Before laying the laminate or wooden flooring ensure that your under floor is in good condition and is as flat and bounce-free as possible. Uneven areas should try to be repaired. The flatter the surface the better the wooden flooring will look.Ideally you will want the new wooden flooring to run length-ways along your room as this looks better than width-ways, however if your existing floorboards also run length-ways it is a bad idea to fit them directly together as this can lead to joint separation and unevenness. If this is the case then fit plywood over the entire floor surface so that you have a flat surface to then work on.
Once your existing floor is ready, lay an insulating membrane across the entire flooring area. This keeps heat in the room and dampens noise when the wooden flooring is walked upon and is highly recommended. Once this has been laid you are ready to lay your new wooden flooring panels. The easiest way is to work from farthest wall from the door inwards as this is the most seen part of the room. If possible remove skirting boards and door architraves so that you can work from the wall. If this isn't possible then beading can be fixed to these areas afterwards to give a tidy finish.
When laying the flooring panels always stagger joints by using random length flooring pieces as this will add to the strength of the flooring and the aesthetics. Ensure that all pieces are firmly locked together before re-applying skirting and architraves or adding beading. Flooring can contract and retract based on the heat of the room and moisture levels so do not fix skirting or beading to the floor. Fix skirting to the wall and fix beading to the skirting.
