How to compare UK tariffs
Unit rate (p/kWh) — the cost of the energy you actually use. The Energy Price Cap caps the unit rate on the default (Standard Variable) tariff. Fixed tariffs are usually slightly above or below the cap.
Standing charge (p/day) — what you pay per day even if you use zero energy. Covers network costs, smart-meter rollout and policy levies. About 53p/day for electricity and 32p/day for gas on a typical 2026 tariff.
Exit fee — what you pay to leave early on a fixed tariff. Typically £25-£75 per fuel. None on Standard Variable. None in the final 49 days of any fixed contract.
Headline rates lie. The only way to know is to compare against your real annual kWh. Selectra's comparison uses your postcode + 12-month usage to find the cheapest current deal.
Common questions
Every UK domestic energy tariff has two components: a standing charge (a flat fee in pence per day, even if you use zero energy), and a unit rate (in pence per kWh you actually consume). Your bill = (standing charge × days) + (unit rate × kWh used) + VAT (5%). Compare both numbers — a tariff with a low unit rate but a high standing charge can cost more than the reverse if you use little energy.
The Energy Price Cap set by Ofgem limits how much suppliers can charge for the default (Standard Variable) tariff. It is reviewed every three months. It does not cap fixed-term tariffs — those can be cheaper or more expensive than the cap depending on wholesale prices.
Most UK fixed-term tariffs include an exit fee (typical range: £25-£75 per fuel) if you switch before the contract ends. You can switch without an exit fee in the last 49 days of your contract. The default Standard Variable tariff has no exit fee.
Many UK suppliers offer 'green' or '100% renewable' tariffs which match your annual consumption with REGO certificates. This is a paper-trail match, not a guarantee that the electrons reaching your home are renewable — but it does fund continued renewable generation. Tariffs marked '100% renewable' below carry REGO backing.
If wholesale prices are forecast to rise, fixing locks in today's price for the contract length. If they are forecast to fall, the Standard Variable tariff (capped by Ofgem) tracks the wholesale market down. The right choice depends on your appetite for stability vs. potential savings — Selectra's comparison tool factors in both.
