Gift Aid Declaration

Gift Aid costs you nothing, but enables us to reclaim tax you have already paid to the Government. The additional funds help in our work to visit, document and protect our national underground heritage.


By selecting 'Yes' above you are confirming that

  1. you are a UK taxpayer
  2. the amount of Income Tax and/or Capital Gains Tax you pay in each tax year is at least as much as all charities and CASCs will reclaim on your donations (Council Tax and VAT do not count) and
  3. we may continue to reclaim 25p of tax for each £1 that you give us until you tell us to stop.

About Gift Aid

Gift Aid increases the value of donations to charities by allowing them to reclaim basic rate tax on your gift. We would like to reclaim gift aid on your behalf. We can only reclaim Gift Aid if you are a UK taxpayer. Please confirm that you are a eligible for gift aid above. More about Gift Aid.
