Telecoms advisers
Yes. Telecoms consultants sell advice that clients act on with real money: which supplier to buy from, which lines and contracts to end, how a phone system should be built and what to do before the copper network is switched off. When that advice is wrong, the client’s loss is financial and the claim is for negligence, which public liability does not cover. Professional indemnity insurance does, subject to the policy terms. If you also resell services or install equipment, tell your insurer, because those activities carry different risks.
Part of: Professional indemnity for IT professionals
In short
Telecoms consultants are judged on the accuracy of their audits, the soundness of procurement and design advice, and whether they found out what each line was really doing. GOV.UK says all users of the Openreach PSTN need to be migrated to new services by 31 January 2027, and lists alarms, telecare, door entry, payment terminals and lifts among the services that may need upgrading. Mobile networks will switch off 2G between 2029 and 2033. Ofcom expects providers to offer customers who depend on their landline a way to reach the emergency services for at least an hour in a power cut. PI covers negligent advice; it does not pay fee disputes or guaranteed savings.
Last reviewed 5 October 2026 by the Apex professional indemnity team.
A telecoms consultant’s product is a recommendation. Which carrier to choose, which contracts to exit, how a cloud voice platform should be built, how many mobile connections a business really needs, and what to do before analogue lines disappear. Clients act on it by signing multi-year contracts, ceasing lines and replacing equipment. If the recommendation is wrong, the cost lands on them first, and then on you.
Those losses are financial: higher charges than forecast, termination fees, a contact centre that turns callers away, an alarm that stops reporting. Public liability (PL) insurance is built for accidental injury and accidental damage to property, such as knocking a client’s comms cabinet during a site survey. It does not respond to a complaint that your audit, specification or design was negligent.
Professional indemnity (PI) insurance does. In the technology market it is usually written as technology errors and omissions cover, and it pays to defend the claim and any damages awarded, subject to the terms. Cyber insurance usually covers a different event: an attack on your own systems, which hold client invoices, network diagrams and logins for carrier portals. A breach there is a cyber claim first, and becomes a liability claim only if clients allege your security let them down.
The scenarios below are illustrative. They show the type of allegation telecoms consultants face, not real claims or outcomes.
Each is an allegation that you did not show the skill and care of a competent telecoms consultant. None involves the accidental injury or damage PL is designed for.
The switch-off is the biggest single piece of advice many telecoms consultants will give this decade, and the easiest to get wrong, because the lines that matter most are often the ones nobody uses for calls.
GOV.UK says the PSTN is being switched off by the telecoms industry by January 2027, and its connectivity timeline says all users of the Openreach PSTN will need to be migrated to new services by 31 January 2027. Its guidance lists alarm systems, telecare devices, door entry systems, fire and other alarms, payment terminals, lifts, intercoms and business broadband among the services that may need upgrading. It tells businesses to review whether any of their infrastructure relies on legacy networks such as the PSTN or ISDN, and to check with the provider of each piece of equipment that it works with digital lines.
| Source | What it says | Why it matters to your PI |
|---|---|---|
| GOV.UK: PSTN migration | All users of the Openreach PSTN need to be migrated to new services by 31 January 2027. | Switch-off advice given now is tested against a fixed date. |
| Fixed Telecoms Modernisation Charter (voluntary) | Signatories announce switch-off dates at least 12 months ahead and give direct customers at least 60 days’ notice; they will not migrate or cease services without exhaustive efforts to identify and engage customers, including vulnerable ones. | Sets the timetable your client’s providers have signed up to, and the checks they are expected to make. |
| Ofcom General Condition A3 and power-cut guidance (October 2018) | Providers must take all necessary measures to ensure uninterrupted access to emergency organisations. Ofcom expects at least one solution giving access for a minimum of one hour in a power outage, free to customers at risk because they depend on their landline. | Voice designs that ignore emergency access and power resilience will be compared with this. |
| GOV.UK: 2G switch-off | UK mobile networks will switch off 2G between 2029 and 2033; the first announced retirement starts in May 2029. | Fleet, IoT and alarm strategies that lean on 2G have a short life. |
| Ofcom General Conditions for business customers | All businesses must be billed accurately and given at least one month’s notice of a contract change that is not to their benefit, with the option to exit penalty-free. Providers must publish service levels and guarantees for standard SME contracts. Customers with ten or fewer employees must consent before a contract renews. | Billing recoveries and renegotiations rest on these rights. Missing one can cost the client money. |
None of these makes you a regulated adviser. They are the reference points a client, its new provider or an expert witness will use to judge whether your advice was sound.
