Dodgy old boiler with no current in madam's house (8)
I believe the answer is:
bordello
'madam's house' is the definition.
(I've seen this before)
'dodgy old boiler with no current' is the wordplay.
'dodgy' indicates an anagram (a dodgy or wrong order of the letters).
'with no' suggests deleting specific letters.
'current' becomes 'I' (symbol for electric current).
'old'+'boiler'='oldboiler'
'oldboiler' with 'i' taken out is 'oldboler'.
'oldboler' anagrammed gives 'BORDELLO'.
'in' acts as a link.
(Other definitions for bordello that I've seen before include "House of ill-repute" , "Brothel" , "12 across (anag)" , "House of ill repute" , "Where one pays for the other" .)
