Hopecraft · Warwickshire pilot

The maths of a qualified enquiry.

Hopecraft is a tool a homeowner uses before they ring anybody: they type their address, get a true 3D model of their actual house, design the extension on it, and see honest costs and the planning position — at their own kitchen table. What reaches a builder afterwards is a brief he can price from, from someone who has already faced the numbers — and it goes to one builder, not to a list.

Here are six ways to count what that's worth. Same story each time, measured differently.

The base scenario, used throughout A builder gets 10 extension enquiries a month; each quote costs ~3 hours including the site visit; 7 were never real (daydreamers, sticker shock, planning surprises), 2 are borderline (real intent, wrong expectations), 1 becomes a job. These are rules of thumb, not survey data — swap in your own numbers and the arithmetic becomes yours, not ours.

01The funnel, before and after

Today the builder can't tell which enquiry is which until he's driven out, measured up and written a number — so all ten get the hours, and seven were never real. With Hopecraft the sorting happens before the phone rings: the daydreamers meet a realistic cost band at home and quietly drop out. Same ten households, same job — but the dead seven never cost him an evening.

02The time ledger

Quoting the never-real seven costs 21 of the month's 30 quoting hours — usually evenings and weekends, and priced into every job he does win. At a £40/hour charge-out equivalent, dead quotes burn about £840 a month, over £10,000 a year, of billable-grade time finding out that nothing was there.

03Same hours, more jobs

Flip it round: hold the quoting time fixed at 30 hours a month and ask what those hours buy. Today: ten quotes, three genuine, one job. Fill the same 30 hours with pre-qualified enquiries only — every one real, dimensioned, budget stated — and they buy ten quotes, all genuine: about three jobs at the same one-in-three win rate. The diary didn't change; what filled it did.

04The site-visit lens

Measure by trips. Ten visits a month, one becomes a job: a 10% strike rate, with fuel and mornings carrying the other nine. Qualified up front, he visits only enquiries that survived the cost band — and each visit starts half-finished, because the dimensions, the wall, the planning flags and the budget arrived on paper first.

05The borderline rescue

The strongest version, because it grows the top line rather than defending the bottom. The two borderline enquiries were real intent with wrong expectations — a budget out by half, or a planning surprise waiting at week six. The tool repairs rather than merely filters: the honest cost band resets the budget before the visit, and the permitted-development flag turns "the council said no" into a known step. If one of the two becomes quotable, the job count doubles without a single new enquiry existing, and with no extra marketing spend during the pilot.

06The year view

Small monthly numbers hide the annual truth. Seven dead quotes a month is 84 a year; at three hours each that's 252 hours — more than a full working month, every year, spent proving that enquiries weren't real. Give a builder his month back and he can build with it, quote with it, or go home with it. All three beat the current use.

07Set your own numbers

Every number above is illustrative and says so. If your real numbers are different — and they will be — that's exactly the conversation worth having. Drag these to yours:

7 wasted trips a month — 21 hours monthly, 252 a year, spent discovering an enquiry wasn't real.
The same hours refilled with pre-qualified enquiries become ≈28 additional won jobs a year at that win rate.
