It is not uncommon for a company to be incorporated with errors. Often, a lot of these errors are easily rectified by filing various forms with Companies House.
However, information regarding the majority of changes will be permanently displayed in the company history, information that is publicly available.
For example, a company may be formed with a typing error in the name. Fixing this could be as simple as applying for a name change, however a typing error in the company history may not appeal to any potential investors or clients in the future. Dissolving this company and forming a brand new entity could be the better option in the long term.
