Great British Insulation Scheme
Under the Great British Insulation Scheme, you could get free or heavily subsidised loft, cavity wall or solid wall insulation to help cut your energy bills. Envirofit makes it simple, we check your eligibility and manage the whole process for you.
Here’s a simple, step-by-step guide to help you understand what to expect during the installation process.
Initial Survey and Checks
Before anything is installed, a qualified surveyor will visit your home to carry out a full assessment. They’ll check your roof’s condition, orientation and pitch, as well as assess your current energy usage to make sure solar panels are suitable for your property.
If you’re applying through ECO 4, this visit is also used to confirm eligibility and gather any documents needed for funding approval. Once that’s all sorted, installation can usually be arranged within a few weeks.
Preparation on Installation Day
On the day of installation, the team will arrive with all the equipment needed. Don’t worry — most standard installations only take one or two days. You don’t need to move out, but the team may need access to your loft, fuse box and parts of the house to run wiring.
They’ll set up scaffolding to safely access your roof. This may go up a day or two beforehand and come down a few days after the work is completed.
Fitting the Solar Panels
The panels are carefully mounted on your roof using a frame, which is securely fixed into your roof structure. The panels are then connected with cabling that links them to an inverter — this clever bit of kit turns sunlight into usable electricity.
If you’re getting a battery installed too (which some homeowners do through ECO 4), that will usually be fitted near your fuse board or in a utility area.
Connecting to Your System
Once the panels and inverter are in place, your installer will connect everything to your home’s electrical system. They’ll run tests to make sure it’s all working safely and efficiently.
They’ll also help you understand how to monitor your energy use, either through a small digital display or a mobile app. It’s incredibly satisfying to see how much free energy your panels are generating each day.
Clean-Up and Certification
Once installation is complete, the team will tidy up, remove any equipment and take down scaffolding if it’s no longer needed.
You’ll be given all the relevant paperwork, including warranty information and an MCS certificate (which proves the system meets UK standards). If you’ve had the work done under ECO 4, this paperwork is also needed to confirm your grant funding.
Aftercare and Peace of Mind
A good installer will offer support if you have questions in the future or notice anything unusual. Most solar panel systems require very little maintenance, but it’s good to know you’ve got help on hand if needed.
If your installation was part of the ECO 4 Scheme, you can relax knowing it’s been completed by certified professionals as part of a government-backed initiative.
