Yes! You can use ECO4 to fund insulation for your home, and then claim the £7,500 Boiler Upgrade Scheme grant for a heat pump. This is one of the most powerful combinations.
No, both schemes cover insulation and are funded by energy suppliers under the Energy Company Obligation, so you can only use one. Usually, ECO4 is better if you qualify for it.
Not at all. The Warm Home Discount is a £150 bill credit and operates completely separately from home improvement grants like ECO4 or BUS.
Yes, the EV chargepoint grant is managed by the OZEV and is entirely separate from energy efficiency grants, meaning you can claim both without issues.
If you qualify for maximum support (e.g., ECO4 for insulation and solar, BUS for a heat pump, plus EV and WHD), the combined value can easily exceed £15,000.
No, you can apply sequentially. In fact, getting ECO4 insulation first will improve your home's EPC rating, making it ready and compliant for a Boiler Upgrade Scheme heat pump later.
