Rents are increasing at the fastest rate in five years, and the signs are that they will rise further, unless significantly more is done to boost the supply of much-needed rental homes.

The latest Office for National Statistics figures show that the average newly advertised rental price has reached £969 a month following gains across the UK.

Sarah Coles, senior personal finance analyst at Hargreaves Lansdown, said: “Rents are rising faster than any time in the past five years, forcing tenants to choose between squeezing their spending even harder, or uprooting their life. Either way, they’ll end up worse off.”

Conscious of the widening supply-demand imbalance and the impact it is having on the private rented sector (PRS), the Association of Independent Inventory Clerks (AIIC) is now calling on the government to include the provision of more new rental homes in all parts of the country, as part of its levelling up agenda.

The AIIC says that, in certain parts of the country, the PRS is coming dangerously close to running out of homes completely, and as a result the Boris Johnson government must extend its flagship policy to the rental market as well.

“We’ve had reduced social housing for the last 20 years, and at the same time the many restrictions on landlords have reduced the growth of the PRS as a compensatory mechanism to fill this shortfall,” Daniel Evans, chair of the AIIC, said.

“We also need to look at how unaffordable housing across the country has locked many first-time buyers out of getting on the property ladder, leading to the average first-time buyer age going up to the mid-30s.”

Further to this, he adds, is the larger demand for rental homes from the younger generations – who in many cases have to, or want to, rent for the long-term.

“All of these things taken together means demand is very, very high – probably as high as it’s ever been for many decades – while supply just simply isn’t keeping pace. Such a gap between supply and demand can not be sustainable for the long-term,” Evans added.

While Evans says that Build to Rent is helping to plug this gap somewhat, it is mostly focused on central urban areas and prime postcodes to maximise ROI – and still only accounts for about 2-3% of the overall market.

He continued: “On its own, BTR is nowhere near enough to address the chronic stock shortage, particularly in suburban and countryside locations where the stock shortage is most acute and where BTR schemes are much rarer.

“Add to this a lack of brownfield and greenfield sites for development and you have a major problem when it comes to creating enough stock.”

Evans believes that the long-term problem with such a dichotomy between supply and demand is that prices continue to soar. “Rocket-like rent rises will simply end up making rental properties similarly unaffordable to generation rent, and they may decide to stay living with their parents for longer.”

The stock shortage, which is already severe, could be made even worse by further restrictions on landlord, including the removal of Section 21. This could serve, Evans says, to drive more landlords out of the market, worsening the stock-side crisis even further.

The AIIC believes that the government needs to create policies to promote affordable housing development (with open space available) in non-urban areas.

“It also needs, as the National Residential Landlords Association has pointed out, to encourage investment in the PRS rather than further legislation to remove landlords and reduce profitability,” Evans explained.

There also needs to be an uptick in social housing, to reduce the burden of pressure on private landlords, and offer incentives to landlords when it comes to improving the eco-friendliness of their homes – with many landlords fearing the improvements required will cripple them financially.

Evans added: “Landlords also need a major say in the rental reform outlined in the Levelling Up White Paper, which is expected to be fleshed out in the White Paper on Rental Reform in spring.

“We can’t completely disincentivise landlords, because the PRS will start to crumble and more rogue landlords will be able to slip through the net. New legislation and reforms can be welcome, but only if they bring everyone along and have long-term benefits for all parties – instead of merely being used to score political points.”
