When it comes to eco-friendly heating solutions UK, families like yours often face a tough choice between being green and keeping bills low. If you’re juggling tight finances or living on a fixed income, upgrading to a greener heating system might seem out of reach.
In this guide, you’ll learn how the ECO4 grant scheme works, which heating upgrades you can claim, and how to apply step by step. If you’re planning broader energy-saving home upgrades, these measures will slot right in.
Get to know the ECO4 scheme
The ECO4 scheme is a UK government initiative designed to cut carbon emissions and slash energy bills in your home. It covers a range of upgrades, all without any upfront cost, so even if budgets are tight, you can still get a free boiler replacement or a new heat pump.
Here’s what ECO4 can cover:
- Free boiler replacement
- Underfloor insulation
- Cavity wall and loft insulation
- Heat pump installations
- Double glazing and window upgrades
According to Ecowise Installations, homes with lower energy ratings often get priority for these measures.
Check if you qualify
Not sure if you’re eligible for this eco-friendly boost? Let’s break down the main criteria so you can see if your home makes the cut.
- Household income or benefits status below your energy supplier’s threshold
- EPC rating of D or lower (EPC stands for Energy Performance Certificate)
- Residential property type such as a house, bungalow, or flat
- Approval from an authorised ECO4 provider
Wondering what counts as proof of income? It’s usually benefit letters or recent payslips.
Explore upgrade options
Once you know you qualify, you can choose the measures that suit your home layout and budget. Most ECO4 grants will cover these key options:
- Boiler replacement: swap an old, inefficient model for a modern A-rated unit
- Heat pumps: use air-source or ground-source systems to squeeze more warmth from electricity
- Insulation: add underfloor, cavity wall, or loft insulation to lock in heat
- Double glazing: install energy-efficient windows to reduce heat loss
- Solar thermal: harness the sun to heat water, one of the renewable energy heating options
Compare boiler vs heat pump
Deciding between a new boiler and a heat pump comes down to your existing setup and how you use heat. Not sure which suits your home? Let’s look at the key differences.
| Feature | Boiler replacement | Heat pump installation |
|---|---|---|
| Upfront cost covered | Fully funded | Often fully funded, but check with your provider |
| Energy efficiency | From around 60% to 95% | Typically 300% to 400% (coefficient of performance, or COP) |
| Space requirements | Fits in existing boiler space | Requires outdoor unit plus indoor components |
| Running costs | Lower than old models, but still reliant on gas | Generally lower, especially with off-peak electricity rates |
| System compatibility | Works with standard radiators | Best matched with underfloor heating or oversized radiators |
