How Loft Insulation & Boarding Can Help Reduce Energy Bills

Why Is Loft Insulation Important for Energy Efficiency?

Up to 25% of a home’s heat is lost through the roof if it’s not properly insulated. Loft insulation acts as a thermal barrier, reducing heat loss during winter and keeping your home cooler in the summer. This means your heating system doesn’t have to work as hard — leading to lower energy bills.

How Loft Boarding Complements Insulation

You might be wondering: Does adding loft boarding affect insulation? The answer is — not if it’s done properly. In fact, professionally installed raised loft boarding can enhance insulation performance by:

• Preventing compression of the insulation material (which reduces its effectiveness)

• Sealing gaps to minimise heat escape

• Making it easier to maintain and inspect your insulation over time

Energy-Saving Benefits of Insulated and Boarded Lofts

Here are just a few of the long-term advantages:

• ✅ Reduced energy bills — Save up to £250 per year on heating costs (Energy Saving Trust)

• ✅ Improved thermal comfort — Keep your home warmer in winter and cooler in summer

• ✅ Long-term savings — Insulation can last 40+ years and pays for itself many times over

• ✅ Increased property value — A more energy-efficient home is more attractive to buyers

• ✅ Extra usable space — Loft boarding creates safe storage without damaging insulation

Common Questions Answered

“Does loft boarding help reduce heating bills?”
Yes — when combined with proper insulation, it creates an energy-efficient thermal envelope that reduces heat loss.

“Can I board over existing loft insulation?”
Absolutely. Using raised loft boarding systems allows you to preserve insulation depth and airflow.

“How much energy can I save with loft insulation?”
A typical detached home can save up to £445 per year on energy bills by upgrading to 270mm of loft insulation (source: Energy Saving Trust).

DIY vs Professional Loft Insulation and Boarding

While DIY kits are available, poorly installed insulation can lead to condensation problems, poor airflow, and reduced performance. Hiring a professional ensures:

• Correct insulation depth (270mm is the recommended standard)

• Proper ventilation to avoid damp or mould

• Safe and secure boarding without damaging joists or wiring

Conclusion: Invest Now, Save for Years

Loft insulation and boarding aren’t just about comfort — they’re a smart investment that pays off year after year. Whether you’re looking to cut heating costs, add storage, or boost your EPC rating, upgrading your loft is a practical step towards a more energy-efficient home.
