Air-to-air enquiries should increase now that the public grant number is visible. That is useful, but it also creates a risk: customers may ask for a cheap system before the installer knows whether the property, room layout and routes make sense.
The right move is not to over-explain the scheme on the doorstep. It is to collect the facts quickly, then let the office price from evidence.
1. Confirm the grant route first
| Question | What to confirm | Why it matters |
|---|---|---|
| Is it actually air-to-air? | The proposed system heats the home by supplying warm air through indoor units, not through a wet radiator or underfloor circuit. | The customer may use "air source" loosely. The grant route depends on the system being described accurately. |
| Is it eligible work? | Check the job against the current Boiler Upgrade Scheme rules before making any promise on the discount. | The grant is not a general cash-back offer. It sits inside the scheme rules and application process. |
| Is it a hybrid? | Find out whether the customer expects to keep another main heating system in a way that affects eligibility. | GOV.UK says hybrid heat pump systems are not eligible for a grant. |
| Who applies? | The installer applies and the grant is shown as an upfront discount on eligible work. | This avoids the customer expecting a separate payment to arrive later. |
2. Keep the quote wording clean
Use plain language. The customer should see the job price, the grant line and the net price clearly. Do not bury the grant inside a vague discount.
A safe wording pattern is: "Includes the Boiler Upgrade Scheme grant deduction where the final installation is eligible and the application is accepted." That keeps the commercial promise tied to the scheme outcome.
3. Capture the evidence that changes the price
- Room list, room use and which rooms the customer expects to heat.
- Photos and notes for possible indoor unit positions.
- Outdoor unit location, access, clearance and nearby boundaries.
- Refrigerant route, wall penetrations and realistic pipe route.
- Condensate route, especially where gravity drainage is not obvious.
- Consumer unit location, spare capacity context and isolator position.
- Existing heating system, retained heat source and any customer expectation to keep it.
- Photos that show awkward access, making-good risk, scaffolding needs or restricted routes.

4. Watch for these red flags
| Red flag | What it usually means |
|---|---|
| "We only need one unit downstairs" | The customer may be comparing a comfort-cooling quote with a whole-home heating route. |
| No clear outdoor-unit position | Noise, boundary, access or pipe-route issues may move the quote. |
| Existing heating is staying | The job may need closer eligibility checking before anyone talks about the grant. |
| Long or hidden refrigerant routes | Labour, materials, access and making-good can move quickly. |
5. Hand the office a job they can price
The best survey does not try to design the whole system on site. It gives the office enough evidence to decide whether the job is straightforward, whether more design work is needed, or whether the grant conversation is premature.
That is where the survey earns its keep: it stops a policy-led enquiry turning into a rushed quote with gaps all over it.
