Self-build and custom-build homes
The Building Safety Levy (BSL) will come into effect on 1 October 2026. It is a tax on new dwellings and new bedspaces in purpose‑built student accommodation (PBSA).
Developers must pay the levy on certain building control applications or notices before completion or occupation of the building. The Council will collect the levy.
The Building Safety Levy (England) Regulations 2025 sets out how the levy will operate.
About self-build homes
A self-build home allows the future residents to organise the home's design and construction. This could involve independently employing an architect and builder.
About custom-build homes
Custom-build homes are generally those where an individual or group of individuals works with a specialist developer to help deliver homes. The developer may identify a plot of land, manage construction and provide financial assistance.
