Installer guide · updated 10 Nov 2026 · 19 min read
Short answer: a renewable energy marketing agency helps renewables businesses (solar installers, battery storage and EV charging firms, electrical contractors moving into renewables, developers) win customers. Some build the brand: website, SEO, PR and ads. Others generate leads and book meetings. TNW Marketing is a UK renewables marketing agency of the second kind, with one specialism: we book exclusive, pre-qualified commercial solar site surveys with the decision-maker for renewables businesses that install solar. We do not market heat pumps, roofing, wind or domestic solar, and we do not sell or install anything ourselves.
Pricing: £250 to £1,000+VAT per attended appointment, set by system size and qualification. No retainer, no monthly fee. You only pay for appointments that are actually attended, and any that aren't viable we replace.
A renewable energy marketing agency helps installers of solar, roofing, heat pumps and similar systems win customers. The name covers two quite different jobs. A full-service agency builds your brand: website, SEO, social media, content and paid ads. It is paid to create attention, and turning that attention into site meetings is left to your team. A lead generation agency does the opposite end of the work: it finds the businesses that are ready to talk, qualifies them and hands you an enquiry or, better, a booked meeting.
TNW Marketing is the second kind. We do not build websites or run brand campaigns. We do the prospecting, the calling and the qualifying, and the output is a site survey with the decision-maker at a business that can actually go ahead. If you install solar and want the solar-specific detail, including the channels that win commercial work, read our guide to choosing a solar marketing agency.
Good renewables marketing starts from the market it sells into. Solar is the part of UK renewables where most installers compete for business customers, and the official figures show why the work is there. Each figure is from the Department for Energy Security and Net Zero (DESNZ), as set out with every table on our UK commercial solar market guide.
For a renewables business that means two things. The buyers who matter most are businesses: the 10 kW to 5 MW bands are where commercial rooftops sit, and those sites are larger and fewer than homes. And the message that moves them is the electricity bill, which for non-domestic users has nearly doubled since 2019. A renewable energy marketing agency worth paying should be able to put both in front of the person who signs off the spend. More figures, by size band and region, are on our UK commercial solar statistics page.
Renewable energy marketing services, and marketing services for clean energy companies in general, come in five kinds. They differ in what you get at the end of the month and how much work is left for your own team. Here is what each one gives you, and which one TNW Marketing does.
| Service | What you get | Does TNW do it? |
|---|---|---|
| Website and SEO | Getting found when a business searches for solar | No |
| Paid ads (Google, Meta, LinkedIn) | Paying for clicks and form fills | No |
| Content, social and email nurture | Staying in front of prospects until they are ready | No |
| Pay per lead | An enquiry with contact details, for your team to call | No |
| Appointment setting | A site survey booked with the decision-maker | Yes: commercial solar only |
Most installers who want a predictable flow of commercial work end up paying for the last row. If you would rather buy solar leads, our UK comparison of providers lists what to check before you pay.
If you are comparing energy marketing companies, the first split is between agencies that build your brand and inbound marketing and agencies that hand you meetings. These are the renewable energy marketing agencies on page one of Google UK for this search on 2 November 2026, described from their own pages. It is not a ranking: each suits a different need, and only one of them prices per appointment.
| Agency | What it sells | Price on its page |
|---|---|---|
| Floom Creative | A London creative agency for renewable brands: branding, content creation and marketing campaigns, with SEO and Google and Meta ads among its featured solar work. | Not published |
| Phantom Digital | A solar digital marketing agency: SEO, website design, graphic design, social media, email marketing and content creation. | Not published |
| Solvi Digital | A UK marketing agency for renewables and utilities: strategy, brand identity, websites, Google Ads, SEO, LinkedIn and social, email, and installation photography and video. | SEO "typically starts from £1,000 to £3,000 per month", PPC management on top of ad spend, full-service retainers scoped per client |
| twentytwo & brand | A renewable energy marketing partner for solar, energy storage, EV, RNG and wind brands: branding, PR, social media, creative and website development. | Not published |
| TNW Marketing (us) | Commercial solar only: we prospect, call and qualify businesses and book exclusive site surveys with the decision-maker into your calendar. No websites, SEO or ads. | £250 to £1,000+VAT per attended appointment, no retainer, no minimum |
Read from each agency's own page on 2 November 2026; confirm services and fees with them directly. A brand or inbound agency is the right call when you want a website, search rankings and a recognisable name; a lead generation agency is the right call when the gap is booked meetings with businesses that can sign. Many installers use one of each. If what you need is booked commercial surveys rather than marketing, our comparison of solar lead providers covers the other side of the market.
