Solar Installer Marketing Guide UK 2026: How to Get More Customers
The most effective marketing strategies for UK solar installers in 2026. Google Business Profile, comparison sites, reviews, local SEO, paid ads vs leads, referrals, and common mistakes to avoid.
The UK solar market is booming. Over 1.5 million homes already have solar panels, the government has committed to tripling solar capacity by 2030, and demand from homeowners continues to climb. For MCS-certified installers, the opportunity has never been bigger.
But opportunity means competition. There are thousands of solar installers in the UK, and the ones growing fastest are not necessarily the best at fitting panels — they are the best at getting found by the right customers. This guide covers the most effective marketing strategies for solar installers in 2026, from free tactics to paid options, with real numbers on what actually works.
1. Optimise Your Google Business Profile
This is the single highest-ROI marketing activity for any local solar installer, and it is completely free. When a homeowner searches "solar panel installer near me" or "solar panels [town]", Google shows the Maps pack — three local businesses with reviews, photos, and contact details. If you are not in that pack, you are invisible to your most valuable potential customers.
How to optimise it
- Correct your primary category to "Solar Energy Contractor" or "Solar Energy Company"
- Add all service areas — every town and county you cover
- Upload real photos of your installations. At least 10-15 photos of completed jobs, your team, your vehicles. Google rewards profiles with more photos
- Post weekly updates — finished installs, before/after shots, seasonal tips. Google Business posts keep your profile active and improve visibility
- Respond to every review within 24-48 hours, positive or negative. This signals to Google that you are an active, engaged business
- Add your MCS certification number to your business description
- Keep your opening hours accurate — incorrect hours frustrate potential customers and hurt your ranking
A well-optimised Google Business Profile can generate 5-20 enquiries per month for free. Most installers barely touch theirs, so even basic optimisation puts you ahead.
2. Get Listed on Solar Comparison Sites
Comparison sites like Solar Info rank highly in Google for searches like "solar panel installers in [county]" and "compare solar companies". Homeowners visiting these sites are actively researching solar — they are much further along the buying journey than someone scrolling Facebook.
The key advantage of comparison site leads over self-generated leads is intent. Someone searching Google for "solar panel quotes" is ready to buy. Someone who clicks a Facebook ad for "free solar quote" may have been curious but was not actively shopping.
What to look for in a comparison site
- Organic traffic — the site should rank in Google, not just buy traffic from ads
- Lead sharing — how many installers receive each lead? Fewer is better. Look for 3-4 maximum
- Lead validation — are phone numbers verified? Is there a real quote form, or just a name and email?
- Your own profile — can homeowners see your company, reviews, and credentials before you call them?
- No long-term contracts — you should be able to pause or cancel if it is not working
Solar Info delivers verified homeowner enquiries from organic Google search traffic, shared with a maximum of 4 MCS-certified installers in the homeowner's area. Listings start from £49/month with no long-term contracts.
3. Build Your Reviews and Reputation
Reviews are the most powerful trust signal in the solar industry. A homeowner spending £6,000-10,000 on solar panels will check your reviews before picking up the phone. The difference between a 4.2-star and a 4.8-star Google rating can be the difference between getting the job and losing it to a competitor.
The "ask at handover" strategy
The best time to ask for a review is at system handover — when the customer is seeing their new panels generating electricity for the first time. They are excited, grateful, and most willing to leave a positive review. Have a simple process:
- Show the customer the monitoring app and their first generation reading
- Hand over the MCS certificate and warranty documents
- Ask: "Would you mind leaving us a quick Google review? It really helps other homeowners find us"
- Send a follow-up text or email with a direct link to your Google review page within 24 hours
Aim for a review from at least 50% of your customers. If you install 5 systems a month, that is 2-3 new reviews monthly — 30+ per year. Within a year, you will have more reviews than most competitors.
Trustpilot and other platforms
Google reviews matter most for local search rankings, but a Trustpilot profile adds credibility — especially if you are listed on comparison sites that aggregate Trustpilot scores. Some homeowners check Trustpilot by default for any company they are considering.
4. Local SEO: Rank for Your Towns
Beyond your Google Business Profile, your website should rank organically for local searches. The goal is to appear for terms like "solar panels [town]", "solar installers [county]", and "MCS solar installer near [postcode area]".
Key local SEO actions
- Create location pages on your website for each major town or county you serve. Include the town name in the title, mention local landmarks or conditions, and include a clear call to action
- NAP consistency — your business Name, Address, and Phone number must be identical everywhere: website, Google Business Profile, Yell, Checkatrade, Facebook, LinkedIn
- Local citations — get listed on Yell.com, FreeIndex, Thomson Local, Bark, Checkatrade, and any local business directories. Each listing with consistent NAP information strengthens your local ranking
- Case studies — write up 2-3 real installations in your area with photos, system specs, and customer quotes. These provide unique local content that Google values
5. Your Website: the Basics Most Installers Miss
Most solar installer websites are surprisingly poor — stock photos, no clear pricing, slow loading, not mobile-friendly. The bar is low, which means even basic improvements can make a significant difference.
