UK solar demand just hit its highest point in over a decade, and most installers still aren't set up to capture the enquiries flooding in. The gap between demand and capture is where the money's being left on the table — and a demand-led lead marketplace like Referr is exactly how you close it Solar Panel Installation Lead Requests.
UK Solar Demand Is at a Decade High
2025 has been the strongest year for UK solar on record, full stop. MCS certification data shows 257,397 installations registered in 2025 alone — a 32% year-on-year jump — taking deployed capacity to 21.6 GW. Zoom out further and the shift is even starker: UK solar capacity now sits at roughly 18 GW, up from under 5 GW a decade ago, according to IBISWorld.
The output side tells the same story. The UK generated 14.43 billion kWh of solar electricity in 2025, enough to power over 5 million homes, per GreenMatch. Cumulative installations now stand at 1.73 million, a 6.8% rise year-on-year, and renewables overall now supply 37% of UK electricity — overtaking fossil fuels for the first time. Falling equipment costs are driving all of it: solar panel costs have dropped roughly 90% globally.
This isn't a blip you can file away as background noise. It's a sustained demand curve, and installers need a way to buy against it that scales with the market rather than lagging behind it. That's precisely the gap Referr's demand-led marketplace is built to fill: instead of chasing generic enquiries, installers set their own price, choose their region, and pull in leads as demand rises pay on completion leads how to buy leads as a UK tradesperson, without waiting on a long-term contract to catch up.
Speed-to-Lead: The Real Reason Installers Lose Jobs
Here's the uncomfortable bit: most installers aren't losing jobs because demand is soft. They're losing jobs they should have won, because someone else called the customer back first.
Solar buyers behave like every other high-value home improvement buyer — they ask three or four installers for a quote the same day, and go with whoever turns up fastest and feels most credible. Leave an enquiry sitting in an inbox for six hours while you're up a ladder, and a competitor's already booked the survey.
This matters even more with purchased leads than organic ones — a lead is often being chased by more than one installer the moment it lands, especially where it's been shared rather than exclusive. That's exactly why exclusivity matters so much when you're choosing where to buy from speed-to-lead matters so much when you're choosing where to buy from. On Referr, leads are matched to the installer who purchases them rather than blasted to five competitors at once, which means you're racing the clock, not racing four other quotes for the same job.
The installers seeing the best returns still treat every lead like it has a 15-minute shelf life. That means a mobile-first way of catching enquiries the moment they land — Referr's dashboard notifies you instantly when a lead in your area matches your criteria — a scripted first-call opener that doesn't sound like a script, and someone whose actual job is to pick up fast. Unglamorous, yes. But it moves conversion rates more than almost any other single change you can make.
Regional Hotspots: Where to Focus Your Lead Spend
Not all of the UK is heating up equally, and buying leads without a regional strategy wastes money in areas where demand is flat — or where you're one of hundreds of installers competing for the same postcode.
MCS's 2025 local authority data puts Somerset (3,741 certified installations) and Cornwall (3,726) at the top of the table, with North Yorkshire (2,780), County Durham (2,668) and Wiltshire (2,545) rounding out the top five. But volume alone doesn't tell the full competitive picture. Solarinfo.uk's installer density data shows London has 185 installers for over 9 million people — 49,134 people per installer — while the South West has 567 installers for under 6 million people, working out at just 10,387 people per installer. Wales sits similarly at 10,054 people per installer.
The takeaway: high demand doesn't automatically mean high opportunity if a region's already saturated with installers. This is where a marketplace model earns its keep — rather than committing to a fixed regional contract, Referr lets you buy leads by postcode and region on your own terms, so you can lean into under-served pockets like North Yorkshire or County Durham one month and pull back if a market gets crowded, without renegotiating anything.
The South West carries a second advantage worth building a strategy around: it has one of the highest concentrations of older, Feed-in-Tariff-era solar installs in the country. That installed base isn't just history — it's your next lead category.
The Battery Storage Retrofit Opportunity
Battery attachment is the upsell most installers are sitting on without realising it. The FiT scheme ran from 2010 to 2019, meaning there are hundreds of thousands of UK homes with solar panels installed on ageing inverters, no battery storage, and export tariffs that no longer reflect what's available today.
Flexible export tariffs like Octopus Outgoing and Agile Export have changed the maths on batteries considerably — a household exporting at a flat rate under an old FiT contract can often do meaningfully better by adding storage and switching to a tariff that rewards flexible use. That's a compelling, honest pitch, and existing solar customers are far more receptive to it than a cold roof-based enquiry.
The lead-buying implication is straightforward: don't only buy leads for net-new solar installs. Because Referr operates as a marketplace rather than a single fixed-catalogue provider, sellers can list and tag leads specifically for battery retrofits, inverter replacements, or FiT-era households — a segment almost nobody targets deliberately yet. That means less competition per lead and higher trust from a homeowner who already believes in solar.
How do I find FiT-era solar homes to target?
Look for properties with visible older-generation panel styles, cross-reference postcodes against known FiT installation waves (2010–2015 saw the highest volumes), and ask your existing customer base for referrals — most FiT-era owners know several solar neighbours from the same period. You can also filter for these households when sourcing leads through a marketplace like Referr.
New-Build Solar: A Distinct Lead Category
New-build properties now account for 35% of all UK solar installations, according to Solar Weekly — and that share's climbing as building regulations push developers toward fabric-first, low-carbon specs as standard.
