I am sorry. I just noted that you said "import from amazon.co.uk". Amazon, UK will not ship electronic items directly to India. You will have to use Aramex Shop & Ship or Borderlinx. Amazon.com (USA) will ship to India. Amazon, UK price will be much higher.
You can also visit "Projector Central" or "Projector People" for deals.
Most projectors have universal voltage (110~240V, 50/60Hz). But check and confirm the specs.
