INCONSIDERATE business and behaviour

Stop parking your oversized trucks on our residential roads, hence forcing us to park 3 roads away when you have your premisses. We had our rubbish and refuse not being collected due to them not being able to come down our road, as your OVERSIZED truck is making driving down our road difficult. Be a considerate neighbour and business.

Materials overpriced

This building merchants is seriously stealing money from customers pocket. I bought 1.5mm cable from here for £40. My builder contacted me the next day amd ask me to buy more since the one I bought has finished. I stop by screwfix and it was £26 there. I got curious so I check at toolstation and it was £24.98. I call GNK to complain and I was told by the member of staff who answered the phone that because they are a small business they price their products high because they do not buy huge quantities like screwfix and other outlets. To charge almost double the price for an item is a complete rip off. I can understand a small difference in price but not a £14 difference. They most likely are buying from store like screwfix and toolsStation to resell. I am disgusted by their behaviour given that I've spent more than £5000 in the last month buying from them.

Please avoid this merchants. Always double check prices with other stores before buying.
