Our Company
Mayden House Ltd is a private limited company based in the United Kingdom.
We make Software as a Service (SaaS), supporting public, private and voluntary health and care providers across the UK, Australia, Canada and Ireland. For more than 25 years, we’ve partnered with NHS organisations, local authorities, charities and private providers to build technology that works in real-world clinical settings. Today, our software supports over 30,000 users and helps manage the care of more than 7 million people.
In March 2025, Mayden welcomed Cyber Media (certified with ISO 14001 Environmental Management System) into the Mayden group (“the Group”). This was followed by the acquisition of CLAI in December 2025. In March 2026, Wellola joined the Group and we will be reporting on carbon emissions for Wellola in the 2027 Carbon Reduction Plan. This has meant a need to revisit the baseline for carbon emissions reporting so as to ensure we are accurately demonstrating our approach to carbon emissions reduction.
In the interest of transparency we have included the previous baseline calculated in 2022 below, together with last year’s emissions reporting. Of note, at this time waste emissions were not included in the baseline.
Our carbon footprint as detailed in this document sets out all operations for the Mayden Group together with a total emissions figure. As noted, due to the inclusion of Wellola in the last month of the financial year we will be including the emissions for Wellola in 2027.
This Carbon Reduction Plan demonstrates Mayden Group’s compliance with the Evergreen Level 1 essential baseline sustainability standards expected by the NHS.
Employees of the Mayden Group (at 1 March 2026)
Total: 157
Full Time Equivalent: 144.7
These figures represent the Mayden Group, excluding Wellola which will be included in the 2027 report.
Commitment to achieving net zero
Mayden is committed to achieving Net Zero emissions by 2050.

| Scope 1:
As a SaaS company our product is digital. We do not produce any direct emissions as a result of developing our product. Total gas emissions in our offices are set out in scope 1 category (this was reported under Scope 2 in previous years). Scope 2: Office energy use calculated from energy bills. Mayden has installed solar panels at our main office in Bath which became operational in July 2025 and will be taken into account in next year’s emissions reporting. Scope 3: Waste emissions are reported below based on a report of our office (commercial) waste by Biffa. Waste generated in operations was not reported in our previous baseline reporting. |

*Location-based method calculates emissions based on the emissions intensity of the local electricity grid area where the electricity usage occurs. We used the UK government’s ‘Greenhouse gas reporting: conversion factors 2024’: https://www.gov.uk/government/publications/greenhouse-gas-reporting-conversion-factors-2024
**Market-based emissions are calculated based on the electricity that we have chosen to purchase, e.g. renewable energy tariff backed by Renewable Energy Certificates for the dates supplied by Pozitive Energy, and according to emissions set out below for supplier Yu Energy.
*** Market-based electricity-associated emissions have been calculated based on the fuel mix used to generate electricity supplied by our suppliers, Yu Energy between August 2024 and 31st March 2025: Coal 12.8%; Natural Gas 59%; Nuclear 9.2%; Renewable 13.2%; Other 5.7%. Yu Energy reports that this fuel mix generates CO2 emissions at a rate of 405.4g/kWh. These figures were taken from https://www.yuenergy.co.uk/app/uploads/2024/09/20240902_Fuel_Mix_23_24.pdf on 17 September 2025; and Pozitive energy between 01 April 2024 and August 2024: Coal 0%; Natural Gas 0%; Nuclear 86%; Renewable 14%; Other 0%. Pozitive Energy reports that this fuel mix generates CO2 emissions at a rate of 0g/kwh. These figures were taken from https://pe.solutions/sustainability/our-fuel-mix-100-low-carbon-energy-for-your-business/ on 25 September 2025.
****It is impractical to calculate market-based figures for working from home so emissions are shown as the average grid mix
*****The figure for business travel includes rail which is an estimated total. We plan to put in processes for the robust collection of data on rail travel in time for future reporting years aided by our new financial reporting software.
Previous baseline emissions footprint

| Scope 1:
As a SaaS company our product is digital. We do not produce any direct emissions as a result of developing our product. Total gas emissions in our offices are set out below in the scope 2 category. Scope 2: Carbon Surveys of our two Bath offices, The Old Dairy (2023) and Widcombe Crescent (2019), were carried out by the West of England Combined Authority and we will be using these for our baseline data. Scope 3: Working from Home (WFH) emissions data was continuously gathered via an internal spreadsheet where employees self-report their place of work each week, the calculations are based on official ‘UK Government GHG Conversion Factors for Company Reporting’ 2023. Our highest Scope 3 priority was to measure and reduce a subset of our emissions in line with the National Health Service supplier reporting requirements for 2024, these are categorised below. As a supplier of digital products we do not have emissions from upstream or downstream transportation, we work on a hybrid basis between 2 small offices and working from home – therefore our office waste is minor and we have measures in place for recycling and composting where possible (see projects section). Business travel data was obtained from our internal timesheet system and expense reports. There is specific outsourcing of our carbon emissions through our data hosting, such as AWS which disclose their carbon emissions separately. Employee Commuting – Commuting values were obtained from a staff survey in 2023 for which there was a 75% return rate. |

