New homes are designed with energy-saving technologies in mind — but many older properties are left behind, wasting energy and money every day.
We’ve created a helpful video to demonstrate exactly where energy escapes from your home during winter. It’s not just draughts — it’s heating you’ve already paid for, leaking straight out.
In summer, the problem reverses. Hot air pushes in, warming your carefully cooled space and forcing your systems to work harder — and cost more.


Save money. Save the planet.
Minimising heat loss and controlling indoor temperature makes your home more energy-efficient — reducing bills and environmental impact.
Upgrading to A-Rated Windows and energy-efficient Doors helps:
• Keep warm air in during winter
• Keep hot air out in summer
• Reduce energy bills
• Block unwanted noise
• Lower your carbon footprint
Less energy wasted. Less money spent. A smarter, greener home.
“I was absolutely delighted with the work that SRN did for me. Eight windows and a door fitted — they arrived when they said they would and left my house and garden spotless. I’d recommend SRN to anyone.”
