If you pay your own energy bills, or contribute to them, you know the struggle of winter inflation. While you can wrap up under the covers with a hot beverage and comfort food, it doesn’t provide the same warmth your heater does. But the cost of constant heating amounts, so what can you do to prevent this? 
Want to know how to keep heat in your house? Read on to learn how to save on energy bills and check for poorly insulated windows. 

How Does Poor Window Insulation Cost Money? 

Your heater works hard to supply warmth to the entire room, but heat loss means it can’t rest. At least 18% of heat escapes through gaps in windows and doors. The space is bound to get colder once your heater is off, and you’ll soon find yourself doing whatever possible to stay warm. 
Boiling the kettle? Cooking a hot meal? Using an electric blanket? Turning back on the heating? This extra usage will drive up your energy costs. But thermal secondary glazing will give your heater a break with additional insulation. 

How Much Can I Save? 

In comparison to a single-glazed and semi-detached gas-heated home, installing A rated windows could save you £155 per year and 375kg of carbon dioxide. Not only does this ensure an energy-efficient and cost-effective winter, but a safer one too. 
While the cost of secondary glazing varies on the supplier, quality, and materials, the average cost is £1,000 - £2,000 per window, excluding VAT and installation fees. 

How Can I Check My Window Insulation? 

Ideally, you should already know the energy rating of your windows, but it’s easy to check if you don’t. There should be a label on or in your window, or you can check the invoice if you have it. If not, ask a: 
Household member 
Former tenant or owner 
Landlord or estate agent 
Council or housing association 
Residential assistant 
If not it’s not possible to check, you can physically check your room instead for: 
Cold spots 
Peeling paint 

What Types of Windows Have the Best Insulation? 

The best insulating windows for winter depends on your budget and the size of your property. Both double and secondary glazing offer better thermal insulation than single-glazed windows. However, double glazing requires planning permission because the original window needs to be removed, which changes the architectural integrity of the build. 
Whereas heritage sites benefit from secondary glazing, which doesn’t require planning permission. This sits alongside the original window, providing better insulation and soundproofing. 
Heat-loss windows don’t just depend on the glass type, but on the frame too. Similarly, vinyl, wood, and fibreglass frames all provide better insulation than metal frames.
