The fastest way to lower costs: compare what’s actually available
Because supplier support and tariff availability change, a postcode-based comparison is often the quickest way to see whether a cheaper option exists for your home, meter type, and payment method. If you’re eligible for extra support, you can still compare — and then decide whether switching is the right move for you.
Before you compare (30-second check)
- Meter type: credit or prepayment; smart meter yes/no
- Payment method: direct debit, on receipt of bill, pay as you go
- Any debt on the meter/account: may affect switching options
- Economy 7 or multi-rate: matters if you use off-peak electricity
Good to know: If you’re on a fixed deal, check whether early exit fees apply before switching. Your supplier can confirm this on your account or bill.

Two realistic scenarios (illustrative examples)
Scenario A: low-income household eligible for WHD
Assumptions: household meets the scheme’s eligibility checks for the current year; electricity account is active; discount is applied once in the scheme year.
- Potential support type
- One-off bill discount (amount set by scheme year)
- What it changes
- Your bill total, not your unit rate
- What to do next
- Confirm WHD rules on GOV.UK, then compare tariffs to reduce ongoing costs
Why no exact £ figure here: the WHD amount and rules can change by year. Use official guidance for the current scheme details.
Scenario B: prepayment customer with arrears
Assumptions: customer has a prepayment meter with debt collection set as a weekly amount; household can afford only a small repayment while keeping the lights and heating on.
- Example affordability
- Agree a lower weekly debt recovery so more of each top-up goes to energy
- Practical steps
- Ask about emergency credit, friendly-hours, and PSR registration if vulnerable
- Switching impact
- Switching may be limited with certain prepay debts — compare options but check restrictions first
