STRATEGIC REPORT
FOR THE YEAR ENDED 31ST MARCH 2025


The directors present their strategic report for the year ended 31st March 2025.

REVIEW OF BUSINESS AND FUTURE DEVELOPMENTS

We continue to grow our client base across all market sectors, developing client relationships and securing growth.

Turnover for the period totalled £48.3m (year ended 31 March 2024: £36.8m), an increase of 31%. Growth was driven by expansion and retention of customers across commercial, industrial, residential, education and health sectors, and by a broader customer mix that created additional opportunities.

Gross profit margin for the period was 20.7%, a marginal decline compared with the prior year, primarily reflecting increased investment in staff to support future growth. Statutory EBITDA for the period was £6.9m (year ended 31 March 2024: £5.8m), an increase of 18.5%, driven by higher turnover and effective control of central costs.

The company continued to invest in its team, with the average number of employees increasing to 98 (year ended 31 March 2024: 87). To support geographic growth, HVSS opened an office in the East of England in April 2025, and the group acquired a new office in Kettering to accommodate additional staff. This new office is due to be occupied from early 2026.

Our people are integral to the company's success. We invest in structured performance reviews, ongoing training and professional development for all employees.

We are progressing against our environmental objectives by reviewing our vehicle fleet and introducing an electric vehicle salary sacrifice scheme for employees. Two of our group sites are fitted with solar, producing over 39,000 kWh of electricity per year.

Health and safety underpins all our operations. Continued vigilance and active participation from every colleague ensures that work is carried out safely at all times. Our safety programme includes regular site inspections, toolbox talks, and mandatory training and competency checks for everyone who works on or visits our sites.

STREAMLINE ENERGY AND CARBON REPORTING

Methodology

The methodology used to determine emissions and energy consumption for the purposes of SECR reporting is based on the Green House Gas Protocol Corporate Standard Emissions have been calculated using the UK Government's GHG Conversion Factors for 2024 and 2025. Energy data has been sourced from utility bills, fuel cards, and internal records. Scope 1, 2 and 3 emissions are reported in accordance with the GHG Protocol Corporate Standard.

Energy Efficient Actions

During the year we introduced and encouraged staff to take up an electric car through a new salary sacrifice scheme, Tusker. Furthermore, we have solar installed across all group owned properties.

STRATEGIC REPORT
FOR THE YEAR ENDED 31ST MARCH 2025

PRINCIPAL RISKS AND UNCERTAINTIES
The principal risks and uncertainties facing the company are:

Regulatory

The company operates in a mature, regulated marketplace and monitors regulatory developments that could affect the business. The directors are not currently aware of any proposed changes that would materially alter the regulatory framework in which the company operates.

Compliance

The company operates a comprehensive Safety, Health, Environmental and Quality (SHEQ) framework designed to minimise risk to employees, customers, the public, and the environment. The company has an established track record and a culture of continuous improvement in these areas. HVSS holds ISO 9001, ISO 14001 and ISO 45001 certifications and maintains required Lloyd's accreditations (NERS, GIRS and WIRS) to support its operations. Business opportunities are reviewed against accreditation requirements to ensure alignment with client expectations.

Credit and cashflow risk

The company is exposed to credit and cashflow risk. This exposure is mitigated by a broad client base, sector diversification and controls over payment profiles. The company applies credit management processes to reduce the risk of client default to a manageable level and maintains active cashflow monitoring across the business.

Price risk

The company's principal price risk arises from increases in purchase costs from key suppliers. This risk is mitigated through active monitoring of purchase prices and material availability, and by making procurement decisions to optimise cost and delivery. The company has launched a procurement improvement project to enhance pricing outcomes and supply resilience.

KEY PERFORMANCE INDICATORS

The directors consider the company's principal financial performance indicators to be turnover, gross profit margin, EBITDA and turnover secured but not yet delivered. These measures together communicate the financial performance and strength of the company and are discussed in the Business Review above.

The company's main non-financial key performance indicators focus on people, since recruiting and retaining the right talent is critical to delivering our strategy and realising recent investments. The average number of employees increased year-on-year. These workforce metrics are tracked alongside training, safety and retention indicators to measure the effectiveness of our people-based investments

Our Values

Dedication

We show other appreciation and trust by being authentic and genuine through our actions and behaviours.

We focus on a healthy work life balance where everybody is responsible for looking after each other. We take time to recover and look after our mental wellbeing.

We actively seek feedback from our customers and take responsibility to strive for excellence.

STRATEGIC REPORT
FOR THE YEAR ENDED 31ST MARCH 2025

Proud

We operate a business where trust, honesty, compassion and fairness are the key foundations of our culture.

