UK Mortgages for British Expats in Ireland

Who this page is for

If you are a British national living and working in Ireland and you want a UK mortgage, this page is for you. Common situations we see:

• A British national working in financial services in Dublin's IFSC.
• A British national working in tech for one of the major Dublin-based multinationals (Google, Meta, Microsoft, LinkedIn, Stripe, and similar).
• A British national working in pharma or medical devices, often in Cork, Galway, or Dublin.
• A British national in a cross-border role between Northern Ireland and the Republic.
• A British national who relocated to Dublin post-Brexit for tax or career reasons and is now looking at UK property.
• A British national married to an Irish citizen and living in Ireland but maintaining UK ties.

Ireland sits in a unique position relative to the UK. The two markets are intertwined, the Common Travel Area allows free movement, and many lenders are comfortable with Ireland-resident British applicants.

What UK lenders think of Ireland

Ireland is one of the most lender-friendly countries in the expat pool. Around 12-15 expat lenders consider Ireland-resident British nationals. Several mainstream UK lenders treat Irish-resident British applicants on near-resident terms because of the close market relationship and Common Travel Area.

Where Ireland is straightforward:

• Stable euro economy, mature banking, transparent tax reporting.
• Direct flight access to the UK and physical proximity.
• British applicants typically retain UK ties (NI number, often a UK bank account).

Where Ireland needs careful handling:

• The Common Travel Area can blur residency definitions. Some lenders ask careful questions about where you actually live and pay tax.
• Some lenders want to see formal Irish tax residency status before treating the case as a non-UK resident expat.

How euro income is treated

Euro is hard currency. The standard 20 percent haircut applies at most lenders. A handful of specialist lenders apply no haircut.

Ireland has very high marginal tax rates (up to 52 percent including USC and PRSI). Some lenders look at gross income, others at net. For high earners on Irish PAYE, the difference can swing borrowing power significantly. Try the expat mortgage calculator to see what each scenario means for your income.

Deposit and rates

Deposits for British expats in Ireland typically sit at 20-30 percent. Ireland often accesses lower deposit floors than other expat markets because of the close market relationship. Some lenders go to 80 percent LTV for Irish-resident British applicants on standard PAYE income.

Expat rates from Ireland are typically 0.2 to 0.5 percent above the equivalent UK-resident product, the narrowest premium of any expat market.

The Dublin tech employer angle

A large share of British expats in Ireland work in the Dublin tech sector. UK lenders are familiar with the major employers (Google, Meta, Microsoft, LinkedIn, Stripe, Intercom, and others) and treat their income similarly to UK tech employer income.

Stock-based compensation (RSUs, ESPPs) is common in Dublin tech roles. Some lenders include it in affordability with a discount; others exclude it entirely. Lender selection matters where stock comp is a meaningful portion of total compensation.

Common situations from Ireland

Dublin tech employee buying first UK property. Common case. Strong employer, stable PAYE income, deposit accumulated. Deposits 20-25 percent, competitive rates.

Cross-border worker (Northern Ireland and Republic). A British national living in NI and working in the Republic, or vice versa. Lender selection critical to handle the residency picture cleanly.

Buy-to-let from Ireland. Common for professionals on strong euro PAYE income. ICR thresholds standard.

Returning to the UK from Ireland. Often the simplest expat return because of the Common Travel Area and the market closeness. Apply 2-3 months before the move.

Joint mortgage with UK partner. A British expat in Ireland buying jointly with a UK-resident partner. Treated as a joint expat-resident case with specific lender appetite.
