Overview

We have recently secured a series of successful outcomes involving HMOs, self-contained flats and the regularisation of established residential uses.

The cases included:

·       a lawful development certificate confirming the lawful use of a property in Enfield as a five-bedroom HMO

·       a lawful development certificate confirming the lawful use of a property on Perham Road in Hammersmith & Fulham as seven self-contained flats

·       retrospective planning permission in Brent for a larger HMO following enforcement proceedings and an earlier refusal

Although each case involved a different planning route, the underlying theme was consistent: these were evidence-led planning matters requiring careful risk assessment, detailed review of historic records and a clear submission strategy before any formal application was made.

That is particularly important in lawful development certificate and retrospective regularisation cases. Where a client is already relying on an established use without clear planning confirmation, the decision to submit an application needs to be approached carefully. If the Council refuses the application, the client may be left not only with an unsuccessful decision, but also with increased exposure to enforcement risk.

For that reason, we will often recommend an initial evidence review before a formal application is submitted. That first stage allows us to assess whether the available evidence provides a sufficiently strong basis to proceed, identify any gaps, and ensure the case is properly assembled before the Council is asked to determine it.

The Planning Context

Residential regularisation cases can arise in a number of ways. A property may have been used as an HMO for several years without a clear planning record. A building may have been divided into self-contained flats, but the owner may need formal confirmation of the lawful planning position. In other cases, the Council may have already raised enforcement concerns, requiring a prompt and carefully managed response.

These matters can be commercially significant for landlords, investors and property owners. The outcome may affect property value, future saleability, mortgageability, licensing, enforcement exposure and long-term investment strategy.

The quality of the planning strategy and the evidence base is therefore critical.

Lawful Development Certificate for a Five-Bed HMO in Enfield

In the Enfield case, we secured a lawful development certificate confirming the lawful use of the property as a five-bedroom HMO.

The central issue was evidence. The application needed to demonstrate that the HMO use had existed for the relevant period and had not been abandoned or interrupted in a way that would undermine the claimed planning position.

This required a detailed review of historic material across a long period. The client had a substantial number of files and records, but the existence of a large evidence base is not sufficient in itself. The material had to be reviewed, organised and presented in a coherent way.

The strategy was to begin with an initial evidence review. That allowed us to assess whether the case was strong enough to justify proceeding and whether any further material was required before the formal submission was made.

This stage helped manage the client’s risk. Rather than submitting prematurely, the application was built properly from the outset, with the evidence reviewed, refined and assembled into a clear submission.

The Council accepted the case and issued the certificate.

Lawful Development Certificate for Seven Self-Contained Flats in Hammersmith & Fulham

We also secured a lawful development certificate confirming the lawful use of a property on Perham Road in Hammersmith & Fulham as seven self-contained flats.

Again, the decisive issue was the strength, consistency and presentation of the evidence.

The application required a careful review of a substantial evidence base across the relevant period. It was necessary to work through several sets of material with the client, review the documents in detail, identify whether anything further was needed, and ensure that the final submission clearly explained the planning position being claimed.

It was also important to make sure the evidence corresponded with the layout and use shown on the drawings. In lawful development certificate cases involving self-contained flats, it is not enough to assert that a building has been used as flats. The evidence should demonstrate what the units were, how they operated, and how the documentary record relates to the physical arrangement of the building.

The application was therefore structured around a detailed evidence trail rather than a broad assertion of historic use.

The Council accepted the case and issued the certificate, confirming the lawful use of the property as seven self-contained flats.

Retrospective Planning Permission for a Larger HMO in Brent

The Brent case required a different strategy.

The property was operating as a larger HMO without planning permission. The Council had commenced enforcement proceedings, so the client needed a prompt and carefully framed planning response.

We submitted a retrospective planning application directly in response to the enforcement position. The purpose of the application was to regularise the existing use and secure planning permission for the HMO.

During the application, there was significant liaison with the Council. Plans were amended more than once and the proposal was actively managed through the determination process.

The Council ultimately refused the first application. However, the refusal did not indicate that the planning case was incapable of being resolved. The decision identified a number of specific matters that needed to be addressed.

We therefore amended the scheme quickly to respond directly to the refusal reasons and submitted a revised application promptly. The second application succeeded, and planning permission was secured in April 2023.

This outcome demonstrates the importance of analysing a refusal carefully. A refusal will sometimes reveal that the Council’s concerns are fundamental. In other cases, it clarifies the specific issues that need to be addressed through a targeted amendment strategy.

In this case, the appropriate response was to move quickly, maintain communication with the Council, address the refusal points directly and continue to present the proposal as one capable of approval.

Strategic Approach

Across all three cases, the successful outcomes were achieved through a similar approach.

1. Evidence review before submission

For the lawful development certificate cases, the first stage was an evidence review. This allowed the clients to understand the strength of their position before entering a formal process that could increase enforcement exposure if unsuccessful.

2. A submission built around the evidence

The strongest lawful development certificate applications are not built on general assertions. They are built on evidence. That evidence may include tenancy records, utility records, council tax records, correspondence, photographs, licensing material, floor plans and other documents showing how the property was used over time.

The planning work lies in understanding what the documents prove, where any gaps exist, and how the evidence should be presented so that the Council can reach the correct conclusion.

3. Evidence tied to the plans and the use being claimed

In both lawful development certificate cases, it was important to ensure that the evidence aligned with the planning position being advanced. The documents needed to correspond with the layout, number of units or rooms, pattern of occupation and specific use being claimed.

4. Prompt and strategic action where enforcement is involved

The Brent HMO case required a proactive response. Once enforcement proceedings had commenced, the planning strategy needed to be progressed quickly and with a clear understanding of the Council’s concerns. When the first application was refused, the refusal reasons were analysed and addressed through a revised application.

5. Control of the planning narrative

In each case, it was important to present the case positively and clearly. That meant identifying why the proposal or claimed use should be accepted, what the evidence demonstrated, and how the Council could reasonably reach a favourable decision.

Outcome

We secured successful outcomes in all three cases:

·       a lawful development certificate for a five-bedroom HMO in Enfield

·       a lawful development certificate for seven self-contained flats in Hammersmith & Fulham

·       retrospective planning permission for a larger HMO in Brent following enforcement action and refusal

Together, these cases demonstrate the value of a careful, evidence-led planning strategy where residential uses need to be regularised, confirmed or protected.

They also show why early advice matters. By reviewing the evidence before submission, identifying risk and building the case properly, clients can make better decisions before entering a potentially exposed planning process.

For property owners, landlords and investors dealing with HMOs, self-contained flats, enforcement risk or historic residential uses, the right strategy can make the difference between uncertainty and a secure planning position.
