This Section 191 Lawful Development Certificate case study shows how a refused LDC application can still be successfully overturned on appeal when the correct evidence is presented in the right way.
In this appeal success, HEAL Planning secured approval for a Section 191 Certificate of Lawful Existing Use for a site in Buckinghamshire, close to Great Brickhill in the Milton Keynes area. The application related to the existing residential use of buildings as self-contained apartments, including a mix of studio, one-bedroom and two-bedroom units.
The local authority had refused the Lawful Development Certificate on the basis of evidence. Buckinghamshire Council concluded that there was insufficient proof to demonstrate, on the balance of probabilities, that the buildings had been continuously used as residential apartments for a period of four years or more prior to the application date.
This case highlights a crucial point about Section 191 Lawful Development Certificates. Unlike planning applications, LDCs are not assessed on planning merit, design quality, or whether a council considers the use to be acceptable. They are decided purely on evidence. The key test is whether the applicant can prove that the use is lawful through factual documentation.
Following the refusal, the client contacted HEAL Planning and arranged a free, no-obligation consultation with one of our specialist Planning Appeal Assessment Officers. During this assessment, the refusal reason was reviewed in detail, and it was confirmed that the council’s decision could realistically be challenged through the appeals process.
A full written appeal proposal was then prepared, allowing the client to fully understand the strategy, evidence requirements and likelihood of success before proceeding.
The appeal was submitted to the Planning Inspectorate, the government body responsible for determining planning appeals and Lawful Development Certificate appeals in England.
The appeal decision was issued on 24th November. One of the most notable aspects of the decision was the Inspector’s confirmation that a site visit was not required. The Inspector stated that the appeal could be determined solely through an assessment of documentary evidence, making a physical inspection unnecessary.
Importantly, the Inspector also confirmed that appeals are determined based on all evidence available at the appeal stage. This means appellants are entitled to submit additional evidence, even where it was not included with the original LDC application. This clarification was a critical turning point in the case.
In support of the appeal, HEAL Planning submitted substantial additional documentation, including updated statutory declarations, tenancy agreement extracts and supporting bank statements. The Inspector accepted that the cumulative body of evidence demonstrated continuous residential occupation of the units for the required four-year period prior to the LDC application.
As a result, the Inspector concluded that the residential use was immune from enforcement action under the four-year rule. This meant the council could no longer take enforcement action against the existing residential use.
The Inspector also made positive comments regarding the council’s handling of the appeal, acknowledging that officers had carefully considered the additional evidence and correctly accepted that it overcame the original refusal reason.
Ultimately, the Inspector found that the refusal of the Section 191 Lawful Development Certificate was not well-founded. The appeal was allowed, and a Lawful Development Certificate was formally issued confirming that the residential use of the buildings was lawful.
This case demonstrates that a refusal of a Section 191 Lawful Development Certificate does not have to be the end of the process. With the right appeal strategy, expert assessment and properly structured evidence, it may still be possible to secure a successful outcome through the Planning Inspectorate.
