How do I apply for a 2025 insulation grant if my property is a listed building with heritage restrictions?
If you own or live in a listed building, you already know that improving your home’s energy efficiency isn’t as straightforward as it is for most UK properties. Heritage restrictions, planning controls, and unique construction methods can make even basic upgrades—like insulation—a complex challenge. Yet, with energy bills still rising and the UK government’s ambitious net zero targets, there’s never been a more important time to explore your options for insulation grants in 2025.
Government-backed schemes such as ECO4 and the Great British Insulation Scheme (GBIS) are providing unprecedented support for energy efficiency upgrades, but listed properties face unique hurdles. This guide is designed specifically for homeowners and tenants of listed buildings, offering a clear, step-by-step approach to navigating the grant application process—even when heritage restrictions apply.
Recent updates in 2025, including the introduction of the Warm Home Plan and expanded eligibility for properties with EPC ratings as high as D, mean more historic homes than ever could qualify for support [2][4]. However, the process requires careful planning, specialist advice, and a clear understanding of both grant rules and conservation requirements.

Understanding the Core of Insulation Grants for Listed Buildings with Heritage Restrictions
Insulation grants in the UK are primarily delivered through the ECO4 and Great British Insulation Scheme (GBIS). Both aim to reduce energy bills, cut carbon emissions, and improve home comfort. However, listed buildings—those protected for their historical or architectural significance—face additional hurdles due to legal restrictions on alterations [2][4].
Historical Context and Recent Developments
Historically, listed buildings were often excluded from mainstream energy efficiency schemes due to concerns about damaging heritage features. However, the government’s push towards net zero and the rising cost of living have prompted a shift. As of 2025, more schemes explicitly consider the needs of heritage properties, and local authorities are increasingly willing to work with homeowners to find sympathetic solutions [2][4].
The new Warm Home Plan (launching spring 2025) is expected to further streamline access, offering up to £15,000 per property for energy upgrades—including insulation—while requiring careful coordination with conservation officers [3][4].
Why This Matters for Homeowners
Listed buildings are often among the least energy-efficient in the UK, with solid walls, single glazing, and minimal insulation. This leads to higher heating costs and discomfort. Grants can help overcome the financial barrier to upgrading, but only if you navigate the heritage consent process correctly [2][3].
Real-World Example
Consider a Grade II listed cottage in Yorkshire: the owner wanted to install internal wall insulation but faced planning objections. By working with a TrustMark-accredited installer and the local conservation officer, they secured both grant funding and listed building consent for a breathable insulation system that preserved original features.
Comparison with Standard Properties
For standard homes, insulation grants are relatively straightforward—submit proof of benefits or income, arrange a survey, and proceed. For listed buildings, you must also:
- Secure listed building consent for any works affecting the character of the property
- Use specialist materials and installers familiar with heritage requirements
- Provide additional documentation to grant administrators
Common Misconceptions and Clarifications
- Misconception: "Listed buildings are always excluded from insulation grants."
Clarification: Many schemes now allow listed properties, provided works are approved by conservation officers and use appropriate methods [2][4]. - Misconception: "You can’t insulate a listed building at all."
Clarification: Internal wall, loft, and floor insulation are often possible with the right approach and materials.
A Comprehensive Step-by-Step Guide to Check Your Eligibility
Eligibility for insulation grants in 2025 depends on several factors: benefits, income, property type, energy efficiency, and additional criteria specific to listed buildings. Here’s how to check your status:
1. Benefit Requirements
Most schemes prioritise households receiving qualifying benefits, including:
- Universal Credit
- Housing Benefit
- Child Benefit (with income thresholds)
- Pension Credit
- Employment Support Allowance (ESA)
- Income Support
- Working Tax Credit
If you receive any of these, you are likely eligible for fully funded insulation measures—even for listed buildings, provided heritage consent is obtained [3][5].
Example: A retired couple in a Grade II* listed townhouse receives Pension Credit. They qualify for free loft insulation under ECO4, subject to listed building consent.
Tip: Gather recent benefit award letters and National Insurance numbers for all household members.
2. Income Thresholds
If you don’t receive qualifying benefits, you may still be eligible under income-based rules. For 2025:
- Household income typically must be below £31,000 per year (before tax), though some local authority schemes may set higher thresholds [2][3].
- Child Benefit recipients may qualify with higher incomes, depending on household size.
Example: A family of four in a listed farmhouse, earning £29,000 and receiving Child Benefit, may be eligible for GBIS support.
Tip: Prepare recent payslips, P60s, or tax returns as proof of income.
3. Property Criteria
Eligibility depends on:
- Property type: Owner-occupied, private rented, and social housing are all eligible, but private tenants need landlord consent [2][3][5].
- Listed status: You must declare if your property is listed and provide the listing grade (I, II*, II, etc.).
