Every household in your patch spending five figures on their home — and every new unit that will need selling.
Two things planning data tells an agent. A family extending or converting is improving to stay or to sell, and the agent they have heard of for two years is the one they ring. A new dwelling or a conversion to flats is a unit that has to be sold or let, and that instruction is decided long before the scaffolding comes down.
19,798 matching applications hit the UK register in the last 30 days — filtered down to just the councils or postcode areas you cover.
Why the register beats every other lead source
One instruction at an average UK fee covers the subscription for well over a year. The register hands you every improving household and every new unit in the areas you actually cover.
Exactly what we match for estate & letting agents
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.
| Trigger | Example from the register | Demand window | Confidence | Why it matters to you |
|---|---|---|---|---|
| Loft conversion / dormer | Loft conversion with rear dormer and 3 no. rooflights | 12 – 24 months | medium | a household spending this much is improving to stay or to sell — the agent who is visible during the build is the one they ring |
| Kitchen extension / open-plan kitchen | Single storey rear extension to form open plan kitchen diner | 12 – 24 months | medium | a household spending this much is improving to stay or to sell — the agent who is visible during the build is the one they ring |
| Two-storey / first-floor extension | Two storey side extension and single storey rear extension | 12 – 24 months | medium | a household spending this much is improving to stay or to sell — the agent who is visible during the build is the one they ring |
| Single-storey extension | Householder Planning Application - Single storey rear and side extension | 12 – 24 months | medium | a household spending this much is improving to stay or to sell — the agent who is visible during the build is the one they ring |
| Garage conversion | Garage conversion to habitable accommodation | 12 – 24 months | medium | a household spending this much is improving to stay or to sell — the agent who is visible during the build is the one they ring |
| Conservatory / orangery / porch / garden room | Erection of a conservatory to rear | 12 – 24 months | medium | a household spending this much is improving to stay or to sell — the agent who is visible during the build is the one they ring |
| New dwelling(s) / self-build | Planning Application for the erection of a two storey dwelling with garage | 6 – 18 months | high | a new or converted dwelling needs selling or letting, and the instruction is decided long before completion |
| Outbuilding / annexe / detached garage | Householder Planning Application - Detached garage. | 12 – 24 months | medium | a household spending this much is improving to stay or to sell — the agent who is visible during the build is the one they ring |
| Extension (storeys unspecified) | Proposed rear extension and internal alterations | 12 – 24 months | medium | a household spending this much is improving to stay or to sell — the agent who is visible during the build is the one they ring |
| Change of use to residential / HMO | Change of use from office (Class E) to 4 no. residential flats | 6 – 18 months | high | a new or converted dwelling needs selling or letting, and the instruction is decided long before completion |
| Renovation / alterations (catch-all) | Refurbishment and alterations to existing dwelling | 12 – 24 months | medium | a household spending this much is improving to stay or to sell — the agent who is visible during the build is the one they ring |
Householder improvements are a 12–24 month vendor pipeline, not this month's listings. New dwellings and residential conversions are nearer: 6–18 months from application to something that needs selling or letting. Demand windows are measured from the expected decision date. Refused and withdrawn applications are dropped automatically. How the demand windows are built →

Straight answers
Is this a list of people about to sell?
No, and anyone selling it that way is guessing. It is a list of households putting serious money into their property, which is the population future vendors come from, plus new and converted units that will need an agent. It is a pipeline to farm, not this month's listings.
Do large developments count?
Yes, and they are the strongest signal in the file. Big schemes are demoted for the building trades because a national contractor already has the work, but a forty-unit scheme is exactly the instruction an agent wants, so it is never demoted here.
Does exclusivity mean no other agent in my town?
It means no other agent subscriber on the areas you hold. The applications are public and anyone can read the register themselves — what you are buying is that we are not selling the same worked list to the agent down the road.
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 the moment something is filed 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.
