As I understand it in a case like this the FSO will over rule the Equality Act. the reason being that the FSO is Criminal Law and the Equality Act is Civil Law. Criminal Law over rides Civil Law. There is also the issue of Penalties where the Act which has the more severe penalty overrules the Law with the lesser penalty. Again in this case under the Equality Act you can only be sued in the Civil Court whilst under the FSO you can be heavily fined and/or imprisoned.
The only issue which you would need to address is the question of being able to adapt the premises for non able bodied persons. Under the Equality Act you have the following duty.
The duty comprises the following three requirements.
(3) The first requirement is a requirement, where a provision, criterion or practice
of A?s puts a disabled person at a substantial disadvantage in relation to a
relevant matter in comparison with persons who are not disabled, to take such
steps as it is reasonable to have to take to avoid the disadvantage.
(4) The second requirement is a requirement, where a physical feature puts a
disabled person at a substantial disadvantage in relation to a relevant matter in
comparison with persons who are not disabled, to take such steps as it is
reasonable to have to take to avoid the disadvantage.
(5) The third requirement is a requirement, where a disabled person would, but
for the provision of an auxiliary aid, be put at a substantial disadvantage in
relation to a relevant matter in comparison with persons who are not disabled,
to take such steps as it is reasonable to have to take to provide the auxiliary aid.
The whole question comes down to 'what is reasonable?'
