Shape Your Perfect Home
Double Glazing
Windows are one of the most important features of any home. Not only do they offer natural light and ventilation, but they also play a key role in energy efficiency, security, and overall comfort. If you're a UK homeowner looking to upgrade your windows to double glazing, you may be considering both the costs involved and the financial support options available to help make the upgrade more affordable. Luckily, there are grants available through the government's ECO4 Scheme, as well as various finance options to assist with new windows installations.
Why Should You Upgrade to Double Glazing?
Upgrading to double glazing windows can have significant benefits for your home:
-
Improved Energy Efficiency: Double glazing helps to reduce heat loss by trapping air between two panes of glass, keeping your home warmer in winter and cooler in summer.
-
Lower Energy Bills: With improved insulation, your home will need less heating, potentially reducing your energy bills.
-
Noise Reduction: Double glazing can help to reduce external noise, making your home more peaceful.
-
Increased Property Value: Modern windows enhance the aesthetics of your home, which could improve its market value.
-
Enhanced Security: Double glazing windows are more difficult to break, providing an additional layer of protection for your property.
The Cost of New Windows in the UK
The average cost for installing new double glazing windows can vary depending on several factors, including the size of your home, the number of windows you need to replace, the type of glazing you choose, and the complexity of installation. Here’s a rough guide to help you understand the costs:
-
Standard uPVC Double Glazed Windows: Typically range between £300 and £700 per window, depending on size and quality.
-
Wooden Double Glazed Windows: These tend to be more expensive, with costs ranging from £600 to £1,000 per window.
-
Aluminium Windows: The cost of aluminium windows can range from £500 to £1,200 per window, but they are known for their durability and slim frames.
For a standard three-bedroom home, the total cost for replacing all windows can range from £3,000 to £7,000, depending on the above factors. It's always recommended to get multiple quotes from certified installers to ensure you're getting a competitive price.
How to Qualify for the ECO4 Scheme
The ECO4 (Energy Company Obligation) scheme is a government initiative that helps low-income households and those in fuel poverty make energy-saving improvements to their homes. Under this scheme, you may be eligible for financial assistance to replace single-glazed windows with more energy-efficient double glazing.
Who Qualifies for the ECO4 Scheme?
To qualify for ECO4 grants for new double glazing, you generally need to meet one of the following criteria:
-
Income-Based Criteria:

You may also qualify if you are in receipt of certain benefits like Universal Credit, Pension Credit, or Child Tax Credit.

Vulnerable Households:
-
If you are over the age of 65, have a disability, or are a parent with young children, you may be eligible for assistance under the ECO4 scheme.
-
-
Private Rental Sector:

UPVC - Doors
Upgrading your property with new uPVC doors is a fantastic way to enhance its aesthetic appeal, improve security, and boost energy efficiency. If you're a homeowner in the UK, you might be wondering about the financial implications of such an upgrade. Fortunately, the government offers funding opportunities under the ECO4 Scheme that can help with the cost. In this post, we’ll explore the many benefits of installing new uPVC doors, explain how to qualify for financial support through the ECO4 Scheme, and give an idea of the average cost of new uPVC doors and installation.
One of the standout benefits of uPVC doors is their excellent insulation properties. Modern uPVC doors are designed with advanced materials that help to keep heat inside your home and prevent drafts. As a result, you'll notice reduced energy bills since your home will retain heat better in winter and stay cooler in summer. The added insulation can significantly lower your reliance on heating and cooling systems, which is not only cost-effective but environmentally friendly too.
Security is a top concern for homeowners, and uPVC doors are known for their robustness. They are often equipped with multi-point locking systems, which offer higher security than traditional wooden doors. Additionally, uPVC doors are incredibly durable and resistant to weathering, which makes them a good long-term investment for protecting your home and family.
Unlike wooden doors that may require regular sanding, painting, or staining, uPVC doors require very little maintenance. They are weather-resistant and will not warp, rot, or fade over time, making them ideal for homeowners who want a low-maintenance solution that still looks great for years to come.
uPVC doors come in a variety of styles and finishes, allowing you to choose a design that complements the overall aesthetic of your home. Whether you want a modern, sleek look or a more traditional style, there’s a uPVC door to suit your preferences. New doors can give your home an instant facelift and increase its value should you choose to sell in the future.
The thick, insulated panels of uPVC doors help to reduce external noise, making your home quieter. Whether you live on a busy street or near a noisy area, new uPVC doors can provide a sense of tranquility inside your home.
The Energy Company Obligation (ECO4) Scheme is a government initiative aimed at helping homeowners in the UK improve their homes’ energy efficiency. It provides financial support for home improvements, including the installation of energy-efficient doors. To qualify for new uPVC doors under the ECO4 Scheme, homeowners generally need to meet certain criteria.
If you or anyone in your household receives certain means-tested benefits such as Universal Credit, Pension Credit, Income Support, or Jobseeker’s Allowance, you could be eligible for funding to replace old doors with energy-efficient uPVC options. These benefits are aimed at households on low incomes or those in vulnerable situations. Both homeowners and private tenants may be eligible for the scheme, but tenants will need the permission of their landlord before proceeding with any installations. The property must be located in the UK and be your primary residence. The house should also be at least five years old, and any previous grants for energy-efficient measures should not have been used.
Once you’ve determined that you meet the eligibility criteria, you can apply for the ECO4 Scheme through a registered installer or energy supplier. They’ll assess your property and determine the most appropriate improvements based on your home's energy performance. The application will be reviewed, and if you qualify, you'll receive funding for the installation of new uPVC doors (along with any other energy efficiency upgrades your home might need).
When it comes to the cost of replacing doors with uPVC models, the price can vary depending on the quality, design, and size of the door, as well as the complexity of the installation. On average, you can expect to pay between £400 to £700 for a standard uPVC front door. Bespoke or designer uPVC doors typically range from £700 to £1,200, and sliding patio or French doors can cost anywhere from £1,000 to £2,000.
On top of the cost of the doors themselves, you'll also need to factor in installation costs. Professional installation typically costs between £150 to £300 per door, depending on the complexity of the job. If you're replacing several doors, there may be discounts available for bulk installations.
While these costs can add up, it’s important to remember that energy savings and long-term durability can offset these initial expenses. And for those who qualify under the ECO4 Scheme, much of the cost may be covered, making it a highly affordable option.
Fitting new uPVC doors in your home offers a wide range of benefits, from energy efficiency and security to aesthetic appeal and low maintenance. If you're a homeowner in the UK, you may be able to take advantage of the ECO4 Scheme, which helps with the costs of upgrading your property to more energy-efficient options. By qualifying for funding, you can improve your home's comfort and energy performance while keeping costs manageable.
Whether you're looking to enhance your home's look, save on energy bills, or increase security, new uPVC doors are an excellent investment. Take advantage of the available funding and get in touch with a qualified installer today!