The two names sound alike but sell different things. A sustainability marketing agency (also called a green or sustainable marketing agency) mostly helps organisations talk about their own environmental commitments: PR, brand, content and campaigns, often for consumer brands. When we checked Google UK for “sustainability marketing agency” on 10 November 2026, page one was PR, communications and consultancy firms of that kind. A renewable energy marketing agency sells renewable energy itself (solar, battery storage, EV charging, heat pumps) to the businesses and households that will buy it. If you install renewables, it is the second you need.
Whichever you hire, the rules on green claims apply to your marketing, not just theirs. The Competition and Markets Authority's Green Claims Code (published 20 September 2021) sets six principles:
For ads, section 11 of the CAP Code (Environmental claims) adds that “The basis of environmental claims must be clear” and “Absolute claims must be supported by a high level of substantiation.” For a solar installer, that means a saving, payback or carbon figure in a proposal or an ad should come from the site's own energy data, not a national average. Every TNW booking comes written up with the business's energy usage, bill spend and likely system size, which is the data those figures need.
If you searched for a marketing agency for green energy, be clear on this before you call us: we are specialists, not generalists. Our clients are UK commercial solar installers, and our work is commercial: businesses, farms, care homes, NHS and other larger sites rather than homeowners. We book commercial solar appointments only. If you install heat pumps, wind turbines, EV chargers or domestic solar, a general green energy agency will serve you better. The same commercial building often needs more than solar, though: some of the sites we book also need a roof replacement or overcladding first, which is where roofers come in.
Battery storage comes up on many commercial solar jobs too. Get Zero's biggest close from our leads was a 75kWp on-roof system with a 100kWh battery, and Harvest Green Developments, who specialise in commercial solar, battery storage and EV charging, layer storage into systems averaging 140 to 150kW. Both interviews are in our case studies.
Renewable energy inbound marketing means getting found: SEO, paid ads, content and social, so that businesses come to you. It builds an asset over time, but it is slow, and commercial decision-makers rarely fill in a solar quote form on a whim. Our sister site Solar Surveys UK has guides to solar SEO and solar advertising if that is the route you want.
Outbound means going to the businesses yourself, by phone, email and LinkedIn, and it is what reaches the person who signs off the spend. It is also the work most installers do not have the time or the staff for. Our guides to cold calling, cold email and LinkedIn show what each takes in house, and in-house vs outsourced lead generation sets out the real cost of a setter of your own.
The real difference between renewable energy marketing services is what you are paying for, and who pays when a month produces nothing.
| Compared on | Retainer marketing agency | Pay per attended appointment (TNW) |
|---|---|---|
| What you pay for | Time: a monthly retainer, often plus ad spend | Qualified, attended site surveys |
| What arrives | Traffic, followers and form fills your team has to call | A meeting in your diary with the decision-maker |
| Who works the enquiry | Your team calls, qualifies and books | We prospect, call, qualify and book |
| A quiet month | Costs the same | Costs nothing: no booking, no bill |
| Best for | Brand, website and long-term inbound demand | A steady flow of commercial surveys now |

TNW Marketing (formerly TNW Energy) is a UK lead generation agency for commercial renewables installers, founded by Daniel Bell and Roman Steer-Love. You pay for qualified, attended surveys, not for our time.
See how we qualify commercial leads, and use the lead calculator to work out how many surveys your install target needs.
Our clients are not only solar installers. They include battery storage and EV charging firms, electrical contractors moving into renewables, a power plant developer and a long-standing rural renewables company. What they have in common is that each one builds or installs commercial solar, and each buys commercial solar site surveys from us. Every result below is from a recorded interview with the business, and each links to the full case study. We have 42 recorded video testimonials in all on our reviews page.
