Frequently asked questions
Does 21 Degrees Nottingham | Formerly Green Building Renewables offer free site surveys before quoting?
Most reputable UK installers — including most Nottingham-area firms — offer a free desktop survey followed by a paid or no-cost roof inspection. 21 Degrees Nottingham | Formerly Green Building Renewables's specific policy isn't published on EnergyRanked; ask when you make initial contact (their website 21degrees.com is a useful starting point). A red flag would be any installer quoting without ever physically seeing the roof or property.
Are there other solar installers in Nottingham I should compare?
Yes — three quotes is the UK standard.

UK solar workmanship warranties commonly run 5–10 years; panel performance warranties 25 years; inverter warranties 5–12 years.

Does 21 Degrees Nottingham | Formerly Green Building Renewables cover areas outside Nottingham?
