Construction License: A Practical UK Guide
If you’re starting a conservatory, an extension or any building project, you’ll hear the term “construction licence” a lot. It’s not just paperwork – it’s the legal green light that lets you and your builder work on site without breaking the law. In this guide we’ll break down what a construction licence is, when you need one, how to get it and what can go wrong if you skip it.
When Do You Need a Construction Licence?
Any work that changes a building’s structure, adds new rooms or alters load‑bearing elements usually requires a licence. Typical examples include:
- Adding a conservatory or sunroom.
- Extending the ground floor beyond the permitted‑development limits.
- Replacing foundations or major roof work.
- Changing the use of a space, for instance turning a loft into a bedroom.
How to Apply for a Construction Licence
The process is straightforward if you follow the steps:
- Check if you need one. Use your local council’s online tool or give them a call. They’ll tell you whether the work falls under permitted‑development.
- Choose a registered contractor. In the UK, a builder must be registered with a recognised scheme (e.g., CHAS, Constructionline). This ensures they’re qualified to submit the licence.
- Gather the paperwork. You’ll need detailed plans, structural calculations and proof of any required approvals (like party‑wall agreements).
- Submit the application. Most councils now accept online submissions. Pay the fee – it’s usually a small percentage of the project cost.
- Inspection. After the work starts, a Building Control Officer may visit to check compliance. Keep the site tidy and accessible.
Once the licence is granted, you’ll receive a document that outlines the conditions you must meet. Keep it on site – you’ll need it for final inspections and for any future resale.
Remember, a construction licence is different from planning permission. Planning deals with how the building looks and fits into the neighbourhood. The licence focuses on safety, structural integrity and compliance with building standards. Skipping the licence can lead to fines, demolition orders or trouble when you sell the house.
Here are a few common pitfalls and how to avoid them:
- Assuming “small job” doesn’t need a licence. Even a modest loft conversion can trigger a licence if it alters load‑bearing walls.
- Using an unregistered contractor. This can delay the application and may result in a rejected licence.
- Missing deadlines. Licences are usually valid for 12 months. If you stall, you’ll need a new application.
- Ignoring conditions. Some licences require specific materials or fire‑rating checks. Not following them can cause costly re‑work.
Finally, keep an eye on changes to UK building regulations. The government updates standards roughly every few years, especially around energy efficiency and fire safety. Staying current helps you avoid surprises mid‑project.
