SHORT ANSWER
Compare total annual cost, not headline rates: unit rates and standing charges applied to your own usage. The market scan below ranks live fixed tariffs for an average dual-fuel home paying by monthly Direct Debit, refreshed hourly and hidden if the latest prices are more than two hours old. Your postcode, meter and real usage can change the order, so check your own tariff before you switch, speak to your supplier or keep monitoring.
WHAT YOU COULD SAVE
Switching or fixing at the right time can reduce your annual energy cost.
Energy savings depend on your tariff, usage, region, payment method and whether you are on a fixed or variable deal. Some households can save more than £200 a year by shopping around for a cheaper fixed tariff, especially when market prices move below the default tariff cap.

WHAT DRIVES YOUR BILL
Your energy bill has three moving parts.
Some change with how you use energy. Others change with the deal you are on. Understanding the difference helps you know what to check.
Your usage
Your usage
How much gas and electricity your home uses.
Usage changes with your home, habits, season and appliances. It affects your bill, but it is not always the fastest thing to change.
Your rates
Your rates
What you pay per unit of energy, plus standing charges.
Your tariff sets these rates. If rates change, your bill can rise even when your usage stays similar.
Your deal
Your deal
The tariff, contract length, exit fees and renewal timing you are on.
This is the part worth reviewing regularly, especially when your tariff ends, prices rise or better options appear.

Compare the best average energy deals
Taupia agents keep scanning available energy tariffs and ranking the options that could reduce bills. This preview shows a dual-fuel average-household view before your own bill, usage and address refine the result.
Agent monitoring
Our agents keep checking the market so users can be alerted when a stronger fixed, tracker or non-SVT option appears.

Average-household view. These examples use average dual-fuel consumption. Your best tariff can change with postcode, region, meter type, standing charges, unit rates and your real kWh usage.
Same usage, side by side
On the same average-household usage, a capped standard variable tariff costs £1,766 a year. The default tariffs of 6 suppliers in this scan share that price.
The cheapest fixed tariff here, Sainsburys Energy Fix and Save 24m v11 from Sainsbury's Energy, costs £34 a year more, so at today's prices a fix costs more than staying on a capped tariff. The cap can still change every three months.
Both figures come from this scan, so they use the same usage. Ofgem's headline cap figures assume a different typical household. See Ofgem's cap figures

COMMON OVERPAYING MOMENTS
Overpaying can happen when one of those parts changes.
A fixed deal can end. Variable prices can rise. Better options can appear. These are the moments worth checking.
01

Open the renewal email action planWHEN THE BILL ARRIVES
The first sign is often a higher bill.
A bill spike can come from usage, tariff changes, standing charges, estimates or billing catch-up. The key is knowing which part changed.
More usage
Cold weather, working from home or new appliances can increase consumption.
Higher unit rates
Your tariff rate can change, especially if you are on a variable tariff.
Standing charges rise
Fixed daily charges can increase even if your usage stays steady.
Estimated readings
Supplier estimates can make a bill look wrong or unexpectedly high.
Billing catch-up
If previous bills were estimated too low, a later bill may include the difference.
WHAT YOU CAN DO
You may not need to switch. But you do need to check.
Start by finding what changed. Then decide whether to switch, speak to your supplier or keep monitoring.

AFTER YOU SWITCH
What happens after you switch energy supplier?
You will not lose your gas or electricity. Your supply continues as normal while your old and new suppliers handle the transfer.
01
Supply continues
Your gas and electricity are not disconnected during the switch.
02
Switch date confirmed
Your new supplier tells you when your new tariff starts.
03
Meter readings may be needed
Opening and closing readings help keep bills accurate.
04
Old account closed
Your previous supplier sends a final bill or refund.
05
New tariff starts
Your new provider bills you on the agreed rate and payment terms.
ENERGY MARKET UPDATE
News that can affect your energy bill
Price caps, supplier rate changes and tariff updates can change what you pay. Use this update to understand what changed and whether your current tariff is worth checking.
October 2026 cap: confirmed 26 August 2026, 3.9% rise
Ofgem confirmed the October to December 2026 cap on 26 August 2026, and it applies from 1 October. On equivalent consumption, annual bills rise from £1,862 to £1,935 (+£73/year, or 3.9%) on the like-for-like basis, or from £1,663 to £1,723 on Ofgem's own current basis. Most of that is gas: gas bills rise about 8%, while homes with no gas see under 1%. Ofgem confirms the January to March 2027 level on 25 November 2026. If you are on a variable tariff, it is worth comparing now.
FAQs
Energy bills, price rises and switching: common questions
Am I overpaying after my fixed deal ended?
Often, it is worth checking. If your tariff moved to an SVT, compare your unit rate and standing charge against current fixed options so you can see whether your new default price is still competitive.
What is a Standard Variable Tariff (SVT)?
An SVT is the supplier's default tariff after your fixed term ends or when no new deal is chosen. Prices can change, and the rate is commonly above competitive fixed offers.
How do I compare energy prices when my contract is ending?
Start with your current bill, not generic quotes. Compare unit rates, standing charges, and contract terms against live options. This shows whether switching now or waiting is the better move.
I got a renewal email. What should I do first?
Check the new proposed tariff against current market options before accepting. A fast comparison usually tells you within minutes whether renewing would mean overpaying.
Will my gas or electricity be cut off when I switch?
No. Your energy supply is never interrupted. The same pipes and wires deliver your energy regardless of who supplies it. Switching is an administrative change, and your lights stay on throughout.
Can I compare if I am still in a fixed contract?
Yes. Compare at any point, including mid-contract. Check your current deal's exit fees against the potential saving to decide whether to switch now or wait until the fee window closes.
How long does switching energy supplier take?
Switching takes up to 5 working days. Taupia handles cancellation, new registration, and meter reading handover. You approve the switch and Taupia does the rest.
Can I switch energy supplier if I have a smart meter?
Yes. Smart meters work with major Great Britain suppliers. In rare cases, a first-generation smart meter may temporarily lose smart functionality after switching until the new supplier activates it remotely.
Which locations are covered for energy switching?
Taupia's energy comparison and switching journey is available across Great Britain: England, Scotland, and Wales.
I just became the bill owner at a new address. Can I still compare?
Yes. Once the bill is in your name, you can compare immediately. This is useful for first-time renters and people who have just moved home.
How does Taupia compare with traditional comparison sites?
Traditional comparison tools are usually one-off journeys. Taupia is designed to keep managing your bills after the first switch so you do not have to restart from scratch every time.
| Feature | Taupia | Traditional tools |
|---|---|---|
| Ongoing bill management | Continuous monitoring over time | One-time comparison journey |
| Contract and renewal tracking | Automatic reminders before contracts end | Requires manual re-check |
| Personalised bill insights | Guidance based on your actual bill | Generic FAQs and help pages |
| Household overview | Combined monthly view across all bills | Separate journeys, no unified view |
| Switching | You approve it inside the app | Redirect to provider website |
| After switching | Monitoring continues automatically | Journey ends after switch |
Is this only for energy, or can I track other bills too?
Taupia handles energy, broadband, and mobile from one account. The loyalty tax pattern is similar across all three.
How does Taupia make money if it's free?
When you approve an energy switch through Taupia, the new provider pays a referral commission after it completes. Taupia retains that commission to keep the core product free.
