150 hours?
Jump on me if I'm wrong but don't you have a limited time to complete the 150 hour course?
Also, a guy doing his CPL at the same school as me was in a very similar position. The CFI wouldn't recognise any of his hours until he sighted his training records.
The link above sets that out quite clearly in 2.8.7 of the Day VFR document what you need to do if you change schools.
Can anyone shed some light on the time frame for completion?
