Most planning applications are supposed to be decided within eight to 13 weeks depending on complexity.
However, the report shows some authorities are far more likely to miss that deadline than others.
Nottingham recorded the lowest rate of on-time decisions, with just 62% of applications processed within the target timeframe. Rochford in Essex followed with 73%, while the New Forest National Park Authority delivered 75% of decisions on time.
By contrast, 26 local authorities achieved a perfect record for timely decisions, including Stockport, Wokingham, Chichester and Southend-on-Sea.
When it comes to the overall regions, homeowners in London, on average, may be facing tougher odds when it comes to getting planning permission approved, despite submitting some of the highest volumes of applications in the country.
London recorded the second-highest number of approved householder planning applications in 2025, with 16,535 granted. However, when measured by success rate, the capital ranked as the worst-performing region, with just 85% of applications granted.
Meanwhile, homeowners in the North East enjoyed the best chances of success. The region posted the highest approval rate in the UK at 95%, giving applicants the strongest odds of securing planning permission.
Overall, the South East emerged as the UK’s home improvement hotspot, approving more than 23,000 applications, the highest total of any region.
| Region | Total decisions (all) | Total granted (all) | % Granted |
| South East | 25,846 | 23,397 | 91% |

With the South East leading the country for most planning applications, Buckinghamshire emerged as the UK’s most active local authority for home improvements, granting 2,234 permissions in 2025, more than any other area.
With average house prices around £490,000, according to Rightmove, many homeowners appear to be opting to renovate rather than move amid affordability pressures in the housing market.
Birmingham ranked second, approving 1,654 applications, despite receiving more than 500 fewer submissions overall, suggesting a comparatively strong success rate.
Leeds followed closely in third place with 1,651 approvals in the Yorkshire and Humber region, just three fewer than Birmingham.
North Yorkshire and Wiltshire rounded out the top five, with 1,640 and 1,414 approvals, respectively, highlighting strong demand for home improvement projects across both urban and rural areas of England.
Two areas in the North East granted zero applications last year: both Hartlepool Development Corporation and Middlesbrough Development Corporation didn’t approve any planning applications, while the City of London approved one.
