Sefton includes Southport, Bootle, and Crosby. About 46.7% of the borough is Green Belt, shaping urban edges and protecting surrounding countryside. Known for coastal towns, historic streets, and rural villages, planning balances residential, commercial, and conversion projects with landscape protection.
In the last year Sefton decided 1,033 applications which is just above the national average of 959. The approval rate was 93% (marginally above the national average of 88%) and 56% of applications were decided on time, (on par with the national average of 58%).

"We love helping clients win Planning Permission in Sefton"
Housing Supply in Sefton
Sefton currently reports a five-year housing land supply of 3.3 years (updated June 2026). This is significantly below the national requirement. Compared with other authorities in the North West, Sefton has a weak housing land supply position.
Conservation and Listed Buildings
Sefton has a varied historic environment, with several Conservation Areas and a number of listed buildings across its coastal and suburban settlements. Heritage constraints are particularly evident within the Lord Street Conservation Area and Waterloo Park Conservation Area, where formal townscape, Victorian resort architecture, and historic public realm define local character.
One of the top reasons heritage building applications are refused is causing harm to historic significance, a risk that can arise when proposals are not prepared by a consultant with heritage expertise. We help minimise this risk with expert, site-specific guidance; contact us here.
Green Belt Approvals in Sefton
46.7% of Sefton is within the Green Belt and proposals in these areas can be subject to high levels of scrutiny.
The Green Belt around Formby, Ainsdale, and Maghull restricts development to protect countryside and prevent urban sprawl.
In our experience, one of the top reasons poorly conceived Green Belt proposals are refused is causing 'harm to openness'. We can lower the risk of refusal with site-specific guidance. Contact us here.
You can also check whether your land is within the Green Belt using our interactive Green Belt map.
Flood Risk in Sefton
Coastal dune systems and the low-lying Southport coastal plain face significant tidal and surface water flood risk, with Flood Zone 3 a key constraint on development in the northern part of the borough.
Where constraints permit, we can develop proposals that manage flood risk thoughtfully to give applications the best chance of approval. Learn more about development risks in flood risk areas here.
