They look OK, still a little spindly. Give them as much light as you can-- full sun once they are hardened off to it. The next time you repot them, really bury them deep, all the way up to the first true leaves. If they are staying in pots, then eventually they will need to be in pots at least the size of 5 gallon buckets.
Have you told us where you are? Much of the US, it is either time to start bringing them out to harden off (I'm bringing mine out for the first time today) or will be soon.

I'm in Yorkshire in England. It's not the hottest place on earth but there has been plenty of sun recently and my house has long windows that stretch across 2 floors so light has not been a problem.
I think I underestimated just how tall they were when buying new pots. How long before it is safe to transfer them again?

If you are willing to re-do them, you can do it right now. I readjust the height of some of my seedlings just so they can stay under the lights by dumping them out (carefully support the solid around the seedling), loosening to remove soil mix at bottom and generally flattening the foot mass, the carefully lowering them to the bottom of the pot/container.

Ah. I was puzzled that the link and info I posted wasn't here. It was in reply to another thread:
Subject: Seedlings too tall and leggy plant a week early in garden?
Subject: Seedlings too tall and leggy plant a week early in garden?
Hmm... Noticing advice above was for bigger plants, so 16 oz - 1 L/1qt - 24 oz containers should work for seedlings your size.applestar wrote:Are you supporting them at all?
Use thin bamboo canes, bamboo skewers, straight shrub and tree trimmings (upside sown if fresh cut to prevent rooting). They will need the support when they go outside to harden or a little breeze will knock them over.
If in doubt, you can also deep uppot to Large and Double-gulp cups, cut off 1/2 gal milk, etc. beverage cartons, 2L and 3L soda bottles, etc. -- WITH DRAINAGE HOLES OF COURSE. Drop them in the bottom and fill with fresh potting mix to the top, burying the stem.
You can also make DRAINAGE SLITS with utility knife/box cutter as described here:

Watering is always best done from below. Tomato plants don't like to be overwatered, so it is usually a good idea to water when the top of the soil looks dry and a lighter in color, or just feel them. If it feels dry when your finger is inserted to past the fingernail, it's time to water, but not before! Tomato plants don't do too well with wet leaves, they can get fungus, so be sure to water so that the leaves stay dry.

Hello again. Ok, my plants seem to be making really good progress. They have grown to be about 20-25cm. Should I begin to harden them off a bit ready for the great outdoors?
I don't have much of a garden so I think I am going to have to plant them in large pots. Has anyone done this before in here?
As always any advice is appreciated.
Thanks

Yes. They are looking good and plenty ready to start hardening off.
Lots of people grow tomatoes in containers. What you need is LARGE containers (at least the size of a 5 gallon/ 20 litre bucket for ONE plant) and plenty of sun. And then they will need considerably more care and attention than if they were in the ground. You will have to fertilize some and you will have to monitor their water needs carefully. I tried doing this one year and never got it to produce much, because it kept drying out. But it was a very hot, dry summer, more than I think you usually have. But if you are having hot dry weather, then you would probably need to water it every day, possibly twice a day if it is really bad. Or set up some kind of irrigation or self-watering system.
But if you are prepared to give this level of care, then sure tomatoes can do fine in containers.

I don't think you ever said what variety tomatoes these are.
Some varieties have significantly different growing habits. In UK and Europe, the usual practice is to prune them to a single stem, so I'm kind of leaning towards guessing that they are an indeterminate variety that grows no more than 6 foot or so and you'll top them anyhow, but tell us what you are growing in case you have determinate varieties that tend to be shorter and shouldn't be pruned or patio type short/sprawling varieties that are meant to be grown in containers.
That will determine the best size.

I haven't container grown tomatoes very much, but I want to say ideally at least 10-15 gallons or 40-60 liters -- 15"x15"x15" box -- for each medium sized plant if you want good production and full size for the variety fruits.
I have grown medium sized varieties -- 4-6 ft -- in my 14"x14"x14" patio boxes. They tended to get stressed but did OK.
I believe it can be managed with 5-7 gallons if you do single stem pruning and rig self-watering or automated watering. Have you seen the rain gutter self watering design for 5 gallon bucket garden? If I had a level surface to set these up on, I might try this with the floating switch valve automatic waterhose intake.
Earthbox type commercial or DIY container is another option. I have heard that you can actually plant two tomato plants per genuine Earthbox.
