Overview

The UK Renewable Energy Installers & Suppliers Database is a structured B2B dataset covering 7,241 businesses operating across the UK renewable-energy industry.

It has been created for organisations that need more than a basic list of solar companies or installer email addresses.

The database brings together renewable-energy businesses operating across technologies including:

• Solar PV
• Air source heat pumps
• Ground and water source heat pumps
• Battery storage
• EV charging
• Solar thermal
• Biomass
• Wind energy
• Hydro energy
• Other renewable-energy products and services

Businesses are classified by their primary technology, wider technologies and services, business role, organisation type and location, allowing the database to be segmented for specific B2B requirements.

The final dataset contains 5,878 installers, 1,157 businesses operating as both installers and suppliers, and 206 suppliers.

Database Description

This database has been developed as a research-enriched view of the UK renewable-energy business market, rather than as a single-source directory export.

Records have been qualified, consolidated, deduplicated and enriched using a combination of public business information, company websites, official registers, certification information and other publicly available sources.

Each record can include:

• Company identity and business type
• Renewable-energy technologies and services
• Website
• Business email
• Telephone number
• Full business address
• Decision-maker information where available
• MCS certification information
• Other industry accreditations
• Companies House number and company status
• Google rating and review information
• A supporting public evidence source
• Verification and research dates

A significant proportion of the database has also been cross-referenced against the official MCS installer directory.

The final database contains 5,443 official MCS directory matches, representing approximately 75.2% of all records.

Companies House enrichment has also been undertaken, with 6,275 businesses confidently matched to a Companies House number, representing approximately 86.7% of the database.

Where a Companies House match could not be established with sufficient confidence, a speculative company number has not been inserted.

---

Renewable-Energy Technologies Covered

The database provides coverage across both established and emerging renewable-energy technologies.

Primary Technology Breakdown

The Primary Technology field provides the main classification, while the Technologies / Services field preserves more detailed information about the activities of individual businesses.

For example, a company may be recorded as:

Solar PV; Battery Storage; EV Charging

or:

Air Source Heat Pumps; Ground / Water Source Heat Pumps; Solar PV

This makes it possible to identify both specialist companies and businesses operating across several renewable-energy technologies.

---

MCS Installer Data

A major feature of the database is the inclusion of official MCS-related information.

The final dataset contains:

• 5,443 official MCS directory matches
• MCS Certification Number
• MCS Certification Body
• MCS Certified Technologies
• MCS Status
• MCS Checked Date

This allows users to distinguish businesses that have been matched against official MCS information from companies whose MCS status has not been confirmed.

This can be particularly useful for organisations targeting certified installers of Solar PV, heat pumps and other eligible renewable-energy technologies.

---

Companies House Information

Where a reliable match could be established, the database includes:

• Companies House Number
• Companies House Status

A total of 6,275 businesses have confirmed Companies House numbers.

Company statuses represented in the dataset include Active, Active – Proposal to Strike Off, Liquidation, In Administration and Voluntary Arrangement, where applicable.

Some businesses could not be safely connected to a live Companies House company because they may operate as sole traders, trading names, dissolved entities, non-UK entities or businesses for which multiple possible company matches exist.

These records have not been assigned guessed company numbers simply to increase coverage.

---

Accreditations

In addition to MCS information, the database contains an Other Accreditations field.

Identified accreditations currently include organisations and schemes such as:

• NICEIC
• NAPIT
• TrustMark
• RECC
• EVCC

Approximately 4,545 businesses – 62.8% of the database – contain additional accreditation information.

This provides another useful way to segment renewable-energy and electrical installation businesses.

---

What Makes This Database Different?

This database has been built to provide a broader and more research-ready view of the UK renewable-energy market than is normally available from a single directory or contact list.

More Than a Renewable-Energy Company List

Many publicly available renewable-energy directories focus on one technology, one certification scheme or one type of business.

This database brings together:

Installer and supplier classifications · renewable-energy technologies · business contact information · MCS data · Companies House information · industry accreditations · geographic segmentation · Google business data · supporting public evidence

within one structured dataset.

It is therefore better described as a UK renewable-energy business intelligence dataset than simply an email list.

Multi-Source Research

The database is not dependent on a single directory.

Information has been consolidated, qualified and enriched using multiple public and official sources where appropriate.

Evidence-Backed Records

A Primary Evidence URL is available for 7,167 records – approximately 99% of the database.

This provides a supporting public source that users can consult when additional verification is required.

High Contact Coverage

The final database provides:

• Email information for 100% of records
• Phone information for 98.9%
• Website information for 92.1%
• Full business addresses for 100%

Technology-Level Segmentation

Users can distinguish dedicated Solar PV installers, heat-pump specialists, EV charging businesses, battery-storage companies, renewable-energy suppliers and companies operating across multiple technologies.

Official Register Enrichment

The dataset incorporates extensive MCS and Companies House research, bringing information that would normally need to be consulted across separate directories and registers into a single structured file.

This is an unusually comprehensive UK renewable-energy business dataset, combining installer and supplier information, technology classifications, MCS certification data, Companies House identifiers, accreditations, business contact information and public verification evidence in one structured Excel database.

This combination of business, technology, certification, registration and contact data is difficult to obtain from any single public directory, making the database particularly useful for organisations that need a broader and more research-ready view of the UK renewable-energy market.

---

Research & Data Quality

The database has undergone several stages of processing and enrichment, including:

• Renewable-energy relevance screening
• Company and record qualification
• Dataset-wide duplicate checking
• Duplicate consolidation
• Business-role classification
• Technology classification and normalisation
• Website enrichment
• Telephone consolidation
• MCS directory cross-referencing
• Companies House matching
• Accreditation enrichment
• Geographic standardisation
• Evidence-source retention

Where information could not be established with sufficient confidence, the approach has generally been to leave the field unconfirmed rather than insert unsupported information.

Because businesses, websites, certifications, company statuses and contact information change over time, individual records should still be independently checked where current accuracy is critical.

---

Email Data

A Main Email is populated for all 7,241 records in the current database.

Email information has been compiled from official directory information, company websites and other publicly available business sources where available.

The database also contains Email Source and Email Last Checked fields to provide additional context.

Business email addresses and mail-server conditions can change over time. Customers undertaking large-scale outreach should therefore run appropriate email validation before launching a campaign.

GDPR & Responsible B2B Use

The database has been compiled primarily from business-facing information, official registers, public directories, company websites and other publicly accessible sources.

It is supplied for purposes such as legitimate B2B research, market analysis, supplier identification, partnership development, sales prospecting and related commercial research.

Purchasers are responsible for ensuring that their own use of the information complies with applicable legislation and regulations, including where relevant the UK GDPR, Data Protection Act 2018 and Privacy and Electronic Communications Regulations (PECR).

Purchase or availability of a contact within this database does not, by itself, establish a lawful basis for every form of direct marketing.

Users should establish an appropriate lawful basis where required, respect suppression and opt-out requests, avoid indiscriminate messaging and independently verify information where current accuracy is material to their intended use.
