Our lightning protection upgrade service brings old lightning protection systems up to date, anywhere in the UK. We check what you have, repair what is weak and add what is missing. Lightning Protection Testing UK looks after the job from start to finish.
Upgrade
Old systemWhy Do Old Lightning Protection Systems Stop Working Properly?
Rain, salt air and frost cause corrosion and loosen clips. Earth connections are essential, yet they slip, so a system that tested well years ago may not perform today. Every system has a lifespan, and wear shortens it.
How Roof Changes and Old Standards Leave Gaps
+Extensions, aerials and solar panels change how a property handles lightning. The UK passed two million solar installations in March 2026, and about 269,000 went in during 2025 alone. Many of those roofs had lightning protection systems, and nobody checked the integration.
Some older systems were designed to BS 6651, which BS EN 62305 replaced around 20 years ago. That does not make yours unsafe, but it is a strong reason for a professional review.
What Does a Lightning Strike Do to Your Property and Business?
How Often Lightning Hits the UK and How Hot It Gets
+The UK sees an estimated 200,000 to 300,000 lightning strikes every year, roughly one every two minutes. Lightning can occur in any season, and the East Midlands and the south east of England see more storms than most areas.
The air around a lightning channel can reach about 30,000°C, around five times hotter than the surface of the Sun. Lightning protection systems must give that energy a safe route to earth.
The Damage We See When Protection Fails
+In the event of a lightning strike, current can carry through wiring, ignite building materials and start a serious structural fire. It can also cause catastrophic failures in automated systems and halt a site. Lightning is electricity, so people inside can suffer injury.
Business interruption can cost more than the repair itself, and facilities without upgraded systems face a higher fire risk. Check your lightning protection testing after any storm damage or weather event.

HistoricWhich Homes and Businesses Need Better Lightning Protection?
We upgrade lightning protection systems for detached houses, period homes, farms, churches, schools, offices, hotels, warehouses, factories and tall structures such as chimneys. We also work as lightning protection contractors on industrial sites that must stay operational.
Book a review if your system has any of these:
- A design based on BS 6651 or another old standard
- An extension, a change of use, or new solar panels, aerials or plant
- Corroded or loose conductors, or no inspection records
- Worsening earth readings, a lightning strike or major roof work
Age, changes or an outdated design justify an assessment, not automatic replacement.
What Do Our Lightning Protection Services Include?
Our lightning protection services start with a site visit, an inspection and a test of your existing system. You then get a written report and a clear quote.
Most system upgrades repair or replace damaged conductors, add air terminals and bond new roof equipment. We also install surge protection devices and make earthing improvements where readings are poor. All our system upgrades are tested again, and we hand over updated records.

BS EN 62305How Do We Bring Your System in Line With BS EN 62305?
BS EN 62305 compliance is necessary for any proper upgrade. The BS EN IEC 62305:2024 series covers general principles, risk management, physical damage and danger to life, and the protection of electrical and electronic systems. Our lightning protection services meet its requirements, and our lightning protection technology is designed to match.
How Do We Protect Your Electronic Systems From Power Surges?
+Roof conductors give structural protection against physical damage, but your alarms, controls and data networks need their own. The average lightning bolt is two to three miles long, so a lightning strike nearby can push a surge into your electronic systems without a direct hit.
We check your electrical systems first. Then we fit protective devices where power and data lines enter the building, which gives stronger protection against indirect lightning effects and helps reduce damage to electronics.

The benefits of lightning protection upgrades are clear. An upgraded system improves occupant safety and helps safeguard property and sensitive electronics. Upgraded lightning protection systems also reduce fire and equipment-damage risks, and effective protection means reduced structural damage. Your business stays operational, and building occupants stay safe.
Our teamHow Much Does Upgrading Lightning Protection Cost?
Here are our rough prices, based on recent projects across the UK:
- Survey, testing and written upgrade report: £250 to £600
- Earthing improvements: £400 to £1,500
- Surge protection device fitted to a main distribution board: £350 to £1,200
- Repairing corroded conductors and clips on a typical house: £800 to £2,500
- Part upgrade for a mid-sized office, school or warehouse: £2,500 to £6,000
- Full upgrade for a large factory, hospital or heritage building: £6,000 to £15,000 or more
These prices are a rough guide, and the actual cost varies with roof size, access, property type and the work needed. Please use our contact form for an accurate quote.
AftercareHow Do You Keep Upgraded Lightning Protection Systems Working?
Weather and vandalism wear down roof metal and tall structures. We test at regular intervals, so small faults are repaired before they cause failure. UK government estate guidance recommends testing at least once a year. Our lightning protection services include maintenance, so you can maintain your lightning protection, and we maintain your records for your insurer.

How much does a lightning protection upgrade service cost in the UK?
A lightning protection upgrade costs roughly £250 to £600 for a survey, testing and written upgrade report, and £6,000 to £15,000 or more for a full upgrade of a large factory, hospital or heritage building. These prices are a rough guide, and the actual cost varies with roof size, access, property type and the work needed. Please use our contact form for an accurate free quote.
What does a lightning protection upgrade service include?
A lightning protection upgrade service includes a site visit, testing of your existing system, a roof check and a review of your records. You then receive a written report and a clear quote, and you choose what goes ahead. Most upgrades repair or replace damaged conductors, add air terminals, bond new roof equipment, fit surge protection devices and improve earthing where readings are poor, and every system is tested again with updated records handed over.
How do I know if my lightning protection system needs upgrading?
Your lightning protection system may need upgrading if it was designed to an old standard, the property has been extended, or new solar panels, aerials or rooftop plant have been added. Corroded or loose conductors, missing surge protection, no inspection records, worsening earth readings, or a recent strike or major roof work are also good reasons to book a review. Not every system must be replaced, so a professional assessment tells you what is actually needed.
Is a lightning protection system designed to BS 6651 still safe?
A lightning protection system designed to BS 6651 is not automatically unsafe, but BS EN 62305 replaced that standard around 20 years ago. That age is a strong reason for a professional review of the design, the condition of the system and the earth readings. Our engineers test the system and tell you in a written report what needs upgrading, if anything.
Should surge protection be part of a lightning protection upgrade?
Surge protection should be part of a lightning protection upgrade because roof conductors protect against physical damage, while your alarms, controls and data networks need their own protection. Nearby lightning can push a surge into electronic systems without a direct hit. We fit surge protection devices where power and data lines enter the building.
How often should lightning protection be tested after an upgrade?
Lightning protection should be tested at regular intervals after an upgrade, and UK government guidance for school estates suggests at least once a year, which suits most properties. Regular testing means small faults get fixed early. Our lightning protection services include maintenance, which keeps the records your insurer wants to see.
