(HMRC) Is it required to register at customs in the UK?

Yes. HMRC means “Her Majesty’s Revenue and Customs”. This government company realizes taxes income for the United Kingdom. At the beginning of 2019, the United Kingdom has a VAT legislation (VAT notice 1003) in place which makes it compulsory for the sender to always pay the VAT for parcels ≤ £135. In other words, do you ship products with a value of less than 135 pounds? Please register via the website of the HMRC in the United Kingdom.
