Over half of tenants are likely challenge rent increases under the incoming Renters' Rights Bill (RRB), according to new research by LRG.

The Q1 2025 Lettings Report from LRG found that 53% of tenants would likely contest a rent rise, with 28% describing themselves as very likely to do so.

Allison Thompson, National Lettings Managing Director at LRG, said: “The Renters’ Rights Bill represents a significant change for the private rented sector, but it’s important to recognise that not all tenants will be looking to challenge rent increases. Many already trust the process, especially where landlords have shown a track record of fair, market-aligned reviews. Our data reflects that.

“At the same time, we must be realistic. Reforms like this only work if they are clear and consistent. Without the right safeguards, we risk seeing the same issues that have emerged in Scotland: growing backlogs, rising disputes, and reduced supply. That’s why we believe it’s essential that the House of Lords' proposed amendment, linking rent increases to recognised indices, is included in the final legislation. This would provide much-needed clarity and reassurance for landlords and tenants alike.”

Despite this, landlords remain confident that those who take a proactive and professional approach by setting rents in line with the market, with 62% of landlords surveyed seeing potential benefits in a clearer, more transparent system. Meanwhile, 75% of tenants say that limiting increases and allowing appeals will improve affordability.
