Post Office Broadband was a fourteen-year-old home internet service that ended not through failure but through a deliberate corporate decision to exit a market that had little to do with the institution's core purpose. The Post Office launched a broadband and home phone service in 2007 and ran it until February 2021, when it agreed to sell the entire customer base of approximately 465,000 to Shell Energy. The service was always simple, always Openreach-based and always aimed at customers who valued a trusted name over technical sophistication. For most of its existence it performed adequately on customer service measures. The Post Office's departure from broadband was a straightforward business retreat: the organisation said it wanted to concentrate on mail, banking and bill payments.
Why the Post Office offered broadband
By 2007, broadband was a mass-market product and many companies outside the traditional telecoms sector were entering the market. Energy suppliers, supermarkets and retailers had all concluded that broadband was a service their customers would take if offered alongside their existing relationship. The Post Office had a national retail presence, a well-established name and a customer base that skewed older and more cautious in its purchasing decisions. Broadband was a natural addition to the range of financial and utility services it was already selling through its branches and by post.
The service ran over the Openreach network (BT's infrastructure division, which owns the physical telephone line connections to most UK homes and the exchanges that route broadband signals). The Post Office did not own any of its own telecoms infrastructure. It operated as a reseller, initially under a managed wholesale service arrangement with TalkTalk's wholesale arm. This meant the underlying quality and reliability of the connection was similar to what a customer would receive from any other Openreach-based provider. The Post Office's contribution was the brand, the customer relationships and the customer-facing service.
Post Office Broadband packages and pricing
Post Office Broadband kept its range simple throughout its life. The offer typically comprised ADSL (the older standard telephone line broadband technology, delivering speeds generally between 3Mbps and 17Mbps depending on the distance from the telephone exchange) and FTTC fibre (Fibre to the Cabinet, where fibre runs to a street cabinet with the remaining copper section to the home delivering speeds up to 76Mbps). Both were sold as unlimited packages, which by the mid-2010s had become the market standard.
Pricing was competitive within the market. The Post Office did not attempt to be the cheapest broadband provider, but its packages were broadly in line with mid-market offers from comparable providers such as SSE and John Lewis. Customers could pay their broadband bills in a Post Office branch, an option that was retained even after the sale to Shell Energy; Shell confirmed during the transition that customers could continue to use Post Office branches for payments.
Customer service performance was above average for much of the service's life. Ofcom (the communications regulator) quarterly complaints data, which covers the UK's larger ISPs, consistently showed the Post Office below the industry average for broadband complaints in the periods when it was large enough to feature in the data. This was one of the factors that made the customer base attractive to Shell when it sought a broadband acquisition in 2020 and 2021.
The sale to Shell Energy
In February 2021, Post Office Limited agreed to sell its broadband and home phone business to Shell Energy Retail for an undisclosed sum estimated at between £80 million and £100 million. Shell had been seeking to grow its broadband business after entering the market through the acquisition of First Utility in 2018. At the time of the deal, Shell had around 130,000 broadband customers. Adding the Post Office's 465,000 customers in a single transaction took it to nearly 600,000 and gave it the scale to appear in Ofcom's individual ISP complaints data for the first time.
The Post Office said its motivation was to focus on its core services: mail and parcel handling, cash and banking, bill payments and travel products. Nick Read, chief executive at the time, described it as a good deal for the organisation, its postmasters and its customers. Postmasters who had previously earned income from signing up broadband customers received a one-off payment as part of the arrangement.
The transfer of customers to Shell Energy took place in March 2021 and was described as seamless. Shell and the Post Office both operated on Openreach infrastructure, which meant no technical migration of physical equipment was required. Customers were sent letters from both companies explaining the change. Their service, pricing and contracts were maintained.
What happened to Post Office Broadband customers after 2021
The Post Office's former broadband customers passed through two further changes of ownership after the Shell acquisition. When Shell decided to exit the UK retail energy and broadband market in 2023, Octopus Energy acquired the whole Shell Energy Retail business in December 2023. Octopus had no interest in running a broadband operation; it was focused on the energy customers. The broadband base was sold to TalkTalk, which had already been providing the wholesale network infrastructure underpinning Shell's service. TalkTalk confirmed the acquisition in early 2024 and began migrating the customers onto its own systems through 2024.
Customers who had originally joined the Post Office for broadband in 2007 and had remained throughout therefore passed through four different companies between 2021 and 2024: from the Post Office to Shell Energy to Octopus Energy and finally to TalkTalk. Most will have noticed the company name changing on their bill and little else.
In summary
Post Office Broadband served its customers without distinction for fourteen years. It was not a technically noteworthy service; it did not build its own network, did not lead on speed, and did not attract technically demanding users. What it did was provide a reliable, uncomplicated connection under a name that a particular segment of the market trusted. Its complaint record was better than most. The decision to sell was a logical business choice from an organisation whose primary competences lay elsewhere, and the transition to Shell Energy was handled with a minimum of disruption. The customers it passed on were generally well-looked-after, which made them a valuable acquisition for Shell and, in time, for TalkTalk.
Key dates in Post Office Broadband’s history
Post Office Broadband launches
The Post Office launches a home broadband and telephone service, running over the Openreach network under a wholesale arrangement. The service is aimed at customers who value a recognisable, trusted brand over the cheapest available price. Packages include ADSL and, later, FTTC fibre options. The Post Office's extensive branch network provides a sales and support channel unavailable to most competitors.
Fourteen years of operation; complaints consistently below industry average
Post Office Broadband operates for fourteen years, offering simple, unlimited ADSL and fibre packages. Customer service performance is consistently better than the industry average in Ofcom complaints data during periods when the customer base is large enough to be measured individually. The service does not offer ultrafast packages or LLU-based speeds, remaining a straightforward Openreach reseller throughout.
Post Office agrees to sell its telecoms business to Shell Energy
Post Office Limited agrees to sell its entire home phone and broadband operation to Shell Energy Retail for an undisclosed sum estimated at between £80 million and £100 million. The business has been operated since 2007 and supplies approximately 465,000 customers. The Post Office says the sale allows it to focus on mail, banking, bill payments and travel. Postmasters receive a one-off payment in compensation for lost sign-up revenue.
465,000 customers transferred to Shell Energy Broadband
The transfer of Post Office broadband and phone customers to Shell Energy completes. Both providers operate on Openreach infrastructure, so no physical migration is required. Customers continue on their existing contracts and pricing. They can still pay their broadband bills in a Post Office branch. Shell's total broadband customer base rises from around 130,000 to nearly 600,000 as a result of the transaction.
Octopus Energy acquires Shell Energy Retail; broadband base sold on to TalkTalk
Octopus Energy completes its acquisition of Shell Energy Retail, taking the energy customers. The broadband base of approximately 480,000 to 500,000 customers (including those originally from the Post Office) is sold to TalkTalk, which was already running the wholesale network behind the service. TalkTalk confirms the acquisition in early 2024 and begins migrating customers. Former Post Office broadband customers have now changed company names three times since 2021.
