Underfloor heating in Cardiff: Homeowners vs renters

Homeowners

If you own your property, you’re responsible for installation, servicing, and repairs. Keep any certificates provided by your installer for insurance and resale purposes.

Renters

Typically, landlords are responsible for heating systems. If you need repairs or servicing, report the issue to your landlord or letting agent before booking work. You may still arrange underfloor heating maintenance for smaller fixes, but always check your tenancy agreement first.
