I was under the impression that Virgin HEMS do not own GEHMS and that they lease it from some finance related company. I believe that PAS/MAS do not own the airframe either and only have a contract to service it.
It would seem logical and cost effective for Virgin HEMS to apply for an extension to the lease and continue using GEHMS. Last time I saw it, it looked to be in an extremely good condition and I doubt whether it has many hours on it compared to other 902s of the same age.
Without wishing to get into the 'hamster wheel' argument, the small profile, lack of tail rotor, low noise and large cabin make the 902 ideal for city HEMS work.
