As many of you will have seen in the news, the UK government is pushing to increase the minimum Energy Performance Certificate (EPC) rating for private rental properties from an E to a C by 2030. It’s a move designed to make homes more energy efficient, helping to reduce carbon emissions and keep energy bills lower for tenants, but there’s a lot of debate about whether it will actually happen in its current form. With a general election due before 2030, it’s entirely possible the legislation could be watered down, postponed, or scrapped altogether by the next party (if there is a change, which we would put money on happening).
However, if you’re a landlord, it’s wise to stay informed and start planning now. Improving your property’s energy efficiency can deliver a range of benefits, from reduced running costs to a better experience for your tenants. Plus, tackling upgrades early means you can spread out the costs and avoid last-minute stress if the regulations do go ahead as planned.
In this blog post, we’ll take a deep dive into what’s changing, why it’s changing, and what you can do to help boost your property’s EPC rating. We’ll also share our thoughts here at Front Door Lettings on the likelihood of these new rules coming into effect—and what it might mean for your rental portfolio in the long run.
What’s Changing and Why?
Current Rules
At present, a landlord must ensure any rented property has an EPC rating of at least E. This has been the benchmark for a few years now, and any property that falls below an E rating is considered non-compliant. That means you either need to carry out improvements to bring it up to standard or face restrictions on letting the property, plus possible financial penalties.
Proposed Regulations
The government’s proposal is to increase that minimum EPC rating to a C by 2030 for all private rented properties. There’s some logic behind this: homes with higher energy efficiency use less electricity and gas, which lowers their carbon footprint. Tenants also benefit from lower utility bills, a significant consideration given rising energy costs.
However, it’s also a big leap for landlords, many of whom are still catching up on the costs of meeting the E rating threshold. And because these changes aren’t set to take effect until 2030, there’s ample time for them to be amended, postponed, or even removed, particularly if a new government with different priorities comes into power.
Why the Uncertainty?
The possibility of a new government post-election, coupled with the sheer economic strain on landlords, suggests we could see changes to the legislation itself. Plenty of voices in the property industry have called for a more gradual approach, or for certain types of properties, particularly older or listed buildings, to be exempt from the new rules. We’re also seeing ongoing debates about whether some properties could be given more time or different targets if they can’t feasibly reach a C rating without extensive renovation costs.
At Front Door Lettings, we believe the push for more energy-efficient homes is generally a good thing—tenants like it, and it can improve the long-term value of your property. But we also recognise that many landlords could face significant costs, so we anticipate either more exemptions or at least some flexibility on the 2030 deadline.
How to Improve Your EPC
Whether the new rules arrive in 2030 or later, it’s useful to know how you can boost your property’s EPC rating. Many improvements are relatively straightforward, while others require a more substantial investment. Below, we’ll look at some of the most common energy efficiency upgrades – and how they can help push up your score.
1. Insulate, Insulate, Insulate
Insulation is often the first thing that comes to mind when talking about energy efficiency, and for good reason. A well-insulated home retains heat more effectively, reducing the need for constant heating in the colder months. As a result, your tenants’ energy bills come down, and your property’s carbon footprint shrinks.
- Loft Insulation:
If your rental has a loft or attic space, installing loft insulation can be a cost-effective way to cut heat loss. According to Energy Saving Trust figures, proper loft insulation can pay for itself in as little as a couple of years, thanks to the savings on heating bills. Good insulation also helps regulate the temperature in the property year-round. - Cavity Wall Insulation:
For homes built with cavity walls (common in properties built after the 1920s), filling those cavities with insulation material is another big win. This process is usually straightforward and can dramatically improve a property’s EPC rating. - Solid Wall Insulation:
Older properties might have solid walls rather than cavity walls, which can be more expensive to insulate. You’ll typically have to choose between internal or external solid wall insulation. While pricier, it can bring a significant uplift in your rating. Bear in mind the property’s aesthetic: external insulation can alter the appearance, so planning permission may be required in some cases.
2. Upgrade Heating Systems
The heating system is one of the largest contributors to a home’s energy efficiency score. An outdated boiler or poorly maintained system can drag your EPC rating down significantly.
- High-Efficiency Boilers:
Modern condensing boilers can make a huge difference in cutting energy usage and improving comfort. They capture and reuse much of the heat that would otherwise escape via the flue in older systems. This lower energy consumption translates directly into a higher EPC score. - Smart Thermostats and Zoning
Smart thermostats (think Nest or Hive) and thermostatic radiator valves allow tenants to control heating in real-time and only use it when needed. Zoning your heating system—where certain areas of the house can be heated independently—can further reduce waste and bump up your EPC rating. - Underfloor Heating:
Underfloor heating is more efficient than traditional radiators in many cases because it distributes heat evenly. However, it’s not always the most cost-effective upgrade, especially if you need to rip up floors to install it. If you’re planning a renovation or significant refurb, it’s worth considering at that stage.
