Why More Leads Won’t Automatically Mean More Solar and Heat Pump Sales

For solar and heat pump installers, generating more enquiries can seem like the obvious way to grow. More leads should mean more surveys, more quotes and, ultimately, more installations. But that only happens when the business has a sales process capable of turning those enquiries into customers.

During an InstallrHub webinar, Brad Clark explained why installers need to look beyond lead volume and examine what happens at every stage of the customer journey. His central point was straightforward: additional demand will not automatically benefit every installation business equally. The businesses that respond effectively, build trust and convert opportunities are better positioned to make the most of it.

More leads can hide a bigger problem

Imagine two installation businesses.

The first receives 20 leads, converts five into quotes and wins one installation. The second receives 35 leads, converts 40% into quotes and closes 30% of those quotes.

Using the example figures discussed in the webinar, the second business has a much stronger conversion process. The difference is not simply that it receives more leads. It also gets more value from the opportunities entering its sales funnel.

This distinction matters because lead generation costs money. If an installer spends money on advertising but loses opportunities through poor qualification, slow follow-up or weak sales conversations, increasing the advertising budget may increase the cost of the problem rather than solve it.

The same principle applies to businesses at different stages of growth. A new installer working with a limited budget may waste a significant proportion of their available marketing spend if too few enquiries progress to surveys and installations. A larger business spending substantial amounts on advertising may lose considerable revenue through relatively small inefficiencies in its conversion rates.

Understand where opportunities are being lost

The first step is to stop treating lead generation as a single activity. An enquiry has to progress through several stages before it becomes a completed installation.

A homeowner needs to be contacted, qualified and booked for a survey. The installer then needs to assess the property, prepare an appropriate proposal, follow up and help the customer make a decision.

Every stage creates an opportunity for the process to break down. Enquiries may not receive a timely response. Appointments may be booked with homeowners who are not a good fit. Quotes may take too long to arrive, or the business may fail to follow up consistently.

Without tracking the journey, it is difficult to identify which stage is responsible for disappointing results.

Installers should begin by measuring how many enquiries become appointments, how many appointments result in quotes, and how many quotes turn into installations. They should also examine the reasons opportunities do not progress. This creates a clearer picture of whether the immediate problem is lead quality, appointment booking, sales conversion or something else.

Why finance alone will not win the customer

The webinar also explored how the proposed Warm Homes Loan Scheme could affect buying decisions. Lower-interest or zero-interest finance options could reduce a financial barrier for some homeowners and make renewable technology more accessible.

However, the customer would still need to borrow and repay the money. That means homeowners would continue to make decisions about which installer they trust, which proposal they understand and which company gives them confidence in proceeding.

Finance can influence the decision, but it cannot replace the sales process around it.

Brad drew a comparison with the ECO4 market, where InstallrHub had managed more than £1 million in advertising spend and generated thousands of jobs for installers. Some businesses grew quickly during that period, while others failed to take full advantage of the opportunity. The lesson was not that every future scheme would reproduce ECO4, but that changes in market conditions do not distribute opportunities evenly.

Installers still need the foundations to convert demand into profitable work.

Improve the process before increasing the budget

A useful review starts with the numbers already available. How quickly does the team respond to an enquiry? What proportion of leads becomes a survey? How long does it take to send a quote? How consistently are quotes followed up? Which reasons most often prevent a sale?

These questions help the business prioritise improvements instead of automatically spending more to generate additional leads.

It is also important to consider whether the business can fulfil the work it wins. Lead generation that exceeds survey or installation capacity may create delays and a poor customer experience. Growth needs to be supported by the people, processes and operational capacity required to deliver the work.

The aim is not simply to increase the number of enquiries. It is to improve the number of suitable opportunities that become profitable installations.

Start with the gaps in your sales process

Before committing to a larger marketing budget, installers should understand how their existing process performs. Better visibility can help more homeowners discover the business, but the business still needs to respond promptly, communicate clearly and convert those opportunities into work.
