DIY Energy Saving Hacks: Make Your Home Greener and More Efficient.

When it comes to saving energy and making your home more comfortable, even small changes can go a long way. At Assembly Renewables, we believe that every homeowner can take simple, practical steps to boost efficiency and reduce their environmental impact. Whether you’ve already invested in renewable energy or are just beginning your journey, these DIY projects will help you save money, cut carbon, and enjoy a warmer, more efficient home.

Start with the Basics: Keep the Heat In

Let’s face it—no one likes a draughty home. One of the quickest and most satisfying ways to improve your energy efficiency is by tackling heat loss. Draught-proofing is a great place to begin. You can seal up those pesky gaps around windows and doors with self-adhesive strips or brush seals. Even your letterbox and keyholes can let cold air in, so don’t forget to cover those too.

And if you have a chimney that’s just decorative now, think about using a chimney draught excluder or balloon. It stops warm air escaping and cold air creeping in, all while being easy to fit and remove when needed.

Make the Most of Your Radiators

Your radiators work hard to heat your home, but did you know a lot of that heat might be lost through the walls? By fitting radiator reflector panels, you can bounce that heat right back into your room where it belongs. It’s a quick and cost-effective job that pays off in extra warmth.

Another overlooked tip—bleeding your radiators. If they feel cold at the top and warm at the bottom, they probably have trapped air. A radiator key and five minutes of your time can make them work more efficiently, keeping you cosy and using less energy.

Light Up, The Smarter Way

Lighting is one of the simplest areas to tackle. Swapping out old halogen or incandescent bulbs for LEDs can save you up to 80% on lighting costs. LEDs last much longer too, so you won’t be up a ladder every few months replacing bulbs.

Go Beyond Heating: Save on Water Too

Hot water is another big part of your energy use, so small tweaks here can also help. Adding a jacket to your hot water tank, if you have one, helps keep the heat in, so your boiler doesn’t need to work as hard. It’s a classic DIY job that pays for itself in no time.

You can also fit tap aerators in your kitchen and bathroom. They reduce the flow of water without affecting pressure, so you use less hot water with every wash or rinse. Less water used = less energy needed to heat it.

Take It Outside: Make Use of Nature

Energy saving isn’t just about indoors. Setting up a water butt to collect rainwater is a brilliant way to reduce your mains water use, especially for gardens. It’s eco-friendly, and if you love your plants, they’ll thank you too—rainwater is often better for them than treated tap water.

Bringing It All Together

These DIY projects are just the start of what’s possible when it comes to energy efficiency. Small changes, like sealing draughts or fitting LED bulbs, build up to real savings over time. They make your home more comfortable, reduce your environmental impact, and prepare you for even bigger steps—like upgrading to a heat pump or solar PV system.
