Boiler engineers in Portsmouth: Homeowners vs Renters

Homeowners

You’re responsible for booking regular boiler servicing and arranging any repairs. Most warranties also require an annual boiler check, so keep those records safe. If you’re selling your home, up-to-date servicing history can be a real plus.

Renters
