De Vere Venues has confirmed that Altitude London will no longer be represented under the De Vere Venues portfolio, following a change in management contract.
Altitude London has moved to an in-house management team.
The contract between De Vere Venues and Altitude was agreed in April 2013.
The move to in-house management at Altitude will see a change in emphasis at the venue to a more "boutique style".
A spokesperson for International Franchise Services Group, the owner of Altitude London premises, said: "The time feels right to take management back in-house for Altitude London. All the spaces are very individual and have a real boutique feel to them; our in-house team will be seeking to develop to the conference and B2B events market."
Tony Dangerfield, De Vere Venues CEO commented: "The De Vere Venues portfolio is diverse and dynamic with each venue operating under ownership, franchise agreement or management contract and in our fast-paced industry it is standard practice that contracts be reviewed on a regular basis.
"De Vere Venues has enjoyed a positive working relationship with Altitude London and we wish them every success in the future."
He added: "We look forward to announcing new partnerships in due course as part of our on-going development strategy.’’
