We built our hosting around exactly these requirements.
Registration numbers and accreditations are the first thing customers look for. Fast hosting means they see them before they bounce.
Send COCs and quotes from your own domain — it is what commercial clients and insurers expect to see.
Your site and its enquiry history are backed up every day and restorable yourself, at no extra cost.
Contact and quote request forms are encrypted, which matters when customers send addresses and details.
