Behind the complex, high-stakes environment of modern healthcare estates lies a network of critical, specialised engineering services that go completely unnoticed by patients and clinical teams – until something goes wrong. From complex specialist ventilation systems protecting immunocompromised cancer patients to the high-pressure steam boilers sterilising surgical equipment, these systems are the silent lifelines of our hospitals. Managing these risks demands robust compliance, deep technical expertise, and an unwavering commitment to patient safety.
For a decade, DRLC Ltd has quietly but decisively reshaped the standard of healthcare estate compliance across the United Kingdom. Founded in 2016 in Sheffield by Chartered Engineer David Livingstone and Dr. Louise Webb, DRLC has evolved from a specialist ventilation consultancy into the UK’s premier multidisciplinary ‘One-Stop Shop’ for Authorising Engineering (AE) services.
By bridging the gap between rigorous technical standards and clinical realities, expanding into key risk areas like Confined Spaces, Working at Height, and Medical Gases, and pioneering digital compliance adoption, DRLC has established itself as the definitive choice for the ‘Best Authorising Engineer Company of the Year’ award.
The Foundation: Clinical Insight Meets Engineering Excellence
The origin of DRLC is rooted in a unique partnership. David Livingstone, Managing Director, has spent over three decades ensuring the smooth operation of public sector services, with a deep specialisation in healthcare ventilation, pressure systems, and fire safety. Dr. Louise Webb, Director, holds a medical degree alongside extensive experience in IT, project management, and academia and in 2025 completed a Master’s in Building Services Engineering through Heriot-Watt University.
This rare convergence of engineering discipline and medical insight allows DRLC to view healthcare infrastructure through a dual lens. While most engineering consultants see pipework, ductwork, and fans, DRLC sees clinical outcomes, infection control vectors, and patient pathways.
This clinical-engineering synergy was put to the ultimate test in April 2020. As the COVID-19 pandemic swept the nation, David and Louise conducted rapid research into the aerosol transmission of the virus. Recognising the threat early, they wrote and disseminated proactive ventilation management advice to all clients, helping hospitals mitigate airborne spread weeks before national guidelines were formalised. This expertise caught the attention of the NHS leadership. At 10:00PM on a lockdown night in April 2020, David received a call requesting his immediate deployment to London. By the next morning, he was on-site at the Excel Centre, serving as the Authorising Engineer for the temporary NHS Nightingale Hospital, designing and managing ventilation safety for a field hospital of unprecedented scale.
Expanding to a Multidisciplinary ‘One-Stop Shop’
Since those critical early days, DRLC has achieved remarkable growth, expanding its business footprint and service portfolio eight-fold over its first six years. The company’s expansion strategy has been deliberate and client-focused. Rather than forcing NHS trusts to manage multiple fragmented AE contracts with different sole traders – leading to communication gaps, administrative overheads, and inconsistent reporting – DRLC has systematically brought top-tier specialist expertise in-house.
Today, DRLC’s multidisciplinary team of Authorising Engineers provides comprehensive coverage across six critical engineering disciplines:
- Specialist Ventilation: Ensuring safety in ultra-clean operating theatres, isolation rooms, and pharmacy aseptic suites.
- Pressure Systems: Overseeing compliance with the Pressure Systems Safety Regulations (PSSR) for steam sterilisation and heating plant.
- Fire Safety: Carrying out Annual Audits of Fire Safety Management in healthcare premises and reviewing designs for new and refurbished healthcare buildings.
- Working at Height: Managing the high risks associated with roof access, maintenance pathways, and external structural engineering.
- Confined Spaces: Helping trusts design safe systems of work (SSOW), training regimens, and audit processes for high-risk enclosed environments.
- Medical Gas Pipeline Systems (MGPS): Formally launching in 2026 as a major new service line, completing their compliance ecosystem.
This expansion means that landmark trusts such as The Royal Marsden NHS Foundation Trust (in Chelsea and Sutton), King’s College Hospital NHS Foundation Trust in London, Guys and St Thomas’s, Sheffield Teaching Hospitals NHS Foundation Trust, and Sheffield Children’s Hospital can rely on a single, highly integrated partner to audit and secure their critical services.
Strategic Growth: Addressing Critical Gaps in Safety
In recent years, DRLC has paid close attention to where clients experience the highest administrative and safety friction. This client-centric focus has driven the highly successful rollout of their newest services.
Confined Spaces & Working at Height
Managing high-risk activities like working at height and entering confined spaces represents a significant safety and liability challenge for healthcare facilities managers. Recognising this, DRLC launched dedicated Authorising Engineer services for both disciplines.
