Don't think it is standard.
Our bill from solicitor for purchase had the following items on it:
Stamp duty - alarmingly large amount
Stamp duty admin fee - £35.25
HM Land Registry fee - £420
Solicitors costs re purchase and mortgage - £1,750
Bank TT fees - £29.38
Search fees - £213.62.
We also paid £399 to the mortgage company as an arrangement fee. Could this be the mortgage companies estimation of your solicitors costs?
its not a high loan to value fee, is it? If your mortgage amount is more than 75% of the property value, it could be. It could also be an approximation of your own legal costs incurred in the move - mortgages these days have to include all possible costs. Does it say if this is to be paid to the solicitor or added onto the loan?
