How UPVC Windows and Doors Can Cut Your Winter Energy Bills
As energy prices remain unpredictable and winter approaches, many homeowners across Surrey are looking for practical, cost-effective ways to make their homes warmer and more efficient. One of the simplest, most affordable upgrades you can make is installing modern, energy-efficient UPVC doors and windows.
Far from the basic white frames of the past, today’s energy-efficient UPVC doors and windows are high-performance, stylish, and designed to help you save money all year round. Our UPVC windows Farnham company are going to dive in to how they can make a real difference to your comfort and your energy bills:
The Technology Behind Energy-Efficient UPVC Doors & Windows
UPVC has come a long way since its early days. Modern systems use multi-chambered frames that trap pockets of air within the structure - a natural insulator that prevents heat from escaping. Paired with A-rated double or triple glazing, this design helps to keep warm air inside and cold air out, even during the chilliest Surrey winters.
Many products now achieve U-values as low as 0.8 W/m²K, rivalling far more expensive materials. According to the Energy Saving Trust, replacing single glazing with energy-efficient windows can save a typical semi-detached home around £140 a year in heating costs.
At Chartwell Classic Windows, every UPVC window and door we fit is chosen for its performance and durability. Our systems are fully sealed, weather-resistant, and designed to meet the latest building regulations for energy efficiency.

If you’re seeking affordability and low maintenance, UPVC is hard to beat. It provides the best value for everyday family homes, delivering solid performance without a premium price tag.
How Much Could You Save with Energy-Efficient UPVC Doors and Windows?
The savings you’ll see depend on your property type, glazing level, and how old your existing windows are. But with rising fuel costs, even modest improvements can pay off quickly.
According to the Energy Saving Trust, installing new double-glazed UPVC windows can reduce heat loss by up to 50 % compared with single glazing. That could translate to hundreds of pounds saved each year for detached or larger homes.
Because UPVC requires no repainting or sealing, you also save on maintenance and upkeep costs over its lifetime. Factor in improved comfort, reduced drafts, and less outside noise, and the return on investment becomes even clearer.
Double or Triple Glazing - Which Is Right for You?
Many homeowners ask our double glazing installers Surrey company whether triple glazing is worth the extra cost. The answer depends on your home’s insulation levels and exposure to the elements.
- Double glazing remains the most popular choice, offering excellent value and strong insulation.
- Triple glazing provides superior noise reduction and improved U-values, ideal for homes on busy roads or exposed sites.
At Chartwell Classic Windows, we’ll help you compare the options and recommend the right balance between energy performance and budget. All our glazing units include Low-E coatings and argon gas fills, enhancing insulation while keeping your interiors bright and clear.
The Long-Term Value of Choosing UPVC
Beyond energy savings, UPVC offers a range of long-term benefits. It’s weather-resistant, does not rot, rust, or fade, and requires nothing more than a quick wipe with soapy water to stay looking new.
Unlike older plastic frames, today’s high-quality UPVC windows come in a variety of colours and finishes, including anthracite grey, black, and woodgrain effects - perfect for blending with both modern and period homes.
They also offer exceptional security, with multi-point locking mechanisms and reinforced frames that protect your home without compromising on style.
When you consider the decades of performance, low upkeep, and proven energy savings, UPVC represents one of the best value investments for homeowners preparing for winter.
Frequently Asked Questions About UPVC Windows and Doors
How much can UPVC windows save on energy bills?
Savings depend on your home’s size and the condition of your existing windows, but the Energy Saving Trust estimates that replacing single glazing with A-rated UPVC double glazing can save the average UK household around £140 per year. In larger or detached homes, that figure can be even higher, especially with modern energy-efficient glazing.
Are UPVC windows and doors still a good investment?
Yes. Despite being one of the most affordable materials, modern UPVC windows and doors offer outstanding performance, long lifespan, and minimal upkeep. Their excellent insulation helps cut energy use, and their durability means they can last 20–30 years or more, providing excellent long-term value.
What makes UPVC windows energy efficient?
UPVC frames contain multi-chambered designs that trap air to form a natural thermal barrier. When combined with Low-E glass, argon gas filling, and professional installation, they drastically reduce heat loss, keeping your home warmer in winter and cooler in summer.
Do UPVC windows suit traditional homes?
Yes. Although once associated with modern builds, today’s UPVC windows come in a wide range of finishes, including woodgrain effects and heritage colours, that blend seamlessly with older or character properties. This makes them ideal for Surrey cottages and period homes needing improved efficiency without changing their look.
Are UPVC windows secure?
Definitely. All Chartwell Classic Windows products include multi-point locking systems, reinforced frames, and toughened glazing as standard. UPVC is inherently strong and impact-resistant, offering reliable protection for your home and peace of mind for your family.
What’s the difference between double and triple glazing for UPVC windows?
Double glazing provides excellent insulation and is the most cost-effective choice for most homes. Triple glazing offers extra noise reduction and slightly better U-values, which can be beneficial for properties near busy roads or in exposed rural areas. Chartwell can help you choose the best option for your needs.
Do UPVC windows need maintenance?
UPVC is a low-maintenance material. Simply wipe the frames with a mild soap solution every few months to remove dust or residue. Unlike timber, UPVC never needs painting, sealing, or varnishing, and it’s resistant to rot, rust, and corrosion.
Are UPVC windows environmentally friendly?
Yes. High-quality UPVC is fully recyclable and can be reused multiple times without losing performance. Because it lasts for decades and reduces heat loss, UPVC actually lowers your home’s carbon footprint over its lifetime.
