Window fitters in Harrow: Homeowners vs renters

Homeowners:

If you own your property, you’re responsible for window upgrades. If you're changing the style or layout, check if you need planning permission, particularly in conservation areas or listed buildings.

Always ensure your installer provides a FENSA certificate for replacement work. It proves compliance and can help with future property sales.

Renters:

If you rent your home and have issues with your windows (draughts, condensation, broken locks), your landlord is responsible for repairs or replacements.

Not sure how to raise it? Start by reporting the issue in writing and include photos. If you don’t hear back, your local council’s housing department can offer support.
