If you’re looking to sell or rent your property, a higher Energy Performance Certificate (EPC) rating can make a big difference. A better EPC score means lower energy costs, increased property value, and a more attractive listing for potential buyers or tenants.
Here’s a practical guide to improving your property’s EPC rating.
1. Upgrade Your Insulation
Poor insulation is one of the main causes of heat loss in homes.
- Loft Insulation: Adding or upgrading loft insulation is one of the easiest and most effective ways to boost your EPC score. Aim for at least 270mm of insulation material.
- Cavity Wall Insulation: If your property has uninsulated cavity walls, filling them with insulation can greatly improve energy efficiency.
- Solid Wall Insulation: Older properties may require internal or external solid wall insulation to meet modern energy standards.
2. Install a Modern, Energy-Efficient Boiler
Heating accounts for a large portion of a property’s energy use.
Replacing an old boiler with a modern condensing boiler or an air source heat pump can significantly enhance your EPC rating.
Tip: Choose a boiler with a high Energy Efficiency Rating and ensure your heating system is serviced regularly.
3. Replace Single Glazing with Double or Triple Glazing
Upgrading your windows:
- Reduces heat loss
- Minimizes draughts
- Improves your home’s overall thermal efficiency
Installing energy-efficient double or triple glazing will positively impact your EPC rating and can also reduce noise pollution.
4. Switch to Low-Energy Lighting
An inexpensive but effective improvement is switching to LED lighting throughout your property.
LEDs use up to 90% less energy than traditional incandescent bulbs and are noted on the EPC assessment.
5. Install Renewable Energy Systems
Investing in solar panels, solar water heating, or ground source heat pumps can dramatically improve your EPC rating.
Although the upfront cost can be higher, renewable technologies can:
- Reduce your energy bills
- Boost your property’s value
- Future-proof your home against energy regulations
6. Improve Hot Water Systems
Simple upgrades like installing an energy-efficient hot water cylinder or fitting a hot water jacket can help.
Also, consider smart thermostats and heating controls to optimize energy usage.
7. Draught-Proof Your Home
Sealing gaps around doors, windows, and chimneys is a low-cost way to prevent heat from escaping.
Professional draught-proofing services are available, but even DIY solutions can make a noticeable difference.
8. Upgrade to Smart Heating Controls
Fitting programmable thermostats, smart radiator valves, and zoned heating systems can boost your property’s energy efficiency.
Smart controls make heating more efficient by allowing you to adjust temperatures room-by-room.
Small Changes, Big Impact
Even a few low-cost changes — like loft insulation, LED lighting, and draught-proofing — can move a property’s EPC rating up one or two bands, making a big difference when selling or renting.
