Grants for Landlords: ECO4, GBIS, BUS & More
Upgrading rental properties to meet EPC C compliance can be expensive. Fortunately, several government-backed grant schemes can offset 25–100% of retrofit costs. This guide breaks down your options by region, eligibility, and process.
ECO4 (Energy Company Obligation)
ECO4
What it covers: Insulation (loft, cavity wall, external), heating upgrades (heat pump, boiler), heating controls
Who qualifies: Properties with a tenant meeting certain criteria (low income OR receiving certain benefits). Eligibility varies by energy supplier participation.
How it works: Energy suppliers (Ofgem-regulated) fund the work. You don't typically pay upfront — the supplier's contractor performs work, costs covered by the scheme. Net cost to you: often £0 or a co-contribution.
Apply at: Contact your energy supplier or visit Ofgem.gov.uk
Best for landlords with: Multiple properties with qualifying tenants. The largest single grant available in 2026.
Great British Insulation Scheme (GBIS)
GBIS
What it covers: Loft insulation and cavity wall insulation primarily
Who qualifies: Owner-occupiers and landlords with rental properties. Council tax band A–D, or on certain benefits.
Timeline: Schemes vary by region. Most are being wound down post-2025, with transition to local authority schemes. Check your council website for current eligibility.
Apply at: Your local council
Important: GBIS budgets are limited and many regions have closed applications. Confirm availability with your council before planning around this grant.
Boiler Upgrade Scheme (BUS)
BUS
What it covers: Heat pump installation (air source, ground source)
Who qualifies: Owner-occupiers only — BUS does not apply to rental properties. This scheme is not available to you as a landlord.
Note: If you want a heat pump in a rental property, you'll need to fund it privately or via ECO4 (if a qualifying tenant) or other regional schemes.
Home Energy Scotland (Scotland)
Home Energy Scotland Grant
What it covers: Insulation, heating upgrades, renewables
Who qualifies: Owner-occupiers and landlords with rental properties. Income thresholds apply (up to ~£35,000/year household).
How to apply: HomeEnergyScotland.org
Best for Scottish landlords: More generous than English schemes. Most common grant option in Scotland.
Nest Wales (Wales)
Nest Wales
What it covers: Insulation, heating, hot water systems
Who qualifies: Owner-occupiers and landlords. Income limits and council tax band requirements apply.
How to apply: Nest.gov.wales
Local Authority Flexible Eligibility (LAFE)
LAFE
What it covers: Insulation, heating, controls
Who qualifies: Properties where residents are "fuel poor" or at risk of fuel poverty. Criteria set by individual councils.
How to apply: Contact your local council directly. Availability and eligibility vary widely by region.
Combining Grants
A property may be eligible for multiple grants. Example scenario:
- ECO4: Covers insulation and boiler work (75–100% of cost) = £12,000 grant
- GBIS: Additional £1,500 for loft insulation if eligible
- LAFE: Potential top-up for remaining costs
Net cost to landlord: Potentially £0–£2,000 for a substantial upgrade
Pro tip: Always ask installers which grants they're qualified to deliver. Some contractors specialize in ECO4; others in GBIS. Using an installer aligned with the relevant scheme speeds up the process.
How to Apply: General Process
- Check eligibility: Visit the scheme's website or your council. Verify your property and tenant circumstances
- Get quotes: Request quotes from installers qualified for that specific scheme
- Submit application: Apply online or via paper (details by scheme)
- Wait for approval: Typically 2–6 weeks
- Arrange installation: Work with approved contractor(s)
- Pay any co-contribution: Some schemes require you to pay a portion
- Receive work & sign off: Installer completes work, you verify and sign completion certificate
Red Flags & Things to Avoid
- ❌ Don't pay upfront to a private company claiming they'll recover grant funding later
- ❌ Don't hire installers not approved by the scheme — work won't be eligible
- ❌ Don't assume your property/tenant qualifies without checking current rules
- ❌ Don't commit to a timeline before confirming grant approval
Timeline: When to Apply
2026 is a good year to apply — grant budgets are relatively healthy and installers aren't yet overbooked. By 2029, when the 2030 deadline looms, demand will spike and availability will be tight.
Recommended timeline: Apply for grants by end of 2027. This gives you 3 years to complete work before the 2030 deadline without rush fees.
