Solar leads in the UK cost £20 to £35 each. Heat pump leads cost £40 to £80. Both numbers are rising. For a renewable energy company running on installer-style margins, digital marketing is no longer a brand exercise. It is the difference between a full diary and a quiet phone, and the operators who treat clean energy marketing as a measured lead engine, not a logo-and-strapline job, are the ones taking share.
Why renewable energy companies need a different marketing approach
The renewable sector behaves nothing like a normal home-improvement vertical. Buying cycles range from three weeks for an EV charger to nine months for a domestic solar plus battery install. Prices range from £1,500 for a basic charge point to £14,000 for solar with storage, and £15,000 plus for an air-source heat pump retrofit with a Boiler Upgrade Scheme grant. Customers pre-qualify themselves online with a depth other verticals never see. They check MCS status, read three or four installer reviews, run their own payback calculations, and only then submit an enquiry. A marketing strategy that does not match this rhythm wastes 40 to 60 per cent of its paid spend on enquiries that were never going to convert. The strategy that wins keeps technical depth on every commercial page, treats MCS certification as a primary trust signal, and accepts that the lead is half-baked until a phone or in-home survey has happened.
Six channels that move the needle for UK renewable installers
1. Google Ads on technology-specific search terms
Exact and phrase match on "solar panel installer [city]", "air source heat pump quote", "EV charger installation". Broad match excluded until the account has a mature negative list. Negative keyword lists running into the hundreds, blocking grants-only, DIY, and salary queries. Expect cost per click of £8 to £18 for solar, £12 to £25 for heat pumps, and a cost per qualified lead of £25 to £55 with a tight landing page. Well-run search is the fastest route to a predictable diary, which is why our Google Ads management work starts with the negative list before it touches bids.
2. SEO around postcode-level service pages
National "solar installer UK" pages do not rank for installers without a national van fleet. County and city-level service pages, "Solar Installers Manchester", "Heat Pump Installation Bristol", outperform generic ones by a wide margin. Local pack visibility is the second prize and worth fighting for. Consistent, technically-sound SEO compounds in this sector because the buyer research window is long enough for organic to do real work.
3. Meta and TikTok for demand creation
Most UK homeowners do not search for a heat pump until something prompts them. Energy bill shock, a neighbour's new install, a press headline about the Boiler Upgrade Scheme. Paid social plants the seed weeks before the search happens. Video walk-throughs of a finished install convert better than studio creative, and a homeowner testimonial shot on a phone usually beats a polished brand film.
4. Lead-gen forms with technical pre-qualifiers
Two-step enquiry forms that ask roof orientation, property age, and current heating system filter out 30 to 40 per cent of unqualified leads before they hit the sales pipeline. The cost per click stays the same. The cost per appointment drops sharply. This single change is often worth more than any bid adjustment.
5. Review platforms and trade-body badges
Trustpilot, Checkatrade, and MCS certification badges on every page. RECC, HIES, or NICEIC where applicable. Manufacturer-accredited installer status, Tesla, Octopus, Panasonic, Vaillant, displayed with the partner's actual logo. Buyers spending £10,000 of personal capital read trust signals before product detail.
6. Email and nurture for the long buying window
For solar and heat pumps, the median enquiry-to-install gap is 45 to 90 days. A short five-to-seven email nurture sequence, paired with one or two phone follow-ups and an in-home survey offer, recovers 15 to 25 per cent of enquiries that would otherwise go cold. Skipping this step is the single most common revenue leak in the sector.
Solar lead generation: what actually fills the diary
Solar lead generation in 2026 is split between two channels that genuinely produce, paid search and paid social, and a long tail of platforms that promise installer leads and rarely deliver economic ones. The arithmetic is straightforward. A £6,500 average residential solar install at typical UK installer margins gives a working maximum cost per acquired install of around £300 to £450. That implies a working maximum cost per qualified lead of £40 to £60 if the close rate sits at the sector average of 12 to 18 per cent. Anything above that range is a profit problem. Anything below is a scaling opportunity. Most installers underestimate how quickly cost per lead climbs as they push beyond the high-intent search audience, which is small and finite, into broader demand-creation. The honest answer is that the first £3,000 of monthly spend is usually the most efficient your account will ever run. Past that, each additional £1,000 needs a measurement layer that catches drops in close rate before they eat the margin gain from extra volume.
It is worth being blunt about the size of the pure search prize. "Solar lead generation" draws roughly 260 UK searches a month and "solar installer leads" around 140, both at cost-per-click figures north of £13 because everyone bidding is chasing the same finite pool. Digital marketing for solar companies cannot be built on head-term search alone. The volume simply is not there. The accounts that scale past a few installs a week do it by pairing that small, expensive, high-intent layer with demand creation on paid social and a content layer that catches buyers earlier, before they know which technology they want.
