Having read up a bit tonight the last series was reworked to reflect CBBC now being aimed at 6-12 year olds, moving to The Grange, a multi-media site where Year 7s like to hang out and were frequently joined by Year 6's from a local primary. It basically only existed as they were contracted to produce it and though Phil Redmond signed it off he wanted to pull the plug as the show couldn't fulfil it's original premise under these new guidelines.
Phil Redmond is very good at completely absolving himself of all responsibility for his programmes when they get axed, he did that with Brookie, blaming everyone and everything for the falling ratings apart from the programme itself. And when he took over Grange Hill, he clearly said it was going to be aimed at 8 to 11 year olds, and that it was going to feature "a bit more fun and a bit more comedy" -

Seem to recall reading somewhere (may have been on here) they knew it was going to be the final series.
In fact wasn't it one of those "we'll air two or three episodes on CBBC on BBC One and air the rest of the series on the CBBC Channel" things?
Yes, it was promoted as the final series. It was first shown on the CBBC Channel but the entire series was shown on BBC1, albeit they took their time to complete it - it was once a week on Mondays, and with breaks for Bank Holidays it took about six months to finish.
Did they know the show had been axed when they reverted to the original music for the last series.
Like was said above, I wonder what kids thought when the music suddenly completely changed to this unheard of tune.
The 1990 theme tune was an "unheard of tune" when they introduced it. It's just another theme tune.
