Solar PV Insulation
What is Solar PV Installation
At ECO4, we support UK homeowners and tenants in improving their energy efficiency through free Solar PV (photovoltaic) installation, backed by government schemes like ECO4, GBIS, and LA FLEX. Solar panels generate clean electricity from sunlight, helping reduce your reliance on the grid and cutting your energy bills.
Even if you don’t meet the standard benefit criteria, LA FLEX allows local councils to extend support to more households. Save money, produce your own renewable energy, and reduce carbon emissions — check your eligibility today.
Understanding the ECO4 Scheme
The ECO4 scheme helps UK households lower energy bills and become more energy independent. If eligible, you could receive full or partial funding for Solar PV installation—allowing you to generate your own electricity from sunlight. It’s an ideal solution for reducing long-term energy costs and improving your home’s EPC rating, all with minimal or no upfront costs.
The Role of GBIS and LA FLEX
The Great Britain Insulation Scheme (GBIS) supports households with low EPC ratings (D–G) and low council tax bands by funding energy-saving upgrades like Solar PV installation. This allows you to generate renewable electricity and cut energy costs.
Not eligible through the standard route? LA FLEX gives local councils the flexibility to approve funding based on income, health, or housing conditions—making Solar PV systems accessible to more households in need.


What is the LA FLEX Route for Solar PV?
The Local Authority FLEX (LA FLEX) route expands access to government-backed energy schemes like ECO4 and GBIS, including Solar PV installations. It allows councils to help households that may not receive traditional benefits but still face challenges like low income, fuel poverty, or poor living conditions.
If your local authority participates in LA FLEX, you may qualify for Solar PV funding even without receiving benefits. The program offers four eligibility routes:
Route 1 – Income-Based: If your total household income is under £31,000 annually, you may qualify regardless of region or home size.
Route 2 – Vulnerability Indicators: Households can qualify if they meet at least two signs of vulnerability, such as children on free school meals or living in a low-income area.
Route 3 – Health Referrals: A healthcare professional can refer your household if a resident has a health condition worsened by energy inefficiency.
Route 4 – Local Criteria: Councils and energy providers may apply their own tailored criteria to support more households with Solar PV solutions.
Benefits of Solar PV Insulation
Lower Electricity Bills
Solar PV systems generate electricity from sunlight, helping you reduce reliance on the grid and save significantly on your energy bills.
Clean and Renewable Energy
Solar power is a renewable source that produces clean electricity, lowering your household’s carbon emissions and environmental impact.
Energy Independence
By generating your own power, you become less affected by rising energy costs and supply fluctuations.
Increased Property Value
Homes with solar panels are often more attractive to buyers thanks to improved energy performance and long-term savings.
Low Maintenance
Solar PV systems require minimal upkeep, with most panels lasting 25+ years and providing reliable energy with little effort.
Government-Backed Support
You may be eligible for funding or incentives through schemes like ECO4 and LA FLEX, making installation more affordable.
Am I Eligible for Solar PV Installation Funding?
You may be eligible for free or subsidized Solar PV installation through the ECO4 scheme if your household receives certain government benefits. This government-backed initiative is designed to support low-income and vulnerable households by improving access to renewable energy and lowering electricity costs. If you or someone in your home receives any of the following benefits, you could qualify:
Universal Credit (UC)
Child Tax Credit (CTC)
Working Tax Credit (WTC)
Income Support
Housing Benefit
Pension Credit (Guarantee or Savings Credit)
Income-based Jobseeker’s Allowance (JSA)
Income-related Employment and Support Allowance (ESA)
Child Benefit (subject to income-based criteria)
GBIS Eligibility for Solar PV Installation
To benefit from Solar PV installation through the Great Britain Insulation Scheme (GBIS), your property must meet specific criteria. These include having an Energy Performance Certificate (EPC) rating between D and G and falling within a lower council tax band—A to D in England or A to E in Scotland and Wales.
If your home meets these standards, you may qualify for funding to install solar panels, helping you generate renewable electricity, reduce energy bills, and boost your home’s energy efficiency.
