At the risk of belabouring the point, but both of your salary options sound really low. You might be trying to optimize around a local maximum. Try taking a step back to explore what the broader landscape looks like. How much does somebody with your level of experience make in the UK? In the big cities? top and bottom of the range? etc. Knowing your real worth can help you structure your salary negotiations a lot better. Most people work on the basis of incremental advances (e.g. I want 3% more), but that makes no sense if you are fundamentally in the wrong range.
Google gave me this:
http://www.jobadswatch.co.uk/jobstats/trends/salaryI can't find anything on the list as low as your current options (beyond grad students...).
I don't think 24k is very high, but I'd be wary of using tools like this to compare salaries, for a couple of reasons:
1. That list is for IT jobs, which as I understand is not exactly what you do
2. London will blow anything else out of the water in IT, and hugely skew the stats (it's also where lots of the jobs are). This is because of financial software. This doesn't seem to be the case for electronics, aside from the normal London weighting.
That being said, making sure you know what you should be on in the wider context should definitely a priority so I would agree with the main thrust of Helge's post. Don't just go for another job with a similar title and similar salary.
Also make sure you have a good handle on the actual difference it will make. Assuming you have a student loan, you will get 60% of any increase from either a pay rise or new job (20% tax, 11% NI, 9% loan), that's £300 per month. It'll be less if the new job's pension is contributory or you have taxable benefits like healthcare. I have absolutely no doubt your cost of living will be higher daan saaf, I have lived in several northern cities including Nottingham, and now live in Cambridgeshire which is probably roughly comparable to Guildford.
If it turns out that the short term gain is going to be negligible after moving jobs (if it costs you an extra £250 a month in rent and £50 in council tax that wipes out your entire pay increase), you should consider the long term ones. Bear in mind that you are currently being paid a lot in benefits relative to your salary: your final salary pension (!) and master's course principally. Is the master's going to increase your medium term earning potential? Are there more opportunities to move to a new job again in the future in the midlands or in guildford?
On the subject of locations, Cambridge is very "techie" and has a fair bit of electrical engineering type places because there are lots of commercial R&D functions here. It may be worth a look for jobs? A place with a high concentration of potential employers helps in terms of both stability and career opportunity. You could say the same about London, but of course the benefits aren't quite as big as would be the case for finance or IT.
