Use what you already have; borrow when the job happens once or twice a year and a return date fits the week; buy used when you will need the thing more often than that, or cannot get it back on time. Frequency decides it before price does. Library of Things rents 45 or more items from 22 locations and caps a borrower at four Things at once or £1,000 of replacement value, which suits an occasional job and not a weekly one. The condition that moves the answer is the calendar: a loan you cannot return by closing time on the agreed date is not the cheaper option.
Three routes, three different obligations
The three routes differ on what they suit, what they cost and what you owe when the job is finished, so compare them on all three rather than on the price alone.

| Route | Suits | What it costs | What you owe afterwards |
|---|---|---|---|
| What you already have | A job something on hand does properly | Nothing beyond preparation | Put it back; nothing changes |
| Borrowing | One or two uses a year, within a fixed window | A joining fee from £1 and a daily rate | Return it clean, complete and on time, or pay 1.5 times the daily rate per day late |
| Buying used | More than a few uses a year, or an open-ended need | Price, collection and storage | Keep it working, and decide its next owner |
Figures: Library of Things' terms of borrowing.
The obligations come from Library of Things' terms of borrowing, which also state the rules that catch people out: members must be 18 or over, reservations can be cancelled free until 9am the day before, damage must be reported immediately, and an item more than 24 hours overdue without agreement is treated as a non-return and charged at full replacement cost. The same terms note that reasonable wear and tear is not charged for when it is reported honestly.
Owning is not automatically the wasteful answer, and borrowing is not automatically the green one. A borrowed item collected by car across a city has a return journey attached to it, and the return journey belongs in the comparison. When the decision is between keeping a working thing and replacing it with a better one, the arithmetic changes shape again, which is why keeping a device longer is not one simple number.
Example: a wallpaper stripper for one weekend
An example with the scheme's own rules. Two people plan to strip one room over a Saturday and Sunday. One measures the walls and confirms the job fits two days; the other checks the nearest kiosk, reserves the stripper and notes the return date and the closing time it has to be back by. Reserving and collecting can happen on the same day, so the decision does not need a week's notice.
Run the failure case before booking. A two-day hire returned two days late costs the equivalent of five days' rate under the scheme's rule: two days hired, plus 1.5 times the daily rate for each of the two late days. At that point a used stripper starts to compete, and the honest test is whether the room is the only room. One weekend a year is a loan; a house being stripped one room at a time over a year is a purchase.
What a used purchase now comes with
A second-hand electrical item is a better bet than it was, because the spare parts behind it are now regulated for some products. Under the ecodesign rules that applied to smartphones, cordless phones and tablets from 20 June 2025, manufacturers must supply key spare parts within 5 to 10 working days and for at least 7 years after the model stops being sold in the EU, batteries must survive at least 800 charge cycles while keeping 80% of their capacity, and operating system updates must be available for at least 5 years after the last unit is sold. Before buying used, check how long the model has been off the market, because that clock started then.
Ask the seller the two things a listing usually leaves out: which parts are included, and what it does when it fails. The EEA counted 20.6 kg of electrical and electronic goods put on the EU market per person in 2017, with 10.4 million tonnes of electrical waste generated that year and around 44% of it collected, so a used purchase that stops working after a month has moved the problem rather than solved it.
Write the decision down in one line, with the reason: "borrowed, one weekend, returned Sunday" or "bought used, four jobs booked this year". That line is also what tells you whether the words on a product listing are doing any work, which is the same question as repairable, reusable and recyclable being different promises. If the answer was "borrow" and no scheme covers your street, the next step is a shared shelf of things to borrow.
