Intro

With the UK’s push toward net zero emissions, gas boilers are slowly being phased out. But what should you replace them with?

Let’s explore three real alternatives—two already in use—and what might be the right fit for your home.

1. Heat Pumps – A Smarter Way to Heat

Heat pumps work by pulling heat from the air and compressing it—just like your fridge, but in reverse. They run on electricity and offer a clean, low-carbon alternative to gas.

• ✅ Lower emissions
• ✅ Grants available to cut upfront cost
• ✅ Similar running costs to traditional boilers

2. Hydrogen Boilers – Not Yet, But On the Horizon

Hydrogen boilers aren’t available yet—but they’re being tested. The UK may start blending hydrogen into the gas grid by 2028, and all Insignia boilers are already hydrogen-blend ready.

• 🔄 Works like a standard boiler
• 🌍 Lower carbon impact
• 💷 Similar cost to traditional gas boilers

For now, hydrogen is more of a “future-ready” feature than an option to install today.

3. A-Rated Gas Boilers – Still the Best Option Today

Until hydrogen or heat pumps become widespread, your best bet is to upgrade to an A-rated boiler. Every boiler we install at Insignia is energy-efficient and future-proof. Pro tip: Save even more by using energy smarter—like turning off standby electronics or unplugging unused chargers.

• 🔋 Lower energy bills
• ♻️ Better for the environment
• 🏠 Works with most UK homes
• 🔧 Ready for a hydrogen blend when the time comes
