Solar grid connection in Northern Ireland: who handles the paperwork?

If you are comparing solar installers in Northern Ireland, ask who will handle the network connection paperwork before you accept a proposal. NIE Networks says your installer will advise which connection rules apply and will typically make the required application on your behalf. That makes responsibility for the paperwork a useful point to confirm in writing, rather than assume. NIEN - G98/NI installations

This guide answers a practical question: what should your installer arrange, and what will you still need to do yourself?

Which solar connection route applies to your home?

NIE Networks describes G98/NI as the rules for connecting micro-scale generation, such as solar panels, that exports electricity to the network. Its guidance distinguishes between G98/NI and G99/NI according to the equipment’s export characteristics. Ask your installer to identify the applicable route for your proposed system and explain the basis for that choice. Do not assume every domestic solar proposal follows the same process.

Within G98/NI, NIE Networks distinguishes between a single installation at a site, which generally follows its commissioning notification route, and multiple installations at a site, which require an application for network assessment before installation and commissioning can proceed through the stated process.

For your comparison notes, ask:

• Which NIE Networks connection route does this proposal require?
• Will you submit the application or commissioning documents on my behalf?
• Does the proposal depend on a network assessment before work proceeds?
• What documents will I receive to show what has been submitted?

These questions help you compare the proposed service, not just the equipment list.

What happens after installation?

For the G98/NI single-installation route described in its guidance, NIE Networks says the installer installs and commissions the equipment, then submits commissioning documentation within a specified deadline. NIE Networks reviews the documents and then arranges an import/export meter if the site does not already have one. NIEN - G98/NI installations

Ask the installer to confirm the current submission deadline and who will track the submission. Also ask how you will be told whether a meter needs to be fitted. The published sequence is not a guaranteed completion date for your property.

Could the local network need work?

For the G98/NI route involving multiple installations at a site, NIE Networks says it assesses whether the local electricity network can receive the proposed exported electricity. If an upgrade is needed, it will produce a quote and design for the network work. This is a possible outcome of that assessment, not a statement that every home needs an upgrade. NIEN - G98/NI installations

If your proposal uses that route, ask what remains subject to assessment, whether any network work is included in the installer’s price, and how an additional requirement would affect your decision to proceed. Do not treat an installation proposal as confirmation that the network assessment has been completed.

Does network paperwork also arrange export payments?

No. NIE Networks explicitly says that you need to approach an electricity supplier to enter into a purchase contract for exported electricity. It has no involvement in that contract, which is between you and the supplier. Completing the network process should therefore not be treated as confirmation that an export payment agreement is in place. NIEN - G98/NI installations

Keep separate notes for the network paperwork, metering and supplier contract. For related reading, see the site’s guide to solar export payments in Northern Ireland.

What to confirm before accepting a solar proposal

Ask for a written explanation of the connection route, responsibility for submissions, any assessment still outstanding, and what happens if network work is required. Separately, identify who you will contact about purchasing your exported electricity. These checks turn a general promise to handle the installation into responsibilities you can discuss and compare.

Northern Ireland scope and source date

This article uses NIE Networks’ G98/NI installations guidance, checked on 24 October 2026. The supplied source does not state a publication or revision date, so that is a checking date, not the date the rules changed. The guidance is specific to Northern Ireland and should not be substituted with an assumption about procedures elsewhere in the UK.
