How It Works: Survey → Installation → Grant Award

1. Expert Home Survey

One of our MCS-accredited retrofit coordinators visits your property in Bolton, Manchester or nationwide to assess solid walls and eligibility for ECO4 grant insulation.

2. Fast, Clean Installation

Our qualified installers fix 50–130 mm of high-performance insulation boards, add a reinforced base coat, and finish with your choice of render or brick slips.

3. Grant Application & Approval

We complete and submit your ECO4 grant external wall insulation application, liaise with your energy supplier, and manage all paperwork for a hassle-free process.

Internal Wall Insulation FAQs

Am I eligible for ECO4?
If your home has an energy performance rating of D or below and you meet low-income criteria, you’re likely eligible. We’ll confirm during your free survey.
How long does installation take?
Most installations finish within 2–4 days for a semi-detached home, with minimal disruption.
Will my energy bills really go down?
Yes—clients average 25–30% savings. Actual savings depend on home size and usage patterns.
Are there any costs involved?
If fully funded by ECO4 or Warm Homes Fund, your installation is zero-cost. Otherwise a small contribution may apply.
Do I need planning permission?
Typically not for standard render finishes in non-conservation areas. We’ll advise if your project needs approval.
How do I maintain my insulation?
Periodic visual checks and gentle cleaning of the render will keep it performing for decades.
