Any ideas for work experience to get into vet school?

I’ve contacted over 15 practices and I need to do 70hours of clinical practice to get onto the course. Most won’t accept me because I’m not studying at university already and I would like to do it on a weekly basis so I don’t have to give up all school holidays of this year (I also have to do 70 non clinical). Anyone else struggle to find a placement and got any success stories (nearish to Derby, Nottingham or Leicester)?
TIA

Everywhere I contacted only offered a maximum of one week for work experience (if they did at all). As a result, I had to use all my annual leave from work to make it possible.
The only place where I gained regular, non-clinical animal handling experience was through weekly volunteering at a wildlife hospital.
Volunteering positions will require at least 6 months commitment (from what I have seen).
RSPCA offers volunteering on a weekly basis (you will need to sign up for job alerts, positions do become availiable but not often).
Zoos also offer volunteering, and they will always prefer someone who is either studying towards or aspiring to work with animals. I have met a few volunteers who were studying Animal Management Course when I did my work experience at a zoo.

Stables are always looking for volunteers to muck out, pick fields and clean tack so that should be relatively easy to find, especially if you only want to work on the weekends. But if you don’t actually go into the vet practice with a CV and get a face to face meeting, obtaining any clinical wex will be nearly impossible.
You say you don’t want to give up your holiday time, but have you thought of a working holiday. A fair few on the vet med thread over the years have gone to ARA on the Algarve. It’s an animal rescue centre developed by a British expat who provides housing to students and travellers in exchange for a few hours work with the dogs and cats that have been rescued.

Otherwise you could always try to find a lambing placement on the national sheep org website. Normally they will provide accommodation and quite often you don’t require prior experience

Do farm work if at all possible. Find a farm with a sizeable herd of dairy cows, ideally those who block calve (everything happens in one big lump so busy busy busy) or who calve all year round (steadier but always something somewhere ready to give birth)- this will give you big big big experience of large animal work at the sharp end. Lambing generally happens in the earlier part of the year with peak activity Feb-April depending on how the farm does it. Being able to say yes, I spent the Easter holiday looking after calves/lambs on my own is a big deal in interview and you'll be able to actually do stuff yourself rather than just shadow or do things under supervision constantly.
You will generally struggle to get hands on experience with any sizeable pig or poultry unit because of biosecurity concerns so don't be surprised if you find this inaccessible. It's quite niche/specialist also.
Farm work: with larger animals takes confidence just to be able to handle them appropriately and safely. Start learning this early and you will remove a big chunk of the large animal job as it will be less intimidating/daunting. Rest assured that even if you are a smaller/shorter person, female etc etc etc, you will be able to work competently because skill and technique is far more important than any amount of physical strength in the large animal world.
Also begin working on client-facing skills. What is your client's overall aim or expectation? Why do they keep animals this way? What motivates them? What animal welfare/health problems do they face and what do they do about it? Maybe you have no intention of ever working in large animal practice- that's AOK but this experience will spring-board you in interview. Smally practical experience is far harder to come by because it's so popular. Try to round-out your application and be as broad as possible. Apply to work in animal sanctuaries and shelters, zoos, farm parks, etc. The more exotic the better. Keep a detailed diary of every day and the requirements and needs of each species or any system you work in.
Anything you can list down as experience is very useful.
