How to find a builder in Ireland is really a question about how to verify one, because there is no licence to verify against. Anyone can call themselves a builder and start quoting tomorrow. Gas work is regulated, electrical work is regulated — but the person coordinating your entire renovation is not, and the statutory register that will one day change that is not yet in force for the builder pricing your bathroom.
That is why how to find a builder is the wrong first question and how to vet one is the right one. The vetting is a stack of checks a homeowner assembles from registers and public records before money changes hands — a sequence that separates a firm you can hold to account from one that disappears when the snag list appears.
Ireland does not yet licence builders. Until the statutory register arrives, the vetting is yours to run — from public records.
What follows is that verification stack in order — the register that exists today, the registrations that are already the law, the insurance and company checks, and the contract and consumer rights that sit behind all of it.
Why is finding a builder in Ireland entirely your job
Because no body licenses general builders in Ireland today. The Regulation of Providers of Building Works Act 2022 was enacted to change exactly that — it puts the Construction Industry Register Ireland (CIRI) on a statutory footing, with the Construction Industry Federation appointed as registration body — but the sections that make registration mandatory have not yet been commenced. Mandatory registration is due to phase in during 2026, and the first categories to be regulated are builders of housing developments and multi-unit schemes, not the firm renovating a single home.
The practical position for a homeowner hiring this year is unchanged: registration is voluntary, and the vetting burden sits with you. The regulation Ireland does enforce sits on specialist tasks — gas and electrical work — and on the paperwork around the project: the Commencement Notice regime set out by Citizens Information, the certificates each registered trade must issue, and the consumer law behind the contract. A prepared homeowner builds the check from those pieces.
How to find a builder you can actually verify
Verification is not one check but a stack of them, each catching what the last one misses. A builder who passes all six is not guaranteed perfect — but one who fails any of them has told you something before you have paid a cent. Run these in order:
- Register check. Look the firm up on the Voluntary Construction Register — the CIF-operated register formerly known as CIRI — rather than trusting a logo on a van or a website.
- Company check. Search the company on the Companies Registration Office's CORE portal for its age, its filing history, and the record of the people behind it.
- Trade registrations. Confirm that any gas work will be done by a Registered Gas Installer and any electrical work by a Safe Electric registered electrical contractor — both legal requirements, both checkable online.
- Insurance. Get written confirmation of current public liability insurance, and employer's liability cover where the firm has staff, with policy dates and limits visible on the certificate.
- References. Visit a completed job — ideally one a year or two old — and ask that homeowner how the snag list, the payment schedule, and every variation were actually handled.
- Contract. Establish that the builder will work to a written contract and a fixed-price quotation, not a verbal estimate, before any deposit is discussed.
The register layer is where most homeowners stop, and it is the weakest place to stop. A register entry tells you the firm met admission criteria; it does not tell you the company's finances today, who stands behind it, or how it behaves at the snag list. That is what the remaining five checks are for.

What does the Construction Industry Register Ireland actually tell you
CIRI is in transition, and knowing which version you are looking at matters. The statutory register created by the 2022 Act will eventually make it an offence for an unregistered provider to carry out building works in regulated categories. Until those sections commence, the register that exists is the renamed voluntary one: the Voluntary Construction Register, operated by the Construction Industry Federation, listing builders, contractors, and specialist trades that have met its admission criteria. The old ciri.ie address itself states it is offline until mandatory registration begins.
Read the register for what it is. Inclusion is a meaningful positive signal — the firm submitted itself to vetting it was not obliged to undergo — but it is voluntary, so absence is not proof of a problem, and presence is not a guarantee of workmanship. It is one layer of the stack, not the stack.
Today: check the Voluntary Construction Register, and treat inclusion as a positive signal rather than a licence.
Coming: mandatory CIRI registration phases in from 2026, starting with larger housing developers — the builder renovating a single home is not yet in a regulated category, so the rest of this stack is still doing the real work.
Which registrations are the law: gas and electrical
Two registrations are not optional, and they anchor the whole vetting exercise because they are criminal-law requirements rather than quality marks. Any work on a domestic gas installation must be carried out by a Registered Gas Installer — the RGI register is searchable online, and the regulator has prosecuted individuals for carrying out gas works while unregistered. Restricted electrical works must be carried out by a Safe Electric registered electrical contractor, who must issue a Completion Certificate when the work is done.
The certificates matter as much as the registrations. A builder who coordinates an unregistered electrician has produced a room with no Completion Certificate — a gap a buyer's solicitor will find at resale. Ask the builder, before accepting any quote, exactly who will do the gas and electrical work, confirm those names against the registers, and confirm in writing that the certificates are included in the price. A builder who hesitates on any of those three has answered the vetting question for you.
