Are these Ash trees?

I have two trees growing closely together on my front drive. They are self seeded. They look like Ash to me but I not an expert. They are about the height of the house and have not stopped growing yet! I am a little concerned, as they are close to the house. I was hoping they might be some sort of ornamental or dwarf variety (there are others similar on the street which are smaller). But this one is getting bigger each year. Can anyone identify them? Leaves are on the two trees are similar to each other but one has brown fuzz on it rather than seeds.

 

It does look like Ash.
Probably best got rid of, most self seeded trees are usually problematic after a few years.

 

Yes get rid of them, they will become huge and cause problems for your house.

 

i dont think your trees are Ash (Fraxinus Excelsior)
See :
Ash (Fraxinus excelsior) - British Trees - Woodland Trust

Don't think it's our native ash, leaves are wrong. Could be Fraxinus ornus the manna ash
Would still get rid.

 

I did think that the leaves of them was not quite right but the seeds tend to suggest an Ash of some kind.

 

Leaves seem to differ photo 3-4, Op says there are two trees. Agree that one seems likely to be Fraxinus ornus, it would be interesting to see photos of the bark of each, as this may assist. My other thought was Acer negundo ?

The seeds appear to only have one wing to me.
There does seem to be variation between foliage but they are both very similar.
Being self sown I'd be inclined to guess both seeds came from the same tree.

 

Fraxinus ornus is extremely rare in UK...very easy to id from the buds.
3 and 4....Pics below ..shows a single leaf with leaflets.

 

See also above.
Pics below are Fraxinus excelsior.
Easy in winter by the buds.
