INDUSTRY EVIDENCE
The evidence for enquiry leakage exists. It just comes from other industries.
CallingCrew is the first platform of its kind for wastewater installer networks. This page presents published research from adjacent sectors to demonstrate that each leakage mechanism is real, measurable and recoverable. The pilot establishes what that means for your network specifically.
All statistics on this page are sourced from named third-party research. None represent CallingCrew outcomes or wastewater-specific results.

UK wastewater suppliers went to voicemail out of hours
CallingCrew out-of-hours audit - September 2026
We called eleven UK wastewater supplier numbers after business hours. Ten went directly to voicemail. Two offered phone menu options. None used AI or automated enquiry capture of any kind.
Most potential customers will not leave a voicemail message. The enquiry disappears before the supplier knows it existed.
“Most potential customers will not leave a message when they can simply contact another supplier.”
This is CallingCrew's own primary research, specific to the UK wastewater sector.
Seven leakage points - the evidence
Each point is supported by published research from installation, trade, B2B services and manufacturer-dealer sectors. The mechanisms are identical to those found in wastewater installer networks.
Leakage point 1
Missed and unanswered calls
UK trades miss 1 in 5 calls on average. 85% of callers who reach voicemail do not leave a message. They call the next business on their list.

How CallingCrew addresses it
Out-of-hours and unanswered call handling
Leakage point 2
Slow lead response
Respond within one hour and you are 7x more likely to qualify the lead. The average business takes 47 hours. 63.5% never respond at all.

Leakage point 3
Abandoned web enquiries
81% of users have abandoned a web form mid-completion. Each additional field reduces conversion by 4.1%. 67% of those who abandon never follow up.

Conversational enquiry capture
Leakage point 4
Poor qualification and incomplete data
67% of lost sales are attributed to inadequate qualification, not product or price. In dealer networks: “The dealers will all do it differently.”

Consistent structured qualification
Leakage point 5
Unnecessary site visits
In solar installation, 30 to 40% of site visits have no realistic path to conversion. Remote pre-qualification reduced wasted visits by 40% with no impact on conversion.

Leakage point 6
Delayed or absent estimates
In an audit of 4,723 leads, 77% received no response at all. Honda UK achieved 30% more efficient network operations after implementing consolidated dealer performance visibility.

Leakage point 7
Enquiries passed without enough information
McKinsey found only 30% of executives have visibility beyond first-tier suppliers. Enquiries arriving directly at the installer are completely invisible to the supplier.

What recovery looks like in practice
Conservative assumptions. Your own numbers will differ. The pilot establishes the actual figures for your network.

Illustrative only. Uses conservative assumptions and does not represent a guaranteed or projected CallingCrew outcome. The pilot measures the actual recoverable value in your specific network.
Revenue already in the network, not being captured
£12,000,000
The pilot measures the real number.
We agree the baseline before we start - enquiry volume, response times, conversion rates - and measure the actual result against it. No assumed uplift. No projected outcomes. Just your network's real data.
- No obligation to proceed beyond the pilot
- No replacement of existing IT systems or processes
- Managed setup by CallingCrew, live in 2 to 3 weeks
- All data returned on exit within 30 days
- Available to supplier networks only, not sold direct to installers
