Solar Leads UK: Compare Providers and Pay per Appointment from £250

Eleven UK solar lead suppliers we found on page one of Google for solar lead searches in October 2026, plus TNW Marketing. Every competitor detail is from that company's own website, read on 23 Oct 2026. "Not stated" means the site does not say. Listed in no particular order, with TNW Marketing last.

Prices exclude VAT unless a supplier says otherwise. "Raw" means an enquiry you call and qualify yourself; "booked" means a meeting already in your diary. Sources for every row are in the supplier details below.

Most UK solar lead suppliers are built around homeowner enquiries. Of the eleven other suppliers we checked, four describe a homeowner or domestic focus (Capital Leads, GMS Leads, Boiler Guide and PoweredLeads), three sell to homeowners and businesses (Lead Pronto, Leads 2 Trade and Leads Everyday), two do not say (HelloClicks and Compare Solar), Royal Energy runs separate commercial and residential services, and Clean Energy Group describes itself as commercial. TNW Marketing is commercial only. Only two of the twelve publish a commercial price.

So the first question is not which supplier, but which kind of lead. A domestic installer can work volume: homeowner enquiries, often shared, priced per lead. A commercial installer needs fewer, larger opportunities where the business owns or controls the building, uses its electricity in the day and has a person who signs off the spend. If you are about to buy solar leads in the UK for commercial work, our explainer on how solar leads are priced sets out the pricing models and the checks to make before you pay, and the rest of this page compares the providers on them.

Buying solar leads is one way to fill a survey diary, not the only one. Most commercial installers win work from a mix of the routes below, and each puts the work and the cost in a different place. Knowing which routes you already have tells you what, if anything, is worth buying.

• Referrals and past customers

  Warm introductions from clients, landlords and other trades. Nothing to pay per lead, but they arrive when they arrive, so they rarely fill a diary on their own.

• Your own website, search and ads

  Businesses that find you and get in touch. Search takes time to build and ads pull in homeowners as well, so someone has to sort and qualify every enquiry. Our guide to solar installer marketing covers what an agency can do here.

• Your own outbound

  You pick the sites and contact them by phone, email or LinkedIn. It needs a list and a person with time every week; the prospecting guide shows how to build the list from public data.

• Public tenders and frameworks

  Schools, councils and NHS sites buy through formal procurement. The work is published, but bids take time you are not paid for and awards come in waves. See commercial solar tenders and frameworks.

• Partners: EPC contractors and funders

  Subcontracting to a larger contractor, or working with a funder that pays for the system, brings in projects you did not have to find. Our guides to solar EPC contracting and commercial solar PPAs explain both.

• Bought leads and booked appointments

  The route this page compares. You pay a lead seller for enquiries your team then works, or pay an appointment setter for a meeting already in your diary. It is the quickest of the routes to start and stop, and the price per lead or meeting is agreed before you begin.

If you decide to buy, the useful question is how much of the work between an enquiry and a signed contract you want to keep. The sections below take the products, the prices and the suppliers in that order.

"Solar installer leads" and "commercial solar leads" cover several different products, and suppliers price them very differently. A lead can be anything from a form fill shared with three other installers to a meeting that has already happened with the person who signs. Before you compare anyone, decide which of these you want.

1. 1

   Raw enquiry

   You receive: A form fill or call from a business, often shared

   Then: You call, qualify, book and confirm

2. 2

   Qualified lead

   You receive: An enquiry the supplier has phoned and checked against agreed criteria

   Then: You book and confirm the survey

3. 3

   Booked appointment

   You receive: A meeting in your diary; you may pay even if nobody turns up

   Then: You attend, survey and sell

4. 4

   Attended appointment

   You receive: A meeting that took place with the decision-maker; paid only when it happens

   Then: You survey and sell

5. 5

   Managed campaign

   You receive: Ads or outreach run in your name for a monthly fee or share of spend

   Then: You handle every enquiry it produces

✓

Ownership

Owned, or leased with time left and a landlord who will consent. No consent, no install.

✓

Electricity use

Rough monthly spend, meter type and how much is used in the day, which is what makes commercial solar pay.

✓

Roof or land

Material, age, condition and size, or land for ground-mount. A roof that needs replacing first changes the project.

✓

Decision-maker

Who signs off the spend, and whether they will be at the survey.

✓

Timescale and reason

Why now, and when they would want the system on: rising bills, a net zero target, a new building.

✓

Funding route

Cash, finance, lease or a power purchase agreement, if known. It changes the proposal you write.

