If I’ve done my job correctly, you will already have heard that we have changed our business name from Fozmula Limited to Rochester Sensors UK Limited. If this news has come as a surprise, then please accept my apologies. If you’re interested in reading more about our brand story, including the meaning behind our new logo, visit our name change statement here.

For your records and admin purposes, the only changes are to our business name, logo, email addresses and our website domain. Our postal address remains the same, as does our company registration number, bank account numbers, EORI numbers, DUNS number, and Tax / VAT IDs.
