Upgrading your home’s energy efficiency doesn’t just mean new boilers or insulation—it can also include stylish and practical changes like uPVC doors and double glazing. Both are excellent options for homeowners who want to improve their home’s comfort, security, and energy performance. And if you're a UK homeowner on a qualifying income, the ECO4 Scheme (Energy Company Obligation) can help make these upgrades more affordable.
In this blog post, we’ll cover how you can access these upgrades through the ECO4 Scheme, the costs involved, and the benefits of upgrading to uPVC doors and double glazing.

uPVC Doors and Double Glazing: Part of the ECO4 Scheme
The ECO4 Scheme is a government initiative that provides financial help to homeowners and tenants to install energy-efficient products like insulation, efficient heating, and energy-saving doors and windows. This includes uPVC doors and double glazing, both of which can dramatically improve the thermal performance of your home, keeping you warmer in winter and cooler in summer—reducing your overall energy bills.
Who Qualifies for the ECO4 Scheme?
To qualify for the ECO4 Scheme and access grants for uPVC doors or double glazing, you must meet certain criteria. The main qualifying factors are:
Income-based Criteria: The scheme targets households with lower incomes, including those receiving government benefits such as Universal Credit, Pension Credit, or Child Tax Credit.
Property Type: The property must be domestic, and typically, homes built before 1990 are more likely to qualify as they are often less energy-efficient.
Energy Efficiency: Homes with a low Energy Performance Certificate (EPC) rating (such as EPC rating D or below) are more likely to be eligible for support under the ECO4 Scheme.
The Benefits of uPVC Doors and Double Glazing
uPVC Doors
uPVC doors offer several advantages, making them a popular choice for homeowners looking to improve both their home’s aesthetics and energy efficiency:
Energy Efficiency: uPVC doors are known for their great insulation properties. By reducing heat loss, they help maintain a stable temperature inside your home, cutting down on heating costs during colder months.
Low Maintenance: Unlike wooden doors, uPVC doesn’t require regular painting or varnishing. It’s also resistant to warping, cracking, and fading, ensuring a long-lasting, attractive finish.
Security: uPVC doors are secure, featuring multi-point locking systems that provide enhanced security for your home.
Cost-Effective: uPVC doors are generally more affordable than wooden or aluminium doors while still offering high levels of insulation and durability.
Double Glazing
Installing double glazing under the ECO4 Scheme is another fantastic way to improve your home’s energy efficiency. Double-glazed windows consist of two layers of glass with a gap in between, providing better insulation than single-glazed windows. Here’s why it’s a wise investment:
Better Insulation: Double glazing prevents heat from escaping in winter and keeps your home cooler in the summer by reducing heat transfer. This can lead to significant savings on your energy bills.
Noise Reduction: Double glazing also helps reduce noise from the outside, making your home more peaceful, especially if you live in a busy area.
Increased Property Value: Homes with double glazing are more attractive to potential buyers due to their superior insulation, security, and energy efficiency.
Reduced Condensation: Double glazing helps to reduce condensation on windows, which can lead to damp and mould problems.
How Much Do uPVC Doors, Double Glazing, and Installation Cost?
The costs for uPVC doors and double glazing can vary depending on factors like size, design, and the company you choose, but here’s an overview of what to expect:
uPVC Doors: A standard uPVC door can cost between £400 to £800, depending on the style and specifications. If you’re looking for a modern bi-fold door, these can range from £1,000 to £3,000.
Double Glazing: The cost of replacing windows with double glazing can vary significantly based on the size of the windows and the number of panes needed. Typically, double glazing for a standard window costs between £300 to £600 per window, including installation.
Installation: Installation fees typically range from £150 to £350 for a single door or window, though this can rise depending on the complexity of the job or if additional work is needed.
While these costs may seem high, the financial savings you’ll enjoy through lower energy bills can make the investment well worth it. And with the help of the ECO4 Scheme, you could get these upgrades at a discounted rate or even for free, depending on your eligibility.
