Buying materials in bulk saves money, but cable drums, copper pipe, and boxed fittings can quickly take over your garage. Wow Storage offers storage for electricians and plumbers across London and Hertfordshire, with secure container space for the stock behind your jobs.
Most of our sites offer 20 ft x 8 ft containers. Check the location page for the site you want to see what’s available, or browse all our units.
Roughly the size of 1.5 garages, with room for cable drums, consumer units, copper pipe lengths, fittings and boxed fixtures, kept organized and easy to find before a job.
Ealing, Harrow and Shoreditch also have stair-access units at a lower cost. These suit smaller stock such as boxed fittings, switches, sockets, valves and testing equipment.
Firms holding materials for several projects at once may suit our Acton warehouse storage, which has 300 and 500 sq ft ground-floor units.

We don’t insure your goods, so they must be insured before they come on site. You can arrange cover through Store Protect.
We can’t store flammable or combustible materials, chemicals, perishable food, or other hazardous items, so keep solvents, sealants, and fuel-based products elsewhere. See our Terms and Conditions for the full list.

Wow Storage has operated secure sites across London and Hertfordshire since 2015 – security is designed into every site from the start, not added on afterward.
Trade businesses don’t grow in a straight line, and storage needs to flex the same way. Units are rented monthly, so you can take more space ahead of a big job or busy season, subject to availability, without committing to a fixed unit year-round. Notice terms are in our Terms and Conditions.

Electrical and plumbing work uses a lot of stock, and bulk-buy savings only help if you have a dry place to store it. Here’s who typically ends up storing with us.
Cable drums, consumer units, trunking and testing equipment add up to a serious amount of stock. A container keeps it dry and organized between jobs.
Copper pipe, fittings, valves and bathroom fixtures take up space fast. A container gives you room to hold stock for several jobs.
Businesses covering both trades carry a wider range of materials and need clearly separated space for each, which a dedicated unit makes easier.
Boilers and cylinders bought ahead of installations need secure, dry storage until the job date.
Once a business wins larger contracts, materials arrive in volume before work starts. Somewhere central to hold them keeps the whole team supplied.
Looking for a general trade space? See our storage for tradespeople or storage for construction.
You don’t need to clutter your van or workshop with every tool and spare part. WOW Storage gives electricians and plumbers secure, flexible space to keep equipment, tools and supplies organised and ready for the next job.

Most units are on the ground floor, so cable drums and pipe lengths are loaded and unloaded at the door, with no lifts or long corridors.

Collect materials before a first job or return late after a long one. Site access is open 24/7, every day of the week.

Add more room as your workload grows, subject to availability, without a long lease.

Insulated and ventilated to keep condensation down. Each unit is lit, with power available for limited use.

Gated entry and 24-hour CCTV recording.

Business storage without the commitment of a warehouse. If you outgrow a container, there's Acton warehouse storage.
