Hidden costs beyond any ecommerce platform plan in England: ICO fee, VAT, refunds and surcharge rules

Costs that sit outside every plan price

A platform plan is one budget line. Several UK rules create other costs or cap what a shop may charge, and they apply whichever platform runs the store. Plan prices sit in the platform costs and budget guide. The lines below come on top.

These are UK-wide rules, so they apply to a shop in England. They do not change with the platform. What changes is how much work each platform leaves to you, which the comparison of Shopify and WooCommerce explores for technical tasks.

The ICO data protection fee

Organisations, including sole traders, that use personal information need to pay a data protection fee unless exempt, under the Data Protection (Charges and Information) Regulations 2018. Many controllers can rely on an exemption. The fee must be renewed each year.

The ICO fee guide sets three tiers. Tier 1 is £52 for a maximum financial-year turnover of £632,000 or no more than 10 members of staff. Tier 2 is £78 for a maximum turnover of £36 million or no more than 250 staff. Tier 3 is £3,763 for everyone else.

Direct debit gives an automatic £5 discount. No VAT is charged on the fee, because statutory fees are outside the scope of VAT. A fine of up to £4,350 may be issued if the fee is not paid or the organisation fails to report that it no longer needs to pay.

Refunds, cancellations and return costs

The Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 came into force on 13 June 2014. A customer can cancel an online order up to 14 days after delivery without giving a reason.

If the customer is not told about the right to cancel, they can cancel at any time in the next 12 months. Under regulation 34, the trader must reimburse delivery payments unless the consumer expressly chose delivery costing more than the least expensive common and generally acceptable option.

In that case, reimbursement covers delivery up to the cost of that cheaper option.

For a sales contract where the trader has not offered to collect, reimbursement is due by the end of 14 days after the goods come back or, if earlier, the customer supplies evidence of sending them. Online sellers can withhold refunds until goods or evidence of return arrive. Reimbursement uses the original means of payment, with no fee.

The consumer must bear the direct cost of returning goods unless an exception applies. A refund need not include return delivery unless the trader offered to bear it or did not tell the customer they would have to pay. Free returns are therefore a commercial choice that adds cost.

Card surcharges and total-price rules

Businesses cannot impose surcharges for paying by a consumer debit or credit card or an electronic payment service. The ban does not apply to commercial cards. It applies whether or not the payment relates to a contract.

For other methods, surcharges to consumers are governed by the Consumer Rights (Payment Surcharges) Regulations 2012, amended by the Payment Services Regulations 2017. A surcharge must not exceed the business's cost of processing that method. That limit covers business-to-consumer contracts, not business-to-business ones.

Delivery, booking or administrative fees are allowed if they are the same whatever the payment method. Card processing fees cannot be passed to consumers as card surcharges, so they stay in your margin. Processors publish their own fee pages. The payment gateway integrations comparison shows which gateways each platform supports.

Under Part 4, Chapter 1 of the Digital Markets, Competition and Consumers Act 2024, businesses must not mislead consumers or hide or omit information needed for an informed decision. Details of any payment surcharge should generally appear up front beside the main price. Unusual surcharges need special attention before the customer starts an order.

Drip pricing and misleading countdown timers are banned under the new regime. Failing to include mandatory charges upfront, adding unavoidable fees at checkout and headline prices that exclude compulsory costs have been unlawful for years under the Consumer Protection from Unfair Trading Regulations 2008. Early enforcement was expected to focus on fees hidden until late in the purchase process.

A product price must include non-optional surcharges wherever it appears, before the customer takes any step towards buying. Before an order, the seller must give the price including all taxes, plus delivery arrangements, costs and arrival time. The total price, including delivery or other charges, must be clear and prominent directly before the order.

VAT on sales, services and imports

Register for VAT if taxable turnover for the last 12 months goes over £90,000, or you expect it to go over £90,000 in the next 30 days. Taxable turnover is everything sold that is not VAT exempt or out of scope.

It includes zero-rated, reduced-rated and standard-rated goods, plus overseas services you had to reverse charge. After going over the threshold, register within 30 days of the end of that month. The effective date is the first day of the second month after. The standard rate is 20 per cent on most goods and services.

Platform and app fees can matter here. The reverse charge applies where a UK business receives business-to-business general-rule services from a supplier outside the UK, unless use-and-enjoyment provisions apply. An unregistered UK business adds reverse-charge services to taxable turnover when deciding whether to register. Ask each platform and app vendor which entity invoices you, and where it belongs.

Importing goods into England, Wales or Scotland needs an EORI number starting with GB. In Great Britain, Customs Duty is payable on excise goods of any value. A VAT-registered business can claim back VAT paid on imported goods, so treat that amount as cash flow rather than a permanent cost.

Comparing platforms against these costs

The rules are fixed, but platforms differ in how much of the compliance work they automate. Run the same tests on each shortlisted platform, for example Shopify, WooCommerce or BigCommerce, during a demo or trial.

A platform that fails a test is not ruled out. The failure becomes a labour or app cost to add to its total. Place each duty in the store journey with the UK regulations rule map.

Example: turning the rules into a cost sheet

The figures here use only the ICO amounts above. A tier 1 shop paying by direct debit pays £52 minus £5, which is £47. A tier 2 shop pays £78 minus £5, which is £73. Add the other lines as separate rows, then score each platform against them.

Carry these tests into your platform selection checklist. Then set plan fees beside them using the platform pricing models comparison, so each platform carries its full cost.
