Valuation
Outcome
Valuation
Household spending on home improvements; Average house price impact aggregated across number of affected properties
Description of financial proxy
This valuation details the household spending on home improvements compared with the average house price impact aggregated across number of affected properties due to an additional runway being built at Heathrow airport.
Context
This was used by nef (new economics foundation) as part of the evaluation of the potential impacts on local communities of an additional runway at Heathrow airport.
Valuation Technique
Cost or income
Value
In 2009, average spending on DIY and home improvements per household per week in the UK is �20.50; For house prices value calculated according to formula for valuing noise disturbance: (Noise Depreciation Index) x (decibel change in noise) x (property price) x (number of properties). For UK, Noise Depreciation Index recommended as 0.68 per cent

Relevant Information
Analysis suggests that loss of well-being as a result of disturbance from different sources, including noise and air pollution, are of a comparable order of magnitude. Generalised blight from living with uncertainty and loss of community fabric may be just as disturbing for local residents as other impacts.
