ECO4-Funded Upgrades for Private Landlords

Private Landlords

If you're a private landlord with tenants or renters receiving eligible benefits, you may be able to access ECO4 funding to improve the energy efficiency of your property.

AirEx Floorvent is now an approved ECO4 measure, designed specifically for homes with suspended timber floors that can be hard to insulate cheaply. It’s a simple, fast and low-disruption way to meet your obligations under Minimum Energy Efficiency Standards (MEES) and reduce tenant heating costs.

Approved under ECO4 for suspended floor insulation
Adds 2–4 SAP points, improves EPC rating
Ideal for Band D to G homes
Quick, low-impact installation with high tenant acceptance

Floorvent replaces traditional air bricks with smart airflow control. It reduces draughts and underfloor damp while keeping ventilation effective. Installation takes under an hour, with no access to the main living space required, which is perfect for occupied rental properties.

ECO4 funding is available until 2026 and supports a whole-house approach to energy efficiency. Floorvent helps tackle one of the most overlooked areas of heat loss, improving tenant comfort and helping landlords comply with EPC and MEES requirements.

Suitable for homes with suspended timber floors only

12% average heat loss reduction
Minimal disruption for tenants
Compliant with PAS 2035/2030

Cut heat loss, boost EPC ratings

Not eligible for ECO4?

If your tenants don’t meet the ECO4 criteria, Floorvent can still be installed as a privately funded measure. Installation is fast and affordable, and the benefits are the same.

You will need to use an approved and trained installer, and while our installer network is growing, coverage is limited in many areas. If you have a significant number of suitable homes, do introduce us to your in-house team or contractors and we can get them set up to install the system.
