Why Families Are Leaving British Gas

British Gas is the UK's largest energy supplier — but that size comes with a cost. As a legacy "Big Six" provider, British Gas charges standard variable tariffs that sit at or near the Ofgem price cap. That means if you haven't actively switched to a better deal, you're almost certainly overpaying.

Here's what's happening right now:

  • British Gas's parent company Centrica posted record profits of £3.3 billion — while raising your bills
  • Their standard variable tariff is consistently one of the most expensive on the market
  • Loyalty doesn't pay — long-term British Gas customers pay more than new customers
  • Exit fees and confusing tariff structures keep you locked in longer than you need to be

"I'd been with British Gas for 11 years. Never thought to switch because I assumed they'd reward loyalty. They didn't. SaveFirst found me £73 a month in savings across all four bills. I'm genuinely angry I didn't do this years ago."

Common Questions About Switching From British Gas

No. British Gas is the UK's largest energy supplier but rarely the cheapest. As a Big Six provider, their standard variable tariff typically sits at or near the Ofgem price cap. Most households can save £300–700 per year by switching to a more competitive provider. A free SaveFirst audit will show you exactly how much you could save.

With SaveFirst, you don't have to do anything. Send us your current British Gas bill (a photo on WhatsApp is fine), and we handle the entire switch — no phone calls to British Gas, no cancellation forms, no paperwork. Your supply is never interrupted during the switch.

No. British Gas HomeCare and boiler cover are separate products from your energy supply. Switching your energy away from British Gas does not affect your boiler cover, home insurance, or any other British Gas product you may have.

Yes, completely free. We're paid by the provider when you switch — you never pay us anything. If we can't save you money, nobody pays anything and you stay exactly where you are.

The Bottom Line

British Gas isn't a bad company — but they're not the cheapest, and they're not looking out for your wallet. Every month you stay on their standard tariff is money you don't need to spend.

A free SaveFirst audit takes 2 minutes and costs nothing. If we can't save you money, you stay with British Gas and nothing changes. If we can — and for most families we save £56/month or more — you keep every penny of those savings.

There's literally no downside. The only risk is waiting another month.
