Worrying about your Electric?

Do you think your electric bills are too high, or there are things you don’t understand on your bill? Maybe you are unsure what tariff to be on.

We are here to help.  Just send us your invoice and we can review it, clarify what things mean and guide you to any possible saving.

Once we have reviewed your bill, you will receive a personal report showing what you could save if you switched to the best deal available.

We are independent agents, 100% working on your behalf.

We do not charge for our services.

Do you need to Change your contracted kW?

Maybe you think you are contracting too much and can make a saving by reducing the contracted kilowattage; or your power keeps tripping out due to an overload and you need to increase kilowattage!

You lifestyle may have changed, or the previous property owners were high energy users.  Then we can reduce your contracted kW for you.  Your electric distributor will charge around €9 (+IVA) to lower your contracted kW.  You could save about €40/kW/year (+IVA), but don’t lower it too much as an increase in kilowattage is pricey.

If you need to increase your contracted kilowattage, this costs around €37/kW increase + €9 (+IVA).

We are available to discuss your needs and recommend the kW.  We will then complete the necessary paperwork for the required changes. 

Save by Changing to another Tariff

There are many different tariffs available, each offering benefits depending on your lifestyle.

  • Day/Night Tariffs

  • Solar Virtual Battery

  • Fixed Rate

  • Indexed

We can guide you to the best tariff that fits your lifestyle, enabling you to make the most savings.

Solar Energy

A typical solar system can save between 80% and 100% on your energy bills, depending on system size and placement.

How do you Save?

Without doubt a solar installation will save you money from day one, but at a cost; so you need to ensure you are having the correct size installation for your property/lifestyle.

You will save on your day to day usage, as most of the energy you will use will be from your own production.

You will also be sending excess energy back to your electricity provider, which should be paid back to you as a credit on your bill.

There are many solar tariffs available; LUZ123 can you guide you to the best one where you benefit the most.

Free No Obligation Quote

Contact LUZ123 for a free no obligation quote for a solar installation that meets your needs.

Each installation is very personal, we need to review your current and planned future usage along with available roof space.  We work with you to reduce your bill to Zero.

There is only so much saving you can make with a solar installation; if you install big your electricity company will benefit more than you. With the correct installation payback can be less than 4 years.
