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.

Editor's note
Telecoms is a mid-sized vertical in the UK agency market, with 82 agencies in this index positioning here. The category splits into four working shapes: tier-one consumer agencies that hold the mobile and broadband incumbents (EE, Vodafone, O2, VMO2, BT, Sky, TalkTalk); altnet specialists running local-rollout and brand campaigns for CityFibre, Hyperoptic, Community Fibre, Netomnia, and the long tail of regional fibre builders; MVNO challenger shops working with Tesco Mobile, Sky Mobile, Lebara, Lyca Mobile, iD Mobile, Smarty, and Giffgaff; and B2B telecoms agencies focused on connectivity, hosted voice, UC, and channel-partner programmes for resellers and MSPs. What makes telecoms distinct is the regulatory load on the marketing itself. From 17 January 2025 Ofcom banned inflation-linked or percentage-based mid-contract price rises in new contracts, requiring any in-contract increase to be set out in pounds and pence at point of sale. From 12 September 2024 the One Touch Switch regime took effect for residential fixed-line broadband and voice, making the gaining provider responsible for the whole switch and resetting the entire acquisition journey. The ASA's CAP guidance on broadband speed claims requires the headline speed to be achievable for at least 50% of customers at peak time (8 to 10pm) and described as 'average', with the same logic applied to descriptive terms like 'superfast'. The shifts in 2025 and 2026 are structural. Altnet coverage now reaches over 40% of UK premises, CityFibre raised £2.3bn in July 2025 to fund roll-up acquisitions, and the sector is moving from build-out to take-up and consolidation. The Vodafone-Three merger completed in June 2025, creating a 27 million-customer operator and reshaping the host-network map underneath every MVNO. The Telecoms Consumer Charter signed in 2026 by BT, Virgin Media O2, VodafoneThree, Sky, and TalkTalk tightened the public commitments around price-change comms. And the PSTN switch-off on 31 January 2027 has pulled 500,000-plus business lines into a forced migration window that is reshaping B2B telecoms marketing.

Regulatory landscape
Ofcom · ASA · ICO
speed-claim and price-rise rules govern every campaign

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.

Specialist signals
5 signals
of real telecoms experience
  • · 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
Sector watch-outs
5 to watch
in any telecoms pitch
  • · 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

5 questions our editors get most often, answered honestly. No agency-marketing speak.

Curated by humans

UK retainers cluster in three bands. B2B telecoms boutiques and channel-marketing specialists run £3,000-8,000 per month for a focused brief such as MSP demand gen or hosted-voice content and paid. Mid-market consumer and altnet specialists sit at £8,000-30,000 a month for integrated paid, brand, and local activation across a Ready-For-Service postcode footprint. Tier-one consumer-telco programmes for the MNOs and incumbent broadband providers run into seven figures monthly across creative, brand, performance, and partnerships, with major brand campaigns often briefed at £1m-£10m per push. Sponsorship, retail, and field-marketing layers (altnet door-drop, sports rights, retail activation) sit on top. Compliance and ASA pre-clearance support is usually scoped inside the retainer for specialists.
