That usually means the assessment was incomplete — here the assessor recorded no heating system at all. The costs below are real; a fresh assessment would be the way to find the gain.
| Measure | Grant | Net cost | Saving / yr | Payback | Grade effect |
|---|---|---|---|---|---|
| Change of heating system | — | £3,000 – £7,000 | — | — | — |
| Double glazing | — | £2,500 – £6,500 | — | — | — |
| Solar water heating | — | £4,000 – £6,000 | — | — | — |
| Solid wall insulation | — | £5,500 – £14,500 | — | — | — |
| Solar photovoltaic panels | — | £11,000 – £20,000 | — | — | — |

Schools from the DfE register, performance from the KS4 performance tables. Progress 8 is a GCSE measure, so primaries have none. Distance is straight-line from the postcode, not a catchment: admission is decided by the school, not by us.
Area context
Police-recorded crime for the wider neighbourhood, not this address. We grade homes, never neighbourhoods — so this is reported as a count, not a rating.
