What the regional adjustment changes
What can change a real Nottingham quote?
- Velux, dormer, hip-to-gable, mansard or shell-only type
- Usable new floor area
- Roof structure and existing head height
- New staircase position and specification
- Structural steel and roof alterations
- Ensuite, electrics, heating and finish level
- Region, access and scaffolding
Local planning considerations
Use the regional model as an early budget only; property condition, access and contractor availability can have a larger effect than the regional multiplier.
- Existing property condition can move refurbishment costs more than the modest East Midlands model adjustment.
- Groundworks, drainage and level changes should be kept separate on extensions, driveways and landscaping projects.
- For older homes, allow surveys or opening-up work before treating an online estimate as a firm scope.
How the regional model works
The 0.97× factor places this planning estimate 3% below the national planning baseline. We keep that modelling assumption separate from the dated national benchmark so users can see exactly which part comes from an external source and which part is UK Home Costs modelling.

Frequently asked questions
How much does a loft conversion cost in Nottingham in 2026?
Our modelled Nottingham ranges run from about £21,850–£29,100 for a 30m² Velux or rooflight conversion to about £48,500–£77,600 for a 30m² mansard, using current national type benchmarks and the East Midlands regional factor.
How much is a dormer loft conversion in Nottingham?
The modelled Nottingham planning range for a typical 30m² dormer is about £38,800–£58,200. It starts from the current national £40,000–£60,000 benchmark and applies the East Midlands factor.
Why is the Nottingham estimate different from the UK benchmark?
UK Home Costs applies a 0.97× East Midlands planning factor, which places the model 3% below the national planning baseline. The factor is a transparent modelling assumption and not an observed city-wide contractor price index.
What can push a loft conversion above the modelled range?
Staircase changes, structural steel, low head height, complex roof alterations, an ensuite, premium finishes, difficult access and fire-safety work can all increase the final quote.
