The Competition and Markets Authority released its final market study on 15 July 2026, concluding that recent price rises for domestic heating oil were driven by global wholesale costs rather than conditions within the United Kingdom.

In response to findings regarding dispute resolution mechanisms and assistance for at-risk families, the Northern Ireland Executive has introduced a mandatory code of conduct for retailers selling heating oil.

This new framework will enforce stricter rules on minimum order volumes, payment terms, delivery schedules, and associated charges to enhance clarity for customers.

A dedicated Home Heating Oil Working Group was formed to oversee implementation, drawing representatives from the Department for the Economy, the Consumer Council, and the Trading Standards Service.

Economy Minister Dr Caoimhe Archibald described the proposed interventions as proportionate, practical, and cost-effective while aiming to bolster existing safeguards.

Key elements include the creation of a comprehensive supplier register designed to work alongside HMRC's Registered Dealers in Controlled Oils scheme for better market oversight.

The Consumer Council will lead an opt-in register specifically targeting vulnerable consumers to ensure aid reaches those most affected by supply disruptions or fuel shortages.

Enhanced redress arrangements are also being developed to give the Consumer Council greater authority in resolving contract and service disputes between buyers and sellers.

The CMA's analysis noted that local competition remains robust, with prices currently among the lowest recorded across Britain and Ireland.

While the market is competitive, officials identified a clear requirement for improved consumer safeguards and more accessible channels for resolving disagreements.

Dr Archibald stated that the package of measures seeks to bring protections closer to those available in the gas and electricity sectors without imposing undue burdens on businesses.

The proposals aim to establish clearer routes for consumers seeking resolution when issues arise regarding their heating oil contracts or service delivery.

Implementation details are expected to be outlined by officials working within the newly established working group over the coming weeks.

Media enquiries regarding the matter can be directed through the Executive Information Service during standard business hours.
