The Weston family is worth an estimated £18.939 billion, according to the 2026 Sunday Times Rich List, which ranks Guy, George, Alannah and Galen Weston and family fifth in the UK. That fortune is now back in the headlines: the Canadian side of the family is reported to be in advanced talks to buy Boots for around £7 billion (about US$9bn). As of 6 October 2026, the reports do not establish a signed agreement. Here is where the money behind the Weston name actually sits, and what the reported deal does and does not tell you about it.
How much is the Weston family worth in 2026?
The figure most often quoted in Britain is the one compiled by the Sunday Times Rich List 2026, published in May 2026. It values the family at £18.939bn, up from £17.746bn a year earlier, and moves them from sixth to fifth place.
This is a family valuation, not one person's bank balance: the entry groups several relatives across two countries. It is also an estimate. The compilers work from shareholdings, company accounts and known deals, so the true number could sit either side of the headline, and it moves with the share price of the companies the family controls.

Where the Weston money comes from
The fortune started with a bakery. George Weston opened one in Toronto in 1884, and his son Garfield Weston expanded the business into Britain in the 20th century. Over the following decades it split into two branches, one British and one Canadian, which still operate as separate empires under the same family name.
The British side: Primark and Associated British Foods
In the UK, the family's main asset is a majority stake in Associated British Foods (ABF), the FTSE 100 group behind Primark. ABF also owns grocery brands such as Twinings, Ovaltine and Ryvita, plus British Sugar. The holding sits in Wittington Investments Ltd, a private company that is in turn largely owned by the Garfield Weston Foundation, one of Britain's biggest grant-making charities. Outside ABF, the family also owns Fortnum & Mason.
The charity link matters when you read the headline number. The Garfield Weston Foundation controls 79.2% of the UK's Wittington Investments, and charitable ownership is not the same thing as money personally available to family members.
The Canadian side: Loblaw and Shoppers Drug Mart
In Canada, the family controls George Weston Ltd, which in turn controls Loblaw, the country's largest food retailer and the owner of the Shoppers Drug Mart pharmacy chain. So the Canadian branch already runs a large pharmacy business. The Canadian branch is also the one that owned Selfridges, alongside Brown Thomas and Arnotts in Ireland, before agreeing to sell the department store group for around £4bn to Thailand's Central Group and Austria's Signa in late 2021.
The Boots deal: what has actually been reported
The talks were first reported by the Wall Street Journal on 30 September 2026 and picked up by Reuters and the Press Association. According to those reports, the Canadian branch is negotiating through Wittington Investments, a Weston holding company that shares its name with the UK one. It is in advanced talks with Sycamore Partners, the US private equity firm that owns Boots, and reports published on 1 October said a deal could be reached over the following week. Both Boots and Sycamore have declined to comment.
Here is the background, as reported by City AM and Pharmacy Business:
- Sycamore bought Walgreens Boots Alliance for $23.7bn in 2025, then split it into separate businesses, with Boots becoming a standalone UK-based company.
- The Boots business includes Boots UK and Ireland, Boots Opticians, No7 Beauty Company and pharmacies in Thailand, Mexico and Germany. It has around 1,800 UK stores and roughly 51,000 staff.
- An earlier attempt to sell to Australia's Sigma Healthcare fell through in the summer, and talks with the Westons stalled after Sycamore rejected a reduced offer.
- A London stock market listing was also considered. A completed sale to the Westons would make that listing unnecessary.
Until the parties confirm terms, treat the £7bn figure as a reported price, not a done deal. Canadian pharmacy title Pharmasist pointed out on 3 October that the reporting does not establish a signed agreement.
Can the Westons afford £7 billion?
On paper, the reported price equals more than a third of the family's estimated Rich List fortune, although that fortune covers both branches while the bid comes from the Canadian side alone. In practice, takeovers of this size are rarely paid out of personal wealth. A holding company like Wittington can combine its own cash with borrowing, and the reported valuation of Boots includes debt. The financing structure has not been published, so any claim about how much the family would put in itself is guesswork.
What the deal would signal is clearer. It would mark a return to British retail for the Canadian branch, four years after the Selfridges sale, and put the country's best-known chemist under the same family name as Primark, even though the two businesses would sit in different branches of the empire.
Weston family net worth: the bottom line
The Weston family's estimated £18.939bn fortune rests on two separate retail and food empires: ABF and Primark in Britain, George Weston and Loblaw in Canada. If the Boots talks end in a signed deal, the family's British high-street footprint grows again. If they collapse, as they nearly did this summer, the family's estimated wealth will still move with the value of its holdings, whatever happens to Boots.
