The UK solar market is growing at pace - net zero targets, rising energy prices and growing consumer awareness mean more households and businesses are enquiring about solar than ever. But more enquiries only become more installations if your sales operation can handle the volume, and most UK installers are running sales on tools that were never built for solar.
This guide ranks the CRMs and sales tools UK solar installers actually shortlist in 2026, what each is best at, and where each falls short for solar.
What to look for in a solar CRM
A solar CRM has to run the whole journey - from first website click to a signed contract and completed install. The things that matter:
- Self-qualifying lead capture - a structured enquiry flow, not a basic contact form
- Solar-specific pipeline - enquiry, survey, quote, contract, install
- Instant proposal generation - professional quotes from your own equipment and pricing in minutes
- Marketing source tracking - which channel produced each signed job, not just clicks
- MCS-ready professionalism - clean enquiry flows and branded proposals that reflect your certification
- Fast setup - live in days, not weeks of configuration
The best solar CRMs for UK installers, ranked
| # | Tool | Best for | Built for solar? | Lead capture + qualify | Proposals | MCS-ready |
|---|---|---|---|---|---|---|
| 1 | Voltflo | The full solar sales journey | Yes | Dynamic flow, auto-qualifies | Built in, minutes | Yes |
| 2 | HubSpot | Marketing-led teams | No | Build it yourself | Add-on tool | Manual |
| 3 | Zoho | Flexible, budget-conscious | No | Heavy configuration | Not built in | Manual |
| 4 | Pipedrive | A simple deal pipeline | No | None | None | No |
| 5 | Monday | Task/project tracking | No | None | None | No |
| 6 | OpenSolar | Free system design | Design only | No | Design proposals only | N/A |
1. Voltflo - best overall for solar installers
Best for: installers who want capture, qualify, quote, track and measure in one system built for solar.
Strengths: Voltflo runs UK solar sales end to end out of the box. A dynamic enquiry flow captures and qualifies every website lead; proposals generate in minutes from your own equipment catalogue; a solar-specific pipeline (enquiry to signed job) keeps everything moving; and marketing source tracking shows which channels drive real revenue. The enquiry flows and branded proposals reflect the professionalism MCS certification demands, and you're live in about 48 hours. It integrates with HubSpot, Zoho, GoHighLevel and Monday if you want to keep part of your stack.
Watch-outs: it's a sales and operations platform, not a technical panel-layout tool - pair it with OpenSolar for detailed design if needed.

2. HubSpot - best for marketing-led teams
Best for: installers with a marketing person and budget for the higher tiers.
Strengths: a polished general-purpose CRM with excellent marketing automation. Where it falls short for solar: no solar enquiry flow, no built-in proposal generator, no MCS or UK-market context - you build it yourself or add third-party tools. Many UK installers run Voltflo alongside HubSpot for the solar layer.
3. Zoho - best flexible, budget-conscious option
Best for: teams that want a broad, affordable suite and time to configure it.
Strengths: flexible and low cost. Where it falls short for solar: most installers end up with a half-built system the team never fully adopts, with no solar proposals or MCS-ready flows out of the box.
4. Pipedrive - best simple deal pipeline
Best for: a small team that just wants to track deals.
Strengths: clean and quick to learn. Where it falls short for solar: no lead capture flow, no proposal generator, no attribution - most installers outgrow it fast.
5. Monday - best for task and project tracking
Best for: managing installs and internal tasks.
Strengths: great flexible project boards. Where it falls short for solar: it's a project tool stretched into a CRM - no lead capture, proposals or marketing attribution, so it ends up beside spreadsheets and separate quoting tools.
6. OpenSolar - best free system design
Best for: the design and technical proposal step.
Strengths: a strong, free solar design tool. Where it falls short: it doesn't capture and qualify website leads, run a sales pipeline, or track revenue by channel - run it alongside a CRM, not instead of one. See Voltflo vs OpenSolar.

What UK installers specifically need
MCS-certified professionalism
If you're MCS-certified, trust is your edge. Your CRM should reflect that - professional enquiry flows, branded proposals, and a pipeline that matches how UK solar sales actually progress.
Quote-to-install pipeline
UK solar sales run enquiry, survey, quote, contract, install. Your pipeline stages should match that - not a generic "lead, opportunity, closed" built for software sales.
Marketing source tracking
You're likely running Google Ads, Facebook and local marketing at once. Without source-to-revenue tracking you're budgeting on guesswork - a proper solar CRM follows every enquiry through to the signed job.
Proof: JR Energy
JR Energy implemented Voltflo and tripled installations from the same website traffic, saved 12+ hours a week on admin, and now only has sales conversations with qualified, engaged prospects - no extra leads bought, no extra ad spend. Read the full case study.
The verdict
If you only need system design, OpenSolar does that well. If you have a marketing team and budget to build your own solar layer, HubSpot can work. But if you want one system that captures, qualifies, quotes and tracks every solar job - MCS-ready and live in days, not weeks - Voltflo is the CRM built for the job.
