There’s a persistent assumption running through building products marketing: that the homeowner is the real decision-maker, and the installer is simply the last mile. Win the consumer’s attention, and the specification follows.
The data doesn’t support it.
The numbers below are UK proof points drawn from the Voice of the Installer Research Report: Loyalty, Incentives and Rewards (2026).
When installers are asked what drives their purchasing decisions, customer preference doesn’t make the top tier. Neither do peer recommendations or brand heritage. What ranks first (by a significant margin) is product reliability, cited by 72% of installers as their number one purchasing factor. Price comes second at 39%. Everything else is downstream of those two.
Installers are autonomous specifiers making pragmatic decisions based on lived experience with a product. They know what installs cleanly, what holds up after two winters, what generates callbacks and what doesn’t. That knowledge is hard-won, and it’s what they trust above all else.
This has significant implications for where manufacturers are spending their money.
The specification decision happens earlier than the brief
By the time a homeowner is describing what they want, the real decision is often already made. Installers build mental shortlists from experience: products they’ve used, trusted, and had no reason to move away from. A consumer campaign might create awareness, but it rarely overrides that shortlist. It certainly doesn’t rebuild it.
That means the more valuable intervention point is the installer’s existing preference set, and specifically, what it would take to shift it, or to lock it in.
When products are broadly comparable on reliability and price, 52% of installers say they’ll choose the brand that rewards them. The tiebreaker isn’t a TV ad or a glossy brochure left on the kitchen counter. It’s a well-designed incentive that makes the installer’s decision feel commercially rational.
What installers actually want from a reward programme
If the brief is to win installer logic, the programme design has to follow. And here, the data is usefully specific.
Tools and equipment are the most motivating reward for 61% of installers. Not experience days, luxury vouchers, or branded merch. Practical, business-relevant rewards that have direct utility on the job. The value it’s immediate and tangible. That distinction matters more than most programme designers acknowledge.
On structure, 33% prefer points-per-purchase and 23% prefer cashback — both straightforward, transactional models. Only 10% want Bronze/Silver/Gold tiering. Gamification has its place in consumer loyalty, but it doesn’t map well onto how tradespeople think about their time. Simple, predictable, fast.
The downstream numbers are compelling: 74% of installers are likely to stay loyal to a manufacturer offering meaningful rewards, and 56% say they’d put in real effort to earn rewards they truly value.
And for those wondering where to prioritise first: heating engineers are your most responsive segment, with 53% saying rewards have directly influenced the brands they recommend. In a category where a single installer might specify hundreds of units a year, that’s a significant concentration of influence.
The budget allocation question
None of this is an argument against consumer marketing. Brand visibility matters, and there are categories where homeowner pull-through is genuinely powerful. But in trade-led categories (HVAC, KBB, Smart Home, Energy) the specification logic runs through the installer, and the programme investment should reflect that.
The honest question for most manufacturers is whether their current budget split reflects where the decision actually gets made. Consumer campaigns are easier to sell internally. They’re visible, they’re measurable in familiar ways, and they’re brand-building. Trade incentive programmes are less glamorous and harder to attribute. But the research is clear about where the leverage sits.
An installer who trusts your product and is rewarded will recommend it, defend it, and default to it when the next job comes in. A homeowner who saw your ad will ask for it by name once, then defer to the person standing in their kitchen holding the pipe.
Treat them like the specifiers they are
The brands getting this right are treating installer loyalty as a commercial channel, not a marketing afterthought. They’re designing rewards around what matters to the installer’s business (tools, fast cashback, low admin) not around what looks good in a consumer loyalty playbook.
That distinction is what separates programmes that move share-of-wallet from programmes that generate sign-ups and then quietly accumulate lapsed users.
Installers are already telling you what they want. They want products that work, a fair price, and a reason to keep coming back that makes sense for their business. The brands that build programmes around that logic will create switching costs that competitors can’t easily buy their way past.
The homeowner doesn’t choose the brand. The installer does. It’s time the programme design caught up with that reality.
