I would recommend you have a word with your company boss. Maybe, they will increase your house allowance.

You could also give them an ultimatum.

My personal experience, when my house rent was increased, I informed the company and they increased my allowance. Now, after one year the landlord wants to increase the rent again. God help us. The company is willing to increase my allowances but not my salary. Increase in allowance is better than nothing.

All the best Sujeshjs
