How Servicing Your Windows Can Save You Up to 20% on Heating Bills

When winter arrives, many homeowners notice the cold creeping in, even with the heating turned up.

What most people don’t realise is that draughty or poorly sealed windows could be responsible for up to 20% of heat loss in the average UK home.

The good news……. You don’t need to replace all your windows to fix the problem.

A simple window service can restore efficiency, improve comfort, and cut your heating bills significantly.

🔍 Why Window Servicing Matters

Over time, even the best-fitted windows suffer from wear and tear.

Seals harden, hinges loosen, and frames shift slightly, allowing cold air in and warm air out.

Common signs your windows need servicing include:

•⁠ ⁠Cold draughts or rattling frames

•⁠ ⁠Condensation between glass panes

•⁠ ⁠Handles or locks that stick

•⁠ ⁠Higher energy bills during winter

If any of these sound familiar, it’s time to schedule a professional window service before the cold sets in.

🧰 What’s Included in a Professional Window Service

A qualified window fitter will carefully inspect and maintain each unit to make sure it’s performing at its best. Typical tasks include:

1.⁠ ⁠Seal inspection – Old or perished rubber seals are investigated and possibly replaced to stop draughts.

2.⁠ ⁠Hinge and mechanism adjustment – Ensures the window closes tightly and locks correctly.

3.⁠ ⁠Re-caulking and weatherproofing – External joints reviewed and if needed sealed to prevent water or cold air ingress.

4.⁠ ⁠Glass and frame check – Identifies misted double-glazing or warped frames that reduce insulation.

This full window maintenance service brings your existing windows back to optimal condition — without the cost of full replacements.

💰 How Servicing Windows Can Reduce Heating Bills

According to the Energy Saving Trust, around 20% of a home’s heat is lost through windows and doors.

When seals fail or hinges misalign, that figure can climb even higher — meaning your boiler or heat pump works overtime.

By investing in regular window maintenance, homeowners can:

•⁠ ⁠Cut energy use and lower heating bills by up to 20%

•⁠ ⁠Stay warmer for longer, without relying on higher thermostat settings

•⁠ ⁠Reduce carbon emissions, making your home more environmentally friendly

It’s one of the most cost-effective energy-saving home improvements you can make.

🏠 Additional Benefits of Regular Window Maintenance

Servicing your windows doesn’t just improve efficiency — it also:

•⁠ ⁠Prevents condensation and mould by stopping cold air leaks

•⁠ ⁠Extends the lifespan of your windows

•⁠ ⁠Keeps locks and handles secure for better home safety

•⁠ ⁠Reduces outside noise, creating a quieter indoor space

Regular servicing keeps your windows looking and performing like new — saving money long-term.

🌦️ The Best Time to Book Window Servicing
