Cost of the item is £550 and it's a jacket. I haven't ordered or made an account with them before.

Although It's best to have a matured account with at least one legit purchase, It doesn't mean you cannot SE on a fresh account.

Do remember that as far as the company Is concerned, the SE Is a legit claim. If you legitimately submitted a claim (for example) on a package that didn't arrive, you'd have very little Issues In obtaining a replacement/refund. An SE Is no different.

What method are you planning to use?

I see what you're saying there. I am planning to use the partial method. What other item is best to ship with a jacket?

The other Item Is Irrelevant.

If the jacket Is rather heavy and registers a significant weight, they'll simply deduct It off the total weight of the consignment. As such, If there's no variance and the "dispatched" weight matches the "delivery" weight, then the jacket Is deemed as received hence the SE will fail.

When using the partial method, always take the Item's weight Into consideration. Some companies don't bother checking but If they do, your SE will not succeed.
