Gas boiler installation in London: Homeowners vs renters

Homeowners:

If you own your home, you’re responsible for the boiler. That includes paying for replacement, servicing, and any repairs. If you're selling, it helps to have paperwork showing recent work and service history.

Renters:

If you rent, your landlord is responsible for boiler maintenance and replacement. If your boiler stops working or you notice issues, report it to them or your letting agent straight away. They should arrange for a Gas Safe registered tradesperson to fix or replace it.
