When should I lock in my energy rates for winter 2026?

Most fixed-term tariffs have an exit fee for early termination, but many suppliers now offer flexible deals or waive exit fees if you switch through approved channels like Energy Plus. Always check the terms of your current contract before switching.

Why Lock In Energy Rates Early for 2026?

With energy markets in the UK expected to remain unpredictable, homeowners looking for budgeting certainty should consider locking in energy rates well ahead of winter 2026. Fixing your gas and electricity tariffs now can:

Use trusted comparison tools to find suppliers offering two- or three-year fixed deals at competitive prices. Fixing now reduces exposure to short-term price surges.
2. Act Before the Price Cap Changes
The Ofgem price cap is updated quarterly. Switching just before an anticipated rise can help you lock in now-available low rates for longer.
3. Bundle Gas & Electricity for Deeper Discounts
Dual-fuel offers are often cheaper and come with switcher incentives or cashback.

Step-By-Step Guide: How to Lock In the Lowest Home Energy Rate

Review your current tariff: Check if you’re on a standard variable or fixed deal. Find out when your contract ends to avoid early exit fees.
Run an energy comparison: Use the Energy Plus Energy Comparison Tool or similar trusted site. Enter your postcode and usual energy usage for accurate cost forecasts.
Filter for fixed-rate deals: View contracts that extend through winter 2026, favouring those with low daily standing charges and competitive unit rates. Watch for exit fees or hidden charges.
Select and apply online: Switching through a trusted online provider is usually fast, secure, and offers exclusive deals not available direct.
Submit your meter readings: Smooth switching by providing accurate figures for your final and first bills with the new supplier.

Tip: Early movers often get the best rates! Many suppliers release affordable fixed deals for proactive switchers.

Is a Fixed Energy Tariff Right for My Home?

Fixed tariffs aren’t for everyone. They suit households seeking bill predictability and less hassle. If you expect energy prices to fall, a variable deal could save money. However, during times of uncertainty (like winter 2026), a fixed plan offers:

Guaranteed unit rates for the contract length (no mid-contract increases)
Peace of mind for budgeting during winter's peak usage
Flexible options upon contract end to switch again or go variable

Top Tips for Getting the Best Energy Deal for Winter 2026

Switch in summer or early autumn: Suppliers tend to launch most attractive offers before winter spikes in demand.
Avoid automatic renewals: Standard variable tariffs can be much costlier – always shop around before your deal ends.
Sign up for tariff alerts: Many sites (including Energy Plus) offer free notifications when new fixed deals go live.
Boost your credit rating: Top deals sometimes require a credit check, so a high score may unlock even cheaper rates.
Consider renewable tariffs: Many green fixed-rate deals rival ‘regular’ tariffs on price and help future-proof your home against fossil fuel volatility.
