Home Improvement and Renovations · Renovation · Property Renovations

Prokil is a property care franchise specialising in damp, timber and waterproofing services. Its published history begins in Bournemouth in 1965, when Jim Thorne established the first branch. Carlo Marsango took over following the founder's retirement in 2010, and the later involvement of his son Alex supported development of the franchise operation.

The Five Fibre score measures this network against Twine Growth's Five Fibre Framework™ using the information available at the assessment date. It is not an endorsement, a financial recommendation or a recommendation to purchase a franchise.

About the network

More about Prokil.

Services are supplied to residential and commercial customers and include damp surveys, mould treatment, timber preservation, woodworm and rot treatment, structural waterproofing and repair work. Basement tanking and conversions also appear in the published service range. The business therefore combines assessment of property problems with the delivery of remedial work, rather than selling one standard treatment for every building.

The franchise offer includes an exclusive territory, subject to the agreement, and technical and business preparation for new partners. The published programme describes three months of training combining head office work, practical experience and time alongside surveyors. Later stages introduce work in the local area with head office assistance.

Training covers property care, business management and developing the local operation. Recruitment material also describes examination fees for a remedial surveying qualification, with the qualification dependent on completing the relevant preparation and passing the examination. Inclusion of that support is different from automatic professional certification when purchasing a franchise.

Continuing guidance addresses operational challenges, improvements and developments in the industry. Partners build relationships with local property customers while using the brand's methods, resources and technical knowledge. Published branch totals and ambitions have not been treated as a verified count of independent franchise owners, and advertised turnover potential is not a guaranteed financial result.

Five Fibre assessment

How the foundations score.

Every franchise network is assessed across the five connected areas Twine Growth believes support sustainable franchise growth.

How the Five Fibre score is calculated

01 Assess Strong13/20

Assess: Current property-care delivery, a specific operator profile and supported territorial model establish a developed proposition. Actual core profitability, representative owner net earnings and thirty-day principal independence remain incompletely verified.

  • Profitable core business: Partially, 2.5/5. Longstanding property-care work, named local operations and selected owner cases substantiate trading. Actual current core-business profit was not established from turnover claims or business longevity.
  • Operates for 30 days without daily founder input: Partially, 2.5/5. The original founder’s retirement, successor leadership and locally managed teams support transferability. A verified thirty-day period without daily involvement from current central principals was not established.
  • Ideal franchise owner defined: Yes, 3/3. The offer addresses new business owners, experienced operators and existing property-care businesses considering conversion, with a clear emphasis on customer care, learning and workmanship.
  • Realistic owner money: Partially, 2/4. A selected Brighton owner reports increased earnings alongside higher turnover. Representative actual owner net profit after staffing, delivery costs and central charges was not verified.
  • Different opportunity: Yes, 3/3. The proposition combines specialist property-care services, technical preparation, exclusive areas, central marketing and business support rather than merely licensing a trading name.
02 Build Strong16/20

Build: Structured practical preparation, documented brand guidance, CRM updates and specialist support evidence repeatability. A complete owner operating playbook and one location containing every resource were not fully established.

  • Documented operating playbook: Partially, 2.5/5. The business refers to a proven blueprint, training resources and CRM-delivered guidance. A complete current documented franchise operating playbook covering the whole business was not explicitly verified.
  • Structured onboarding: Yes, 4/4. Published preparation lasts around three months and combines head-office work, shadowing surveyors, local practice and technical qualification support, followed by continuing assistance.
  • Documented brand experience: Yes, 4/4. The marketing page expressly identifies brand guidelines and supplied approved assets, alongside uniforms, stationery and signage supporting a consistent experience.
  • One central resource location: Partially, 1.5/3. A central CRM distributes updates and resources, and an owner case describes streamlined bookings and leads. Complete consolidation of all operating tools, templates and systems was not verified.
  • Launch without constant founder involvement: Yes, 4/4. Expert surveyors, head-office staff, tailored onboarding and supported local work provide a repeatable launch route beyond constant answers from one founder.
03 Launch Scale Ready18.5/20

Launch: The opportunity has a clear proposition, targeted entrant routes and a detailed consultation-to-agreement journey. A complete current ownership acquisition campaign plan is less publicly visible.

