Hi Lesley welcome to the community.
Have a look here at a few Firecrest photos where you will see the facial markings ww2.rspb.org.uk/.../196054.aspx
I'll find you some Goldcrest ones.

Here is Bob's photo of a pair of Goldcrests ww2.rspb.org.uk/.../1175259.aspx
Thanks Alan. - I'm now sure they are firecrest. They are the most gorgeous little creatures. They are very busy in the conifers -not sure if they are nesting? Been around for about 4 days - seem to be getting on well with my family of blue tits but the blackbirds is another story - seems to be lot of chasing by the blackbirds going one!
In reply to Lesley K:
One keeps flirting with his /her own reflection in the shed window! I'll try and get a photo.....
Good luck in getting a photo Lesley you might want to consider covering up the shed window, the bird is attacking its own reflection thinking it's a rival, they can hurt themselves.
Thanks for the tip Alan. I've just up a 'curtain' over the shed window. They are very speedy so yes I will need some luck to get a decent photo :)
