We're buying a new fridge/freezer, and found one we like in Currys, so we ordered it online. A week later, delivery was due (yesterday). I received a 'courtesy call' on Saturday to confirm it all, and all seemed well.
Firstly, the delivery was late - maybe 30-45 minutes later than the end of the 4 hour delivery slot. About 20 minutes before arriving, the driver called to say he was on his way (nice!), but then said "oh, er, top flat?" and proceeded to explain that the fridge we had selected was classed as an "American style fridge/freezer", and so they wouldn't be able to take it upstairs. On arrival, they took one look at the stairs and flat-out refused to do anything more - not even to try, so we refused delivery and sent the goods back.
Naturally, I called Currys and got passed to a couple of people, both were generally unhelpful and unsympathetic. They ended up re-iterating the same line, that they wouldn't deliver American fridges up more than four steps. At no time during the buying process did anyone at Currys ever describe this fridge as "American style", much less that there may be any difficulty delivering it.
In short, Currys Home Delivery appears to be "only if it's easy". If basically, they can drag your items along on a trolley to their final resting place in your house, you may be okay. If there are awkward corners, steps or other obstacles, they won't bother. Oh, and don't expect any sort of help if it's getting close to the end of the shift either.
Of course, now we've found this out, we can find any number of sites on the Internet confirming how rubbish Currys are at delivery. Here a couple:

Although a quick web search fill find lots more!
Update: We tried M&S Appliances. They're basically the same people (DRL), but offer a completely different experience. For these guys, nothing was too much hassle, the delivery done swiftly, tidily, and problem-free. It turns out they're about the same price as Currys too (especially if you include delivery, recycling, etc), so clearly a far preferable option.
