Looking to reduce your energy bills this winter? Your windows and doors could be the key to significant savings. With UK households facing rising energy costs, upgrading to energy-efficient windows and doors can cut your heating bills by up to 20%.

Here’s how to make your home more energy-efficient and comfortable during the cold months.

Understanding Window Energy Ratings

The British Fenestration Rating Council (BFRC) rates windows from A++ to E, with A++ being the most energy efficient. The ratings take into account factors such as heat loss, air leakage, and solar gain capabilities, providing a comprehensive assessment of each window’s performance. 

Here’s what different ratings mean for your home:

Double and Triple Glazing: What’s the Difference?

Double Glazing: The Popular Choice

Double glazing uses two panes of glass with a gap of air between them to reduce heat loss. This design cuts heat loss by 50% compared to single-pane windows.

Most people save between £110 and £140 every year on their heating bills. You’ll also have less window condensation and reduced noise from outside.

• Reduces heat loss by 50% compared to single glazing

• Cuts energy bills by £110-£140 per year

• Minimises condensation and noise pollution

Triple Glazing: Extra Protection

Triple glazing adds a third pane of glass, which makes it 35% more effective at keeping heat in than double glazing. It’s particularly effective for rooms that face north or homes in cold, exposed areas.

It costs more initially but can be a good choice if you live somewhere particularly cold or near a busy street.

• Provides 35% better insulation than double glazing

• Ideal for north-facing windows

• Perfect for homes in exposed locations

Making Your Doors More Energy Efficient

Modern Doors

Window World’s composite doors combine advanced materials and innovative design to revolutionise home energy efficiency. Unlike traditional wooden doors that often warp and leak heat, these modern installations feature multiple layers of insulation and reinforced edges that work in harmony to maintain your home’s warmth.

The design includes high-performance weather seals along the entire frame and a specially engineered threshold that works effectively to stop heat from escaping at ground level. When you close your composite door, the advanced locking mechanism draws it snugly into the frame, creating an exceptional seal that keeps warm air in and cold air out.

This superior design has been proven through independent testing to retain up to 40% more heat than standard wooden doors, resulting in noticeable improvements to both your comfort and energy bills throughout the year.

Door Maintenance

Keeping your doors in good condition doesn’t need to be complicated, but regular attention makes a significant difference to their performance and longevity. A simple maintenance routine should start with annual checks of all rubber seals and weather stripping, as these components play a vital role in maintaining your door’s energy efficiency.

Every six months, take time to clean the tracks and hinges, removing any built-up dirt or debris that could prevent the door from sealing properly. Pay particular attention to how your door closes and operates, as changes in its movement often signal the need for minor adjustments that can prevent bigger issues from developing.

During the colder months, focus extra attention on the bottom seal of your door, as this area faces the harshest conditions and most frequent use. If you notice increasing draughts or cold spots around your doors, don’t wait for the problem to worsen – a professional inspection can identify and resolve issues quickly.

Quick Fixes for a Warmer Home

Stop Draughts

You can improve your home’s warmth without major expenses. Draught-proofing makes an immediate difference to room temperature. You can also install brush strips at the bottom of doors and use foam strips around windows to block cold air entry points. These simple improvements will make your rooms noticeably warmer.

Secondary Glazing Options

If you can’t replace your windows due to building restrictions or budget constraints, secondary glazing is an effective alternative. It involves installing additional glass panels inside your existing windows. It costs less than full replacement windows and reduces heat loss by up to 65%. This option works particularly well in older properties where original windows must be preserved.

New windows and doors are a long-term investment but the savings on heating bills mean you’ll recover the initial costs within 5-7 years. Your house value could also increase by up to 10% since energy-efficient homes are more attractive to buyers because of their lower running costs.

Common Questions

How much money will I save with new windows?

 You can save between £95 and £175 each year on heating bills, depending on your current windows.

Is triple glazing worth the extra cost? 

Double glazing is sufficient for most homes. Consider triple glazing if you live in a very cold area or near a noisy road.

How long do quality windows last?

 Quality windows typically last 20-25 years with regular maintenance.

Can I get new windows if I live in a listed building? 

Listed buildings require special permissions. Secondary glazing is usually permitted and effectively reduces heat loss while preserving original windows.

When’s the best time to install new windows?

 Installation can happen year-round, but spring and summer provide the best conditions.
