Glass replacement in London: Homeowners vs renters

For homeowners

If you own your home, it’s your responsibility to arrange window glass replacement in London. Ensure your installer complies with building regulations (particularly around energy efficiency). Keep any receipts and certificates - you may need them if you sell your property.

For renters

If you’re renting, the responsibility depends on the cause. Landlords are typically responsible for replacing windows damaged by wear and tear. If damage was accidental, you may need to contribute. Always report the issue to your landlord or letting agent straight away, and get their approval before booking glass replacement services in London.

• Smashed windows after a break-in
