Tickmill broker is a group that has several companies under it, namely:
Tickmill UK Ltd - regulated by the UK Financial Conduct Authority (License Number: 717270 and Registered Office: Floors 3, 27 - 32 Old Jewry, London EC2R 8DQ, UK)

Tickmill Europe Ltd - regulated by the Cyprus Securities and Exchange Commission (License Number: 278/15 and Registered Office: Kedron 9, Mesa Geitonia, 4004 Limassol, Cyprus)

Tickmill Ltd - regulated by the Financial Services Authority of Seychelles (License Number: SD008 and Registered Office: 3, F28- F29 Eden Plaza, Eden Island, Mahe, Seychelles) and its 100% owned subsidiaries

Procard Global Ltd (Registration Number: 09592225 and Registered Office: Floors 3, 27 - 32 Old Jewry, London EC2R 8DQ, UK)

Tickmill Asia Ltd - regulated by Financial Services Authority of Labuan Malaysia (License Number: MB/18/0028 and Registered Office: Unit B, Lot 49, Floor 1, Block F, Lazenda Warehouse 3, Jalan Ranca-Ranca, 87000 FT Labuan, Malaysia).

Of the five Tickmill-owned companies above, the safest subsidiary is Tickmill UK Ltd which is regulated by FCA UK because FCA UK is a credible regulator. However, Tickmill UK does not accept clients from countries other than the UK.

I personally traded for 6 months at Tickmill SC with a small capital of under $1,000 and the service was satisfactory: small spreads, never requotes, fast deposits and withdrawals (I use Fasapay). However, I don't recommend trading there using large funds (>$5,000) because regulation is less secure.
