Your T2 (ICT) expires on 14 April and your last entry date into the UK will be on the 8th or 9th of April. This is within the period of your visa's validity.
If my UK visa ends on 14th April and I return from the Netherlands on 8 or 9th April will I be barred from entering the UK?
No. There is no reason (based on what you have written) for them to refuse entry.
An entry clearance ends on midnight of its expiry date. For you it means midnight on 14 April. As long as you are out of the UK by then, no problem. Note that your cooling-off period simultaneously begins at midnight on 14 April.
The reason I want to return to UK is that my return travel from UK to India will be arranged by my employer.
If the subject comes up, you can explain that to the IO. There is nothing particularly unusual about enjoying some free time near the expiry of a T2. The expiry on a T2 (ICT) is usually set at two weeks after the assignment finishes for reasons like that.
If you are travelling on an Indian passport, you will need a Schengen short-stay to enter the Netherlands.
