Boiler Grants
Free Boiler Grants in Scotland
If your boiler is old, broken, or inefficient, you may qualify for a free replacement through government-backed energy schemes. Here is what you need to know.
Free boiler replacement in Scotland is primarily available through ECO4, which funds a new A-rated boiler at no cost for qualifying households. Eligibility requires receiving certain benefits such as Universal Credit or Pension Credit, or having a household income under £31,000 through the LA Flex route.
Free boiler replacements are primarily available through the ECO4 scheme. Eligibility depends on your income, benefits, property type, and current heating system.
How Free Boiler Grants Work
The UK Government requires large energy companies to fund energy efficiency improvements in qualifying homes. This includes replacing old, broken, or inefficient boilers with modern, energy-efficient models. The homeowner pays nothing if they meet the eligibility criteria.
The main route to a free boiler in Scotland is through the ECO4 (Energy Company Obligation) scheme. This programme runs until March 2026 and targets low-income and vulnerable households living in energy-inefficient properties.
In some cases, Warmer Homes Scotland (a Scottish Government programme) may also cover boiler replacement for households receiving certain benefits.
Who Qualifies for a Free Boiler?
To qualify for a free boiler replacement through ECO4, you typically need to meet criteria in two areas: personal eligibility and property eligibility.
Personal Eligibility
You may qualify if you:
- Receive Universal Credit, Pension Credit, Income Support, or Employment & Support Allowance
- Receive Jobseeker's Allowance (income-based), Working Tax Credit, or Child Tax Credit
- Receive Child Benefit and meet income thresholds
- Have a household income under £31,000 (through Local Authority Flex)
- Are considered vulnerable due to age, health conditions, or having young children
Property Eligibility
- Your property must have an EPC rating of D, E, F, or G
- You must own the property or be a private tenant (with landlord consent)
- Your current boiler must be broken, inefficient, or non-condensing
- The property must be your main residence in Scotland
What Type of Boiler Will You Receive?
If you qualify, the replacement will typically be a modern condensing boiler that meets current efficiency standards. The exact model depends on your property size, heating requirements, and existing pipework.
In some cases, particularly where the property does not have a gas supply, alternatives such as an air source heat pump or electric storage heaters may be recommended instead. The surveyor will assess what is most appropriate for your home.
All installations are carried out by Gas Safe registered engineers (for gas boilers) or MCS certified installers (for heat pumps), ensuring work meets safety and quality standards.

Common Questions
Is it really free?
Yes. If you meet the eligibility criteria, the full cost of the boiler and installation is covered by the energy company funding the ECO4 scheme. You pay nothing.
Can I choose my own boiler?
The installer will recommend an appropriate boiler based on your property. You cannot typically choose a specific brand or model, but all replacements will be modern, efficient units.
How long does the process take?
From initial application to installation, the process typically takes 4-12 weeks depending on demand and documentation requirements.
Be Cautious of Scams
Legitimate schemes will never ask you to pay an upfront fee or deposit. Be wary of unsolicited calls or door-to-door salespeople claiming to offer free boilers. Always verify the installer is registered with the relevant scheme before proceeding.
