Your best bet is probably to join up to the Blue Light Card scheme or the like. Blue Light Card provides those in the NHS, emergency services, the social care sector and armed forces with discounts online and in-store. Alternatively, you could look online for some Tiguan listings that you're interested in and contact the dealer/seller directly about discounts as they vary from retailer to retailer and often aren't well-advertised on-site. Various retail groups (like Glyn Hopkins) offer prominent discounts, but then you're tied into the models that they have on offer. In my opinion, it's better to find some Tiguans that you'd like to enquire about and then ask directly about discounts for healthcare and NHS workers.

Good luck finding you Tiguan Allspace and take care.
