Heat pump leads: how heating contractors can set a workable budget

A heating contractor may welcome another heat pump installation and still lack the time for ten new consultations. The reverse is also possible: the sales team can respond immediately, but installation crews are already committed during the requested period. A workable enquiry budget therefore connects three things: the economic contribution from a project the business can actually deliver, the work required before a decision, and available capacity for both consultation and installation. Only within that context does the cost of an individual lead become meaningful.

The calculation below helps you prepare a limited purchase of new enquiries for your service area in Germany. Every figure belongs to an illustrative contractor. These are not webRichtung prices or predicted conversion rates. Replace the assumptions with your own project results and recorded working time. The intended outcome is a concrete decision: how much can you commit to a manageable group of contacts, and what would need to be true before you continue purchasing?

Start with the contribution from deliverable projects

Base the calculation on projects your business has the skills and organisation to undertake. A large order value alone does not tell you how much remains available for acquisition. Materials, your own installation labour and other costs directly attributable to delivery may consume a substantial share. In this working calculation, project contribution means the amount left after those costs but before the sales costs considered separately here. Write that definition on your worksheet so that you do not deduct the same labour twice.

Distinguish completed project accounts from preliminary estimates. If the scope of a potential job is still uncertain, its contribution is uncertain too. A higher sales ambition should not automatically justify a larger purchasing budget. Begin with a cautious comparison drawn from suitable work your own business has delivered, then revisit it once the actual scope is understood. This financial assumption does not establish technical suitability or decide which measures the building requires.

Your second starting point is the time genuinely available. Consider sales advice and installation separately. Two available installation slots in the planning period do not create unlimited site survey capacity. Prospective customers may also want different installation dates. Discuss their intended timing before mentally placing their project in an empty slot. Your schedule should reflect possibilities you have discussed, rather than assumptions about what a customer will accept.

With those starting values prepared, you can review the heat pump enquiry settings and register your business. The industry page explains the German service area, delivery options and monthly limit. It gives you a basis for aligning your enquiry order with your operation. Your business continues to provide the advice, professional assessment and proposal that turn an initial conversation into a considered project decision.

Make consultation work visible before purchasing

Record the full sales journey up to a clear decision. Include initial contact attempts, the conversation itself, examination of relevant documents, any useful site visit, preparation of the proposal and agreed follow-up questions. Not every enquiry needs every activity. That is precisely why it helps to count individual stages and record their actual duration, instead of assigning the same notional conversation time to every new contact.

Set an internal hourly rate for this assessment and explain what it includes. In the example, it is a costing assumption for sales work, not a price charged to the prospect. Add travel expenses or external services separately if they apply. If they are already covered by your time allocation or hourly rate, do not add them again. Getting this boundary right is more useful to a purchasing decision than expressing an unknown conversion rate to several decimal places.

Give each site visit a defined purpose. During the first conversation, you might ask whether the person plans to replace an existing heating system, what documents are available and what they need to understand next. These are suggested questions for your team, not claimed fields supplied with a lead. When documents are missing, obtaining them may be the most useful immediate step. When an on-site assessment is needed, you can prepare it around specific questions rather than arrange a visit without a clear task.

Geography belongs in the calculation as well. An area that is feasible for installation may still be expensive for frequent individual sales visits. Use your own travel records and experience. According to the service description, you can select Germany nationwide or a German postcode with a radius starting at 50 kilometres. That choice does not promise particular journey times or a convenient sequence of appointments. You must assess whether the available area fits the way your team provides advice.

Work through a complete starting calculation

Our illustrative contractor has two project slots available during the period under consideration and assesses a group of ten new enquiries. Ten is a calculation input, not a promised delivery quantity. The assumed contribution after directly attributable installation costs is €4,000 for each realised project. That figure is purely hypothetical. Sales opportunities that have not become projects are not entered as contribution already earned, even if the discussions seem promising.

For these ten enquiries, the team allows three hours in total for initial contact and conversation coordination. It adds six hours for consultations and document review, nine hours for three site visits including the travel time assumed in this example, and six hours for proposals and follow-up questions. This amounts to 24 hours. At an illustrative internal rate of €60 per hour, sales work costs €1,440. The simplified calculation assumes no other separately incurred costs.

The contractor hypothetically allocates €1,000 to purchasing the ten enquiries. This is neither a published offer nor a guide price. Enquiry purchasing and sales work together cost €2,440. If one deliverable project produces the assumed €4,000 contribution, €1,560 remains after the costs included here. If two such projects are realised, contribution reaches €8,000 and the remaining amount is €5,560. If the group produces no project, its result under these assumptions is negative €2,440.

