    Appointment Setting for Commercial Solar Installers

    Short answer: appointment setting is booking qualified sales meetings into your calendar, so your team spends its time surveying and selling rather than prospecting. For a commercial solar installer the meeting that matters is a site visit with the decision-maker at a business that owns its building (or has landlord consent), spends enough on electricity and has a roof or land that works. This guide covers how appointment setting services are priced, when to keep it in-house, what to ask an appointment setting company, and the UK rules on B2B calls and email.

    What appointment setting is (and what it is not)

    Appointment setting, sometimes sold as B2B appointment setting or sales appointment setting, is the work between "this business might be a fit" and "we have a meeting in the diary". A setter researches the prospect, gets through to the right person, checks they match your brief and books a meeting. The deliverable is a booked conversation with someone who can say yes, not a list of names.

    It overlaps with two terms you will see used loosely by every telemarketing company in the UK:

    TermWhat you receiveWhat it means for your team
    Appointment settingA meeting with a named decision-maker, booked into your calendarThe person who books it has already qualified the business
    Lead generationAn enquiry: a name, a number, sometimes a form answerYour team still calls, qualifies and books
    TelemarketingCalls made, conversations had (the activity, not the outcome)Can be used for appointment setting, surveys, data cleansing or selling

    B2B telemarketing is a channel; appointment setting is an outcome. A good appointment setting agency will use the phone, but also email, LinkedIn and paid ads to reach people who never pick up a cold call. For the wider picture of how commercial solar enquiries are generated, see our commercial solar lead generation guide.

    Why commercial solar appointment setting is different

    Most outsourced appointment setting in the UK is built for software, IT and consultancy sales, where a 30-minute video call is the goal. Solar appointment setting has to clear more hurdles before a booking is worth your surveyor's day:

    • The decision-maker is rarely the first person you reach. The owner, MD, finance director or facilities lead signs off capital spend. A meeting with an office manager who "will pass it on" is not an appointment.
    • Ownership decides everything. A tenant cannot put panels on a roof it does not control. The setter has to establish freehold ownership, or landlord consent and a lease long enough to make the project worthwhile.
    • Energy spend sets the size of the prize. A site with heavy daytime use is a different conversation from a lightly used unit. Bills and metering need to be understood before the visit, not discovered during it.
    • The roof or land has to work. Roof type, condition, space and shading, or space for a ground-mount, can end a project before it starts.
    • The sales cycle is long. Boards approve budgets, finance is arranged and some public-sector buyers go through formal procurement (our guide to commercial solar tenders and frameworks covers that route). The setter needs to judge genuine intent, not just politeness.

    Our checklist on how to qualify commercial solar leads goes through the questions in detail, and the UK commercial solar market in numbers shows where the demand sits.

    Appointment setting pricing models compared

    Appointment setting services are sold in four main ways. The headline price matters less than who pays for the work that does not turn into a meeting.

    ModelWhat you pay forWho carries the riskYour team still has toWatch out for
    Hourly or day-rate SDRCaller time, whatever it producesYouBrief, manage and judge every bookingActivity reports that look busy while the diary stays empty
    Monthly retainerA fixed fee for a campaign or teamYouChase results, then work whatever comes throughMinimum terms and vague definitions of an "appointment"
    Pay per leadEach enquiry deliveredMostly youCall, qualify and book every lead yourselfShared leads and enquiries that never reach a site visit
    Pay per appointmentEach qualified meeting that is booked (and, with TNW Marketing, attended)Mostly the providerTurn up, survey and sellLoose definitions of "qualified": get the brief in writing

    Rates for each model vary widely by provider, sector and how deep the qualification goes, so compare like with like: ask every supplier for the cost per attended appointment and, once you have run a few months, your cost per signed project. Our guide to what commercial solar leads really cost walks through that maths, and pay-per-lead vs retainer agencies compares the two older models in depth. If paying only for meetings appeals, read how pay per appointment solar leads work.

    In-house appointment setter vs outsourced

    Hiring your own setter or SDR gives you full control of the script, the data and the brand. It also makes you responsible for everything around the calls:

    • Recruiting someone who can hold a credible conversation with an MD about energy costs.
    • Training them on commercial solar: ownership and leases, metering, roof suitability, finance options.
    • Buying and cleaning data, and screening it against the TPS, CTPS and your own do-not-call list.
    • A dialler, CRM, email sending and LinkedIn tools, plus someone to manage activity and quality.
    • Ramp-up time before the first meetings land, and cover for holidays, sickness and leavers.

    For a salary benchmark, the nearest official job profile is the National Careers Service's sales representative, which gives an average of £23,000 a year for a starter to £50,000 for someone experienced, on 37 to 45 hours a week. Treat it as a rough guide: it is not specific to appointment setting, and employer costs, commission, data and software come on top. Whatever the figure, you pay it in a quiet month too.

    Outsourcing suits installers who would rather buy outcomes than build a calling team. It works best when the provider knows the sector and is paid for meetings rather than hours. Our comparison of solar lead generation companies lays out the main options.

