Why Upgrade Your Glazing?
UK households are facing another sharp increase in energy costs, with Ofgem announcing that the energy price cap will rise by yet another 4% from October 2026. This is one of the largest summer increases in recent years and is expected to add around £60 per year to the average household energy bill.
This increase is a result of higher wholesale gas prices, caused by the ongoing conflict in the Middle East, and with no end in sight, this is particularly concerning for homeowners already feeling the pressure of the cost of living crisis.
At SEHBAC, we believe there has never been a more important time to make your home as energy efficient as possible.
Why Are Energy Bills Rising?
The latest increase has been driven largely by higher wholesale gas prices and instability in global energy markets. Ofgem confirmed the average annual household bill will rise to £1,723 from 1st October.
For homeowners, this means one thing: reducing heat loss is no longer just a “nice to have” – it’s essential!
Your Windows Could Be Costing You Money
You cannot control wholesale energy prices, but you can take steps to reduce the amount of heat your home loses.
Windows are one part of that picture. Older glazing, worn seals and gaps around frames can allow warmth to escape, making rooms harder to keep comfortable. If you notice draughts or cold spots near your windows, it may be time to assess their condition.
Improving insulation, addressing draughts and upgrading inefficient windows can all help your home retain more of the heat you pay for.
Triple Glazing Could Save You Around £200 Per Year
According to the Federation of Master Builders, upgrading to triple glazing could save homeowners up to £200 annually on energy bills.
With the latest energy price cap increase also expected to cost households around £200 extra per year, upgrading your windows could effectively offset the rise completely.
That means improved comfort, lower energy usage, and long-term savings all at the same time.
Why Triple Glazing – Is Worth It?
Triple glazing provides an additional pane of glass and insulating layer compared to standard double glazing, helping to:
- Keep heat inside your home for longer
- Reduce draughts and cold spots
- Lower energy consumption
- Improve noise reduction
- Increase home comfort all year round
As energy prices continue to fluctuate, improving insulation is one of the smartest investments homeowners can make.
