What to check when hiring extension / renovation contractors in Ireland
MyTrustedTraders ranks on independent public evidence. No ads, no paid placement. Use these checks alongside the evidence on each profile before you decide who to contact.
- In Ireland, gas work must by law be done by a Registered Gas Installer (RGI) and electrical work by a contractor registered with Safe Electric. Verify the registration on the public register before any gas or electrical job, as using an unregistered installer is illegal and dangerous.
- Agree an itemised written quote with staged payments tied to completed work rather than a large cash deposit up front, and confirm the tradesperson's public-liability insurance before they start.
- Ask to see a portfolio of completed work like yours, plus recent references you can contact.
- Check the credentials and registrations that matter for this work, and that they are current.
- Get a written, itemised quote with scope, assumptions and a staged payment schedule.
How to judge an extension / renovation contractor
Independent, no-ads guidance. The trade-specific checks that matter most, the warning signs, and what to ask before you hire. Use it alongside each tradesperson’s public evidence above.
Verify before you hire
- Most extensions and major renovations need planning permission (or fall within exempted development limits) and come under the Building Control (Amendment) Regulations (BCAR): confirm planning and whether your job needs a Certificate of Compliance with an Assigned Certifier.
- Use a builder on the Construction Industry Register Ireland (CIRI, ciri.ie) who is registered on the CRO with tax clearance, and confirm public liability and employer's liability insurance.
- Insist on a written contract with a detailed scope, staged payments tied to milestones, and a retention held until snagging is complete.
- Ask about a structural warranty for significant works and confirm who certifies completion.
Warning signs of a cowboy
- Suggests skipping planning permission or BCAR certification to save time or cost.
- Not on CIRI or the CRO, or won't show insurance and tax clearance.
- Demands large cash payments up front, or has no written contract.
- A quote far below every other bid, or no clear completion sign-off.
Questions to ask before you hire
- Does this need planning permission and BCAR certification, and who is the Assigned Certifier?
- Are you on CIRI, and can I see your CRO registration, tax clearance and insurance?
- Can we agree a written contract with staged payments and a retention?
- What completion certification and guarantees will I receive?
Frequently asked questions
- How do I choose a trustworthy extension / renovation contractor?
- Compare the public evidence on each profile: how many independent reviews they have and across how many named sources, the rating and how recent it is, any credential evidence, and the company status. An extension / renovation contractor backed by several named sources is harder to fake than one found in only one place.
- Does MyTrustedTraders rank or recommend extension / renovation contractors for payment?
- No. There are no ads and no paid placement. Extension / renovation contractors are ranked only by the strength of independent public evidence. No one can pay to rank higher, add a badge, or change their reviews.
- Where do the reviews come from?
- They're imported from named public review sources and always shown with the source named. They aren't reviews written on MyTrustedTraders. We cross-check the same business across sources rather than creating new reviews.
- What should I check before hiring an extension / renovation contractor?
- Confirm credentials and insurance directly with the extension / renovation contractor, get a written quote, and run the Cowboy Checker on the business first. MyTrustedTraders helps you shortlist on the evidence. It doesn't replace your own checks before you hire.
