How it works
Three steps is all it takes — and you never have to call your current supplier or touch a form.
1.
Send us your bill
Upload any recent electricity bill using the form above. That’s it — we take it from there.
2.
We compare 20+ suppliers and send you a personal report
We review your current tariff, your contracted kW, and your usage pattern. If we spot any unusual charges, we’ll flag those too. You’ll receive a clear report showing exactly what you could save and which supplier we recommend.
3.
Switch with a single click — we handle the paperwork
When you’re ready, we prepare the new contract. In most cases it’s signed with a single click. No meter change, no interruption to your supply, no contact needed with your old supplier.
Why clients stay with us year after year
Unlike price comparison websites, we don’t just find you a deal once and disappear. We keep watching.
- We switch you every year, automatically
All suppliers raise their prices after the first year. We monitor your contract and move you to the best deal before it happens.
- Real people, real support
Something wrong with your bill? Supplier problem? Our team deals with it for you — in English, from our office in Jávea.
- Completely free - we're paid by the supplier
Like an insurance broker, we’re paid a commission by the supplier you switch to. You pay nothing, and we never recommend a supplier just for the commission.
- 10 years, physical offices, a real track record
We’ve been doing this since 2015. We have a registered office, a real team, and over 1,000 clients whose bills we look after.
Beware of fly-by-night switching agents
Since the energy market opened up in Spain, some agents have switched clients purely to collect commissions — then left them to deal with billing errors and contract problems alone. LUZ123 is different: we’ve been trading for 10 years, we have a physical office you can walk into, and we’re here to help if anything goes wrong — before, during and after your switch.
We find the right tariff for your lifestyle
There’s no single best deal — it depends on when you use electricity, whether you have solar, and how much you use. We match you to the right one.
Is your contracted kW right for your home?
Too much contracted kW and you’re paying a standing charge you don’t need — every kW costs around €40/year. Too little and your power keeps tripping. We check this as part of every review and can arrange changes for you.
Changing the Name on the Contract
Have you just bought or sold your property and need to change name on the property electricity contract?
No problem, give us the new details and supporting documents, we will then prepare the new contract for you.
