1) Region matters

There are separate regional records because energy pricing differs across PES areas. Do not assume a headline price applies nationally.

2) Payment method affects price

Direct Debit, bill payment and prepayment variants can differ materially. Compare like-for-like only.

3) Economy 7 is usage-sensitive

Economy 7 can help if enough usage is overnight, but can cost more overall if most use is daytime.

4) Fuel bundle changes the comparison

Dual fuel should not be compared directly with electricity-only rows unless you normalise the usage assumptions.

5) Exit fees reduce flexibility

Records shown for this tariff include exit fees of up to £75.00 per fuel. Check the exact regional row before switching.

6) Postcode still beats region-only estimates

Region is useful for guidance, but a postcode-based quote is more precise because it reflects the actual tariff availability and pricing for your home.

Why are there so many records for the same tariff name?

Because the tariff can vary by service type, payment method, Economy 7 status and region. This page groups them together so you can compare them in one place.

Are prices for The Longer Fix v18 the same in every region?

No. This page includes region-level records because unit rates and standing charges differ across PES regions. Your postcode is still the best way to confirm what you would actually pay.

Does The Longer Fix v18 come with Economy 7?

Yes. At least one Economy 7 option group is currently listed on this page, with separate day and off-peak unit rates shown per region.

Can I get The Longer Fix v18 as electricity-only, gas-only or dual fuel?

Current records show these service types: Dual Fuel, Electricity, Gas. Availability still depends on your home and supplier rules.

How do I switch to the exact regional option I want?

Use the grouped comparison table to find the right option type, then choose the regional row below it that matches your area and click the switch link.

Can I compare this with other tariffs from the same supplier?

Yes. Visit the British Gas tariffs page to compare other current products from the same supplier.

Will switching affect my supply?

In normal circumstances, no. The switch is administrative and your supply continues while the new tariff is set up.
