Whole-property planning context
What can change a real Cardiff quote?
- Electric or wet system
- Heated floor area
- New build or retrofit
- Insulation level
- Screed and floor build-up
- Controls and heating source
Local planning considerations
For grants and energy schemes, verify the current Wales-specific eligibility rules before relying on any support assumption.
- Use Wales-specific planning, building-control and energy-scheme information where the rules differ from England.
- Terraced or constrained urban properties can add access, waste and scaffold costs that are not captured by the regional factor.
- Drainage, roof and external-work scopes should be based on the property condition rather than a generic city assumption.
How the regional model works
The live underfloor-heating calculator applies 22% of the broad Wales regional difference because UFH includes both nationally priced system components and local installation labour. The resulting Cardiff factor is 0.980× and is applied to the current system-specific cost-per-m² benchmarks.

How much does underfloor heating cost in Cardiff in 2026?
Current UK installation rates run from £50–£75 per m² for electric new-build systems to £95–£110 per m² for wet retrofit systems. Applying the live calculator's moderated regional factor gives £49–£74 per m² for electric new build and £93–£108 per m² for wet retrofit in Cardiff.
How much is 60m² of wet underfloor heating in a Cardiff renovation?
The current national wet-retrofit benchmark is £95–£110 per m². For 60m², the live calculator's regional model gives a planning range of about £5,600–£6,450.
Is electric or wet underfloor heating cheaper to install?
Electric systems usually cost less upfront. Current UK rates are £50–£75 per m² in new builds and £60–£85 in renovations, compared with £85–£100 and £95–£110 respectively for wet systems.
What can make underfloor heating more expensive?
Retrofit floor build-up, insulation, screed, floor-height changes, manifolds, controls, difficult layouts, electrical work and the existing heat source can all increase the final cost.
