There are different types of economics jobs and different Economics degrees will equip you more or less for these jobs.
There are jobs that are heavily mathematical, for example in some areas of finance, insurance, pensions, plus more niche areas in transport, health, energy, etc., as well as some jobs in academia and consultancy. Big data and data mining, while it has generated more jobs in statistics, has also opened up demand for people who can do 'hard maths' in sectors where there previously wasn't much demand, the obvious example being advertising and communications. These kinds of jobs often involve day-to-day application of high maths and economic modelling in areas such as forecasting, planning, risk management and some policy-making. To do these jobs, you really need to be a very competent all-round mathematician and employers will not be looking for any person with an economics degree. The kinds of courses that prepare people for these jobs are the ones that usually require A Level maths and prefer further maths as well.
Then there are jobs that don't really require you to be a high level mathematician, but they do require you to be a very competent statistician. These are jobs where you are still doing maths, but you are dealing more in applied maths and data interpretation. There are a lot of economics jobs that fall in to this category and it's a growth area generally, although there are a lot of not especially well-paid jobs in this area (compared to the average salaries of economics graduates). Some employers in this area would just want someone with an economics degree, but more likely, they would want to assure themselves that the person had some confidence and experience with maths, as evidenced through their having taken maths / stats-related economics modules and/or having A Level maths.
Finally, there are economics jobs that don't really involve a lot of doing maths. These jobs would include some areas of management and business functions more generally, some parts of investment banking, technical writing, some policy-related areas and other jobs where you are working predominantly at a strategic, rather than a technical, level and your job primarily requires you to interpret data, to understand it and to be able to communicate and apply that understanding. For these jobs, employers would just want an economics degree (or often just any degree) and economics degrees with a strong applied focus or those that allow you to focus on things like economic policy, history, social statistics and so on would be a good choice.
For universities, the top tier of universities for economics - Cambridge, LSE, UCL and Warwick - all have highly mathematical courses. This reflects something of a schism in the academic economics world. You will find some top economists who are very strongly opposed to the BA Economics degrees even being allowed to call themselves an economics course because the maths content is so low and what they do is not 'real economics'. The highest ranked courses require A Level Maths and people with only A Level Maths rather than Further Maths have extra classes to bring them up to the standard of maths required. These courses prepare people well for the highly mathematical jobs and would not be a good choice for someone who doesn't particularly likely maths or have a good grounding in it.
There are, however, universities that are highly ranked universities generally, rather than specifically being powerhouses in economics, that have a lower maths content to their economics degrees. Durham economics is a good example of a course that is notoriously low on maths content but very strong on theory and application of economics and its graduates are very sought after for the interpreting and communicating-type jobs. Leeds has an excellent reputation in applied economics. Some of the Business School-based economics departments also have specialist courses in Business Economics, Industrial Economics or economics courses with a very strong business focus which tend to have less mathematical content, e.g. Nottingham, Lancaster, Cardiff.
The ones I would really avoid are the pseudo-mathematical courses that appear to offer a lot of maths but when you properly look at it, it is really low level stuff. These are the worst of all worlds, because you waste your time doing basic maths that will not be of interest to employers who want proper mathematical skills, and you could better spend this time doing the kinds of things that will be attractive to employers who want people who are able to put economics in a broader context.
