Your policy price can be broken down into 3 parts:
Insurance Premium Tax (IPT): IPT is a tax on general insurance premiums. Currently the standard rate is 12%.
Distribution Fee: All payments are handled by Stripe, who charge a percentage-based fee for each credit or debit card payment. Currently, the charge is 1.4% + 20p for major European cards.
Insurance Premium: After substituting the above, the remaining price is representative of your insurance premium.
