Under current rules, landlords must now serve a Section 13 notice (Form 4A) (allowed only once a year) and give their tenants at least two months&#8217; notice before the revised rent can come into effect.<\/p>\n<p>Meanwhile, tenants can legally challenge the proposed rent increase and appeal to the Tribunal by submitting Form MR1 with a processing fee of \u00a347. With the new rules in effect, it\u2019s no surprise that landlords have lost some ground in these battles while tenants have gained some. Subsequently, in 2026, the number of cases ending in a reduction has increased to 64%.<\/p>\n<p>Read our <a href=\"https:\/\/www.benhams.com\/news\/landlords\/renters-rights-act-landlord-rent-increase-guide\/\">detailed guide for landlords explaining rent increases<\/a> after implementation of the <a href=\"https:\/\/www.benhams.com\/landlord\/renters-rights-act-implementation-roadmap\/\">Renters\u2019 Rights Act<\/a>.<\/p>\n<h2>Region-wise distribution of cuts in rent increases<\/h2>\n<div class=\"table-responsive mb20\">\n<table class=\"press-table textfLeft table-fixed font-14 w-100\" border=\"1\">\n<thead>\n<tr class=\"bg-table-blue\">\n<th style=\"text-align: center;\">Region<\/th>\n<th>Cases measured<\/th>\n<th>Rents reduced<\/th>\n<th>Median rate cut<\/th>\n<th>Median cut value (monthly)<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>London<\/td>\n<td>232<\/td>\n<td><strong>48.7%<\/strong><\/td>\n<td class=\"text-red\">9.2%<\/td>\n<td><strong>\u00a3150<\/strong><\/td>\n<\/tr>\n<tr>\n<td>Southern England<\/td>\n<td>384<\/td>\n<td><strong>60.9%<\/strong><\/td>\n<td class=\"text-red\">9.7%<\/td>\n<td><strong>\u00a3100<\/strong><\/td>\n<\/tr>\n<tr>\n<td>Eastern England<\/td>\n<td>280<\/td>\n<td><strong>58.2%<\/strong><\/td>\n<td class=\"text-red\">10.3%<\/td>\n<td><strong>\u00a3125<\/strong><\/td>\n<\/tr>\n<tr>\n<td>Midlands<\/td>\n<td>135<\/td>\n<td><strong>62.2%<\/strong><\/td>\n<td class=\"text-red\">8.9%<\/td>\n<td><strong>\u00a385<\/strong><\/td>\n<\/tr>\n<tr>\n<td>Northern England<\/td>\n<td>176<\/td>\n<td><strong>60.8%<\/strong><\/td>\n<td class=\"text-red\">9.1%<\/td>\n<td><strong>\u00a375<\/strong><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p>While in every other region of the country where a reduction to the proposed rent was determined stands close to ~60% of the total measured cases, in London less than half the cases (48.7%) saw a reduction.

Unlike fair-rent setups (pre-1989 regulated tenancies), where a formula is applied to determine the rent, assured shorthold (now periodic) and periodic tenancies follow an open-market model. This model only focuses on what a willing tenant would pay a willing landlord for the property in its current condition on the open market.<\/p>\n<p>The evidence that the Tribunal will accept and expects includes;<\/p>\n<ul class=\"icon-listing dot-icon mb10\">\n<li><strong>Comparable local rents:<\/strong> Unbiased research on the rents for similar properties in the immediate postcode\/postcodes by factoring in size, location and physical condition.<\/li>\n<li><strong>Proof of improvements\/repairs:<\/strong> Proof of all expenses, along with the photo\/videos of the improvements or repairs made to the property, can help justify a rent increase.<\/li>\n<li><strong>Previous Tribunal decisions:<\/strong> Citing specific outcomes from the Tribunal for comparable properties in the vicinity can help substantiate claims.<\/li>\n<\/ul>\n<p>It is also important to note that advertised or asking rents cannot be submitted as evidence, as the Tribunal will only consider achieved rents.<\/p>\n<h2>Longer the wait, bigger the loss<\/h2>\n<p>Among the sampled decisions, the median time taken from the date of application to the Tribunal\u2019s decision is 96 days (14 weeks) across all regions. In London, the median wait time is longer, up to 142 days (20 weeks). While a quarter of all cases have taken more than 24 weeks, there have been cases that have run well over a year.<\/p>\n<p>In the few instances where the panel upholds the rent increase, the date of increase is set from the day the decision is passed and not from the date of application. Since there is no concept of backdating or accumulating arrears, a longer wait time means loss of income.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.benhams.com\/news\/wp-content\/uploads\/2026\/08\/Section-13-rent-increases-and-tribunal-decisions_2.webp\" alt=\"How long do rent determination cases take\" width=\"1200\" height=\"675\" class=\"aligncenter size-full wp-image-29097\" srcset=\"https:\/\/www.benhams.com\/news\/wp-content\/uploads\/2026\/08\/Section-13-rent-increases-and-tribunal-decisions_2.webp 1200w, https:\/\/www.benhams.com\/news\/wp-content\/uploads\/2026\/08\/Section-13-rent-increases-and-tribunal-decisions_2-300x169.webp 300w, https:\/\/www.benhams.com\/news\/wp-content\/uploads\/2026\/08\/Section-13-rent-increases-and-tribunal-decisions_2-1024x576.webp 1024w, https:\/\/www.benhams.com\/news\/wp-content\/uploads\/2026\/08\/Section-13-rent-increases-and-tribunal-decisions_2-768x432.webp 768w, https:\/\/www.benhams.com\/news\/wp-content\/uploads\/2026\/08\/Section-13-rent-increases-and-tribunal-decisions_2-150x84.webp 150w\" sizes=\"auto, (max-width: 706px) 89vw, (max-width: 767px) 82vw, 740px\" \/><\/p>\n<h2>How an experienced agent can help landlords win<\/h2>\n<p>Instructing an experienced London-based lettings agent like Benham and Reeves gives landlords a massive advantage.
