It follows a profits warning from Stonegate, which owns 450 sites across the capital.
Among the many pubs run by Stonegate are much-loved names like The White Swan in Richmond and Royal Oak in Teddington.
They also own the Yates and Slug and Lettuce brands.
The firm’s struggling to refinance over £2 billion of debt and had said before there was no guarantee it could keep going.
Stonegate’s owners TDR have reassured MPs the pub chain does have a future.
Stonegate’s told us TDR continues to be a supportive investor and the their pubs are becoming more profitable.
But the GMB Union says there are still more questions to answer.
A spokesperson for Stonegate says:
“We are really pleased with the performance of the business in 2023, which included a sector leading Christmas reading period. We have delivered a rise in revenue and a significant increase in profitability. We have been very clear that we continue to work towards achieving our long-term balance sheet goals, with the successful refinancing of a portion of our estate in December making a significant strategic step towards this. We would also like to assure our employees and partners that no venues are at risk as a result of this process. TDR Capital has been and continues to be a supportive investor in Stonegate developing the business over the last fourteen years into the UK’s largest pub company with 4,500 great venues across the country,”