  • Clear franchise proposition: Yes, 5/5. The opportunity explains property-care services, territory, support, investment components and ongoing management charges. High turnover claims are not treated as personal income guarantees.
  • Targeted applicant attraction: Yes, 4/4. Messaging distinguishes career changers, experienced business people and existing specialist firms seeking conversion, linking the proposition to different learning and operational needs.
  • Ownership enquiry journey: Yes, 4/4. The published route moves through consultation, head-office discovery, commitment deposit, local research and business planning, financing, agreement, preparation and opening.
  • Pre-acceptance discovery: Yes, 4/4. Before agreement, the discovery day includes financial explanation and speaking with existing owners, followed by local business planning and funding. Those are concrete mutual decision stages.
  • Ownership go-to-market plan: Partially, 1.5/3. A dedicated ownership site, local opportunity pages and franchise directories demonstrate promotion. A complete current ownership marketing plan with scheduled channels and measures was not verified.
04 Grow Weak Foundation5/20

Grow: Named target areas and a defined network provide meaningful geographic direction. Current monthly ownership demand, suitable-source comparisons and signing conversion were not verified.

  • Monthly ownership enquiries: No public verification, 0/5. No current recurring monthly ownership enquiry series was verified. Daily customer leads described by an operator concern property-care clients rather than prospective franchisees.
  • Enquiry sources and best prospects: No public verification, 0/4. No current franchise-applicant source-to-qualification or best-owner comparison was verified. Customer search campaigns and CRM access do not establish ownership-source effectiveness.
  • Ownership conversion: No public verification, 0/4. No actual current ownership enquiry-to-franchisee conversion rate was verified. Branch numbers and selected signing stories provide no applicant denominator.
  • Next territories: Yes, 3/3. The network page names potential areas including Bristol, Oxford and Swansea, and a Reading opportunity describes a trading-area takeover. These are specific geographic expansion routes, subject to availability checks.
  • Consistent recruitment without founder-driven conversations: Partially, 2/4. A named franchise-management route and wider support team indicate some delegation. Consistent recruitment without current principal involvement throughout applicant conversations was not established.
05 Amplify Strong14.5/20

Amplify: Local pages, initial search campaigns and practical marketing channels support customer acquisition. Universal current owner coverage, continuing plans after the initial period and complete commercial reporting remain partly evidenced.

  • Local customer acquisition support: Yes, 5/5. The package describes local pages, initial SEO and paid search, direct email, social activity, leaflets and networking. This supplies practical support for local customer enquiries.
  • Every owner represented online: Partially, 2/4. Named branch pages and local survey contact routes are visible. Complete current coverage against every contractual owner and multi-area operator was not independently reconciled.
  • Continuing local marketing plan: Partially, 2/4. Regular advice and marketing assistance beyond opening are described, but the explicit free campaign period is three months. A complete continuing local plan and its funding after that period were not verified.
  • Individual owner enquiry and performance tracking: Partially, 1.5/3. A central CRM and an owner’s booking-and-lead system support measurement. Complete current owner-level source attribution, survey conversion, job margin and commercial reporting were not established.
  • Customers beyond personal networks: Yes, 4/4. Local search pages, paid campaigns, survey enquiries and commercial relationships offer customer routes beyond mainly referrals, personal contacts or direct founder selling.
67/100 Overall Five Fibre score

Five Fibre score: 67/100. Assess 13/20, Build 16/20, Launch 18.5/20, Grow 5/20, Amplify 14.5/20.

Prokil receives an overall Five Fibre score of 67/100, within the Growth Ready band. Its public strengths are a clearly explained territorial opportunity, substantive technical and business preparation, documented brand guidance and a detailed joining process. The main limitations concern verified financial outcomes and the measurement of ownership recruitment. The assessment distinguishes customer demand for property care from demand to buy a franchise.

