Yes, if you are a UK taxpayer. 

Adding Gift Aid to your donation increases the value of your gift at no extra cost to you and is a great way to support parks. This means that if you donate £10, your donation could become £12.50 when Gift Aid is added. And remember, the Heritage Fund matching grant would double this, so your £10 donation with Gift Aid would become a £25 investment in Scotland’s parks. 

For your donation to qualify for Gift Aid, you must be a registered UK tax payer, have paid the same amount or more in Income Tax or Capital Gains Tax in that tax year, and provide personal details for a Gift Aid declaration.
