An ECO4 retrofit assessment is the first step towards accessing free or subsidised energy efficiency upgrades for your Merseyside home. This government-funded scheme offers insulation, heating, and renewable energy solutions to reduce energy bills and improve comfort.
At Warmr, we make the process seamless, but preparing your home for the assessment can ensure the best results. Here’s how to get ready for an ECO4 retrofit assessment and what to expect.
What Is an ECO4 Retrofit Assessment?
An ECO4 retrofit assessment is a free survey conducted by experts to evaluate your home’s energy efficiency and recommend upgrades like insulation or heat pumps.
The assessment identifies areas of heat loss, assesses your heating system, and determines your eligibility for fully funded upgrades. In Merseyside, where many homes have low EPC ratings, this step is crucial for accessing ECO4 benefits.
Steps to Prepare Your Home
1. Clear Access to Key Areas
Ensure assessors can easily access your loft, walls, and heating system. Clear clutter from the loft hatch, remove items blocking external walls, and provide access to your boiler or heating controls.
2. Gather Relevant Information
Have details ready about your home, such as its age, construction type, and any known insulation or heating issues. Information about your energy bills or benefits status can also help confirm eligibility.Don’t worry if there’s information you can’t find, our assessors can help with this.
3. Check for Existing Issues
Note any signs of damp, mould, or draughts, as these can inform the assessor’s recommendations. Addressing these issues through ECO4 upgrades can improve your home’s health and comfort.
4. Prepare Questions
Jot down any questions about ECO4, such as which upgrades are available or how long installation takes. Our team is here to provide clear answers.
What to Expect During the Assessment
The assessment typically takes 1–2 hours and includes:
Inspecting insulation levels in the loft, walls, and floors.
Evaluating your heating system’s efficiency.
Checking for energy loss using tools like thermal imaging.
Discussing your household’s needs, including benefits or health conditions.
Warmr’s assessors will provide a detailed report recommending upgrades like loft insulation or air source heat pumps, tailored to your home’s needs.
Why Prepare for an ECO4 Assessment?
Proper preparation ensures an accurate assessment, maximising the benefits you receive. Upgrades can save up to £400 annually on energy bills, improve comfort, and reduce your carbon footprint. With limited ECO4 funding, acting now is essential.
