Not quite sure which course you meant by "forensic investigation", a quick search led me to Canterbury Christ Church University
https://www.canterbury.ac.uk/study-here/courses/undergraduate/forensic-investigation-19-20.aspxthere are other universities offering similar courses, however this course has interesting facilities
The forensic facilities include a range of crime scenes, including cars, crime scene rooms, fire scenes and outside scenes and a forensic workshop and range of science laboratories. A wide range of forensic equipment is housed within these areas and the facilities and equipment used depends on whether you study Forensic Investigation as a single or combined honours degree.lets have a bit of a look in more detail (from the link above)
it covers
A) police investigation
B) cybercrime
C) forensic intelligence and research
D) the criminal justice system.
translating that to traditional degrees, you'll see why soon
A) is basically sociology/criminology
B) is basically applied computer science
C) is a bit undefined in my opinion, probably mostly chemistry
d) is again sociology/criminology
from my point of view in a research environment, this course would certainly be very interesting, but is
unlikely to give much future employment directly in forensic research...this is because most post degree candidates for Forensic Science would have studied a more original, in depth,
traditional course, such as BSc chemistry, this is where forensic recruitment will look first, ideally also with criminology and other specific knowledge
It is similar to how recruitment to , say , a BBC Radio Station tends not to be from Media Studies students, but BA English students.
Due to the "hit TV show" CSI/Las Vegas/Miami/New York and the UK's Silent Witness, Forensic Science has
never had a higher profile, whilst sadly
not actually existing in England & Wales due to the abolition of the Forensic Science Service in 2012quoting headlines from very recent news articles,
Financial Times 30 April 2019 - The forensic science system in England and Wales is in a crisis ... Funding cuts including the abolition of the government's Forensic Science Service... forensic work ... suffering as a result of austerity-related spending cuts
Police forensic science at 'breaking point', warn peers...UK
was once a world leader in forensic science...
ITV news website 1st May 2019 Forensic science 'inadequate' in England and Wales as House of Lords report warns it has reached breaking point
Services that are pivotal to the criminal justice system are “in trouble”, according to the House of Lords Science and Technology Committee.Peers suggested a number of factors had contributed to the problems, including an absence of high-level leadership and a lack of funding.The “quality and delivery” of forensic science in England and Wales is “inadequate”, the report said.It argued that unless failings are recognised and changes made, public trust will continue to be lost, adding: “Crimes may go unsolved and the number of miscarriages of justice may increase.“Forensic science in England and Wales is in trouble. "To ensure the delivery of justice, the time for action is now.”The [House of Lords] committee’s chairman, Lord Patel, warned that the current situation “cannot continue”.He said: “Our forensic science provision has now reached breaking point and a complete overhaul is needed.That's just background, it is currently messy, and there IS a need for trained Forensic experts, but the best route would be, in my opinion, take a classic degree in Chemistry (if you like science) , or take a degree in Computer Cybersecurity (if you like computers) or take a degree in Sociology/Criminology if you'd like to eventually be the BOSS of whatever future Forensic Science Service the UK finally adopts. In any of these degrees there will be specific "forensic" = "analytical" modules that you can take, to push your degree course in the direction that you yourself prefer.
Sorry for such a long answer, but you asked a great question - it IS possible, but there might be different ways to do it better than a "Forensic" degree,
such as these Criminology or Chemistry with Forensic courses
Durham Criminology BALiverpool Criminology BADundee Forensic Anthropology BScHull Chemistry & Forensic BSc (Hull also do Criminology & Forensic BA)
check-out also UCLAN, Keele, Surrey, Lincoln, Strathclyde, not forgetting Oxford & Cambridge
(Oh, and in Scotland, they thankfully still have their SPA
