Who we are
Homes to factoriesWhy Lightning Protection Services Matter for Homes, Shops and Factories
The UK sees an estimated 200,000 to 300,000 lightning strikes each year. That is around 550 to 820 a day, though most arrive in bursts during storms. Around the world, lightning hits the ground about 100 times every second.
Some days are far worse. Between 17 and 21 July 2014, 62,277 strikes were recorded across the UK. On 9 August 2019, 12,370 strikes hit mainland Britain, and lightning-related faults played a part in a power cut that reached about one million customers.
This is why lightning protection matters. A storm does not need to be right above you either. If you can hear thunder, you are already close enough to be struck.
How Does a Lightning Strike Affect a Property?
+Lightning is one of nature's destructive elements. The air around a lightning flash can reach temperatures of 30,000°C, about five times hotter than the surface of the Sun. A single bolt can carry up to one billion volts.
The channel looks wide, but it is only 2 to 3 centimetres across. It can stretch for 2 to 3 miles and the discharge moves at around 270,000 miles per hour. A poor set-up can lead to cracked brickwork, fire and severe structural damage.
Is a Direct Hit the Only Risk to Your Electronic Equipment?
+No. A strike can send energy along power, phone and data cables and push damaging voltage spikes into nearby properties. That puts your electronic equipment, alarms and control panels at risk, even when the roof is untouched.
If your business depends on tills, servers or machines, one spike can stop trade for days. The value of the kit inside premises is increasing year on year. Changing weather patterns make it hard to say where the next thunder storm will land.
What Does a Lightning Protection System Do, and What Can It Not Do?
A lightning protection system gives a strike a safe path to earth. It catches the current, carries it down and spreads it safely into the ground. It does not attract lightning, and no system can promise a structure will never be struck.
What it does is cut the chance of fire, dangerous sparking, data loss and harm to people. We plan for both the outside and the inside of the structure in every design.
What Parts Make Up a Lightning Protection System?
+The outside set-up has air terminals on the roof, down conductors along the walls and earth electrodes in the soil. Many people call the roof part a lightning conductor. We also bond nearby metal parts together, so no dangerous voltage gaps appear inside.
On a historic building, we fix each lightning conductor so it hardly shows. The job is to protect the structure without spoiling how it looks.
How Do Earthing Systems and Surge Devices Work Together?
+The outside set-up handles the main current, and earthing systems give it somewhere safe to go. Surge protection devices then stop voltage spikes reaching the wiring inside. Many owners miss this aspect.
One device rarely covers everything. We often fit coordinated Type 1, Type 2 and Type 3 devices at different points, which gives your electronic equipment better protection. We follow BS 7671:2018+A4:2026, the current UK Wiring Regulations.

Our servicesWhich Lightning Protection Services Do We Offer Across the UK?
Our lightning protection services cover the whole job, from the first check to the paperwork at the end. Here is what we offer:
- Risk assessment to work out what your site needs
- Design and installation of new systems
- Testing, including earth testing, on existing systems
- Maintenance and upgrades for older systems
- Inspection after a strike
You pick what you need, and we do the rest.
Which Properties and Situations Lead People to Call Us?
Homeowners and business owners call us for different reasons, but the worry is the same. They want the next storm to pass without a bill. Our domestic and commercial clients get the same care.
What Do Homeowners Usually Ask Us For?
+Most call after a storm hits close by, or after an insurer asks for a certificate. Detached houses on high ground, period homes with tall chimneys and flat blocks with exposed roofs are common. Others are adding an extension, or find an old installation with no test record.
What Do Hotels, Restaurants, Shops, Offices, Factories and Clinics Need?
+A restaurant loses its tills and card machines. A factory line stops, and a clinic cannot risk losing power or records. In the event of a close strike, each of these sites needs a safer environment for staff and visitors.
Churches, manors and other historic buildings call us too. These need care, because the fabric matters as much as the cover.

Level of coverHow Do We Decide the Right Level of Cover for Your Site?
Every job starts with a lightning risk assessment. We check height, location, construction, materials, use and the cables that enter the premises. We also check a lightning strike atlas for your area. The atlas shows how often storms hit nearby.
The main UK framework is the British Standard BS EN IEC 62305:2024, a four-part series. It covers general principles, risk management, physical damage and life safety, and the electrical and electronic systems inside structures. Two buildings of the same size can need very different designs, so we never copy and paste a quote.
What Standards and Safety Measures Do We Follow?
Our work must meet building regulations, insurer requirements and BS EN 62305. We only sign off a compliant system, and we assist with insurer paperwork when you need it. Safety measures on site include roof access checks, safe working at height and clear notice of any short break in power supply.
Regular checks are essential, so we also undertake periodic inspections and supply you with written records. Skipping them is how a good system quietly goes bad.
Safe working
ProcessHow Does Our Process Work From First Call to Certificate?
You tell us about your site and your access requirements, such as roof access, opening hours and alarm settings. We visit, carry out the assessment and send a clear price. We plan each job for efficiency, so we are not on site longer than needed. Then we agree a date that suits you.
We undertake the work at times that suit your site. Our specialist crew installs the system, checks every joint and the complete earth connection, then hands over your certificate. You get peace of mind plus proof for your insurer.
Why Do Homes and Businesses Choose Our Team?
Our team is fully trained, qualified and used to older and newer structures alike. We have the knowledge to spot weak earth connections, corroded fixings and missing bonds that others walk past. You deal with specialist people, not a call centre.
As lightning protection contractors, we explain things in plain words. Our solutions are built around your site, your budget and your insurer. You get honest advice, even when that means a smaller job than you expected.

What does a lightning protection company do?
A lightning protection company designs, installs and tests systems that give a strike a safe path to earth. At Lightning Protection Testing UK, our specialist engineers also fit surge protection and look after each job from the first visit to the final certificate.
Does a lightning protection system attract lightning?
A lightning protection system does not attract lightning. It catches the current and carries it safely into the ground, which cuts the chance of fire, dangerous sparking, data loss and harm to people, although no system can promise a structure will never be struck.
Do I need surge protection as well as lightning protection?
Yes, you need surge protection as well as lightning protection, because a strike can push damaging voltage spikes along power, phone and data cables even when the roof is untouched. We often fit coordinated Type 1, Type 2 and Type 3 devices at different points to give your electronic equipment better protection.
Will a lightning protection company give me a certificate for my insurer?
A lightning protection company like ours hands over a certificate once we have checked every joint and the complete earth connection. We also assist with insurer paperwork, so you have proof of compliant work whenever your insurer asks for it.
