Extreme Growth · Renewables
We examined 700 live ads and 39 landing pages across UK heat pump and solar businesses. What we found exposes where paid homeowner interest can disappear before it becomes a signed installation contract.
Extreme Growth builds and operates the acquisition process that connects those steps. Our work is measured against the cost of winning signed installation contracts.

Extreme Growth Research · October 2026
We investigated 23 heat pump advertisers and 20 solar and battery advertisers. We examined their advertising and tested the pages homeowners reached after clicking. Here's what we found.
Already use a qualifying quiz
Some of the most active advertisers in the sector are already asking homeowners questions before passing the enquiry to their team.
Advertisements carried a Book Now button
The overwhelming majority still directed homeowners towards quotations, information or form submissions.
Booked the homeowner's survey directly on the page
Even the businesses using qualification funnels left the appointment to be arranged afterwards.
Landing pages scored below 50 on mobile performance
The median largest-contentful-paint was 5.9 seconds.
Source: Extreme Growth research, 10 October 2026. Findings describe the advertisers, advertisements and landing pages examined.
A homeowner sees your advertisement. They're interested enough to click. They complete a form or qualifying survey. Then they wait.
Somebody in your office has to pick up the enquiry. Reach the homeowner. Confirm the project details. Arrange a suitable survey time. And move the opportunity into your sales process.
Meanwhile, that homeowner may be speaking with other installers.
The advertising has already cost you money before the appointment is even confirmed.
The opportunity in your enquiry queue
Picture a homeowner who has spent the evening researching heat pump grants. They've looked at installation costs. They want to understand whether their property is suitable. They submit an enquiry at 9.15pm.
Or consider a homeowner researching solar panels and battery storage. They've compared system sizes, equipment brands and estimated savings. They finally decide to request a quotation.
Both are interested enough to take action. But your office has closed. Your sales team is busy. The enquiry waits until the next working day.
By then, the homeowner may have continued researching, contacted another company or lost interest in arranging the survey. Research into online sales leads has repeatedly found that response time affects the likelihood of reaching and qualifying an enquiry. For an established renewables installer, that matters because each suitable project represents a meaningful commercial opportunity.
The objective is to make the next step available while the homeowner is still interested.
Qualify the project
Establish the homeowner's circumstances, requirements and readiness to proceed.
Respond immediately
Keep suitable homeowners engaged while their interest is highest.
Book the survey
Move the homeowner towards the appropriate next step — and give your team the context they need.
Heat Pumps
They may be replacing an oil or gas boiler. They may be investigating grant eligibility. They may be concerned about running costs, radiator upgrades, installation disruption or whether their property is suitable.
A generic quotation form doesn't answer those concerns. And a homeowner who is simply curious about grant funding isn't necessarily ready for a technical survey.
Your acquisition process should help establish the homeowner's circumstances, project requirements and readiness to proceed — so your team can focus on suitable installation opportunities.
Solar & Battery Storage
They may be comparing system sizes. Looking at battery storage. Considering how much electricity they use. Comparing equipment and installation quotations. Or deciding whether the expected savings justify the cost.
The right message needs to speak to those questions. The qualification process needs to identify the project. And the appointment needs to move the homeowner towards an informed buying decision.
Different projects. Different buying concerns. One commercial objective — lower the cost of winning suitable installation contracts.
Grants, VAT & the homeowner's buying decision
Government incentives are a significant part of the conversation around renewable heating and energy installations. But a homeowner responding to a grant advertisement may still have a long list of unanswered questions.
Heat Pump Grants · Boiler Upgrade Scheme
For eligible air-to-water and ground-source heat pump installations.
For eligible off-gas homes under the temporary enhanced support running from 21 July 2026 to 31 March 2027.
For eligible air-to-air heat pump installations following their inclusion from 28 April 2026.
The scheme is funded through 2029/30, and the EPC requirement has been removed.
Source: Department for Energy Security and Net Zero. Eligibility, scheme conditions and available support should be checked against current official guidance.
Solar, Battery & Installation VAT
Qualifying heat pump, solar and battery installations currently benefit from 0% VAT under the applicable rules through 31 March 2027.
Source: UK government energy-saving materials VAT rules. Eligibility and dates are subject to current legislation.
Your advertising may start the conversation with the incentive. Your acquisition process has to carry the homeowner through the decision.
That means asking the right questions, providing relevant information, qualifying the project and making it easy to book the appropriate next step.
Cost per contract won.
£13,100
Average heat pump installation cost.
£7,500
Typical 4 kW solar installation, before battery storage.

