How homeowners can fight back against rising energy bills

New research from Yopa warns that millions of homeowners are set to be hit with a 14% jump in energy bills this summer, wiping out recent savings and piling fresh pressure on household finances.

In response, Yopa has analysed which home improvements are most effective at reducing energy use, looking at both the typical savings delivered and how quickly homeowners can expect to recoup the cost.

Yopa’s analysis of historical and forecast energy price cap data shows that: –

• Between Q3 2025 and Q1 2026, the average energy price cap rose by £38 to sit at £1,758.
• However, households have since been afforded a brief respite, with the cap falling to £1,641 in Q2 2026. But this relief is expected to be short lived, with the cap forecast to climb by 14% to £1,870 from 1st July.
• And the pressure may not stop there. Early projections from British Gas* suggest the cap could climb again to £1,895 in Q4 2026.

The bottom line? Households could soon be paying significantly more again,  just as many thought the worst was over.

How to cut your energy bills. And what’s actually worth it

With costs rising again, making your home more energy efficient can soften the blow, but not all upgrades are created equal. Here’s what delivers the quickest return:

Fast payback wins:

Smart thermostat

• Cost: £225 | Annual saving: £164
• Pays for itself in just 1.4 years

Energy-saving light bulbs

• Cost: £135 for 30 lightbulbs | Annual saving: £90
• Payback: 1.5 years

Mid-term savings:

Loft insulation

• Cost: £944 (270mm of quilt insulation)| Annual saving: £260
• Payback: 3.6 years

Boiler upgrade

• Cost: £3,000 | Annual saving: £328
• Payback: 9.1 years

Long-term investments:

Solar panels

• Cost: £6,100 | Annual saving: £270
• Payback: 22.6 years

Double glazing

• Cost: £4,200 (£420 per window fitted) | Annual saving: £150
• Payback: 28 year

Verona Frankish, Chief Executive Officer at Yopa, said:“People up and down the country are going to be understandably worried to see the energy price gap rising once more, just as we thought things were settling down.

Of course, those of us who are going to be most impacted by rising bills are also the least likely to have thousands of pounds available to install solar panels or a brand new boiler, but there are things that we can do to increase our home’s energy efficiency that don’t require much upfront investment at all.

So it’s good to know that the more affordable options, such as smart meters and energy saving lightbulbs deliver good, tangible savings over a short period of time. They may seem like changes too minor to make a difference, but they do, which means they’re definitely worth sorting before July’s cap increase.”