This customer looks nothing like the retrofit homeowner. They're not weighing up whether to have solar — the developer's already made that call for them. Your opportunity sits in upgrades and add-ons: bigger battery capacity than the developer specified, EV charger integration, or optimising an under-sized system. The sales conversation is shorter and needs far less persuading, but it demands different positioning — you're competing on technical credibility and speed of installation, not on convincing someone solar's worth doing at all.
As this segment grows, lumping it into one undifferentiated lead pool is a mistake. Whether you're buying from a marketplace or generating your own, tag new-build enquiries separately from retrofit ones. Referr's category-and-region filtering makes this easy to manage from a buyer's side — set separate criteria and pricing for new-build enquiries versus retrofit ones, rather than paying the same rate for two very different sales conversations. Treat a pre-sold new-build customer with the same script and follow-up cadence as a sceptical bungalow owner, and you'll waste the advantage they've handed you.
Google Ads vs SEO vs Buying Leads: Real Cost-Per-Lead Numbers
Every installer eventually asks the same question: where should the next £1,000 of marketing budget go? The honest answer depends on how fast you need results, and how much cash you're happy to tie up before it pays back.
Google Ads for solar keywords in the UK typically runs £80–£250 per lead, converting at 10–15%, according to Solar Weekly's cost analysis. Fast, sure — you could be fielding enquiries within days — but pricey, and quality swings wildly depending on how tightly you've built your negative keywords and geo-targeting.
Organic SEO converts far better, at 25–30%, with next-to-no marginal cost once you're ranking. The catch's time. Building genuine organic visibility for competitive solar terms takes months, sometimes over a year — a poor fit if you need jobs in the pipeline this quarter.
Buying leads through a marketplace sits neatly between the two, typically from around £25 per lead for higher-intent, fully qualified enquiries — a fraction of Google Ads cost, without SEO's year-long wait. On Referr specifically, sellers set the price, so competitive markets settle at fair rates naturally rather than being locked to a fixed agency rate card.
This is where The Three-Layer Lead Stack approach earns its keep: run SEO as your long-term, low-cost foundation; use Google Ads sparingly for a quick top-up when the pipeline's dry; and use a marketplace like Referr as your flexible middle layer to scale fast during demand spikes — like the one we're in now — without the CPL punishment that comes with paid search, and without a contract locking you in once the spike passes.
How to Vet a Solar Lead Marketplace
Cheap shared leads look great on a spreadsheet and perform badly in the real world. If a £10 lead is being pitched to five other installers at once, your true cost-per-conversion often ends up higher than a £25 exclusive lead that lands with you alone — because now you're racing on speed and price against rivals who saw the same enquiry seconds after you did.
Before paying anyone for leads, run a proper check. Call it the 4-Point Vet-Before-You-Buy Checklist:
Exclusivity terms — ask explicitly how many installers receive each lead, and get it in writing.
Replacement or refund policy — a credible seller will replace or refund a lead that's a wrong number, a duplicate, or clearly outside your service area. Referr's money-back guarantee is built around exactly this problem.
Verification method — how is the enquiry confirmed as genuine (phone verification, form validation, IP checks)?
Payment security — Referr processes every transaction through Stripe, so there's no chasing invoices or wiring money to an unverified seller.
Generic lead marketplaces built for every trade under the sun tend to miss the nuance solar buying and selling demands — the difference between a retrofit lead and a new-build one, or a FiT-era battery prospect and a cold roof enquiry. A niche-aware marketplace where multiple sellers compete for your business, and where you can filter by category, region, and exclusivity, gives you leverage a single fixed-price agency contract never will.
Frequently Asked Questions
Does solar demand in the UK change with the seasons?
Yes — enquiry volume typically peaks from spring through late summer as homeowners see their energy usage and bills more directly, then dips over winter. Installers buying leads through a marketplace like Referr can weight spend toward Q2 and Q3, while using quieter winter months for battery retrofit and inverter-replacement campaigns aimed at existing solar customers.
Should I negotiate lead prices during a demand spike?
Where possible, set your buying criteria and budget before a spike fully plays out rather than after, since demand-driven pricing on any marketplace tends to firm up once enquiries visibly outstrip supply. Because Referr lets buyers set their own price thresholds, you can lock in a comfortable rate during a calmer period and adjust as the market moves.
Is MCS certification actually a selling point with customers?
Yes. MCS is the recognised UK standards body for solar and battery installations, and homeowners increasingly check for it before committing, particularly given eligibility rules tied to schemes like the Smart Export Guarantee. Displaying MCS certification prominently when following up on a purchased lead measurably improves trust and conversion.
How quickly should I respond to a purchased solar lead?
Aim to make contact within 5 minutes where possible, and certainly inside the first hour. Shared leads especially are often being contacted by multiple installers simultaneously, so response speed is frequently the deciding factor in who gets the job — one more reason exclusive leads from a marketplace like Referr tend to convert better than shared ones.
Are battery storage leads worth buying separately from solar leads?
Yes, particularly if you can target existing solar households rather than net-new customers. This audience already believes in the technology, often has an ageing inverter or a poor legacy export tariff, and converts faster than a cold solar enquiry. Most generic lead sellers don't segment for this yet, which is exactly why sourcing it through a marketplace where category tagging is granular — like Referr — is worth setting up now.
Demand for UK solar and battery installs isn't easing off any time soon, but the installers who profit from it will be the ones treating lead generation as deliberately as their installation work — matching lead type to region, buyer profile and follow-up speed, rather than buying generic leads and hoping. Referr's demand-led marketplace gives you the control to do exactly that: choose your region, set your price, and buy exclusive, verified leads as the market moves. Get your response time and lead sourcing right now, while the market's still moving fast.
