Double glazing installers in Welwyn Garden City: Homeowners vs renters

For homeowners

If you own your home, you’re responsible for arranging and paying for double glazing work. Most replacements fall under permitted development, but if your property is listed or in a conservation area, you may need planning approval. Installers should provide compliance certificates (such as FENSA) once the work is complete.

For renters

Tenants are not usually responsible for replacing windows. If you’re experiencing draughts, condensation or damaged glazing, report the issue to your landlord or letting agent. They are legally responsible for ensuring windows are safe, secure and energy efficient.
