Double glazing installers in Harrow: 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. See our guide to preparing for double glazing installation for what to expect. Installers registered with a competent person scheme, such as FENSA, can self-certify the work meets Building Regulations. Ask your installer whether this applies to your job.

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.