We deliver on our promises and take accountability for our actions.

We care and we are ambassadors of our company. We develop great people who nurture our relationships internally and externally.

Confident

We strive to exceed our performance, demonstrating resilience and perseverance and take responsibility for our work and behaviour.

We ensure we have a safe workplace or worksite to avoid accidents and comply with the HSE regulation.

We plan and analyse efficiently to develop solutions. We use experience and lessons learned from the past and ask others about their approach to similar problems.

Committed

By being imaginative when thinking about the future and understanding our responsibility to make a positive change.

We are open to change and committed to new opportunities within the industry. We embrace new technologies and ideas to take our business into the future.

We strive for continuous improvement and we try to do things better.

SECTION 172(1) STATEMENT
The directors have a duty to promote the success of the company by collectively and individually acting in good faith and in a way that is thought best to achieve this outcome. In doing so, the directors consider and favour long term objectives over short term goals but remain always ready to deal with urgent issues as they arise. The directors' approach is very "hands on" and they obtain information about the company's activities and performance from a pool of resources, not least from the company's talented and valued employees.

DISCLOSURE IN THE STRATEGIC REPORT
The report of the directors should be read in conjunction with the strategic report.

STATEMENT OF DIRECTORS' RESPONSIBILITIES
The directors are responsible for preparing the Strategic Report, the Report of the Directors and the financial statements in accordance with applicable law and regulations.

Company law requires the directors to prepare financial statements for each financial year. Under that law the directors have elected to prepare the financial statements in accordance with United Kingdom Generally Accepted Accounting Practice (United Kingdom Accounting Standards and applicable law). Under company law the directors must not approve the financial statements unless they are satisfied that they give a true and fair view of the state of affairs of the company and of the profit or loss of the company for that period. In preparing these financial statements, the directors are required to:

-select suitable accounting policies and then apply them consistently;
-make judgements and accounting estimates that are reasonable and prudent;
-state whether applicable accounting standards have been followed, subject to any material departures
disclosed and explained in the financial statements;
-prepare the financial statements on the going concern basis unless it is inappropriate to presume that the company will continue in business.

The directors are responsible for keeping adequate accounting records that are sufficient to show and explain the company's transactions and disclose with reasonable accuracy at any time the financial position of the company and enable them to ensure that the financial statements comply with the Companies Act 2006. They are also responsible for safeguarding the assets of the company and hence for taking reasonable steps for the prevention and detection of fraud and other irregularities.

STATEMENT AS TO DISCLOSURE OF INFORMATION TO AUDITORS
So far as the directors are aware, there is no relevant audit information (as defined by Section 418 of the Companies Act 2006) of which the company's auditors are unaware, and each director has taken all the steps that he ought to have taken as a director in order to make himself aware of any relevant audit information and to establish that the company's auditors are aware of that information.

AUDITORS
The auditors, Bewers Turner & Co LLP, will be proposed for re-appointment at the forthcoming Annual General Meeting.

ON BEHALF OF THE BOARD:





CK Beattie - Director


13th November 2025

REPORT OF THE INDEPENDENT AUDITORS TO THE MEMBERS OF
HIGH VOLTAGE SYSTEMS AND SERVICES
LIMITED


Opinion
We have audited the financial statements of High Voltage Systems and Services Limited (the 'company') for the year ended 31st March 2025 which comprise the Statement of Comprehensive Income, Balance Sheet, Statement of Changes in Equity and Notes to the Financial Statements, including a summary of significant accounting policies. The financial reporting framework that has been applied in their preparation is applicable law and United Kingdom Accounting Standards, including Financial Reporting Standard 102 'The Financial Reporting Standard applicable in the UK and Republic of Ireland' (United Kingdom Generally Accepted Accounting Practice).

In our opinion the financial statements:
-give a true and fair view of the state of the company's affairs as at 31st March 2025 and of its profit for the year then ended;
-have been properly prepared in accordance with United Kingdom Generally Accepted Accounting Practice; and
-have been prepared in accordance with the requirements of the Companies Act 2006.

Basis for opinion
We conducted our audit in accordance with International Standards on Auditing (UK) (ISAs (UK)) and applicable law. Our responsibilities under those standards are further described in the Auditors' responsibilities for the audit of the financial statements section of our report. We are independent of the company in accordance with the ethical requirements that are relevant to our audit of the financial statements in the UK, including the FRC's Ethical Standard, and we have fulfilled our other ethical responsibilities in accordance with these requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Conclusions relating to going concern
In auditing the financial statements, we have concluded that the directors' use of the going concern basis of accounting in the preparation of the financial statements is appropriate.

Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions that, individually or collectively, may cast significant doubt on the company's ability to continue as a going concern for a period of at least twelve months from when the financial statements are authorised for issue.

Our responsibilities and the responsibilities of the directors with respect to going concern are described in the relevant sections of this report.

Other information
The directors are responsible for the other information. The other information comprises the information in the Strategic Report and the Report of the Directors, but does not include the financial statements and our Report of the Auditors thereon.

Our opinion on the financial statements does not cover the other information and, except to the extent otherwise explicitly stated in our report, we do not express any form of assurance conclusion thereon.

In connection with our audit of the financial statements, our responsibility is to read the other information and, in doing so, consider whether the other information is materially inconsistent with the financial statements or our knowledge obtained in the audit or otherwise appears to be materially misstated. If we identify such material inconsistencies or apparent material misstatements, we are required to determine whether this gives rise to a material misstatement in the financial statements themselves. If, based on the work we have performed, we conclude that there is a material misstatement of this other information, we are required to report that fact. We have nothing to report in this regard.

REPORT OF THE INDEPENDENT AUDITORS TO THE MEMBERS OF
HIGH VOLTAGE SYSTEMS AND SERVICES
LIMITED


Opinions on other matters prescribed by the Companies Act 2006
In our opinion, based on the work undertaken in the course of the audit:
- the information given in the Strategic Report and the Report of the Directors for the financial year for which the financial statements are prepared is consistent with the financial statements; and
- the Strategic Report and the Report of the Directors have been prepared in accordance with applicable legal requirements.

Matters on which we are required to report by exception
In the light of the knowledge and understanding of the company and its environment obtained in the course of the audit, we have not identified material misstatements in the Strategic Report or the Report of the Directors.

We have nothing to report in respect of the following matters where the Companies Act 2006 requires us to report to you if, in our opinion:
- adequate accounting records have not been kept, or returns adequate for our audit have not been received from branches not visited by us; or
- the financial statements are not in agreement with the accounting records and returns; or
- certain disclosures of directors' remuneration specified by law are not made; or
- we have not received all the information and explanations we require for our audit.

Responsibilities of directors
As explained more fully in the Statement of Directors' Responsibilities set out on page six, the directors are responsible for the preparation of the financial statements and for being satisfied that they give a true and fair view, and for such internal control as the directors determine necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the financial statements, the directors are responsible for assessing the company's ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the directors either intend to liquidate the company or to cease operations, or have no realistic alternative but to do so.

REPORT OF THE INDEPENDENT AUDITORS TO THE MEMBERS OF
HIGH VOLTAGE SYSTEMS AND SERVICES
LIMITED


Auditors' responsibilities for the audit of the financial statements
Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue a Report of the Auditors that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with ISAs (UK) will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these financial statements.

The extent to which our procedures are capable of detecting irregularities, including fraud is detailed below:

Because of the inherent limitations of an audit, there is a risk that we will not detect all irregularities, including those leading to a material misstatement in the financial statements or non-compliance with regulation. This risk increases the more that compliance with a law or regulation is removed from the events and transactions reflected in the financial statements, as we will be less likely to become aware of instances of non-compliance. The risk is also greater regarding irregularities occurring due to fraud rather than error, as fraud involves intentional concealment, forgery, collusion, omission or misrepresentation. The extent to which our procedures are capable of detecting irregularities, including fraud is detailed below. However, the primary responsibility for the prevention and detection of fraud rests with both those charged with governance of the entity and management.
- We obtained an understanding of the legal and regulatory frameworks that are applicable to the company and determined that the most significant are those that relate to the reporting framework (Financial Reporting Standard 102 and the Companies Act 2006) and the relevant direct and indirect tax compliance regulation in the United Kingdom. In addition, the Company has to comply with laws and regulations relating to its operations and health and safety.
- We understood how the Company is complying with those frameworks by making enquiries of management to understand how the Company maintains and communicates its policies and procedures in these areas, and corroborated this by reviewing supporting documentation.
- We assessed the susceptibility of the Company's financial statements to material misstatement, including how fraud might occur by considering the risk of management override and determining revenue to be a fraud risk. We tested transactions identified back to independent evidence or source documentation. We obtained third party confirmations directly from the Company's banking partners to verify the cash held at the balance sheet date and the completeness of any commitments or contingencies.
- Based on this understanding we designed our audit procedures to identify non-compliance with such laws and regulations. Our procedures involved review of documentation, testing of specific journals identified based upon risk criteria and enquiries of management for correspondence with the relevant authorities.

