How many EPC points for installing double glazing ?
When it comes to making your home more energy-efficient, installing double glazing is a popular choice. While it can be quite an investment, many homeowners wonder how much it will actually improve their Energy Performance Certificate (EPC) rating. This article will explore the impact of double glazing on your EPC score, its costs, benefits, and alternatives to help you make an informed decision.
Key Takeaways
Double glazing can add 2-3 points to your EPC rating, depending on your current windows and other factors.
The cost of installing double glazing ranges from £2,000 to £6,000 for a typical home.
In conservation areas or for leaseholders, installing double glazing may not be allowed, making secondary glazing a viable alternative.
Other improvements like loft insulation, upgrading your boiler, and energy-efficient lighting can offer more EPC points for less money.
Consulting an EPC assessor and exploring government grants can help you decide the best steps to improve your home's energy efficiency.
Understanding EPC Ratings and Double Glazing
What is an EPC Rating?
An Energy Performance Certificate (EPC) rates a home's energy efficiency on a scale from A (very efficient) to G (inefficient). EPCs rate a home from A (very efficient) to G (inefficient). They provide insights into how costly it will be to heat and light your property and its carbon dioxide emissions.

How Double Glazing Affects EPC Ratings
Double glazing can improve your EPC rating by adding 2-3 points. It works by creating a sealed air gap that helps reduce noise and acts as an extra layer of insulation. This helps lower the amount of heat that escapes, keeping your home at a more comfortable temperature.
Common Misconceptions About Double Glazing
Many people think that installing double glazing will significantly boost their EPC rating. However, the improvement is usually modest. If your goal is to improve your EPC rating at a lower cost, there are other areas where you can spend less and achieve more points.
Double glazing is often seen as a major upgrade, but its impact on EPC ratings is relatively small. Consider other energy-saving measures for a more cost-effective improvement.
Cost-Benefit Analysis of Double Glazing
Initial Costs of Double Glazing
Installing double glazing can be quite expensive, with costs ranging from £4,000 to £6,000 for a typical three-bedroom terraced house. However, the investment can be worthwhile in the long run. The initial cost may vary depending on the type of windows and the specific requirements of your property.
Long-term Savings and Benefits
Double glazing helps reduce heat loss, making your home more energy-efficient. This can lead to lower energy bills and a more comfortable living environment. Over time, the savings on heating costs can offset the initial investment. Additionally, double glazing can last up to 20 years, providing long-term benefits.
Comparing Double and Triple Glazing
When choosing between double and triple glazing, it's important to consider the cost difference. Triple glazing is generally more expensive but offers better insulation. However, the cost analysis shows that the additional benefits may not always justify the higher price. For most homes, double glazing provides a good balance between cost and energy efficiency.
Alternative Ways to Improve EPC Ratings
Loft and Wall Insulation
Insulating your loft and walls can make a big difference in your home's energy efficiency. Loft insulation can prevent up to 25% of heat loss, while wall insulation can also significantly reduce heat loss. Both options can improve your EPC rating by several points.
Upgrading Your Boiler
Using a modern and efficient boiler can greatly improve your EPC rating. Older boilers tend to use more energy, while newer models are more efficient and can increase your EPC score by up to 40 points. Consider looking into government schemes like the Boiler Upgrade Scheme for financial assistance.
Energy-Efficient Lighting
Switching to energy-efficient lighting, such as LED bulbs, is a simple way to add a few points to your EPC rating score and is relatively inexpensive.
Incorporating renewable energy options is an excellent way to improve your EPC rating from D to B or even higher . Renewable energy sources such as solar panels and wind turbines can make your home more energy-efficient and eco-friendly.
By making these changes, you can significantly improve your EPC rating and make your home more energy-efficient.
Challenges and Considerations

Restrictions in Conservation Areas
If you live in a conservation area, you might face restrictions on installing double glazing. These areas aim to preserve the historical and architectural significance of buildings. Therefore, any changes, including window upgrades, often require special permissions. It's essential to check with your local council before making any modifications.
Leaseholder Limitations
For those who are leaseholders, installing double glazing can be more complicated. You usually need to get approval from the freeholder. This can sometimes lead to delays or even refusals. Always review your lease agreement and consult with the freeholder to understand your options.
Secondary Glazing as an Alternative
If you encounter restrictions or limitations, secondary glazing can be a viable alternative. This involves adding a second layer of glazing inside your existing windows. While it may not be as effective as double glazing, it still offers improved insulation and can be a good compromise in areas with strict regulations.
When considering upgrades, always weigh the benefits against potential challenges to make an informed decision.
Expert Recommendations and Advice
Consulting an EPC Assessor
To get the most accurate EPC rating, it's best to consult a professional EPC assessor. They can provide a detailed report on your property's energy efficiency and suggest specific improvements. Consulting an expert ensures you get the most accurate assessment and tailored advice for your home.

Government Grants and Schemes
There are various government grants and schemes available to help with the cost of energy efficiency improvements. These can significantly reduce the initial outlay for upgrades like double glazing. Check if you qualify for any of these schemes to make your home more energy-efficient without breaking the bank.
Making Informed Decisions
When planning energy efficiency upgrades, it's crucial to make informed decisions. Consider the long-term benefits and potential EPC score improvements. For example, going from no insulation to 300 mm will increase the EPC score by around 8 or 9 points. Weigh the costs against the benefits to ensure you're making the best choices for your property.
Remember, improving your EPC rating not only makes your home more energy-efficient but can also increase its market value and appeal to potential buyers or tenants.
Impact on Property Value and Marketability
EPC Ratings and Property Value
Improving your home's EPC rating can significantly boost its market value. A study by Rightmove found that sellers who upgraded their property's EPC rating from a D, E, or F to a C saw up to a 16% increase in their sale price. Homes with high energy ratings are more attractive to buyers because they promise lower energy bills and better living conditions.
Attracting Potential Buyers or Tenants
Properties with better EPC ratings are more appealing to potential buyers and tenants. People are more likely to rent a property if they know it has a high energy rating and is well insulated, saving them more money on monthly cooling and heating costs. This makes your property stand out in a competitive market.
Long-term Investment Benefits
Investing in energy-efficient upgrades like double glazing can offer long-term benefits. Not only does it reduce heat loss, but it also makes your home more marketable. Over time, these improvements can pay off by increasing your property's value and making it easier to sell or rent out.
Conclusion
In conclusion, while installing double glazing can improve your home's energy efficiency, it may not significantly boost your EPC rating. The upgrade typically adds around 2-3 points, which might not justify the high costs involved. If your primary goal is to enhance your EPC rating, you might want to explore other, more cost-effective measures. Options like loft insulation, upgrading your boiler, or even switching to LED lighting can offer better returns on investment. Always consider your specific circumstances and consult with a professional to make the most informed decision for your home.
