"Summary
Your Boiler is a 'G' rated boiler, this has very poor efficiency below
70%, in your case it's 75.1%."

Has Dribble had a hand in this site?

For the boiler I removed and replaced with a Grant boiler some years
ago, we had the amusing message: "Your boiler is unrated because it's
obsolete or very old." and "SAP Seasonal efficiency 70%".

If it wasn't rated, HTF do they know what its efficiency is?

Wouldn't admitting "we don't know what the efficiency is so we scored it
at the lowest level" have been more honest?
