Looking to grow your insulation business in 2025? The Great British Insulation Scheme—also known as GBIS—could be the biggest opportunity for insulation installers this year.
With thousands of eligible UK households and simplified funding for single insulation measures, GBIS is unlocking a flood of new work for PAS 2030-certified contractors.
In this guide, we'll explain what the scheme is, who qualifies, and—critically—how to generate high-quality GBIS insulation leads without relying on overused platforms like Checkatrade or Rated People.
🔍 What Is the Great British Insulation Scheme (GBIS)?
The Great British Insulation Scheme (GBIS) is a UK government-backed energy efficiency programme that launched in 2023 and continues into 2025.
Unlike ECO4, which focuses on full-property retrofits for low-income households, GBIS is designed for quick-win upgrades, such as:
- Loft insulation
- Cavity wall insulation
- Solid wall insulation (internal or external)
- Flat roof or room-in-roof insulation
Key Features of GBIS:
- Faster, single-measure jobs
- Wider eligibility (not just benefits claimants)
- Funded by energy suppliers
- Delivered by PAS 2030 / TrustMark installers
That makes GBIS ideal for insulation firms who want to scale quickly with low-complexity installs.
👥 Who's Eligible for GBIS Insulation in 2025?
GBIS has two main target groups—making it broader than ECO4.
1. Low-Income Group
Households on qualifying benefits, including:
- Universal Credit
- Pension Credit
- Income-based JSA or ESA
- Housing Benefit
- Child Tax Credit
These leads may also qualify under ECO4 but are included in GBIS for single-measure installs.
2. General Group
The real opportunity lies here.
Households who:
- Are in Council Tax bands A–D (England), A–E (Scotland/Wales)
- Have an EPC rating of D or below
- Do not claim benefits, but still want to cut energy bills
👉 These households are often missed by traditional ECO4 lead gen services—and they're perfect GBIS insulation leads.
📈 Why GBIS Is a Game-Changer for Installers
Here's why UK insulation firms are targeting GBIS insulation leads in 2025:
- 🏡 More volume – There are millions more eligible homes than ECO4
- ⏱️ Faster installs – Loft and cavity wall insulation can be done in 1–2 visits
- 💰 Simplified paperwork – Less admin than ECO4
- 📞 Higher responsiveness – These leads are less likely to be shared or over-pitched
But there's a catch: these homeowners don't always know they qualify. That means whoever contacts them first—wins the job.
🎯 How to Find High-Intent GBIS Insulation Leads
Forget shared marketplaces. To find real GBIS leads that convert, you need a smarter targeting system.
✅ 1. Use HomeBuyerLeads to Target GBIS-Eligible Homes
With HomeBuyerLeads, you get:
- Daily lists of recent homebuyers in your postcode area
- Filters for Council Tax bands and EPC ratings
- Contact details for verified owner-occupiers
- Exclusion of homes with existing insulation
➡️ That means you're only contacting households that likely qualify—and haven't been pitched yet.
✅ 2. Educate Your Leads in the First Message
Start with a clear value offer:
"You may qualify for free loft or wall insulation under the Great British Insulation Scheme. No benefits needed. Let's check your eligibility—takes 2 minutes."
✅ 3. Focus on Fast-Follow-Up
Many GBIS jobs are quick installs, so leads convert fast. But only if you:
- Respond within 24 hours
- Offer grant application support
- Show previous GBIS installs (social proof helps)
📍 What Makes a GBIS Lead High-Quality?
The best GBIS insulation leads typically:
- Are recent homeowners (0–12 months)
- Live in EPC-rated D/E homes
- Don't already have upgraded insulation
- Want to cut energy bills in 2025
- Respond to local, trusted outreach
HomeBuyerLeads helps you target these leads with exclusive, property-data-driven insight—not random internet forms.
🧠 Final Thoughts: Get Ahead of the GBIS Curve
Most UK insulation firms are still stuck chasing ECO4 leads through crowded, competitive platforms.
