How much approved plumbing work is sitting in your patch right now?
Every approved extension and loft conversion near you is public data in a council portal - and most need a plumber who hasn't been chosen yet. Move the sliders and see the size of the work you never hear about.

What this means for you
The number that matters here isn't the pipeline - it's who gets to those homeowners first. Approved applications are public data, sitting in council portals for weeks before the skip arrives. Most plumbers never look; the builder's "usual plumber" gets the work by default. A letter that lands the week the approval goes through puts you in front of the homeowner before anyone is quoting. The maths above assumes you only win 5 in every 100 you contact - the edge comes from being the only one contacting them at all.
Maths: approvals × 60% plumbing-relevant (new bathroom, en-suite, rads, boiler move) × your job value, annualised. Capture assumes you win 5 in every 100 sites contacted.

Common questions
How accurate is the planning leads calculator?
It's an honest estimate built on public data patterns: your local approval volume, a 60% plumbing-relevance rate for residential extensions and conversions, and a deliberately pessimistic win rate for sites you contact first. The exact figure varies by patch - the shape of the number doesn't.
Where does the approvals-per-month number come from?
Your local council publishes every application and decision in its planning portal. A typical UK local authority approves anywhere from a handful to over a hundred residential applications a month depending on the area. If you don't know your number, leave the default - or look at your council's weekly planning list and count the extensions.
Why are planning-led jobs worth more than normal callouts?
Because an approved extension or loft conversion isn't a leak or a tap swap - it's a new bathroom or en-suite, first and second fix, extra rads, sometimes a boiler upgrade. That's why the job value slider starts at £500 rather than £50.
Why does having no website halve the capture estimate?
The first thing a homeowner does with a letter from a plumber is Google the name on it. If nothing comes up, most won't reply - the letter did its job but the follow-through failed. A basic professional site roughly doubles the response you keep.
