Actually 30 June is Bovis financial half-year figures date nearly ad bad as year end dates!
1) Do not be pressured into legally completing if the home isn't finished or ready for occupation.
If there are workman still working it isn't finished!
2) The NHBC will need to carry out a final CML inspection before you can legally complete, however this does not guarantee or rule out the possibility that there will be lots of snags and/or incomplete work.
3) Once Bovis (and most other house builders for that matter) have all the money, they are disinclined to return to carry out snagging whatever they may tell you before legal completion.
4) Bovis have possibly the WORST record in my experience for customer service after care. If its not 100% when you move in, it is likely to remain so.
5) Bovis are required to give you 14 days notice of legal completion. (10 working days)
Obviously, if they do this before the home is 100% finished and it isn't on completion day, then you should not legally complete.
My advice is stick to your guns, don't move in until all your inspector's snaglist has been rectified and your home reinspected. He is quite right by the way saying he cannot snag until all the work is complete. He cant check what isn't there, or isn't finished. If I were you I would get Bovis to pay his fees!
Bovis are Britain's worst housebuilder (for quality and service) in my opinion! Rated 3 stars for a reason!
