Efficient Solutions for Shared Electricity Bills in Sri Lanka: Ensuring Fairness and Transparency



In recent times, residents in Sri Lanka, particularly in Colombo, have been facing challenges when it comes to sharing electricity bills among multiple families living in the same house. The existing billing system, which calculates charges based on units consumed, often leads to discrepancies and misunderstandings. Additionally, the rising fixed charges further complicate matters. In this article, we will explore effective solutions to address this issue without the need for installing new meters, allowing families to share bills fairly and transparently.

Living in shared accommodation with multiple families is a common practice in Sri Lanka, particularly in cities like Colombo. However, one issue that often arises is the calculation and sharing of electricity bills. With the increasing cost of electricity, it’s essential to find a fair and convenient way to split the bills without causing disputes or financial strain on one party.

Many utility providers in Sri Lanka use a tiered pricing system for calculating electricity bills, where the cost per unit increases as usage increases. This system can be problematic for families sharing a meter as it’s challenging to split the bill equally if one family uses more electricity than the other. Additionally, fixed charges, which are often a flat rate, can also increase, making it more difficult to share costs equitably.

One solution to this problem is to install a private meter for each family. This way, each family can monitor their energy consumption and pay for what they use. However, this method can be expensive, and if the unit price changes, calculating each family’s share can be complicated.

Fortunately, there are alternative solutions that can help families share electricity bills without having to install new meters.

One approach is to divide the total bill into equal parts, regardless of usage. This method works best when all families have similar lifestyles and energy consumption patterns. However, if one family uses significantly more energy than the others, it can cause resentment and disputes.

Another option is to calculate the electricity bill based on occupancy, where each family pays a portion of the bill based on the number of people living in the house. This method is fairer than the first option as it takes into account the number of people using electricity, rather than just the total usage.

Lastly, families can consider using energy-efficient appliances and practices to reduce their overall energy consumption. This will not only help save money on electricity bills but also reduce their carbon footprint

1. Clear Communication and Agreement:

The first step in resolving shared electricity bill concerns is open and transparent communication among the families involved. By discussing the issue and reaching a mutual agreement on how to divide the bills, conflicts and misunderstandings can be minimized. It is essential to consider factors such as the number of occupants, usage patterns, and the size of each family unit.

2. Energy Allocation System:

Implementing an energy allocation system can help distribute electricity costs fairly. This involves setting a baseline allocation for each family and using additional units consumed to determine the proportionate increase in charges. For instance, if one family consumes twice the allocated units, their share of the bill would be twice the base amount. This approach ensures a more equitable distribution of costs.

3. Shared Expense Tracking:

Maintaining a shared expense tracking system can aid in accurately recording and allocating electricity expenses. This can be done by creating a dedicated ledger or using digital apps that allow families to input their monthly electricity usage. By transparently tracking individual consumption, it becomes easier to calculate each family’s share accurately.

4. Advanced Metering Solutions:

While avoiding the need for new meters is preferred, it’s worth exploring advanced metering solutions for shared properties. Smart meters with the capability to measure individual unit consumption can offer a more precise and fair billing system. These meters can provide real-time data, enabling families to monitor their usage, identify wasteful practices, and adjust their behavior accordingly.

5. Advocacy and Engagement:

Engaging with the electricity distribution authorities and local representatives can be a proactive step toward addressing this issue on a broader scale. By advocating for fair billing practices and raising awareness about the challenges faced by shared households, it is possible to drive changes in policies and regulations. This collective effort can result in a more inclusive and just system for shared electricity billing.


Shared electricity billing challenges faced by families living together in Colombo can be effectively addressed through clear communication, energy allocation systems, shared expense tracking, and engagement with authorities. While advanced metering solutions offer a more accurate billing approach, existing methods can still ensure fair distribution without the need for additional meters. By implementing these solutions and promoting fairness, transparency, and efficiency, families can navigate shared electricity bills in a mutually beneficial manner. Sharing electricity bills in a shared living situation can be challenging, but there are solutions available. By considering each family’s needs and lifestyle, it’s possible to find a fair and convenient way to split the costs without causing disputes or financial strain. With a little planning and cooperation, families can enjoy their shared living arrangement without worrying about electricity bills.
