Heat pump applications, plus the extensions and conversions that force a heating rethink.
ASHP applications are declared intent. Extensions and conversions quietly out-demand them: more rooms means the boiler conversation happens whether the homeowner planned it or not.
2,401 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
ASHP installs run £8,000–£18,000 (BUS grant softens the ask). Extensions add steady system-upgrade work.
Exactly what we match for heat pump & heating engineers
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 |
|---|---|---|---|---|
| Heat pump installation | Installation of an air source heat pump to the side elevation | now – 2 months | medium | declared heat-pump intent — but a share of applications are filed by an already-appointed installer, hence medium |
| New dwelling(s) / self-build | Planning Application for the erection of a two storey dwelling with garage | 4 – 9 months | medium | heating system is specified mid-build |
| Extension (storeys unspecified) | Proposed rear extension and internal alterations | 2 – 6 months | low | extensions commonly extend or upgrade the heating system — unconfirmed |
| Change of use to residential / HMO | Change of use from office (Class E) to 4 no. residential flats | 3 – 9 months | low | conversions re-plumb heating per unit — unconfirmed |
| Renovation / alterations (catch-all) | Refurbishment and alterations to existing dwelling | 1 – 6 months | low | refurbishments frequently replace the heating system — unconfirmed |
Heat-pump applications 0–2 months; extension-driven heating work 2–6 months after consent. Demand windows are measured from the expected decision date. Refused and withdrawn applications are dropped automatically. How the demand windows are built →

Type the councils or postcode areas you actually work. 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.
