Why broadband prices increase
"Your price will increase each April by CPI + 3.9%"
If CPI is 5%, your total increase becomes:
8.9%
On a £35 plan, that's an extra £3+ per month.
- Automatic increases
- Pre-agreed in your contract
- Applied even during minimum term
- Usually every April
7 proven ways to avoid price increases
-
Choose a fixed-price contract
Some providers offer fixed monthly pricing with no inflation-linked rises. These are often alternative fibre networks (Alt-Nets) and regional full fibre providers. Always check the "Price Changes" section before signing.
-
Consider 12-month contracts
Shorter contracts mean less exposure to annual increases and more flexibility. The monthly price may be slightly higher, but overall cost may be more predictable.
-
Switch when your contract ends
The biggest price jump often happens when promotional pricing expires. Set a reminder 30–60 days before your contract ends to avoid "loyalty penalties" that can be £10–£20 more per month.
-
Avoid auto-renewal
Standard out-of-contract rates are often significantly higher than new customer deals. Always review your deal before renewal.
-
Compare total 24-month cost — not monthly price
A deal with a slightly higher monthly price but fixed term may be cheaper than a lower headline rate with CPI increases.
-
Check for Alt-Net providers in your area
Alternative fibre networks often compete aggressively on price, offer symmetrical speeds, and avoid CPI-linked increases. Availability depends on postcode.
-
Don't overpay for unnecessary speed
Most homes only need 150–300 Mbps. Paying an extra £8/month for 1Gbps adds £192 over 2 years.

Add end-of-contract increases, and savings can exceed £100+ per cycle.
Fixed-price deal is only £16 more — but offers complete predictability.
What you can't usually do
If the increase was clearly written in your contract (e.g., CPI + 3.9%), you usually cannot cancel without early termination fees.
Checking terms before signing matters more than ever.
Red flags to watch before signing
"Price may increase annually"
CPI-linked clauses
Promotional pricing expires after 12 months
No clarity on second-year pricing
