You know, 2020 has been difficult enough without receiving a letter from our water company informing me our bill is going up. Again.

This made me have a good, hard look at the rest of our bills and to question again the ways to save energy and water.

Energy is expensive and I’m informed enough to know that we can only expect it to become even more expensive. Still, we did manage to reduce energy and utility bills once and I really want to do it again.

Using The Money Principle ERR strategy for money management I developed a checklist to save energy and to reduce our utility bills. You may wish to use the list as well and save yourself a ton of money you otherwise waster. It is not only your wallet that will thank you but also you will be contributing, albeit in a small way, to the effort to look after our environment a bit better.

Just to remind you that the ERR strategy for money management is about three things:

  • Eliminate (waste);
  • Replace (change the way in which you do things); and
  • Reduce (consumption).

Here is what actions you must to take, I believe, under each of these to keep your energy and utility bills under control.

Eliminate: 7 easy ways to save energy at home by eliminating waste

Here are seven easy and straight forward ways to eliminate waste and save energy at home.

Some of these you can implement immediately, others may need to wait; some are cheap to put in action, others not so much.

All are very much worth doing: by eliminating waste of energy you can save hundreds per year. And it feels so great!

#1. Pull the plug

Okay; how many of your electrical appliances are left on standby? My guess will be ‘many’. And this is waste of energy you really don’t need – most appliances will be perfectly fine if you pull the plug (watch for some TVs and recording devices because these may lose their memory if plugged off). Word on the street is that, depending on how many devices you us, you can save between £35 and £50 per year by simply un-plugging. Doesn’t sound much but this is: one week of food, couple of pairs of trousers, a pair of shoes or a nice little chip off your debt (or contribution to your ISA). So, think again.

#2. Put out lights

My Dad used to drive me mad when I was little by sending me back to put out the lights. I thought he is un-necessary stingy. Now I do the same (except when I forget the lights on which annoys John terribly). Leaving lights on when there is no one who needs light is a waste of the worst kind. So, put the lights off; and teach your kids to do it as well.

#3. Get yourself some draught excluders

I know, I know. These look very silly and you can trip in them. They help keep the heat in, though. Which is kind of important during the winter – after all, why would you willingly choose to heat the universe; and pay for it. While you are at it, you may wish to get some heavy curtains as well.

#4. Carpet is better than wood

This is the bane of our marriage: I like wooden floors and John wants to stick with carpets. There is a mixture of flooring in our house but I’ll have to say that carpets do keep the house warmer.

#5. Get some more insulation

I’ve come to believe that insulation is a bit like shoes: one can never have enough of it. We have cavity wall insulation (needs renewing), loft insulation…all kinds of insulation. It makes a very big difference and it not only keeps the heat in: in summer it keeps it out better as well.

#6. Double glazing

Yes, it is true: in the 21st century, some houses in the UK still don’t have double glazing. When it comes to eliminating waste and saving on energy, this is essential.

#7. Check for drips

Sounds trivial, I know. But dripping water can really lead to very large waste of both water and energy (to heat and move it around the house). And it is annoying!

Replace: 7 easy changes to save energy and slash your bills

You can save on energy a lot by eliminating waste; you can save even more – and more sustainably – if you change the way you do things when it comes to energy use.

Here are seven changes that can lead to large energy saving gains:

#1. Change your light bulbs

Yes, get yourself some energy saving bulbs. They don’t come cheap but they also pay for themselves from savings within several months. This doesn’t mean that you should start leaving the lights on but it won’t be so bad if you occasionally forget them on.

#2. Buy new appliances

New white goods are generally much more energy efficient that the ones made 5-10 years ago. The interesting question is, what you do if a very old appliance that sucks energy like a thirsty man on a bottle of cold beer is still working. In such cases, I do the maths: how long would it take for the more energy efficient and new appliance to pay for itself? This helps decide what to do.

#3. Get/use a dishwasher

It is only natural to believe that washing by hand is more energy efficient than using a dishwasher. As most natural beliefs, this is wrong. A full dishwasher load uses 4 gallons of hot water per cycle (and this washes eight full place settings). An average faucet flows at 2 gallons per minute. This means that you can hand wash more economically than a dishwasher if you can wash eight place setting in two minutes. You see?

#4. Change your energy supplier

We’ve been doing this one with some regularity over the last five years or so. It certainly pays off to be an energy shopper – getting cheaper energy complements nicely the other actions you can take to save on energy. Even only moving from a variable tariff to fixed one can save you up to £250 per year. There are three steps to efficient energy shopping. First, you have to take stock of your energy bills; then you have to shop around; and lastly, you have to take control and act on your research.

#5. Install solar panels

Installing solar panels is an important change when you wish to save on energy. This is something that needs an initial investment, though. If you’d like to know more based on our experience with installing solar panels you can read it here. What I want to mention is that out solar panel generate annually over £700 worth of electricity (about 12% ROI) in ‘sunny’ Manchester.

#6. Change your heating controls

We’ll need to do this one – our heating controls are so ancient that we often find the heating on when it shouldn’t be. Sometimes, I’m freezing because the heating has not come on. Now there are advanced heating control systems that allow you to time your heating precisely, heat different parts of the house at different times, etc. Certainly worth a second thought.

#7. Change your shower head

I always suspected that our drench shower is more efficient than the movable head. It turns out I’m right. Look into changing your shower head with a water saving one – this way, you can have a decent shower and save on water and the energy to heat it.

Reduce consumption: 5 things to remember when aiming to reduce your energy consumption (and bills)

You will reduce your energy consumption substantially by implementing all the ways to eliminate waste and change your energy use.

Further, you can think whether you are over-consuming.

For instance, you need to remember the following:

#1. You don’t have to wear only t-shirt in the winter

This sound ridiculous, I know, but there are people who’ll have their thermostat on high and the windows opened because they are too hot. You don’t have to walk around your house in a t-shirt in the winter, you know; just put a jumper on.

#2. Your oven doesn’t have to be heated an hour before the meal is ready to go in

Again, sound funny but even I do this one from time to time. I start preparing the meal and put the over on; trouble is the over takes 7 minute to heat and the meal 25 minutes to prepare. You see what I mean? (A variation on this one is heating a kettle when you need a cup and having the heating on in rooms you don’t use.)

#3. Empty rooms don’t need light

This has really started to annoy me. My son leave all lights on, all the time. (It also makes me realise that I’m becoming like my father at his most annoying; still, he had a good point it seems.)

#4. Showers are to get clean

Showers are to get clean and this takes approximately 6 minutes (sorry to sound like Jack Reacher here but this is my limit; I’ve times it). Both my husband and my son tend to use the shower for other purposes like to get warm, or to have some pleasant thinking time. This is over consumption.

#5. Double check the water tabs

Yes, we do this one. John and I forget them on; our son at some point couldn’t be bothered. So much so that I had to resort to non-traditional measures (see photo above).


I use this list of ways to save energy regularly to make an inventory of our energy and water use. This certainly helps me keep our energy bills optimal.

Are you curious which ones I’m not really good at?

Here they are:

  • I keep my appliances on standby.
  • I forget (occasionally) the lights on.
  • I need to change the heating controls.
