If you’re planning a home extension, loft conversion, garage conversion, or any major building work in Leeds or Bradford, understanding local planning permission rules is essential. Getting it right from the start will save you time, money, and potential legal headaches.
Last updated: September 2026
What is planning permission?
Planning permission is approval from your local planning authority for certain changes to a property. It is separate from Building Regulations approval, and some projects need both.
Do you always need planning permission?
Not necessarily. Some work may fall under Permitted Development Rights, provided the property and proposed design meet all current limits and conditions.
Projects that may qualify include:
- Small single-storey rear extensions within permitted limits
- Loft conversions within the relevant roof and volume limits
- Garage conversions where the building footprint is not enlarged
- Certain outbuildings, subject to position, height and use
Permitted development rights can be restricted for listed buildings, flats, maisonettes, conservation areas or properties affected by an Article 4 direction. Always confirm the position for your property before work starts.
Local guidance for Leeds and Bradford
Leeds City Council and Bradford Council apply national planning law alongside local policies. Conservation areas, listed buildings, heritage settings, flood risk and the design of neighbouring properties may affect an application.

How to apply
- Confirm whether planning permission or prior approval is required
- Prepare accurate drawings and supporting information
- Submit the application through the Planning Portal or local council
- Check the current application fee on the official Planning Portal
- Allow time for consultation and a decision; straightforward applications are often targeted within eight weeks, but timescales vary
Planning permission and Building Regulations are different
Planning considers the development's impact and appearance. Building Regulations cover matters such as structural safety, insulation, fire safety and drainage. Approval under one system does not automatically provide approval under the other.

Important
Planning rules, fees and local policies can change. This guide is general information, not legal or planning advice. Confirm requirements with the relevant council or a qualified planning professional before starting work.
Plans Required for Extensions and Dormer Loft Conversions
Up Close Construction requires detailed architectural and construction plans for every house extension and dormer loft conversion before we can accurately price or begin the work. This applies even where the project may fall under permitted development and does not require a planning application. If you do not already have suitable plans, we can recommend an independent architect. The architect will contact you, confirm their costs and invoice you directly. The completed plans belong to you, and you are not required to use Up Close Construction as your contractor.
