Birmingham City Council Resident

Testimonial

“The recent refurbishment work has made a huge difference to our lives. My flat used to be freezing, and my electricity bills were up to £400 a month, but with the upgrade it’s now warm, cosy and quiet – and my bill is around £90. Inkerman House looks better than I ever imagined, and the work is truly appreciated for the positive impact it’s had on our family.”
