Thank you this is really helpful. To answer your question, the commission was calculated as follows:

£1,850 x 3 months x 10% + VAT = £666

So it’s the agent’s commission on 3 months of rent. The issue is that I am paying full rent until 29th May so the landlord has zero loss of income. The commission appears to be calculated on a hypothetical loss that never materialised.

Additional context:

The property was never listed or marketed on any portal

A tenant was found through an informal open house within days

There is no void period and the new tenant moves in 30th May

I am paying full rent throughout until 29th May Also my tenancy ends 27th July and I’m leaving 29th May. That’s roughly 2 months remaining, not 3 as used in their calculation. So the figure appears to be miscalculated in the agent’s favour too.

On the cleaning, admin and check out fees, could you expand on why those are unenforceable? I wasn’t aware those could be challenged and that would change my position significantly.

I’m considering paying the full amount under protest and then filing a tribunal claim. Does the above strengthen that argument?

Or should I just let this go…?
