Shopkeepers on Housing Society properties may apply for rent reassessment from today. A spokesman for the society said all 370 of its commercial tenancies would be eligible for the review, prompted by the recent downturn. The move follows a rent review offered by the Housing Authority to 9,400 shops operating on its housing estates in June. Some of those shops had rents cut by up to 60 per cent after the assessment. Applications will be considered on an individual basis taking into account a shop's trade, location, size and surroundings. The review is expected to take three weeks after applications are received, and unlike the Housing Authority's review, this re-assessment will be free. The spokesman did not want to estimate the cost of the review but said it would not be much. 'Sixty per cent of the shops have been re-assessed in the past 18 months and still maintain rent levels of 1995 to 1996,' he said.