Current emissions report and new baseline emissions footprint
In March 2025 Mayden welcomed Cyber Media (which is certified ISO14001 EMS compliant) into the Group. This was followed by the acquisition of CLAI in December 2025. In March 2026, Wellola joined the Group and we will be reporting on carbon emissions for Wellola in the 2027 Carbon Reduction Plan.
This has prompted a need to revisit the baseline for carbon emissions reporting so as to ensure we are accurately demonstrating our approach to carbon emissions reduction. We now set out below the individual carbon footprint for the companies in the Mayden Group as well as the overall Group emissions. This is in accordance with the UK Government’s Procurement Policy Note 006 (formerly PPN06/21) and the NHS Net Zero Supplier roadmap.

| Scope 3:
The new baseline includes waste generated in operations which was not included in the previous baseline. This year we also include information on tech waste as well as day to day commercial waste produced at our main office at Mayden. The reduced energy usage at the Mayden offices is partly as a result of Solar Panel installation. Since September last year, we imported 26.08mWh of energy and exported 1.4mWh back to the grid. CLAI does not have an office and so there are no emissions from commuting nor any scope 1 or 2 emissions. |

*Location-based method calculates emissions based on the emissions intensity of the local electricity grid area where the electricity usage occurs. We used the UK government’s ‘Greenhouse gas reporting: conversion factors 2025’.
**Market-based emissions for Mayden is 16.91 tCO2e calculated based on the latest available fuel mix used to generate electricity supplied by our suppliers Yu Energy at the time of publication: Coal 12.5%; Natural Gas 63.2%; Nuclear 3.3%; Renewable 15.6%; Other 5.3%. Yu Energy reports that this fuel mix generates CO2 emissions at a rate of 407.1g/kWh. These figures were taken from https://www.yuenergy.co.uk/app/uploads/2025/09/20250917_Fuel_Mix_24_25.pdf on 19 May 2026
*** The commuting figures were calculated using a new employee survey for Cyber Media and Mayden employees during the year ended 31 March 2026 and converted using the Carbon Footprint Calculator https://calculator.carbonfootprint.com/calculator.aspx
****Business travel mileage was calculated using Mayden’s internal in-house expenses system to October 2025 at which time the financial tool iplicit was adopted by the Group to generate the necessary mileage reports.
*****Commercial waste generated at the Mayden offices was calculated using reports supplied by Biffa and a detailed tech waste report provided by our tech provider Blackmore rico-tech. Water waste is not considered a part of the scope 3 category “waste generated in operations”.
****** Cyber Media occupies the top floor of a two storey office building. Collection of general waste at Cyber Media is organised by a Site Management Company, the landlord, and all waste for the building is collected together and sorted for recycling at a central depot. Collection/destruction/recycling of paper documents and office equipment is arranged by Cyber Media with specialist waste disposal companies as and when required. No waste of this type was disposed of during this period.
Carbon emissions reduction commitment
To make ongoing progress towards achieving Net Zero, we have adopted the initial target of planning to reduce emissions by 50% by 2030. We should also note that we may continue to make corporate acquisitions, which will need to be included in future submissions.
The Mayden Group is committed to achieving net zero carbon emissions by 2050 for UK operations and we are engaged with sustainability.
Emissions target progress
Despite the continuation of our ongoing projects and new initiatives over the year, including the installation of our solar panels, we have not reached our ideal 10% target reduction for the year for Mayden-only total emissions which reduced from 213.39 tCO2e to 196.38 tCO2e, a 7.97% reduction.
We achieved a significant reduction in emissions for location-based Scope 1 and 2 emissions, compared with last year. This is in the context of an expanding group of companies and employees. Our total Scope 1 and 2 emissions for Mayden alone has reduced by 33.84% (a 40% reduction since the previous baseline emissions), and for the total Mayden Group during this period Scope 1 and 2 emissions has reduced by 17.37% since last year.
Carbon emissions reduction projects
Since the carbon survey of our main office was undertaken by the West of England Combined Authority in April 2023 we have responded to the following recommendations:
Upgraded office lighting to LED – we converted our main office floor from fluorescent tubes to LED, using uplighters. This both saves energy and is easier on the eyes, creating a more comfortable working environment.
The amalgamation of eight on-site electricity meters to one in preparation for the solar panel project.
Installation of solar photovoltaic panels in our Bath main office building, in operation from July 2025. Three sets of panels were installed which can provide up to 100% of daily electricity needs during the summer, reducing reliance on grid electricity.
In Autumn 2024 Mayden partnered with the University of Bath School of Management. A group of masters students joined us for a 6 week project. They undertook a double materiality assessment to help us understand carbon reduction opportunities within the business.
Continuing projects include:
In 2025 we underwent a new staff commuting survey for Mayden and Cyber Media employees to improve the accuracy of our reporting.
As a result of continuous monitoring of energy usage, Mayden is introducing smart plugs and reducing unnecessary standby power across equipment not in use.
Promotion of the cycle to work scheme.
Responsible disposal of electronic waste.
Composting office food waste.
The Sustainability Working Group continues to look for sustainable initiatives and opportunities.
New projects include:
Soft plastics recycling scheme using local recycling points.
The addition of a garden pollinator at the Bath main office.
The initial planning stages of a project to investigate the installation of insulation and secondary glazing on the top floor of our main office building at Mayden.
