NOTE - The HHSRS assessment for Crowding and Space differs from other Hazards.
As with all Hazards, the dwelling is first assessed disregarding the current occupiers.
In most cases, this will mean that the dwelling will be satisfactory (ie, average) having
regard to the space available for sleeping, living and recreation. A supplemental
stage is necessary taking into account the current occupiers to determine whether the
dwelling is crowded - ie, is there a mis-match between the size of the household and
the dwelling. It is this Adjusted Hazard Score which should be taken into account in
deciding whether action is necessary.

DESCRIPTION OF HAZARDS
Dwelling: 1870 mid-terraced house
Background: This is a late 19th century mid terraced house with a two-storey back addition. The
dwelling comprises two bedrooms and a combined bathroom/wc compartment to the first floor, and
one 'knocked through' living room and a kitchen to the ground floor. The original outside wc
compartment is still available. There is a small rear yard contained by walls, with rear access via a
gate leading to a back lane.

girls aged 13 and 11 and a boy aged 9 years.

RATING
For the purposes of the Rating System, the current occupation is disregarded in the
assessment of the dwelling. The dwelling provides adequate sleeping, living and
recreational space for up to 4 persons (irrespective of age). On this basis, the dwelling is
satisfactory. However, there is a mis-match between the current occupying household
and the house - on which see below.

Unlike other hazards, with lack of space and overcrowing, the severity of the risk will
depend on the number of current occupants in the dwelling. In this case, the household
comprises 5 persons and this dwelling is not big enough for such a household. This
increases the likelihood of a harmful occurence, but not the spread of health outcomes,
giving a hazard score of 365 and a rating of band E.
