PlanWatch Demand Radar · for plumbers & bathroom fitters

Plumbing and bathroom leads, straight off the planning register.

Bathrooms, en-suites and utility rooms, named in the application — plus every build that adds one. Some applications name the work outright: a bathroom, an en-suite, a wet room, a utility. The rest imply it. A loft conversion usually gains an en-suite, a kitchen extension moves the sink and often the boiler, and a new dwelling is a full installation from scratch. All of it is dated on the register before the homeowner starts looking.

11,020 matching applications hit the UK register in the last 30 days, from the 376 council registers we read daily — filtered down to just the councils or postcode areas you cover.

Enter a full postcode to search a 5 km business radius, or name the councils or postcode districts you cover. We will run the last 90 days of the public register through the same trigger model your batches use and tell you how much matching demand is sitting in it right now.

Counts only. High and medium confidence matches, deduplicated to one line per application. The site addresses, planning references and per-row reasoning are what a subscription buys.

Why the register

Why the register beats every other lead source

  1. Bathroom work is bought on recommendation, and you are only recommended if you were visible at the right week.

  2. Merchant showrooms catch the customer late, after two firms have already quoted.

  3. Reactive leaks and breakdowns are unplannable; consented projects are not.

A fitted bathroom or en-suite runs into thousands; a new dwelling or a whole-house renovation is a far bigger ticket, and both repeat through the maintenance years after.

The matching table

Exactly what we match for plumbers & bathroom fitters

This is the real matching table, not marketing. Every lead row you receive shows its trigger, demand window and confidence — and the reasoning is printed on the row so you can sanity-check every address before it's mailed.

TriggerExample from the registerDemand windowConfidenceWhy it matters to you
Bathroom / en-suite / wet room Single storey rear extension to form utility room and shower room now – 4 months high the application names the bathroom/en-suite/utility work itself
Loft conversion / dormer Loft conversion with rear dormer and 3 no. rooflights 2 – 5 months medium most loft conversions add an en-suite, but not all — hence medium
Kitchen extension / open-plan kitchen Single storey rear extension to form open plan kitchen diner 2 – 5 months high sink, appliances and often the boiler move with the kitchen
Two-storey / first-floor extension Two storey side extension and single storey rear extension 3 – 6 months medium first-floor extensions commonly add a bathroom or en-suite — hence medium
Single-storey extension Householder Planning Application - Single storey rear and side extension 2 – 5 months medium many single-storey extensions add a utility or WC — hence medium

Named bathroom work is actionable immediately (0–4 months); extension and loft plumbing lands 2–6 months after consent; new dwellings 4–10 months. Demand windows are measured from the expected decision date. Refused and withdrawn applications are dropped automatically. How the demand windows are built →

Questions

Straight answers

Do you separate bathroom fitters from general plumbers?

No — it is one list, but every row prints the trigger that put it there. Rows that came from explicit bathroom, en-suite, wet-room or utility wording are marked as such, so a bathroom specialist can work those first and leave the rest.

Demand Radar or the Business plan — which one do I need?

Same price, different product. Demand Radar posts you an addressed mailing list every month for one trade in your patch, with exclusive cover: it is for firms that write to homes. The Business plan is alerts, keyword rules, a dashboard and an API across any councils you name, with no addresses: it is for firms that want to know within hours of something reaching the register and contact people their own way. If you want letters through doors, Radar. If you want a feed, Business.

Where does the data come from?

Published planning applications from the UK planning register — planning.data.gov.uk plus direct council sources, covering 378 local authorities. That register is public information. What you pay for is the trade-trigger matching, the demand-window timing, the deduplication and the suppression, not the raw fact of the applications.

How far back does the first list go?

There is no fixed cut-off date. We look back across the register and keep only the applications whose buying window for your trade is still upcoming, open or closing. In practice that means most of a first list is the last six months of live projects, plus a tail of larger builds from further back that are only now reaching your stage. Anything finished or already past its window is dropped, and each household appears once and is never sent to you twice — as is anything refused or withdrawn, unless your trade is architects and planning consultants, where a stalled application is the whole point. Whether that first list comes out bigger or smaller than the 90-day figure on the patch checker depends on how long your trade's buying window is, and it goes both ways. A long-window trade — glazing, kitchens, flooring — gets a much bigger first list, because consents from six or twelve months back are only now reaching its stage. A fast-window trade like skip hire or demolition gets a smaller one, because a nought-to-three-month window has already closed on a good share of what the checker counted. Either way later months are smaller than the first: they carry new applications only.

Why postal outreach only? Can I get phone numbers?

No, and that is deliberate. The register is published for planning transparency, not to build a calling list. We store no applicant names, so there is nothing to phone: letters are addressed to "The Owner/Occupier" at the property. Mail only — no email, no SMS, no cold calls — and every letter should cite the planning reference and carry an opt-out address. Firms that want a dialler list are not a fit for this product.

How many other PlanWatch letters will the same household get?

One planning application can be work for several trades, so we limit how many of our subscribers can post the same household in the same month. A shared-cover subscriber may see a few addresses held back until the next month, and the dashboard and batch email say how many. Exclusive cover is never held back by that limit: an exclusive subscriber always gets every address in their patch.

How does exclusivity work?

One subscriber per trade, per patch. The check runs before you pay: if another firm in your trade already holds those councils or postcode areas, we tell you at signup and take no money. Exclusivity is scoped to your trade only — a roofer and a window company can both hold the same town without clashing.

Can I cancel?

Yes. Billing is monthly and you can cancel at any time; cover runs to the end of the month you have paid for, then the patch is released for someone else. There is no minimum term and no contract to exit.

What happens when I sign up today?

You go straight to secure checkout, and your first list is generated within 24 hours of activation rather than a month later. That first list is not a snapshot of the last few weeks: it carries every live application in your patch whose buying window for your trade is still upcoming, open or closing, which in practice is most of the last six months plus some larger builds from further back that are only now reaching your stage. Finished jobs are dropped and each address appears once. Refused and withdrawn applications are dropped too for every building trade — with one deliberate exception: on the architects and planning consultants list they ARE the list, because a refusal is the moment a household discovers it needs drawings. After that a fresh list arrives every month covering new applications only, so it will be smaller than the first. If your patch turns out to be thinner than you expected in that first month, tell us and we will sort it out.
