How to Choose the Best Energy Supplier

When you compare UK energy suppliers, don’t just look at price. The best ones offer reliable customer service, good value, and support for renewable energy and new tech.

Customer Service and Satisfaction

Customer service matters, especially when you need help with your bill or have a complaint. Top companies usually have high customer satisfaction scores and get fewer customer complaints.

Quick replies, friendly staff, and easy ways to get in touch can make a huge difference. When you pick a supplier, check out reviews that show customer score and satisfaction—these reveal how the company handles real issues.

Companies proud of their support often share details about their customer teams and response times. Suppliers rated as a Recommended Provider have to score at least 70% in customer reviews, so you know lots of households trust them.

Energy Prices and Tariffs

Energy prices and tariffs can swing a lot between providers. Most people want value for money, so comparing what’s out there makes sense.

Look for simple tariffs, no hidden fees, and deals that match how you use energy. Some suppliers offer fixed rates so you pay the same each month, while others let prices move with the market.

You can use comparison tools or the Which? energy company reviews to see who’s got the best energy supplier deals right now. Watch for exit fees if you move or want to switch plans—always read the fine print so you don’t get caught out.

Renewable Energy

More people want renewable energy and like suppliers investing in new ways to generate power. If you pick a provider with green tariffs, your electricity comes from wind, solar, or hydro sources.

Many top companies highlight their commitment to renewables and might offer extras like carbon offset schemes or tips for saving energy. Some suppliers stand out for innovation too—maybe they use smart meters, let you track usage in real time, or have handy apps for managing your account.

If you care about sustainability and tech, check for companies leading in those areas and showing their progress online.

Which energy company has the best reviews in 2025?

When you compare UK energy suppliers, focus on customer ratings, pricing, and how companies handle complaints. Trust scores, wait times, and honest feedback all matter if you want the best provider for your needs.

Octopus Energy

Octopus Energy gets noticed for strong customer service and satisfaction. On Trustpilot, Octopus keeps a high score, with most users praising its clear billing, helpful staff, and quick replies.

British Gas

British Gas is one of the oldest and biggest energy providers in the country. The company gets mixed reviews and sits around the middle on Trustpilot.

Customers often mention reliable service and strong phone support, though some struggle with billing or complicated tariffs. Centrica owns British Gas, and its size means it can offer lots of plans and competitive prices for fixed and variable tariffs.

The brand is known for extras like boiler cover and smart home add-ons. Call response times have improved, but British Gas still gets some criticism over complaint handling and customer commitments.

For many, the brand’s long history and broad coverage outweigh concerns about satisfaction scores, especially if you want established support.

Trustpilot reviews are mixed. Some customers like the steady supply and range of tariffs, but others worry about slow customer service.

Tariffs and Deals Explained

You’ll find several types of energy tariffs in the UK. Each one has its quirks that affect how much you pay and how predictable your bills are.

Fixed vs Variable Tariffs

A fixed tariff locks in your unit rates for a set period, usually 12 to 24 months. Your gas and electricity prices stay the same, no matter what happens in the wholesale market.

Fixed deals are popular if you want to dodge sudden bill hikes, especially when things feel unpredictable. But if prices drop, you won’t get those savings until your contract ends.

A variable tariff lets your rates change. If your supplier drops prices, your bill could go down, but if prices rise, so will your costs.

Variable tariffs often follow the government’s price cap. They’re flexible and rarely have exit fees, so you can switch providers without much fuss.

Check if you’re on a fixed or variable deal—it changes how your bills react to the market. You can compare the pros and cons of each using tools like MoneySavingExpert’s energy comparison.

Dual Fuel and Green Tariffs

A dual fuel tariff means you buy both gas and electricity from one supplier. This can get you discounts for combining both into a single bill.

Managing just one account makes life a bit simpler. Some companies throw in perks like loyalty rewards or lower standing charges if you go dual fuel.

Green tariffs are for anyone wanting to cut their carbon footprint. These deals match all or some of your energy with renewables—think wind or solar.

Some suppliers, like Octopus Energy, get recommended for their green plans. The unit price for green tariffs can be a touch higher, but honestly, a lot of people feel it’s worth it for the planet.

Here’s a quick table showing what you get:

Tariff Type	Key Feature	Typical Benefit
Dual Fuel	One bill for gas and power	Simplicity, discounts
Green Tariff	Renewable energy supported	Eco-friendly, transparent

Tracker and Pay As You Go Options

Tracker tariffs follow wholesale energy prices, so your rates change regularly. If market prices fall, your bills can drop too, but if they spike, you might pay more.

These tariffs aren’t that common, but they suit people who want to follow the real-time market and don’t mind some risk. Look for tracker deals from companies that clearly explain how their adjustments work.

A pay as you go meter works differently from regular billing. You top up your meter—kind of like a mobile phone—before you use gas or electricity.

This method is handy if you want tight control over your spending. But pay as you go tariffs usually have higher standing charges and unit rates, so they’re often pricier over time.

If you’re struggling with bills, some suppliers offer help for pay as you go customers. Tools like Uswitch’s comparison can point you to suppliers with good support and rates.

Switching Energy Supplier and Saving Tips

Switching to a new energy supplier can help you find better value, especially with the energy market all over the place lately. Comparing tariffs and using smart energy-saving tricks can really cut your bills.

Switching Process and Consumer Protection

Switching suppliers is pretty easy these days. Most changes finish in just a few days, and your power stays on the whole time.

You don’t need to call your old supplier—your new one handles it all, either online or over the phone. Companies regulated by Ofgem stick to strict rules to protect you during the switch.

If you’ve got debt and a prepayment meter, you have extra rights. Your data stays protected, and you can complain if something goes sideways.

Energy comparison platforms can help you find the best deals. Groups like Citizens Advice have guides and support if you need it.

There’s no charge for leaving unless you’re under a fixed-term contract with exit fees.

Comparing the Cheapest Energy Deals

It’s smart to compare tariffs often, especially with prices bouncing around. Use trusted energy comparison sites to check offers from big names and smaller firms.

Look at standing charges, unit rates, and contract terms for a clearer picture. Well-rated providers are worth a look.

For 2025, Octopus Energy, Utility Warehouse, and 100Green have topped customer polls.

Online tools usually let you enter your postcode and usage for quick results. Watch for small print—minimum contract lengths and early exit fees can sneak up on you.

Energy Saving Tips and Innovations

Cutting your energy use matters just as much as finding a cheap tariff. Simple stuff like turning down your thermostat by 1°C, using LED bulbs, and switching off appliances helps.

Try smart meters or battery storage to track and manage your use. Some suppliers now have time-of-use tariffs, so you pay less at off-peak times.

Home batteries can store solar power for later, which lowers your grid use and bills. Staying up to date with the latest advice and tech can help you save even more.
