Latest Recommendations (February 2026)
As of February 2026, the advice has shifted from “stay put” to “active comparison.”
The current Energy Price Cap (Jan 1 – Mar 31, 2026) is set at £1,758 a year for a typical household. However, analysts predict this will fall by around 6-8% in April 2026 (to roughly £1,650) due to falling wholesale costs and government policy changes removing certain levies from bills.
Martin’s current stance:
- Variable Tariffs: If you do nothing, your rate will likely drop in April.
- Fixed Deals: There are now fixed tariffs emerging that are already cheaper than the April forecast. If you can find a fix below £1,650, Martin suggests it is worth considering to lock in certainty and beat the coming price cap.
Who does he mention?
- Octopus Energy: Remains the “best of the big names” for service. They often offer competitive “tracker” tariffs and fixes that undercut the cap.
- E.ON Next: Often highlighted recently for having some of the cheapest standalone fixed tariffs for new customers.
- British Gas / OVO: Occasionally launch competitive fixes for existing customers, so check your account offers.
Important Note on the “April Cut”: The government announced a £150 cut to energy bills starting April 2026 (by shifting green levies to general taxation). Most suppliers (including Octopus, British Gas, and E.ON) have confirmed that this discount will apply to both variable and fixed tariffs.

Criteria for Choosing Providers
Martin Lewis uses specific criteria when he recommends energy providers. Here’s what he looks at:
- Price: Is the fixed tariff cheaper than the projected April price cap?
- Customer Service: Do customers get quick, helpful support? (Octopus consistently ranks #1 here).
- Fixed vs Variable: Does the provider offer fixed prices that beat the market trend?
- Financial Stability: Is the company solid enough to stick around?
He looks for companies with a track record of fairness. Weigh these factors yourself when you compare providers—they directly affect your bills and service.
How Recommendations Are Updated
Martin Lewis updates his recommendations as new deals and market shifts come up.
- January 2026 Update: The Price Cap rose slightly to £1,758.
- Upcoming April 2026 Update: The Cap is expected to drop. Martin reviews whether fixing now is better than waiting for the variable rate to drop later.
He checks tariff changes, feedback from thousands of users, and any new government rules (like the 2026 levy changes). This keeps his tips fresh and helps you react quickly so you don’t miss out on better rates.
How Martin Lewis Evaluates Energy Companies
Martin Lewis keeps things practical, focusing on clear, evidence-based factors when he reviews energy providers. His picks rely on costs, customer experiences, and whether companies genuinely offer greener choices.
Comparing Tariffs and Pricing
He advises you to look closely at the costs of different energy tariffs. Check both fixed and variable deals, since rates often shift with the market.
Comparison websites make it easier to see prices from different suppliers. He often highlights special offers, like sign-up bonuses or referral deals. Octopus, for example, offers referral incentives that can save you money when you switch.
Always read the terms to know how long the deal lasts and if there are exit fees. Martin also tracks energy price caps and market changes. If a price hike is coming, he might suggest switching or locking in a deal before new rates kick in.
Customer Service Performance
Customer service ratings really matter in Martin Lewis’s evaluations. He prefers companies with quick response times and helpful call centres.
Getting timely help with billing or complaints can make a big difference. He often looks at annual surveys and independent reviews to find reliable providers. If a company gets a lot of complaints or bad reviews, he’ll flag that.
Many people also want good online account management. Martin checks if companies have easy-to-use apps or websites, so you can submit meter readings, check usage, or change plans without a headache.
Green and Renewable Options
Martin Lewis pays attention to a company’s green credentials. He checks if they offer 100% zero-carbon electricity tariffs or invest in projects that support cleaner energy.
He highlights companies making real efforts to help the planet—not just using green marketing. Some go further by planting trees, supporting solar, or letting you offset gas use.
When he evaluates these options, Martin looks for evidence. He suggests you check the company’s fuel mix and see if renewable claims actually stack up. Transparent info makes it easier to pick a provider that fits your values.
Alternatives Suggested by Martin Lewis
Martin Lewis often says the best energy choice depends on your habits and what’s happening in the market. He gives advice on comparing tariffs and timing your switch to get the most out of your money.
Fixed Versus Variable Tariffs
A fixed tariff locks in your energy price, usually for 12 months. You know what you’ll pay each month, even if market prices jump. That’s great if you want stability.
A variable tariff changes with the market, often following the regulator’s price cap. Sometimes, especially when prices are falling, the variable option might turn out cheaper.
Martin Lewis explains that during high-price periods, fixed deals can cost more than variable ones. He suggests sticking with the price cap unless you find a fixed deal that’s cheaper over the year than your current rate.

The “Fix” Calculation for Feb 2026
- Variable (Price Cap): Currently £1,758/yr. Will likely drop to ~£1,650 in April.
- Fixed Deals: Some fixes are available now for ~£1,600 – £1,630/yr.
Martin’s Advice: If you find a fix below £1,650, you will likely save money over the next year compared to staying on the variable rate, plus you get protection if global events send prices shooting back up in late 2026.
| Tariff Type | Price Changes | Stability | Best For (Feb 2026) |
|---|---|---|---|
| Fixed | No | High | People who want to beat the April Cap and lock in certainty. |
| Variable | Yes | Low-Medium | Those willing to wait for the April price drop. |
Switching Strategies
Switching suppliers can save you money, but timing is key. Martin Lewis recommends waiting for new fixed tariffs when the market looks good or when regulators drop the price cap.
He also says to compare deals regularly, since offers change all the time. Use a free online comparison tool to check market-wide deals and see if switching could help you save.
Look at things like exit fees and contract length before you switch. Martin sometimes highlights suppliers with good customer service, like Octopus Energy, but he reminds you not to get stuck on brand names.
Focus on price, tariff type, and contract details so you get what works for you. If you’re not sure, just wait for an update from reliable sources like MoneySavingExpert.
