Should I fix my energy deal now?

It depends on the price you can lock today. If a fixed tariff’s unit rates and standing charges are close to or below your current standard rates, it buys certainty. Martin Lewis urges a quick check now, given the wholesale spike. Use your actual kWh usage to compare and confirm exit fees.

How could wholesale gas prices affect the Ofgem price cap?

The cap reflects forward wholesale prices over a defined observation window plus other costs. A brief spike may have little impact, but multi-week strength can lift allowed unit rates later. If recent gains persist into spring, the cap after June could rise versus earlier forecasts. If prices ease, pressure lessens.

What should I check before switching energy deals?

Compare unit rates and standing charges, not just the monthly payment. Check contract length, exit fees, any smart meter terms, and whether the offer is fixed or variable. Use last year’s kWh usage to model costs. Confirm direct debit rules, bill credits, and any perks that might affect your real price.

Will higher gas prices change UK inflation and interest rates?

Yes, if the rise lasts. Higher energy costs can lift CPI with a lag and squeeze household budgets. That can slow Bank of England rate cuts and keep gilt yields firmer. Watch inflation swaps, utilities’ guidance, and retail sales. A short spike matters less than a sustained period of elevated prices.
