Web design & marketing for renewables, solar & retrofit

Win trust and qualified enquiries in solar, retrofit and renewables

For solar installers, retrofit specialists, ECO-grant providers and decarbonisation firms.

Renewables is a trust-heavy, often-confusing purchase, for homeowners chasing grants and for commercial buyers planning decarbonisation. We build clear, credible websites and qualification funnels that turn interest into properly-qualified enquiries.

How we help

Your next steps

  1. 1 Audit We map your offer, your ideal customer and where enquiries currently drop out.
  2. 2 Build We build a credible site and a qualification funnel that guides people through.
  3. 3 Optimise We launch, measure qualification rates and keep improving conversion.

Challenges we solve

  • Complex, off-putting journeys Grant eligibility and technical detail lose people partway through. A confusing journey means qualified leads quietly drop out.
  • Trust is everything The sector is crowded and customers are wary of mis-selling. Your site has to establish credibility fast, for homeowners and B2B buyers alike.
  • Mixed-quality enquiries Too many unqualified leads waste your team's time. You need a funnel that filters and qualifies before the call.

Why it pays off

  • 60,000 certified heat-pump installations across the UK in 2024, up 43% on the year before (MCS)
  • 184,462 certified solar PV installations recorded in 2024 (MCS)
  • 260,000+ certified small-scale renewable installations in 2024, a record year (MCS)

Going deeper

Why digital works for renewables

Because almost nobody buys solar, a heat pump or a retrofit on impulse, they research it for weeks first, and most of that research happens online. They’re checking grant eligibility, comparing installers, reading up on how it all works and deciding who they trust before they ever fill in a form. If your website doesn’t answer those questions clearly and credibly, you lose them to a competitor who does.

The market gives you plenty to work with. Heat-pump installations and rooftop solar are at record levels, and government schemes like the Boiler Upgrade Scheme are pushing a steady stream of homeowners online to find a reputable installer. The demand is there. The hard part is being the firm those people find, trust and choose, and that’s a job your website and your search presence do for you, day and night.

That’s the difference a proper digital setup makes. A clear, credible website backed by content and SEO doesn’t just attract interest, it qualifies it. We build the journey so that by the time someone enquires, they understand what you do, they’ve checked their eligibility, and they’re a genuine prospect rather than a tyre-kicker. It’s the difference between a busy inbox and a profitable one.

What good looks like in this sector

A renewables site has two jobs: build trust fast, and filter as it converts. We design the qualification journey so eligibility and technical detail are handled step by step, not dumped on a single page that scares people off. We make your accreditations, real installs and clear pricing guidance do the reassuring. And we structure the whole thing so the enquiries that reach your team are worth following up, homeowners who qualify for a grant, or commercial buyers with a real decarbonisation budget.

It works for both audiences. For homeowners, the journey is about confidence and grant clarity. For commercial solar and retrofit, it’s an authority platform built for the people signing off the budget, clear value, easy to navigate, credible enough to be taken seriously in a procurement process. The principle is the same either way: answer the questions, remove the friction, earn the trust.

We’ve done exactly this. For DVC Group and Warm Homes Funding, an ECO-grant and renewables operation, we built the website and the systems behind it, and it drove over 2,000 organic leads in two years with no paid spend. That’s not paid traffic you have to keep topping up; it’s a search presence that brings the right enquiries in month after month, for free. You can see more of our work and the numbers behind it.

None of this needs jargon or a six-figure budget. It needs a clear site, an honest qualification journey and the SEO foundations to get found when people are actually searching. Get those three right and a research-heavy, trust-led sale stops feeling like hard work, because the website has already done most of it before anyone picks up the phone.

Commercial Solar & Retrofit

Renewables, Solar & Retrofit: your questions answered

Do you cover both domestic grants and commercial solar?

Yes. We built a streamlined grant-qualification funnel for an ECO-grants business (Warm Homes Funding) and a credible B2B platform for a commercial solar and retrofit specialist (DVCG). We work across domestic renewables, ECO grants, solar and commercial retrofit.

How do you improve the quality of renewables leads?

We design the journey to qualify as it converts, guiding people through eligibility or requirements step by step, so the enquiries that reach your team are genuinely worth following up.

Our offer is technical, can a website really make it credible?

That's the priority. In a sector where buyers are wary, a clean, authoritative site with clear value propositions does a lot of the trust-building before anyone speaks to your team, which matters for homeowners and corporate buyers alike.

Can you build for a commercial, B2B audience?

Yes. For commercial decarbonisation we build platforms aimed squarely at corporate decision-makers, clear, credible and easy to navigate, so you're taken seriously by the people signing off the budget.
