How much should I haggle on casement windows?

[Micaela64]

I'm wanting some Casement Windows - Double glazed with acoustic glass for extra soundproofing. The window is quite large and it will require the company to use scaffolding and apply for pavement license.

They have quoted me £2685 for the job. I was wondering how much I should haggle to try and get it lower?

Many thanks

Why would you assume you should haggle with a company that provides a professional service?

If you feel the quote is high, get more quotes. Then compare them.

I've done it before with other companies. Or many will offer a price, then if you say you can't afford it they miraculously give you a lower offer. Hillary Blinds for example.

Seems a lot for 1 window
Get more quotes
It's only the national companies that haggle... and that's because they take the piss in the first place so they can do their... sign up right now and get 50% off nonsense
Local companies generally give their best price... maybe a bot of wiggle room like 50 or 100 pounds

Some large companies quote high purely in order to be able to offer you a large "discount" so you think you're getting a bargain. It's a con. Get a comparison quote from a local firm. You may well find it's cheaper anyway.
