We have a four bed house which we let out as a shared house to 4 people. This is now covered by additional licensing and we need to register it. It has a mains fed alarm system but does it also need manual call points? Many thanks.

Because it is a HMO under additional licensing the Housing Act is the principal legislation the local council is the enforcing authority but most enforcing authorities accepted the Guidance on fire safety provisions for certain types of existing housing as the national guidance. You have not provide sufficient information but I would say the fire alarm required is a grade A or D depending on how many floors, which to my knowledge there is no facility to connect a manual call box on a grade D but there is on a grade A. You need to study the attached guide to see which type of fire alarm you have and require according to the guide.
