DESCRIPTION OF HAZARDS

Dwelling:

Pre 1920 two-storey, mid terraced, house

Background: This is a traditionally constructed house of pennant stone walls under a clay tiled roof. It is a

good state of repair and free from any significant dampness. It comprises two reception rooms, a kitchen and

bathroom on the ground floor and three bedrooms on the first floor. All windows are single glazed (the

majority are double hung, sliding sashes) but are in a good repair and not excessively draughty. The loft

space is insulated with 200mm of glass fibre quilt. Heating is provided to all rooms (with the exception of the

kitchen) and in the ground floor hallway by electric night storage heating run off an economy tariff. The

storage heaters are around 12 years old and in good working order but do not have an additional "convector

boost" or dual heat facility. The current occupant has identified that they produce little heat in the evenings

and none at night even if they are set to low output during the day.

Justification: The original single glazed windows, although in good repair, will still allow some draughts and

heat loss. On the positive side, the property is mid-terraced, and provided with a reasonable standard of loft

insulation. Althouh there is heating provision in all of the main spaces used as habitable rooms, the charge

period asociated with economy tariffs and high static heat losses associated with these heaters means that

there will be inadequate heating in the evenings and early mornings. At these times the house has a higher

likelihood than average of becoming unhealthily cold in winter without the use of supplementary heating. The

likelihood of an occurrence resulting in harm to an elderly occupier over a 12 month period is increased from

the national average.

Justification: Converting to a split tariff with a late afternoon top up charge, could result in the heating

system providing heat in the evening period, but such tariffs are frequently unavailable. Thus a satisfactory

reduction in the likelihood of harm would only be achieved by installation of full gas central heating system

with programmable controls. Secondary glazing would further reduce heat losses and the likelihood of harm

to well below the national average.

Justification: There is nothing to suggest that the harm outcomes will differ from the national averages
