Buying a New Build in Ireland: What to Know Before You Sign Contracts

New builds are where most of Ireland's state support for first-time buyers concentrates. The Help to Buy scheme (up to €30,000), the First Home Scheme (shared equity up to 30%), and green mortgage rates that are 0.2% to 0.4% lower than standard products all apply exclusively to new builds. That financial stack is genuinely powerful — but new builds come with their own set of complications that buyers often discover too late.

Why New Builds Make Financial Sense for First-Time Buyers

A first-time buyer purchasing a qualifying new build can access:

• Help to Buy (HTB): A refund of up to €30,000 in income tax and DIRT paid over the preceding four tax years, applied directly to the 10% deposit
• First Home Scheme (FHS): State shared equity of up to 30% of the purchase price (or 20% if combined with HTB) to bridge the gap between mortgage capacity and purchase price
• Green mortgage rates: A-rated new builds qualify for discounted rate products starting around 3.4% at major lenders
• No pyrite or mica risk: New builds carry a 10-year HomeBond or Premier Guarantee structural warranty

The combined effect of HTB and FHS can dramatically reduce the cash deposit required and expand the price range available to buyers who are otherwise constrained by Central Bank borrowing limits.

What the HTB Scheme Means for Your Deposit

On a €380,000 new build:

• 10% deposit required: €38,000
• HTB maximum refund: €30,000 (10% of €300,000 is less, so the limit is €30,000)
• Remaining deposit from savings: €8,000

A buyer who has paid sufficient income tax in the preceding four years to access the full €30,000 refund can purchase a €380,000 home with only €8,000 in personal cash savings (plus closing costs). Without HTB, they'd need €38,000 saved.

The refund is paid by Revenue directly to the developer as a credit against the contract deposit, not into the buyer's account.

Construction Delays: The Biggest Practical Risk

New builds do not come with guaranteed completion dates. Planning conditions, material supply disruptions, subcontractor availability, and developer cash flow issues can all push out the actual completion date by months. In the Irish market, delays of three to twelve months beyond the initially indicated completion timeframe are common, not exceptional.

This creates a planning problem for buyers:

Lease expiry mismatches: If your rental agreement expires several months before your new build is complete, you either need to negotiate a short-term extension (which landlords are increasingly unwilling to offer) or find interim accommodation. Budget for the possibility of renting for longer than expected.

Mortgage approval expiry: AIP letters are typically valid for six months, renewable with updated documentation. If construction takes longer than anticipated, you may need to renew your AIP one or more times. Ensure your financial circumstances haven't changed materially between the original approval and drawdown — lenders can reassess at the point of drawdown.

Cost inflation: The price agreed in the contract is fixed, but if you've committed to upgrades or extras with the developer that are priced separately, be aware of any clauses that allow cost variation.

What "Off-Plan" Means and What You're Actually Buying

Many new builds in Ireland are sold "off-plan" — meaning you sign a contract before the property is built, based on architectural plans, show homes, and developer specifications. You're contractually agreeing to purchase something that doesn't yet physically exist.

Before signing contracts off-plan:

• Review the floor plans and specifications carefully with your solicitor
• Confirm exactly what finishes, fixtures, and fittings are included in the purchase price versus available as upgrades
• Understand the developer's process for changes between planning and completion
• Check the track record of the developer — completed projects, planning history, financial standing

Your solicitor's job is to review the contracts and specifications and advise you on any unusual clauses, particularly around completion dates, price variation, and what happens if the developer goes into receivership before completion.

HomeBond and Premier Guarantee: What's Covered

New builds in Ireland are typically covered by a ten-year structural warranty from either HomeBond or Premier Guarantee. These warranties cover major structural defects — issues with foundations, load-bearing walls, and the main roof structure — during the warranty period.

What they typically don't cover:

• Normal settlement cracks (hairline cracks in plasterwork during the first few years are expected)
• Cosmetic defects after the initial snagging period
• Defects resulting from improper owner use or modification
• The full cost of pyritic heave or defective concrete blocks (though new builds shouldn't have this issue)

Before drawdown, your solicitor will confirm that a HomeBond or Premier Guarantee certificate has been issued for the property. Do not proceed to drawdown without this — it's a significant protection gap if the warranty is absent.

The Snag List: Your Final Opportunity Before Handover

Before accepting keys, commission an independent snag list from a professional inspector. The developer is legally required to deliver the property to the agreed specification, and the snag list documents every deviation.

Professional snag costs run €300 to €600 depending on property size. The cost is insignificant compared to the value of having documented evidence of defects that the developer must remedy. Do not accept the developer's sales representative telling you the property is ready without independent verification.

Budget for the snag to identify 50 to 150 items on a typical three-bedroom new build. Most will be minor — scuffed paint, stiff doors, incomplete grouting. Significant items like water ingress around windows, unlevel floors, or incomplete electrical installations must be resolved before you take possession, not promised as future remediation.

Finishing Costs: The Budget Trap Most Buyers Fall Into

New builds are delivered with a basic specification — walls ready for painting, floors covered in screeding or basic flooring, kitchens and bathrooms fitted to developer standard. The gap between "developer standard" and "how you want to actually live in it" often runs to €10,000 to €30,000 in the first year.

Experienced buyers prioritize infrastructure items that are expensive to retrofit later:

• Additional electrical sockets and charging points for EVs or solar
• Upgraded kitchen units or layout before completion (cheaper negotiated pre-build)
• Mechanical ventilation ducting for heat recovery systems
• Zoned heating manifolds if using underfloor heating

Cosmetic items — flooring upgrades, painting, furniture, blinds — can be added gradually as finances allow. Infrastructure cannot.
