Your connectivity supplier and your IT supplier are becoming the same company

On 14 August, TalkTalk Business and technology services provider ARO announced they are merging to create one of the UK's larger independent connectivity and managed service providers. The combined group brings together around 650 employees, annual revenues of roughly £200 million and a customer base of more than 70,000 organisations across connectivity, cloud, cyber security and managed IT. If you buy business broadband, phone lines or IT support from anyone, this is the shape of the market you are buying in.

What the deal actually is

TalkTalk Business was demerged from TalkTalk Group in 2023 and sold to the same group's own shareholders for £95m, completing its separation in February 2026. ARO, formerly Arrow, brings cloud, cyber security and datacentre services along with Microsoft Solutions Partner status, and is the larger of the two by earnings. The Register put the split of the combined revenue at roughly £130 million from fixed line, mobile and connectivity, with the remainder from IT and cyber security services. TalkTalk Business chief executive Ruth Kennedy described it as another step in the company's transformation into a managed services provider, following its earlier acquisition of Planet IT.

Nothing changes on Monday, and that is the point

Both businesses will initially keep their existing brands and offices, and the deal is still subject to clearance under the National Security and Investment Act because of ARO's government customers, which is expected to conclude by the end of the summer. Mergers of this kind rarely announce themselves to the customer. The changes arrive over the following year or two: account managers move on, overlapping product lines get rationalised onto whichever platform the new group standardises on, support desks combine, and renewal quotes start reflecting the new group's priorities rather than the old one's. None of that is automatically worse. It does mean the person who knew how your sites were wired may not be there when you next need them to.

This is the direction of travel, not a one-off

The same week, ISPreview reported that TalkTalk had moved a further 13,500 residential broadband customers to Fleur Telecom, part of the Horsham-based Telecom Acquisitions Group, in the latest of a run of piecemeal disposals from its consumer base. Kearney's annual telecom health index, published on 11 August, argued that some markets would benefit from more concentration, on the basis that larger operators can invest more effectively in a single network infrastructure. Whether or not that is right for the country, the practical effect for a smaller customer is that the supplier you signed with is less likely to be the supplier you renew with.

The questions worth asking now

Who is my named contact, and what is the escalation path when they are unavailable. Is the product I am on staying on the roadmap, or is there a migration coming. Does my contract contain a change of control clause, and what does it allow either side to do. When does it renew, when does the notice period start, and is it set to roll over automatically. Where does my data sit, and does anything about this move it. None of those are confrontational questions. A supplier worth staying with will answer all five without a fuss.

Why smaller firms feel it more

A 500-seat customer gets a transition plan and a named programme manager. A 12-seat customer gets an email. The practical defence is knowing your own setup well enough that you are not relying on a supplier to remember it for you: the line type and speed at each site, the numbers you own and who currently ports them, the contract end dates, the admin logins for your own domain and your own tenant. That information is yours. It is a great deal easier to collect while everything is working than during a migration you did not choose.