Our commercial solar lead qualification checklist explains each check, and how to sell commercial solar covers what to do with the meeting once it is in your diary.

Source: DESNZ, Solar photovoltaics deployment in the UK (ET 6.3), Table 1, end of August 2026, published 29 September 2026. The bands also include some homes, farms and small ground-mounted sites.

There are about ten times as many systems in the smaller band, but the larger band holds twice the capacity on less than a tenth of the sites. So agree the size band in writing before you buy. A lead for a 15 kW roof and a lead for a 400 kW warehouse are not the same product, and a supplier that cannot tell you the expected system size, or at least the roof area and annual electricity spend, is selling you the qualifying work. The UK solar market in numbers breaks the figures down by band and region (the year-by-year tables, including how many 10 to 50 kW and 50 kW to 5 MW systems are installed each month, are on our UK commercial solar statistics page), and if you would rather find sites of the right size yourself, commercial solar prospecting from public data shows how to build that list.

Two suppliers in the comparison publish commercial prices. Lead Pronto lists commercial leads from £150 and booked appointments from £250, with the appointment price depending on area, criteria and the size of the job (read 23 Oct 2026); if you already buy from them, our Lead Pronto alternatives page compares six other suppliers on price, exclusivity and no-show terms. TNW Marketing charges £250 to £1,000+VAT per booked appointment, set by system size and qualification (bills, half-hourly data). Everyone else quotes on request, because the price depends on your area, the system sizes you want and how tightly the brief is drawn.

The sticker price is the least useful number. What matters is what each signed project costs you once you count the leads that never reach a site and the meetings that never become a contract:

A cheap enquiry that your team has to chase, qualify and book can cost more per signed project than a dearer attended meeting, and the reverse can be true if your own booking team is strong. Ask each supplier for its attendance terms in writing, then plug your own close rate into our lead calculator. Our guide to commercial solar lead costs walks through the sums, and pay per appointment explains the model where you pay only when the meeting happens. To put two quotes side by side in pounds per signed job, use the solar cost per lead calculator.

Lead generation companies in the UK use the same words for very different products. For a solar installer they fall into four broad groups, and many suppliers mix more than one.

• Lead sellers and networks

  They run websites and ads and sell the enquiries per lead, to one installer or several. Some phone each enquiry first; others pass on form fills.

• Pay-per-appointment providers

  They qualify the prospect and book a meeting into your diary, and you pay per appointment rather than per enquiry. Read our guide to pay per appointment solar leads for how the model works.

• Lead generation agencies

  A lead generation agency in the UK usually runs paid ads, landing pages or SEO in your name for a monthly fee or a share of ad spend. You own the enquiries and do the qualifying. See pay-per-lead vs retainer agencies for the trade-offs.

• Outbound appointment setters

  They research businesses that fit your brief, contact them by phone, email or LinkedIn and book meetings. More common in commercial solar, where the buyer is a business.

They suit different installers. Just don't compare a cheap domestic form fill with a booked commercial survey as if they were the same product.

Solar lead generation is the work of finding people or businesses who might buy solar and getting them to a conversation with an installer. The suppliers compared here use very different channels, and the channel decides how much intent a lead has when it reaches you. From what each says on its own site:

• Search, social ads and their own websites

  Lead Pronto (social ads, paid search and SEO), Capital Leads and Compare Solar (Google Search), Leads 2 Trade and Boiler Guide (their own websites, with phone qualification) and GMS Leads (online enquiries). The prospect came looking, or clicked an ad.

• Ads run in your name

  Leads Everyday builds you a landing page and runs Google Ads, and customers contact you directly. You own the enquiries and do the qualifying.

• Outbound to businesses

  Clean Energy Group (AI prospecting, B2B intent email campaigns and its own sales development representatives) and TNW Marketing (outbound calling, email, LinkedIn and paid ads, then a qualifying call). Royal Energy runs a commercial pipeline service but does not detail its channels on its homepage. The business may not have been looking until someone got in touch.

• Bought-in or shared data

  Not stated by most suppliers. Ask where every lead came from and what consent sits behind it, especially for anything you will call or email.

Commercial decision-makers rarely fill in a quote form on a whim, which is why outbound channels feature more in commercial solar. If you would rather run lead generation yourself, our guides to cold calling, cold email and LinkedIn for commercial solar cover each channel and the UK rules, and our guide to solar installer marketing explains when a full-service agency is the better buy than a lead supplier.

