"Buying this reducer saved having to buy a full £20+ fitting kit for a replacement kitchen stove extractor. Being able to buy specific "bits" of kit through "Screwfix" enables you to save £££ over the year and often recycle old parts and equipment."
"Excellent service click and collect. However, I encountered log in problems but a quick telephone call to a very helpful lady - took my order and I was able to collect from my local branch within the hour. Many thanks again."
