TL;DR: do UK online shops have to include delivery in the price?
Yes, if delivery is mandatory. On 2 November 2026 the UK Competition and Markets Authority (CMA) sent an open letter to online retailers, marketplaces, comparison sites and search engines ahead of Christmas. Its message: “The first price consumers see should be the price they pay.” Under the DMCC Act, the total price, including the cheapest mandatory delivery charge, must appear in ads, on product pages, in the basket and at checkout. The CMA lists four delivery-fee practices it is watching for and can fine up to 10% of global turnover or £300,000, whichever is greater. If you sell to UK shoppers, check your shop before Black Friday on 27 November.
