HFS, it's 1200kg.
And Daan I live on a hill and have to go down that and then another hill to get out of my road .
1200kg isn't too porky then. Certainly not by modern car standards. The Mazda weighed more or less the same as the Fiesta I had previous to it (950kg~), and while it also had wider (and less appropriate) tyres, I found it easier to drive in the snow because of the better balance.
As for hills,
daan pretty much covers it. You have to be exceedingly careful going up hill, because FR cars don't tend to have as much traction on snow. The benefit a front-drive car, or even a rear-engined car has in snow, is having a bit more weight on the driven wheels.
What you may find going up hill is that as soon as the wheels start to spin, you're screwed. Spinning wheels means having to back off to regain traction, and doing so loses momentum. Then you're going more slowly... and the wheels start spinning again, so you slow down further, and eventually after doing that a few times you're at a standstill, unable to get up the hill. Or perhaps sliding backwards down it, which is worse.
Of course, if you throw some winter tyres on it, or even get "tyre socks", then that'll solve some of the problems. Since you've already said winter tyres won't be worth the investment, it may just be worth buying some tyre socks,
which seem to cost about £30.
The only issue I anticipate with them is that in mixed conditions they'd tear up pretty quickly. Probably fine for completely snowy roads, but you'd need to remove them again on wet tarmac.
