Lightning Protection Maintenance Services in Reading & London
Lightning protection maintenance is a legal requirement for any building with a system installed. Under Section 5 of the Electricity at Work Regulations 1989 (HSE), all lightning protection systems must be maintained and tested at regular intervals — typically not exceeding 12 months. Our certified team covers Reading, London, and the surrounding counties, offering comprehensive annual maintenance programmes designed to keep your system fully compliant and operational.
Where the repair and upgrading service addresses damage after it occurs, our dedicated maintenance programme focuses on prevention — identifying deterioration, corrosion, and loose connections before they compromise your system's effectiveness during a strike.
Why Lightning Protection Maintenance Is a Legal Requirement
Section 5 of the Electricity at Work Regulations 1989 places a duty on building owners and responsible persons to ensure lightning protection systems are kept in an effective and serviceable condition. Failure to do so can result in:
- Invalid building insurance
- HSE enforcement action
- Personal liability in the event of a strike
- System failure when protection is needed most
- Non-compliance with BS EN 62305:2012
- Breach of lease obligations for commercial tenants
As full members of the Association of Technical Lightning & Access Specialists (ATLAS), we carry out all maintenance to the standards required by BS EN 62305:2012 and issue certificates that satisfy both insurers and building regulators.
What Our Lightning Protection Maintenance Service Includes
Every maintenance visit covers the full system, not just the components that are easy to access. Our engineers carry calibrated test instruments and supply a written report with photographic evidence on the same day.
Visual Inspection
Full walk-round inspection of all air terminals, down conductors, fixings, clamps, and roof tape. We check for storm damage, corrosion, vandalism, and any changes caused by building work since the last visit.
Earth Resistance Testing
We test every earth electrode position using calibrated instruments, targeting below 10Ω as required by BS EN 62305. Results are recorded and compared against historical readings to identify deteriorating electrodes early.
Continuity & Bonding Checks
All down conductor continuity is verified from air terminal to earth, along with bonding connections to metallic roof services — aerials, AHUs, chillers, pipework — ensuring equipotential integrity throughout.
Surge Protection Device Testing
Where SPDs are installed (Type 1, 2, or 3), we test functionality and check for any indication lights or cartridge failures. Replacement units are carried on the van for immediate remediation.
Corrosion Treatment
Accessible joints and clamps are wire-brushed and treated with anti-oxidant compound. We replace any fixings that have corroded beyond safe use, using like-for-like materials that comply with BS EN 62305.
Compliance Documentation
On completion we issue a BS EN 62305 maintenance certificate, a detailed condition report with photographs, and a schedule of any remedial work recommended — in a format accepted by insurers and building control.
Lightning Protection Maintenance Costs
Our maintenance pricing is straightforward. The figures below cover the inspection visit, testing, corrosion treatment, and certificate issue. Any remedial work identified is quoted separately before any work is carried out — no surprises.

Transparent Reporting
You receive a written condition report, photographic record, earth resistance readings, and BS EN 62305 certificate on the day of the visit. Any remedial work is quoted separately in plain language with no obligation to proceed.
Rapid Response Coverage
Maintenance visits are scheduled at your convenience. For clients on annual contracts we offer priority scheduling, same-day emergency inspections across Reading and Berkshire, and next-day response throughout Greater London.
How Our Annual Maintenance Programme Works
Schedule Your Visit
Contact us by phone or email. We recommend booking your annual maintenance visit 11 months after the previous one to allow for seasonal variation in earth resistance readings.
Full System Inspection
Our engineer completes a detailed visual inspection and functional test of the entire system — from roof-level air terminals to below-ground earth electrodes — using calibrated instruments.
On-Site Remediation
Minor defects — loose clamps, corroded connections, failed SPD cartridges — are addressed during the same visit where components are available. Larger remedial work is quoted separately.
Certificate & Report Issued
You receive your BS EN 62305 maintenance certificate, photographic condition report, and test readings before the engineer leaves site. We then set your next annual reminder automatically.
Lightning Protection Maintenance — Frequently Asked Questions
How often should lightning protection maintenance be carried out?
BS EN 62305 and the Electricity at Work Regulations 1989 require lightning protection systems to be inspected and tested at intervals not exceeding 12 months. We recommend scheduling maintenance every 11 months so that readings are taken across different seasonal conditions, building a clearer long-term picture of system performance. Additional inspections are advisable after a suspected lightning strike, severe storm, or any significant building work near the system.
Is lightning protection maintenance a legal requirement?
Yes. Section 5 of the Electricity at Work Regulations 1989 places a legal obligation on building owners and duty holders to ensure that lightning protection systems are maintained in effective working order. Most commercial property insurers also require a current maintenance certificate as a condition of cover. Without regular maintenance, both legal compliance and insurance validity are at risk.
What is the difference between maintenance and testing?
Annual testing verifies that a system passes the required electrical standards — earth resistance below 10Ω and continuity throughout. Maintenance goes further: it includes cleaning and treating corroded joints, tightening loose fixings, replacing worn clamps, testing SPD devices, and carrying out minor remediation during the same visit. At Earthing Equipment Supplies we offer combined maintenance and testing visits at a discounted rate compared to booking them separately.
How much does a lightning protection maintenance contract cost?
A single annual maintenance visit for a standard commercial building costs between £200 and £350, which covers the full inspection, testing, corrosion treatment, and BS EN 62305 certificate. Multi-site contracts for five or more locations start from £4,000 per year and include priority scheduling, automatic annual reminders, and a dedicated account manager. All quotations are provided in writing before any work begins.
What happens if a fault is found during maintenance?
Minor defects — a corroded clamp, a failed SPD indicator, a loose fixing band — are typically resolved on the same visit where we carry stock components on the van. More significant issues, such as a section of conductor requiring replacement or an earth electrode that needs augmentation, are photographed, documented in the report, and quoted separately before any additional work is carried out. You are never charged for remedial work without prior written agreement.
Do you cover buildings across the UK?
Our primary service area covers Reading, Berkshire, Greater London, and the surrounding counties of Oxfordshire, Hampshire, Surrey, and Buckinghamshire. We offer same-day emergency maintenance response across Reading and Berkshire, and next-day scheduled visits throughout Greater London. For multi-site contracts or specialist projects, we provide full UK coverage — contact us to discuss your requirements.
