How Coventry Homeowners Can Slash Their Energy Bills This Winter

As energy prices continue to be a concern for households across the UK, homeowners in Coventry are increasingly looking for effective ways to reduce their heating costs. With its mix of historic and modern properties, Coventry presents unique challenges and opportunities for improving energy efficiency. At Rockwarm, we have been serving the Coventry community for decades, and we want to share our expert advice on how you can make your home more energy-efficient and save money.

Why Insulation is Key for Coventry Homes

Many homes in Coventry, particularly the charming older properties, were built without modern insulation standards in mind. This often means they have solid walls, which can lose twice as much heat as uninsulated cavity walls. The result? Higher heating bills and a less comfortable home.

By investing in proper insulation, you can create a thermal barrier that keeps the heat in during the winter and out during the summer. This is the single most effective step you can take to reduce your energy consumption.

Insulation Options for Your Coventry Property

Depending on the age and construction of your home, you have several insulation options to consider:

1. External Wall Insulation (EWI)

This is the gold standard for solid-walled properties. By wrapping your home in an insulating layer, you can dramatically reduce heat loss. It also comes with the added benefit of refreshing your home’s exterior.

  • Best for: Pre-1920s homes with solid brick walls.
  • Potential Savings: Up to £400 per year on your heating bills.

2. Cavity Wall Insulation

If your home was built between the 1920s and 1990s, it likely has a cavity between the inner and outer walls. Filling this cavity with insulation is a quick and cost-effective way to improve your home’s energy efficiency.

  • Best for: Post-1920s homes with uninsulated cavity walls.
  • Potential Savings: Up to £280 per year.

3. Loft Insulation

Did you know that an uninsulated home can lose up to 25% of its heat through the roof? Loft insulation is one of the easiest and most effective ways to save energy. If your loft insulation is less than 270mm thick, you could benefit from a top-up.

  • Best for: Any home with an accessible loft.
  • Potential Savings: Up to £250 per year.
