SEO & Organic Growth for Eco / Energy / Heating / Solar — The Practitioner’s Playbook.

SectionThe honest reframe most SEO agencies won't tell you

Generic SEO agencies sell eco-energy installers a "national SEO strategy" or a stack of cookie-cutter location pages — fifty postcode pages spun off one Services template, all targeting "renewable energy installer Bournemouth" or "solar company UK." Then they wonder why the site loses ground every time an ECO4 window opens or a Boiler Upgrade Scheme uplift is announced and a competitor's funded-grant cluster sprints past it.

Eco-energy is not "trades SEO with green branding." It is a sub-vertical, scheme-window, regulator-trust market. The buyer searching "ASHP grant BH8" is in a different intent slice from "solar PV finance options" or "ECO4 free insulation eligibility." Each sub-vertical has its own grant scheme, its own accreditation stack (MCS, RECC, TrustMark, NICEIC), its own seasonality, and its own decision criteria. Generic agencies do not structure for any of that — they ship volume content and hope for the best.

This playbook fixes the structure. The sub-vertical pillars are the engine. The postcode × technology programmatic set is the multiplier. The accreditation schema and review velocity are the moat. Read it, run it yourself, or have us ship it on retainer.

SectionThe eight-point audit we run on day one

Score your own GBP + site red / amber / green this week.

1. Sub-vertical pillar pages indexed and ranking — A separate, indexable, schema-marked pillar page for solar PV, ASHP, GSHP, EV charging, battery storage, retrofit insulation. Not one combined "Renewables" page. Each pillar should be ranking on its own head terms in Search Console; if Search Console shows one URL ranking for everything, you have a cannibalisation problem and a thin-content problem at the same time.
2. Postcode × technology programmatic page set — One indexable page per postcode area × technology you cover (e.g. /ashp-bh8/, /solar-pv-bh8/, /ev-charging-bh9/). Local schema, area-specific install gallery, area-specific testimonials, postcode-aware quote form. Most installers have zero of these and rely on a single Service Areas page.
3. MCS / RECC / TrustMark / NICEIC schema in JSON-LD — Accreditation numbers visible in Service.provider.identifier, organisation memberships in memberOf, footer trust strip with inline-SVG logos. Google reads JSON-LD; the buyer reads the footer. Both need to see it.
4. Install-photography schema with ImageObject — Real install photos with ImageObject schema including caption, creator, contentLocation, dateCreated. Tagged with the technology and the postcode area. Builds Google's confidence that you actually do the work in the area, not just sell into it.
5. LocalBusiness + Service + Review + AggregateRating schema — Four schemas live on every page. AggregateRating drives star-snippet eligibility in SERPs; Review schema preserves individual review structure; Service schema declares the sub-vertical you operate in; LocalBusiness anchors the local-pack signal.
6. Mobile Core Web Vitals on the quote page — LCP under 2.5s, INP under 200ms, CLS under 0.1 specifically on the quote-form page. Mobile is 70%+ of eco-energy traffic, and most installer quote forms fail at least one CWV on mobile. PageSpeed Insights field data is the source of truth, not lab scores.
7. Review velocity at 4–8 per month with named-installer responses — Steady review flow per month, not a one-time push. Owner or installer responses on at least 80% of reviews. Local-pack rewards recency and dialogue, not lifetime totals. A 4.9-star average from 240 reviews two years ago beats nothing, but a 4.7-star average with 6 fresh reviews per month and visible installer replies beats it for ranking.
8. Funded-grant calendar overlay on content cadence — A content plan that fires the cluster two to four weeks ahead of the BUS uplift, the ECO4 window, the GBIS announcement, the SEG tariff change. Not a flat "2 blogs a month." If your content calendar does not reference grant-scheme dates, you are publishing into the off-season.

Three or more reds — fix the foundation before any new content or paid spend.

SectionSix productised deliverables we ship per cycle

Sub-vertical pillar architecture. A separate, indexable pillar page per technology — solar PV, ASHP, GSHP, EV charging, battery storage, retrofit insulation. FAQ schema, install gallery, sub-vertical-specific quote form, internal links to the supporting blog cluster, dedicated metadata and Open Graph per page. The structural lever that lets you rank on each technology's head terms without cannibalising. Time to first signal: 30–60 days. Owned by you, exported as written SOP plus the page templates.

Postcode programmatic set. One indexable page per postcode area × technology you cover. Local schema, area-specific install examples, district-level testimonials, postcode-aware quote form pre-populated to the right scheme. One template ships 100–400 indexable pages from a roster of six technologies × twenty postcodes. Drives the "ASHP installer near me" long-tail without paying brand-bid premiums on Google Ads. Time to first signal: 45–75 days as Google indexes the new URL set.

