If you need to work from home on a regular basis, either for all or part of the week, you may be able to claim tax relief for additional household costs, including:
Your gas and electricity
Metered water
Phone calls and internet access.
You won’t be able to claim for the whole bill, just for what you use when you’re working from home, and you won’t be eligible if you chose to work from home. Find out if you’re eligible to claim for tax relief.
