Comparing energy tariffs is one of the more reliable ways to reduce household gas and electricity costs. The comparison tool above searches across multiple suppliers to find the current best available tariff for a given postcode and usage level. The latest deals are displayed above.
How energy comparison works
An energy comparison tool takes details including the current supplier, estimated annual usage and postcode, then searches available tariffs from multiple energy suppliers simultaneously. Results are ranked by estimated annual cost, allowing a direct comparison between available deals. Switching can typically be completed directly through the comparison platform without needing to contact the new supplier separately.
Fixed tariffs and the energy price cap
Energy pricing in the UK operates under an Ofgem price cap that sets the maximum standing charges and unit rates a supplier can charge customers on a default tariff. Fixed-rate tariffs, which lock in a price per unit for a set period, became available again from 2023 after a period during the energy crisis when most fixed deals were withdrawn. Whether a fixed tariff represents a saving over the standard variable rate depends on the price cap level at the time and market conditions. Comparing fixed and variable options before switching is the most straightforward way to identify whether a fixed deal is currently beneficial.
What to check before switching energy supplier
Before switching, checking whether the current tariff has an exit fee is worthwhile, as these apply on some fixed-rate contracts. The new tariff start date, payment method requirements and direct debit amount should also be confirmed before completing a switch. Switching between suppliers on standard variable rate tariffs carries no exit fee. The comparison tool above handles the comparison process and links through to the relevant supplier or switching service.
Energy comparison and NHS staff
There are no NHS-specific energy tariffs or discounts from energy suppliers in the UK. NHS staff access the same tariffs as all other domestic customers. The most effective way to reduce energy costs is through comparison and switching to the lowest available tariff for a given address. For other household cost comparisons, the Energy Help Line page covers additional options for reducing gas and electricity bills.
