Changes to building regulations come into effect this month, but what about planning permissions for new conservatories? Does your new conservatory need it? Or is it possible to avoid it?… Allow us to explain.
If any of the following points apply to your new conservatory (or single-storey extension), it’s likely it will require planning permission to go ahead:
*These rules only apply to detached and semi-detached houses in England.
With regards to building regulations, unless the floor space exceeds 30 square metres, it is separated from the house by walls, doors, or windows, and is built at ground level, all new conservatories will require building regulations.**
**Correct at time of publishing.

If your new conservatory project requires planning permission, we’ve created this handy checklist to ensure your new conservatory meets the correct requirements:
☐ Pre-submission form
Obtained from your local council Planning Department, completing a pre-submission form will confirm the need for planning permission and prepare you for any potential pitfalls along the way.
planning@wolverhampton.gov.uk offers pre-application advice.
☐ Planning application form
Apply for planning permission with the City of Wolverhampton Council
☐ Plans and drawings
☐ Certificate of Ownership
☐ Ordnance Survey
☐ Agricultural Holdings Certificate
☐ Design and Access Statement (conservation areas)
☐ Fees
Calculate your planning fee
☐ Amended designs
If the planning application is rejected at the first submission, you can resubmit it within 12 months at no extra cost.
☐ Building insurance
Check your building insurance covers your new project.
☐ Contents insurance
As above.
☐ Party Wall Agreement

If your new conservatory affects neighbouring properties, you may need to put a Party Wall agreement in place. Terraced and semi-detached homes often require them.
