Properties available within 12 months are currently seeing the largest demand from renters compared to those available more immediately, according to Barrows and Forrester.
The figures show that the current issues caused by COVID-19 are causing many tenants to look to the long term, outlined the firm.
Barrows and Forrester believe that this trend is accountable to lockdown restrictions and the threat of catching the virus.
Almost half of new tenants in Prime London are from EU
The data shows that 38% of all rental properties listed as available within the next year already seeing a let agreed on them.
In contrast, tenant demand for rental homes that are immediately available is far lower, with just 24% of properties listed as such already seeing a let agreed on them.
Similarly, demand for rental properties available within one and three months sits at 23%, with those available in six months the lowest of all at 21%.
This current trend is prominent across all bar three of the 23 major UK cities, which are Belfast, Bournemouth and Aberdeen.
The analysis was of 50,000 listings conducted by Barrows and Forrester.
James Forrester, managing director of Barrows and Forrester, said: “The rental market is a strange place to be at the moment for tenants looking to secure a property.
“While lockdown restrictions aren’t preventing them from house-hunting per se, the ongoing uncertainty of the pandemic is presenting its own issues.
“Many are in doubt over their current financial situation and whether they’ll even have a job to return to, while it’s also unclear as to whether the growing trend of remote working will remain once we can go back to our places of work.
“As a result, many tenants are wary about entering into lengthy tenancy agreements across our major cities when they may be able to secure a more affordable option in the surrounding areas.
“This has caused a major shift in rental market trends with many choosing to sit tight and plan for life after COVID-19.
“This is a stark contrast to traditional market speeds where you could quite literally blink and miss a newly listed rental property within hours of it being listed because demand was so high.
“As we continue to roll out the vaccine, we should see stability return and the rental market revert back to a sense of normality.”
