How to make your house as energy-efficient as possible

It’s no secret that an energy-efficient house makes for a low-cost home to run, which is why you probably want to ensure that your house is as energy efficient as possible. At Crown Commercial, we have a wealth of experience in all-things energy efficiency, so we’d like to share a few of our top tips with you.

How much could being energy efficient save you?


Energy efficiency involves managing and limiting energy consumption. And, as you pay for your energy, a reduction in use will translate into financial savings for you and your family.


There is no set amount per month that we can guarantee you’ll save on household bills by becoming more energy efficient. However, OVO Energy claims that it is possible for the average UK homeowner to save £405 per year by taking energy-saving measures like insulating the loft, turning off the lights and other appliances when not in use, and turning down the thermostat by one to two degrees.

One of the biggest reasons homeowners don’t take the best steps towards improving their home’s efficiency is the cost. Double-glazed windows and doors are the best way to increase your energy efficiency, but they can force you to dip into your savings pot. This being said, if you can afford to make the initial investment, it will pay for itself. If your windows or external doors need upgrading, you will eventually cover the cost of the new installation through the monthly savings on your energy bills.

Insulate your roof

Ensuring your roof is properly insulated can do wonders for your energy efficiency. An astounding 25% of heat in an uninsulated house is lost through the roof, but people often leave it years before they take action. If cost is the barrier, it shouldn’t be (if you can afford the upfront amount). Though roof or loft insulation can cost you around £300, you’re predicted to save £750 on your energy bills over five years because of this change alone, so you will see a good return on your investment.

Get a new boiler

How old is your boiler? Is it time for a replacement? If you know that your boiler needs an upgrade but you’ve been avoiding the hassle and cost of getting a new one, perhaps this is the nudge you need. Likewise, if you have no idea about the condition of your boiler, now would be an excellent time to give it a check over. 

Your heating accounts for 55% of your energy bills – more than all of your other appliances added together. This means a high performing boiler can make a huge difference to your home’s energy efficiency and your household bills. If you have an old gas boiler, a simple switch to a new A-rated condensing one could save you over £200 per year – something to consider!

Draught-proof your windows

Draughts are incredibly common, especially in houses with older windows, but the effect they have on the temperature of your home can be great. You might need to think about replacing your windows if any of these are true for you:

  • Your windows are hard to close
  • You’ve had your windows for over 20 years
  • The inner window pane is noticeably cold to the touch
  • There is condensation between the panes of glass
  • There are signs of degradation on the window frame
  • You can feel draughts coming through your windows 

Ensure your new ones are double glazed for excellent efficiency (though this usually comes as standard). If you’re not sure how old your windows are, those installed after 2002 should have come with a FENSA certificate displaying their age.

If you can’t get new windows just right now or are looking for some immediate relief, you might also want to take some DIY steps to draught-proof your windows such as using compression seals, silicone-based sealants, brush strips, or low-friction seals.

Insulate your walls

Insulating your walls is another effective strategy to improve the energy efficiency of your home. Solid wall insulation will have a greater impact on your savings than cavity wall insulation (which can still save you over £160 per year), as solid walls let much more heat escape. Though there are high upfront costs (£7000 – £13,000), you could save £260 a year with solid wall insulation – not to mention all that carbon!

If you’re concerned about finances, you might be able to get some help from the Green Homes Grant Scheme – it’s worth taking a look.

Hang thick curtains

If you thought curtains were only useful for blocking out light, then think again. Hang thick curtains over your older windows (or buy linings for your existing ones) to prevent the cold airflow entering your home from the outside. While you might have to accept that your home will be a little less bright, if draughts are a serious issue in your home then this might be a worthwhile trade-off.

Just make sure you remember to open your curtains during the day to let the sun shine in and don’t let them hang over your radiators (as this will prevent warmth from filling the room).

Watch your energy consumption

If you’re reading this article on energy efficiency, chances are you’re already concerned about and are keeping track of your energy consumption. Still, there are always little things we can improve on. Remember to keep up good energy-saving habits like turning off the lights, bleeding the radiators, and investing in efficient appliances. These small actions can translate into big savings so aren’t to be overlooked.

There’s plenty of ways that you can make your home more energy efficient and as doing so will save you money and reduce your environmental impact. There’s no excuse not to take the first step in improving your home today. If you’d like some expert guidance, give us a call or visit us at our Exeter showroom.
