Energy Bill Help Schemes UK 2026 What Each Scheme Actually Covers
Energy bill support in 2026 is no longer a universal blanket payment. It is a patchwork of targeted schemes, each with separate eligibility rules, application processes, and funding caps. Homeowners must check their household income, property type (EPC rating), heating system, and council tax band before applying. Applying for the wrong scheme wastes time and may delay access to the correct one.

The main schemes available in 2026 are the Warm Home Discount, the Energy Company Obligation (ECO4), the Great British Insulation Scheme, and the Home Heating Support Fund (Scotland-specific). This article explains exactly which scheme fits which household profile, how much each pays or covers, and how to apply without falling for scams.
Warm Home Discount 2026 Who Gets the £150 and Who Must Apply
The Warm Home Discount provides a one-off £150 credit on electricity bills for winter 2026/27, administered by participating energy suppliers (Ofgem, Warm Home Discount scheme guidance, 2026). The Core Group receives the discount automatically. This group includes households receiving Pension Credit Guarantee Credit. No application is needed (GOV.UK, Warm Home Discount: eligibility).
The Broader Group requires an application. Each energy supplier sets its own criteria, typically based on low income and high energy costs. Homeowners must apply by late February 2027 through their supplier’s portal (Ofgem, WHD broader group rules). The rebate is applied to the electricity account, not paid as cash. If the household uses mains gas only, the supplier may credit the gas account instead. The £150 figure is confirmed by GOV.UK, Warm Home Discount 2026/27 rates.
Energy Company Obligation (ECO4) Free or Subsidised Insulation and Heating Upgrades
ECO4 runs from April 2022 to March 2026 (extended to 2026 delivery deadline). It provides free or heavily subsidised insulation (loft, cavity wall, solid wall, underfloor) and first-time central heating to low-income households (DESNZ, ECO4 scheme overview, 2026). Eligibility requires the household to be in receipt of a qualifying benefit. The list includes Universal Credit, Pension Credit, Income Support, and Child Tax Credit below a threshold. The property must have an EPC rating of D, E, F, or G (GOV.UK, ECO4 eligibility).
The scheme covers 100% of the cost for qualifying households. Non-qualifying households in the same property are not eligible. Only the main beneficiary household counts. Installations must be carried out by an MCS-certified or PAS 2035-accredited installer. The homeowner does not pay upfront. The energy supplier claims the funding. Source for EPC and benefit criteria: DESNZ, ECO4: guidance for households, 2026 update.
Great British Insulation Scheme Means-Tested Loft and Cavity Wall Insulation
The Great British Insulation Scheme (GBIS) is a separate, smaller fund. It offers free loft insulation and cavity wall insulation to households with an EPC rating of D or below and a combined household income under £31,000 (DESNZ, Great British Insulation Scheme: eligibility, 2026). Unlike ECO4, GBIS does not cover solid wall insulation, underfloor insulation, or heating system upgrades. It is strictly cavity walls and loft insulation.
The scheme is delivered through energy suppliers with a specific allocation of funding. Once a supplier’s allocation is exhausted, applications close for that supplier. Homeowners apply via their energy supplier’s GBIS portal. The supplier arranges the survey and installation through their approved installer network. Source for income threshold: DESNZ, GBIS household income guidance, 2026.
Home Heating Support Fund (Scotland) £200 to £300 for Off-Grid Homes
The Home Heating Support Fund (HHSF) is a Scottish Government scheme. It provides a one-off payment of £200 to households using mains gas and £300 to those using alternative fuels (oil, LPG, biomass, electric storage heaters) (Scottish Government, Home Heating Support Fund 2026, 2026). Eligibility requires households in Scotland to be in receipt of a qualifying benefit (same list as ECO4) or have a combined household income under £20,000.
Application is online via the Scottish Government’s dedicated portal. Payments are made directly into the household’s bank account, not through the energy supplier. The fund is capped annually. In 2026 the total allocation is £18 million, so applications are processed on a first-come, first-served basis until funds are exhausted. Source for payment amounts and cap: Scottish Government, HHSF 2026 scheme rules.

Eligibility Check Which Scheme Fits Your Household Profile
Households on Pension Credit automatically receive Warm Home Discount (Core Group). They may also qualify for ECO4 if the property is poorly insulated. Low-income households with children likely qualify for ECO4 (full insulation and heating) and the Warm Home Discount Broader Group. Check with your supplier for the Broader Group criteria.
Households with income under £31,000 and a poor EPC rating likely qualify for the Great British Insulation Scheme (loft and cavity wall only). Scottish households on benefits or low income should apply for the Home Heating Support Fund for a cash payment. This scheme is separate from UK-wide schemes. Households with solid walls or needing heating upgrades should note that only ECO4 covers these. GBIS does not. Source for eligibility cross-check: GOV.UK, Help with your energy bills, 2026.

How to Verify an Installer MCS, TrustMark, and PAS 2035 Certification
All ECO4 and GBIS installations must be carried out by an installer certified under PAS 2035 (the quality standard for energy efficiency retrofits) and registered with MCS (Microgeneration Certification Scheme) or TrustMark (DESNZ, ECO4 installer requirements, 2026). Homeowners should never pay an installer upfront for ECO4 or GBIS work. The energy supplier pays the installer directly after the installation is signed off.
To verify an installer, check the MCS register at mcs-certified.com or the TrustMark database at trustmark.org.uk. Both are free to search. For the Warm Home Discount, the homeowner does not need to find an installer. The rebate is applied by the supplier automatically or via a simple online application. For the Home Heating Support Fund, there is no installer involvement. The payment is cash to the household.
