Louise let me be honest here because you don't want to get into a career that is going to make you miserable! Consulting firms send their staff where the money is, ie. to wherever their clients are based. So apart from consultants that only advise investment banks (ie. clients in the City of London) it is very unlikely that you will not find yourself on the road a fair amount. And even consultancies whose clients are investment banks will still find their consultants need to go to Frankfurt, New York, etc. from time to time.<br><br>
It is true that some firms make more of an effort than others to achieve a "work / life balance" - and it's also true that the more seniority you get the more you will be able to influence how much you are away from home. But the bottom line is that you will be sent where the money is and I don't think any consultancy could promise you a lifestyle where you are based in one place with no need for travel.
An alternative you could look at is joining the internal consulting team of a major FTSE company. Many of them have such teams and the travel involved is obviously limited to places where the company actually has offices. This doesn't mean zero travel, but generally a lot less travel than with a consulting firm. These types of roles aren't always viewed as being so "glamourous" as joining a McKinsey or Accenture - but then if the glamour of regularly travelling doesn't appeal to you this probably isn't such a concern.<br><br>
Hope that helps and good luck with making the right choice. Tony
