About ECO4

What is the ECO4 scheme?

ECO4 — the fourth iteration of the Energy Company Obligation — is the UK government's flagship fuel-poverty programme. It places a legal duty on the major energy suppliers to fund energy-efficiency upgrades for low-income households living in the least efficient homes. The scheme is regulated by Ofgem and was originally scheduled to end 31 March 2026 but has been extended by 9 months — it now runs to 31 December 2026, when it will be replaced by the new Warm Homes Plan (launching January 2027).

Funding covers the whole-house retrofit — loft, cavity, internal or external wall insulation; first-time central heating; replacement boilers; or air-source heat pumps — at no cost to the household. Work is delivered by TrustMark-registered installers and the energy suppliers pay them directly.

Who typically qualifies

  • Someone in the household receives a means-tested benefit: Universal Credit, Pension Credit (Guarantee or Savings), Income Support, Income-based Jobseekers Allowance, Income-related ESA, Working Tax Credit, Child Tax Credit, or Housing Benefit.
  • Property has an EPC rating of D, E, F or G. Most pre-1990s homes without insulation upgrades fall into this band.
  • Owner-occupied or private rented (with landlord consent) — social housing tenants apply via their landlord.
  • LA Flex: some councils can extend eligibility to households not on benefits but in fuel poverty (e.g. with a disability or chronic health condition) — we check this in the eligibility form.

How to claim

1

60-second eligibility check

Tell us about your property, EPC, benefits status and the work you need. We screen for ECO4, GBIS and LA Flex in parallel.

2

Approved installer survey

If you screen in, a TrustMark-registered ECO4 installer will arrange a free home survey to confirm eligibility and assess the right measures.

3

Documentation & sign-off

Proof of benefits (recent award letter or DWP screenshot), property ownership and a current EPC. The installer compiles the file and submits it to the funder.

4

Installation

Once approved, work is scheduled and completed at no cost. Typical end-to-end timeline is 6–12 weeks depending on measure complexity.

About the BUS grant

What is the Boiler Upgrade Scheme?

The Boiler Upgrade Scheme (BUS) is a UK government grant administered by Ofgem that gives homeowners and small private landlords in England and Wales £7,500 towards the cost of replacing a fossil-fuel heating system with a low-carbon alternative. It applies to air-source heat pumps and ground-source heat pumps in domestic properties; biomass boilers are eligible in limited rural cases.

Unlike ECO4 there is no income test — eligibility is purely about the property and the installer. The grant runs to 31 March 2028 and is applied as a discount to your installer's quote, so you never pay it out-of-pocket and reclaim later.

Who typically qualifies

  • Property is in England or Wales (Scotland has its own Home Energy Scotland grant; Northern Ireland is not covered).
  • You are the property owner (or a private landlord). New-build custom homes are excluded; social housing not eligible.
  • You hold a valid EPC with no outstanding loft or cavity wall insulation recommendations. If yours has them, you'll need to address those first (typically via ECO4 or, from spring 2026, the new Warm Homes: Local Grant).
  • Installer is MCS-certified for the heat pump technology. We only match you with MCS firms that are active under BUS.

How to claim

1

60-second eligibility check

Tell us your property type, current heating, EPC status and postcode. We screen for BUS eligibility instantly.

2

MCS installer survey

Up to 3 MCS-certified installers in your area arrange a free home survey to size the system and quote in writing — with the £7,500 grant itemised.

3

Grant application

The installer applies to Ofgem on your behalf. Approval typically takes 5–10 working days. You don't fill in any forms.

4

Install & commission

Once approved, the installer schedules the install — usually 1–3 days on site. Old boiler removed, new heat pump commissioned, MCS certificate issued.

What replaces GBIS

Warm Homes: Local Grant — the new council-delivered scheme.

GBIS was a £1bn UK government scheme funded by the major energy suppliers and regulated by Ofgem. It paid for free or heavily subsidised insulation for households in lower council-tax bands with a low EPC rating. The GOV.UK referral service closed in October 2025; the scheme finished entirely on 31 March 2026, having delivered around 130,800 measures to roughly 95,500 households.

