A heat pump quotation form should not pretend to design a heating system. Its job is to identify suitable enquiries, explain the next step and give a qualified installer enough information to arrange an appropriate survey. For UK installers, the difference matters: a postcode and phone number may generate a lead, but they cannot establish a home’s room-by-room heat loss, emitter suitability or final installation cost.
This guide is for owners, marketing teams and survey coordinators at UK heat-pump installation businesses. It concentrates on the website-to-survey workflow rather than offering engineering design advice. For the wider channel strategy, read our HVAC marketing plan; for missed telephone enquiries, see our HVAC callback workflow. The examples and figures here are illustrative, not reported Vistoplex client outcomes.
The short answer: use a two-stage enquiry, not a pseudo-survey
Start with a short form that checks service area, project type, property type, existing heating, contact details and preferred next step. Follow with a human qualification call and, where appropriate, a professional site assessment. Ask for detailed drawings, radiator schedules and energy records later, when a trained surveyor can explain why they are needed. A preliminary online estimate must be labelled as indicative and subject to assessment.
Why heat-pump leads need different qualification from boiler repairs
A boiler breakdown enquiry is often urgent and constrained by immediate availability. A heat-pump installation is a considered purchase involving building fabric, hot-water demand, existing distribution systems, outdoor-unit siting, electrical provision and customer expectations. The same generic ‘Tell us your problem’ form treats two very different journeys as equivalent.
Installers also need to distinguish domestic retrofit, new-build, self-build, landlord enquiries and commercial projects. Those categories may involve different standards, funding eligibility, decision-makers and survey resources. Avoid promising grant eligibility from a handful of online answers; official scheme conditions can change and a competent installer must confirm the position.
Stage one: the seven questions worth asking first
1. Where is the property?
Request a full postcode if needed to establish genuine coverage, not a complete address at the first click unless the business has a clear operational reason. Use the result to route enquiries to the correct branch or decline out-of-area work politely. A postcode should not be used as a proxy for technical feasibility.
2. What type of project is this?
Offer choices such as existing-home replacement, new build, extension, commercial premises or unsure. A customer who is exploring options should be allowed to say ‘not sure’. Avoid forcing homeowners to choose between air-source and ground-source technology before anyone has explained the trade-offs.
3. What is the property type and approximate size?
A detached house, terrace, flat and multi-unit building can present different access and siting issues. Bedrooms or floor-area bands may be useful for initial routing, but they are not a reliable substitute for heat-loss calculations. Label approximate answers accordingly and never calculate a definitive unit size from bedroom count.
4. What heating system is in place?
Provide plain-language options: mains gas boiler, oil, LPG, direct electric, storage heaters, existing heat pump, district heating or other. Add an ‘unknown’ choice. This helps the team prepare for a conversation about replacement scope without turning the form into an eligibility decision engine.
5. What is the customer’s project timeframe?
Use flexible bands such as researching, within three months, three to six months and later. A realistic timeframe helps schedule survey capacity. Do not imply a particular installation date is available unless the scheduling system has actually reserved it.
6. What is the best contact route?
Collect a name, one usable contact channel and an optional preferred callback window. If the team genuinely needs a telephone conversation before booking a survey, explain that requirement rather than demanding both email and mobile without context. Make the confirmation message specific about when and how someone will respond.
7. Is there anything the installer should know?
Offer a short optional free-text field for access constraints, unusual property features or questions. Do not ask for medical details, occupancy patterns or other unnecessary sensitive information. The prompt can say ‘For example, listed property, limited outdoor space or existing underfloor heating’ while clarifying that the customer need not know technical specifications.
A practical field specification for developers
| Field | Required initially? | Validation / handling |
|---|---|---|
| Postcode | Usually yes | UK postcode format, manual correction and coverage check |
| Project category | Yes | Include ‘not sure’ |
| Property type | Useful | Simple choices; no assumptions about heat loss |
| Current heating | Useful | Allow unknown and other |
| Timeframe | Optional | No fabricated availability |
| Name and preferred contact | Yes | Clear purpose and accessible errors |
| Free-text context | Optional | Character limit, avoid sensitive prompts |
| Images or plans | Later | Secure upload only when needed |
| Marketing permission | Separate | Not bundled with enquiry response |
Use conditional questions only when they change the next action
Conditional logic can make the form shorter, but only if it reflects a genuine routing decision. For example, a commercial project may need a company name and site contact, while a homeowner does not. A self-build enquiry may need the expected build stage. An existing heat-pump replacement may need the make and symptoms for a service discussion. Do not add a question merely because the software can display it.
