Transatlantic air fares can be cheap, but Derby is still quite a long way from London Heathrow. If you take the Heathrow Express from Heathrow to Paddington (and plan on returning the same way; i.e., a return [roundtrip] ticket), it will set you back £27 (about $47). A ride on the London Underground from Paddington to St. Pancras will cost you £2 (about $3.50). You can then buy a return [roundtrip] train ticket from St. Pancras to Derby, which can cost you up to £98 (about $170). Luckily, Alvaston is within walking distance from the Derby railway station.
Depending on your flight schedules, you may also need lodging and food. Be prepared to pay at least £70 (about $120) for a night in a semi-decent London hotel room. And, as Lolly Pop already pointed out, Big Macs are £2.99 (about $5.20) apiece in the UK.
