Probably not. Most specialty consultants have sufficient knowledge and experience of general medicine to fulfil the ES role even if they are not currently engaged in the acute medical rota. However in some specialties there may be supervisors who do not do acute or general medicine, have not done so for some time, and do not feel comfortable acting as an ES for a GIM trainee. If you and your ES feel this is the case, you should discuss whether another consultant within the specialty could fulfil the role. If you need to look outside your department for a supervisor, trusts may have a local system for this (eg some acute physicians will take on this role) but typically it may need some mediation from your specialty TPD and / or the GIM TPD to ensure that other consultants are not overloaded with trainees requiring GIM supervision.
