What can change a real Belfast quote?

  • Bathroom size and finish level
  • Moving toilet, bath, shower or basin positions
  • Wall and floor tiling area
  • Bath, shower and enclosure specification
  • First- and second-fix plumbing
  • Electrical work and ventilation
  • Underfloor heating, plastering and decoration

Local planning considerations

Northern Ireland has different policy and grant arrangements from Great Britain, so scheme-specific calculator assumptions should be checked carefully.

  • Northern Ireland regulations, approvals and support schemes should be checked independently from England, Wales and Scotland guidance.
  • Regional material supply, specialist-trade availability and travel can affect individual quotes beyond the broad model factor.
  • For major refurbishment, keep surveys, remedial work and compliance costs separate from visible finish upgrades.

How the regional model works

The 0.89× factor places this planning estimate 11% below the national planning baseline. We keep that modelling assumption separate from the dated national benchmark so users can see which part comes from an external source and which part is UK Home Costs modelling.
