Greggs was hit by a major IT outage today as customers reported the bakery chain’s stores were shut across Britain due to a technical issue with card payments.
Hungry commuters reported closures in cities such as Cardiff, London, Manchester and Newcastle this morning – while other outlets were open but only accepting cash.
Some bemoaned the lack of a morning coffee, while there were also reports of staff baking inside stores which had temporarily ‘closed’ signs placed outside.
Greggs told today: ‘We are currently experiencing issues accepting payments in our shops. We are working to resolve this as soon as possible.’
It is the latest IT outage to affect a major chain in recent days after technical issues affected Sainsbury’s and Tesco on Saturday and McDonald’s last Friday.

A customer said: ‘Hey, why are all the Greggs stores shut in Cardiff with temporarily closed signs on, but staff are inside baking? What time will they be open today?’
Another tweeted: ‘Why are all of the stores in Newcastle city centre closed?’ And a third added: ‘Greggs closed in Manchester, this could cause a riot.’
A fourth posted: ‘Greggs in Westminster closed. Problem with tills. Is this Nationwide or just local?’ And another said: ‘Greggs all closed due to technology issues.’
Other tweets included ‘all my local Greggs stores are closed because of technical issues, missing my morning coffee’ and ‘Tills down Greggs, awful start to the day.’
And someone else posted: ‘Greggs this morning cash only! Sitting here with my coffee watching almost everyone have to walk out.’
It comes after McDonald’s, Sainsbury’s and Tesco lost millions of pounds over the past week amid technical issues.
Tesco and Sainsbury’s were both hit with unrelated problems on Saturday which saw them both apologise to angry customers who were left without orders.
And that came one day after McDonald’s also said sorry to customers last Friday after they were unable to order food due to an IT system outage in its restaurants.
Sainsbury’s shoppers could not make contactless payments following an overnight software update and the firm could not fulfil the ‘vast majority’ of online deliveries.
Meanwhile, Tesco had to cancel some online orders due for delivery on Saturday – although it is understood that only a small proportion of these were impacted.
Retail experts warned that the IT issues highlighted ‘the fragility of growing dependence on digital infrastructure’ amid concerns more firms could be hit.
While a total figure has not been given on the cost of the outages, the Telegraph estimated that Sainsbury’s orders worth up to £9million could have been affected.
Earlier this week, before the Greggs technical issue, retail experts said the problems showed ‘even large corporations aren’t immune from normal IT troubles’.
Retail expert Richard Hammond, chief executive and co-founder of analytics firm Uncrowd, told : ‘Complex modern tech stacks are by their distributed nature rife with vulnerabilities.
‘We don’t know what this exact cause was but just one small part of the complex chain of dependencies can change one thing and that has unexpected consequences, including shutting down whole customer systems.
‘Retailers can’t even foresee that, they just can’t. What’s important is to have a disaster process in place for the inevitable, and be ready to be humble and gracious in rebuilding customer trust.’
Richard Lim, chief executive of consultancy Retail Economics, told The Times: ‘While the immediate consequences of wasted food, lost revenue, and a potential erosion of customer trust are a blow to the retailer, the situation highlights a larger concern around operational resilience.
‘This incident underscores the fragility of growing dependence on digital infrastructure and the critical nature of investing in robust IT solutions.
‘Digital disruption is a principal risk for most retailers, but ensuring contingency planning is in place is vital.’
Retail technology analyst Miya Knights told BBC Radio 4 that any major update to a live system would require ‘rigorous testing protocols’ and ‘rigorous release planning’.
She added: ‘At the end of the day it’s a human-related problem that these things have come down to the point where they are affecting customers.’
Guy Warren, chief executive of software company ITRS, told technology website Verdict that the three outages showed IT estates are growing more susceptible to outages with longer periods of downtime.

He said: ‘With operational resilience at the forefront of the business agenda, firms should already have introduced highly proactive monitoring and security capabilities, so they see what their systems are doing in real-time.
‘If these three companies had access to this level of insight, the outages across their platforms might never have happened – let alone drag on until it becomes headline news.’
And Chelsea Hopkins, PR manager at internet service provider Fasthosts, also told Verdict that the amount of sales lost will have been ‘staggering’.
She added: ‘When outages like this occur the first thought for many is a cyber attack, but this is a reminder that even large corporations aren’t immune from normal IT troubles.’
James Bore, who runs the Bores technology and security consultancy, often deals with situations relating to supply chains, logistics and overall societal security.
He told : ‘There’s a rule in technology- never deploy on a Friday. The technology involved in these systems has only grown more fragile and complex over the years, and there is rarely an incentive to reduce the complexity or rebuild them properly from the ground up.

