By confirming the booking you acknowledge and confirm that you (the Hirer) have understood and agreed to comply with the terms and conditions contained below.

Our hire policy exists to ensure that the inhabitants of the spaces work in a safe and comfortable environment. We therefore ask visiting companies, or regular users of the space to ensure they adhere to the following:

  • Opening/Closing Times – The building is bookable between Monday to Saturday.
    • Day slots 10:00-18:00 – You’ll be able to enter the building when the door opens at approx 09:30 (unless there is an emergency). You will then need to vacate the room by 18:00 at the latest to allow for disinfecting before the evening groups to come in at 18:30. If you are on a long term day booking you will need to have moved all set/props costumes to the designated taped area shown to you on your first day.

COVID – 19:

  • Covid-19 Precautions – The Hirer must familiarise themselves with the Covid-19 procedures and must make sure all participants are fully informed of said procedures. Any non-compliance should be reported directly to a Wildcard member of staff. Government recommended face-masks must always be worn in all public areas of the building, however, we give permission for companies to remove their masks during rehearsal if all members of their group are comfortable with this. For best practice, Wildcard’s advice is to not share personal items such as chargers, bottles and stationery. The Hirer is responsible for checking on the daily health and well-being of the group. These are Wildcard’s independent safety procedures – however it is also the responsibility of the Hirer and participants to adhere to up-to-date advice and restrictions as provided by Public Health England. The Hirer must ensure the practice of regular hand-sanitiser usage, especially when entering and leaving both the rehearsal rooms and the building. The Hirer will vacate the premises no later than their hire time specifies, to ensure adequate time is given for staff to disinfect the property and enter/leave without cross-contamination. For details of the PHE’s Covid-19 policies, please visit:
  • Lateral Flow testing – Under guidance of our T&Cs it is the responsibility of the lead booker/Hirer/Stage Manager to keep up to date with the health and Covid status of their company before entering the building. We would ask that all creatives have provided evidence of a negative lateral flow or PCR to the lead booker before entering the building each session. During your stay, if someone tests positive the studios must be informed by emailing or speaking to a Wildcard member in the building. The creative who has tested positive may not return to the building until they have been isolated for 10 days — in accordance with the Government’s guidelines — and can provide a negative PCR result. Fully vaccinated company members who have come in contact with an individual who has tested positive will not be asked to self isolate but will have to continue providing negative lateral flow tests. This is in accordance with Current government guidelines but may be subject to change if updated information is advised by the NHS.
  • Cancellations due to changes in government regulations/lockdown
    • If the booking is cancelled because Wildcard has closed due to changes in government regulations or a national lockdown, Wildcard studios will consider the hire agreement to be ‘frustrated’ and will offer credit for future booking; a full or partial refund for the affected period will also be offered upon request; in which case, please email
    • If your booking can go ahead despite changes to government guidance but the show/project/performance or activity that related to your booking cannot, Wildcard studios will look into this and offer a full or partial refund upon request. You must provide the studios with the name, date and details of the cancelled activity. Evidence must be provided that the project has been asked not to go ahead due to changes in the lockdown law or government guidance. In which case, please email . Covid 19 consumer contracts, cancellation and refunds can be found here.

We are limited in our staff and would appreciate help in keeping the studios tidy for other users.
  • Noise – Wildcard Studios are a ‘found space’ and so not purpose built rehearsal rooms. Due to this we cannot permit any amplification of any kind in the rooms. If music / instruments / singing / recorded sound is used in any rooms and proves disturbing to others, we reserve the right to ask for the volume to be lowered, and in extreme circumstances, for the sound to be turned off completely. The rehearsal spaces in the building are often close together; please show courtesy to others in the premises by keeping noise to an acceptable level. Please make sure that you keep noise to a non-intrusive level after 6pm.

Any damage to the space or mess left as a result of your use will be invoiced to you, and will include the time and labour required to get the space back to standard.  The Hirer must inform Wildcard of any damage they or their colleagues have caused immediately — by phone, text or email — so that it can be repaired. A failure to inform Wildcard may result in all future bookings being cancelled and your payment retained.

The Hirer must complete a risk assessment for each space used. The first aid kit and accident book is kept at reception. Should a participant sustain an injury, please report it to reception. The Hirer must also comply with the requirements of Health and Safety at Work Act 1974 (and all future amendments thereto), in particular (but without limitation) the need to provide confirmation that all equipment used complies in all respects with required Codes of Practice (for example, that all electrical items have current PAT testing certificates, hazardous substances have appropriate COSHH documentation and that the entire activity has suitable Risk Assessment Records). If the Hirer has any queries in this respect, please contact Wildcard. The Hirer must not place any obstructions in entrances/exits, on stairs or in passages, or obstruct access to all places of work in any way.

  • Insurance – The Hirer acknowledges that the loss of any items left unattended is not covered by Wildcard’s insurance cover and so the responsibility of these items falls onto the Hirer. It is required that the Hirer should purchase their own Public Liability insurance.
  • Limitation of Liability – Neither party excludes or limits liability to the other party for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation nor where liability cannot be excluded or limited as a matter of law.
