Find a GIRS accredited UIP

GIRS registered providers (also known as Utility Infrastructure Providers (UIPs) are able to undertake new gas connections, service alterations or disconnections, dependent on the scope of their accreditation.

Domestic customers who may be seeking to have work undertaken on their connection should see the National Grid's page for domestic consumers and homeowners to get more information.

Due to our independence, we do not provide quotations or recommend specific providers to undertake connections work.
