Cardsave have joined forces with Consortium (UK) Ltd who specialise in providing highly competitive rates for business line rentals and telephone call charges. Easy transfer, only one bill, and there's no need to change your current equipment or phone numbers to take advantage of these immediate savings.
What's more, although Consortium will provide your bill and first line of support you will still be directly connected to the BT network and therefore they will continue to maintain your lines together with any special services which you may subscribe to.
