You could try farms where they rent out unit space, these work out far cheaper, i missed out out on a good one £300 per month 1500sq feet. Some are offered inclusive, water, electric & rates etc. Just visit some near, you,ll be able tell them theres loads of small units around outside.
Mine is 750 sq feet at £3600 per annum which is a good price here, all in its approx. £100 per week. These are newish starter units with car park spaces & in there own estate.
The council ones are good if you have one near to you, there have short trerm agreements.
Stables is another, i used to rent space of one near me.
Also sublet, this is what i did befoe this one, & its usually cheaper.
Hope this helps.
To give you an idea of size, mine is full, but, we fit:
2 x vans
3500 litre storage tank & ro
A kitchen sink, washer & tumbler
carpet cleaners & vacuums, pressure washer
All chemicals for windows & other jobs
lockers
storage shelves & work bench
office & toilet
