Responsible Fire Engineering and Fire Risk Management in all sectors

LWF is aware of the increasing pressures on business in all sectors to be more efficient in every way.  We aim to assist you in meeting those demands, whatever your requirements, and to do so while reducing our own carbon footprint.

You can read more detailed information on our work in specific sectors below, or call Peter Gyere on 020 8668 8663 if you would like to know more about how LWF work to minimise environmental impact during their fire engineering and safety projects.


LWF has significant experience in applying fire engineering measures to some of the country’s finest buildings where special consideration must be given to the protection of the building fabric. Creative and sympathetic specialist fire safety measures have been utilised to ensure minimal impact on protected and historic buildings.

Leisure & Entertainment

LWF has provided fire safety services to a wide variety of Leisure and Entertainment complexes. The services range from the provision of fire engineered advice for crowd evacuation to risk assessment for numerous West End Theatres.

Industrial Buildings & Warehouses

LWF has developed fire engineering design and provided fire risk assessment advice to several new industrial building schemes, where an understanding of the buildings use and the processes undertaken within the building is critical.


Our fire engineering experience for transport systems is wide-ranging and encompasses many aspects of the operators business. Fire safety services have been provided for the design of a new station complex; the fire risk evaluation of existing stations; the determination of systems of risk management; detailed fire safety compliance inspections and management/definition of fire safety risk in above-ground buildings portfolios.

Commercial Office Developments

LWF has considerable fire engineering development experience through our involvement in the development of new office buildings and refurbishment of existing buildings. Our creative fire safety designs have incorporated the use of innovative materials as well as areas such as atriums, high reception spaces and large open plan office areas.

Atria and Shopping Centres

With the development of larger and more complex buildings, LWF has gained considerable experience in providing fire engineering advice for buildings incorporating atria and other open spaces which are likely to have high volume footfall and require innovative fire risk assessment and design.


Fire safety experience in this sector has been gained in all types of public and private educational premises, from simple fire risk assessments to schools and colleges, to the development of performance-based designs for new and existing universities


LWF has extensive experience of working within the healthcare environment providing fire engineering and fire risk assessment services directly to NHS Trusts, Private Health Organisations and Consortia under PFI schemes.

  • Facilities Management & Fire Safety - Fire Development & Human Behaviour - Part 5

    In LWF’s blog series for those who work in facilities management, or who have an interest in or responsibility for fire safety, we have been looking at human behaviour when a fire starts and is developing. In part 4, the necessity of interesting and instructive fire safety training to impress the need for immediate and appropriate action was outlined. In part 5, we look at ‘panic’.The thought that people react to a fire situation...


  • Fire Engineering Design and Risk Assessment - Sprinkler Installation Design - Part 38

    In LWF’s fire engineering blog series for architects and others in the building design business, we have recently been looking at the design of sprinkler system installations. In part 37, the importance of a providing a sufficiently reliable water supply was discussed. In part 38, we talk about the need to ensure design objectives are met through thorough commissioning and testing of the completed installation.Unlike the majority of other piped installations, a sprinkler system...


  • Fire Engineering Design and Risk Assessment - Sprinkler Installation Design - Part 37

    In LWF’s Fire Engineering blog series for Architects and others in the building design business, the use of sprinklers as a method of fire suppression is being explored. In part 36, the sprinkler system grid design was discussed along with the graphs to be produced which contain data on demand curves. It was ascertained that the point at which the most favourable curve intercepts the pump curve at its highest point is known as Qmax,...


  • Facilities Management & Fire Safety - Fire Development & Human Behaviour - Part 4

    In LWF’s blog series for those who work in Facilities Management or who have an interest in or responsibility for Fire Safety, we have been looking at people’s reactions to a fire starting and their actions resulting from that. In part 3, the fact that other matters may seem pressing to individuals in a fire situation – such as settling a bill or getting a meal they’d already paid for – and the resulting actions...
