Short answer: Solar is a high-value, research-heavy purchase where MCS certification is effectively a prerequisite for serious enquiries. UK installers win locally by making certification unmissable, publishing genuine performance and payback data, and covering battery storage as a distinct service rather than an afterthought.
Solar buyers research harder than almost any local customer
A homeowner considering solar will typically spend weeks reading before contacting anyone. They will look into payback periods, export tariffs, panel efficiency, inverter brands, roof orientation and warranty terms.
This is unusual. Most local services are chosen quickly on trust and proximity. Solar is chosen slowly on evidence — which means content genuinely matters here in a way it does not for, say, emergency plumbing.
MCS certification is non-negotiable
MCS certification is required for customers to access export payments through the Smart Export Guarantee. Without it, you are excluded from most serious residential enquiries — informed buyers filter on it early.
Make it prominent:
- State it in your Google Business Profile description
- Include your MCS number on your website
- Mention RECC or HIES consumer code membership alongside it
- Reference it in Google Posts about completed installs
Do not put it in your business name — that breaches Google guidelines regardless of how legitimate the credential is.
Battery storage is its own search intent
Battery storage demand has grown substantially, driven by rising electricity costs and time-of-use tariffs. Crucially, it splits into two distinct audiences:
| New solar + battery | Battery retrofit | |
|---|---|---|
| Customer | No existing system | Already has panels |
| Search intent | solar panels and battery cost | add battery to existing solar |
| Competition | High | Noticeably lower |
| Sales cycle | Long | Shorter — already convinced on solar |
Retrofit is the under-served side. Homeowners who installed panels years ago and now want storage are a warm, motivated audience with far fewer companies competing for their attention. If you do retrofits, give it a dedicated service listing and its own website page.
Publish real numbers
Solar buyers are trying to answer one question: will this pay for itself, and when? Vague marketing language fails against that. Specific, honest figures succeed.
What works:
- Case studies with actual system sizes, actual generation figures and actual bill impact
- Realistic payback ranges, with the assumptions stated
- Honest discussion of what reduces performance — north-facing roofs, shading, older properties
Being candid about when solar is not a good investment is counter-intuitively one of the strongest trust builders in this sector, because the industry has a reputation for overselling. It also filters out enquiries that would waste your survey time.
Category setup
Primary: Solar energy contractor or Solar panel installation service depending on availability.
Secondaries: electrician (if you hold the qualifications), roofing contractor (if you handle roof work in-house), energy equipment and solutions.
Reviews that carry weight in solar
Solar reviews are most persuasive when they reference outcomes over time — “eighteen months in and our bills are down roughly what they projected” is worth more than “tidy install, nice lads”.
That means going back to customers some months after installation, not just at handover. A follow-up at six or twelve months serves two purposes: it produces genuinely valuable reviews, and it is a natural moment to discuss battery retrofit.
Commercial solar is a separate business
If you install commercial systems, treat it as a distinct offering. Commercial buyers search differently, evaluate on ROI models and payback schedules, want references from comparable sites, and often run procurement processes.
A single page that lumps commercial in with domestic will convert neither well.
Frequently asked questions
Do I need MCS certification to rank?
Not to rank, but effectively yes to convert. Informed customers filter for it, and without it they cannot access export payments.
What is the most valuable solar keyword?
Battery retrofit terms often offer the best ratio of intent to competition — the customer is already sold on solar and is looking for a specific upgrade.
How long is the solar sales cycle?
Commonly several weeks to a few months from first research to signed order. Local search visibility needs to be sustained across that window, not switched on at the point of decision.
Should I publish prices?
Indicative ranges by system size help serious buyers self-qualify and reduce wasted surveys. Vague “contact us for pricing” underperforms in a sector where buyers are actively comparing.
