April Energy Cap: Maximise Savings with Insulation
Why the Energy Price Cap Is Going Down in April — and How Insulation Can Make the Most of It
Good news for UK households: from 1 April to 30 June 2026, the Ofgem energy price cap is set to fall by around 7 % compared with the first quarter of the year. This means a typical dual fuel household paying by direct debit will see the cap drop to about £1,641 per year — roughly £10 a month in savings, compared with the cap that ran from January to March.
While this is great news on its own, it’s worth understanding what this actually means — and how you could save even more through smarter choices like insulation.
The energy price cap isn’t a cap on your total bills. Instead, it limits the maximum price per unit of gas and electricity that energy suppliers can charge customers on default tariffs. Because the cap limits prices but not usage, households that use more energy will still see higher bills — even with the lower cap. Whilst the April drop is welcome, analysts are already forecasting that the cap could rise again later in the year due to global wholesale price volatility. That’s where energy efficiency measures — like insulation — really start to make a difference.
How Insulation Helps You Save More Money
Lower energy prices are great, but reducing energy use is even better for your wallet — and your home’s comfort. Here’s how insulation helps:
1. Keeps Heat Inside Your Home
Homes that are poorly insulated lose heat quickly through walls, roofs, and floors. Insulation slows that heat loss, meaning your heating system doesn’t have to work as hard (or as long) to keep rooms warm. This can directly reduce the amount of gas (or electricity) you consume — lowering your bill, regardless of the price per unit.
2. Reduces Seasonal Spikes
With proper loft, cavity wall, and floor insulation, many homes stay warmer in winter without having to crank up the thermostat. This flattens the winter peak in energy use, so you don’t pay more just because it’s cold outside.
3. Offers Long‑Term Savings
Unlike a price cap — which is reviewed every 3 months — insulation helps for years. Pays for itself over time by continuously reducing energy use, no matter what happens to prices later in the year.
A 7 % price cap drop might save a household around £120–£150 over a year.
Insulation and draught‑proofing could cut energy use by 10–30 % — which paired with the price drop makes your household more efficient and cost effective.
What Insulation Do I Need And Where Is It Effective?
The main areas people can insulate to see a difference in conditons and energy savings are Roof, Wall and Flooring applications.Loft Insulation
Loft insulation works by creating a barrier that reduces heat loss from a building through the roof. Most commonly, this is done by laying insulating materials across the rafters and floor of the loft. We offer a wide range of loft insulation in easy to apply kits suitable for all spaces. These materials significantly slow the transfer of warmth from the living space below to the colder loft area above.
Wall Insulation
Wall insulation reduces the transfer of heat between the inside and outside of a building, keeping interiors warmer in winter and cooler in summer. When installed within wall cavities or on exterior walls, insulation creates a barrier that limits heat loss in cold weather and heat gain in hot weather. We offer all kinds of insulating materials for all situations and spaces.Floor Insulation
Floor insulation creates a barrier that reduces the transfer of heat between the inside of a building and the ground or unheated spaces below. In addition to conserving energy and lowering heating or cooling costs, floor insulation also helps reduce noise from footsteps and vibrations, making a building more comfortable overall. We’ve got products suitable for all types of floor insulation applications such as concrete, above the floorboards, and below the floorboards at the joist level.
