Recommend a supplier of tool chests and garage storage

[LunarOne]

My garage is triple-length but shaped like a long tapering triangle about 6 ft wide at the narrow end and maybe 12ft wide at the garage door end. I want to bring a car in to do an engine rebuild and free space on my driveway for another car. However, the garage is currently filled with random furniture and also lined with free-standing wooden shelving and surplus kitchen units that take up far too much space and aren't able to help me store tools efficiently. Some of the backs of the shelving units are coming away and the shelves themselves are made of low density MDF and suitable only for storing things like lawn treatments and bug spray. I'd like to replace some of them with purpose-built tool shelving that's more space efficient, so I can reorganise things and give me room to move around the car.

I've looked at:
Halfords: https://www.halfords.com/tools/storage/all-storage
SGS Engineering: https://www.sgs-engineering.com/garage-equipment/t...

Can you suggest other suppliers of garage tool storage and general storage? I don't want to do regular metal racking as I'd like it to be lockable. The only access to my garden is via the garage, and I have already caught light-fingered tradesmen thieving thanks to a wireless camera hidden in the garage.

Thanks!

The Sealey cabinets are decent enough, just got some for my garage.

Thank looks brilliant! Probably a bit too posh for me but I quite like the idea of old office furniture and hadn't thought to check Machine Mart.

Re: Costco - I just checked their website and it doesn't seem I'm eligible for membership. I'm currently freelance and don't work in any of the industries they list! Thanks for all the suggestions - keep them coming!
