Once you have committed to buying a home (at exchange of contracts) the house builder will have agreed to build the home and keep you informed of progress. If you are unhappy about any delays in construction, you must speak to the house builder. Your solicitor/conveyancer will be able to advise on the house builder’s contractual responsibilities before you agree to the sale. You should check with your house builder that the funding will be available on the date you expect to complete your purchase.
