When flying in the UK you need to keep your aircraft within 500m horizontally of yourself, below 400ft above ground level and within visual line of sight. If you are able to satisfy these conditions, then you should be able to safely fly the aircraft from your home to the location, take the pictures, and return home.
If, however, you cannot meet these criteria then unfortunately you are unable to complete this flight safely during the lockdown.
Information on UK flying regulations, including distance rules, are available from the Drone Safe website - this is well worth a read, especially the "Drone code" page, and knowing this information will help when/if registering as a drone user.
You should also give thought to what you would do if you had an in-flight emergency - if your drone crashes or you have to land away from home, will you be able to recover it?
