Web Design for Insulation, Retrofit and Low-Carbon Companies
Websites and search campaigns for the firms doing the actual decarbonisation work: insulation and retrofit installers, heat pump and solar engineers, EV charge point operators. Built around the two questions every one of your enquiries starts with: do I qualify, and what will it cost me?
What we do
-
Insulation and retrofit websites
Cavity wall, loft, internal and external wall, underfloor: each measure gets its own page, its own search terms and its own enquiry route. A single "Insulation Services" page listing eight measures in bullet points replaces eight ranking opportunities with one diluted one, and it is the most common structural mistake we see in this sector.
-
Eligibility-checker funnels
Most enquiries in funded retrofit die on the same question: am I eligible? A short, honest qualifier (tenure, property type, EPC band, income-related criteria) routes the visitor to funded or self-funded before anyone picks up a phone. It also stops your team burning hours on enquiries that were never going to convert.
-
EV charge point and heat pump sites
Domestic, workplace and destination charging are three different buyers with three different objections, and a heat pump enquiry needs a survey booking rather than a quote form. We build the site around the actual sales motion instead of forcing all of it through one contact page.
-
Accreditation and trust architecture
TrustMark registration, PAS 2035 and PAS 2030 compliance, MCS certification, NICEIC and competent-person scheme membership. In this sector accreditation is not a footer badge, it is the qualifying criterion for homeowners, for scheme administrators and for commercial procurement. It belongs on every page a buyer lands on.
-
Search and AI visibility
Technical SEO, structured data and the plain-language service definitions that decide whether an AI Overview or an assistant names your firm at all. Buyers in this sector increasingly start with "do I qualify for a grant" typed into a chatbot, and the firms getting quoted are the ones whose eligibility content is unambiguous.
-
Lead routing that survives a busy week
Enquiries split by measure, by funded versus self-funded and by region, landing in the right inbox or CRM with the survey information already attached. A form that dumps everything into one address is how a good month turns into a backlog of missed callbacks.
How we build a low-carbon website
No discovery theatre. The first two weeks are spent working out which measures actually make you money and which enquiries are wasting your team's time, because that determines the entire structure of the site.
-
Free audit (week 0)
We look at what you rank for now, which measures your enquiries actually come in for, where the funded and self-funded split sits in your pipeline, and how much of your team's week goes on unqualified enquiries. You get the findings whether or not you work with us, including the honest version where your existing site is fine and the problem is somewhere else.
-
Measure map and eligibility logic (weeks 1-2)
One page per measure, mapped against real search demand and against the jobs you want more of rather than the full list of what you can technically do. In parallel we design the qualifier: the smallest set of questions that reliably sorts funded from self-funded without making a homeowner feel interrogated.
-
Build (weeks 3-7)
WordPress, built for speed on a phone signal at a property rather than on office fibre. Accreditation surfaced at decision points, measure pages with real project proof, survey and quote routes separated, structured data throughout so search engines and AI assistants can read what you do and who qualifies.
-
Launch and search (week 8 onwards)
Redirect mapping first, because on a rebuild the fastest way to lose a year of rankings is to change URLs carelessly. Then measure-level SEO, technical fixes, and paid search where the funded-work seasonality justifies it. We report against enquiries by measure, not against traffic.
Why low-carbon websites lose work they had already won
The demand in this sector is not the problem. Insulation, retrofit, heat pumps and EV charging all have buyers actively searching. The problem is that most installer websites are built like a general trade site (a homepage, a services page, a gallery, a contact form), and that shape cannot answer the two questions that decide a low-carbon enquiry.
The first is eligibility. A homeowner looking at wall insulation is not really asking who installs it. They are asking whether they qualify for funding, and if not, what it costs to pay for it themselves. A site that treats those as the same visitor loses both. The funded visitor cannot find the criteria and leaves to check elsewhere; the self-funded visitor sees grant language everywhere, assumes they are not the customer, and leaves too. Splitting that path early is usually the single highest-impact change we make to a retrofit site.
The second is competence. Every serious buyer in this sector is checking whether you are accredited before they read anything else, whether that is a homeowner who has read one horror story about botched cavity wall, a scheme administrator checking a subcontractor or a commercial client running a procurement exercise. TrustMark, PAS 2035, PAS 2030, MCS: these are not decorations for the footer. Sites that surface them at the point of decision convert materially better than sites that bury them on an About page.
