Best Quoting App for Solar Panel Installers in the UK 2026: Top 5 Compared
Solar panel installation is one of the most technically complex trades in the UK right now. A typical residential job involves a roof survey, a panel and inverter quote, a battery storage add-on option, DNO application paperwork, MCS certification records, and — increasingly — an EV charger alongside. When a customer asks for a price, they expect an itemised document that covers all of that clearly and professionally. Generic invoicing tools like Word templates or basic accounting apps simply were not built for this workflow, and it shows. Quotes get lost, jobs get underpriced, and MCS documentation becomes a last-minute scramble.
The good news is that purpose-built quoting apps have improved dramatically in the past two years. Several platforms now support UK VAT schemes, Construction Industry Scheme (CIS) deductions, and the kind of multi-line itemisation that a solar panel installation quote demands — covering panels, inverter, mounting hardware, battery storage, and labour separately. Choosing the right one can save a busy installer an hour or more per quote while also producing documents that look credible enough to win more work.
This guide compares the five best quoting apps available to UK solar panel installers in 2026. We cover pricing, UK-specific compliance features, mobile usability, and the practical pros and cons of each platform for a trade where the Smart Export Guarantee and MCS accreditation are non-negotiable considerations.
What Solar Panel Installers Need in Quoting App Software
Not every quoting app is suited to the solar trade. Before comparing platforms, it is worth being clear about what a UK solar panel installer actually needs from this kind of software:
- MCS certification documentation support. MCS-accredited installers must issue certificates for every completed installation. A good quoting app should at minimum make it easy to reference MCS certificate numbers on invoices and completion documents, and ideally store job records that satisfy MCS audit requirements.
- Detailed solar panel installation quote line items. A credible solar quote breaks out panels, inverter model and cost, mounting system, cabling, labour, scaffolding, and any optional battery storage or EV charger add-ons as separate lines. Apps that only support a single description field are not fit for purpose here.
- Battery storage quote options. The majority of residential customers now ask about battery storage at point of sale. The software needs to support optional add-on lines or alternative quote versions so installers can present a base solar quote and an upsell scenario cleanly on the same document.
- Smart Export Guarantee and DNO context. While an app cannot file a DNO application for you, it should at minimum allow notes and document attachments so that DNO application reference numbers, SEG tariff details, and grid connection information stay associated with the job record.
- UK VAT and CIS compliance. Solar installation falls under the 0% VAT rate for residential properties, but commercial jobs or battery-only installs may attract standard rate. The app must handle mixed VAT rates correctly and support CIS deductions for subcontractor payments.
- Roof survey cost tracking. Many installers charge a separate roof survey fee, sometimes refundable on job completion. The quoting app should make it easy to issue a survey invoice, then credit it or carry it forward when the full installation quote is accepted.
- EV charger add-on pricing. Bundling an OZEV-approved EV charger with a solar installation is increasingly common. The software should support product/service libraries so installers can quickly add EV charger line items from a saved price list rather than typing them from scratch each time.

| App | Free Plan | Paid From | Best For | UK Support |
|---|---|---|---|---|
| Sleepless Tradesman | Yes — free tier | £0/month | Sole-trader solar installers | Built for UK |
| Tradify | 14-day trial only | £29/user/month | Small solar teams | UK-focused |

1. Sleepless Tradesman — Best Free Option for UK Solar Panel Installers
Sleepless Tradesman was built from the ground up for UK tradespeople, and solar panel installers are among its strongest use cases. The platform uses AI to help generate quote line items quickly — useful when you need to list panels, inverter, battery, mounting hardware, and labour without starting from a blank page every time. The free tier has no monthly subscription fee, which makes it genuinely accessible for a sole-trader installer who is still building their customer base.
UK VAT is handled correctly, including the 0% rate applicable to residential solar installations under the Energy Saving Materials relief. CIS deductions are supported for subcontractor payments. You can attach documents to jobs, making it practical to store DNO application references, MCS certificate numbers, and roof survey notes against the relevant job record.
Pros for solar panel installers: No monthly cost on free tier; AI-assisted quoting speeds up itemised solar panel installation quotes; UK VAT/CIS built in; mobile-friendly for on-site use; job notes and attachments keep MCS and DNO paperwork organised.
Cons: Less feature-rich than paid platforms for scheduling large teams; no native GPS dispatch for managing multiple installation crews simultaneously.
2. Tradify — Best Paid Option for UK Tradespeople
Tradify is one of the most popular job management platforms among UK tradespeople, and at £29 per user per month it sits at a reasonable price point for a solar installer with one or two employees. It covers quoting, job scheduling, timesheets, and invoicing in a single interface. The platform is genuinely UK-focused — it supports VAT returns and integrates with Xero and QuickBooks for accounting.
For solar panel installers, Tradify's quote templates can be customised to include standard line items for panels, inverters, battery storage quotes, and EV charger add-ons, saving time on repeat jobs. The mobile app works well on site, and technicians can update job status from their phones while the office sees progress in real time.
Pros for solar panel installers: Strong UK market focus; customisable quote templates suit complex solar jobs; good scheduling for teams; Xero/QuickBooks integration; responsive customer support in UK time zones.
Cons: No free tier — costs add up quickly for small sole-trader operations; quote templates require manual setup initially; no AI-assisted line item generation.
3. ServiceM8 — Best for Field Service Dispatch
ServiceM8 originated in Australia and remains strongest for iOS-based field service workflows. It offers GPS dispatch, staff location tracking, and a clean mobile interface that works well for solar installation businesses running multiple vans and crews. Quotes, job cards, and invoices are all handled within the app, and it connects to Xero for accounting.
