Fire alarm battery change

Turnpike Lane, Greater London
4th Jan 2026
Our alarm needs changing batteries but we've no step ladder and it's in a very awkward position on the upstairs landing above the stairs and the ceiling is high. Not entirely sure what batteries needed as first time we've changed it. Would be great to get it sorted and have correct batteries refitted safely, or if it just needs a reset - for that to be done. Quick help would be great as we've had a neighbour mention it.
