Under the Building Regulations 2010, anyone building a new property or extending an existing one must obtain building regulations approval from their local authority or an approved building control body.

If you're a local authority or building control company and need to understand whether a proposed development could affect our assets, you're in the right place.

You can use our online application form to submit details of your customer's proposed development quickly and easily.

Once we've reviewed the information, we'll let you know whether the proposed works may affect any of our water mains or public sewers. We aim to respond within 10 working days.

How much does it cost?

There is no charge for this service.
