Hertfordshire premises support
Lightning Protection Testing in Hertfordshire
Arrange inspection and testing of an existing lightning protection system at your Hertfordshire premises. Our Harpenden team can discuss the installation, available records and access needed before planning a visit.
For facilities teams in Stevenage, Welwyn Garden City and Hemel Hempstead, the enquiry should include roof-access restrictions, previous findings and any building work that may have affected the system.

Lightning Protection Testing for Hertfordshire premises
Roof works, plant replacement and changes to a buildingโs exterior can affect access to lightning protection components. At a Welwyn Garden City office or a Hemel Hempstead industrial premises, explain what has changed since the last inspection rather than relying only on an old site drawing.
A rural property near Hertford may have a different arrangement of buildings and earth termination points from a town-centre site in St Albans. Identify the structures and installed systems included in the enquiry; coverage and test access need to be established for the individual property.
The work in scope
Lightning Protection Testing: what we discuss
The scope follows your premises and the information you provide. These are the main points to establish when planning lightning protection testing in Hertfordshire.
Establish the installation
Provide drawings, previous reports and a list of the structures served. Identify any parts of the system whose location or condition is uncertain.
Coordinate safe access
Explain roof restrictions, permit arrangements and any access equipment already available. Confirm the site contact who can authorise entry to restricted areas.
Review accessible components
The inspection considers accessible conductors, joints, fixings and other parts of the installed protection network within the agreed scope.
Test and record findings
Agree the accessible test points and record results against the installation information, noting restrictions that affect what can be established.
Organise maintenance follow-up
Use the findings to identify defects and further work. Repairs or design changes require their own agreed scope and records.

Preparing your Hertfordshire enquiry
Before requesting attendance, gather the latest system drawings, previous test results and details of roof or faรงade work. Photographs can help explain the enquiry, but do not replace a site inspection.
For several Hertfordshire buildings, identify the relevant system and contact for each address. Discuss access and operational restrictions separately so a shared booking does not obscure differences between installations.
Hertfordshire coverage and site enquiries
We welcome enquiries from Harpenden, St Albans, Watford, Hemel Hempstead, Hatfield, Welwyn Garden City, Stevenage, Hitchin and Hertford, as well as surrounding Hertfordshire communities. Provide the full address so the team can confirm arrangements for your premises.
Our team is based in Harpenden. For organisations with several properties, send the site list and individual requirements; attendance and scope are confirmed through the enquiry.

FAQs
Hertfordshire lightning protection testing FAQs
Practical answers to help you plan the requirements for your site.
Can you inspect lightning protection across Hertfordshire?
Contact us about existing systems in Stevenage, Welwyn Garden City, Hemel Hempstead, St Albans or elsewhere in Hertfordshire. Send the full address, system information and access constraints so we can confirm suitable arrangements.
What if roof access is restricted at our Hertfordshire building?
Tell us before booking about access routes, permits, roof restrictions and any areas that cannot be reached. The inspection scope and limitations need to be agreed; a visit should not imply that inaccessible components have been checked.
Should we mention recent roof works at a Hertfordshire site?
Yes. Describe changes to roof coverings, equipment, conductors or the building exterior and provide any associated records. At an occupied commercial site, also identify the contractor or facilities contact who can explain what was altered.
Can you test lightning protection at several Hertfordshire properties?
Send a separate address, installation description and previous report for each building. A programme covering an industrial site in Hemel Hempstead and an office in Hatfield still needs a clear scope and access plan for each location.
Does a lightning protection test include repairs in Hertfordshire?
Inspection and testing establish findings within the agreed scope. Any repairs, replacement components or further investigation should be discussed separately. Keep the resulting records together so the maintenance history remains clear.
How do we plan the next lightning protection inspection in Hertfordshire?
Ask the team to review the installed system, existing records, exposure and any recent changes. The maintenance programme should reflect those factors and the findings, rather than assuming every Hertfordshire property needs the same arrangements.
