Assuming no cold feed for the dishwasher you will need to T off one from the cold supply first – i think most just need a cold feed these days.
Then line up the hot & cold to approximately where you need them for the sink. Worth planning this carefully to avoid tight turns / drilling around cabinets / under the basin etc.
Simplest is to then get some push-fit mixer tails if its a mixer tap, like these : http://www.wickes.co.uk/flexi-hose-pair-monobloc-mixer-spdfit/invt/227312/. Or a compression join equivalent. Just get the right size for your tap (important bit). Make sure tap is suitable for your water system (ie high / low pressure).
Like footflaps my preference would be to solder / compression join all the pipes in copper. I have always used gunk (jointing compound) rather than tape for the compression joints (ie on the ‘olives’) – never failed me yet. Just dont go too tight with compression joints at first, nip them up gradually if any sign of weeping water.
Then get a all-in-one waste kit (see pic above) and run the dishwasher outlet to the small Tee on the waste trap.
Again +1 for Wickes / or even Homebase have some good guides on their website / in-store.
Put kettle on. Enjoy with biscuits.
