Background: This large three-storey Victorian house was converted in the 1950's to provide three self-

contained flats, one on each floor. The top floor flat comprises a large living room at the front and a bedroom at

the rear of the main part of the house. The bathroom, a separate w.c. and the kitchen/diner are located in the

long back addition. The loft has 100 mm of insulation.

Windows: Windows to the back addition kitchen, bathroom and w.c. compartment have been replaced with

louvred windows. All other windows are single glazed, double hung sashes.

Heating: The open fireplaces throughout the flat have been sealed. Radiant bar heaters fitted in the front

living/dining room, rear bedroom and in the dining area in the back addition.

RATING

With regard to its 9 inch solid brick walls, sash windows in the main part of the block

and generally low standard of loft insulation, the dwelling is typical of many converted

flats of its age. However, due to the presence of only radiant electric fires throughout

the flat and the louvred windows throughout the back addition, the likelihood of the

dwelling becoming unhealthily cold is significantly higher than for the average Pre-1920

dwelling.

Increasing the loft insulation to 250 mm, installing an efficient gas fired central heating

system and replacing the windows throughout with double glazed units would increase

the energy efficiency of the flat substantially and thereby reduce the likelihood of

excessive cold to better than average figures.

Although the risk of the dwelling falling to unhealthily cold temperatures and the

consequent risk of serious harm is higher than average, the spread of harms is not

increased in terms of its severity.