It's been replaced by Warm Homes: Local Grant — part of the wider Warm Homes Plan. Unlike GBIS (supplier-funded, delivered by private installers under Ofgem rules), the new scheme is government-funded and delivered through your local council. Coverage and eligibility vary by local authority, but the underlying offer is the same: free or subsidised insulation and clean heating for lower-income households in less efficient homes.

What's typically covered

  • Cavity wall, loft and room-in-roof insulation — the same primary measures GBIS used to fund.
  • Solid-wall insulation (internal & external) in many council areas.
  • Clean heating — heat pumps and modern controls. A wider set of measures than GBIS covered.
  • Eligibility is set by your local council — typically lower-income households in EPC D–G homes. Some areas extend it further via fuel-poverty discretion.

How to access it

1

60-second eligibility check

Tell us your council-tax band, EPC, benefits status and what insulation you need. We screen for Warm Homes: Local Grant, ECO4 (still running to Dec 2026) and any council-specific schemes in parallel.

2

We point you to your council's scheme

If your local authority has launched its Warm Homes: Local Grant programme, we surface the live link, eligibility criteria and how to apply. If they haven't yet (some councils are launching through 2026), we'll flag that too.

3

Or a free survey via ECO4

If you qualify for ECO4 (means-tested benefits + EPC D-G), a TrustMark-registered installer arranges a free home survey and applies on your behalf. ECO4 is still running to 31 December 2026.

4

Or a paid quote with a trade-in

If neither pathway fits, we still match you with FENSA / TrustMark-accredited insulation installers in your area — many run their own promotions.

The trade-in: a £1,000–£3,000 fallback.

For the majority of homeowners who don't screen in for ECO4 secondary measures, local council retrofit grants or LA Flex, the next-best option is an installer trade-in — a commercial promotion run by individual FENSA, Certass or CPA-accredited installers to win your work. It's not a UK government grant; it's a discount applied directly to the RRP of your new windows.

In Spring 2026 most participating installers in our network are offering between £1,000 and £3,000 off a whole-house replacement, depending on the number of windows and the condition of what's coming out. Single-glazed, condensation-prone, draughty or pre-2010 sealed units typically attract the highest trade-in value.

What you'll typically get back

  • £500–£1,000 for 4–7 old windows in a typical semi.
  • £1,200–£2,200 for 8–12 windows in a 3-bed detached.
  • £2,500–£3,000+ for 13 or more windows in larger homes.
  • Optional 0% APR finance via the installer (subject to credit check & affordability).

How it works

1

Tell us about your windows

One 60-second form. We capture the basics — postcode, number of windows, current condition.

2

We match you to installers running the trade-in

Up to 3 FENSA-approved installers who are currently active in your area and offering the promotion.

3

They survey, quote & apply the discount

A free home survey to measure up. The trade-in is itemised on the written quote — you see exactly what's been deducted.

4

You pick a quote (or none at all)

No obligation. Compare prices, warranties and timelines side-by-side. Most installs complete in 1–3 days.

About the Smart Export Guarantee

Smart Export Guarantee (SEG).

The Smart Export Guarantee requires every licensed energy supplier with over 150,000 customers to offer a tariff that pays solar owners for every kWh of clean electricity they export back to the grid. It replaced the older Feed-in Tariff in 2020 and continues to run with no current end date.

Rates are set by each supplier and vary widely — in 2026 the going rate is typically 5p–15p per kWh exported, with the highest tariffs from challenger suppliers like Octopus, EDF and E.ON Next. Rates are usually fixed for 12 months at a time. The grant is paid quarterly into your bank account on top of any bill savings from self-consumption.

Who typically qualifies

  • UK homeowner with a new MCS-certified solar PV system up to 5MW capacity.
  • A smart meter capable of half-hourly export readings (most SMETS2 meters qualify; some older SMETS1s need replacement).
  • You hold an active SEG tariff with a licensed supplier — you can switch suppliers or tariffs at any time.
  • Battery storage is optional but boosts earnings by letting you time-shift exports to peak rate periods.

