Screwfix

Despite being part of the same parent company as B&Q this place actually has what you want to do the job right.
You can either turn up and flick through the catalogues (they have quite a few
different ones), download the catalogues on your mobile device or do what I do and browse/​order on line after reading the reviews.
If placing an online order you quickly get a text to advise the staff in store have your order ready and it’s a quick drive round and there you are.
The staff are great and often help customers
whether they are trade or DIY with whatever queries they have and are happy to compare items or I’ve seen some customers bring things in to make sure they are buying the right items/​parts for the job.
There are a few items out on display in the store, usually plumbing, safety clothing and general decorating items that you often forget about or are handy to have for «spares» for those emergency jobs that happen when you don’t expect (and every DIY store is shut).