Those are substantial homeowner investments. But the value of the installation doesn't tell you how efficiently your business acquires the work. For that, you need to understand what happens from advertising spend through to signed contract.
How many suitable homeowners enquire? How many book? How many appointments take place? How many quotations are issued? How many contracts are signed? And what did it cost to produce those contracts?
That's the commercial picture we help you improve.
Because an enquiry that never becomes an appointment still costs money. A survey with an unsuitable homeowner consumes time. And a quotation that fails to communicate the value of your installation may never become a contract.
The Referral Effect
We call this The Referral Effect. It shapes your advertising, landing pages, qualification journey and follow-up — establishing relevance and trust before the sales conversation begins.
Think about a homeowner referred by a previous customer. They may already have seen the installation. They've heard somebody describe the experience. They have a reason to trust the company before making contact.
Now think about the homeowner who discovers you through advertising. They don't have that introduction. They may be comparing several installers. They're trying to decide who understands their property, their concerns and the investment they're considering.
The language they encounter matters. That's why our work begins with the projects you most want to win and the homeowners most likely to buy them. We investigate what those buyers care about, what they worry about, what makes them hesitate, what evidence they need, and how your business can communicate its expertise in a way they understand.
So the homeowner arrives with a clearer understanding of why your business deserves consideration.
The Extreme Growth Acquisition System
We build the system around your installation business: your service area, your target projects, your survey capacity, your sales process and the type of homeowner you want to attract.
Our research found that 29 of 63 renewables advertisers were running five creatives or fewer. Among heat pump advertisers, 15 of 23 were running five or fewer. Different homeowners respond to different concerns, evidence and messages. We develop and test a range of creative variations suited to the available advertising budget — potentially 10 to 100 variations across messages, images, video and formats — refreshing creative as the results develop.
Across the 39 renewables landing pages we tested, none achieved a mobile performance score of 90 or above. The median largest-contentful-paint was 5.9 seconds. Google's published good-performance threshold for that measure is 2.5 seconds. We build dedicated mobile-first landing pages designed to respond quickly and move the homeowner towards the next step.
For heat pumps, the questions can explore property circumstances and installation suitability. For solar and battery, they can establish project requirements and relevant household information. The qualification process is built around the service being offered — so your team receives useful context before the appointment.
Suitable homeowners can book the appropriate survey or consultation directly from the qualification journey. No separate callback required simply to arrange the next step.
Automated messaging and conversation systems help respond when your office is closed or your team is occupied — keeping suitable homeowners engaged and moving towards the appointment.
The system records what happens after the initial enquiry: appointments, qualified opportunities, sales outcomes and contracts won. That information is used to inform future acquisition decisions.
We work with your team on the journey from survey to quotation and signed contract. The homeowner's concerns, the evidence presented and the way value is communicated all matter — because improving acquisition efficiency requires attention to the entire process.
From the first advertisement to the signed contract.
Our research found that 17 of the 63 renewables advertisers already used qualifying quizzes. Some were among the most active advertisers in the sample. That means qualification is already part of the acquisition process for a meaningful proportion of the market.
But the quiz itself is only one step. What happens when the homeowner finishes it?
Those are the questions we'd investigate.
See which parts of your acquisition process deserve attention first.
Delivery
Once we understand your business and agree the strategy, we begin building the acquisition system: the message, the advertising, the landing pages, the qualification journey, the appointment booking, the response process and the reporting.
Our commitment is to build and launch the agreed system within 30 days of commencement. Then we begin measuring and improving the commercial results.
The Guarantee
Before we begin, we establish your existing cost per contract won — using agreed advertising expenditure, acquisition management costs and signed contracts attributable to that activity. That becomes the starting baseline.
Our commitment is to bring your cost per contract won below that baseline within 90 days.
If we don't, we continue working without our management fee until we do.
The guarantee operates under agreed conditions, including accurate sales reporting, timely enquiry handling and the cooperation required to measure performance.
Relevant Client Experience
Mike
Design & Build90 days
pipeline filled
Mike's $3.4M design and build business had project delays that created gaps in its forward pipeline. Within 90 days of implementing the acquisition system, those gaps had been filled. The business was booking projects into November 2027.
Richard
Smart Home Installation$340,000
project closed · 5 additional qualified showroom demos / month
Richard's business already had valuable referral relationships. The acquisition system created an additional source of qualified opportunities alongside them.
Tomas
Smart Home Installation£75,000
average order value
Tomas wanted one additional sale every six weeks because of the impact it could have on annual revenue. His acquisition activity has been generating four to six booked conversations, associated with one to two sales.
These examples are from related design, build and installation businesses rather than heat pump or solar-specific campaigns. Individual results depend on the market, project value, sales process and operating conditions.
Exclusivity
We work with one installation partner per agreed service category and protected area. If we partner with a heat pump installer covering Berkshire, we won't take on a competing heat pump installation business in that protected territory.
Solar and battery installation is assessed as its own service category. We establish the territory and any overlapping services before entering an agreement — because the acquisition system is built around your market, your customers and your commercial objectives.
Extreme Growth primarily works with established UK installation companies already investing in customer acquisition — businesses with installation capacity, a proven service, operational systems, meaningful contract values and the ability to fulfil more work.
We also support businesses offering related renewable heating and energy storage services where the acquisition economics make sense. For smaller teams that prefer to operate the system themselves, we provide a guided implementation route with access to tools, training and support.
The Installation Profit Audit helps us understand which approach may be suitable. You don't need to choose a package before taking it.

P.S. If your business already uses a qualifying quiz, that's a useful starting point. The important question is what happens afterwards — including the appointment, the response, the quotation and the signed contract.
P.P.S. We work with one installer per agreed service category and territory. If your business is a suitable fit, territory availability will be checked before any partnership is offered.
