Some cities have organised tool libraries where you can pay a refundable deposit and borrow tools to complete your DIY projects. If you haven’t got an organised tool library, you might find others on your own road who have the drill bit you are missing or even the circular saw which you need as a one-off. Get in touch and share your tools and your skills.
Social media might be of help if there is a Facebook page in your neighbourhood or postcode.
