I had a heat pump installed by my landlord where it is now costing me almost £200 a month with Scottish Power .... I don’t feel I was a suitable candidate for the heat pump but they put it in anyway.

If you are not prepared to learn how to operate your heat pump then you were not a suitable candidate for one.  You'll have to put up with bigger bills and cooler bath water.  Hopefully the next tenant will do better.

I agree with @Reed_Richards, if you dont put the effort in to learn how to use it properly then it will cost you more than it needs to and you wont be comfortable either.

They do work, and they can be economical but they have to be used properly to get the best out of them

If you can tell us the make and model of heat pump, we can probably give you some help with finding the settings.

This would be great thank you. It seems to be a Daikin Altherma 3m. Some of my settings are locked by the installer.

Do you have the Madoka controler?

If you do, the manual is probably this one:

There are instructions in there (pages 5 & 6) on how to set the hot water temperature separately to the heating temperature.

Have you got this controller or something different - https://www.bing.com/videos/riverview/relatedvideo?q=daikin+altherma+controller&mid=F18AED33FEBC689DE409F18AED33FEBC689DE409&FORM=VIRE

There are other Youtube videos as well as this one which show you how to tweak your settings

Just be a bit careful, decide what you want to change eg Hot water temperature and timings, Heating flow temperature and timings.

Write down the existing setting, so you can put it back if you don't get the desired effect. Also leave the system to settle down for a day or two to see what effect it has. If you turn down your flow temps it will take some time for the effects to be felt.

You could also check your energy consumption to see what effect is has - hopefully reducing it

to get access to the installer mode see here -

Depending on what access controllers you have, there could be a way of getting into installer settings. My hot water was set to reheat and I was able to turn this option off by getting into the installer settings.

No I have a switchee I think

If you put up a few photos of your controller, thermostat and any other stuff that sits around the hot water tank - things like thermostats, control valves etc., someone may be able to help.

Over the years Daikin has had several different types of controller, installers have their own favourite thermostats, anything from an all singing and dancing Daikin Madoka, Hive or similar down to cheap and nasty. Even hot water cylinders come in a variety of sizes and configurations, some are pre-plumbed and others plumbed to the whim of the installer.

There really isn' twhat you might call a standard installation, everyone is a bit different but if we can see what sort of controls you've got then its a lot easier to give some help

I think a Switchee is "just" a smart thermostat, not a heat pump controller?

https://switchee.com/

I can't see any way to control the hot water temoperature from one of tthose. Is there another controller eg. attached to your hot water tank?

I think you are right, its just a smart thermostat which just turns the boiler on and off when it calls for heat, likewise, the hotwater control probably just operates the diverter valve. Not much different to running a gas boiler.

In fact its a bit like controlling the speed of your car using the ignition switch to turn the engine on and off - pretty crude.

The heatpump controller is the device that controls the flow and hot water temperatures and that's what needs to be adjusted to optimise the heating

The Switchee looks like it has a facility to report heating and hot water usage back to a central point (not sure why a housing association would want to do that though) I know what I'd do if I had one.
