Once you have a mortgage 'in principle', your lender will also want a 'mortgage valuation' to make sure that the the property you’re buying is worth the price you’re paying. If it is included as part of the Home Report they may be happy to use that one. However sometimes mortgage lenders prefer to arrange an independent valuation. If that is the case, a 'mortgage valuation' can typically cost between £150-£1,500 depending on the value of your property.
