HK Resident/UK National- Where should I save my money?

[JoJOh]

Looking for some advice on savings & investments.

I currently live in Hong Kong SAR having been working here for 1.5 years.
As I currently have money in both U.K and HK Bank Accounts, I wanted some advice on how to streamline my finances to make sure I'm getting the best value.
Please see a summary below.
Any help would be greatly appreciated.

I intend to save approx $6500 HKD (£641) per month going forward to contribute to savings.

Hong Kong Finances
HKD $55706 (£5496) Savings Account
HKD $113794 (£11228) MPF (The Mandatory Provident Fund, often abbreviated as MPF, is a compulsory saving scheme for the retirement of residents in Hong Kong. I'm unable to withdraw from this unless I officially leave Hong Kong)
HKD $31000 (£3058) Invested in a house deposit (Hopefully will get this all back upon leaving the tenancy)

U.K Finances
£1063 Current
£5793 Savings
£1580 Help To Buy I.S.A

Thanks
