Self-employed, claiming travel expenses at 45p per mile

I am a self-employed sole trader and offer different services to different clients. I travel to one client’s house approximately2- 3 times a week for most of the year, can I claim travel expenses (tax relief) for this? I have a freelance contract doing a different type of work with a charity and spend approximately 15 times a year travelling to their site, can I claim travel expenses for this job? I have another self-employed freelance contract offer a different type of work and work on the clients site once a week, can I claim travel expenses for this job? My main base is working from home. For all my different types of work I am required to travel to different shops to purchase consumables, and find resources from different locations, Can I claim travel expenses for this ?  I have attended the HMRC Webinar on claiming expenses but was unable to find the answer for my particular circumstance.
