- put aside money
Before starting try, really try, to have saved at least 1 months expenses - preferably 2 and ideally six. You won't get paid (as in a months salary in the bank) for a couple of months. companies have cycles for payments and if you are on the wrong end it can hurt
- know your tax liabilities
Sit down with your accountant and write a spreadsheet or a script that tells you exactly how much tax you owe to whom given say 10,000 of monthly income. Do not leave until this is done. Read this again. Trust me from bitter personal experience. Know your tax situation
- tax "dodges". You will be approached within days by someone hoping they can sell you on a scheme where you will pay 1% tax. Loans, off shore, forget all of them. Until you can afford your own tax lawyer, you pay what HMRC tells you.
Possibly the only "dodge" is if your spouse works for you and you split the shares of the company, each takin dividend payments - this way as a couple you have about 80k of income before a top rate tax is applied instead of just 40k if you are the only dividend reciever.
- good personal project management. No matter what half arsed system the client has you must always know what tickets you have, what the acceptance criteria are, and be able to report weekly to whomever. Even if you report to your Collegue or your own inbox the discipline is vital.
- have a "swapsies" partner. IR35 essentially says companies cannot exploit workers by calling them contractors. So there are several tests, the most convincing is substitutability - the idea if I am sick my company can send in another contractor just as good. Have a comtractor friend act as this person - it is a useful way to remember you are supposed to be a company not a person.
Shameless plug, but if you need to set up a substitution agreement with another company, i.e. a "swapsies" partner, checkout https://agree.digital. It's generally a good idea to have documentation in place you can use as proof if HMRC come knocking!
