BEFORE YOU BOOK

Check before you book

Construction Industry Register Ireland (CIRI)

CIRI is a VOLUNTARY register today. The Regulation of Providers of Building Works and Miscellaneous Provisions Act 2022 was signed on 5 July 2022 and S.I. 429/2022 commenced parts of it on 29 August 2022; the Construction Industry Federation was appointed registration body on 16 January 2023. Registration is NOT yet mandatory: the divisions regulations had not been drafted as of a May 2025 Dáil answer, and CIRI itself projects mandatory registration from 2027. So being absent from CIRI breaks no law in 2026 — and being on it is still the only independent check of a builder that exists here.

Search the Construction Industry Register Ireland for the name or the registration number before you agree a price. ciri.ie →

a Certificate of Compliance on Completion

Issued by the assigned certifier and the builder, where the work needed a commencement notice on completion, before the building is occupied. It matters because it is lodged on the statutory register and is what a buyer's solicitor looks for; work done without one surfaces on sale.

Agree before the work starts that you will be handed a certificate of compliance on completion, and keep it with the house papers.

Insurance

Expect public liability and, for anything structural, professional indemnity from whoever designed it. From a company, ask for the insurer, the limit and the VAT number, and ask who actually attends: the team that turns up may be employed, subcontracted or both, and only one of those is supervised by the firm you are paying.

Ask to see the current certificate of insurance — the insurer's name, the limit and the date it runs to.

Trader or private seller

Under the Consumer Rights Act 2022 a trader must tell you they are a trader, and your consumer rights — work carried out with reasonable skill and care, and a cooling-off period on a contract agreed in your home or online — apply to traders and not to private sellers. On Locufy the trader status is shown on the profile.

Look for the trader badge on the Locufy profile, and ask anyone else for it in writing before you agree a price.

VAT

VAT at 13.5%, the reduced rate Revenue publishes for this service. Ask whether the price you were given includes it. A trader under the €42,500 registration threshold does not charge it; one over it must, and must show it separately.

Ask whether the figure you were given includes it, and for the VAT number if they are registered — Revenue publishes the rate for this service. revenue.ie →

“Are you on the Construction Industry Register Ireland, and what is your number?”

A good answer: A number you can look up yourself before you agree a price — designing a mitigation — designing a mitigation plan if needed.

“Will I get a Certificate of Compliance on Completion, and when?”

A good answer: On the day the work is finished and tested, not posted on later — initial radon testing — initial radon testing in the property.

“How does size of the property change the price?”

A good answer: A large job ties up a whole day rather than part of one. — ask before the quote rather than after.

“How does complexity of the mitigation required change the price?”

A good answer: Detail work cannot be rushed, so it costs more per hour on site. — ask before the quote rather than after.

“How does existing infrastructure change the price?”

A good answer: The state it is in decides how much has to come off first. — ask before the quote rather than after.

“What is not included?”

A good answer: What does this service include? — this service typically includes radon testing, analysis, and installation of mitigation systems if necessary — get the exclusions named in the quote, because a radon specialist job is priced on what was agreed and not on what was assumed.

“Who insures you, and what is the policy number?”

A good answer: Expect public liability and, for anything structural, professional indemnity from whoever designed it — maintenance of Mitigation Systems — providing regular checks and maintenance of installed radon mitigation systems.

Getting the quote right

  • Size of the property — a large job ties up a whole day rather than part of one.
  • Complexity of the mitigation required — detail work cannot be rushed, so it costs more per hour on site.

  • What does this service include? — it sets how much preparation the job needs.
  • In writing before anyone starts — a message on Locufy counts

  1. Look firstSize of the property — a large job ties up a whole day rather than part of one — that is what the radon specialist is judging on the first visit, and a price given without it is a guess.
  2. Agree what is being doneComplexity of the mitigation required — detail work cannot be rushed, so it costs more per hour on site — put in writing before anyone starts, because it is the document you both read back at the end.
  3. The work itselfExisting infrastructure — the state it is in decides how much has to come off first — and anything found on the day that was not in that is priced before it is started.
  4. Check it togetherWhat does this service include? — it sets how much preparation the job needs — walked against the written scope rather than against the feeling of it, while the radon specialist is still there.
  5. What you are handedA Certificate of Compliance on Completion, the invoice and any guarantee on the workmanship and the parts, check for any local regulations regarding radon testing and mitigation.

AFTER

When the job is done

Keep a Certificate of Compliance on CompletionA Certificate of Compliance on Completion is issued by the trader, not asked for later — designing a mitigation — designing a mitigation plan if needed, because it is what a buyer's solicitor, an insurer or a lender asks for long after the radon specialist has gone.
Test what was doneInitial radon testing — initial radon testing in the property — and something that does not work on the day is theirs to put right there and then.
Ask what the guarantee isOn the workmanship and on the parts, and for how long each one runs — they are usually different. what does this service include? — this service typically includes radon testing, analysis, and installation of mitigation systems if necessary — under the Consumer Rights Act 2022 what was agreed is what can be relied on.
Leave the reviewOnly a booked job can be reviewed on Locufy, which is why the score on a radon specialist's card means something — maintenance of Mitigation Systems — providing regular checks and maintenance of installed radon mitigation systems.

Hiring a radon specialist: questions people ask

Yes, testing for radon is important for health reasons, as prolonged exposure can lead to serious health issues. Consider the age and construction type of your property, as these can affect radon levels.

If high levels are detected, a mitigation plan will be developed to reduce radon exposure effectively. Radon testing and mitigation is a crucial service aimed at identifying and reducing radon gas levels in residential and commercial properties.

While DIY kits are available, professional testing is recommended for accurate results and proper mitigation. The process typically involves measuring radon concentrations in the air and, if necessary, implementing solutions to lower exposure to this harmful gas.

It is advisable to test for radon every two years or after any major renovations. Be aware that mitigation systems require regular maintenance for continued effectiveness.

Search the name or the registration number. If the number does not resolve to the name on the quote, stop there.

Under the Consumer Rights Act 2022 the work must be carried out with reasonable skill and care, and put right if it is not. Say what is wrong in writing first.
