Check All Scheme EligibilityFrequently Asked Questions
Can I apply for multiple schemes at the same time?
Yes, you can often combine different schemes. For example, you might qualify for ECO4 for a boiler replacement and GBIS for additional insulation. However, you cannot receive funding for the same measure from multiple schemes.
Which scheme offers the best value for money?
ECO4 typically offers the highest value with up to £10,000+ in funding for comprehensive home improvements. However, the best scheme depends on your eligibility, property type, and specific needs. If you only need insulation, GBIS might be more accessible.
How do I know which scheme I'm eligible for?
Eligibility varies by scheme. ECO4 requires benefits or low income plus poor EPC rating. GBIS focuses on Council Tax bands A-D. BUS has no income restrictions but requires specific heating system replacements. Use our eligibility checker to see which schemes you qualify for.
Do these schemes have waiting lists?
ECO4 can have waiting lists in high-demand areas as funding is limited. GBIS and BUS typically have shorter wait times. WHD is processed annually. We recommend applying early and to multiple schemes where eligible.
What's the difference between ECO4 and the old ECO3 scheme?
ECO4 has expanded eligibility criteria, higher funding limits, and focuses more on whole-house solutions. It also includes more support for vulnerable households and has extended the scheme until March 2026 with increased funding.
