Britons pay far too much for their energy bill — here's how you can reduce yours significantly.

Are you tired of paying huge amounts on your energy bill every month?

Would you rather spend your money on something else — without having to change your lifestyle? Then you don't need to look any further, because a sharp British mind has developed a solution that significantly reduces your energy consumption and saves you a lot of money.

We had an exclusive opportunity to interview him for Energy News UK after his return from London. In this article you can read how you can legally significantly reduce your electricity costs.

Who is Oliver Harris, the British genius who has developed a method to lower his energy costs?

Oliver Harris is reminiscent of Richard Branson, James Dyson and Sir Tim Berners-Lee. He completed his engineering degree two years earlier than his fellow students and moved to Manchester in 2020 to start his next start-up — a project that would revolutionise the industry.

Later, Oliver Harris teamed up with two other talented British engineers to develop a solar energy system that anyone could install at home for under £130. But they quickly realised that the project was doomed to failure: the price of the electronic components made it financially unsustainable.

Then Oliver Harris had a brilliant idea: why help people produce more energy when you can prevent unnecessary consumption instead? The team developed a device that optimises power consumption so effectively that most households' see their electricity bill drop significantly.

Three months later it was a huge success. First in Manchester, then in Birmingham and finally in London everyone was talking about this 'magical' device that helps thousands of households reduce their electricity consumption — without them having to change their habits.

Why British Gas won't want you to know about this Energy Cost Saving device.

It's EnergyGuard™: a small box that can easily be plugged into any electrical socket. The big advantage is that anyone can use it — whether you live in a flat, house or cottage. All you need is a free electrical socket.

Once plugged in, the device immediately begins to prevent unnecessary energy from flowing through your home's electrical system.

Household appliances often use more energy than necessary — this is due to disruptions in the electricity supply.

EnergyGuard™ minimises these disturbances and therefore logically reduces the amount of wasted electricity. It does not change the meter reading and does not 'steal' any electricity — it simply ensures that energy is used much more efficiently.

How does it work?

Very simple: just like any other electrical appliance, you plug the EnergyGuard™ box into a socket. From that moment on, it immediately starts analysing and optimising your power consumption. The only difference you will notice will be on your electricity bill.

Here are the instructions:

  1. Find a free electrical socket

  2. Plug the EnergyGuard™ device into the power socket

  3. Leave the device connected 24/7 and benefit from a reduction in your energy bill without changing your consumption pattern.

Want to use the device somewhere else? Simply unplug it and plug it into another socket of your choice. It's that simple.

PS: Detailed instructions for use are included with the product.

How much money can you save with EnergyGuard™?

It is difficult to state the exact amount you can save with EnergyGuard™ as each household has different energy consumption and different electrical appliances.

To give you a concrete impression, we asked two users in the UK — each with a very different household — to share their monthly electricity bills from before and after installing the device.

First test: a 55 m² flat (a couple)

Before EnergyGuard™, the average monthly electricity bill was £90.09. After installation, the electricity bill dropped to just £15.83 the following month — a reduction of almost 82%, without changing consumption habits. This corresponds to an annual saving of over £991.78 — a very impressive amount.

Second test: a 145 m² detached house (two parents and three children)

Before EnergyGuard™, the average monthly electricity bill was £245.70. After installation, the bill dropped to just £28.50 the following month — a whopping 91% drop. This translates into annual savings of over £2,620.80, which is a huge relief, especially for families on a tight budget.

One thing is certain: both users told us their bill was lower in the months after installation. How much you save depends on your own consumption, your appliances and your tariff.

One last tip: For flats under 70 m², one EnergyGuard™ unit is sufficient. For larger rooms, multiple units can be used to maximise savings.

Is it dangerous? Is it legal?

As mentioned earlier, the device only optimises the power supply to prevent unnecessary energy consumption. It is not a device that manipulates the meter reading. If it were not legal, the company would not be allowed to market this product at all.

So the device is 100% legal and completely safe. You have every right to buy it. And if for any reason you want to stop using it, just unplug it.

As you might imagine, energy suppliers are not happy about the launch of this product and will do everything they can to avoid hearing about it. However, they cannot legally ban its use — so you can continue to save on your energy bill.

This is what users say after installing EnergyGuard™:

'I am truly amazed at how effective this little device is. I still can't believe it is so unknown — I had never heard of it before my purchase. I have been using EnergyGuard™ for a month now and my electricity bill has already been more than halved compared to last month. Absolutely incredible — thanks to EnergyGuard™ I save almost £38.20 a month and have recouped the investment in less than a month.'

— Emily, 44 years old

'I have a friend who works in the energy industry, so I already knew that electricity and gas companies have high margins — but I never imagined it would be this much. With just one EnergyGuard™ I reduced my electricity bill significantly, and a friend who also bought one saved exactly the same. It's amazing — I'm telling everyone so they can benefit too.'

— Michael, 55 years old

'If I could only recommend one product this year, it would definitely be EnergyGuard™. Within a month, the cost has been recouped through savings, and now that electricity feels cheaper, we actually dare to use more than before — without a guilty conscience.'

— Jessica, 35 years old
