The United Kingdom is a post-Brexit standalone Shopping market with CSS available. Your spend and saving are in pounds, and feed uploads use the GB country code.
Great Britain is outside the EU customs union and VAT area
Since Brexit, goods moving between the EU and Great Britain clear customs, and VAT on consumer sales follows UK rules rather than EU ones.
The rules and thresholds have changed more than once. Confirm the current position with your accountant before launch, not after the first shipment.
Pounds, and a price list that moves
The pound floats against the euro. A euro catalogue converted once will drift, and on a market this size the drift is not small.
Set a re-pricing cadence rather than a conversion.
English is shared, and Ireland is still a different market
The words transfer to Ireland unchanged. The currency, the VAT treatment and the customs position do not, because Ireland is inside the EU.
Run them as two markets that happen to share a language.
The shop systems here, and how they reach Merchant Center
In the UK, Wix Stores, Shopify and WooCommerce are the three most common shop systems on .uk-domain sites, based on BuiltWith-sourced data reported by Statista (August 2026), with Wix Stores used on roughly a quarter of tracked sites, followed by Shopify and then WooCommerce. If you run your shop on Wix Stores or Shopify, your product feed connects to Google Merchant Center through each platform's built-in Google integration. If you run on WooCommerce, the official Google for WooCommerce plugin syncs your product data to Merchant Center automatically.
Frequently asked
Is the United Kingdom in the EU?
No. Customs and VAT follow UK rules for goods arriving from the EU.
Which currency do I price in?
Pounds sterling, which floats against the euro.
Can I use the same feed in Ireland?
The language, yes. The currency, VAT and customs, no.
How big is the UK market?
Around 69 million people, one of the two largest on this list, and among the most developed online retail markets anywhere.
Is the customs work worth it?
That is a question about your margins and your logistics, not about advertising. Get the shipping and VAT position settled first, then advertise.
Does switching CSS mean changing my product feed?
No. The switch only changes which authorised CSS submits the ad that Merchant Center already builds from your feed. However your catalogue reaches Merchant Center today, it keeps reaching it exactly the same way.
Is there a setup fee or a minimum contract?
No setup fee, and no lock-in: cancel from your portal whenever you like. You also have 60 days after going live to change your mind for a full refund, no questions asked.
Do you build a custom feed, or use what I already have?
We use the feed you already send to Merchant Center. There is nothing new to build, and no separate export just for us.
Does the switch pause my ads while Google processes it?
No. Your ads keep running the entire time, under whichever CSS is currently submitting them, until the new one is confirmed. There is no gap in coverage.
Is there a limit on how many shops I can add?
No. Pricing is per shop with an automatic volume discount from five shops, calculated from your total. Adding more shops later just recalculates that total; it does not require a new agreement.
Who do I actually talk to if something needs fixing?
A real person on our side, not an anonymous ticket queue. Support, billing and cancellation are all handled from the same portal you use to add a shop.
Is my data shared with anyone new by switching?
No. A CSS only submits the ad your Merchant Center feed already builds; it does not see your website, your customers or any data beyond what Merchant Center already exposes to any authorised party.
Does this work if I already run Performance Max, not just standard Shopping?
Yes. The bid-power effect applies to the Shopping portion of a PMax campaign specifically; the rest of the campaign runs exactly as before, because the switch happens in Merchant Center, not inside the campaign itself.