- Heritage restrictions: You must secure listed building consent for any works affecting the character or appearance of the property.
Example: A tenant in a Grade II listed flat must obtain both landlord and conservation officer approval before works can proceed.
Tip: Contact your local planning authority early to discuss heritage requirements. Keep copies of all correspondence.
4. Energy Efficiency Requirements
Most schemes require your property to have an EPC (Energy Performance Certificate) rating of D or below. For listed buildings, EPCs may not always be available or required, but you should:
- Obtain an EPC if possible, or provide evidence of poor energy performance (e.g., high bills, cold rooms).
- Some local authorities accept alternative assessments for heritage properties [2][4].
Example: A listed cottage without an EPC can submit a professional survey showing inadequate insulation and high energy use.
Tip: Request an EPC assessment from a provider experienced with historic buildings.
5. Additional Requirements
- Consent: Written confirmation from the local conservation officer or planning authority is essential.
- Specialist Installers: Use only TrustMark-accredited installers with heritage experience.
- Documentation: Prepare photos, plans, and details of proposed works for the grant application and consent process.
Example: A homeowner submits a detailed plan showing how internal wall insulation will avoid original plasterwork and cornices.
Edge Cases and Exceptions
- If your property is in a conservation area but not listed, you may still need planning permission for external works.
- Some local authorities offer additional support for heritage buildings, including specialist advice and funding top-ups [4].
- If you’re refused consent for one type of insulation (e.g., external wall), consider alternatives like loft or floor insulation.
The Complete Application Journey: From Start to Finish
Applying for an insulation grant for a listed building in 2025 involves several distinct phases. Here’s what to expect—and how to maximise your chances of success:
Phase 1: Preparation and Initial Application (1-2 weeks)
- Document Gathering: Collect benefit/income evidence, EPC or alternative assessments, proof of ownership or tenancy, and details of your property’s listed status.
- Heritage Consent: Contact your local planning authority to discuss your plans and begin the listed building consent process. This may require submitting detailed drawings and method statements.
- Online Application: Visit a reputable grant portal such as applyfreeboiler.co.uk/apply to start your application. Complete all sections honestly and upload supporting documents.
- What to Expect: You’ll receive an initial eligibility decision within 1-2 weeks. If further information is needed, respond promptly to avoid delays.
Phase 2: Assessment and Survey (2-4 weeks)
- Survey Scheduling: If eligible, a TrustMark-accredited installer will contact you to arrange a home survey. For listed buildings, a heritage specialist may also attend.
- Survey Process: Assessors will inspect your property, discuss insulation options, and review heritage constraints. They’ll prepare a detailed report for both the grant provider and conservation officer.
- Post-Survey: You’ll receive a final proposal outlining the works, materials, and any conditions set by the conservation officer. You may need to submit this to your local authority for final consent.
Phase 3: Installation and Completion (4-8 weeks)
- Installer Selection: Only proceed with TrustMark-accredited installers experienced in heritage properties.
- Scheduling: Agree a convenient installation date. Ensure all consents are in place before work begins.
- Installation Day: The team will follow strict protocols to protect historic features. Expect some disruption, but reputable installers will minimise impact.
- Post-Installation: A final inspection ensures work meets grant and heritage standards. You’ll receive documentation, warranties, and aftercare advice.
Potential Delays and How to Avoid Them
- Delays often occur if listed building consent is incomplete or documentation is missing. Start this process early and keep in regular contact with your local authority.
- If you encounter issues, escalate promptly to your grant provider or local council’s conservation team.

Some councils offer "top-up" grants or specialist advice for listed buildings. Always check with your local authority for the latest guidance and support.
Real-World Case Studies and Success Stories
Case Study 1: Grade II Listed Townhouse, London
A homeowner in a Georgian terrace wanted to install loft insulation. Working with a TrustMark installer and the local conservation officer, they secured both grant funding and listed building consent by using breathable insulation materials and ensuring no visible changes to the roofline. The result: a warmer home and a 25% reduction in heating bills [2][3].
Case Study 2: Rural Listed Cottage, Cumbria
A pensioner on Pension Credit applied for internal wall insulation under ECO4. The local authority required detailed plans and a heritage statement, but after a site visit and adjustments to the installation method, consent was granted. The homeowner now enjoys improved comfort and lower bills, with all costs covered by the grant [3][5].
Case Study 3: Private Tenant, Listed Flat, Bristol
A tenant in a listed flat worked with their landlord and the council to secure funding for floor insulation. The process took longer due to multiple consent layers, but by maintaining clear communication and using a heritage specialist, the installation was completed successfully under GBIS.
Lessons Learned:
- Start the heritage consent process early
- Work with experienced, accredited installers
- Document every step for both grant and planning authorities
