Register a Company

I would be gratefully obliged if you could possibly advise me as to whether or not I should register my company at present, I have a new business with an equal partner, we have been trading for approximately 10 months as a cleaning company and currently have a number of domestic customers. The turnover is not substantial at present but we are in the process of applying for tenders to generate additional revenue.

My question is; would a lack of information available publically about the business make any difference to other companies researching mine and would we actually benefit at present from registration? Any advice gratefully received, as this appears to be confusing for me at present.
