Up until now I have been planning on claiming I have worked in NOC code 2147 'Computer engineers (except software engineers and designers)'. However I looked a bit closer today and it says that a BSc is an 'Employment Requirement', and I do not have a degree.

I do have a 1 year post-graduate diploma from OU that I got purely for immigration reasons in computing/IT.

My job timeline is as follows:

05/2013 - 11/2015 Technical Advisor (Tech support for computer hardware)
11/2015 - 02/2016 Technical Engineer (Tech support for managed email/SaaS provider)*
02/2016 - 05/2017 NOC Engineer (Network support/troubleshooting for an ISP)
05/2017 - 02/2018 Managed Service Engineer - Networking (Network support/design for a managed service provider)
02/2018 - 09/2018 Network Consultant (Promotion at the same company from above, basically moved purely into a network design job)
09/2018 - Current Network Solution Engineer (Purely design and network delivery, I intend to work here up until the day I immigrate).

*This was only a 3 month contract and am considering not declaring this at all, as getting proof of employment may be difficult

My previous understanding was that I was in a 2282 (User support technician) role up until 2016 when I started as a NOC engineer, then moved more into 2147 role... but am feeling a bit lost and discouraged after reading that degree requirement.

You select the NOC based mainly on the duties so if you are doing mostly the duties described you can use that NOC. However, without the usual education requirements you will likely need to spend a little more effort to clearly show you are completing those duties. If you have other training these may also help.
