VQOTW: VAT CHANGE OF RATE AND IMPACT ON VOUCHERS

My client operates a luxury hotel in the UK. They have recently reopened and will now recommence selling face value gift vouchers. The holder can redeem their vouchers against room reservations, dining at the restaurant/bar and when using the leisure and spa facilities. The restaurant does not offer a takeaway service. Historically the client has always charged VAT at the standard rate on all their supplies. Could you please clarify the impact of the temporary rate change on the issue of face value vouchers. When will the VAT be due and at which rate?
