Frequently asked questions

Do you need planning permission to demolish a building?
Most demolition outside conservation areas is permitted development under Part 11 of the GPDO, but you must submit a prior-approval application covering method and restoration. Demolition of dwellinghouses always needs prior approval, even where permitted development applies.
What is a 'replacement dwelling' application?
Planning permission to demolish an existing dwelling and replace it with a new one. The principle is not automatic: councils assess the replacement against local policy on impact, scale, design and any heritage or rural-character considerations.
Can I get email alerts for new demolition applications in Sefton?
Yes. Click "Set up alerts" on this page and you'll get a daily or weekly email listing every new demolition application published by Sefton. You can also narrow the alert to a postcode, street, or drawn area.

We check Sefton's planning portal daily. New demolition applications appear here within a day of being published.
