Belfast and Cardiff cost about the same month to month once rent and everyday spending are combined.
Both run on local + English at work, so the edge comes down to your sector. Belfast: Cyber security & fintech, Software & professional services, Aerospace & advanced manufacturing. Cardiff: Insurance & financial services, Broadcasting, film & television, Government & the public sector.
Belfast feels like “A UK city in a different legal jurisdiction — Irish citizens need no permission at all, your landlord usually pays the rates, and nobody gets a water bill”, while Cardiffis “A capital with its own parliament, its own property tax and free prescriptions — where you sign an occupation contract, not a tenancy”. Climate is a real differentiator: Belfast — temperate maritime and very mild, ringed by hills on three sides and a sea lough on the fourth — rain on more days than almost any large uk city, snow rare at sea level, and summer highs that seldom pass 20 °c. Cardiff — temperate maritime and one of the wetter big cities in britain — mild and windy off the bristol channel, with snow rare at sea level and the beacons white an hour behind you.
