Help me sort out a tenant kitchen conundrum

[Crafters]

I am letting out a small flat. It has a built in gas hob in the work surface and a microwave oven. A tenant moved in a month ago and part of the terms were that they wanted an oven fitting within 3 weeks. The property is fully managed. I went to John Lewis before they moved on and ordered an oven to be delivered and gave the property manager the delivery date. I also informed the property manager of the fitted hob and said an engineer/ carpenter would need to go round to remove that and fit the new oven. This is all on emails. I gave the manager all the order details.

The property manager called John Lewis and changed the order for another date to suit the tenant (fine). John Lewis tried to make the delivery for the new slot and neither the tenant or the manager was there to receive it so it went back and was a failed delivery (I don't live near the property).

In the meantime the property manager called me and said "oh there's a gas hob there we can't fit the oven!" I was baffled as we had had this detailed conversation over email about the issue.

The cost of the oven has now been refunded to me by John Lewis as the property manager told them the appliance was not suitable as it had to be integrated

AIBU to just buy a decent table top oven and forget trying to fit a full new one when there is a fully working 4 ring gas hob and removing that and fitting a new oven in its place has become a total nightmare?

Why not disconnect the hob and buy a stand alone oven with hob.

What where the arrangements before you purchased the flat? Is it a luxury apartment you have bought - in which case you need the oven fitting into the carcass of the cabinets and then you need a leccy to connect to the power. Sounds like a lot of arsing about if it is a 'basic' flat.

You need a housing carcass for an oven, it can't just go in a normal cupboard. And presumably you need the wiring.

If it's just an electric oven most don't need dedicated wiring.

I used to live there. It's a normal kitchen but with a small surface microwave and oven combined and a gas hob. I can't just disconnect the hob and put a cooker in as there would be no space for an oven without cutting out the hob.

You'd need a plumber to sort out the gas as well. Gas hobs normally have a fixed gas connection rather than a bayonet connection like you'd have with a cooker.

Ah no, separate appliance, my mistake, @Viviennemary
