Solicitors for planning & zoning advice — navigating planning law to unlock commercial property potential across England and Wales

Planning permission is a formal grant of consent by the local planning authority for a specific development or change of use. Lawful use, by contrast, is established by the passage of time — if a use or development has been carried on continuously for a specified period (typically 10 years for changes of use, 4 years for operational development) without enforcement action, it becomes lawful. A lawful development certificate confirms this status. The distinction matters enormously for commercial property: a tenant may have been using premises for a purpose that does not match the planning permission, but if the use has been continuous for 10 years, it may be lawful. Our lease legal audits and change of use consent solicitors regularly advise on these distinctions.

Permitted development rights are set out in the Town and Country Planning (General Permitted Development) (England) Order 2015. They allow certain types of development and changes of use without the need for a full planning application. For commercial property, the most relevant permitted development rights include changes between certain use classes (for example, from office to residential under Class MA), certain extensions and alterations, and the installation of plant and machinery. However, permitted development rights can be removed by the local planning authority through an Article 4 direction, and they may be subject to prior approval requirements. Our change of use consent solicitors advise on whether permitted development rights apply to your property and circumstances.

An enforcement notice is a formal document served by the local planning authority alleging a breach of planning control. It specifies what the breach is, what steps must be taken to remedy it, and the period for compliance. It is critical to act quickly — there are strict time limits for appealing, and failure to comply is a criminal offence. The first step is to establish whether the enforcement notice is valid: does it correctly identify the breach? Is the period for compliance reasonable? Are there grounds for appeal (for example, that the use is in fact lawful, or that planning permission should be granted)? Our commercial lease disputes solicitors have extensive experience handling enforcement matters, including coordinating with mediation where negotiation with the planning authority may be more effective than formal appeal.

Yes, and this is an area where many tenants and landlords are caught out. A section 106 agreement is a legal agreement between the landowner and the local planning authority that imposes obligations relating to the development — for example, restrictions on use, requirements to provide affordable housing, or contributions to infrastructure. Because section 106 agreements bind the land, they bind successors in title, including tenants. A tenant who breaches a section 106 obligation may be at risk of enforcement action by the planning authority, and may also be in breach of lease. Our lease due diligence process includes a review of any section 106 agreements affecting the property, and our drafting landlord-friendly lease solicitors ensure that section 106 obligations are properly addressed in new lease agreements.

A lawful development certificate (LDC) is a formal confirmation from the local planning authority that a use, operation, or development is lawful. There are two types: an LDC for an existing use or development, and an LDC for a proposed use or development. For commercial property, an LDC for existing use is often needed when selling or refinancing a property where the planning history is unclear — for example, where the use has been established by the passage of time rather than by express planning permission. An LDC for a proposed use confirms that the proposed change does not require planning permission (for example, because it benefits from permitted development rights). Our lease legal audits and change of use consent solicitors regularly prepare and submit LDC applications.

Planning and zoning are fundamental to commercial property value. A property with a flexible use class and development potential is worth considerably more than one constrained by restrictive planning conditions or an unfavourable zoning designation. Conversely, properties with unresolved planning issues — an expired permission, an uncertain lawful use, or an outstanding enforcement notice — can be difficult to sell or finance. Our property acquisition support and lease risk assessment services provide a full evaluation of planning-related value implications. For landlords and investors, our portfolio management support service includes ongoing planning reviews to protect and enhance asset value.
