How Replacing Your
Windows And Doors Protects Your Wallet This Winter
Ofgem has confirmed the energy price cap is jumping by 13% (roughly £221 a year)
on July 1st, bringing a typical bill up to £1,862. Even worse, analysts like Cornwall
Insight are already warning that October bills will climb even higher as winter
approaches. Homeowners are you feeling highly cost-conscious? You may want to
think about acting now before that deadline hits. While we are going into Summer,
the choices you make now will dictate what your Winter bills will look like.
While changing energy suppliers might offer minor relief, the most effective way to
lower your bills permanently is to stop wasting the energy you’re already paying for.
That starts with your windows and doors.
The Hidden Cost of Outdated Glazing and Drafty Doors
Many homeowners don’t realise that windows and doors are responsible for up to
25% to 30% of a home’s total heat loss. If your double glazing is old (typically over
15 years old), or if you’ve noticed a few telltale signs of failure, your home is actively
leaking money.
Signs Your Windows and Doors Are Costing You Money
The “Letterbox Breeze”: If you can feel a draft through your letterbox,
around the edges of your front door, or near window seals, expensive warm
air is constantly escaping.
Condensation Between Glazing Panes: This means the gas seal has failed.
Your window or glass door panel is no longer insulating your home.
Gaps in the Frame: Over time, heavy doors can drop or warp on their hinges,
creating microscopic gaps that act like an open vent for cold air.
Cold Frames: Touch your window frames on a chilly morning. If they feel ice-
cold, heat is conducting straight through them to the outside world.
How Modern Windows and Doors Protect Your Wallet
Upgrading your home’s exterior isn’t just a cosmetic improvement – it is a great
financial strategy against rising energy caps. Here is how modern window and door
engineering works together to lock heat inside your home:
A-Rated Energy Efficient Windows
Modern windows are rated on an efficiency scale from A++ down to E. Installing A-
rated windows ensures that solar heat from the sun is naturally let in, while internal
heat from your radiators is reflected back into the room. This drastically reduces the
amount of time your heating needs to be switched on.
Ultra-Insulating Solid Core Doors
While standard composite doors use cheaper foam fillings, we install premium
Endurance doors featuring a 48mm solid timber core. Built from 17 layers of
engineered timber, they are 10% thicker and 40% heavier than standard doors. That
solid “clunk” when you close it doesn’t just mean elite security; it provides a massive
thermal barrier that locks heat inside. Plus, with an integrated moisture barrier to
prevent warping and perfectly foiled frames for an airtight fit, it stops winter drafts
completely without compromising on style.
Advanced Weather Seals and Multi-Point Locking
A door is only as warm as its seal. Today’s doors feature continuous, dual-seal
gaskets that compress tightly when shut. Combined with secure multi-point locking
systems, the door is pulled flush against the frame at multiple points, eliminating
whistles and cold spots.
Smart Low-E Glass and Argon Insulation
Whether it’s a window or a large glass panel in your back door, high-performance
glazing utilises Low-Emissivity (Low-E) invisible coatings and Argon gas fillings. The
Argon gas slows down heat transfer between the panes, while the Low-E coating
reflects your indoor heating back into the room during winter.
Thermal Breaks in Frames
Whether you choose low-maintenance uPVC or sleek, modern aluminium, today’s
frames are built with multi-chambered profiles or internal “thermal breaks.” These act
as insulation barriers inside the frame itself, stopping the cold bridging process
entirely.
Act in June to Beat the Autumn Rush
The best time to fix a leaky roof is when the sun is shining and the same for your
windows and doors – secure your home is before the cold weather hits. Upgrading
your windows and doors in June offers several distinct advantages:
Warm Installation Weather: Replacing doors and windows requires opening
up the house. Doing it in June means you won’t have freezing winds blowing
through your living room during the installation.
Beat the Autumn Panic: September and October are peak seasons for
window and door companies as homeowners panic before winter. Booking in
June ensures shorter lead times.
Immediate Energy Peace of Mind: You can head into the July 1st price cap
rise knowing your home is fully optimised to retain heat.
