Barratts have already said that they will not move on price so I'll see what extras they throw in to "Incentivise the sale". Assuming of course they come up with a sensible valuation on mine.
I will also be engaging a Snagging company. I could do it myself but having the builder know a professional outfit is doing it will put pressure on them (I hope).
You are doing everything right.
Appointed your own solicitor. Barratt cannot force you to use theirs (Consumer Code for Home Builders requirement 2.5)
You will use a professional snagging company and tell barratt. Please do not legally complete unless the snags are done beforehand.
As pointed out, once the trades leave the site, you are in the hands of customer care and subcontractors and this is when problems can arise getting issues put right.
You want a deal. The sales advisors can agree what thye call negotiables" usually up to 5% of the asking price. Above this level it needs regional office approval. This can only be done at reservation not after.
The only thing you may be doing wrong is buying a house near the house builder's year-end.
Barratt's year end is 30 June so any home completed is likely to be rushed.
You are quite correct, Barratt do seem to have improved the building quality of their new homes.
However most complaints appear to be with regard to misleading information at sales and reservation.
Get everything in writing and be aware of the Consumer Code for Home Builders.
Please spend some time reading my website for more useful advice and tips too.
Have you checked the development in Ely for flood risk for example?
