Government data suggests annual rental growth remained at 1.3% across the UK for the fifth consecutive month in October, but there are warnings that the rate of increase could accelerate.

Figures from the Office of National Statistics found that average private rental prices rose by 1.3% in the 12 months to October, unchanged since May.

Rents in England grew by 1.4% in the 12 months to October, up slightly from 1.3% in the year to September.

Annual rental growth was unchanged in Wales, up 1.2%, and slowed from 0.8% to 0.7% in Scotland.

Rents increased by 1.9% in Northern Ireland.

However, Belvoir is warning that rents could rise further as its offices witness a lack of stock.

Analysis of 140 offices in the agency franchise found that 15 reported stock shortages at the end of the third quarter as fewer landlords are purchasing and some are still selling up.

More than half of Belvoir offices confirmed an increase in landlords offloading four to five properties and the percentage of offices reporting no landlords buying has doubled since 2016, Belvoir said.

The agent warned that there are more tenants than properties to rent in most areas it covers.

Its office data showed that rents increased by 4.75% annually to £819 as of the end of the third quarter.

Belvoir’s analysis found that increasing numbers of families are renting out of choice rather than necessity.

Three quarters of Belvoir offices reported an increase in the number of families renting.

Agents reported that those renting weren’t just doing so because they couldn’t afford to buy, but many rented due to job moves, lack of social/council housing, renting as a temporary solution to avoid losing a sale, or the inability to find a property they wanted to buy.

It was also claimed that these types of tenants preferred the flexibility of renting a larger property in an area that they would not be able to buy.

Dorian Gonsalves, chief executive of Belvoir, said: “The survey suggests that the idea that families are renting purely due to affordability issues isn’t necessarily true, as many are finding it a practical solution to their current issues.

“However, for those that are renting in the private sector because of a lack of social housing, this suggests that if the proposed abolition of Section 21 goes ahead and there are less properties to rent, it could seriously damage the very tenants the Government is trying to help.

“Tenants and landlords that continue to let are doing so amicably and at affordable rents.

“The key issue moving forward is that in most areas there are more tenants than there are properties to rent. If this trend continues, it is likely to put upward pressure on rents.”
