Hi Lucy, and welcome to the HUBB!
Check out this link
for a shipment from Delhi to Boston from the Shipments by Travellers page (see Menu to your left for more information from the rest of the site).
Cat Syrbe shipped an Enfield from Delhi to Boston in 2001, and was satisfied with the shipper. Price for air shipment was US$350 including crating. Contact details are at the link above.
UK port charges can be quite high, so if you're deciding between air and sea, make sure you get all the costs. See this link
for Richard Vir's experience of a sea shipment into the UK from Malaysia. 75% of his costs were for port charges!
As for importing and registering the bike in the UK, assuming it is an Indian registered bike, there are Customs issues and licensing / registration issues you will need to research.
Here's some links to HUBB posts to get started:

Carnet for Indian-bought bike
For DVLA registration, try these links:
DVLA - How do I import my vehicle into Great Britain?
DVLA - Vehicles - Import and Export
I would suggest you do your research on the customs and licensing issues before arranging the shipping, as you might find it is a lot of hassle.
Good luck and please let us know how you make out by filling in the Shipping Form for the benefit of future travellers.
