Do trailers only used for storage need to be on O Licence?

Hi all,

I have been advised by DVSA to send an email to notifications@vehicle-operator-licensing.service.gov.uk,
they could not give me an answer and I believe the guy on the phone was worried about making a decision…

Any thoughts? Email as follows:

Dear Sir / Madam,

I have been given this email address by one of your colleagues over the phone (DVSA helpline)
as I have a query relating to a potential O Licence change that we may or may not need to make.

I work for a national company and operate a fleet of 7.5T and 17T vehicles from an O Licence site in Southampton,
all of which are registered on our O Licence, along with a single trailer which is permanently attached
to one of our loading docks and used for additional warehouse storage only. We do not have any
motive units and this trailer was dropped by one of our other O Licence sites which operates these larger vehicles,
based in Bournemouth, 1 year ago.

My first question is, does this trailer need to be on our Southampton O Licence?
It is registered currently, as we could not find a straight-forward answer to the question and
it was added to be on the safe side. This trailer is not operational (VOR’d) and would need to be
recovered / disposed of, should we stop using it for storage purposes. Also, are there any rules which state
that this cannot be permanently ‘parked’ on a loading dock for storage-only purposes?

My second question relates to us adding additional ‘operational’ trailers for further storage.
Our O Licence site based in Bournemouth have offered us 2x additional trailers which would be used
for the same purposes as above, for a period of 3-4 months, at our Southampton site.
Our Southampton site cannot ‘operate’ these as we do not have any motive units.
These trailers are registered on the Bournemouth site O Licence and would be dropped by their motive units at our
Southampton O Licence site. These would be subsequently attached to 2x of our loading docks and left there.
As these trailers are on the Bournemouth O Licence and are operated and maintained by them,
do we need to move them to our Southampton O Licence for the time they are here,
considering they will not be operated by us and just used for storage only? Would the 28-day rule
apply here for trailers and would they need to be moved / swapped after this period?

Hopefully you can help as I have not been able to find an answer to this question,
The helpline are hesitant to provide an answer in case I have explained the situation inaccurately.
Please let me know if you require any further information.

Regards,
