COVID-19 Update

We just wanted to quickly touch base amidst the ongoing coronavirus epidemic to let you know that we will be operating as normal.

Several of Calcs-Online’s staff already had the capability to work from home, and we have now extended this to our whole team. In addition, since our phone system is internet-operated, this means that most of our staff are available on their extensions and can take calls as normal.

If you experience any difficulty getting through to us please drop us an email to and we will seek to put this right for you as soon as possible.