3. Focus on Windows and Doors
Poorly sealed doors and windows are massive culprits when it comes to heat loss. Even if your walls and loft are well insulated, old or single-glazed windows can let out a surprising amount of warmth. Replacing them with double- or triple-glazed units is one of the most direct ways to improve your EPC rating.
- Double or Triple Glazing:
Double-glazed windows provide insulation through a layer of inert gas between two panes of glass, while triple glazing adds an extra layer. Triple glazing is typically more expensive but can be useful in properties located in especially cold areas or busy urban centres (it also helps with noise reduction). - Draught-Proofing:
Sometimes, a full window or door replacement isn’t necessary. Installing high-quality draught excluders, sealing strips, or foam around the frames can cut down on heat loss at a fraction of the cost. Check for gaps under doors, letterboxes, and around window frames. - Energy-Efficient Doors:
If your external doors are old or damaged, replacing them with insulated doors can help a great deal. They often come with multi-point locking systems, which add an extra layer of security that tenants appreciate.
4. Lighting Upgrades
While lighting might not have as large an impact on EPC as heating or insulation, every little helps – especially if you’re right on the cusp of jumping to a higher rating.
- LED Bulbs:
Switching to LED or energy-saving bulbs can be one of the easiest wins. They use a fraction of the electricity of incandescent or halogen bulbs and can last for years before they need replacing. - Motion Sensors and Timers:
In communal areas or external spaces like porches and driveways, motion sensors or timer switches ensure lights only come on when needed. This reduces wasted energy, positively impacting the overall energy consumption of the property.
5. Consider Renewable Energy
Renewable energy systems such as solar panels, air-source heat pumps, and ground-source heat pumps often score highly on EPC assessments. They can, however, come with a higher initial cost.
- Solar Panels:
Installing solar panels can slash electricity bills and dramatically lower a property’s carbon footprint. Whether it’s financially worthwhile depends on factors like feed-in tariffs, local sunlight levels, and how much of the electricity your tenants will use during the day. - Heat Pumps:
Air-source or ground-source heat pumps extract heat from the outside air or ground and transfer it indoors. They can be very efficient but do require suitable space and, usually, a well-insulated building to function optimally. - Biomass Boilers:
Biomass boilers use organic materials like wood pellets or chips for fuel. They’re typically more common in rural settings where gas mains aren’t available. They can boost an EPC rating significantly, but you’ll need enough storage space for the fuel, and you’ll have to consider ongoing supply costs.
6. Ventilation and Moisture Control
Although not always the first thing that comes to mind for energy efficiency, proper ventilation can help prevent damp and mould, which can affect insulation performance and negatively impact your EPC rating in the long run.
- Extractor Fans:
Upgrading older extractor fans in kitchens and bathrooms to more efficient, lower-energy models can help maintain good air quality and reduce condensation without using excessive power. - Passive Ventilation:
Where appropriate, passive ventilation systems that don’t rely on electricity can keep fresh air circulating. This is especially useful if you’ve made the property more airtight with insulation.
7. Check for Grants and Funding
Some landlords might be able to take advantage of government schemes or local authority grants to help cover the cost of energy efficiency upgrades. These schemes come and go, so keeping up to date is crucial.
- Green Home Grants (Historical Examples):
The government has run grants in the past to help cover the cost of insulation, double glazing, and renewable energy installations. There might be new ones introduced in the future—especially if the push towards energy-efficient homes remains a priority. - Local Council Grants or Loans:
Some local councils offer low-interest loans or partial funding for improvements, particularly if your property meets certain criteria like being in a designated regeneration area or if it houses tenants who could be vulnerable to fuel poverty.
Front Door Lettings’ Thoughts
Here at Front Door Lettings, we’re supportive of efforts to make rental properties more energy efficient. It makes sense to ensure tenants are living in healthier, more comfortable homes that are cheaper to heat. And in the longer term, energy-efficient properties can command higher rents and experience fewer void periods.
That said, we know these proposed changes could present challenges, particularly if your portfolio includes older properties or properties that require extensive (and expensive) upgrades. We wouldn’t be surprised if the government introduces more exemptions for landlords who can demonstrate that reaching a C rating is prohibitively costly, or if the deadline is pushed back. If the political landscape shifts after the next election, these regulations could be revisited or replaced with something else entirely.
In short, the property sector is in flux, and we expect further clarity as 2030 draws closer. But it’s never too early to start planning, and if you’re in build at the moment, or refurbishing the property then futureproofing the house to a C will make sense anyway. Proactive improvements not only help you avoid compliance headaches later but also add real value to your property – whether in terms of tenant satisfaction or long-term investment growth.
