This ensures you only connect with legitimate, stable building businesses.

What should I check before hiring a builder in Ireland?

Ensure a clear written contract is signed before paying any deposit.

How much does a home extension cost in Ireland in 2025?

In 2025/2026, home extension costs in Ireland range from €2,000 to €3,500 per square metre. A standard 30 m² ground-floor kitchen extension typically costs between €60,000 and €90,000, depending on structural steel requirements, glazing systems, and internal finishes.

Do builders in Ireland need to be registered?

While there is no mandatory single register for all builders, professional builders are typically registered with CIRI (Construction Industry Register Ireland), the National Guild of Master Craftsmen, or have active CRO company registrations. Specialist work like electrical and gas must be done by certified RECI/RGII contractors.

What is the difference between a general builder and a main contractor?

A general builder typically executes hands-on building work with a small crew. A main contractor oversees the entire project, manages subcontractors (plumbers, electricians), coordinates structural engineers, handles building control compliance, and is legally responsible for safety on site under health and safety regulations.

How long does a home extension take in Ireland?

A standard single-story ground-floor extension (30 m²) typically takes 10 to 16 weeks to construct. A larger double-story extension can take 16 to 24 weeks. The timeline includes foundations, brickwork, structural steels, roofing, glazing, plumbing/electrical first-fixes, plastering, and final finishes.

Should I get planning permission before hiring a builder?

Yes, you should secure planning permission (or verify the project falls under the 40 m² exempted development rule) before hiring a builder. Builders require approved structural drawings and architectural plans to provide accurate, binding quotes and ensure the build complies with Irish building regulations.

What is a fair deposit to pay a builder in Ireland?

A fair deposit is typically 10% to 15% of the total contract value, paid upon signing the contract to secure the slot and purchase initial materials. Never pay a large deposit upfront. Set up a structured payment schedule based on verified milestone completions (e.g., foundation, roof, plastering).
