Should tenants receive compensation for delayed hot water repair?

Hi, I have two tenants in an all-electric property, and both elements in the hot tank failed. The thermal reset worked for a while, and I tried changing the thermostats, but neither solved the problem.

The repair took about six weeks in total to complete. Contributory factors were the contractor not being available and the tenant not willing for me to accompany a contractor.

I lent the tenants an urn so they could at least do the washing up. They have an electric shower, and the property has heating.

The two tenants are a gentleman who has some autistic issues and a lady who has various health issues. He has just moaned a bit in WhatsApp messages, with no formal complaint.

I don’t know whether they have any recourse under the tenancy agreement or the new Renters’ Rights Act. Any payment would be a goodwill one.

What do you think I should offer the tenants in compensation, if anything?

Thanks,

Mike
