With minnow housebuilders/builders it can go either way.
They could be good and really customer focus because they are small and able to do it, keen to build a reputation, OR they could be totally indifferent and build a rubbish new home.
You should follow the advice on the main website especially
1) Never use the builder's suggested solicitor.
2) Get EVEYTHING in writing
3) Do not buy if an NHBC warranty is not available.
4) Get the home independently professionally inspected before legal completion.
