Latest UK Domestic Energy Tariffs 2025 | Compare Gas & Electricity

Understanding UK Domestic Energy Tariffs

In the UK, your home energy bill is determined by your tariff, which sets how much you pay to your supplier for each kilowatt hour (kWh) of electricity or gas you use, plus a daily standing charge. The right tariff for you depends on your usage, meter type, location, and whether you prefer price certainty or flexibility.

Two main costs

Unit rate (p/kWh) — what you pay for each unit of energy used.
Standing charge (p/day) — a daily cost to maintain your connection.

Other things to check

Contract length and exit fees
Payment method (Direct Debit often lower)
Online billing discounts or perks

Smart meters

Smart meters support accurate billing and unlock time-of-use tariffs that reward off-peak usage.

Note: Actual rates vary by region, usage, meter type, and supplier. Always check the full tariff information label (TIL) before switching.

Latest UK Tariff Types Explained

Suppliers offer a range of tariffs designed for different homes and habits. Here’s how the most common options compare.

Tariff type	What it is	Best for	Things to watch
Standard Variable (SVT)	Rates can move up or down and are limited by the Ofgem price cap for typical usage.	Flexibility, no/low exit fees.	Bills can rise when market prices rise.
Fixed-rate	Unit rates and standing charge fixed for 12–24 months.	Budget certainty and price protection.	Early exit fees may apply; could pay more if prices fall.
Tracker/Indexed	Rates track wholesale or market indicators within set limits.	Those comfortable with some fluctuation for potential savings.	Rates can change frequently; read limits and rules.
Time-of-Use (Smart)	Cheaper off-peak rates, higher peak rates; requires smart meter.	EV charging, heat pumps, shifting usage to nights/weekends.	Peak prices can be high; shift habits to benefit.
Economy 7/10	Two-rate tariffs with 7–10 off-peak hours for electricity.	Homes with storage heaters or heavy night usage.	Day rate can be higher; off-peak times vary by region.
Green/Renewable	Backed by renewable generation or certificates (REGOs).	Lower carbon footprint and ethical preferences.	Tariff terms vary; check actual sourcing and premium.
Prepayment (Pay-As-You-Go)	Top up in advance via key/card/smart; helps budget.	Tighter control of spend.	Rates may differ; risk of self-disconnection if not topped up.

How the Ofgem Price Cap Affects Your Bills

The Ofgem price cap limits the unit rates and standing charges suppliers can charge typical households on standard variable tariffs. It reflects underlying costs like wholesale energy, networks, policy and operating costs. The cap is reviewed periodically, typically quarterly.

The cap does not apply to fixed or special tariffs — those can be above or below the cap.
Your bill depends on how much you use: use less, pay less.
Regional costs and payment method can affect the rates you see.

How to Choose the Best Energy Tariff for Your Home

Every household is different. Use these tips to narrow down the best-value deal for your circumstances.

1) Know your usage

Check your latest bill for annual usage in kWh for electricity and gas. If you’re unsure, we’ll estimate from household size and heating type.

2) Decide on certainty vs flexibility

Prefer predictable bills? Consider a fixed tariff. Want freedom to switch if prices fall? A standard variable or tracker might suit.

3) Consider a smart meter

Unlock time-of-use rates, accurate bills and energy insights to help reduce waste. Installation is usually free from your supplier.

4) Check fees and extras

Look for exit fees, green add-ons, EV charging benefits, or rewards. Calculate the whole-year cost, not just the unit rate.

Frequently Asked Questions about UK Energy Tariffs

What are the latest domestic energy tariffs in the UK?

Tariffs change regularly and vary by region, usage and supplier. The most common options include standard variable tariffs (subject to the Ofgem price cap), fixed-rate deals, tracker/indexed tariffs, smart time-of-use tariffs, Economy 7/10 and prepayment tariffs. Compare live offers for your postcode and usage to see accurate prices.

Should I fix my energy tariff now?

Fixing can provide price certainty and protect against future rises. However, if market prices fall, you could pay more than a variable alternative. Consider your risk tolerance, contract length and any exit fees. Comparing both fixed and variable deals for your usage is the best approach.

Are smart tariffs cheaper?

They can be if you shift usage to off-peak times (overnight or weekends). Households with EVs, heat pumps or storage heaters often benefit most. If you mostly use energy at peak times, a flat or fixed tariff may suit better.

What affects my standing charge and unit rates?

Wholesale energy costs, network charges, environmental and social policy costs, supplier operating costs, your region, and payment method can all affect the rates you pay.

Will switching interrupt my supply?

No. Your gas and electricity are delivered through the same networks. Only your billing company changes. Meter readings are shared to ensure a smooth handover.

How long does switching take?

Most switches complete in 5–15 working days, including any cooling-off period. If you have a smart meter, it usually continues to work as normal after the switch.

What information do I need for a quote?

Your postcode, current supplier/tariff, payment method and annual usage (kWh). If you don’t know your usage, we can estimate it based on your household.

Can tenants switch energy supplier?

Yes, if you are named on the energy bill. Check your tenancy agreement. Even if your landlord manages the energy, you can still discuss switching to a better value tariff.
