13 year tenants responsible for professional carpet cleaning?

Hi all, I was hoping someone could weigh in on this, as we’re having a bit of a debate.

My friend has been living in her flat for 13 years since she was a child. Four years ago, her parents moved out and her name went on the lease. Two years ago, I moved in and joined her on the lease.

We are now moving out at the end of this month. The landlord came by to take a look at the place a few days ago. Honestly, everything is in really good condition not just for a 13 year tenancy, but in general.

However, he kept commenting on the carpet and how dirty it was. For the record, this is cream coloured carpet that has been in constant use for 13 years. He’s insisting we get professional carpet cleaners to come by.

I fought back and said that I thought a standard, thorough end of tenancy clean that included hoovering would be sufficient, which he did not like.

I believe that after 13 years of use, the general wear and tear of the carpet that makes it look dirty cannot possibly be our responsibility.

We are just starting out in our careers and have very little money so the £280 for the end of tenancy cleaners was going to be a stretch, but the £150 extra we’ve been quoted for the professional carpet cleaning service is just too much.

Any thoughts would be very appreciated, thank you.
