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 — finishing Touches — finishing touches such as flooring, painting, and installing fixtures complete the loft conversion.

“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 — electrical and Plumbing Installation — for a functional loft conversion, electrical wiring and plumbing may be necessary.

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

A good answer: The bigger it is, the more materials go into it. — ask before the quote rather than after.

“How does complexity of the design 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 any necessary structural changes change the price?”

A good answer: The work cannot be scheduled until this is known. — ask before the quote rather than after.

“What is not included?”

A good answer: Construction and Structural Work — the main construction phase involves transforming the loft into a usable space, which may require reinforcing the existing structure — get the exclusions named in the quote, because a loft conversion 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 — loft Extension — this is an extension built on top of the existing house, providing substantial additional space and often requiring complex construction work.

Getting the quote right

  • Any necessary structural changes — the work cannot be scheduled until this is known.
  • Size of the space — a wide job needs more equipment brought to site.
  • In writing before anyone starts — a message on Locufy counts

  1. Look firstSize of the loft — the bigger it is, the more materials go into it — that is what the loft conversion specialist is judging on the first visit, and a price given without it is a guess.
  2. Agree what is being doneComplexity of the design — 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 itselfAny necessary structural changes — the work cannot be scheduled until this is known — and anything found on the day that was not in that is priced before it is started.
  4. Check it togetherSize of the space — a wide job needs more equipment brought to site — walked against the written scope rather than against the feeling of it, while the loft conversion 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, materials used — bulky materials cost more to get to site.

Construction and Structural Work
The main construction phase involves transforming the loft into a usable space, which may require reinforcing the existing structure.
Electrical and Plumbing Installation
For a functional loft conversion, electrical wiring and plumbing may be necessary.
Finishing Touches

Dormer Loft Conversion
This involves extending the existing roof to create additional headroom and floor space, typically featuring a flat roof and vertical walls.
Velux Loft Conversion
This conversion uses roof windows to bring natural light into the loft while maintaining the existing roof structure, ideal for minimal structural changes.
Hip-to-Gable Loft Conversion
This involves altering a hip roof to a gable roof, effectively increasing the available space and allowing for larger windows.

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 — finishing Touches — finishing touches such as flooring, painting, and installing fixtures complete the loft conversion, because it is what a buyer's solicitor, an insurer or a lender asks for long after the loft conversion specialist has gone.
Test what was doneElectrical and Plumbing Installation — for a functional loft conversion, electrical wiring and plumbing may be necessary — 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. construction and Structural Work — the main construction phase involves transforming the loft into a usable space, which may require reinforcing the existing structure — 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 loft conversion specialist's card means something — loft Extension — this is an extension built on top of the existing house, providing substantial additional space and often requiring complex construction work.

Hiring a loft conversion specialist: questions people ask

The cost of a loft conversion can vary based on factors such as the size of the loft, the complexity of the design, and any necessary structural changes. Additional features like bathrooms or bespoke storage solutions can also increase the overall price.

A loft conversion usually takes between 6 to 12 weeks to complete, depending on the complexity of the project and the availability of materials. Delays can occur due to unforeseen structural issues or changes in design during the build.

Loft conversions are typically extensive projects that cannot be completed on the same day. However, if you need urgent repairs or modifications, some contractors may offer expedited services for specific tasks, but this will come at a higher cost.

Yes, many homeowners choose to book related services, such as electrical work or insulation upgrades, alongside their loft conversion. This can often lead to cost savings and a more streamlined process.

Out of scope work for a loft conversion may include significant external alterations to the property, such as changes to the roofline or extensions beyond the loft space. Additionally, landscaping or garden work is generally not included unless specified in the contract.

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