Living in Spain by the Lagom-style: Energy Efficiency Tips | Nordy

Written by Ricardo Londoño | Mar 9, 2026 3:20:36 PM

Moving to Spain from another country brings many changes: the climate, the culture, and daily routines. Knowing how to set up your electricity as an expat will help you plan your consumption and avoid surprises.

You may already be used to energy-efficient habits almost instinctively, but understanding the Spanish electricity system and your tariff options can make a big difference.

Applying the Nordic philosophy of Lagom—“not too little, not too much, just enough”—helps you live comfortably, save money, and be more sustainable from day one.

One of the first steps when you arrive is to check the energy performance certificate (EPC) of your new home. This document gives a clear idea of your expected energy consumption and allows you to plan your electricity use more effectively.

What 'Lagom' Living Means and How It Applies to Energy

The Origins of Lagom

Lagom is a Swedish word meaning “not too little, not too much, just right.” More than a concept, it’s a lifestyle philosophy covering everything from home decor and organization to responsible resource management, including energy.

In Nordic countries, where winters are long and energy resources are limited, efficient consumption is natural. Applying this philosophy to your electricity use in Spain means using exactly what you need—without wasting energy or sacrificing comfort.

From Lifestyle to Your Electricity Bill

Moving to Spain means adapting to a different electricity system: the Mediterranean climate reduces heating needs but increases air conditioning use in summer; daylight hours vary, and electricity tariffs work differently. Adjusting your habits with Lagom in mind helps balance comfort and efficiency, avoiding unnecessary expenses or wasted energy.

First Steps When Moving to Spain

1. Understanding the Spanish Electricity System

Spain’s electricity market is liberalized: you can choose your provider and tariff. There is a regulated market (PVPC) and a free market, each with its own pricing and conditions. Understanding key concepts like contracted power, billing periods, and time-of-use tariffs will help you make informed decisions and avoid surprises on your bill.

2. Why Checking the Energy Performance Certificate Is Essential

Before moving in, request the energy performance certificate. Required in Spain for all homes for sale or rent, this document shows your home’s efficiency and estimated energy consumption. It allows you to anticipate electricity needs, identify potential improvements, and plan your budget more accurately.

What the Energy Performance Certificate Shows and How to Interpret It

The EPC provides detailed information about your home:

 

  • Energy rating: from A (most efficient) to G (least efficient).
  • Primary energy consumption: in kWh/m² per year, useful to estimate electricity needs.
  • CO₂ emissions: to understand the environmental impact of your consumption.
  • Technical characteristics: insulation, windows, heating, and cooling systems.
  • Improvement recommendations: specific measures to optimize efficiency.

How to Obtain or Check the Certificate

If you’re renting, the landlord must provide it. If you’re buying, the seller is legally obliged to deliver it before signing. If it doesn’t exist, you can request it from an authorized certifier. Certificates are valid for 10 years, so recent homes usually already have one.

Using the Certificate to Plan Your Consumption

With this data, you can estimate your electricity needs. For example, an 80 m² home with a D rating and an estimated consumption of 150 kWh/m² per year would need about 12,000 kWh annually. This helps you choose the right power, compare tariffs, and realistically plan your monthly budget.

Remember: energy consumption and your bill depend directly on how you use electricity each month—even during low-activity periods.

Practical Tips to Optimize Your Consumption from Day One

  • Analyze daily habits: adapt your routine to the Spanish lifestyle (later meals and social activities) to shift your consumption pattern. Run high-energy appliances (washing machine, dishwasher, air conditioning) during off-peak times to reduce your bill in case you have an indexed tariff.
  • Adjust contracted power: avoid paying for more than you need. For a typical two-person home, 3.45–4.6 kW is usually enough. Paying for extra power is money wasted without added comfort.
  • Take advantage of the Spanish climate: Spain has over 2,500 hours of sunlight per year. Use natural light and ventilate your home in the morning or evening during summer. In winter, open curtains and blinds during the day to enjoy solar heat.

Small Actions, Big Impact

  • Turn off appliances in standby mode.
  • Switch to LED bulbs.
  • Adjust the thermostat by a couple of degrees.
  • Install smart plugs to monitor consumption.

Smart Solutions for Expats: Make Your Home More Efficient

Managing and setting up electricity in Spain requires a different approach than you might be used to. Luckily, Spain offers advanced technology and flexible options to make adaptation easier.

 

  • Home automation and consumption control: smart thermostats, programmable plugs, and monitoring systems allow you to manage consumption from your phone. It's perfect for adjusting to Spanish schedules and applying Lagom effortlessly.
  • Compare and choose the right tariff: don’t settle for the first offer. As an expat, it’s important to understand how Spain’s energy system works and how your habits differ from a local household. This helps avoid surprises and use energy wisely.
  • Choose transparent, tailored electricity tariffs: when hiring electricity plans, it’s recommended to prioritize renewable energy.

Energy Efficiency Checklist for Your Spanish Home with a Lagom Approach

  • Request the EPC before signing a contract.
  • Estimate your annual consumption and adjust contracted power.
  • Make the most of natural light and ventilation.
  • Automate your home with smart devices.
  • Research companies and offers available to you.
  • Choose a tariff that suits your needs.

Applying Lagom in Spain doesn’t mean sacrificing comfort or wellbeing. It’s about finding a balance between your needs and efficient energy use. Understanding the EPC, adjusting contracted power, and selecting the right tariff allows you to:

 

  • Reduce costs and avoid bill surprises.
  • Maintain comfort at home.
  • Live sustainably and responsibly.

Your home, your energy, and your wellbeing stay in balance, and every decision you make positively reinforces your life—comfortably, simply, and efficiently.