These services have integrated seamlessly and are working exceptionally well with DRLC’s core client group. By providing clear, practical safe systems of work (SSOW), reviewing permits to work, and auditing local physical arrangements, DRLC has given estates managers the peace of mind that their teams and contractors are protected under a robust, legally compliant safety umbrella.
The 2026 Medical Gas Initiative
Medical Gas Pipeline Systems (MGPS) are among the most heavily regulated systems in a hospital, where any failure can have immediate, life-threatening consequences. DRLC’s new MGPS service line is very new, yet the market response has been immediate.
Recognising DRLC’s reputation for meticulous standards and pragmatic solutions, multiple healthcare clients have already requested pricing and tenders for their MGPS Authorising Engineer needs. DRLC is currently actively responding to these pricing requests, preparing to bring their signature ‘walk in your shoes’ auditing style to medical gas compliance across the UK.
‘Walking in Their Shoes’: A Partner-Led Philosophy
What truly sets DRLC apart from traditional auditing firms is its relationship model. In the words of Dr. Louise Webb, “There are various ways of being an auditor. One is you line everybody up, tell them what they have done wrong, and march out again. We don’t do that. We ask clients how we can help. We ask what their biggest issues are, where they think they need support. Instead of being at loggerheads with the people on the ground, we walk in their shoes.”
The regulatory framework of Health Technical Memoranda (HTMs) and Health Building Notes (HBNs) dictates that while the Authorised Person (AP) is responsible for the day-to-day operation of a service, the independent Authorising Engineer (AE) must act as the ultimate professional advisor and auditor. DRLC acts as a true partner to these APs and their Designated Persons (DPs). Rather than acting as a distant, punitive regulatory police force, DRLC’s AEs work side-by-side with estate teams, mentoring APs, participating in local Water and Ventilation Safety Groups, and helping trusts navigate the difficult balance between strict regulatory compliance and tight operational budgets.
When deviations or ‘derogations’ from HTMs are required due to structural or financial constraints, DRLC does not simply reject them. Instead, they lead comprehensive, technically rigorous risk assessments to ensure that patient safety is never compromised, documenting clear justification and formal authorisation paths that protect both the trust and its patients.
Pioneering Digital Transformation: The CompliMind Partnership
In 2026, compliance cannot be managed with spreadsheets and paper folders alone. To maintain their position at the cutting edge of healthcare engineering, DRLC has embraced digital transformation.
Recognising the potential of artificial intelligence to revolutionise estates management, DRLC partnered with CompliMind (formerly INNEX.AI) as an early AI adopter. This partnership was forged after David and Louise attended a landmark presentation by CompliMind’s founders, Carl-Magnus and Jan, at an Institute of Healthcare Engineering and Estates Management (IHEEM) national conference.
By integrating CompliMind’s advanced, regulation-aware AI systems into their auditing workflows, DRLC has dramatically accelerated their compliance validation processes. DRLC’s engineers can cross-reference local trust policies, historic derogations, and complex national standards (such as HTM 03-01 for ventilation, HTM 02-01 for medical gases, or HTM 06-01 for electrical safety) with unparalleled speed and accuracy. This ensures that their audit reports are not only delivered faster but are backed by a digitally validated, exhaustive trace of the UK regulatory corpus. This proactive adoption of AI demonstrates DRLC’s commitment to modernisation, efficiency, and future-proofing the estates they serve.
A Family-Led Legacy with a National Footprint
Despite its impressive growth, DRLC remains proudly family-run and values-driven. David and Louise are joined on the board by their children, Hamish and Melissa Livingstone, ensuring a multi-generational commitment to the company’s long-term vision. This tight-knit family governance structure means that DRLC operates with a level of agility, personal accountability, and long-term stability that larger, corporate consultancies cannot match. When an NHS trust contacts DRLC, they are not talking to a rotating cast of account managers – they are talking directly to the family directors who put their name and reputation on the line with every audit.
The scale of DRLC’s current operations is a testament to the success of this model. The company has expanded its geographical footprint to cover the entire United Kingdom, maintaining near-perfect client retention rates that reflect their partner-led ethos.
As a marker of their standing as industry thought leaders, DRLC is exhibiting at the prestigious Healthcare Estates Conference 2026 in Manchester (13th-14th October) at Stand F48. This exhibition serves as a physical hub for the company to showcase their integrated AE services, discuss their newly active Medical Gases and Confined Spaces offerings, and meet with the estates community they have supported for a decade.
