How to use these figures

Northern Ireland has different policy and grant arrangements from Great Britain, so scheme-specific calculator assumptions should be checked carefully.

Start with the table to understand project scale, then use a calculator to add floor area, condition, finish level and other project-specific inputs. A postcode-aware calculator can infer the same broad region while still allowing a manual override.
