Derek unless all you compete on Is price then knowing your compition is helpfull,
An example is a local company to me who I often quote against, I know he works alone, I always mention that I work with my son so will happily move and replace all the furniture...... He won't. although I am slightly more expensive I usually get the job
Another example is another hull company. they are a great company and a lovely couple own It, but I know they have a big office with staff, I mention to customers that this office and all their staff needs to be paid for, and who really foots the bill? the customer.... We work from home so can offer a more competitive price
Knowing other companies weakness is a valuable tool when quoting against them
