G59 Testing is an essential step in connecting solar farms now established across the UK to the network. Engineering recommendation G59 sets out the standards required for the connection of a Generating Plant to the Distribution Systems of a licensed Distribution Network Operator (DNO). It states the requirements that you must [...]
Fire protection on construction or temporary sites, marquees for instance, wouldn’t require a permanent system or the labour required to fit it. At the other end of the spectrum are an air horn or rotary fire bell, which although allowing some sort of alarm are perhaps not suitable for larger applications or where there are [...]
The main advantage of a twinflex panel is that it was one of the first widely available and easy to use 2 wire systems. This made them ideal for quick installations into houses of multiple occupancy (HMO) and small commercial premises. These twinflex fire alarm panels are available in the three [...]
Millennium and Copthorne hotels have announced to their 2000 suppliers that they are setting up a supplier registration programme meaning suppliers will now have to pay up to £510 plus VAT in order to bid for work.

This short article is designed to explain the basics of what an RCBO does, in not too technical terms.
An RCBO is a type of circuit breaker with two functions.
To protect life To protect an overload on a circuit – overcurrent and short circuit
Electricians will install an RCBO (Residual Current Breaker with Overcurrent) [...]
A Cornish gas contractor has been cleared of manslaughter but found guilty of breaching gas safety regulations following the death of a hotel guest in Newquay Great Western Hotel.
Mark Mingo replaced the central heating system for the hotel in 2005. He ordered a boiler flue attached to the hotels wall and told a colleague [...]
What is an RCD?
Electricians install RCDs to prevent electrocution by detecting the leakage current. Fuses and MCB’s protect only the installation and final appliances; they are not designed to protect people from electric shock. The common misconception is that the voltage kills whereas in reality it is the current that causes a shock [...]
Our plumbers and gas engineers are faced with all sorts of problems with oil and gas boilers on a day to day basis and have to find the solutions quickly, efficiently and most of all cheaply! No mean feat! One of the more common problems is a central heating and hot water boiler losing pressure. [...]
