I have had problems with this in the past. I went to Allied Carpets and chose the carpet, had them out to measure, went back to the shop to order when I received the estimate and just happened to mention the problem with the furniture and the guy told me they didn't lift furniture the room had to be cleared. When I reminded him I was spending approx �1,000 and I would pay extra he was most un-cooperative so I told him to stick his carpet and walked out. I finally bought from a small local business and I was quite taken aback at the estimate as it was �150 cheaper. I would mention your problem when ordering. The carpet fitters I had said they came across this all the time and it wasn't a problem. So it really depends on the shop you buy from.
