Heat pump & heating engineers — planning application leads | PlanWatch
PlanWatch Demand Radar · for heat pump & heating engineers

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

Grant-driven demand spikes are unplannable; register flow is steady.
Extension projects rarely google "heating engineer" — the builder just calls someone. Beat that call.
Every conversion to flats/HMO re-plumbs heating per unit.

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.

See what’s in your patch

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.

How it works

1. Pick your patch

The councils or postcode prefixes you cover — a town, a county, or several.

2. We scan the register

Every month we cross live planning applications from 378 UK councils with the trigger model above and score the demand window.

3. You get a mailing list

A deduped, mailing-house-ready CSV of "Owner/Occupier" addresses — one household, one letter, prior recipients suppressed automatically.
