How small changes can lead to big savings for landlords in 2025

In today’s market, energy efficiency isn’t just a nice-to-have — it’s a requirement. With tightening government regulations, rising utility bills, and tenants demanding greener homes, landlords can’t afford to ignore their property’s energy performance.

At Abbington Property Maintenance, we work with landlords across South West London to identify cost-effective energy upgrades that don’t just comply with EPC standards — they actually raise tenant satisfaction and cut long-term costs.

Here are some of the smartest energy-efficient upgrades landlords are making in 2025 — and how they’re paying off.

1. LED Lighting: The Fastest Win

Still using halogen bulbs? Upgrading to LED lighting is a low-cost switch that reduces lighting energy use by up to 75%.

Real example: One landlord in SW6 replaced all communal hallway lighting in a 3-flat conversion with LEDs. Result?

• Energy use down 63%

• Annual savings: £180

• EPC rating improved from E to D

2. Smart Thermostats: Control & Comfort

Devices like Google Nest or Tado give tenants more control over heating — while landlords see lower energy usage and fewer complaints.

Bonus: Many of these smart thermostats now integrate with HMO and multi-flat systems. You stay in control, while tenants enjoy a warm flat without waste.

3. Draught Proofing & Insulation Upgrades

Heat loss through windows, doors and uninsulated lofts is a major EPC killer.

Typical fixes we recommend:

• Sealing window gaps

• Adding thermal door strips

• Upgrading roof insulation (now eligible for local authority grants in some boroughs)

Client case study – Chelsea SW3: Loft insulation + front door draught proofing saved £310 in annual heating costs and improved the EPC from D to C. The work paid for itself in under 18 months.

4. Efficient Boilers & Heating Systems

If your boiler is over 10 years old, chances are it’s operating at under 80% efficiency.

We help landlords:

• Replace old combi boilers with A-rated condensing boilers

• Install smart TRVs (thermostatic radiator valves)

• Time heating intelligently with zoning systems

Fact: A new boiler install often improves the EPC rating by two full bands.

5. Window Upgrades: Not Always Full Replacements

Full double glazing isn’t always necessary. Secondary glazing and modern film coatings can make a huge difference.

For listed buildings or conservation zones (common in South West London), we help landlords find approved solutions that don’t fall foul of planning restrictions — but still improve thermal performance.

6. Energy-Efficient Appliances in Furnished Rentals

Providing your tenants with A++ rated fridges, washing machines, and tumble dryers doesn’t just save energy — it also builds goodwill and cuts emergency callouts.

Top Tip: Appliances often qualify for business tax deductions if supplied by landlords.
