No it can't be right.

With domestic NG gas installations, you need to take into account the overall use of the house, eg, gas fire & cooker. (By the book)The gas enginneer should not allow a 1mb drop from the meter to the appliance, sounds like the enginneer is correct, however I dont know how far the 28mm pipe would need to be run for without know the distances and the KWs of the other appliances. In gas collage they teach a presure drop chart, that I dont have time to tell you now, but the engineer should show you these calulations.
