Slow Like Query

i want to have a like search in the following query.

SELECT DISTINCT TOP 200 a.AccountID,
a.AccountNumber,
c.CLI,
con.SurName,
addr.Address1 [Account Address],
addr.Postcode as [Account Postcode],
atp.Name AS Type,
cs.Code AS Status
FROM account_t a
INNER JOIN customer_t cust on a.customerID = cust.CustomerID
INNER JOIN AccountType_T atp on cust.AccountTypeID = atp.AccountTypeID
INNER JOIN CustomerStatus_T cs ON a.CustomerStatusID = cs.CustomerStatusID
INNER JOIN Contacts_T con on cust.MasterContactID = con.ContactID
INNER JOIN Address_T addr ON cust.MasterAddressID = addr.AddressID
LEFT OUTER JOINCLI_T c ON a.AccountID = c.AccountID
WHERE (c.CLI LIKE @CLI + '%')
AND (con.SurName LIKE @Surname + '%')
AND (addr.Address1 LIKE @Address + '%')
AND (REPLACE(addr.Postcode, ' ', '') LIKE @Postcode + '%')
AND c.DateArchived IS NULL

here all fields @CLI, @Surname, @Address, @Postcode are varhcar types...which is making this query very slow...is there any suggestion to improve this query?

thanks in advance
