If you work through an agency at the same client and location all the time then this does rule out tax relief on travel expenses as it is a normal place of work.However, no matter if through an intermediary or not, there is still the concept of a temporary workplace. It is a fairly complex area, but if you are not working continuously at a client then it can be argued that each place you go to is a temporary workplace.
An example might be an agency driver that works fairly ad-hoc and goes to many different clients, maybe for a week here and there and shifts are to a large extent confirmed the day before.
If shifts are confirmed the day before with absolutely no guarantee of any hours, then it can also be argued that you are not in continuous employment, because the agency could decide not to call you at any time. If you were to be put on a rota where you had an expectation of staying on for a period of time, this would effectively mean that you have a normal place of work and no tax relief would be possible on travel.
This is my take on it anyway. I have claimed tax back on travel for a few years. I have had the spreadsheets ready to submit to HMRC, but they have never requested them.
HMRC state that if you work in a defined geographical area, any travel from home to the edge of that area, and back again, is ordinary commuting and you cannot claim the costs of that part of your journeys.
Also;

Where a worker provides his or her services through an agency and the agency legislation in Section 44 ITEPA 2003 applies, each agency contract is treated as a separate employment, see ESM2000 onwards. Therefore, where there is only one workplace for an agency contract that workplace will be a permanent workplace for that employment.
The example that HMRC supply, might look familiar to how you work on agency…
Travel expenses: travel for necessary attendance: fixed term appointments and agency workers: agency workers: example
gov.uk/hmrc-internal-manual … l/eim32131
An employee is an accounts clerk who gets all her work through an employment agency. She rarely takes a job that lasts more than 2 weeks. She travels from home direct to the premises of the employment agency’s client. No deduction is due for her travel expenses between home and client’s premises.
Each job is a separate contract of employment, see EIM32130. Each of the client’s premises is a permanent workplace because her attendance at those premises will be for all of the period for which she will hold that employment, see EIM32125.
And for the OP this is why the mileage claims are illegal from the same link above.
From 6 April 2016, new tax provisions for the treatment of travel and subsistence expenses for workers who personally provide services through ‘employment intermediaries’ apply. The employment intermediaries travel expense provisions mean that each engagement undertaken by a worker who personally provides their services through an employment intermediary will be considered a separate employment for the purposes of travel and subsistence. This will mean that generally no relief will be given for home-to-work travel costs and associated subsistence.
So pretty much everyone who has been claiming travel expenses from home to work either as a self employed driver or an agency driver has been claiming them against HMRCs rules. And just because they’ve not said anything doesn’t mean you haven’t.
