The Leak Detective

The Leak Detective grew out of a Scottish leak detection business that had already traded for several years before franchising. Its strongest foundations are a clear customer problem and a clear operator profile. It finds leaks that can be difficult to locate through routine plumbing work, and it recruits people who can investigate a fault, explain the outcome and produce a usable report.

• A1, proven and profitable core model, 2.5/5. The original business traded for years and the service has been replicated in UK territories. The franchisor and its consultant describe a profitable model. Public evidence does not establish the core business’s operating margins or give enough detail to independently verify profitability.
• A2, 30 days without daily founder involvement, 2.5/5. David Hunt described the Scottish operation as a managed business. Regional operators and a franchise management function provide further evidence of delegation. The extent to which the franchisor can run for 30 days without daily founder involvement remains unverified.
• A3, ideal franchisee, 3/3. The offer sets out the technical aptitude, problem-solving, communication and reporting skills it looks for. It identifies two practical routes into the network: a specialist owner-operator and an existing trade business adding a service.
• A4, franchisee commercial viability, 2/4. Named operators are trading, the service can generate paid investigative and repair work, and some operators have added it to an existing business. Public material provides indicative start-up costs and promotional earnings claims, with insufficient evidence of typical job volume, expenses and franchisee net profit.
• A5, market positioning, 3/3. Non-invasive investigation, equipment and training, insurance-facing reporting and the option to add leak detection to an established trade business give the opportunity a distinct position.

The biggest unanswered commercial question is what a typical franchisee keeps after engineer time, van and equipment costs, ongoing fees, marketing and the ramp-up period. Representative results from both standalone and add-on operators would make that comparison possible.

Build is one of the best-evidenced parts of the network. Ashtons Franchise Consulting describes creating the franchise manual and supporting the rollout. Claromentis documents how The Leak Detective responded when a growing network made scattered folders, email and manual onboarding tracking harder to manage.

• B1, documented operational playbook, 5/5. The franchise manual is explicitly documented. The live knowledge base holds standard operating procedures, service guidance and answers to recurring questions.
• B2, structured onboarding and training, 4/4. Technical training, equipment support and onboarding steps are evidenced by the recruitment offer, the franchise consultant and the platform case study.
• B3, documented brand experience, 2/4. Common technical guidance, report templates and branded regional pages support consistent delivery. The full customer experience standards and how adherence is measured across territories could not be verified publicly.
• B4, central access to tools, templates and systems, 3/3. The Claromentis Franchise Hub brings together operational documents, policies, peer discussion and support tickets. The separate CRM supports job reporting.
• B5, launch without constant founder input, 2/4. Searchable procedures, routed support requests and a Franchise Manager give a new operator practical ways to get answers. Public evidence does not yet show how independently a full launch now runs.

The support hub addresses a specific scaling problem. Operators can find routine answers themselves and route technical questions to the right person. Time to first job and the number of support interventions per new operator would show how much difference the change has made.

Launch is the strongest fibre. A prospective franchisee can see what the work involves, why the service exists, who the opportunity is for and how to request a prospectus. The positioning makes particular sense for a plumbing, heating or property repair business that already has vehicles, engineers and customers.

• L1, clear franchise proposition, 5/5. The offer sets out the specialist service, the skills and systems provided and the two ways to enter the model.
• L2, messaging for the right potential franchisee, 4/4. The directory copy and territory campaigns speak directly to technical operators and relevant trades. Glasgow North provides a named example of an existing plumbing and heating business taking on the franchise as an add-on.
• L3, clear enquiry journey, 4/4. The official recruitment page directs prospects to an enquiry form and explains that a prospectus follows by email. Phone and directory enquiry routes are also visible.
• L4, structured discovery before acceptance, 2/4. Ashtons confirms that a recruitment process was developed. The public material gives limited detail on candidate screening, technical assessment, discovery meetings and how final territory awards are made.
• L5, plan for taking the franchise to market, 3/3. The documented development work included a prospectus, marketing plan and recruitment process. The 2023 launch, trade-targeted advertising and subsequent directory activity show that the plan reached the market.

The main gap is between receiving the prospectus and signing. A clearer public explanation of how both sides test fit, what the agreement covers and how candidates can speak to existing franchisees would make that stage easier to understand.

The Leak Detective has shown it can recruit franchisees and open territories. The early Milton Keynes announcement was followed by openings and awards across several regions. Ashtons reported that rapid growth in 2025 led the network to pause recruitment for four months so it could concentrate on onboarding.

• G1, consistent monthly franchise enquiries, 2.5/5. A live opportunity site, directory enquiries, Facebook advertising and targeted territory campaigns show lead-generation activity. Current monthly volumes and consistency were not publicly evidenced.
• G2, tracking enquiry sources and prospect quality, 2/4. David Hunt identified Facebook as the source of the first two franchisees and described how high enquiry volume translated into relatively few suitable prospects. That is evidence of some attribution and quality assessment. A current, repeatable channel reporting process could not be verified.
• G3, known enquiry-to-franchisee conversion rate, 0/4. No current conversion rate or comparable funnel figures were found. An early account of Facebook enquiries and signings does not give a reliable conversion rate for the whole network.
• G4, clear territory expansion priorities, 3/3. The advertised priorities include Northern Ireland, Newcastle, Liverpool, South London, Wales and Norwich. Northern Ireland was separately promoted by the Franchise Manager. Some of these are broad areas, so availability at postcode level should be checked directly.
• G5, recruitment beyond the founder, 2/4. Emma Gallacher publicly promotes opportunities, and candidates can enter through the site or franchise directories. The evidence shows recruitment activity beyond the founder, with limited visibility into who qualifies candidates, leads discovery and closes agreements.

The four-month pause makes onboarding capacity part of the recruitment story. The next measure of repeatability is how consistently suitable prospects become trained, trading operators, with enough support at each stage.

The Leak Detective gives operators several ways to become visible to customers. The national website has postcode and area coverage pages, the package advertises lead generation and customer service support, and the brand reports work coming through direct customers, property managers, loss adjusters, housing associations and insurance networks.

• AM1, local customer enquiry support, 5/5. The franchise offer explicitly includes ongoing marketing and lead generation, customer service support and access to insurance claims networks. Local service pages provide a visible route for customers to enquire.
• AM2, local online presence for every franchisee, 2/4. Regional and town pages are extensive, with examples in Humberside, Bristol, South Wales and Scotland. Some pages serve the same operator. Without a current operator roster, it is not possible to match a local presence to every franchisee.
• AM3, clear local marketing plan after launch, 2/4. Central marketing support, location pages and case-led content give operators a starting point. The ongoing local marketing plan each franchisee is expected to follow could not be verified.
• AM4, customer enquiry and performance tracking by franchisee, 0/3. The network advertises CRM and report-writing tools. Public sources do not show that lead source, bookings, conversion and commercial performance are tracked consistently at operator level.
• AM5, customer acquisition beyond referrals, personal networks or the founder, 2/4. Regional pages, central enquiries and direct customer routes exist. The network does not publish the mix of enquiries or jobs per territory, so the extent of operator reliance on referrals or pre-existing relationships remains unclear.

The distinction is between giving an operator a route to enquiries and knowing how reliably that route produces profitable jobs. The public evidence establishes the former. The latter would require a territory-level breakdown of enquiries, jobs and revenue by source.