Schema deployment + accreditation footer. LocalBusiness + Service + Review + AggregateRating + FAQ + ImageObject schemas on every page. MCS / RECC / TrustMark / NICEIC numbers in JSON-LD provider.identifier. Inline-SVG accreditation footer (no late-loaded images that drop CLS). Validates clean in Schema.org validator and Search Console's Rich Results test.

Funded-grant content cluster. A blog plus landing-page cluster firing two to four weeks before each scheme window — BUS uplift, ECO4 phase changes, GBIS announcements, Home Upgrade Grant rounds, SEG tariff updates. Each cluster pulls intent at the moment buyers start researching eligibility. Cluster pieces internal-link back to the relevant sub-vertical pillar and the funded-grant calculator, sharpening the conversion path.

Review velocity programme. SMS-based review request fired 24h after handover, named-installer responses, monthly review-velocity reporting. Target 4–8 reviews per month with 80%+ owner or installer response rate. Compounding effect on local-pack ranking and on quote-form conversion — buyers read recent reviews before they fill the form.

Mobile CWV tuning. LCP under 2.5s on the quote-form page. INP under 200ms on the form-fill journey. CLS under 0.1. Lighthouse CI runs in your build pipeline so future deploys cannot regress. Especially load-bearing for eco-energy where mobile traffic is 70%+ and the sales journey is 45–90 days from first click to install — every CWV regression compounds across that window.

SectionWhat to do this week

Three actions, ranked by leverage.

1. Count your sub-vertical pillar pages. Owner: founder. Time: 10 minutes. Open your site and count separate, indexable pages per technology. If solar PV, ASHP, GSHP, EV, battery and retrofit are crammed into one combined "Services" page, you are undershooting indexability by an order of magnitude — and Google cannot tell which page should rank for which sub-vertical query.
2. Run mobile Lighthouse on your quote-form page. Owner: marketing manager or developer. Time: 5 minutes. Note the LCP, INP, CLS scores from the field-data section of PageSpeed Insights, not the lab scores. If any is in the orange or red zone, this is your highest-leverage CWV fix and it is gating a 45–90 day sales journey for every visitor on mobile.
3. Decide DIY, DWY or DFY for the next 90 days. Owner: founder. See the three ways.

SectionFive questions eco-energy operators ask us about SEO

What's a realistic cost-per-survey from organic in this category? Cost-per-survey from organic settles between £80–£200 once the sub-vertical pillars and the postcode programmatic set are running, depending on technology mix and competition density. ASHP and GSHP run higher-cost, higher-margin (£150–£200 CPS, £600–£900 cost-per-install). Solar PV with strong scheme overlap can run lower (£80–£140 CPS, £400–£700 CPI). Most installers we talk to are paying £250–£400 per survey on paid before they fix the organic stack.

How long until we're in the local-pack top 3 for each sub-vertical? Time-to-signal for unsuppressed competitive postcodes is 60–90 days for the head sub-vertical (whichever you have the most reviews and install photos in). Secondary sub-verticals follow in 90–120 days as the pillar pages mature and the postcode set is indexed. ASHP and EV charging local packs are typically less competitive than solar PV in the same postcode — easier wins to land first.

GBP optimisation vs traditional on-site SEO — where should we focus? Both, but in sequence. GBP is the local-pack engine for "near me" intent (40–50% of eco-energy mobile search). On-site is the multiplier for sub-vertical research intent ("ASHP eligibility BUS scheme") which is where 45–90-day buyers begin. Foundation tier ships GBP completeness plus sub-vertical pillars in parallel. Compound runs the postcode programmatic set plus funded-grant clusters on top.

What's the single biggest local-pack lever in this category? Review velocity with named-installer responses, by some distance — provided your GBP primary category is correct (Solar Energy Company / Heating Contractor / EV Charging Station Contractor as appropriate). 4–8 reviews per month with 80%+ installer-named responses beats nearly every other signal. Most installers chase backlinks while their review tap is dripping and their categories are mis-set.

Can we run this ourselves with the playbook + £750 audit? Yes. The full sub-vertical pillar + postcode programmatic + schema + funded-grant cluster + review velocity stack is achievable in-house with a marketing manager and one developer half-week per cycle. The £750 audit gives you a written red/amber/green of all eight points, a prioritised next-step list with named owners and dates, and a copy of the page templates and schema blocks. Credit toward first cycle if you sign for DWY/DFY within 30 days.