Many telecoms audits are paid as a share of the savings or refunds found. That model is legitimate, but it shapes the claims you face and the cover you can buy.
| Usually covered by PI | Often excluded or limited | Needs a different policy |
|---|---|---|
| Negligent cost audits and bill analysis | Disputes over your own fees or share of savings | An attack on your systems or the client data you hold (cyber) |
| Procurement advice and tender evaluation errors | Savings or outcomes guaranteed in your contract | Injury or damage during a site survey (public liability) |
| Voice, unified communications and contact-centre design errors | Defects in equipment you supply or resell | Liability for hardware you sell (product liability) |
| Switch-off and migration advice, including line and device inventories | Injury claims linked to a failed alarm or emergency line, depending on the wording | Your laptop and test equipment (equipment cover) |
| Mobile fleet and network strategy advice | Fines and penalties, which PI wordings commonly exclude | Injury to your own staff (employers’ liability) |
| Defence costs, including telecoms expert witnesses | Problems you knew about when the policy started | Claims against your directors over how the firm is run (D&O) |
All of this depends on the policy wording. Make sure the business description names every service you offer, from audits to switch-off programme management.
Public sector bodies, housing providers and larger businesses usually set a PI limit in their consultancy terms or framework agreements. Size yours to the value of the contracts you influence, not your fee: a procurement for a multi-site estate can commit a client to years of spend.
A complete proposal gets better terms than a bare one, and a broker can only present what you tell us. Have these ready:
Speak to a broker
PI for telecoms consultants, placed by a named broker
Start the online proposal and save it as you go, or leave your number and a named broker will call you back, usually the same working day.
Apex Insurance Brokers is an independent insurance broker based in Bristol, established in 2009 and authorised and regulated by the Financial Conduct Authority. We are not tied to one insurer: we work with over 30 markets, including Lloyd’s syndicates through wholesale brokers, and every client has a named broker who handles the placement, mid-term changes, certificates for clients and the renewal.
Yes. Clients sign contracts, cease lines and redesign phone systems on your advice, so a mistake causes financial loss that public liability does not cover. PI pays defence costs and compensation when a client alleges your audit, procurement or design advice was negligent, subject to the policy terms.
No law requires telecoms consultants to hold PI, and Ofcom’s General Conditions apply to communications providers rather than independent advisers. In practice public sector buyers, housing providers and larger businesses usually make PI a condition of the appointment, often with a minimum limit and a requirement to keep cover for some years afterwards.
Usually, if switch-off planning falls within the professional business you have declared. Claims tend to involve lines ceased or migrated without checking what was connected, such as alarms, lifts or telecare. Record each device, who confirmed it works on a digital line, and any risk the client chose to accept.
Possibly, if your advice caused the failure, for example by recommending a cease without tracing the line. GOV.UK tells businesses to check with the equipment provider that devices work with digital lines, so agree in writing whether you or the equipment supplier confirms compatibility.
It can respond if the client alleges your analysis was negligent and it lost money as a result. It will not pay out on a guarantee of savings written into your contract, and disputes over your own fees or share of savings are usually excluded.
Usually. You hold invoices, diagrams and carrier portal logins for many clients, which makes you a useful target. Cyber insurance usually pays your own response costs after an attack. Claims from clients harmed by the breach may fall under the cyber policy’s liability section or under PI, depending on the wordings.
