You can buy an attachment for many phones that offers good demo-quality audio for around £100. There tend to be more offerings for iPhone, something like this or maybe this would work well. THere's also something like this that would work on any phone, and would give better results than just the mic on your phone.
There are also a few good recorders out there in your price range that would give you good quality like the Zoom H1 or the Tascam DR-05. Both Tascam and Zoom have a range of options for digital recorders, and some of the Zooms also function as an audio interface that you can plug into the computer. I have the Zoom H6, which is outside your budget but a fantastic recorder for the money.
One word of warning, don't be suckered in by cheaper alternatives for mics or recording equipment. You get what you pay for, and anything under about £50 in either department isn't going to be too much better than the mic on your smartphone.
