Save on energy bills in winter in West Yorkshire: A guide to windows and doors

When the temperatures fall, homeowners across Leeds and West Yorkshire face the same challenge: how to stay warm without overspending on heating. The good news is there are practical ways to save on energy bills in winter in West Yorkshire, from quick, low-cost fixes to longer-term upgrades like new windows and doors.

At Leeds Glass, we’ve been helping local families improve their homes for over 40 years. In this guide, we explain the most common ways homes lose heat, share practical quick wins you can try straight away and show how the right windows and doors can make a real difference to your comfort and bills this winter.

Where do homes lose heat in winter?

Before looking at ways to cut costs, it’s helpful to understand where heat is most often lost in the home. Some areas are obvious, while others might be overlooked. Knowing where the weak spots are makes it easier to know which improvements will help you get the most benefits.

  • • Windows: More than 20% of a home’s heat can escape through poorly insulated windows, according to research from Glass and Glazing Federation. Older single glazing or outdated double glazing are common culprits, but modern glazing is designed to hold warmth in much more effectively.
  • • Doors: Gaps around frames, letterboxes and doors made with older materials can let the cold creep in, so you end up turning up the heating to compensate. Adding draught-proofing or upgrading to a more insulated door will help.
  • • Loft: Heat rises, so without proper loft insulation, it goes straight out of the roof. Topping up loft insulation is one of the simplest improvements you can make.
  • • Walls: A lot of older homes, like Victorian terraces, are built with solid brick walls that allow heat to escape faster. Newer homes are built with ‘cavity walls’ – two layers of brick with an insulating gap in between, which helps keep heat inside.
  • • Floors: In older houses with timber floors, gaps between and underneath the floorboards can let in cold air, making the room harder to heat. Sealing and insulating beneath the floor reduces wasted energy and makes the room warmer.
  • • Draught points: Small gaps (like those around skirting boards, chimneys or pipework) can add up. They’re often caused by dated fittings and are especially common in Leeds’ Victorian terraces and mid-century semis. Sealing any gaps is a quick and easy way to cut down on draughts.

Quick, low-cost winter fixes you can do now

Before thinking about bigger upgrades, it’s worth looking at the small changes that can make your home feel warmer straight away. These fixes are usually inexpensive, simple to put into place and a great starting point before investing in new windows or doors.

Stop draughts around doors

Simple fixes like adding draught-proofing strips, brush seals on letterboxes or a cover for the keyhole can make a big difference. A basic draught excluder along the bottom of the door can stop a lot of cold air getting in too.

Keep the heat in at windows

Closing heavy curtains or fitting thermal blinds gives your windows an extra layer against the cold. You can also use window film or seal small gaps around frames to cut down on heat loss.

Get the most from your radiators 

There are a few quick jobs that make sure your radiators are giving out as much heat as possible.

• Use reflector panels: these sit behind the radiator and push heat back into the room instead of letting it escape through the wall.

• Bleed your radiators: radiators work by filling with hot water. If air gets trapped inside, water can’t circulate properly and the radiator won’t heat evenly. Bleeding them from time to time removes the air and keeps them working at their best.

• Fit smart valves: Smart radiator valves let you set different temperatures in different rooms, so you’re only paying to heat the spaces you actually use.

Ventilate without wasting heat

Fresh air helps combat condensation and damp, but you don’t need to keep your windows open all day to get enough ventilation. Trickle vents in modern windows allow a steady flow of ventilation even while windows are closed, keeping air moving without letting all the heat escape.

For older windows, a quick blast of fresh air from opening windows for a few minutes is usually enough to refresh a room without losing too much warmth.

Windows: what makes a difference in winter comfort and bills

Older single glazing or early double glazing often doesn’t keep the heat in as well as it should. That can leave rooms colder, increase condensation and push up heating costs. Modern energy-efficient windows are built to stop heat escaping, making homes more comfortable and bringing bills down.

Today’s double and triple-glazing includes several design features that make a big difference to insulation and comfort. Energy ratings and U-values show how well a window performs, while other details in the frame and glass itself help keep the cold out and the warmth in.

Key things to look for include:

  • • Energy ratings A to A+: A quick way to compare overall performance
  • • Low U-values: The lower the number, the better the insulation
  • • Argon-filled glazing: Gas between panes slows down heat loss
  • • Warm-edge spacers: Reduce heat transfer around the edge of the glass
  • • Low-e coatings: Reflect heat back into your home instead of letting it escape

For period or conservation properties, secondary glazing is often the most practical option. It improves insulation without changing the look of original windows, so you can keep the character of the home while still cutting down on heat loss.

Why you might see condensation outside new windows

Don’t worry if you notice condensation forming on the outside pane. It means your windows are doing their job – keeping warmth in so well that the outer surface stays cooler.

Doors: often overlooked but crucial in winter

People often think about windows first when it comes to heat loss, but doors can make a difference in how warm your home feels. A badly fitted or outdated front or back door can let cold air straight in and waste heat you’ve already paid for.

Here are some of the key things to look out for when it comes to choosing doors for comfort in winter:

  • • Composite vs uPVC: Both types perform well, but composite doors generally offer the best thermal performance thanks to their insulated cores. Modern uPVC doors also provide insulation through multi-chambered frames. Both are low-maintenance options that improve both insulation and security in your home.
  • • Seals and fittings: Good seals and high-quality multi-point locking systems help stop draughts around the edges of your door.
  • • Surrounding glass: If your door has glass panels alongside or above it (sidelights or transoms), upgrading them to modern, energy-efficient glazing can often make a noticeable difference.

Cost vs savings: what’s realistic in West Yorkshire?

Upgrading your windows and doors is an investment, but it pays off over time. The exact savings will depend on the age of your current glazing, the size of your property and how you use your heating, but many customers notice the difference straight away.

These are some of the most common upgrades that strike the balance between upfront cost and long-term savings:

  • • Replacing old double glazing: If your windows are 15-20 years old, chances are they’re not doing the job they once did. Modern glazing keeps the warmth in far better, and most people notice the difference in comfort and bills as soon as the first winter rolls around.
  • • Upgrading from single glazing: Moving from single to double or triple glazing is one of the biggest leaps you can make. Rooms feel warmer, with fewer draughts and cold spots, and condensation is much less of a problem.
  • • Swapping out old timber doors: A draughty timber door can undo all your efforts to keep the house warm. Switching to a composite or modern uPVC door seals in the heat more effectively, and improves security for better peace of mind.

It’s not just about lowering your energy bills. Better glazing and doors mean a home that’s quieter and warmer – so the benefits are felt every day, not just on your heating statement.

What’s right for different West Yorkshire homes

Heat loss can come from hidden weak spots around the home. What’s behind it often depends on the property itself, whether it’s a terrace, a semi or something more modern.

Victorian terraces

We often find these homes have solid walls, older glazing and draughts around original fittings. Adding secondary glazing or replacing windows makes a noticeable difference to warmth and comfort.

1930s semis

These are common around Leeds and Bradford. Many still have early double glazing or dated doors, so upgrades here usually improve both energy performance and security.

Post-war estates

Mid-century semis and detached houses often still have timber doors or early double glazing. Modern replacements cut down heat loss and give better protection against the weather.

Rural properties

Homes in more exposed spots face stronger winds and colder conditions. High-performance glazing and well-sealed doors help keep them warm and protected.

Because Leeds Glass has worked on homes across West Yorkshire for over four decades, we understand the challenges each type of property brings and can recommend the most effective upgrades.
