Write, call or email — we aim to reply within two working days. World Aid Network is a UK Muslim charity based at International House, 51 Borough High Street, London SE1 1NB. You can reach us on +44 20 4622 0003 or at info@worldaidnetwork.org. We are committed to transparency: if you have any question about how your Zakat is handled, verified or delivered, ask us directly. ## What we can help with - Questions about Zakat calculation or eligibility - Queries about how donations are used and our [100% donation policy](https://www.zakat-calculator.org.uk/100-percent-policy) - Gift Aid questions for UK taxpayers - Partnership or corporate Zakat enquiries - Media and press enquiries ## Complex Zakat questions welcome Many Zakat questions have no one-line answer — and those are exactly the ones worth asking. Common examples we hear from UK Muslims include: - Business stock: how to value trading inventory and work-in-progress for Zakat — see our guide to [Zakat on business assets](https://www.zakat-calculator.org.uk/zakat-on-business) - Pensions: whether workplace and personal pensions are Zakatable, and when — see [Zakat on pensions](https://www.zakat-calculator.org.uk/zakat-on-pension) - Inheritance: Zakat on inherited wealth you have received or are still owed — see [Zakat on inheritance](https://www.zakat-calculator.org.uk/zakat-on-inheritance) We can explain how the mainstream principles apply and point you to the right guides. For binding personal rulings on your own circumstances, we always recommend consulting a qualified scholar. ## Response times We aim to respond to all enquiries within 2 working days. For urgent queries related to an existing donation, please include your donation reference number so we can trace it quickly. The same team also answers through [contact on worldaidnetwork.org](https://worldaidnetwork.org/contact). ## Before you write — quick answers Many common questions are already answered on this site.
