MAJOR conferences have been providing a significant boost to hotels in Glasgow and Edinburgh.

However, the hotel sector in Aberdeen has seen a year-on-year decline in revenue, according to accountancy firm BDO's latest monthly survey of three and four-star properties, with weaker oil prices cited as a possible reason.

The BDO survey shows a strong year-on-year rise in revenue for the hotel sector in Scotland as a whole.

Glasgow hotels' revenue per available room, calculated by multiplying occupancy by average room rate achieved, came in at £73.19 in September, up by 35.1 per cent on the same month of last year.

BDO cited the beneficial impact on hotel bookings in the city from conferences staged by the European Consortium for Political Research and the Cardiovascular and Interventional Radiological Society of Europe.

Alastair Rae, a partner of BDO, said: "Glasgow continued its strong summer after the Commonwealth Games, with more than 8,000 delegates attracted to the ECPR 2014 Conference and the CIRSE congress."

Edinburgh hotels achieved a 27.2 per cent year-on-year rise in revenue per available room, also known as rooms yield, to £98.47 in September.

BDO said this had been driven by visitors who were in the Scottish capital for the end of the festivals and by medical and scientific conferences.

Scottish hotels achieved rooms yield of £81.49 in September, up by 21.4 per cent on the same month of last year.

Hotels in Inverness recorded rooms yield of £56.91 in September, up by 11.2 per cent on the same month of 2013.

However, Aberdeen hotels saw a 5.9 per cent year-on-year fall in revenue per available room to £80.95 in September.
