Landlord and Heating Ussue

[FANTINE2]

With permit, my daughter’s landlord entered the property with a gas engineer to carry out a gas check. Both my daughter and her house mate were out.
Unfortunately., the heating has been left on for a full 24 hrs. Given tye present situation regarding bills, they can hardly afford to lose this money.
Landlord has offered them£10.
They feel this is unreasonable. Do they have any legal rights?

With permission.

It's probably about right - it's probably £10 to heat the place for a day.

they had a nice toasty home to come back to though eh?

I don't think £10 will cover it. I left my heating on 18 degrees overnight by accident, last night. I normally turn it off overnight. It racked up £9 on the meter for 7 hours.

Mine was on for 24h yesterday and cost me £6.

If they have a smart meter, they can work out the excess used pretty easily.

How high was it set to? After initially raising the temperature it would only click on as needed. £10 would likely cover it.

They don’t have a room thermostat, but according to the Landlord, it is incorporated in to the boiler.

The house was extremely warm when they got back.

Hmmm I would go back and ask for £20 as it was too warm for £10 to cover it and then they could compromise on £15?

They will have benefitted from the house being warmed up properly at least.

Sounds reasonable to me

What’s their normal bill and how much do they normally have the heating on for? It would be reasonable to ask for excess, but he may have already offered that. It sounds like he’s pretty reasonable if his response to being notified was to offer compensation and it seems unlikely, even if he refused to increase, that it would be sufficient to reasonably warrant even small claims. So is he dodgy in other ways? Is there a reason your first thought is to ascertain the legal position?
