PAT, or Portable Appliance Testing is a routine safety inspection of electrical appliances (fitted with a plug) to make sure they meet legal electrical safety requirements. DRA PAT Testing carry out PAT testing on building sites, at your home if you’re a sole trader, anywhere.

We can test tools that run on 230v or 110v, at the same price. We cover the North East including Newcastle upon Tyne, Durham, Sunderland, Northumberland and all surrounding areas in workplaces and homes.

We can help you maintain safe electrical equipment on your construction site through regular testing and maintenance including repair and maintenance of 110v adapted equipment. If it helps we hold CSCS visitor cards but the easiest way to ensure all equipment is tested is to bring it all to one safe location such as the site office or stores. 

We promise you that we will carry out repairs to ensure your equipment is safe, and provide you with a fully itemised PAT Test Certificate to ensure you comply with the regulations. We will do this at a time that is convenient to you (we operate 24/7) within minimal disruption to your business or home. 

We do all this at affordable, competitive PAT testing prices usually at a fixed rate so there are no shocks when the invoice comes in. 

We are also able to offer electrical testing for fixed appliances, your main wiring installation and emergency lighting.

What our clients say


These guys were recommended to us and they came in recently to do the PAT Testing. The service was first class and report very professionally presented in an easy to understand format. It is rare I give 5 stars in a review however in this case it is thoroughly deserved and would recommend DRA PAT Testing Limited to any organisation 

Dacon Fabrication, Gateshead


Excellent, friendly and efficient service. We have a lot of staff that work flexibly and Richard was happy to pop back at a later date to test their equipment which we hadn’t initially mentioned. Would recommend DRA to any organisation that needs appliance testing carried out.

PAT testing on Construction Sites

PAT testing 110v equipment is very important as it reduces the chances of an accident on site. 

If you need 110v equipment PAT testing use the contact form to get in touch, or read on for more information. 

We provide testing of fixed and portable electrical appliances on building sites and for equipment to be used on sites; we will come to the site, your home, office, etc to do the testing. We have CSCS visitor cards so can come on site, but cannot operate in hard hat areas so all equipment will need to be brought to a safe location such as the site office, store or canteen. Basically anywhere with a table will do us. 

Why do we use 110 volts on site rather than 230 volt?

If you are working on a formal building site than you are are going to need to use 110 volt equipment; this is standard practice on UK sites and is often a pre-requisite for the insurance of the site.

The Health and Safety Executive advise that tools, plugs and cable designed for domestic use are not suitable for site conditions. They further advise that site workers should use cordless tools where possible, or those that operate from an 110v (CTE) center tapped transformer so that the maximum voltage does not exceed 55v.

110v site transformers are “centre tapped“; or dual phase. What this means is the 110 volts is actually reduced further to 55 volts x 2. This much lower voltage and current is much safer to use, and it is unlikely to cause you major harm if you accidentally touched a live wire. 

How often should 110v tools be PAT tested?

Most sites will have onsite generators with 110v sockets attached to them for use by workers, however it is recommended that you have your own transformer, which should be PAT tested every 3 months whilst in use on site. Transformers convert the 240 volt current to 110 volt and then split that current into at least 2 outlets, to connect other tools; which should also be maintained to safety standards through user checks, formal visual inspections and 3-monthly PAT tests. 

PAT testing 110v equipment is very important as it reduces the chances of an accident on site. 

Booking us for site work

When we are booked to do jobs on building sites we recommend all equipment is brought to one convenient location, ideally outside the ‘hard hat’ area, so as to reduce the strain on the site insurance and reduce the risk of accident, but also as the best method to ensure all equipment is tested, and something in use on site isn’t missed. 

We can generally do the job early in the morning before you start, over the lunch breaks or after the shift finishes if you can’t afford the downtime. 

We do have CSCS cards if needed and experience working on sites, and full PPE. But the easiest method is to bring all the equipment to your site office, store or canteen where we will do the testing, preferably with a nice cup of rosy lee. 

#Top Tip

When you’re using your power tool on site does it seem underpowered? Chances are you’re using a long extension cable. You need a shorter one – the further you are from the actual power source the more likely the power to your tool will reduce. To solve this problem you need to use a shorter lead, or get a battery operated alternative.