Heat pumps: a marketing problem with a policy tailwind
Heat pump marketing in the UK runs on different fuel. The Boiler Upgrade Scheme, currently offering £7,500 toward an air-source heat pump installation, dramatically shifts the unit economics for end customers but creates a marketing problem for installers. Awareness of the grant has climbed faster than awareness of what a heat pump actually is or how it differs from a gas boiler. The result is enquiry volume that looks healthy on paper and converts poorly on the phone. Installers winning in this segment over-index on educational content, particularly heat-loss-survey-led calculators and clear MCS plus grant explainers. According to the UK government's Boiler Upgrade Scheme guidance, the grant is paid via the MCS-certified installer, not directly to the consumer, which means a credible MCS status is both a compliance requirement and a marketing asset. Pages that lead with grant amount and bury MCS status convert worse than pages that lead with both equally.
Deployment data is worth watching as a demand signal rather than a vanity chart. The government publishes running figures in its household energy efficiency national statistics collection, and the regional spread in those numbers is a better guide to where a regional installer should buy media than any keyword tool. If certified installs in your counties are climbing while your enquiry volume is flat, the problem is visibility, not market size.
Battery storage, EV and commercial clean energy: the wider mix
Solar and heat pumps get the headlines, but the fastest-moving clean energy marketing budgets in 2026 sit either side of them. Domestic battery storage is increasingly an add-on sale rather than a standalone one: the marketing job is to raise attach rate on existing solar enquiries with payback-and-resilience messaging, not to run cold campaigns for "battery" as a term almost nobody searches. Domestic EV charger installations are a high-volume, low-margin business where speed of response wins. The website has to keep up with that: domestic, workplace and destination charging are three different buying journeys, and our low-carbon and EV web design service builds a separate route for each rather than funnelling all three through one contact form. Lead-to-quote response times under one hour produce noticeably better close rates than response times over four hours, so the marketing spend is wasted unless the sales process behind it is quick.
Commercial clean energy is a different animal entirely. Rooftop solar for warehouses, battery storage for SMEs, fleet EV infrastructure, and small wind projects move on tender cycles and procurement processes that bear no resemblance to consumer marketing. The right channel for a commercial PV brief is rarely paid search. It is more often LinkedIn account-based marketing, industry-association sponsorship, and direct outreach backed by case studies. Trying to run the same digital marketing playbook across domestic and commercial segments is the single most expensive mistake we see energy companies make. The winning approach treats them as two businesses that happen to share a brand.
Clean energy digital marketing: content and trust for eco-conscious buyers
Search demand around clean energy digital marketing and digital marketing for energy companies is growing faster than the narrow "solar installer" terms, because more buyers now start with the outcome (lower bills, lower carbon) rather than the product. That shift rewards content. A renewable energy company that publishes honest payback examples, real install walk-throughs, and plain-English explainers on grants and MCS earns the kind of trust a paid ad cannot buy, and increasingly earns citations in AI-generated answers where buyers now do early research. The examples that work are specific: a named town, a real system size, an actual annual saving, a photograph of the finished job. Generic "go green" copy ranks nowhere and converts worse. Treat educational content as the top of a funnel that paid search and email then close, and the whole account gets cheaper to run over time.
One structural warning about this part of the market. If you search clean energy digital marketing or digital marketing for renewables in the UK, page one is almost entirely agency sector pages: dedicated "renewable energy marketing agency" landing pages built to be hired, not read. That tells you something useful about your own site. If you want to be found by commercial searchers in the energy sector, a blog article is the wrong shape of page. A proper sector or service page, with pricing signals, proof, and a clear enquiry route, is what that search result set rewards. Blog content earns the informational long tail. Service pages earn the commercial head terms. Most energy brands publish plenty of the first and almost none of the second, then wonder why the traffic never converts.
Content marketing for energy brands: what to publish and in what order
Content marketing for energy businesses fails for a predictable reason. Teams start with the thing that feels most like marketing (a blog about sustainability) and skip the thing that actually gets read (an answer to the question a buyer typed at 10pm). Reverse the order. There is a rough sequence that works across the solar, heat pump and EV segments alike.
- Cost and payback pages, first. "How much does a heat pump cost in [county]", "solar panel payback UK", "is a battery worth it with an existing array". These carry the clearest buying intent of any content you will ever publish. Use real numbers from your own completed jobs, not manufacturer marketing figures.
- Eligibility and grant explainers, second. Boiler Upgrade Scheme qualification, MCS requirements, what a heat loss survey involves, what disqualifies a property. These pages catch buyers mid-decision and pre-qualify them before they ever reach your form.
- Technology comparisons, third. Air source against ground source, hybrid against full replacement, string inverter against microinverters. Comparison content is where AI answer engines pull from most heavily, so structure it with clear headings and plain factual statements.
