Searchland's analysis has revealed a notable finding regarding planning applications in the UK. According to their data, the proportion of applications approved after undergoing the appeals process, following initial rejection, reached a five-year low of 18% in 2022.

Delving into the details, Searchland examined the annual volume of planning applications submitted, tracking the rates of rejection and the outcomes of subsequent appeals. Last year, a significant number of 73,515 applications faced rejection nationwide, while a considerably higher count of 560,591 applications received approval.

The reasons behind these rejections encompass various factors. They range from concerns about privacy infringement due to encroachment on neighboring properties to the loss of natural light. Environmental considerations, such as the preservation of trees and wildlife habitats, also contribute to the refusal of applications. Other factors leading to rejections include the use of hazardous building materials, restrictions on road access, and broader safety concerns like air pollution.

It is worth noting that applications involving listed buildings are particularly prone to rejection. Such projects necessitate additional consents and adherence to specific planning controls, thereby increasing the likelihood of refusal.

Out of the significant number of 73,515 rejected applications, a mere 2,210 opted to appeal, constituting just 3% of all rejected applications. Unfortunately, only 392 of these appeals succeeded in overturning the initial decision, resulting in a success rate of merely 18%. This marks a significant decline from the previous year's success rate of 28% and a noteworthy drop from the peak of 30% observed in 2020.

Mitchell Fasanya, co-founder and CEO of Searchland, offered insights into the matter, stating, "The reasons behind a planning application's rejection can be diverse, ranging from basic concerns such as encroachment on neighboring properties to more complex aspects such as material choices and broader environmental considerations."

"While ideally these issues should have been addressed prior to application submission, the appeals process provides an opportunity to address any raised concerns and reapply," Fasanya added.

Nevertheless, the figures compiled by Searchland depict a challenging landscape. They indicate that the chances of overturning a rejected application have reached their lowest point in the past five years. With less than one in five appeals achieving success, aspiring developers now face a more daunting task when navigating the planning process.
