How Energy Comparison Northern Ireland Differs from the Rest of the UK
Six Key Differences Between NI and GB Energy Markets
Understanding these is essential before comparing. The NI market works differently in every dimension.
Separate Regulator
The Utility Regulator — not Ofgem. No automatic price cap. Tariffs approved independently. Comparison is essential.
Single Electricity Market
All-island market shared with Republic of Ireland. Different wholesale dynamics from GB. Larger-scale competition helps drive pricing.
Only 5 Suppliers
Power NI, Budget Energy, SSE Airtricity, Click Energy, and Share Energy. Cost difference can exceed £200/year for the same usage.
Gas Is Not Universal
Only available in parts of NI. Many households use home heating oil. Switch compares both gas and oil suppliers.
Security Deposits May Apply
£125–£150 if not paying by Direct Debit. Fully returned after 12 months of on-time payments. DD avoids this entirely.
10 Working Day Cooling-Off
Slightly different from the 14 calendar days in GB. Cancel within this window at zero cost with no penalty.
