There are legal and administration costs involved in any mortgage process. Some lenders offer packages that as an incentive offer refunds on these fees as long as you use their own insurance and legal products. Be careful when checking your mortgage offer and make sure that the lender isn't offering you 'free' legal and administrative fees but in turn asking you to pay a higher interest rate in return.
Your solicitor will deal with the relevant bureaucratic processes and perform the conveyancing on your behalf such as local searches and the thorough checking of the details of the new mortgage deed in preparation for you to sign as well as dealing with the Land Registry.