Keep every branch keyboard accessible and announce newly revealed fields to assistive technology. If a branch adds required questions, explain that change clearly. Test back-navigation, validation errors and mobile screens; conditional logic that hides an error can prevent a submission entirely.
Separate preliminary qualification from professional heat-loss assessment
An initial website form is a screening tool. A professional design assessment needs more detail, including room dimensions, building fabric, insulation assumptions, ventilation, heat emitters and hot-water requirements. The MCS heat-loss guidance explains why building heat demand must be assessed. The website should not present a rough online estimate as a compliant engineering design.
A useful customer-facing sequence is: enquiry received; human suitability review; survey offered with any fee explained; survey and design completed; written quotation issued; questions and grant position confirmed; customer decides. Explain whether an initial conversation is free, whether a survey is chargeable and whether any survey fee is credited against a later installation. These are commercial policies, not universal rules.
How to discuss the Boiler Upgrade Scheme without misleading visitors
The GOV.UK Boiler Upgrade Scheme guidance is the authoritative starting point for current scheme scope and conditions. Scheme availability, grant amounts, property criteria and installer obligations should be checked at the time of enquiry. A marketing form can ask whether the customer wants to discuss funding, but it should not show a guaranteed discount or final eligibility verdict without an appropriate assessment.
For Scotland, Northern Ireland and other circumstances, do not silently apply England-and-Wales scheme messaging. Where a business operates across jurisdictions, route the lead to the correct funding guidance. If displaying a sample price, distinguish gross installed cost, potential support and the estimated amount payable, with assumptions and an update date.
Explain the survey and quotation deliverables
A prospective customer should know what a meaningful quote will eventually address: the proposed equipment and output, relevant hot-water components, expected emitter or pipework changes, electrical work, controls, installation scope, commissioning, exclusions and aftercare. Where applicable, performance estimates and design documentation should be explained in accessible terms. This builds trust without pretending that every specification can be settled before the site visit.
A form confirmation can say: ‘We will review your enquiry and contact you about a suitability call. Any installation estimate is provisional until a survey and design review.’ This is more defensible than ‘Your heat pump will cost £X’ after three dropdowns. Give an actual response window supported by staffing, not an automatic ‘within one hour’ promise when nobody is on duty.
Build a CRM pipeline around decisions, not form submissions
Recommended stages are new enquiry, coverage checked, awaiting callback, qualified for survey, survey offered, survey booked, design in progress, quotation sent, follow-up due, accepted, declined and closed unsuitable. Assign one accountable owner and a next-action date to each active enquiry. Deduplicate calls and form submissions from the same household, and keep a record of why an opportunity was closed.
Route obvious out-of-area enquiries to a courteous message, not an unmonitored queue. For unsuitable technical enquiries, use a human review before making a final determination. A form can flag possible constraints but cannot responsibly conclude that a building cannot use a heat pump.
Example: a simple routing rule
If postcode is inside coverage and the project is an existing-home installation, assign the enquiry to domestic survey coordination. If it is a commercial property, send it to the commercial estimator. If the postcode is outside coverage, provide a clear explanation and a way to correct a mistyped postcode. Never route suspected safety emergencies through an ordinary quotation queue.
Privacy, consent and safe handling of attachments
The ICO’s data protection principles support collecting only information necessary for the stated purpose. State who receives the enquiry, how it will be used, the privacy notice and how to contact the business. If a marketplace shares leads with several installers, disclose that clearly before submission rather than hiding it in small print.
Responding to a requested quotation is not the same purpose as sending promotional newsletters. Provide a distinct marketing choice where needed and assess the appropriate UK GDPR and PECR rules; do not make marketing consent a condition of requesting a quote. Protect submitted data in transit and at rest, restrict CRM permissions and set a documented retention policy.
Do not demand EPC files, utility bills, floor plans or photographs in the first form unless they are genuinely necessary. Such files may expose addresses, possessions or personal details. When uploads are justified, limit accepted types and sizes, scan files, restrict access, avoid public media-library URLs and provide an alternative for users who cannot upload.
Accessibility and mobile usability checklist
Use explicit labels, visible focus indicators, adequate contrast and helpful error messages. Do not rely on placeholder text as the only label. Let users review their answers before submission and avoid unnecessary timeouts. The WCAG 2.2 recommendation provides the technical accessibility framework; automated tests alone cannot establish conformance.
Test the complete flow on a small phone with large text, on keyboard alone and with a screen reader. Verify postcode correction, conditional questions, consent choices, confirmation messages and server-side validation. If the form fails, publish an accessible telephone or email alternative and ensure it is actually monitored.
