For English Heritage, 2014: eftec undertook this research to generate economic valuation evidence for the heritage benefits provided by two English Heritage sites by using the total economic value approach. A stated preference method (i.e. contingent valuation) was used to determine English Heritage site visitors’ willingness to pay for English Heritage sites. The results were also used to create a ‘value transfer equation’ so that the results can be used in value transfer exercises.
