prices relative to rent mean a higher ratio and a lower yield. Expensive cities with strong rental demand can still carry high ratios, because the price side of the equation has run further ahead of what tenants actually pay in rent.

Check the ratio for a specific postcode

Rather than a single national figure, every UK postcode district's current average buy price, rent, and resulting yield, the inverse of price-to-rent ratio, is on the interactive map. Divide any postcode's average buy price by twelve times its average rent to get that area's own price-to-rent ratio directly, or browse the highest-yield (lowest price-to-rent ratio) postcodes right now.
