Predicted DIY Insulation Trends in 2026

DIY loft insulation is evolving fast. 2026 is shaping up to be a defining year for how UK homeowners upgrade their homes.

With energy bills still high and likely to get higher with the energy price cap going up from January (the price per unit limit set to increase) meaning more financial pressure.
Fire safety awareness is leading to a greater consideration of what materials householders bring into their property. The insulation DIY market is shifting in clear measurable ways

“Consumers want clarity: “How much will this save me?”

Here are the Top 5 DIY Loft Insulation Trends for 2026, grounded in what we’re seeing across the UK:

1️⃣ Comfort‑first, itch‑free insulation
DIYers are demanding materials that are clean, enclosed, and easy to handle. Fully‑encapsulated, itch‑free glass wool rolls should be the go‑to choice for homeowners who want a quick, mess‑free install.

2️⃣ Fire‑safe materials as standard
Non‑combustible insulation is no longer a “nice to have.” With growing fire safety awareness home owners should be asking if the insulation they put in their loft is non-combustible A1 certified, and with any encapsulation being fire-retardant grade. This should become the default for loft insulation upgrades

3️⃣ Layer‑and‑upgrade retrofits
Instead of ripping out old insulation, households are topping up to 270–300mm using multi‑layer systems. It’s the fastest route to lower bills and better EPC ratings, and it’s driving demand for 100mm–200mm roll formats.

4️⃣ Bulk‑buy value & pallet delivery
Economic pressure is pushing householders towards full loft DIY insulation upgrades in one go, with delivered-to-the-door full quantity being the economic preference

5️⃣ Clear energy‑saver branding & ROI messaging
Consumers want clarity: “How much will this save me?” Products that communicate energy savings, payback speed, and performance benefits are winning attention.

2026 is the year DIY insulation becomes cleaner, safer, easier, and more financially strategic.
