You can ‘Give As You Earn’ to Kidney Research through your employer. Download and complete the donor instruction form and take it to your payroll department. Tell them that you want to contribute to charity through the Give As You Earn scheme. If they do not have this scheme available ask them to set it up. The amount you donate will be deducted from your pre-tax salary, and every £1 donated to the charity will cost you 60p to 78p (depending on your marginal tax rate).
The South West Thames Kidney Fund’s charity registration number is 800952.
