Telecommunications agencies.
Telecoms marketing is the creative, performance, and brand work that grows demand for mobile networks, broadband, MVNOs, and business connectivity in a heavily regulated UK market. It is distinct because Ofcom governs switching and price-rise comms, the ASA enforces a 50%-at-peak-time speed-claim rule, and altnet rollout plus the January 2027 copper switch-off are reshaping the channel mix.

Three regulators set the rules. Ofcom enforces the mid-contract price-rise regime that took effect on 17 January 2025: any in-contract price increase written into a new contract must be expressed in pounds and pence prominently at point of sale, and inflation-linked or percentage-based escalators (CPI plus 3.9% and similar) are banned in new agreements. Ofcom also runs the One Touch Switch regime, live since 12 September 2024 for residential fixed-line broadband and voice, which makes the gaining provider responsible for the whole switching journey and requires the losing provider to respond electronically within 60 seconds. The ASA and CAP enforce the broadband speed-claim guidance: numerical speeds must be achievable for at least 50% of the relevant customer base at peak time (8 to 10pm), described as 'average', and substantiated by user data; descriptive terms such as 'superfast' are policed under the same logic. The ICO enforces UK GDPR and PECR across acquisition, retention, and switching comms, and the 2026 voluntary Telecoms Consumer Charter signed by BT, Virgin Media O2, VodafoneThree, Sky, and TalkTalk added public commitments on the clarity of price-change communication.
- · Fluency in the January 2025 Ofcom price-rise rules: knows the pounds-and-pence requirement, the new-versus-existing-contract distinction, and how to write switching and renewal comms that clear it
- · Speed-claim substantiation discipline: can build a paid and organic campaign against the ASA's 50%-at-peak-time rule with user-measured data and 'average' descriptors baked in
- · Named case studies with UK consumer telcos (EE, Vodafone, O2, VMO2, BT, Sky, TalkTalk), altnets (CityFibre, Hyperoptic, Community Fibre, Netomnia), or MVNOs (Tesco Mobile, Sky Mobile, Lebara, Lyca, iD, Smarty)
- · Altnet rollout literacy: understands door-drop, local press, sponsorship, and field-marketing mechanics around a Ready-For-Service postcode list, not just generic SaaS performance
- · B2B telecoms and channel-partner experience: can run an MSP or reseller demand-gen programme, has handled PSTN switch-off comms, and knows how hosted voice, SIP, and UC products sell into IT buyers
- · Speed claims in the work samples that lean on 'up to' framing or unverified marketing-team figures, with no view on the ASA's 50%-at-peak-time test or 'average' descriptor
- · Price-rise and renewal comms in case studies that still use CPI plus a percentage, with no awareness that any new-contract escalator from 17 January 2025 must be expressed in pounds and pence
- · Switching-journey work that treats acquisition as a lead-form fill, with no plan for the One Touch Switch flow, no integration with the gaining-provider switch journey, and no in-life churn signal
- · Altnet positioning that reads like generic SaaS or broadband-comparison copy, with no Ready-For-Service field-marketing layer, no local press or sponsorship, and no view on incumbent competitive response
- · B2B telecoms pitch with no PSTN switch-off communications plan, no view on the 31 January 2027 deadline, and no track record with hosted-voice, UC, or channel-partner programmes
