Switching broadband and energy: what to check first

Last updated 16 October 2026 · All guides

Switching can save money, but the cheapest headline price is not always the best deal. Run through these checks first so there are no surprises.

Before you start

• Find your contract end date. Leaving early can mean exit fees, so check before you act. Your provider must tell you when your minimum term is about to end.
• Have your details to hand. For broadband, your postcode and current provider. For energy, your recent bill, meter readings and tariff name.
• Work out what you actually use. A yearly energy usage figure on your bill makes quotes more accurate.

Broadband: what to compare

• Speed you will really get at your address. Providers must give you an estimated speed before you sign up.
• Contract length and price rises during it. Check whether there are mid-contract increases and how they are described.
• Set-up and delivery costs, any router fee, and whether there is an engineer visit.
• Customer service and reliability. Ofcom publishes advice and complaints information.

Energy: what to compare

• Fixed or variable. Fixed deals protect you from price changes for a set time but may have exit fees. Variable tariffs follow the market.
• Unit rates and the standing charge, not just the monthly figure.
• Take a meter reading on the day you switch and keep a photo.
• Check customer service and payment terms. Ofgem, the energy regulator, has guidance.

Good habits

1. Put the end date of every contract in one place and set a reminder about a month before.
2. Compare at least a few options, using a comparison service you trust.
3. Read the key facts before agreeing, and keep a copy.
4. If you are struggling with bills, free help is available from MoneyHelper and Citizens Advice.
