Commercial window fitting cost per window

I own a small shop with a flat above and the front windows all need replacing. Do fitters price commercial work differently to domestic, and what should I budget per window?

"Depending on the location and accessibility to the windows, if permits are required, skips, etc, I would guess without seeing anything that you would be best to estimate approximately £700-£1000 per window. Again that's a complete guesstimate without seeing any pictures etc."

"The cost of installing windows remains the same whether the installation is carried out at a domestic or commercial property.

However, additional charges may apply where enhanced safety measures, specialist access equipment, additional labour requirements, or other site-specific requirements are necessary to complete the installation safely and in accordance with current regulations.

Any additional costs arising from requirements imposed by local authorities, planning permissions, building regulations, or other third-party approvals will be identified and agreed with the customer prior to any additional works being undertaken."

"Windows and accessibility are very different. The only way is to have a window repair specialist come and inspect them and give you a price"

"Depending on the size of the windows and depending on the style and how many openers you have and what type of glass.
They can range from different prices ."

"No , it still falls under domestic as the windows installed are standers compared to a shopfront where safety is a concern , the installation will be the same but safety measures will need to be put in place as it’s a shopfront all windows can be finnished from inside depending on the standers of fitter ."
