dont know if im at right place here,

Yes

but here goes.just built a greenhouse 8x6ft,
ive tried all over the net for advice on heating,lighting etc.
can anyone help or tell me best place to find it.

How close is your greenhouse to an electricity supply?

Even if it's not close, and you don't want to risk mains there (for
whatever reason), you can run a low-voltage line down quite legally.
But, because losses are higher the lower the voltage, mains electricity
is better, as is, in the case of low voltage supply, heavy cable. (30
amp cooker cable isn't too heavy...)

Otherwise, it's perfectly legal to run a 'temporary' extension lead down
there.

If you want mains electricity in your greenhouse, the supply is now
goverened by the part (prat?) P regulations and can onlybe done
officially by a qualified electrician - ask in uk.d-i-y for ideas

If you want to heat the whole greenhouse, insulate it with bubble
plastic - but even then it will be very expensive.

No it won't. You can often get it free from white-goods suppliers.

Just cut clear polythene (from garden centre/seedsman 'cos it'll be
UV-stable) to size, spray with carpet adhesive, and stick bubblewrap on
patchwork-wise, then fix in place - you moght have to support it with
wooden slats/rails, as even the best tape will peel off with heat and
condensation.

If you only want to raise some seedlings in the spring, I have
successfully used a heated propagator. Build a tray 5 or 6 inches deep
and use this to make a heated bed using soil warming cable. Then mount
an aluminium cold frame on top (make the bed to fitthe cold frame) and
insulate the cold frame with bubble plastic. For the last 5 ears I have
had no problems raising seedlings using this system, starting in February

I made a large propagator by laying a waterproof tray over a
single-bed-sized electric blanket on a base of expanded polystyerine.
However, you must make sure such an arrangement is fed via one of those
leakage detector cutouts.
