Why switch energy?
With gas and electricity prices rising significantly in recent years, the energy market is showing signs of stabilisation after a prolonged period of volatility. As we approach the end of 2025, consumers are bracing for yet another price rise, but are still in a better position than they were a couple of years ago, as savings can be made by comparing tariffs and switching suppliers.
- New fixed tariffs: Most energy suppliers have reintroduced fixed-rate plans, offering potential savings compared to the price cap.
- Competitive deals: After a prolonged absence, competitive deals are slowly re-entering the market, providing more options for consumers.

Switch Now to Beat the Price Cap
From October 1st to December 31st, 2025, the energy price cap is set at £1,755 for the average household, a 2% increase from the previous cap of £1,720.
However, while competitive deals are slowly re-emerging in the market after record high levels over the last few years, saving money on your household energy bills isn’t as simple as finding a cheaper tariff and switching. While that’s certainly the first step, long-term savings remain uncertain as the market continues to fluctuate.
As your gas and electricity bills will vary based on your actual energy consumption, you need to consider reducing your own household’s usage with energy-saving measures. These can range from simple changes such as switching off all devices and turning off lights when not in the room to considerable investments, such as home solar panels or heat pumps.
While switching to a cheaper fixed tariff can help you to save money both in the short term and long term, we also advise you to regularly keep up to date with fluctuations in the market and to monitor your usage so that you can identify where to make cost-saving measures.

What to look for in an energy supplier
When comparing energy suppliers, it's important to consider the following aspects to ensure you're making the best choice for your needs. By carefully weighing these factors, you can make a more informed decision.
Start Comparing1. Price
Look at both the unit rate and standing charge, ensure it’s below the price cap, and compare with similar tariffs.
2. Tariff type
Fixed rate for peace of mind, or variable rate for potential savings if prices fall. Choose what suits your risk appetite.
3. Customer service
Check online reviews and satisfaction ratings. You want issues resolved quickly and efficiently.
4. Green credentials
Check the fuel mix for renewable sources or opt for a specific green tariff to support sustainable initiatives.
5. Contract length & Exit fees
Check for exit fees on fixed tariffs. Ensure the contract length aligns with your plans.
What types of energy tariffs are available?
Fixed Rate Energy Tariffs
A fixed rate tariff locks in the price per unit of gas or electricity for the duration of your contract, which is typically between one and two years. While your monthly bills will depend on your actual energy usage, the unit price remains the same, so you'll be protected from any price increases in the wholesale market.
However, you won't benefit if prices drop. Generally, fixed rate tariffs offer lower prices along with stability and predictability.
Variable Rate Energy Tariffs
With a variable rate tariff, the price you pay per unit of energy will change based on wholesale price fluctuations. If wholesale energy prices rise, so will your bills, but you’ll pay less when the market drops.
The most common type are default or standard variable tariffs. These are typically the most expensive, yet many remain on them if they haven't switched in over two years.
Dual Fuel Tariffs
Combining gas and electricity under a single supplier. Often results in cost savings and easier management.
Prepayment Tariffs
Pay in advance and top up. Typically higher rates, recommended only to manage debt or budgeting strictly.
Economy 7 Tariffs
Different rates for day and night. Beneficial for those using lots of energy at night (e.g. EV charging).
Renewable Tariffs
Electricity from renewable sources. Now very competitive, allowing you to reduce carbon footprint and bills.
Should you switch to a green energy supplier?
Apart from reducing your carbon footprint, there are many benefits to switching to a green energy supplier. Renewable energy is now much more competitive, meaning you can save money while helping the environment.
With dozens of suppliers focusing on renewable energy, it’s easy to find one. Simply take a look at their fuel mix.
Other ways to save energy at home
Switching is just the first step. Lower your consumption and improve efficiency for the biggest savings.
Solar panels
Generate your own electricity. Significant upfront cost but offers long-term savings and independence from grid prices.
Heat pumps
Efficient alternative to boilers. Can be expensive to install but high efficiency lowers long-term bills.
Boilers
Upgrade old boilers to modern efficient ones. Cheaper than heat pumps with quicker ROI.
Double glazed windows
Enhance insulation and heat retention. Keeps heating bills low especially in winter.
Insulation
Loft, wall, or floor insulation prevents heat loss. Drastically improves efficiency.
Switching Business Energy
Whether you run a SME or a large organisation, comparing business tariffs can lower outgoings. The UK business market has key differences:
- No price cap: Rates are set entirely by the supplier contract.
- Extra charges: VAT (often 20%) and Climate Change Levy.
- Longer contracts: Up to five years, making locking in rates crucial.
- Tailored rates: Quotes depend on business size, usage, and industry.
