The toolkit

Three tools no other UK platform puts together.

Most sites either find you a builder or estimate a cost. Plotted does both — then shows you whether the project is financially worth it.

From the founder

Most renovation sites start with "here's a builder." I wanted to start somewhere more honest.

Before anyone picks up the phone, the question on every homeowner's mind is really "is this even worth doing?" That's the bit nobody else answers first — so that's where Plotted starts.

We're brand new, and I'm not going to pretend otherwise. Right now it's a small, hand-picked group of builders across Surrey and West London, and I'm personally getting to know every one of them myself before they go on the site.

If you're one of our first homeowners or builders — genuinely, thank you. You're helping build this from the ground up, and I'd love to hear what you think as we go.
