Unlock Higher Returns: Energy-Efficient Upgrades Every HMO Landlord in London Should Prioritise

Rising energy bills. Changing legislation. Eco-conscious tenants.

If you’re a landlord in London managing HMO or short-term rental properties, making your investments energy-efficient isn’t just a smart move—it’s essential for staying competitive, compliant, and profitable.

At 20Property Management, we help landlords maximise rental income through expert HMO property management, Airbnb management, and hands-off, full-service solutions that make letting seamless—from listing to 24/7 guest support. One of the key ways to improve rental yields and future-proof your portfolio? Start with your Energy Performance Certificate (EPC).

Here’s your luxury guide to getting started.

Why Energy Efficiency Should Be on Every London Landlord’s Radar

With proposals in place to raise the minimum EPC requirement to C by 2025 for new tenancies, and all tenancies by 2028, landlords need to act now to stay ahead. The government is already enforcing a minimum EPC rating of E, and further tightening is on the horizon. But it’s not just about regulations.

Improving your property’s EPC can:

• Attract eco-conscious tenants who are willing to pay for sustainability.

• Lower running costs and boost your net rental income.

• Increase property value and long-term profitability.

• Future-proof your portfolio before the demand for compliant homes surges.

Yet despite the growing urgency, over 50% of landlords are unsure where to begin—and that’s where we come in.

Where to Begin: Step-by-Step Energy Efficiency Improvements

Whether you're managing a Victorian terrace or a modern conversion, here’s how to start upgrading your HMOs for better energy performance—and better returns.

1. Review Your Current EPC

Start with your property’s Energy Performance Certificate—this document gives you a clear snapshot of your current rating (from A to G), and includes tailored recommendations for improvement.

Can’t find your EPC? You can easily search by postcode on the UK government’s EPC register for properties in England and Wales.

At 20Property Management, we assist landlords in reviewing EPC reports and developing a bespoke plan to improve them—aligned with your budget, goals, and rental strategy.

2. Upgrade Key Features That Impact EPC Ratings

There’s no one-size-fits-all fix, but certain upgrades deliver consistent value—especially for older properties common across London. Here’s what to consider:

Insulation First: The ‘Fabric’ Approach

The government recommends starting with insulation—the "fabric first" method. Focus on:

• Loft insulation (aim for 270mm thickness or more)

• Cavity or solid wall insulation

• Floor insulation (especially in period properties)

These changes can drastically cut heat loss and are often the most cost-effective first step.

Efficient Boilers & Heating Controls

Older boilers are energy drains. Replacing them with modern condensing models and smart thermostats can significantly lift your EPC rating—and reduce tenant energy costs.

Double or Triple Glazing

Not yet double glazed? That upgrade alone can boost your EPC score by 10 points. Already double glazed? Triple glazing offers additional insulation and soundproofing—a bonus for city-based HMOs.

Smart Lighting & Energy-Efficient Appliances

Switch all lighting to LED bulbs—an easy, inexpensive way to improve your rating. Then review appliances: look for A-rated fridges, washing machines, and dishwashers.

Need support sourcing and staging energy-efficient furniture and appliances? Our team at 20Property Management offers full-service furnishing and interior design, tailored for short-term lets and HMOs.

Renewable Energy Where Feasible

Installing solar panels or air/ground source heat pumps may sound ambitious—but these upgrades future-proof your portfolio and appeal to eco-conscious tenants.

Our property management experts can advise you on when it makes sense financially and help you access available grants or incentives.

Install Smart Meters

Tenants want transparency. Smart meters show real-time energy usage, encourage mindful consumption, and help flag inefficient systems before they become costly.

3. Budget & Funding: Know the Costs, Plan Strategically

Once you’ve identified the right improvements, the next step is budgeting.

We recommend:

• Requesting a professional energy assessment.

• Getting multiple quotes for work.

• Exploring government grants, energy efficiency schemes, or green mortgage incentives.

20Property Management offers trusted contractor connections and project management services to streamline this process—so your upgrades are handled efficiently and on-budget.

The Benefits Go Beyond Compliance

Yes, you’ll get ahead of legislation. But the real advantages of energy efficiency lie in profitability and appeal.

• Higher-quality tenants seek sustainable, well-maintained homes.

• Lower void periods—especially if you’re using Airbnb or short-term rental models.

• Reduced maintenance issues from outdated systems.

• Increased market value if you decide to refinance or sell.

We manage properties across London and the UK that benefit from green upgrades—not just because they’re compliant, but because they perform better on every level.
