Two cities, two currencies, one island: the unique Belfast-Dublin comparison
Belfast and Dublin sit 100 miles apart on the same island, connected by a 2-hour train ride or 1-hour 45-minute drive. But they operate in different currencies, under different tax systems, and in markets that have diverged significantly in salary level and cost of living over the past decade. Understanding how they compare requires converting both to comparable terms rather than reading headline numbers in different currencies.
Belfast is part of the United Kingdom (Northern Ireland), uses GBP, and its tech salaries are benchmarked against the UK market. Dublin uses EUR, and its salaries are driven upward by the concentration of US Big Tech EMEA operations. The headline gap looks large: a Belfast Senior Software Engineer earns £72,000 (~€84,000 at mid-2026 rates) versus €110,000 in Dublin. But once you adjust for housing costs, tax differences, and the purchasing power of each currency in each city, the picture changes substantially.
Salary comparison: Belfast (GBP) vs Dublin (EUR) (2026)
Belfast in GBP and approximate EUR equivalent · Dublin in EUR · tech roles · GBP/EUR exchange rate ~1.17
| Role | 🇬🇧 Belfast (GBP) | Belfast (~EUR) | 🇮🇪 Dublin (EUR) |
|---|---|---|---|
| Senior Software Engineer | £72K | ~€84K | €110K |
| Engineering Manager | £85K | ~€99K | €128K |
| Data / AI Engineer | £78K | ~€91K | €120K |
| Cloud / Platform Engineer | £74K | ~€86K | €115K |
| Cybersecurity Engineer | £72K | ~€84K | €108K |
| Mid-level Software Engineer | £55K | ~€64K | €82K |
Housing: Belfast is dramatically cheaper than Dublin
Belfast city centre one-bed rents average £800–£1,100 (€940–€1,290 at current rates) in mid-2026. Dublin averages €2,200–€2,800. The midpoint gap in EUR-equivalent terms is around €1,400 per month. That is €16,800 per year: a very large portion of the Dublin salary premium recovered in housing alone.
Senior Software Engineer: monthly financial snapshot (converted to EUR)
After tax (UK rates for Belfast, Irish rates for Dublin), rent, and estimated core costs · monthly · 2026
| City | Monthly net (EUR equiv.) | Est. rent | Other costs | Monthly headroom |
|---|---|---|---|---|
| Belfast (£72K / ~€84K) | ~€4,520 | ~€1,100 | ~€900 | ~€2,520 |
| Dublin (€110K) | €6,380 | €2,500 | €1,400 | €2,480 |
The comparison reveals that monthly headroom is nearly identical once housing is accounted for (€2,520 Belfast vs €2,480 Dublin). Despite earning €26,000 less gross per year in EUR-equivalent terms, a Belfast engineer ends up with comparable disposable income each month. The dramatic housing cost difference is almost entirely responsible for closing what looks like an unbridgeable salary gap.
Belfast's tech market: fintech, cybersecurity and cross-border employers
Belfast has developed a genuine fintech and cybersecurity cluster over the past decade, partly due to its lower cost base attracting firms that needed European-facing tech talent without Dublin's costs. Citi runs its largest European technology centre in Belfast. Baker McKenzie, Allen and Overy, and other global law firms have established significant legal technology operations here. Allstate Insurance runs a major analytics and engineering hub. FinTrU, Kainos, and Concentrix have built substantial engineering operations that draw from Queen's University Belfast and Ulster University.
Northern Ireland's post-Brexit position is also worth noting: as the only UK region with continued access to the EU single market for goods under the Windsor Framework, Belfast has attracted some investment from firms wanting a UK-regulated but EU-market-adjacent engineering presence.
Typical rent (1-bed, city centre)
£800–£1,100 (€940–€1,290)
Best fit for
Legal tech, fintech operations, cybersecurity, and engineers who want dual-market career optionality (UK and Ireland).
The dual-market career advantage: working in Belfast, accessible to Dublin
One factor that salary comparisons cannot fully capture is the career optionality that Belfast's proximity to Dublin creates. Belfast is 100 miles and a 2-hour train ride from Dublin. Engineers based in Belfast can attend Dublin interviews, maintain Dublin-market professional networks, and transition to Dublin employers when career objectives or salary expectations require it. The two cities are far enough apart to have distinct labour markets and cost of living, but close enough that crossing between them is practically feasible.
This means a Belfast engineer is not choosing between two closed markets. They are choosing a lower-cost base from which Dublin's higher salary market remains accessible when they want it. For engineers in the early-to-mid career stage who want to build savings quickly and buy property, Belfast's lower housing costs combined with Dublin-market career accessibility may be the most financially rational combination available on the island.

Belfast contractors: UK IR35 rules with cross-border optionality
Belfast contractors operate under UK IR35 rules, not Irish contractor regulations. Outside IR35 contracts draw on national UK day rates: Senior Software Engineers typically command £450–£600/day regardless of whether the contract is London, Manchester, or Belfast-based. The key difference is cost of living: Belfast's lower rent and expenses mean a given day rate retains more as real disposable income than in London or Manchester.
A Belfast contractor earning £500/day (approximately €585/day at mid-2026 rates) bills at near-Dublin equivalent levels in EUR terms, while living in a city where rents run around 60% lower than Dublin. Citi, Allstate, and FinTrU have meaningful outside IR35 and statement-of-work demand in Belfast for financial services technology programmes.
Cross-border arrangements (Belfast residents contracting for Republic of Ireland clients) introduce significant complexity. Engaging as a UK limited company for Irish clients may trigger Irish withholding tax obligations and Revenue scrutiny. Dublin-facing hybrid roles for Belfast engineers are increasingly common but are usually structured as employment rather than pure contractor arrangements to avoid this.

Frequently asked questions
Is Belfast a good city for software engineers?
Yes, particularly for fintech operations, legal tech, and cybersecurity. Citi runs its largest European technology centre in Belfast. Kainos (Belfast-founded, LSE-listed) employs 2,500+ engineers. Allen and Overy, Baker McKenzie, and Allstate Insurance run major tech operations. Belfast is less diverse than Dublin but has genuine depth in its specialist areas.
How much do software engineers earn in Belfast compared to Dublin?
Belfast Senior Software Engineers earn around £72,000 (approximately €84,000 at mid-2026 exchange rates). Dublin Senior Software Engineers earn €110,000. After converting currencies and adjusting for dramatically lower Belfast rents (€940–€1,290 versus Dublin's €2,200–€2,800), monthly disposable income is nearly identical between the two cities.
Do Belfast salaries use GBP or EUR?
GBP. Belfast is in Northern Ireland, part of the United Kingdom, so salaries are quoted, paid, and taxed in GBP under the UK PAYE system (income tax and National Insurance). Dublin salaries are in EUR under the Irish system (income tax, USC, PRSI). When comparing the two cities, you need to convert currencies to make a meaningful comparison.
Can I commute from Belfast to Dublin for work?
A daily commute is challenging at roughly 2 hours each way by train. However, hybrid arrangements of 2–3 days per week in Dublin are practical and are increasingly common for engineers who want Dublin-facing roles while living in Belfast. Some Belfast engineers maintain Dublin hybrid roles, effectively accessing Dublin salary levels while housing in Belfast at around half the cost.
What are the best tech employers in Belfast?
Citi (largest European technology centre), Kainos (Belfast-founded digital services firm), Allstate Insurance (analytics and engineering), FinTrU (fintech compliance tech), and global law firms Allen and Overy and Baker McKenzie for legal tech. Queen's University Belfast and Ulster University feed a steady graduate pipeline into these employers.
