If you use someone who is not directly employed by you, then they will need to have all the relevant insurances otherwise you will end up liable for any damage etc.
Also, they will be responsible for their training, tax national insurance etc and so will have to find this out of the money you pay them.
It is far cheaper to take someone one on PAYE, especially if they are only part time.
The drawbacks are that you have to pay them sick pay, holiday pay, public holidays, regardless of the weather etc. You also have to pay the extra insurances, training, H&S etc. You will also need to monitor their quality of work as it will never be of the same standard as you would do it.
My advice;
- don't let the above put you off, but just make sure you are ready for the extra paperwork.
- don't try to do it 'on the sly' as if you get caught the consequences can be severe
- make sure you can afford to pay them week in week out as YOU get paid second once you take on an employee
- talk to your accountant and make sure that they are confident you can afford it as they will be the ones who have to help you pick up the pieces if it all goes pear shaped
- I am talking from bitter experience so this is not fanciful guesswork or supposition
- if it doesn't work out first time, don't let it stop you trying again.
Good luck, done right this will make you a lot of money I hope.
Kind regards
