📋 Quick Summary

✅ Always compare full contract cost

✅ Price certainty can save £50–£150+ over 2 years

📈 Why do broadband prices rise mid-contract?

THE CLAUSE

CPI + 3.9%

Most large providers include clauses allowing annual increases.

Typical wording: "Your monthly price will increase each April by CPI + 3.9%."

EXAMPLE

If inflation is 5%:

5% + 3.9% = 8.9%

On a £35 plan: £3.11 increase per month

Over 24 months, that adds up significantly.

EXAMPLE: HOW MUCH DO PRICE RISES ADD?

£32/month broadband with 8% annual increase

Year 1: £32

Year 2: £34.56

Extra cost in year two:

£2.56 × 12 = £30.72

Multiply that over multiple years and it becomes meaningful.

🔒 Providers that may offer fixed-price deals

✅ FIXED PRICE

Alt-Nets often offer:

✓ Fixed monthly pricing for contract duration

✓ No CPI-linked increases

✓ Clear upfront pricing

📡 ALT-NETS

Hyperoptic

Community Fibre

Regional fibre ISPs

Availability depends on postcode.

📅 12 vs 24-month contracts & price rises

12-MONTH CONTRACT

Pros: Shorter exposure to price increases, more flexibility

Cons: Higher monthly rate

24-MONTH CONTRACT

Pros: Lower starting monthly price

Cons: Greater exposure to annual increases

Sometimes a fixed 24-month deal can outperform a cheaper CPI-linked plan long-term.

⚠️ Fixed-price vs promotional pricing

✅ FIXED PRICE

Same price for full contract

No surprises

❌ PROMOTIONAL

Discounted first 12 months

Then higher standard rate

Always check: What happens after month 12? Whether CPI applies? Whether increase is guaranteed?

🔍 How to compare broadband without price rises

Check "Price Increase" section in terms

2️⃣

3️⃣

4️⃣

5️⃣

Check exit clauses

⚖️ Example comparison

DEAL A (CPI + 3.9%)

£30/month

Price rise in year two

Estimated 24-month total: ~£750

DEAL B (FIXED PRICE)

£32/month

No increase

24-month total: £768

Difference: £18 — but if inflation rises, Deal A could exceed Deal B.

Predictability often provides peace of mind.

🤔 Is avoiding price rises worth it?

DEPENDS ON:

✓ Your tolerance for uncertainty

✓ Inflation trends

✓ Contract length

✓ Budget stability

CONSIDER FIXED PRICE IF YOU:

✓ Want predictable monthly expenses

✓ Are budgeting tightly

✓ Are on a fixed income

✓ Dislike mid-contract surprises

✓ Plan to stay full contract term
