If you live in North Wales—whether you own your home, rent it, or are a landlord—chances are you’ve heard of the ECO4 grant. It’s a government-scheme to help upgrade homes for better energy efficiency, reduced heating costs, and lower carbon emissions. But exactly how much financial help can you expect? In this post, we’ll break down:

What ECO4 is
Who’s eligible (especially here in North Wales)
What types of upgrades it covers
Typical grant values locally
What to do next

What is the ECO4 Grant Scheme?

ECO4 (Energy Company Obligation, phase 4) is the UK government’s scheme (applicable in England and Wales) that requires energy suppliers to fund energy efficiency improvements in homes—especially those in fuel poverty or with inefficient heating.

In Wales, this scheme is fully operative until March 2026 (and may get extended) It provides non-repayable grants—i.e. you don’t pay this money back.

Who Qualifies — Homeowners, Landlords & Renters in North Wales

Here are the main eligibility criteria, especially relevant to people in North Wales:

Your property’s Energy Performance Certificate (EPC) rating: commonly must be in band D, E, F or G (i.e. not very energy-efficient) to qualify.
You or someone in your household must be on certain means-tested benefits (for example, Universal Credit, Housing Benefit, Pension Credit, etc.).
For landlords: private landlords can apply provided the tenant meets eligibility criteria (i.e. benefit receipt, EPC rating) and agrees to the works.
For private renters: landlord permission may be needed for installations.
Income thresholds also often apply, especially if you are not on benefits but rely on “flexible eligibility” routes via your local authority. In North Wales there are specific thresholds.

So many homeowners, landlords, and renters who have older homes, little or no insulation, off-gas heating, or who are on low income could qualify.

What Does the Grant Cover?

If you're successful, ECO4 grants in North Wales (and Wales generally) can cover 100% of the cost of approved measures. This includes:

Insulation: loft, cavity wall, solid wall (internal or external), roof, etc.
Heating system upgrades: replacing old boilers, installing air source heat pumps, or first-time central heating in some cases.
Solar PV (panels), under certain conditions (often off-gas grid or as part of a package with heating/insulation improvements).
Smart heating controls, new thermostats etc., to help make heating more efficient.

You won’t need to repay the grant, and in many cases no upfront cost if you qualify.

Why the Grant Amount Varies

The actual value you get depends heavily on:

How inefficient your home currently is (EPC rating, type of walls, insulation status)
What measures your property needs (just insulation vs full heating system + insulation + solar PV etc.)
Size of the property (larger, detached homes cost more to upgrade)
Location / off-gas grid or not (rural properties often are more expensive to work on, but may qualify for more support)
Which eligibility route you fall into (benefits route vs local authority flexible route (“Flex” or “LA-Flex”))

What It Means for Homeowners, Landlords & Renters in North Wales

Homeowners: If your home is older, with poor insulation or off-gas, and you’re on benefits or low income, you may be able to get tens of thousands of pounds worth of upgrades free. Even modest upgrades can reduce your energy bills substantially.
Landlords: If your tenants meet eligibility criteria, upgrading properties now can reduce voids and maintenance costs, enhance property value, and meet upcoming regulations.
Renters: You will need landlord cooperation, but much of the cost is covered. Better insulation and heating means more comfort and lower bills for you too.

What You Should Do If You Live in North Wales

Check your EPC rating — first step. If it’s D, E, F, or G, you may be eligible.
Find out if you or someone in your household receives an eligible benefit, or whether you qualify via the income thresholds/local authority Flex route.

Act sooner rather than later — ECO4 funding ends March 2026. Delays may mean missing out.

Summary

For homeowners, landlords & renters in North Wales, the ECO4 grant can be very substantial:

As little as £8,000-£10,000 for more modest upgrades
Up to £20,000-£40,000+ for major works (insulation, heating system changes, solar, etc.)
Fully funded (no repayment) if you qualify

If your home is poorly insulated, has an old heating system, or you’re on low income / benefits, this is a very powerful opportunity both to improve comfort and save on energy bills.