What a good installer website needs
- MCS certification badge prominently displayed — this is the trust signal homeowners look for
- Real installation photos — not stock images. Before/after shots of actual jobs you have completed
- Clear service areas — list the counties and towns you cover
- A quote request form on every page, not just a "contact us" page buried in the footer
- Mobile-friendly design — over 60% of homeowner searches happen on phones
- Page speed — if your site takes more than 3 seconds to load, you lose visitors. Use Google's PageSpeed Insights to check
- Customer testimonials with full names and locations (with permission)
- Pricing guidance — even a rough range helps. Homeowners want to know if they can afford it before they call
6. Paid Ads vs Buying Leads: The Maths
Some installers run their own Google Ads. Others buy leads from comparison sites or lead generators. Here is how the numbers typically compare:
| Channel | Cost Per Lead | Conversion to Survey | Effective Cost Per Survey |
|---|---|---|---|
| Google Ads (self-managed) | £80–£250 | 20–30% | £270–£1,250 |
| Google Ads (agency-managed) | £60–£150 + agency fee | 25–35% | £200–£600 |
| Comparison site leads (shared) | £20–£50 | 25–33% | £60–£200 |
| Exclusive leads | £50–£150 | 30–40% | £125–£500 |
| Facebook Ads | £15–£40 | 10–15% | £100–£400 |
| Referrals | £50–£100 (referral fee) | 50–70% | £70–£200 |
The numbers show that referrals and comparison site leads typically offer the best cost per survey booked. Self-managed Google Ads are the most expensive unless you are experienced with PPC — the average small business wastes 40-60% of their ad spend on irrelevant clicks.
For most installers, the best approach is a combination: comparison site leads for consistent volume, Google Business Profile for free local visibility, and a referral programme for the highest quality leads.
7. Social Media: Brand Building, Not Lead Generation
Social media is not where solar leads come from — but it is where homeowners go to check if you are legitimate. Think of it as your shop window, not your sales team.
What works
- Before/after installation photos on Facebook and Instagram — these consistently get the highest engagement
- Time-lapse installation videos — even a simple phone video of a day's install sped up to 30 seconds performs well
- Customer testimonial posts — a photo of the happy homeowner with their new panels (with permission)
- Educational content — quick tips about solar savings, SEG rates, battery storage. Positions you as an expert
What doesn't work
- Posting generic stock images or manufacturer content
- Expecting direct leads from organic social posts — the conversion rate is extremely low
- Spreading yourself across every platform. Pick Facebook and one other (Instagram or TikTok) and do them well
8. Start a Referral Programme
Referrals convert better than any other lead source because trust is already established. A homeowner referred by their neighbour is 3-5x more likely to book a survey than a cold lead.
A simple referral programme structure:
- £50-£100 per referral that converts to a sale. Some installers offer £50 cash, others offer a £100 credit towards a battery or maintenance
- Tell every customer about the referral programme at handover — include it on a card with the warranty documents
- Follow up at 3 months — "How are your panels performing? By the way, if any neighbours are interested, here's our referral offer"
- Make it easy — a simple form on your website or even just "tell them to mention your name when they call"
Even a modest referral programme generating 2-3 leads per month at a 50-70% conversion rate is worth more than most paid advertising.
9. Mistakes to Avoid
We see the same mistakes from solar installers repeatedly. Save yourself the time and money:
- Buying cheap Facebook-scraped leads — these are people who clicked an ad out of curiosity, not people actively shopping for solar. Contact rates are low, conversion rates are worse
- Paying for directory listings that do not deliver — before signing up with any directory or lead provider, ask how many leads their existing solar installers in your area receive per month. Get a number, not a promise
- Neglecting your existing customer base — past customers are your best source of referrals, reviews, and repeat business (battery upgrades, maintenance contracts, EV charger installs)
- No follow-up process — speed to call matters enormously. Installers who call a lead within 5 minutes are 10x more likely to make contact than those who wait an hour. Have a system, not just good intentions
- Trying to do everything at once — focus on Google Business Profile + one lead source + referrals first. Add more channels once those are working
Where to Start
If you are an MCS-certified solar installer looking to grow, here is the priority order:
- Week 1: Optimise your Google Business Profile — correct category, add photos, update service areas
- Week 2: Set up a review collection process — aim for a review from your next 5 customers
- Week 3: Get listed on Solar Info and 2-3 other comparison sites to start receiving leads
- Week 4: Launch a simple referral programme — tell every past and future customer
- Month 2+: Improve your website, add local pages, consider paid ads if budget allows
The installers growing fastest in 2026 are not the ones with the biggest marketing budgets. They are the ones with the best MCS-certified reputations, the most reviews, and the smartest mix of lead sources. Start with the free and low-cost tactics above, measure what works, and scale from there.