For UK solar panel installers, ServiceM8 is a reasonable choice if your main pain point is coordinating multiple installation teams across different sites. The dispatch board gives a real-time view of who is where and what stage each job has reached. However, UK-specific compliance features — particularly CIS deductions and the 0% VAT rate for residential solar — require more manual configuration than platforms built for the UK market from the start.
Pros for solar panel installers: Excellent GPS dispatch and crew tracking; strong iOS mobile experience; good for businesses running multiple installation teams; integrates with Xero.
Cons: Australian-origin platform means UK VAT and CIS require more manual setup; less intuitive for sole traders; Android experience lags behind iOS; pricing can escalate with add-ons.
4. Jobber — Best for Client Communication
Jobber stands out for its polished client-facing experience. Customers receive professional quote emails with an online approval portal, automated follow-up reminders, and a client hub where they can view job history and invoices. For solar panel installers who want to position themselves as premium installers — particularly in the domestic retrofit market — Jobber's client communication tools help build trust with homeowners making a significant investment.
The platform starts at around £49 per month and is primarily designed for the North American market, which means some UK-specific features require workarounds. CIS is not natively supported, and VAT configuration for the zero-rated residential solar scenario needs careful manual setup. That said, Jobber's quote builder is flexible enough to handle multi-line solar panel installation quotes, battery storage options, and EV charger add-ons clearly.
Pros for solar panel installers: Best-in-class client portal and quote approval workflow; automated follow-up sequences reduce quote chasing; clean, professional quote documents that reassure homeowners; good mobile app.
Cons: US-focused — CIS not supported natively; VAT rates need manual configuration; starts at £49/month which is steep for sole traders; customer support is US time zone.
5. QuickBooks — Best for Accounting Integration
QuickBooks is primarily an accounting platform, but its invoicing and basic quoting features are used by many UK sole traders and small businesses. For solar panel installers who are already using QuickBooks for Making Tax Digital (MTD) VAT submissions and CIS payroll, keeping quotes and invoices in the same system has obvious advantages — everything flows through to the accounts automatically without any manual reconciliation.
The quoting functionality is more limited than dedicated field service apps. There is no job scheduling, no GPS tracking, and no trade-specific workflow for managing the roof survey, installation, commissioning, and MCS certificate stages. QuickBooks works best as a secondary tool for solar installers who need robust accounting but use a separate app for the actual quoting and job management workflow.
Pros for solar panel installers: MTD VAT submissions built in; CIS deduction tracking; strong bank reconciliation and P&L reporting; widely understood by UK accountants; relatively affordable entry pricing.
Cons: Not built for field quoting — no job cards, scheduling, or GPS; quote templates are basic and not designed for itemised solar jobs; no mobile-first workflow; better as an accounting back-end than a primary quoting tool.
Which App Is Right for Your Solar Panel Installer Business?
If you are a sole-trader solar panel installer — handling everything from roof surveys to MCS documentation yourself — Sleepless Tradesman is the natural starting point. The free tier means there is no monthly overhead while you are building your customer base, and the AI-powered quoting speeds up the itemised solar panel installation quotes that customers expect. You can attach DNO application paperwork, store MCS certificate numbers against job records, and send professional invoices without paying anything until you scale up.
If you run a team of two to five installers and need proper job scheduling alongside quoting, Tradify at £29 per user per month is the best UK-focused paid option. Its trade-specific design and UK support team make it a solid choice for growing solar businesses that need visibility across multiple jobs and crews simultaneously. The Xero integration keeps your accountant happy without requiring separate data entry.
If your accounting setup is non-negotiable and your accountant is already on QuickBooks, QuickBooks may be the right base platform — but consider pairing it with Sleepless Tradesman for the field quoting and job management side, then using QuickBooks purely for MTD VAT and CIS compliance. The two tools complement each other well for a UK solar installer who needs both a strong field workflow and a clean accounting back-end.
If you are running a larger operation with multiple installation vans across different postcode areas, ServiceM8 is worth considering for its GPS dispatch and real-time crew tracking. Just budget time for configuring UK VAT rates and CIS manually, as the platform's default setup reflects its Australian origins.
Frequently Asked Questions
What is the best quoting app for Solar Panel Installers in the UK?
Sleepless Tradesman is the top free option for solar panel installers — no monthly subscription on the free tier, AI-powered quoting, and UK VAT/CIS support built in from the start. For teams needing full job management and scheduling, Tradify at £29 per user per month is the best UK-focused paid option. ServiceM8 suits field-service-heavy workflows with multiple crews, while QuickBooks works best for solar panel installers who need integrated MTD VAT and CIS accounting rather than a dedicated field quoting tool.
Is there a free quoting app for Solar Panel Installers?
Yes. Sleepless Tradesman offers a free tier with no monthly fee covering AI-powered quoting, invoice sending, and job tracking — well suited to sole-trader solar panel installers getting started or those who want to try the platform before committing. Other platforms on this list offer limited free trials (typically 14 to 30 days) but require a paid subscription for ongoing use. ServiceM8 has a restricted free plan but limits the number of jobs per month, which makes it impractical for active installers.
What features should Solar Panel Installers look for in quoting app software?
Solar panel installers should prioritise software that handles MCS certification record-keeping, supports multi-line solar panel installation quotes (covering panels, inverter, battery storage, mounting, and labour separately), and correctly applies the 0% VAT rate for residential energy-saving materials. UK CIS compliance for subcontractor payments is essential if you use subbies. Other important features include document and photo attachments for DNO applications and roof survey notes, a saved product library for EV charger add-ons and battery storage options, and a mobile-friendly interface for use on site.
