COVID-19 & Consultations

To reassure you London Bridge Hospital  (HCA Group) has been providing regular updates from Dr. Cliff Bucknall, Chief Medical Officer for HCA on a regular basis to staff and consultants.

The London Bridge Hospital has taken significant steps to reduce the risk of introducing COVID-!9 virus into the hospital or the outpatient environment.

In summary, the hospital has instigated:

  • All patients/relatives are screened at reception before entering the hospital

  • All patients booked for admission are screened by telephone and surgery delayed by 14 days if they have been to a tier 1&2 country (regardless of contact) or if they have been in contact with someone in the UK

  • All patients booking for OP appts with respiratory symptoms are having telephone appts first with the consultant (all general physicians and respiratory docs have been called to ensure they are aware).

  • No NHS transfer or international patient admission is occurring without a COVID negative test within the last 48 hours.

  • The Urgent Care Centre service at London Bridge Hospital has been temporarily suspended to try to minimize the risk of a COVID-19 patient being admitted or transferring the virus to both staff and patients.

However, in line with reducing traveling and contact unless necessary, we are aware that some patients may still need a consultation to reassure or to commence urgent investigations.


At The London Colorectal Clinic, we are now able to perform a telephone or web conference consultation on Monday am 09:00 - 12:00 GMT or Wednesday from 18:00-20:00 GMT. Other consultation times may be available on a discussion.


The 15-30min telephone or web consultations are £175 for self-paying patients. If you need a follow-up outpatient consultation for the physical examination is required then we will take into consideration the fee already paid. For example, a follow-up consultation will incur an additional consultation fee of £25 + £15 room hire fees. Please note that depending on what equipment is used for your examination there may be additional fees from the hospital. 


If you have private health insurance we encourage you to discuss with them if they will cover the cost of your telephone or web conference consultation. Historically insurance companies have never been too keen on reimbursing practitioners for telephone or virtual consultation with web conferencing facilities but with the current situation of the need to reduce physical contacts this situation is set to change.
