How to read a broadband advert

The large type is a mood. The small type is the product. Here is the order in which to read both.

A broadband advert is a haiku written by a lawyer. Eighteen months of a household’s money have to fit into a poster that can be read from a bus. What survives in 120-point type is the monthly teaser and a speed with an “up to” in front of it. What pays for the poster is everything underneath.

The order to read it

  1. Network and technology — full fibre, cable, or something older.
  2. Average speed, then the “up to” ceiling. The average is the adult in the room.
  3. Contract length and the promotional window. They are often not the same number of months.
  4. The pounds-and-pence mid-contract rise, with its date.
  5. Setup, delivery, installation, a “from” price that applies only with a paperless bill.
  6. Who the advert is actually for: new customers, existing, students, social-tariff eligible.

Advertising rules in the UK have already pushed retailers toward average-speed claims rather than a lonely maximum. They have not pushed retailers toward putting first-year cost in the hero number. That is still your job, or a comparison’s job.

If a deal only works when you ignore the footer, it does not work.

What we refuse to echo

We will not say “free” when a router deposit or delivery charge exists. We will not say “unlimited” as if it were a personality. We will not say “no downtime” because One Touch Switch exists. We will not say “Ofcom-approved deal”. Ofcom does not bless posters. We will put mock catalogue data in a labelled box rather than in a fake urgency clock.

Once you can read an advert, a comparison table becomes almost easy. It is the same small print, arranged so the year is visible. That is the whole craft.

From, fibre, unlimited

The three words that do the most work. From needs the extras added back. Fibre needs a technology name. Unlimited needs a paragraph on radio. Screenshot the artefact. The ASA piece in this issue is where that screenshot goes. Your contract is still the provider.

Questions

What does “up to 900 Mbps” mean?
It is a ceiling, not a typical evening speed. UK advertising should also give an average-speed figure for the package. Your address, wiring and Wi-Fi will still sit below a laboratory maximum.
Why is the big price only for 12 months?
Because it is a promotional rate. The in-contract or rolling price after that, plus any pounds-and-pence April step, is the rest of the product.
What does “from” mean?
Often the price with paperless billing, a longer contract, or without a landline. The price you will pay is the one that matches the options you actually tick.
Is “unlimited” actually unlimited?
It is not a personality. Fair-use and traffic management still exist on some products. Read the policy if you run a small office from a spare room.
Is a comparison table an advert?
When it promotes a deal, yes. Ours should still name the plant, include VAT, and never say Ofcom-approved. If we fail that, we have failed the piece.