A further description of our responsibilities for the audit of the financial statements is located on the Financial Reporting Council's website at www.frc.org.uk/auditorsresponsibilities. This description forms part of our Report of the Auditors.

To the fullest extent permitted by law, we do not accept or assume responsibility to anyone other than the company and the company's members as a body, for our audit work, for this report, or for the opinions we have formed.

NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 31ST MARCH 2025


1. STATUTORY INFORMATION

High Voltage Systems and Services Limited is a private company, limited by shares , registered in England and Wales. The company's registered number and registered office address can be found on the Company Information page.

The presentation currency of the financial statements is the Pound Sterling (£).


2. ACCOUNTING POLICIES

Basis of preparing the financial statements
These financial statements have been prepared in accordance with Financial Reporting Standard 102 "The Financial Reporting Standard applicable in the UK and Republic of Ireland" and the Companies Act 2006. The financial statements have been prepared under the historical cost convention.

Financial Reporting Standard 102 - reduced disclosure exemptions
The company has taken advantage of the following disclosure exemptions in preparing these financial statements, as permitted by FRS 102 "The Financial Reporting Standard applicable in the UK and Republic of Ireland":

the requirements of Section 7 Statement of Cash Flows;
the requirement of paragraph 3.17(d).

Related party exemption
The company has taken advantage of exemption, under the terms of Financial Reporting Standard 102 'The Financial Reporting Standard applicable in the UK and Republic of Ireland', not to disclose related party transactions with wholly owned subsidiaries within the group.

Significant judgements and estimates
In the application of the company's accounting policies management are required to make judgements, estimates and assumptions about carrying values of assets and liabilities that are not readily apparent from other sources. The estimates and underlying assumptions are based on historical experience and other factors that are considered relevant. Actual results may differ from these estimates. The estimates and underlying assumptions are reviewed on an ongoing basis.

A key area of significant judgement for the company is the recognition of revenue on its installation contracts.

Turnover
Turnover is measured at the fair value of the consideration received or receivable, excluding discounts, rebates, value added tax and other sales taxes.

Tangible fixed assets
Depreciation is provided at the following annual rates in order to write off each asset over its estimated useful life.
Plant and machinery - 25% on reducing balance
Fixtures and fittings - 25% on reducing balance
Motor vehicles - 25% on reducing balance

Tangible fixed assets are stated at cost less accumulated depreciation and accumulated impairment losses. Cost includes costs directly attributable to making the asset capable of operating as intended.

2. ACCOUNTING POLICIES - continued

Stocks
Stocks are valued at the lower of cost and net realisable value, after making due allowance for obsolete and slow moving items.

Financial instruments
The company is party to only the basic financial instruments such as cash, trade debtors and trade creditors. Instruments such as trade debtors and trade creditors are initially recognised at their transaction cost and reviewed at the year end for impairment.

Taxation
Taxation for the year comprises current and deferred tax. Tax is recognised in the Statement of Comprehensive Income, except to the extent that it relates to items recognised in other comprehensive income or directly in equity.

Current or deferred taxation assets and liabilities are not discounted.

Current tax is recognised at the amount of tax payable using the tax rates and laws that have been enacted or substantively enacted by the balance sheet date.

Deferred tax
Deferred tax is recognised in respect of all timing differences that have originated but not reversed at the balance sheet date.

Timing differences arise from the inclusion of income and expenses in tax assessments in periods different from those in which they are recognised in financial statements. Deferred tax is measured using tax rates and laws that have been enacted or substantively enacted by the year end and that are expected to apply to the reversal of the timing difference.

Unrelieved tax losses and other deferred tax assets are recognised only to the extent that it is probable that they will be recovered against the reversal of deferred tax liabilities or other future taxable profits.

Pension costs and other post-retirement benefits
The company operates a defined contribution pension scheme. Contributions payable to the company's pension scheme are charged to profit or loss in the period to which they relate.

Revenue and income recognition
Installation contracts have a number of major and minor components, often with different end customers. The directors group together components that are so closely linked that their commercial effect cannot be fully understood if they were reported on separately. This includes components that may not be realised until some years after the major contract work has been completed. Contracts are billed in advance for materials and then periodically as the work progresses. Where amounts billed exceed the value of the work done, the directors defer revenue within "deferred income". Unbilled work is included within "Amounts recoverable on contracts". The value of work done is assessed by the directors and the project management team, this requires a significant area of judgement on the directors' part.

3. TURNOVER

The turnover and profit before taxation are attributable to the one principal activity of the company.
