Cut costs, boost yields: 6 energy-efficient upgrades for landlords
As a landlord, maximising rental yield isn’t just about increasing rent — it’s also about reducing long-term operating costs. Energy-efficient upgrades offer a win-win: they lower utility bills for tenants, improve the property’s EPC rating, and make your property more attractive to today’s eco-conscious renters.
At Checkatrade, we’ve helped thousands of landlords find trusted trades to deliver high-impact improvements. Below are six energy-efficient upgrades that typically cost under £1,500 and can meaningfully increase your net yield.
1. Install thermostatic radiator valves (TRVs) - From £200
TRVs let tenants control the temperature in individual rooms, preventing wasted heat and cutting energy usage. They’re a simple but powerful way to improve comfort and reduce heating bills, especially in larger properties or HMOs.
Did you know? Properties with TRVs can reduce heating energy use by up to 17%, according to the Energy Saving Trust.
2. Upgrade to LED lighting throughout - From £150
Swapping out old halogen bulbs for LEDs is one of the easiest and most cost-effective upgrades. LEDs use up to 80% less energy and last significantly longer, which reduces maintenance visits and bulb replacement costs.
Bonus: LED lights also improve the overall look and brightness of the property — another tick for tenant appeal.
3. Add loft insulation (top-up or new) - From £500
Heat rises — and in under-insulated homes, much of it escapes through the roof. Topping up loft insulation to the recommended 270mm can dramatically improve thermal performance and reduce heating bills.
Long-term gain: Better insulation means lower EPC-rated costs and higher ratings (required for future lettings from 2025 onwards).
4. Seal draughts around windows and doors - From £250
Small gaps around doors, windows, and floorboards can lead to big energy losses. Professional draught-proofing can improve comfort, stop complaints, and reduce heating bills — especially in older properties.
Quick win: It’s one of the cheapest ways to improve thermal performance without major renovation.
5. Upgrade to a smart thermostat - From £300
A smart thermostat allows tenants to manage heating more efficiently, even remotely via their phones. It’s a modern touch that can reduce energy use, improve tenant satisfaction, and help justify higher rents.
Landlord tip: Retain admin access to prevent overheating and manage settings between tenancies.
6. Replace old appliances with energy-efficient models - From £600
Swapping out old white goods like fridges, washing machines or electric heaters for A-rated (or better) appliances reduces electricity usage and repair calls. Tenants are also increasingly looking for “green” appliances when renting.
Pro insight: Energy-efficient appliances can help differentiate your property in a crowded rental market.
