The top companies supplying to UK government with the same SIC code (26110 - Manufacture of electronic components) as IQE SILICON COMPOUNDS LIMITED are:

• The council hasnt published the data
• We havent found or been able to process the councils data
• The company is part of a group of companies and another company in the group is liable for business rates
• The registered office may be a residential address which does not have a commercial designation. If the business is run from home then it won't be a commercial property and hence won't be liable for business rates.
• Serviced offices are increasingly popular and therefore a business may not be paying business rates directly - the building owner is and this is incorporated in the office rental charge.