The amount remaining is not automatically company profit. General overheads and other expenditure excluded from this exercise still need to be covered. For deciding whether to purchase this group of enquiries, however, it shows clearly how strongly the result depends on projects actually won and deliverable. Nothing in the arithmetic requires a claim that ten contacts normally produce one or two installations. Those are alternative outcomes for your own planning exercise, not forecasts.

Change the assumptions that matter most

A useful sensitivity calculation initially changes one assumption at a time. If the contribution from the single successful project falls from €4,000 to €3,000, the unchanged €2,440 costs leave €560. If processing time instead increases from 24 to 36 hours, sales work at €60 per hour costs €2,160. Adding €1,000 for the enquiries gives total costs of €3,160. A project contribution of €4,000 then leaves €840 after the costs considered.

If both changes happen together, a €3,000 contribution against €3,160 costs produces a negative result of €160. This is where the budget boundary becomes tangible. The purchase price per contact has not changed, yet the calculation has moved below zero. Longer consultation may be professionally necessary and should not simply be cut to rescue the spreadsheet. The business must reconsider its purchasing limit, contribution assumption or the amount of work it can sensibly take through the sales process.

Suppose the illustrative business wants at least €1,000 left from the enquiry group after the acquisition costs considered here. Assuming one project with a €4,000 contribution and €1,440 sales work, a maximum of €1,560 would be available for purchasing: €4,000 minus €1,440 minus €1,000. Spread across ten enquiries actually purchased, that gives a calculated ceiling of €156 each. This is a conditional internal limit, not a market price or a recommendation to spend that amount.

At a project contribution of only €3,000 and the same 24 working hours, that purchasing ceiling falls to €560 in total, or €56 per enquiry. With €3,000 contribution and 36 working hours, it becomes negative €160. Under those assumptions, sales work alone is already too expensive to leave the intended reserve; a positive enquiry purchase price cannot fit the chosen target. Keep these conditions beside the result so that an isolated number does not circulate in the next budget discussion without its explanation.

Keep enquiries, proposals and orders separate

Group enquiries by when they actually arrived and record their subsequent progress. Reaching a person, completing a consultation, visiting a site, sending a proposal and securing a project are different events. Combining them makes open proposals look like achieved results, even though the business has already incurred the work and has not established the return. Each case should therefore show its current stage, the next action agreed with the prospect and the time spent so far.

Review periods in a way that keeps outstanding decisions visible. If a proposal is accepted later, add the result to the original enquiry group. Crediting it to a newer group whose contacts did not generate that project would distort the comparison. Equally, an ongoing consultation should remain open rather than be declared lost prematurely. A small group is particularly useful for learning how your own workflow behaves; it does not prove a permanently reliable rate of success.

When projects do not materialise, examine what actually happened. Perhaps the requested installation dates did not match your availability, documents remained missing, or the person decided against the project. These are different findings for your next purchase. A brief factual case note is more useful than one sweeping judgment about every contact. Ask which changes your business can implement and which uncertainty will remain even when your team provides careful, professional attention.

Also monitor installation capacity. Once both available project slots in the example are firmly booked, a third customer wanting immediate installation does not automatically create extra benefit. You first need to establish whether another date is acceptable or additional reliable capacity exists. Do not count crews that have not actually become available. The next enquiry purchasing decision therefore belongs alongside the current installation schedule, as well as the analysis of previous sales activity.

Start with a bounded commitment and review it

Before starting, decide how much enquiry purchasing and processing your business can carry financially if no project is won initially. In the example, the costs included create an exposure of €2,440 with zero projects; your own number will differ. Reserve the corresponding consultation and site visit time as well. A budget line does not create a free hour in the calendar. Name the person responsible for continuing open cases and agree when the team will review their progress.

The monthly limit can cap regular deliveries within a calendar month; it guarantees neither that quantity nor an even delivery pattern. According to the current service description, standard enquiries are supplied to no more than three providers and exclusive enquiries to one provider. Exclusive delivery does not require the interested person to buy from you. Choose the delivery option using the current price shown and your own processing calculation, without inferring any particular number of completed projects.

Decide in advance what your first review should enable you to do. If time requirements and project contribution broadly match your assumptions, and suitable capacity remains available, further purchasing may be justified. If the workload is higher, investigate the cause first. If many cases remain open, follow their agreed next steps instead of covering the absence of completed decisions with more contacts. A deliberately limited start can then produce information that is useful to your particular business.

Replace the example inputs with your own project contribution, hourly costing and free capacity. You can then visit the heat pump page to review purchasing options and register your business. That page starts the existing access process, and the current price is shown before a binding order. With your calculation prepared, you can judge whether the actual offer fits your budget and what level of personal follow-through you will provide for the new conversations.
