Why do prices differ in Belfast?
Northern Ireland labour rates typically sit 10-15% below the GB average, and some GB compliance rules apply differently or arrived later.
Belfast's red-brick terraces and parlour houses are compact and conventional to work on, and labour rates sit below the GB average. The practical difference is regulatory: NI tenancy and certification rules have their own timetable, and some GB schemes and grants simply don't apply.