“The leads passed to us: the people are interested in solar. We've won work out of it.”Read the Ingeni Renewables case study
“It short circuits the sales process: we're not waiting 12-24 months to get clients ready”Read the Harvest Green case study
“Better than an in-house sales person”Read the IndyGen case study
“Communication is bang on and they improve based on our recommendations”Read the Rural and Country case study

Our comparison of UK solar lead generation companies puts 15 suppliers side by side on these points, and appointment setting for solar installers covers the UK rules on business calls and email. Before you pay for any leads, read exclusive vs shared solar leads on how to check an exclusivity claim, and what commercial solar leads cost for every price UK suppliers publish.
Yes, with one specialism: commercial solar. We book exclusive, pre-qualified commercial solar site surveys for UK installers. We do not market heat pumps, roofing, wind, EV charging or domestic solar, and we do not sell or install solar ourselves.
It helps renewable energy installers win customers. A full-service agency builds your website, SEO, social media and ads and leaves your team to turn the enquiries into meetings. A lead generation agency such as TNW Marketing does the prospecting, calling and qualifying itself and books site surveys straight into your calendar.
UK commercial solar installers. We book commercial solar appointments only. Some of those sites also need a roof replacement or overcladding before panels can go on, which roofers working alongside solar installers can quote. We work for installers only and do not sell or install anything ourselves.
Full-service agencies usually charge a monthly retainer, often with ad spend on top: Solvi Digital, for example, says SEO for renewable energy companies typically starts from £1,000 to £3,000 per month, with PPC management on top of ad spend (its own page, 2 Nov 2026). Lead suppliers charge per lead. TNW Marketing charges £250 to £1,000+VAT per attended appointment, set by system size and qualification, with no retainer and no minimum spend. Compare any agency on cost per attended survey and cost per signed project, not on the monthly fee.
Usually in breadth. A renewables marketing agency tends to work across several technologies and kinds of client (solar, battery storage, heat pumps, EV charging, developers and clean energy brands) and sells renewable energy marketing services such as websites, SEO, PR, content and ads. A solar marketing agency concentrates on solar installers. TNW Marketing is narrower than both: we book commercial solar site surveys for installers. You only pay for appointments that are actually attended, and any that aren't viable we replace.
An agency that helps organisations market their sustainability: communicating environmental commitments through PR, brand, content and campaigns, often for consumer brands. On 10 November 2026 the top Google UK results for "sustainability marketing agency" were PR, communications and consultancy firms of that kind. A renewable energy marketing agency is narrower: it markets renewable energy itself (solar, battery storage, EV charging, heat pumps) to the people who will buy it. A renewables installer usually needs the second. TNW Marketing books commercial solar site surveys for installers and does not run sustainability PR.
Two sets matter in the UK. The Competition and Markets Authority's Green Claims Code (published 20 September 2021) says claims must be truthful and accurate, clear and unambiguous, must not omit or hide important relevant information, must make fair and meaningful comparisons, must consider the full life cycle of the product or service, and must be substantiated. For advertising, section 11 of the CAP Code (Environmental claims) says "The basis of environmental claims must be clear" and "Absolute claims must be supported by a high level of substantiation." For a solar installer, that means savings, payback and carbon figures should come from the site's own energy data.
No. We do not build websites or run brand, SEO or social campaigns. We do outbound prospecting and qualifying and hand you booked commercial site surveys. Many installers use an inbound agency for their brand and website and us for a predictable flow of commercial meetings.
Only for commercial solar installers. If you sell solar PV, often with battery storage, to businesses, farms and public-sector sites, we book your site surveys. If you install heat pumps, wind, EV chargers or domestic solar, a general green energy agency will suit you better, because we do not book those appointments.
No. Every booking is exclusive to one installer. A booking that does not go ahead, or does not meet the agreed brief, is replaced. Our show rate is 60%+.
Yes. TNW Energy is now TNW Marketing: the same team under a new name, still booking pre-qualified, exclusive site surveys for commercial renewables installers on a pay per attended appointment basis.
