House prices are set to rise by almost a fifth in the next five years, property firm Savills has predicted.

The estate agency said property values would increase 19.3% by 2020 across the UK. However, some areas will fare better than others.

In London property prices are expected to grow by 10.4% during the same period with the suggestion that those in the capital would be unable to afford any greater rises.

Property prices have already risen by 61% since 2010 and new mortgage restrictions mean Londoners are increasingly limited in the amount they can borrow.

Savills’ Katy Warrick said: “This has huge consequences for Londoners, whose finances are being stretched further and further as house prices continue to rise at a disproportionate rate to the rest of the country.

“This value gap simply cannot widen at this rate indefinitely, which is why we expect mainstream London to see just 10.4% growth over the next five years, compared to 19.3% across the UK as a whole.”

Warrick said that despite the predicted slowdown a growing number of people would be denied the chance to get onto the property ladder.

“Mortgage regulation is one of the main constraining factors to further house price growth. This new lending environment is one of loan to income caps, stress testing of borrowers’ affordability and capital repayment requirements,” she said.

“Coupled with fast-moving house prices against a context of limited income growth, this means higher deposits are required. Jump forward five years and we expect that prices will grow just 10.4%, as fewer first time buyers will have been able to access home ownership for these reasons.”
