Thousands of UK homeowners check whether they qualify for an insulation upgrade every month

Is it worth upgrading your insulation in 2026?

For a growing number of homeowners, the answer is yes. With energy prices still well above where they sat a few years ago, good roof and loft insulation is one of the few upgrades that keeps paying you back — holding heat in through winter and out through summer, so your home costs less to run all year round.¹

Many people assume it is an expensive job. In practice, a typical loft insulation upgrade costs far less than most expect — and with discounts available in many areas, it is more affordable than it has been in years.²

What’s changed — and why now?

Two things. The materials have moved on — modern fibreglass roll insulation performs better than older options and fits cleanly in hours. And competition between certified local installers means more homeowners can now access discounted installation in their area.³

The result is a warmer home in winter, a cooler one in summer, and lower energy bills year-round — for less than most people expect.
