Home renovation can be an exhilarating venture for UK homeowners, yet not all renovations can be undertaken without first seeking planning approval from local authorities to comply with building regulations and preserve the environment. In this article we’ll look at which renovation projects typically need approval as well as how best to obtain it.


    Residential property extensions frequently require planning approval if they exceed certain size restrictions or alter the appearance of the home. For advice on planning permission from experienced contractors, contact LocalTradesUK for a consultation. Examples of projects which could require planning approval for expansions are:

    Single-Storey Extensions

    Constructing a single-storey extension on either the rear or side of a property can significantly expand living space; however, extensions exceeding specified dimensions (height/depth) usually require planning approval.

    Two-Storey Extensions

    Two-storey extensions involve adding two additional floors to a property and typically have more of an effect on its environment than single storey ones. Planning permission may be required for such expansions to ensure compliance with building regulations and local planning policies.

    Converting loft space to habitable space such as an extra bedroom or home office is an increasingly popular renovation project, though any that alter the roof structure or exceed certain size limits may need planning approval.


    Although conservatories provide valuable additional living space and aesthetic upgrades to any property, they may require planning permission in certain instances. Size, location and proximity to neighbouring properties all play a part when determining if planning approval is needed for a conservatory installation. Generally, permitted development status applies if certain criteria such as height restrictions and floor area limits are met.


    Constructing buildings like garden sheds, garages or summerhouses can enhance outdoor living spaces but may require planning permission depending on their size, location and intended use. Buildings exceeding certain dimensions such as height or floor area; located within designated conservation areas or flood zones may need approval before being constructed.

    Alterations to the Exterior

    Any significant exterior modifications, such as adding balconies, changing windows or doors or altering rooflines, require planning approval in order to comply with local planning policies and regulations. Alterations that alter the appearance of the property or its surroundings could require planning approval as well.

    Listed Buildings and Conservation Areas

    Properties located within conservation areas or listed buildings are subject to additional regulations designed to preserve their historic and architectural significance. Any alterations or renovations affecting listed buildings or properties within conservation areas typically require planning approval and additional review from conservation officers to ensure they respect the character and heritage of their surroundings.

    Process of Achieve Planning Approval for Home Renovations:

    Securing planning approval for home renovation projects involves several steps.

    Before undertaking any renovation project, it is wise to consult with local planning authorities or qualified professionals in order to ascertain whether planning permission is needed and assess its likelihood.

    Preparation of Planning Application

    If planning permission is required for your renovation project, submit a comprehensive planning application which includes detailed drawings, plans and supporting documents that outline its impact on both its immediate environment as well as on any surrounding communities.

    Submit the Planning Application

    Submitting your planning application with its required application fee will initiate a review process in which neighbours and other stakeholders have an opportunity to offer input or provide any objections they might have about it.

    Planning Decision

    Once submitted, your local planning authority will evaluate your application against all relevant policies, regulations, and considerations to make a decision to approve, deny, or request modifications for your renovation project.

    Appeals Process

    Homeowners who find their planning application denied or conditions imposed are entitled to appeal through an appeals process administered by the Planning Inspectorate.


    Renovation projects can dramatically transform living spaces and add significant value to properties, but to do it properly and comply with regulations and local planning policies it’s essential that homeowners go through an exhaustive planning permission process. By understanding which renovations typically require planning permission in the UK and following the appropriate procedures to obtain approval, homeowners can embark on renovation projects with confidence knowing they’re contributing to sustainable development and preservation in their community. Consulting local planning authorities or professionals specialising in planning and development may offer invaluable guidance during the application process and help facilitate successful home renovations.
