Had British Gas in to quote for installation of gas central heating
today. Nice simple job, so they said, 2 bed house, combi boiler etc
etc. 4,400 quid.

Took a look at the first online place i could find selling the precise
model of boiler they itemised on the quote, 578 quid plus vat,
compared to 1911 plus vat from BG. Utterly, utterly remarkable.

Is this sort of mark up usual for BG?