- Named case studies, fourth. A town, a system size, an installed cost, an annual saving, photographs. One genuine case study outperforms ten opinion pieces, and it is the only content type that a prospect will read end to end.
- Sector commentary, last and least. Policy round-ups and industry-trend pieces are for credibility and press, not for lead generation. Publish them when the first four are done, not before.
The measurement rule for energy digital marketing content is simple: if a page has not produced an assisted conversion in six months, it is a brand asset, not a marketing one. Keep it if it earns links or citations. Rewrite it if it does neither.
Measurement that holds up at month end
The metric stack for a serious renewable energy marketing operation has three layers. Cost per qualified lead, by technology and channel, refreshed weekly. Lead-to-install conversion rate, by sales rep and by source, refreshed monthly. Margin per installed kW or per installed kit, refreshed at month end. If your CRM cannot give you the second layer, the problem is the CRM, not the marketing. According to ONS environmental accounts data, UK low-carbon and renewable energy economy turnover has been climbing year on year, but the gain is not evenly distributed. Installers that measure carefully take a disproportionate share. Those that do not are competing on price, which is the one competition nobody in this sector wins for long.
What to hold a renewable energy marketing agency accountable for
Plenty of agencies now list clean energy as a sector. Fewer can show what they changed and what it did to cost per install. If you are appointing help, the shortlist question is not "do you work with energy clients" but "what will you report, how often, and what happens if the number moves the wrong way". Four things are reasonable to insist on.
- Cost per qualified lead as the headline metric, not cost per click or impressions. Qualified means it passed your pre-qualification criteria, not that a form was submitted.
- Technology-level reporting. A blended figure across solar, heat pumps and EV hides the segment that is quietly losing money. Insist the split is visible.
- Access to the accounts you pay for. Google Ads, Meta, analytics and the CRM connection should be in your name. Agencies that hold accounts hostage are telling you something.
- A stated review point. Eight to twelve weeks is a fair first judgement window for paid search in this sector. Agree it up front so neither side is negotiating the goalposts later.

Frequently asked questions
What is a reasonable monthly marketing budget for a UK solar installer?
A regional installer doing 8 to 15 installs a month should expect to spend £4,000 to £8,000 on paid media plus £1,500 to £3,000 on tooling, retainer, and content. Below £3,000 monthly paid spend, paid search rarely produces enough lead volume to optimise on. Above £15,000 monthly, additional spend usually needs a second channel or a second geography to scale efficiently.
Are lead-aggregator platforms worth using?
Sometimes, briefly. Aggregator leads typically cost £15 to £25 but close at 3 to 7 per cent because the same lead is sold to three to five installers. They can fill a quiet week but should not be a primary channel. Cost per install almost always lands higher than well-run direct paid search.
How important is MCS certification for marketing?
Critical. MCS certification is a compliance requirement for Boiler Upgrade Scheme work and a buyer trust signal for solar and heat pumps in general. Sites that display MCS status, the certificate number, and the certifying body convert visibly better than sites that do not. Treat it as on-page real estate, not a footer afterthought.
What counts as clean energy marketing, and is it different from solar marketing?
Clean energy marketing is the broader umbrella: solar, heat pumps, battery storage, EV charging, and small-scale wind, marketed together under an outcome-led message about lower bills and lower carbon. It matters because a rising share of buyers search the outcome before the product. In practice you still run technology-specific campaigns underneath, but the brand and content layer speaks to the whole clean energy proposition rather than one product line.
Is digital marketing for energy companies different from digital marketing for installers?
Yes, and conflating the two wastes money. An energy supplier or developer is selling a contract or a project to a procurement process, so the work is brand, PR, LinkedIn and account-based outreach with a sales cycle measured in quarters. An installer is selling a job to a household, so the work is paid search, local SEO and speed of response, with a cycle measured in weeks. The two need separate budgets, separate reporting and usually separate pages on the site.
Does YouTube advertising work for renewable energy companies?
For demand creation, yes, in disciplined formats. Bumper ads under six seconds and skippable in-stream ads under 30 seconds, both with a clear local-installer message, can produce measurable lift on branded search volume within two to four weeks. For direct response, YouTube rarely beats search or Meta on cost per lead.
How long before a paid-search account stabilises for a renewable installer?
Eight to twelve weeks. The first four are spent gathering negative-keyword data and pruning the obvious irrelevant traffic. The next four to eight are spent reallocating budget to the technologies and postcodes with the best lead-to-install ratio. Installers that judge campaigns by month one almost always cut spend on campaigns that would have produced.
Should I run separate websites for solar, heat pumps, and EV chargers?
Usually no. A single brand with strong technology-specific service pages outperforms three thin micro-sites in nine cases out of ten. The exception is when one technology represents a clear majority of revenue and a different audience. In that case, a focused domain can outperform. Most multi-technology installers should consolidate, not fragment.
