Roughly? £35 was worth about £35. I would guess that you're actually asking what £35 in 2017 money was worth in the Victorian period. And the answer is... there is no answer. Queen Victoria reigned from 1837 to 1901. During that time the world economy (and the British economy) underwent huge changes. There were also huge changes in technology in that time. Not as huge as between say *19*37 and 2001, but certainly ones which affected the real cost of things such as transport and manufactured goods. This was the time when the Industrial Revolution was exploding. Consequently what you could buy in 1837 and 1901, and how much of your wage it would cost you, were two completely different things. But even if you pick a convenient waypoint - say 1870 - the cost of things cannot be comfortably compared to now. The cost of furniture, for instance, would probably have taken a greater percentage of someone's wage then than it would now. This page gives you some idea of what wages were like in the mid-1860's: http://www.victorianweb.org/economics/wages2.html If you work out £35 as a proportion of some of the salaries shown, and compare them to modern salaries, then you will have AN answer... though it may not be a particularly relevant one for the reasons that I've given above.

It's hard to say, because some things (such as services) were cheaper than they are today, while other things (such as manufactured goods) were much more expensive. There was also a far greater disparity between the rich and poor. For example, a labourer might only earn £10 a year, while a wealthy person might spend that amount on a pair of gloves. This can give you some idea about wages and costs in the Victorian era: http://www.victorianweb.org/economics/wages2.html

35 a year? 35 a week? 35 a month?

All such comparisons are imprecise, but according to this online calculator, http://inflation.stephenmorley.org £35 in 1837 was approximately equivalent to £3,640 in 2016 £35 in 1901 was approximately equivalent to £3,885 in 2016 Incomes in the Victorian era were often stated as annual income. I once looked into this for the United States and the numbers were similar--I was looking at 1872 or thereabouts and roughly you multiplied by 100 to get the modern equivalent. Notice that an average inflation rate of just 3%/year will result in multiplying prices by a factor of 100 in just 156 years. (1.03^156 = 100.6), so this only represents about a 3% rate of inflation.
