Spanish communities of owners are overpaying up to 1,500 euros annually on their electricity bills and more than 3,500 euros on gas, according to a recent analysis by the OCU (Organization of Consumers and Users). The study, based on 85 electricity and 15 natural gas invoices from communities in the free market, reveals that most have uncompetitive tariffs and excess contracted power. This hidden cost, paid collectively by residents, often goes unnoticed but adds up significantly over the year.
What the OCU Analysis Found
The OCU examined invoices from communities of owners, all within the free market. The results show a clear pattern: most communities are on tariffs that are far from competitive, and many have contracted more power than needed. This combination leads to substantial overcharges that could be avoided with better energy management.
For electricity alone, the overcost from lacking a competitive tariff can reach 1,500 euros per year, based on a model community with 6.94 kW contracted and 5,500 kWh consumption. Additionally, 84% of the invoices analyzed had excessive contracted power, adding up to 314 euros more in unnecessary costs.

Why Communities Overpay on Electricity
The main issue is that communities often stick with legacy contracts or default tariffs without shopping around. Lack of awareness among property managers and residents leads to inertia, where bills are paid without scrutiny. Since the cost is shared, individual owners may not feel the urgency to optimize.
Moreover, excess contracted power is common because communities fear outages or were advised poorly. But modern energy management and efficiency measures can reduce the need for high power, cutting fixed charges significantly.
The Gas Bill Problem
Natural gas bills are even more alarming. The OCU found overcharges exceeding 3,500 euros per year for communities. This is partly due to similar issues: uncompetitive tariffs and possibly oversized contracts. Gas is often used for heating and hot water in common areas, making it a major expense that demands attention.
Switching to a competitive gas tariff and adjusting contracted capacity could yield substantial savings. Communities should review their gas contracts annually, just as they would for electricity.
How to Reduce Energy Costs for Communities
Taking action starts with a thorough review of current contracts. Compare tariffs from multiple suppliers and negotiate better rates. Consider installing energy-efficient systems, such as LED lighting and smart thermostats, to lower consumption.
Regular energy audits can identify waste and optimize contracted power. Engaging a specialized energy consultant may also help navigate the complex market and secure favorable terms.
- Review contracts annually to ensure competitive pricing.
- Adjust contracted power to match actual needs and avoid fixed-charge overpayment.
- Invest in efficiency upgrades like LED lighting and improved insulation.
- Educate residents about shared energy costs and conservation.
- Consider collective purchasing to leverage bargaining power.
Comparison of Potential Overcharges
The table below summarizes the key findings from the OCU analysis, illustrating the financial impact on communities. The background to this story is set out in Andy Burnham Cuts VAT on Electricity Bills to Ease Costs. A related thread runs through Andy Burnham Cuts VAT on Electricity Bills: £45 Savings.
| Energy Type | Potential Overcharge (€/year) | Main Cause |
|---|---|---|
| Electricity | Up to 1,500 | Uncompetitive tariff |
| Electricity (excess power) | Up to 314 | Contracted power too high |
| Gas | Over 3,500 | Uncompetitive tariff and excess capacity |
What This Means for Homeowners
These overcharges directly affect community fees, as the excess costs are passed on to residents. By addressing energy contracts, communities can reduce monthly expenses and potentially lower fees. It's a matter of financial prudence that benefits all owners. Earlier coverage in Andy Burnham's VAT Cut on Electricity Bills: What You Save shows how the argument developed.

With energy prices volatile, staying on outdated tariffs is risky. Proactive management can shield communities from future price hikes and ensure they are getting the best deal available.

FAQ
What did the OCU analyze in its study?
The OCU analyzed 85 electricity and 15 natural gas invoices from Spanish communities of owners, all within the free market. It found that most had uncompetitive tariffs and excess contracted power, leading to significant overcharges.
How much can a community save by switching tariffs?
According to the OCU, communities can save up to 1,500 euros per year on electricity and over 3,500 euros on gas by switching to competitive tariffs and adjusting contracted power.
Why is excess contracted power a problem?
Excess contracted power results in higher fixed charges on the bill, even if the energy is not used. 84% of the invoices analyzed had this issue, adding up to 314 euros in unnecessary costs per year.
What steps can communities take to reduce energy costs?
Communities should review contracts annually, compare tariffs, adjust contracted power to actual needs, invest in efficiency upgrades, and educate residents about conservation.