How to claim

1

Get solar installed by an MCS firm

We match you with MCS-certified installers in your area. They issue an MCS certificate when the system is commissioned — you'll need this to register for SEG.

2

Check your smart meter is SEG-ready

Your installer will tell you. If your meter needs upgrading, your energy supplier will fit a free replacement, usually within 4–6 weeks.

3

Pick an SEG tariff & apply

Compare tariffs (Octopus Outgoing, EDF Export Plus, etc.) and apply directly with the supplier. You don't have to stay with your current supplier — many homeowners switch to maximise the export rate.

4

Get paid quarterly

Once registered, the supplier reads your half-hourly export data automatically and pays you each quarter. Typical 4kW system earns £150–£400/year from exports alone, on top of self-consumption savings.

Warm Homes Plan 2027.

The Warm Homes Plan is the UK government's ~£15 billion successor to ECO4 — the largest energy-efficiency programme in British history. Unlike ECO4, which was supplier-funded under Ofgem obligations, the Warm Homes Plan is government-funded direct from HMT, with an additional £1.5 billion in fresh grant money on top of the existing budget being rolled in.

Final eligibility criteria will be confirmed in the 2026 Autumn Statement (October 2026) but the headline policy direction is clear: broader EPC band coverage, more household types eligible, larger per-property budgets, and a stronger pivot toward heat pumps and low-carbon heating. Delivery shifts away from private installers under supplier obligations toward council-led programmes tied to local retrofit plans.

What we know so far

  • Total programme value of ~£15 billion across the parliamentary term, with the Warm Homes: Local Grant element already running.
  • Targets 5 million UK homes for energy-efficiency upgrades over the scheme's lifetime.
  • Delivered via your local council rather than private installers — so process and timelines will differ from ECO4.
  • Stronger focus on heat pumps, insulation and low-carbon heating than ECO4's mixed measures.

How to get ready

1

Get an up-to-date EPC

Almost every grant scheme requires a current EPC. If yours is over 5 years old or you've made improvements since, book a fresh one ahead of January 2027.

2

Register for early matching

Drop your details in our 60-second form and we'll flag when your council launches its Warm Homes Plan delivery — most are expected to announce by Q1 2027.

3

Address quick wins first

If you're on a means-tested benefit, you can still get free loft / cavity / heating under ECO4 right up to 31 December 2026. Don't wait if you qualify now.

4

Watch DESNZ announcements

Final eligibility criteria land at the Autumn Statement 2026. We'll update this page as the policy detail is published.

The main schemes in May 2026 are ECO4 (up to 100% funded insulation and heating for low-income households, extended to 31 Dec 2026), the Boiler Upgrade Scheme (£7,500 off an air-source heat pump in England & Wales, runs to 2028), and Warm Homes: Local Grant — the council-delivered replacement for GBIS, which closed 31 March 2026. The wider Warm Homes Plan (~£15bn) replaces ECO4 from January 2027.
ECO4 is targeted at low-income households and homes with an EPC rating of D, E, F or G. You typically qualify if someone in the household receives a means-tested benefit such as Universal Credit, Pension Credit, Child Tax Credit, or Housing Benefit. Most homeowners do not qualify — but our installers will check at no cost.
Several FENSA-approved installers run trade-in promotions in Spring 2026 that take £1,000–£3,000 off the RRP when you replace older or inefficient windows. The promotion is set by the installer and applied as a discount on your quote — Instant Home Quotes does not run the promotion itself. Promotion availability varies by region.
Yes. The BUS grant runs to 31 March 2028 and gives homeowners and small private landlords in England and Wales £7,500 towards an air-source heat pump (£7,500 also for ground-source). MCS-certified installers apply on your behalf and take it straight off your quote.
No problem — we'll still match you with up to 3 vetted installers running standard quotes plus any current trade-in promotions in your area. There's no obligation to accept any quote and you'll never pay a penny to Instant Home Quotes.
No. Instant Home Quotes is an independent matching service. We are not affiliated with DESNZ, Ofgem, or any UK government department. We match homeowners with FENSA, Certass and CPA-accredited installers who are authorised to deliver the grants and promotions listed above.
