Running or capital cost?
Air-air heat pump gives a good range of control and efficiency when running, and give a cooling option too.
Electric convector heaters are cheap to buy - so short to medium term win in overall cost of buying+running.
What's the building spec? New build and highly insulated with good window orientation and good heat recovery ventilation probably won't need a lot of heat.
And what's the usage pattern going to be, 'office' as in a couple of hours twice a week? or full-on remote worker 40hour plus? So, regular stable heat or quick responsive warm-up?
Interesting challenge.

60s house extended in the last 20 years the office is in the new bit about 3m x 2.5m. west facing window so gets the sun around 11am ish, until late afternoon
Most days it would-be in use for 8hours as usually at least one of them is working from home
Reading online looks like an oil filler rad would be 50p per hour to run!

Heating load is heating load. Unless you can get a good tariff, then a certain amont of heat will cost a certain amount of electricity, regardless of the name on the heater.
Controlability, so you only use heat when the room is in use helps.
The only energy 'short-cut' is heat pump, where the heat output is greater than the electricity consumption.
Other thoughts. That oil filled rad running cost - that will vary according to the thermostat, and that will depend on heat losses from the room. 50p an hour sounds like 'on continuously' which would seldom, if ever be the case.
And, you mention not wanting to run the central heating? Gas is still a cheaper fuel. Can you get zone your heating to the office only? Or office, kitchen and bathroom. Might be the best deal?

I use a diesel heater in my garden office, maybe not exactly wife and daughter friendly unless you installed it outside and just ducted the heat in?
Zoning the heating could be an option but without seeing the pipes it would be impossible to say if it's going to be easy or a nightmare

It'd be nice to know if there were any flued blue-flame heaters out there, similar to the Deville that I have in the workshop , but smaller.....

You could always install the wife and daughter outside, and duct the heat out.....

I have never paid more than £100 for a second hand one,normally loads of them up for grabs on ebay and the like. They are really easy to fit and no electric supply needed either so handy when there is a power cut.

Our office is a new build above the garage. We have a combined heat pump / air conditioner for spring, summer and autumn which runs off a 16A spur, and a wood burner for winter.

In my experience, with two women (or more) together, just insulate the office very well, they will bring their own "Hot Air Vocall Heating System" with them.........

I was called to help in a small office block, heating system had been replaced with a low temp system and central BMS
Many, many complaints from the fairer sex that it was "too cold"
Bit of an investigation and it turns out they used to go in, touch the radiator and if it didn't burn them, they turned the thermostat on the wall up
New radiators did not get that hot, and the thermostat was now a sensor so they could not adjust it
My solution was to install mechanical thermostats in every office, that clicked when turned up
We did not tell the office workers these were not connected to anything, but the complaints immediately stopped once they regained the ability to turn it up

We had similar when we refurbed the offices at the factory, we fitted all new electric radiant panel heaters which the women immediately started turning up from the set temperature turning the place into a hot house, luckily the control panels had a "lock out" option so we reset the temp and used that

from cold they take some heating up a large room so you would need a timer to come on earlier to heat the room to standared for usage
quick heat is the diesel heater will warm up much faster
wood stove from cold will give fast heat once lit
rocket stove would be the same just less usage of wood but the heat will need to removed from the room as will get too much the same with a wood stove
Ah, the fairer sex and their comprehension of how thermostats work.
I find myself sitting in a particular establishment for a couple of hours a week opposite the thermostat, and constantly witness the following spectacle:
Lady 1 walks past and turns the thermostat to 30 degrees
Lady 2 walks past 10 minutes later and turns the thermostat down to 5 degrees
Lady 1 walks past 10 minutes later and turns the thermostat up to 30 degrees
Lady 2 walks past 10 minutes later and turns the thermostat down to 5 degrees
...repeats for the duration of my coffee and scone, regardless of the actual ambient temperature or time of year....
