Energy efficiency is fast becoming one of the most important issues in the UK property market – and rental homes are firmly in the spotlight. With rising energy prices, evolving legislation, and eco-conscious tenants, improving rental property EPC ratings isn’t just a nice-to-have – it’s a must.
For landlords in Hertfordshire and across the Country Properties network, understanding what an EPC rating means and how to improve it is key to staying competitive and compliant. In this guide, we break down what an EPC involves, why it’s more important than ever, and how you can improve it to future-proof your rental property.
What is an EPC?
An Energy Performance Certificate (EPC) measures a property’s energy efficiency on a scale from A (most efficient) to G (least efficient). It considers elements like insulation, heating systems, double glazing, and lighting. All rental properties in the UK must have a valid EPC before being let, and it must be made available to tenants.
The certificate is valid for 10 years, but if you make improvements, you can renew it sooner to reflect your property’s upgraded efficiency.
Why EPC ratings matter more than ever
The government has proposed that all rental properties should have a minimum EPC rating of C by 2028 (subject to confirmation). Even though this has yet to be finalised, it signals a clear direction. Landlords who act now will be ahead of the curve, rather than rushing at the last minute.
Tenants, too, are increasingly aware of the benefits of an energy-efficient home. Lower utility bills and a warmer, more comfortable living space are big selling points.
If you’re renting property in Hertfordshire, particularly in rural areas where homes may be older, improving energy efficiency could make a huge difference to your property’s appeal.
Benefits of improving rental property EPC
- Attract better tenants: Tenants are actively looking for warm, efficient homes with lower bills
- Charge a premium: Higher energy performance often supports higher rental values
- Future-proof against legislation: Stay ahead of government requirements and avoid costly retrofits
- Boost property value: Energy-efficient homes tend to sell for more
- Reduce voids: Tenants are more likely to stay long-term in well-maintained, comfortable properties
Where to start: simple changes that make a big impact
Improving rental property EPC doesn’t always mean a full renovation. There are smaller, cost-effective upgrades that can significantly boost your rating:
- Install LED lighting: Replacing halogen or incandescent bulbs with LED can add points to your EPC
- Insulate the loft: Many homes fall short here, and the payback is fast
- Seal drafts: Use draft-proofing strips around doors and windows
- Install smart thermostats: Improves heating efficiency and tenant appeal
- Use thermostatic radiator valves (TRVs): Offers better control over individual room heating
Bigger upgrades that deliver better returns
If you’re planning a longer-term strategy to improve your EPC rating, consider:
- Upgrading the boiler: Modern condensing boilers are far more efficient
- Cavity wall insulation: Especially in properties built before the 1990s
- Double or triple glazing: A significant improvement in thermal retention
- Solar panels: A more expensive investment, but tenants appreciate renewable energy options
Each of these upgrades can push your EPC rating up, and some may be eligible for government grants or green funding support.
Understanding your EPC report
The EPC report doesn’t just give a letter grade. It also includes a list of recommended improvements, their estimated costs, and potential energy savings. It’s a helpful starting point for any landlord looking to improve their rating.
Pay attention to the “potential rating” – this shows how much you could improve your property’s energy efficiency with the recommended changes.
Future-proofing means planning ahead
Improving your rental property EPC isn’t just about passing legislation. It’s about making your property more resilient to change, more desirable to tenants, and more valuable in the long term.
Hertfordshire landlords should also consider how energy efficiency fits into wider maintenance and refurbishment plans. For example, if you’re already upgrading a kitchen or bathroom, think about insulation or energy-saving appliances at the same time.
What about listed or older buildings?
Many homes in towns like Hitchin, Baldock, and Royston are period properties. These can be harder to bring up to modern energy standards. Listed buildings may be exempt from certain requirements, but you’re still encouraged to do what you can.
Secondary glazing, draft exclusion, and internal insulation are often acceptable in heritage settings – and even small upgrades will improve your EPC.
Always check with your local authority before making significant changes to listed or conservation-area homes.
What landlords in Hertfordshire need to know
The property market in Hertfordshire is competitive. Landlords who invest in energy efficiency are setting themselves apart.
Some key local considerations:
- Country homes may lack insulation – a retrofit could make a dramatic difference
- Urban homes might benefit from solar panel installations, particularly south-facing roofs
- Letting agents increasingly promote EPC ratings in listings, making good ratings a marketing advantage
As tenant expectations shift, a low EPC rating may even put some applicants off before they view.
EPC myths debunked
- “It’s too expensive”: Some changes are very affordable and have high ROI
- “My tenants won’t care”: Many do – especially young professionals and families
- “It’s not urgent”: Waiting could mean higher costs and stress later on
- “You can’t do much with old homes”: Every property has improvement potential
