London hiu maintenance

After spending over £1200 in the last six month trying to fix my hot water by other contractors I thought I will give this company a chance. They used some equipement and confirmed the issue is not in my HIU but the neighbour valve is open which is affecting my hot water. They fixed the valve for my neighbour and since then my hot water have been working. I must tell, they really know what they are doing.