Measure qualified surveys and accepted work
Define a qualified lead before reviewing performance: for example, an enquiry inside coverage, requesting a service the company offers, with usable contact information and a plausible next step. Then distinguish raw submissions, contactable enquiries, booked surveys, completed surveys, issued quotations and accepted installations. Do not report all submissions as sales opportunities.
| Metric | Calculation | Interpretation |
|---|---|---|
| Contactable enquiry rate | Contactable enquiries / valid submissions | Detects spam and missing details |
| Survey booking rate | Surveys booked / qualified enquiries | Shows qualification and follow-up quality |
| Survey attendance rate | Completed surveys / booked surveys | Highlights confirmation and scheduling issues |
| Quote acceptance rate | Accepted quotes / quotes issued | Needs scope and margin context |
| Cost per accepted job | Attributed marketing spend / accepted jobs | More meaningful than cost per form |
Illustrative example: 100 valid enquiries yield 60 qualified leads, 30 booked surveys, 24 completed surveys, 18 quotes and six accepted jobs. The qualified-to-booked rate is 50%; the quote acceptance rate is 33.3%. These figures are arithmetic examples only, not market benchmarks. If a form change raises submissions but reduces survey completion, it may have made the process worse.
A 14-day implementation plan
Days 1–3: map enquiries and constraints
Interview the survey coordinator, installer and customer-service team. Review ten recent accepted projects and ten unsuitable enquiries, recording what information was actually needed to make the first decision. Audit the current form and document every field, error and follow-up promise. Confirm service coverage and the real number of surveys the team can deliver.
Days 4–6: build the minimum form
Create the short stage-one form, clear privacy messaging, a confirmation page and a fallback contact route. Connect fields to CRM stages, ownership and source attribution. Write plain-language questions and ensure the system handles ‘unknown’ responses. Avoid publishing unverified grant or fixed-price claims.
Days 7–9: test real journeys
Run homeowner, self-build, landlord, commercial, out-of-area and incomplete-form scenarios. Test with a mobile device, keyboard and screen reader. Confirm that every submission creates one case, sends the correct notification and appears in the right queue. Check that marketing permissions are stored separately from the enquiry.
Days 10–14: launch carefully and review
Launch to a controlled share of traffic if practical. Review submission errors, callback completion, survey bookings and qualitative feedback daily. Keep the previous form available for rollback. After two weeks, inspect outcomes rather than declaring success from an increase in button clicks. Document what changed and when so later SEO or conversion analysis is interpretable.
Common mistakes that cost installers time
- Calling a rough estimate a fixed quote before a professional survey.
- Asking for detailed technical specifications that ordinary homeowners cannot know.
- Showing one funding scheme to every UK visitor regardless of location or eligibility.
- Treating a requested callback as consent for unrelated marketing.
- Routing commercial and domestic projects into one unowned inbox.
- Demanding plans and bills before explaining their purpose and security.
- Optimising for cheap leads while ignoring booked surveys and accepted jobs.
- Claiming same-day survey availability without a live capacity check.
Frequently asked questions
Should a heat-pump quote form ask for the EPC rating?
It can be an optional contextual question, but do not make a remembered EPC rating a barrier to initial contact. An EPC is not a substitute for professional heat-loss design, and customers may not know whether the certificate is current.
Can the website calculate heat-pump size from floor area?
It can offer an explicitly rough educational illustration if responsibly framed, but it must not label that result as a design recommendation. A qualified professional needs a more detailed assessment before selecting equipment.
Should homeowners upload photos?
Only when the images help the next decision and the customer understands why. Optional photos of an existing boiler or potential outdoor location may be useful later, but they should not replace a survey or become a compulsory first-step hurdle.
What should happen after submission?
Show a clear acknowledgement, realistic contact window and the next step. The CRM should assign an owner and preserve the enquiry details so the customer is not forced to repeat everything. If the business cannot serve the location, say so promptly.
How do we avoid misleading grant claims?
Link to current official guidance, specify the jurisdiction, describe support as subject to eligibility and installer assessment, and review any displayed amounts regularly. Do not promise a grant merely because a user selected ‘gas boiler’.
The takeaway
The best heat-pump enquiry form does less at the beginning and more after a qualified person becomes involved. It collects the minimum information needed to route a real customer, sets expectations for survey and design, respects privacy and accessibility, and measures accepted work rather than vanity lead counts. That creates a more useful experience for both homeowners and installers.