    What a good booked commercial solar appointment includes

    Before you agree to any appointment setting service, agree in writing what a "booked appointment" means. For commercial solar, a good one has:

    • A written brief. Business name, site address, contact, energy usage and bill spend, roof or land details and the likely system size, so your surveyor arrives prepared.
    • Qualification checks completed. Ownership or landlord consent, energy spend, roof or land suitability and buying intent, each confirmed before booking.
    • The decision-maker attending. The person who can approve the spend, named in the booking.
    • A confirmed time in your calendar. In the areas you cover, at a time your team can make, confirmed with the prospect.
    • A clear no-show rule. What happens if the prospect cancels, does not turn up or turns out not to match the brief: replaced, refunded or charged anyway?
    • Exclusivity. You are the only installer booked into that site.

    How to judge an appointment setting company

    Questions worth asking any appointment setting agency before you sign:

    1. What exactly counts as an appointment, and do I pay if it does not take place?
    2. Who will I meet: the decision-maker, or whoever answered the phone?
    3. Which checks do you complete before booking, and can I see an example write-up?
    4. Are appointments exclusive to me, or offered to other installers too?
    5. Is there a retainer, minimum spend or minimum term?
    6. Do you work in commercial solar, or across any B2B sector?
    7. Which channels do you use, and how do you screen call data against the TPS and CTPS?
    8. What is your show rate, and how do you measure it?
    9. Can I speak to installers you work with, or see their results?

    An agency that talks only about dials and "pipeline" is selling activity. You can check our answers against our client results, the installer case studies and our video reviews.

    UK compliance basics for B2B calls and email

    Whoever does the calling, the rules come from the Privacy and Electronic Communications Regulations (PECR) and UK GDPR, and the regulator is the Information Commissioner's Office (ICO). The points below summarise the ICO's guidance at the time of writing; check the current version, and take advice for your own setup.

    Live B2B calls

    • You can make live marketing calls to a business without consent if the number is not on the TPS or CTPS and the business has not told you it objects to your calls.
    • Screen against both registers and your own do-not-call list. The ICO notes that sole traders and some partnerships register with the TPS, while companies, some partnerships and government bodies register with the CTPS.
    • The ICO says it can take 28 days for a TPS or CTPS registration to become active, and that if you buy a list described as screened, you should make sure the check was recent.
    • Say who is calling, display your number (or an alternative contact number), and give a contact address or freephone number if asked.
    • Automated calls that play a recorded message need the person's specific consent.

    B2B email

    • PECR's email marketing consent rule does not apply to corporate subscribers: companies, LLPs, Scottish partnerships and government bodies.
    • You must not hide who you are, and you must give a valid address so recipients can opt out. The ICO recommends keeping a suppression list of businesses that object.
    • Sole traders and some partnerships are treated as individuals, so you need consent or the soft opt-in.
    • An email to a named person at a company is still personal data under UK GDPR. They have an absolute right to object to direct marketing, and legitimate interests is often the appropriate lawful basis, subject to the ICO's three-part test.

    Appointment setting FAQ

    What is appointment setting?

    Appointment setting is booking qualified sales meetings for another business. The setter finds and contacts prospects, checks they fit the brief, and puts a meeting with the decision-maker into the client’s calendar. For a commercial solar installer, the meeting is usually a site visit or survey with the business that owns the building and pays the electricity bill.

    What is the difference between appointment setting and lead generation?

    Lead generation hands you an enquiry: a name, a number and sometimes a few form answers. Appointment setting hands you a booked meeting with someone who has already been qualified. With leads, your team does the calling, qualifying and booking; with appointment setting, the provider does it.

    Should I hire an in-house appointment setter or outsource?

    In-house gives you full control but means recruiting, training on commercial solar, buying data and software, screening against the TPS and CTPS and managing the role, with a salary paid whether or not meetings land. Outsourcing moves that work to a specialist. Paying per qualified appointment also moves the risk of an empty month to the provider.

    Is B2B cold calling legal in the UK?

    Live B2B marketing calls are allowed without consent if the number is not registered with the TPS or CTPS and the business has not told you it objects to your calls. The ICO says you must screen against both registers and your own do-not-call list, say who is calling, display your number and give a contact address or freephone number if asked. Automated recorded-message calls need specific consent.

    Can I send marketing emails to businesses without consent?

    Under PECR, the email marketing consent rule does not apply to corporate subscribers such as limited companies, LLPs, Scottish partnerships and government bodies. You must still identify yourself and give a valid address to opt out. Sole traders and other partnerships are treated like individuals, and emailing a named employee still involves UK GDPR, including their absolute right to object to direct marketing.

    How does TNW Marketing charge for appointment setting?

    TNW Marketing is paid per qualified, attended commercial solar appointment, with no retainer and no minimum spend. Bookings that cancel, do not show or do not match the agreed brief are replaced or refunded rather than charged.

    How many appointments does a commercial solar installer need?

    Work backwards from installs: divide the number of commercial installs you want each month by the share of site surveys your team converts. That gives the attended appointments you need. The TNW lead calculator does this for you.
