Depending upon the sample frame you are targeting, and the type of information you are looking to collect, you may well find that someone else is already conducting a market research study that you can add a few questions to. Many are ongoing studies that continually collate data and report their results weekly, monthly or quarterly.
There are many Omnibus studies of this nature being conducted in the UK or wider afield at any one time. Frequently they are targeted at specific consumer groups, certain areas of the business communities or educational establishments.
This type of research can cost you less than undertaking your own fully blown market research project, however you may need to participate knowing that you are unlikely to find a study that exactly matches your requirement, and you may need to be a little selective about the specific results you use.