What insurance, tax, and company checks protect you
Insurance is the check that protects your house rather than the builder's. Ask for written confirmation of current public liability insurance — the cover that responds if the works damage your property or a neighbour's — and employer's liability cover where the firm has employees. Ireland sets no statutory minimum for either, which is exactly why the check is documentary: a current certificate, dates that span your project, limits appropriate to the job, and a trade description that matches the work. A builder who cannot produce the certificate is asking you to carry their risk.
Tax behaviour is a character check disguised as arithmetic. Renovation services are generally charged at the reduced 13.5% VAT rate under Revenue's two-thirds rule, provided materials do not exceed two-thirds of the total price — on a €20,000 job priced ex-VAT, the gap between 13.5% and the standard 23% is €1,900, which is why the rate on the quote is worth reading. An offer to knock off the VAT for cash is an invitation to tax fraud with no invoice, no paper trail, and no recourse when the work fails. And where the work is grant-aided — an SEAI energy upgrade, for instance — only a registered contractor holding a current Tax Clearance Certificate and declared insurance can do it at all.
The company check closes the loop. The CORE search shows when the company was incorporated and what it has filed — and a very new company behind a very confident website, or a principal whose previous companies were struck off, is a pattern you want to find before contract, not after. It costs nothing to look.
What contract and consumer rights protect you
The contract is where the vetting converts into protection. The Consumer Rights Act 2022 requires services supplied to consumers to be provided with due skill and care, and the Competition and Consumer Protection Commission is blunt about the sector's record: home building and improvement generated almost 1,250 complaints to its helpline in the first half of 2025 — the second-biggest driver of consumer contacts — and the CCPC wrote to almost 3,000 traders reminding them of their obligations. The recurring complaints are the preventable ones: work not started after a deposit, traders not returning to fix defects, and prices that moved without agreement.
The defence is written and staged. Agree a written contract that fixes the scope, the price, the timeline, how any variation will be priced and agreed, and a payment schedule that keeps money behind work: a modest deposit, staged payments against completed stages, and a meaningful final payment held until the snag list is cleared at practical completion. How to read the quotation that contract is built on — VAT, provisional sums, exclusions, payment structure — is set out in how to read a renovation quote in Ireland, and who answers for planning permission and the Commencement Notice is covered in the planning permission guide for Irish renovations.
That whole sequence — register, company, registrations, insurance, references, contract — sits in the early phases of The 12-Phase System, Property Blueprint Co.'s framework for running a renovation from the first quote conversation to final sign-off, set out in full in the 12 phases of a renovation in Ireland. Finding a builder in a country that does not yet license them is not a leap of faith. It is a checklist, run in order, before the money moves. The Renovation Blueprint systems carry that checklist room by room, from The Kitchen Renovation Blueprint to The Full Home Renovation Blueprint.

Frequently asked questions
Do builders need a licence in Ireland?
No. There is no licence for general builders in Ireland today. The Regulation of Providers of Building Works Act 2022 creates a statutory register — CIRI — but the sections making registration mandatory have not yet been commenced, and the first regulated categories are expected to be larger housing developers rather than domestic renovation firms. Only gas and electrical work carry legally required registrations, so vetting a builder remains the homeowner's job.
What is CIRI and is it mandatory yet?
CIRI is the Construction Industry Register Ireland, the statutory register created by the 2022 Act with the Construction Industry Federation as registration body. It is not yet mandatory: the commencement of the mandatory sections is phasing in from 2026, category by category. In the meantime the voluntary register has been renamed the Voluntary Construction Register, and inclusion on it is a positive signal rather than a legal requirement.
What registrations are legally required for trades in Ireland?
Two. Any work on a domestic gas installation must be carried out by a Registered Gas Installer, and restricted electrical works must be carried out by a Safe Electric registered electrical contractor who issues a Completion Certificate. Both are criminal-law requirements and both registers are searchable online, so confirm the named installer and electrician against them before accepting a quote.
What insurance should an Irish builder have?
Current public liability insurance, which responds if the works damage your property or injure a third party, and employer's liability insurance where the firm has employees. Ireland sets no statutory minimum for either cover, so the check is documentary: ask for the certificate, confirm the dates span your project, and confirm the limits and trade description match the work being done.
What VAT rate should a builder charge in Ireland?
Renovation and repair services to a home are generally charged at the reduced 13.5% rate under Revenue's two-thirds rule, provided the cost of materials does not exceed two-thirds of the total price; otherwise the standard 23% rate can apply to the whole job. Confirm whether the quote is VAT-inclusive and which rate applies, and treat any offer to drop the VAT for cash as the end of the conversation.
How much deposit should I pay a builder in Ireland?
A modest deposit to secure a start date is normal; a demand for a large upfront payment before work starts is a warning sign the CCPC's complaint statistics repeatedly reflect. Structure the schedule so money follows work: staged payments against completed and inspected stages, and a meaningful final payment held back until the snag list is cleared at practical completion, because that retained sum is your leverage.
