London shelving quote, is this reasonable?

I’ve been quoted £700+ to supply and fit four custom shelves into an alcove in a bedroom.

Details:

•	4 shelves, made from MDF

•	Wrapped/veneered to colour-match existing IKEA wardrobes

•	Built into an alcove (so scribing to walls likely needed)

•	Quote includes measure, make, fit (no decorating beyond the veneer finish)

•	Straightforward shelves (not cabinets), but fitted flush and tidy

This feels a bit on the high side to me for MDF shelves, even in London, but I know labour and scribing can add up.

For people with experience (homeowners or trades):

Does £700+ sound reasonable for this scope in London?

What would you expect as a rough breakdown (materials vs labour), and what details should I check in the quote?

Happy to share rough dimensions if that helps. Cheers!
