Telecoms provider insurance: cover for UK connectivity, ISP and unified comms businesses

Reviewed by Matthew Bartlett, Director, Apex Insurance Brokers Limited · Last reviewed 2026-08-06

Telecoms companies sit in an unusual position among technology businesses. You are not just writing software or managing someone’s IT estate — you are running the connectivity that other businesses depend on minute by minute. When a leased line drops, a hosted phone system goes quiet or a broadband circuit fails, your customer’s losses start accumulating immediately, and their first call after the fault ticket is often to their solicitor or their own insurer. That makes your insurance programme less of a formality and more of a load-bearing part of the business.

This guide walks through the covers that matter for connectivity providers, ISPs, unified comms and VoIP businesses, wireless and fibre operators, and the managed service providers who resell or wrap telecoms services. It is written for the owner or director who wants to understand what each policy actually does before talking to a broker — not a list of products, but the reasoning behind them.

Why is telecoms different from ordinary IT business insurance?

Three things set communications providers apart from the average technology firm. First, the harm profile: when a software consultancy makes a mistake, the client usually discovers it over days or weeks. When a telecoms service fails, the client feels it in seconds, and the damage — missed orders, dead call centres, offline card terminals — is easy for them to quantify and claim for. Second, the physical footprint: most telecoms businesses put engineers into customer premises, comms rooms, risers and street cabinets, and many own or lease equipment distributed across dozens of sites. Third, the regulatory backdrop: UK communications providers operate within Ofcom’s framework, which brings obligations that a generic IT firm never encounters.

A standard off-the-shelf “IT company” policy can miss all three. Policy wordings vary in how they treat failure of a service (as opposed to negligent advice), whether business interruption losses suffered by your customers are picked up, and how equipment away from your own premises is covered. This is exactly the sort of business where the detail of the wording matters more than the headline product names — and where a broker who understands telecoms contracts earns their keep.

What happens if a network outage costs our clients money?

This is the claim scenario that keeps telecoms directors up at night, and it is the core job of technology professional indemnity insurance. Tech PI — which you will also see called technology errors & omissions or tech E&O, the American name for broadly the same cover — responds when a client alleges that a failure in your professional service caused them financial loss. For a communications provider that might be a misconfigured router that took a client’s site offline during their busiest trading day, a botched number port that left a sales team unreachable for a week, a provisioning error on a leased line migration, or an SLA breach where the client claims consequential losses well beyond any service credits.

Two points deserve emphasis. The first is that tech PI is not a legal requirement — no statute compels an ISP or comms provider to hold it. In practice, though, it is almost always a contractual requirement: enterprise customers, public-sector frameworks, channel partners and carriers you resell for will typically insist on a stated PI limit (£1m, £2m and £5m are common contractual asks) before they will sign. Treat the limit in your contracts as a floor, not a target — the right limit reflects the losses a customer could actually suffer if your service failed, which for a client running a contact centre or e-commerce operation can be substantial.

The second point is about wording. Some professional indemnity policies were drafted with advisers in mind — accountants, consultants — and respond to negligent advice more comfortably than to the failure of a technology service. A good technology wording covers both, and should also address contractual liability (claims arising from breach of your service agreement, not just negligence), which matters enormously when your customer relationships are built on SLAs. This is one of the areas we scrutinise line by line when placing cover for comms providers.

We hold subscriber data — what does cyber insurance actually do for us?

Telecoms providers are data-heavy businesses whether they think of themselves that way or not. Subscriber records, call detail records, billing and payment information, network traffic metadata — all of it is personal data under UK GDPR and the Data Protection Act 2018, overseen by the Information Commissioner’s Office (ICO). Comms providers are also attractive targets: compromise a provider and an attacker potentially reaches every downstream customer, which is why supply-chain attacks so often route through connectivity and managed service businesses.

Cyber insurance earns its place in three ways. First, breach response: immediate access to incident response specialists, forensics, legal advice on notification obligations, and customer communications support — the expensive first seventy-two hours handled by people who do it constantly. Second, your own business interruption: if ransomware takes down your provisioning, billing or network management systems, the policy can cover your lost income and the extra cost of keeping services running. Third, third-party liability: claims from subscribers or business customers whose data was exposed or whose services were disrupted by an incident on your network.

One honest caveat, because it is often glossed over: regulatory fines are a different matter. Whether fines under UK GDPR can be insured at all is legally uncertain, and policies frequently exclude or restrict them. Do not buy cyber cover on the assumption it will pay an ICO penalty; buy it for the response costs, the interruption losses and the liability claims, which are the larger and more certain exposures for most providers anyway. Our guide to how cyber insurance works goes deeper on what these policies do and don’t cover.

Note also the overlap question: a client whose business was interrupted might frame their claim as your professional failure (a PI matter) or as the consequence of a security incident (a cyber matter). If your PI and cyber policies sit with different insurers on different wordings, you can end up with each pointing at the other. Buying the two covers in a coordinated way — ideally designed together — closes that gap.

Our engineers install and maintain kit on site — do we need public liability?

