Spending audit playbookUpdated April 2026

The 30-minute switch that saves £180-£420 a year

Anyone on a default tariff, an out-of-contract broadband deal, or a mobile contract older than 18 months

The single highest hourly-rate task in personal finance is rebidding utilities. UK households on default energy tariffs pay £180-£420/year more than equivalent fixed deals; out-of-contract broadband customers pay £8-£15/month over the loyalty discount price. The whole exercise takes 30 minutes if you know what to compare and how to use the cancellation lever.

The 5-step playbook

Rebid your energy and broadband in 30 minutes

  1. 01

    Pull last 3 months of energy bills (or smart meter app)

    You need annual kWh usage for both gas and electricity. Most apps show this on the homepage; on PDF bills it's usually on page 2-3. Without this number, every comparison engine guesses (badly).

  2. 02

    Run a comparison on Uswitch or MoneySavingExpert Cheap Energy Club

    Both are independent. Both surface the same top 5-10 deals. Pick a fix length you can commit to (12 months is usually best in 2026 - shorter risks rolling onto a default tariff again).

  3. 03

    Call your current broadband provider and threaten to leave

    Don't switch; ring retentions. Ask for the new-customer price. The standard 2026 retention discount is £8-£12/month for 12-18 months. If they won't match, switch via Uswitch - you'll get an even better deal as a new customer elsewhere.

  4. 04

    Audit your mobile if you bought a phone with the contract

    If your phone is paid off and you're still on the original contract, you're paying £15-£25/month for nothing. Switch to a SIM-only deal at £8-£15/month. SMARTY, iD Mobile and Lebara give the best 2026 sub-£10 deals.

  5. 05

    Set a calendar reminder for the contract end-date

    Energy fixes are 12 or 24 months, broadband 18 or 24 months, mobile 12 or 24 months. Auto-renewal at the default rate is where the £200-£400/year leak returns. Reminder + repeat is the entire game.

FAQ

Honest answers

How much does the average switch save?

Member cohort median in 2026: £218/year on energy, £108/year on broadband, £96/year on mobile. Top quartile clears £600+ across all three.

Will switching disrupt service?

Energy switches are seamless - same wires, just a different supplier. Broadband switches over the same line are usually 1-2 hours of downtime; switching to a different network type (FTTP, Virgin) needs an engineer install. Mobile switches via PAC code are next-day.

Should I bother if I'm already on a fix?

Check your fix end date. If it's within 49 days, you can lock the next deal now without exit fees. If it's further out, set a reminder for 49 days before and skip until then.
