Money ejected early from 1 year product - will I get bonus?

Just to clarify: as long as you leave it on loan in one of the three markets. Having it in your holding account isn't enough.

In my experience, the £100 is paid around 30 days after the 1 year period is up. I entered RS in June 2018, and received my bonus a few weeks ago.

I think that should be ok, but you could email RS before removing the last £1,000 from Everyday.  T&Cs were as follows in November:

£100 for £1,000 Promotional Terms and Conditions
1.You’re eligible for the bonus if you:
a) Have not previously invested with RateSetter.
b) Register by clicking on the promotional link and open a RateSetter account.
c) Invest through the RateSetter ISA or Everyday Account within 8 weeks of registration (by putting your money on loan in any of our markets or combination of our markets).
d) Register on or after the 4th April 2018.
2. You will qualify for a £100 bonus if you invest and put on loan a minimum of £1,000 within 8 weeks post registration and keep this invested for 365 days.
3. Your minimum £1,000 investment can be made up of new subscriptions and/or transfers from other ISA providers. It should take no longer than 15 working days for a Cash ISA transfer, and 30 working days for a Stocks & Shares ISA or an Innovative Finance ISA transfer. Please note the time it takes for your ISA to be transferred to RateSetter is dependent on your current ISA provider and may take longer than 30 working days.
4. The maximum bonus per customer under this promotion is £100.
5. Earned bonuses will be credited to your Everyday Account and invested in the Rolling Market at market rate within 30 working days of qualifying. The Rolling Market will reinvest the bonus each month automatically. You can change your investment settings and request to withdraw your money at any time (subject to the Investor Terms (/investor-terms/)).
6. This bonus is not available in conjunction with any other offer – but you can still refer friends to RateSetter and earn ‘referrer’ bonuses.
7. The promoter of this offer is RateSetter (a trading name of Retail Money Market Ltd), 6th Floor, 55 Bishopsgate, London, EC2N 3AS and we reserve the right to amend or withdraw the offer at any time.

I think they said once before its ok to be in holding, or even on the market and not lent as long as your clearly not gaming the system.

I suspect the bonus is manually applied and hence someone checks the position of the account.
If the/any loans repay early then thats not your fault, if you were to however put the reinvenstment at say 10% then they may well likely not payout since you would be clearly trying not to relend the money

According to @inv11 's post above
So I guess you need to wait up to 6 weeks before it will arrive in Rolling. After that if it's still not arrived then I'd be on RS's case.

Edit: Not sure but to qualify perhaps the starting point is when it is fully invested to a product so it could be later than you might think. I could be wrong on that one though yet...
My highlighting on that one.

Neither of my parents received their £100 bonus. Miraculously their 12 month investments re-paid early and were briefly held in their holding accounts. After 3 months of chasing RS to find out why their bonuses hadn’t been paid – RS finally trumped up with this excuse. Leaves a very bad taste – both have now withdrawn from RS as a consequence.
