The monthly price is the number providers compete on, so it is the number they optimise. Everything else gets moved out of it.
Most of those extras are legitimate. Some are avoidable. A few are worth walking away from. This is what to look for, roughly in the order you will meet them.
Before you sign
Activation or setup fee
Typically £0-£50 on residential broadband, and increasingly £0 because providers use “free setup” as a selling point.
Whether it matters depends entirely on contract length. Over 24 months, £30 is £1.25 a month and effectively noise. On a one-month rolling deal it can exceed the monthly rental — a £30 setup on a £19.95 tariff means your first month costs £49.95.
That inversion is why we include setup in every cost figure on this site, and why rolling deals show a one-month total: for the people most likely to take a short-term deal, the setup fee is not a footnote, it is the largest single charge they will pay.
Negotiable? Often, especially at the end of a month or quarter. Ask.
Router charges
Three models, and the difference is real money:
- Included free — the norm for most residential deals.
- Upfront purchase, £50-£150 for a better unit. Sometimes genuinely worth it.
- Delivery charge on an otherwise free router. Usually under £10 but frequently not shown until checkout.
Watch for routers that are “free” but must be returned at the end of the contract, with a non-return charge that can be £50-£100. Keep the box.
Engineer installation
Usually free where an engineer is needed at all. Charges appear when:
- there is no existing line and one must be installed
- you want the socket somewhere non-standard
- it is a new-build with no infrastructure
A full new fibre installation to a property that has never had one can be quoted at several hundred pounds by some providers and zero by others, because they treat it as a customer-acquisition cost. Worth getting two quotes if you are in this position.
Upfront payment
Some providers take the first month, the setup fee and the router charge together at order. If money is tight, ask what the day-one total is rather than the monthly price.
During the contract
The mid-contract rise
On new consumer contracts, providers must now state any in-contract increase in pounds and pence before you sign, rather than tying it to inflation. That is a real improvement, but the increase still exists.
One thing to note: a flat increase is regressive. £3 a month is 15% on a £20 package and 6% on a £50 one. If you are choosing between a cheap deal that rises and a slightly dearer one that is fixed, do the year-two arithmetic — the gap narrows more than you expect.
Our guide to mid-contract rises covers this properly.
Late payment and paper billing
Late payment fees are commonly £5-£15. Paper billing charges of £1-£2 a month still exist at some providers — around £24 a year for something you can get free.
Non-Direct-Debit surcharges
Some providers charge more if you do not pay by Direct Debit. This is legal and reasonably common. It is also a meaningful cost over two years, and it disproportionately affects people without a bank account they can safely direct-debit from.
Going out of contract
Not a fee, but the biggest number in this article.
When your minimum term ends, most providers move you to a standard price which is frequently much higher than the new-customer rate for the identical service. Nothing is charged and nothing changes on your bill line — the price simply rises and stays risen.
For most households this costs more than every other charge on this page combined. It is also the easiest to fix: you can leave whenever you like, with no penalty.
Leaving
Early termination charges
Leave before the minimum term ends and you normally owe the remaining months, sometimes discounted for costs the provider avoids.
This is the number that makes long contracts risky if there is any chance you will move. Eight months into an 18-month contract at £25, the exit charge is around £250 — considerably more than the flexibility premium on a rolling deal would have cost you.
Ask, before you sign: what happens if I move house? Some providers will transfer the service instead of charging you. That single answer can change which deal is right.
Contract buy-outs
The mirror image, and worth knowing about: some providers will pay your existing exit fee to win your business. YouFibre advertises up to £300 in cash. If an exit charge is the only thing keeping you where you are, it may not be a barrier at all.
Non-return fees
Covered above. Return the router, get proof of postage.
Reconnection charges
If you leave and come back, or if service is suspended for non-payment and then restored, expect a reconnection charge. Usually £20-£40.
What is worth walking away from
Most of the above is ordinary. Three things are not.
A setup fee that is not disclosed until checkout. If the price changed between the comparison table and the payment page, that is a signal about how the rest of the relationship will go.
A contract where nobody can tell you the month-13 price. Under the current rules a provider selling to consumers should be able to state it precisely. Inability to answer is either a compliance problem or a training problem, and neither is reassuring.
A “free” router with an undisclosed non-return charge. Free means free. If it must come back, that is a loan, and the terms should be visible before you agree.
The arithmetic that actually protects you
Before signing, work out one number:
> Setup + router + delivery + (monthly × 12)
That is your first-year cost, and it is the figure that makes two deals comparable regardless of how they are advertised. It is the default sort on this site for exactly that reason.
Then ask two questions the first-year figure cannot answer:
- What is the price in month 13, and is it written down?
- What does it cost to leave early, and will they move the service if I move house?
Three numbers and two questions. That is the whole of it.