  • Grow priority: measure the ownership journey independently of local survey enquiries. Named opportunity areas and an established network indicate expansion activity, but current monthly applicants, source quality and signing conversion were not verified. Follow suitable candidates through consultation, discovery, business planning and agreement, then connect their acceptance with subsequent local performance. A customer lead arriving through the CRM is a different measure from a qualified prospective owner.
  • Assess priority: establish realistic owner profit alongside turnover. Selected material describes a Brighton business turning over more than £650,000 and an owner whose earnings increased. That is useful attributed experience, but it is not a representative current P&L. Survey capacity, technician utilisation, materials, travel, office costs, marketing, central charges and remedial obligations all affect the amount an owner can retain.
  • Amplify priority: connect launch marketing with a continuing local customer plan. The package specifies an initial period of search and paid promotion plus local assets and practical channels. Clarify what continues after the free period, who funds it and how results are measured. Track suitable enquiries through survey, quotation, accepted work, delivery and contribution rather than judging campaigns only by lead volume.
  • Build priority: make the whole operating method accessible and current. Practical training, brand guidance and CRM updates provide substantive support. A complete current owner playbook and one reliable route to all tools and documents remain less visible publicly. Owners need consistent answers about surveying, scheduling, quotations, staff, customer communication and quality assurance as well as technical delivery.
  • Launch priority: retain the thorough discovery route and keep the information around it aligned. Candidates are offered a head-office visit, financial discussion, conversations with owners and help researching and planning their own area. Those are useful decision stages. The next improvement is a coherent current explanation of the package, training timetable, qualification expectations, availability and post-launch support for the particular opportunity.

Prokil’s current first-party network page describes twenty-three branches including Bournemouth head office, while other pages use broader wording such as more than twenty locations. Neither figure should simply become a count of independent franchise owners. The partner photograph includes several people associated with the same local area, as well as central staff. Towns, branches, territories and contractual ownership groups are different denominators.

The published history traces the first operation to Jim Thorne in 1965 and describes a transfer to Carlo Marsango in 2010, followed by Alex’s involvement in franchise development. This supports a model capable of continuing under successor leadership. It does not independently establish that current central operations can run for a month without daily principal input. The company’s incorporation date is also separate from the brand’s original trading history and later franchise development.

The owner cases offer more substance than a generic success headline. Simon’s Brighton account describes moving from branch management to ownership in 2021 and then expanding staffing and turnover. Neil and Colette’s account describes operating across a larger Kent and East Sussex area, adding technicians and vehicles, and managing remotely during part of a summer. These are selected, undated narratives, not a representative current performance census or proof that every owner can work remotely from launch.

Their starting positions also matter. An experienced branch manager taking over a trading business has different risks and capabilities from a newcomer opening an undeveloped territory. An established couple expanding an area is not the same case as a single new owner. The assessment recognises transferability and support without assuming identical ramp-up time, financial results or workloads across those routes.

The recruitment process is unusually clear. A consultation leads to a head-office discovery visit, including financial explanation under an NDA and contact with current partners. A commitment deposit precedes further local research and business planning, with the agreement following finalised planning and finance. The published sequence is recorded as the brand’s process. No deposit or agreement was submitted, and the precise refund and contractual terms were not independently inspected.

The first-party financial example identifies a franchise fee from £38,000 plus VAT, working capital and other setup costs, alongside a stated total and minimum initial contribution. The displayed components separate the franchise fee from total setup capital, while another directory retains a different package fee. A dated itemised quotation is needed to establish the terms of the actual opportunity. Finance availability remains subject to individual approval, not guaranteed access to borrowed capital.

Training information also has different levels of detail. The general offer describes around three months of preparation and beginning local work after approximately eight weeks, while an owner case describes an eight-week experience. Those may refer to different phases, backgrounds or historical programmes. They should not be presented as a single fixed timetable. Published qualification support and examination fees are also distinct from guaranteeing that every candidate passes or that every branch holds the same accreditation.

That accreditation distinction is independently material. The Property Care Association’s Prokil listing explicitly notes that it is a franchise operation and not all branches are members. A central membership statement therefore cannot be extended automatically across the network. This does not establish that non-member branches are incapable or that their staff lack training. It means customers and potential owners need branch-specific evidence for the claim being made.

Local customer routes are visible through dedicated branch pages and survey enquiries, supported by marketing and branding material. The explicit free in-house campaign access is time-limited, while the broader offer describes continuing support. The assessment gives credit for the practical acquisition platform but does not infer an indefinitely funded local campaign or full source-to-profit dashboard from a CRM reference alone.

The score reflects a developed proposition and operational support with commercial measurement still incompletely verified in public. Missing evidence does not mean those capabilities are absent internally. The useful next connection is between the right owner, a realistic territory plan, consistent technical delivery and profitable local work, supported by evidence from the actual current package rather than headline turnover or network age.
