How do you start a solar PV installation company in Ireland and get it SEAI-registered?

What does SEAI require from a solar PV company?

SEAI registers the company and the installer separately, and each has its own list. The company needs a registered installer, an insurance declaration and a quality management system. The installer needs solar qualifications and an electrical registration. Both lists are on SEAI's solar PV scheme page.

Registration with Safe Electric is a legal requirement for electrical contractors, so an established electrical contractor may already hold the personal side. The company-level paperwork is the new part. Building the team from scratch? See solar PV installer qualifications.

Heat pumps under SEAI's Better Energy Homes scheme are a separate contractor registration route with its own requirements, including renewable energy installer registration, an insurance declaration, tax clearance and an onboarding webinar.

What goes into the quality management system?

SEAI names four parts: an organisation chart, document control, a complaints process and quality control. The examples below are our suggestions for a small firm, not SEAI wording, so check them against the quality guidance SEAI links from the scheme page before you submit.

The organisation chart shows who signs off designs, who supervises installations and who answers a customer complaint. Document control means one place where the current version of every procedure, checklist and template lives.

The complaints process says how a complaint is logged, who replies and what happens next. Quality control is the check after each job, for example a sign-off checklist per installation kept on file. Keep it short enough that your team will actually use it.

How long does SEAI registration take?

SEAI says up to five weeks from when it receives all the correct documentation, depending on when you apply. Registration is not complete until the monthly onboarding is done, so the date of the next session matters.

Work backwards from your first job: allow the five weeks plus the time it takes to write your quality system, and ask SEAI to confirm the next session date when you apply. Missing documents are the part you control, because the five weeks run from complete papers.

What happens in the six-month provisional period?

SEAI registers a new solar PV company provisionally for six months, counted from its first installation. After that, the scheme page sets a satisfactory inspections pass rate and a minimum of five installations a year, and says failing to meet them may result in deregistration.

The clock starts with the first installation, not the registration date, so you decide when it starts. Ask SEAI how it counts the first year before you plan a slow start. Before you install your first system, have these ready:

• Registration complete, including the monthly onboarding
• A registered installer who is an owner, director or direct employee
• Insurance cover and a written quality management system
• A customer who has signed a written supply-and-install contract
• SEAI grant approval in place before any work starts
• Materials lined up
• A quality control record ready to fill in from day one

How do you win your first five installations?

Start with people who already trust you: existing electrical customers, builders you work with and the neighbours of past jobs. Registration lets you into SEAI's solar scheme. It does not bring customers.

Demand is there. SEAI reported on 29 September 2026 that over 120,000 homes have been supported with solar, and applications to its home energy upgrade grants rose 96% year on year in the first quarter of 2026. The field is crowded too: SEAI's online list shows more than 500 solar PV firms (SEAI register, November 2026).

Homeowners can compare you with many listed firms, so a fast, clear reply, a written supply-and-install contract and grant paperwork the homeowner does not have to chase help you win the quote. More in selling with the SEAI solar grant.

Beyond your own network, installers use several channels. SEAI publishes a register that homeowners can browse. According to their own websites in November 2026, Bark works on credits you buy to contact customers, and OnlineTradesmen.ie on a monthly membership with no tie-in. Lead services pass on homeowner requests; compare them with where to buy solar leads and qualifying solar leads.

Smart Solar is one such service, not a route around registration. It passes on solar PV enquiries from private homeowners to installers and installs nothing itself. Homeowners ask for quotes on smart-solar.ie or through a Facebook ad form. The service is free for the homeowner, and the installer pays for enquiries passed on. They are not exclusive and can be shared with other installers. You choose counties or Eircode areas and a weekly cap, which is a maximum, not a guarantee. Our homeowner terms say we work only with installers registered for the job, so you need SEAI registration before you sign up with us. We promise no volume of enquiries or jobs.

Can you start as a subcontractor to a One Stop Shop?

Yes, once you are registered. SEAI's support page for One Stop Shops says a contractor registered with SEAI can work as a contractor or subcontractor for an existing One Stop Shop. A One Stop Shop manages the upgrade for the homeowner. SEAI's list showed 32 registered One Stop Shops in November 2026. For solar PV, SEAI's grant page says a homeowner can use a One Stop Shop only when getting several upgrades at once, and that the grants are then deducted upfront.

Becoming one yourself is a different level. SEAI's One Stop Shop registration page lists, among other criteria, a minimum annual turnover of €1 million and the ability to offer the full range of energy upgrades, in two stages: pre-qualification and a strategic plan. A new firm may not meet the turnover test, so subcontracting is the route to consider first.

Ask each One Stop Shop directly what it requires, including whether it will use a firm that is still in its provisional period. More in working with SEAI One Stop Shops.

Step by step: from company set-up to your first grant-funded job

Seven steps take you from a new company to a first grant-funded job, and the order matters.

1. Set up the company and tax registration. SEAI asks the installer for a tax reference and Tax Access Number, so have these in place before you apply.
2. Secure your registered installer. Either you qualify yourself or you employ someone who does, as an owner, director or direct employee.
3. Arrange insurance. SEAI asks for a company Declaration of Insurance in the online registration, so sort cover with your broker early.
4. Write the quality management system. Cover the organisation chart, document control, complaints process and quality control.
5. Submit complete papers and join the next monthly onboarding. Allow up to five weeks for processing.
6. Line up your first customer before you install. The grant approval must be in place before work starts, with eight months to finish after approval, as of November 2026.
7. Contract supply and installation together, then document every job. Aim for five installations a year as your floor.

Step 7 matters for VAT. Revenue's eBrief 105/23 announced the new zero rate for solar panels. Revenue's manual says it applies from 1 May 2023 on or beside private dwellings, that supply alone is charged at the standard rate, and that the zero rate does not cover commercial buildings or short-term holiday lets. Check the details in our guide to VAT on solar installations and with Revenue or your accountant before you price your first job.

Typical mistakes when starting a solar installation business

Most of these come from treating registration as the finish line rather than the start of selling.

• Applying with an unfinished quality system. The five-week figure runs from complete papers.
• Treating the installer as a freelancer on call. SEAI asks for an owner, director or direct employee.
• Starting the first job before grant approval is in place.
• Quoting supply only. The zero VAT rate depends on a supply-and-install contract.
• Assuming registration brings customers. You join a register that already lists many firms. Read the Irish solar installer market before you set sales targets.
• Budgeting a registration fee from a forum. Safe Electric publishes its fees and the SEAI pages we read state none, so check both before you budget.