Yes, in practice. Public liability insurance covers injury to third parties and damage to third-party property arising from your business activities, and telecoms is one of the most physically active corners of the technology sector. Engineers pulling cable through ceiling voids and risers, drilling through walls for entry points, working in customer comms rooms alongside live equipment, lifting floor tiles, installing antennas and dishes at height — every one of those activities can damage property or injure someone who isn’t your employee.

The claims are rarely exotic: a drill through an unseen water pipe, a dropped tool damaging a client’s server, a trailing cable that trips a visitor, accidental damage to another tenant’s fit-out in a multi-occupancy building. What makes PL essential for comms providers is that customers and site owners will demand it — landlords, data centres and enterprise clients routinely require evidence of public liability at £5m or £10m before your engineers are allowed on site. If you use subcontract engineers, check how your policy treats them and insist on seeing their own cover; if you work at height or in more hazardous environments, disclose it, because undisclosed activities are a classic cause of declined claims.

Is employers’ liability insurance a legal requirement for our team?

Once you employ staff, almost certainly yes. Under the Employers’ Liability (Compulsory Insurance) Act 1969, UK employers are legally required to hold employers’ liability insurance, with only narrow exceptions (certain family-only businesses, for example). EL covers your legal liability if an employee is injured or made ill through their work — and for a telecoms business with field engineers, the exposure is real: manual handling, ladder work, working in ducts and lofts, driving between sites.

Two practical notes. First, “employee” is interpreted broadly for EL purposes — labour-only subcontractors and temporary workers you direct and control may count, so describe your workforce accurately to your broker. Second, if you engage contractors through personal service companies, remember that their tax status under the off-payroll working rules (IR35) is a separate matter entirely: it is a question of tax law, insurance neither changes nor determines it, and status questions belong with a qualified accountant or tax adviser, not an insurance policy.

How do we insure the network itself — equipment, PoPs and kit on customer sites?

Physical infrastructure is where telecoms diverges furthest from a desk-based IT firm, and where standard business property cover most often falls short. Think through where your equipment actually lives: routers, switches and servers in your own offices; kit racked in third-party data centres and points of presence; CPE — routers, handsets, access points — installed at hundreds of customer sites; stock in vans; test equipment travelling with engineers. Each location raises a question a generic policy may not answer: is property away from your premises covered, at what limit per site, and on what basis?

Points worth working through with your broker include:

• Equipment at unspecified locations — cover that follows CPE onto customer sites without you having to list every address.
• Kit in data centres and PoPs — confirming your policy responds there, and understanding what the facility’s own terms make you responsible for.
• Reinstatement realities — lead times on network hardware can be long; consider increased cost of working cover to fund workarounds while replacements ship.
• Vans, tools and stock — theft from vehicles is a persistent claims area for field-engineering businesses, and policies often carry specific conditions about overnight storage.

If you own fibre, masts or street furniture, the conversation gets more specialised still — that infrastructure needs to be valued and insured deliberately, not swept into a general contents sum insured.

How does Ofcom’s regulatory framework affect our insurance thinking?

Ofcom is the UK’s communications regulator, and providers of communications networks and services operate within its regulatory framework — general conditions and obligations touching areas such as consumer protection, complaints handling, and the security and resilience of networks. We won’t rehearse the rules here (they evolve, and your compliance obligations are a matter for your own regulatory advice), but the backdrop matters for insurance in two ways.

First, it raises the stakes of any incident. An outage or security event at a regulated provider isn’t only a customer-relations problem; it can trigger reporting obligations and regulatory scrutiny, which means legal costs and management time on top of the operational damage. Well-constructed cyber and management liability policies can help fund legal representation and response costs when regulators come asking questions — though, as with the ICO, do not assume any regulatory penalty itself would be insurable; that is often excluded or legally uncertain. Second, the framework’s emphasis on resilience is increasingly mirrored by insurers: underwriters looking at telecoms risks want to see redundancy, incident response planning and security controls, and providers who can evidence them are simply easier to insure well. Good compliance and good insurability tend to travel together.

How should a telecoms provider actually buy this cover?

Buy it as a programme, not a shopping list. The exposures above interlock — an outage can be a PI claim, a cyber event and a business interruption loss simultaneously — so the policies need to be chosen to fit together, with limits that reflect your contracts and no gaps or double-counting at the seams. A sensible process looks like this: map your services (connectivity, voice, hosting, managed services each carry different weight); pull the insurance clauses from your top customer and supplier contracts and note every required limit; inventory where your equipment physically sits; and then structure PI, cyber, PL, EL and property around that picture. Many providers end up with a combined technology policy wrapping PI and cyber together with the liability covers — our page on combined tech PI and cyber insurance explains when that structure works well.

The disclosure conversation matters more in telecoms than almost anywhere else in tech. An insurer quoting for “an IT company” that turns out to run an ISP with field engineers and owned infrastructure has been quoting for the wrong risk — and that mismatch surfaces at claim time, which is the worst possible moment. If you would rather talk it through than fill in forms, you can speak to an Apex technology specialist and we’ll ask the right questions the first time.