These are the rows of every company card below, in the order a commercial installer should weigh them.

1. 1

   Pricing model: per enquiry, per booked appointment, per attended appointment or retainer

   Paying per enquiry is cheapest per unit, but your team still calls, qualifies and books, and many enquiries never reach a site. Paying per booked appointment moves the booking work to the supplier, but you may still pay for meetings that do not happen. Paying per attended appointment means you pay only when the meeting takes place. A retainer or flat monthly fee pays for activity, whatever it produces. Our guide to what commercial solar leads cost shows why cost per signed project is the only fair comparison.

2. 2

   Exclusivity

   Ask how many installers receive the same lead. A shared lead is cheaper, but the customer may already have other companies on the phone. For commercial projects an exclusive meeting is usually worth more than several shared enquiries.

3. 3

   Commercial vs domestic focus

   Many solar lead suppliers are built around homeowners, ECO schemes or home improvement. A commercial installer needs warehouses, factories, farms, offices and schools, so ask for an example commercial write-up. If you buy solar leads in the UK for C&I work, read how solar lead pricing works first.

4. 4

   Qualification depth

   "Qualified" ranges from "the phone number works" to a full check of ownership, energy use, roof or land, the decision-maker and timeline. For commercial solar, ask who owns the building and who signs off the spend. Our commercial solar lead qualification checklist lists them.

5. 5

   No-show and replacement terms

   Every supplier has some bad leads and missed appointments. Good terms say what counts as valid, how long you have to report a problem, and whether it is replaced, refunded or credited. Get it in writing first.

6. 6

   Contract length

   Look for setup fees, minimum terms, notice periods and minimum spend. A short or rolling arrangement lets you stop if the numbers do not work.

7. 7

   How the leads are generated

   Leads come from search ads, social ads, the supplier's own websites, outbound calling, email, LinkedIn or data. Intent differs: a search enquiry is actively looking, an outbound prospect may not have been until someone called. Ask where the leads come from and whether data is bought in. Our solar lead generation guide compares the main channels.

A few patterns stand out. None makes one supplier right for everyone, but they show what to ask.

• Few publish prices.

  Lead Pronto and TNW Marketing are the only suppliers here that list commercial solar prices on their sites, and PoweredLeads publishes a domestic price. The rest price on request, so expect to compare quotes, and ask for them on the same basis (per lead, per appointment or per month).

• The product behind "solar leads" differs widely.

  Here you can buy a PIN-verified web enquiry, a phone-qualified lead, a live hand-over, a booked appointment, outbound meetings or a managed ad campaign. Compare like with like.

• Most are not commercial-only.

  Four suppliers state a homeowner or domestic focus, three cover both, Royal Energy runs separate commercial and residential services, and only Clean Energy Group and TNW Marketing describe themselves as commercial. If you install C&I systems, ask each one for an example commercial lead.

• Exclusivity is often a product choice.

  Some sell only exclusive leads; others sell exclusive and shared versions. Compare Solar and Boiler Guide offer each enquiry to up to three companies, and Leads 2 Trade's booked appointments go to up to three installers.

• Contracts are mostly short.

  Most suppliers that mention contracts state no long-term contract, a rolling monthly agreement or pay as you go. No-show and replacement terms are where they differ most, and five of the eleven do not state them at all.

Whether you are talking to a specialist solar lead provider or a general lead generation agency in the UK, put these questions to every supplier and get the answers in writing.

1. 1Do you generate commercial solar enquiries, or mainly homeowners? Can I see an example of a commercial lead or write-up?
2. 2Am I paying per enquiry, per booked appointment, per attended appointment, or a monthly fee?
3. 3How many other installers receive the same lead or appointment?
4. 4What exactly is checked before a lead reaches me: ownership or lease, energy spend, roof or land, decision-maker, timeline?
5. 5Who will I be meeting: the bill payer and decision-maker, or whoever filled in the form?
6. 6What counts as a valid lead or appointment, and what happens with no-shows, cancellations and wrong details?
7. 7How quickly must I report a bad lead, and is it replaced, refunded or credited?
8. 8Is there a contract, a minimum term, a notice period, a setup fee or a minimum spend?
9. 9Where do the leads come from: your own websites, paid ads, outbound calling, email, LinkedIn, or bought-in data?
10. 10Can I start with a small order and judge it on cost per signed project?

Then track every lead from enquiry to attended meeting, quote and signed project. Our free lead calculator works out how many attended appointments you need for your install target, and how many raw leads it would take to get the same surveys yourself.
