How to Fight the July 13% Energy Price Hike Before Winter

On July 1st, 2026, the UK energy price cap increased by a painful 13%, pushing the typical annual energy cost up to £1,862. With winter fast approaching, homeowners across Sussex and Surrey are looking for urgent ways to protect their wallets.

If you felt the sting of last winter's heating bills, this new hike is the last thing you want to hear. However, there is good news: you don't have to freeze to save money. By taking action now, before the cold weather truly sets in, you can completely offset this 13% increase through smart, highly efficient home heating upgrades.

Here are the top three ways our Gas Safe engineers are helping local homeowners slash their energy bills right now.

1. Upgrade to a Smart Thermostat

Traditional thermostats are notoriously inaccurate. If they are off by just 1 degree, it can add up to 10% to your annual heating bill. Smart thermostats learn your home's thermal profile, track the weather, and allow you to control your heating directly from your phone.

More importantly, features like "Geofencing" ensure your boiler turns off automatically when the last person leaves the house, and starts warming up just as you are on your way home. It guarantees you are never paying to heat an empty house.

2. Powerflush Your Central Heating System

Did you know that a dirty heating system can force your boiler to work 15% harder just to heat your radiators? Over time, black sludge (magnetite) builds up inside your radiators and pipes. This sludge blocks the flow of hot water, creating cold spots at the bottom of your radiators and putting immense strain on your boiler's pump.

A professional Powerflush involves pumping cleaning chemicals through your system at high velocity to blast out the sludge. The results are immediate:

• Radiators heat up significantly faster.
• Cold spots are eliminated.
• Your boiler doesn't have to work as hard, saving you gas and extending its lifespan.

3. Replace an Old Boiler with an A-Rated Model

If your boiler is over 10-15 years old, it is likely a non-condensing G-rated boiler. These old units are notoriously inefficient—often operating at just 60% efficiency. That means for every £100 you spend on gas, £40 is literally disappearing out the flue pipe as waste heat!

By upgrading to a modern, A-rated condensing combi boiler, efficiency jumps to 94% or higher. For a typical semi-detached home in Crawley or Horsham, jumping from a G-rated to an A-rated boiler can save you over £300 a year on your gas bills—more than enough to wipe out the recent 13% price cap hike entirely.
