B Corp brief - UK & Europe - September 2026

New B Corps with something to sell.

24 companies on Honch's list certified as B Corps in late summer 2026. Most are small: a restaurant, a farm, a three-person installer. This brief picks out the eight with the size, the growth and the buying power to be worth a sales call, and says how to approach each one.

What is happening

B Corp is changing. On 2 September B Lab UK named the first 18 UK companies certified under its new standards, including Mulberry, Huel and Pip & Nut. The new rules drop the single 80-point score in favour of minimum requirements across seven impact topics, checked by third-party auditors. Almost everyone on this list still carries a points score, which means they submitted under the old rules before the deadline at the end of 2025 and have only now come through verification.

The interesting companies here are not the ones with the highest scores. They are mid-sized firms that sell through tenders, frameworks and professional referrals, where social value is scored and ESG questions are now common on supplier forms. For an accountant, a facilities supplier or a Microsoft partner, B Corp is a sales tool. Most of them pair it with something else: an acquisition, a new region, a merger or new funding.

Why they are worth a call
01
They have just finished a project Certification takes many months of evidence gathering. Once it is through, the sustainability lead and leadership team have time again, and a story they want to tell clients.
02
They are about to market it New B Corps update bids, pitch decks and websites to use the badge. That is a natural moment for anyone selling marketing, new-business data or bid support.
03
They look at their suppliers The assessment asks how a company buys. Suppliers who can show their own standards tend to get a better hearing from a newly certified buyer.

04

Also worth a look

Smaller or less-profiled B Corps from the same list, each with a reason to keep an eye on them.

How this list was built
B Impact scores and certification months come from the B Lab directory where a listing could be found. Six companies show an August date there; they are kept because they appeared in Honch's September list. Four could not be found in the directory: Personio and Cleanevent have announced their certification publicly, Laurence Associates has posted about it on its website, and Aston & James is unconfirmed. Staff numbers are from Honch. Cia. Hering was removed: it has been a certified B Corp since 2021, so September is most likely a recertification.
