Who is the Best Business Electricity Supplier in Ireland?
The best electricity supplier for your commercial meter will vary over time, depending on a suppliers appetite to take on new business.
Electricity suppliers also have different target markets, and your usage profile and meter category play a key role in determining which supplier is the best fit for you. For example – Certain electricity suppliers focus on large energy users, while others specialise in SMEs. Some suppliers offer a lower night rate, but charge a higher day rate. A few suppliers only offer fixed-unit prices, while others offer both fixed rates and wholesale tracker plans.
In summary, there is no one size fits all. Utilityfair's energy advisors can tell you in minutes which supplier is the best fit for you by looking at a recent electricity bill – it's free so, please, get it touch.

- Electric Ireland
- Energia
- Bord Gáis Energy

- Pinergy
- Yuno
💡 Pro tip: The electricity supplier offering the lowest rates today may not be the same tomorrow. Business electricity prices shift with supplier appetite to take on new business, market conditions and wholesale energy costs. Larger energy users can volume discounts and as such having a broker that is familiar with market rates to help you negotiate is advantageous.
Which Energy Suppliers offer 100% Renewable Business Electricity?
It is possible to source renewable energy from most energy suppliers in Ireland. Some suppliers fully utilize renewable energy for their entire supply, while others do not. Even if a electricity supplier does not offer 100% renewable energy by default, Utilityfair can still secure 100% certified renewable electricity – as they often ringfence their renewable supply for specified customers.
💡 Example: One of our clients has several department stores with a combined electricity usage of 15 GWh. They have strict sustainability targets that requires 100% certified renewable electricity supply. Utilityfair has negotiated 100% certified renewable supply with guarantees of origin from one of Ireland largest suppliers. The same supplier is not renewable across their full portfolio. Our energy experts can negotiate renewable supply at best pricing from almost all suppliers.
It is important to note that reported renewable fuel mix does not necessarily represent actual electricity generation in Ireland. Electricity suppliers can claim the benefits of renewable electricity generated outside of Ireland by using traded electronic certificates called Guarantees of Origin (GOs).