A Sainsbury’s in Wandsworth, South West London, said that tills were ‘cash only’ on Saturday
‘At this scale and complexity thorough testing is essential, as even the slightest mistake can have unpredictable consequences – as we’ve seen.

‘This is a fundamental risk of centralised control of systems by large companies – when these systems are not centralised any failures are local and so impacts are limited. Despite the impact of these, it could have easily been much worse.’
He also warned of the dangers of relying too much on cashless payment methods.
Mr Bore explained: ‘Moving to a cashless society means moving to a single system to manage all payments.
‘Ignoring issues around privacy and control, any failures in the system would have far more potential to be catastrophic, not to mention without a solid design dependencies on energy and connectivity could easily be introduced.
‘On top of that, a vulnerability in the design of the system would put anyone from individuals to society as a whole at risk.
‘These dangers can be partly designed around, for example the European Central Bank’s proposal includes an offline component that retains the anonymity of cash along with many of its benefits – but does still require electricity and any such offline digital currency is at risk of theft along with the device carrying it.’
On Saturday, Sainsbury’s had said that it could not deliver most online grocery orders and was unable to contact customers directly.

But a Sainsbury’s spokesperson later said: ‘We can confirm that contactless payments are now back up and running in all stores, alongside all other forms of payment.

‘Our Groceries Online ordering system is working as normal and customers can place an order for delivery any time from tomorrow.
‘We apologise to customers for the inconvenience caused by technical issues today – thank you for bearing with us.’
One customer said she was meant to have a ‘very important’ order delivered between 8 to 9am, which did not happen.
Yvonne, 56, from the Reading area, said: ‘The main issue I have with this is the poor communication from Sainsbury’s to its customers.
‘It was obvious something was wrong at 7am as that’s when they send the receipts normally. Couldn’t get through to anyone about my 8 to 9 delivery.
‘No statement until about 8.30, only seemed to be on social media which not all customers will have.
‘Should have been an email or text to customers which would have helped those like myself expecting an early morning delivery. Much to improve on with their communications.’
Argos, which is owned by Sainsbury’s, was also affected by the software update, meaning some customers may have had issues ordering new items or collecting orders in-store.
It said there may have been delays in fulfilling orders placed.
Only a small proportion of Tesco orders due for delivery on Saturday were impacted, it is understood.
Tesco customers received an email if their order was disrupted, and if it was cancelled they were not charged.

Tesco said: ‘The vast majority of our online orders are being delivered as normal, but due to a technical issue earlier today we have had to cancel a small number of orders.
‘We are contacting affected customers directly, and we’re really sorry for the inconvenience.’
It comes after McDonald’s apologised to customers last Friday after they were unable to order food following an IT system outage in its restaurants.
The fast food operator later said the problem had been ‘resolved’ at its sites in the UK and Ireland.
On Friday morning, customers in the UK, , New Zealand and Japan complained about issues trying to buy from the fast food giant on social media.
In the UK, a number of customers said on social media that their local restaurants were closed although they were able to make orders through the company’s app.
Most stores across the UK opened as usual on Friday morning despite the problem.
The company blamed the issue on a ‘technology outage’ and stressed that it was not linked to any cybersecurity issues.
A McDonald’s spokeswoman said: ‘We are aware of a technology outage which impacted our restaurants.
‘The issue has now been resolved in the UK and Ireland. We thank customers for their patience and apologise for any inconvenience this may have caused. The issue is not related to a cybersecurity event.’
It is understood that, at this stage, none of the IT failures are being investigated as a potential cyber attack on any of the firms.
It comes a fortnight after Greggs said 25,000 of its workers will share £17.6million in bonuses this month after the chain notched up a 27 per cent hike in annual profits.
Greggs delivered a bumper pre-tax profit of £188.3million for 2023, up from £148.3million the previous year after like-for-like sales in company-managed shops jumped 13.7 per cent.
Hot chicken goujons, potato wedges and pizzas flew off the shelves along with its sausage rolls and steak bakes as it expanded its evening hours.
On an underlying basis, pre-tax profits lifted 13.1 per cent to £167.7 million.
The company – has also insisted it is on track with plans set in 2021 to double sales over five years, and does not plan to increase prices over 2024.
Shops are also set to open in locations where it does not have a strong presence, such as industrial areas, roadsides, supermarkets, travel hubs and retail parks.
It has ambitions to open between 140 and 160 stores in 2024 as it aims for ‘significantly more than 3,000 UK shops’ in total in the future.
The business now operates 2,473 shops after 145 net openings last year.
