Income from property and standard personal allowance

I live in UK for two years and my income composes of pension from the Government of Hong Kong and a rental income from a UK property.
As far as I know, the pension from Hong Kong Government does not need to be included in the UK tax return.
My annual UK property income is below the Standard Personal Allowance. Do I still need to do a tax return?

Hi Tabby
You must report your income from property in a Self Assessment return if it exceeds £2,500 per year after allowable expenses, or it exceeds £10,000 per year before allowable expenses. 
The application of the tax-free personal allowance may mean that no tax is charged on the property income, but the property income still needs to be reported in a Self Assessment return if the £2,500 / £10,000 limits are exceeded. 
We provide a tool that customers can use to check if they meet the Self Assessment criteria, which is available at Check if you need to send a Self Assessment tax return.
Thank you.
