Thanks for your response and many apologies for my typo's
I am afraid the fact you rent someone which provides more than a hotel of B & B but is deemed to be temporary is still not making it an allowable expense s its not incurred so you can can undertake your job solely, it provides a "home" setting in a way that a hotel or B & B would not - and that's why its not allowable
If the taxi fares are just from the airport to work then I would then state these are allowable - but not from your rented accommodation to work

Does the taxis in the UK from home to the airport to take the flight to Spain can be expensed?
Probably not as I would assume the train would be cheaper or driving and paying for car park? And you then go on and ask
can the car park at the airport in the UK be expensed? You cannot have taxi fares and car park fares ????
Also can the train fares from the home in the UK to the airport to take the flights be expensed? Yes but not a taxi also -
HMRC may restrict the travel to and from the airports and associated costs unless your employment contract recognises that you do live in the UK but that all duties must be carried out in Spain thereby forcing you to have no choice but incur these initial expenses - you state that your contract states your work is taking place in the UK so really you need to get your employer to update your contract of employment and back date to from when this began
I also do not understand why your employer fails to cover any of your costs - this is usually indicative of what is a true employment related (or business) expense and what is not