Structurally, the fix is almost always the same, and it is unglamorous. A page per measure, not a page per company. Cavity wall insulation, loft insulation, internal wall insulation, external wall insulation, underfloor, room-in-roof: each one is a distinct search, a distinct price point and a distinct set of objections. The same logic applies across the sector: air source and ground source heat pumps are different pages; domestic, workplace and destination EV charging are different pages. Firms that collapse all of it into one services page compete for one term and rank for none.
None of this is theoretical positioning. It is the same principle we apply to every website we build (the site should mirror how the buyer actually decides), applied to a sector where the decision has an unusual number of qualifying gates in front of it.
If your work sits more broadly across generation and supply rather than installation, our guides to web design for renewable energy companies and digital marketing for renewable energy companies cover that end of the market in more depth. For the search side of the same problem, our SEO service is where the measure-level page structure actually gets ranked.

Frequently asked questions
Do you specialise in insulation company websites?
Insulation and retrofit is the core of this service, yes. The structure we build for an insulation installer is a page per measure, an eligibility qualifier splitting funded from self-funded, accreditation surfaced at decision points, and lead routing by measure and region. That same structure works for heat pump engineers, solar installers and EV charge point operators, which is why they sit on one page here rather than four. If you install one measure only, the site gets simpler, not more generic.
How should a retrofit website handle grant funding and eligibility?
With a short qualifier early in the journey, and with separate routes after it. Funding schemes in this sector change, open, close and get replaced, so the important design decision is that the site does not hard-code one scheme into its architecture. Eligibility criteria live in one maintainable place, the qualifier reads from it, and self-funded visitors get a genuine route of their own rather than being treated as a failed grant enquiry. That way a scheme change is a content update, not a rebuild.
What pages does an insulation or retrofit company website actually need?
One page per measure you install and want more of, a project or case study library filterable by measure and region, an accreditation and compliance page covering TrustMark, PAS 2035 or 2030 and any scheme memberships, a clear eligibility or funding page, service-area pages if you cover multiple counties, a team page, and separate enquiry routes for funded work, self-funded work and commercial or social housing contracts. For most installers that is fifteen to twenty-five pages. Adding more only helps if each one answers a real search or a real objection.
Do you work with EV charging companies?
Yes, and the honest framing is that domestic, workplace and destination charging are three different businesses sharing a name. Domestic is a fast, price-sensitive consumer sale. Workplace involves a procurement process, grant paperwork and a facilities manager. Destination charging is a commercial partnership conversation. A single site can serve all three, but only if each has its own route through it. Where an operator only does one of the three, we build for that one properly.
How does accreditation affect the site structure?
More than most installers expect. TrustMark, PAS 2035, PAS 2030, MCS and competent-person scheme membership are qualifying criteria in this sector, not credibility garnish. They belong on measure pages, on quote forms and in structured data, not just in the footer. For commercial and social housing work the accreditation page is frequently the page a procurement lead reads before they read anything else, so it is worth building properly rather than as an afterthought.
We already have a website. Is this a rebuild or can you improve what we have?
Often it is neither a full rebuild nor a cosmetic refresh. If the underlying site is fast and maintainable, the work is usually structural: splitting a single services page into measure pages, adding the eligibility route, fixing accreditation placement and repairing tracking. That is a smaller job than a rebuild and it tends to move enquiries faster. We say which of the two you need at the audit stage, and we have told plenty of companies their site was not the problem.
How long before a new low-carbon website starts generating enquiries?
Paid search can generate enquiries in the first week if the seasonality justifies spending there. Organic is slower: expect three to six months for measure pages to gain meaningful visibility on a domain with some history, and longer on a brand new domain. If you are rebuilding rather than starting fresh, protecting existing URLs with proper redirects is the single biggest factor in how quickly rankings recover, and it is the step most rebuilds get wrong.
What does a website like this cost?
We quote per project rather than from a rate card, because the range in this sector is genuinely wide. A single-measure installer with six pages and a sole-trader team is a different job to a regional retrofit contractor with twelve measures, social housing contracts and an eligibility engine to maintain. The audit is free and it comes with a scope and a number, so you can see what the work involves before committing to anything.
