Audit & Assurance Services
Complete peace of mind
That’s what audit services from Rayner Essex give you.
Our Chartered Accountants provide expert audit and assurance services to businesses across London and throughout the UK.
A statutory audit provides more than reassurance that your financial statements have been prepared in accordance with the relevant financial reporting requirements. It can also give shareholders, lenders and other stakeholders greater confidence in your financial information and provide valuable insight into your business.
Our experienced auditors take the time to understand your business, its financial reporting risks and the systems and controls relevant to the audit. Where we identify weaknesses or opportunities for improvement, we provide clear, practical recommendations to help strengthen your financial processes and controls.
Whatever your audit and assurance requirements, Rayner Essex combines technical expertise with constructive challenge and practical insight to strengthen your financial processes and support informed business decisions.

Does your company need an audit?
You may qualify for an audit exemption if your company meets at least two of these criteria:
Annual turnover of £15m or less
Gross assets worth £7.5m or less
50 or fewer employees
(on average)
What’s the difference between audit and assurance?
A business or stakeholder may identify a particular need to gain assurance in a specific area of the company’s accounting function or financial statements. We work together with our clients to agree on a specific scope of work, the procedures to be carried out and a limited assurance report is issued to the company once we have completed our work.
An assurance review provides less assurance than an audit but more than a standard accountants’ report. Examples of the type of assurance work which a company may wish to be carried out are a review of the effectiveness of the company’s internal controls and IT systems, due diligence reporting and a review of grant claims.
Audit & assurance FAQs
This will vary depending on the complexity of the company, number of transactions during the year and if we identify any significant issues during the audit process. We will agree an audit timetable with you at the outset so that the audit is carried out during a period which is convenient for you, whilst ensuring that any reporting deadlines are met. We will keep you updated throughout the audit process so that you are aware of the status of our work and we can all agree on a plan to completion.
The statutory audit process is governed by International Auditing Standards and whether we deem an area to be material to the company’s financial statements. So it is not really possible for you to decide which areas of your business we audit. However, through discussions with you, we can identify areas of potential risk and tailor our testing accordingly.
Confidentiality is at the heart of our ethics at Rayner Essex and information from audits is never shared with people who are not authorised to access it. Written consent from a client is required before sharing any confidential audit information with a third party. If the company is non-small then our full audit report will be filed online with Companies House as part of the annual company’s accounts. If your company is small, reference to our audit report conclusion will be made in the company’s filleted accounts.
A company may need a statutory audit if it does not qualify for audit exemption under the UK small company rules. For financial years beginning on or after 6 April 2025, a company will generally qualify as small if it meets at least two of the following criteria: annual turnover of no more than £15 million, gross assets of no more than £7.5 million and an average of no more than 50 employees.
However, some companies may still require an audit because of their group structure, regulatory requirements, governing documents or requests from shareholders, lenders or investors.
Yes. A small company may still need an audit even if it falls below the statutory audit thresholds. This can happen because it is part of a larger group, operates in a regulated sector or has an audit requirement within its governing documents. Shareholders may also request an audit in certain circumstances.
If you are unsure whether your company qualifies for audit exemption, it is important to consider both the company’s individual circumstances and its wider group structure.
Yes. A company can choose to have an audit even when there is no statutory requirement to do so. A voluntary audit can provide additional assurance over financial information and may help businesses meet the expectations of shareholders, lenders, investors or other stakeholders.
It can also provide greater confidence in financial controls and identify areas where processes could be strengthened.
