Paint for walls. Ceilings and wood (Wolverhampton WV1)

Just moved (see other posts) and money is a real issue. Ceilings and walls currently bare but they are smooth so we wish to.paint them.
Does anyone have any decent amount of emulsion for walls, white emulsion for ceilings, undercoat/ primer for woodwork (skirting and doors).
We are not precious, happy with previously opened tins. Any brushes or rollers also would be very gratefully received.
Can you help with this request?
