The TikTok Shop UK news that matters this November: eligible shops are being enrolled in a new GMV Max programme by default, Subscribe & Save is now in Seller Centre, and online sales are still growing going into peak. Here is what changed, what to check in your shop and one routine to get right before Black Friday.
GMV Max Net Sales Boost: eligible shops are enrolled by default
TikTok Shop's UK Seller University update of 12 October introduced GMV Max Net Sales Boost, a programme that creates and runs ads for eligible products you are not already advertising. Eligible shops are enrolled by default unless they opt out.
The first 30 days carry no extra cost and the settings are locked. After that, standard fees apply and you can change the ROI target or switch the programme off. Opting out during the first 30 days goes through your Account Manager or TikTok's opt-out form, and requests can take up to seven working days. The update gives no eligibility criteria and no fee amounts, so check Seller Centre and your inbox for your own shop's status.
What to do now:
- Check in Seller Centre, or with your Account Manager, whether your shop is enrolled.
- Work out the margin on each product the programme can advertise, so you know what ROI target to set after day 30.
- Decide before day 30 whether you want it running alongside your own GMV Max campaigns.
We go through the checks in more detail in GMV Max Net Sales Boost: what UK sellers should check, and our TikTok Shop ads page explains how we run GMV Max and Spark Ads behind content that has already sold.
Subscribe & Save is now in Seller Centre
The same update added Subscribe & Save. Customers can buy a product on a repeat order and you choose a subscription discount of 5%, 10%, 15% or 20%, set up under Manage Products. It suits products people reorder on a cycle, such as supplements, pet food, coffee and household refills. Check the discount against your margin, alongside your other promotions, before you switch it on.

The number: online sales up 8.9% on a year earlier
Online retail sales values in Great Britain were 8.9% higher in August 2026 than in August 2025, according to the ONS retail sales bulletin published on 18 September 2026. Demand online is still growing into peak, so plan Black Friday stock from this year's sales rather than last year's, and check how many weeks of cover you have now.
One thing to try: keep stock and samples going through Black Friday
When a best seller runs out, its product link stops working on every creator video that was selling it. This is the routine we run with brands before peak:
- Every Monday, work out weeks of cover for each hero product (stock divided by weekly sales) against your reorder lead time. Act when it falls under four weeks.
- Before Black Friday, set aside a share of units for the push (for example 30%) and decide how many samples you can afford.
- Under two weeks of cover, slow sampling and give creators another product to film.
- If it sells out, pause sampling and ads on it and tell creators when it is back. Within seven days of the restock, message everyone who posted it.
