Your Heating Upgrade Questions Answered, ECO4 FAQs
Confused about heating grants or wondering if you can get a free boiler in Northampton? You’re not alone! We’ve gathered your most common questions and answered them clearly, so you know exactly what to expect with the ECO4 scheme.
What is the ECO4 scheme?
The ECO4 scheme (Energy Company Obligation phase 4) is a government-backed initiative designed to help UK households improve their energy efficiency. For many, that means a free boiler upgrade, insulation improvements, or switching to an eco-friendly heating system, all at little or no cost.
Who qualifies for a free boiler in Northampton?
To be eligible for a free boiler through ECO4, your household must meet certain criteria, including:
Receiving qualifying benefits (like Universal Credit or Income Support)
Living in a property with a low Energy Performance Certificate (EPC rating of D or below) [Link]
Being a homeowner or a tenant (with landlord permission)

I live in the NN3 postcode, are heating grants available here?
Yes! If you’re in NN3 or anywhere across Northamptonshire, you can apply for heating grants under ECO4. We work with families across the region to access the funding they’re entitled to.
Is it really “free”?
In many cases, yes! If you qualify under ECO4, your new boiler, installation, and even insulation could be covered completely by the grant. There may be occasional small top-up costs in complex cases, but we’ll always be transparent upfront.
I rent – can I still apply?
Yes, tenants can apply for ECO4 grants, but you’ll need your landlord’s consent for any work to be carried out. We’re happy to speak to your landlord and explain the benefits too!
What kind of heating systems can I get?
Depending on your property and eligibility, you could receive:
A modern, energy-efficient boiler
An air source heat pump
Loft or cavity wall insulation
Smart controls or thermostats
We’ll recommend the best solution for your home and budget (and future energy bills!).
