i would email the boss to say that you are "happy to pay the bill minus the amount for the product not used plus enough to cover the extra product used" (include the individual amounts, if known) and quote the final amount that you expect to pay for the job "as soon as the scratches are repaired" best of luck and hope you're happy with the final results

Thanks for the replies. I think regardless ill need to paint the posts a darker colour, so you arent seeing the red colour through the boxing. Any advice on the painting would be appreciated :)

In NSW for example electric storage can no longer be used. Heat Pump HWS are quite efficient. Gas instantaneous HWS are probably the most popular if natural gas is available. Very efficient as they only run when a hot water tap is turned on as well as being quite cheap to buy and install. The choices all depend of what you're ultimately requiring and whats available. Natural gas available, wanting to be environmentally friendly, solar power to run a HWS, etc.. Solar HWS... Lot of choices depends on your circumstances and budget.

When selecting windows it’s a good idea to think about how they perform thermally. The frames influence this as well as the glazing. Timber, uPVC and thermally broken aluminium frames are lower conductors of heat and cool than regular aluminium or steel frames, but they do come at a cost premium. Timber frames also require much more maintenance. And, of course, aesthetics come into play. The windows you select will affect your NATHERS or BASIX rating and will also affect your heating and cooling requirements.
