Electrical Testing & Inspection

Workplace safety is a tightly legislated area, with ever more stringent regulations requiring that all electrical equipment used in, or associated with, places of work be maintained to prevent the risk of accidents.

The main statutory regulations are: Electricity At Work Regulations (EAWR), The Provision and Use of Work Equipment Regulations (PUWER), The Health and Safety at Work Act.

As an NICEIC approved contractor we will carry out periodic inspection testing on any existing installation for compliance with British Standard BS7671 (IEE Wiring Regulations).

Portable Appliance Testing (PAT)

D & A Systems offers a simple and cost-effective solution, enabling all companies to comply with their legal obligations. We use the latest computerised test equipment and software which will enable us to produce asset registers detailing all tests performed.

Thermography

Infrared thermal imaging is an invaluable method of locating inaccessible, hidden faults quickly and efficiently. We can provide a thermal survey of plant and systems, usually while equipment and systems are in an on-load condition.

Quality Power Management

Unexplained power cuts? Circuit breakers tripping out for no reason? Power spikes? High energy use? Today's hi-tech, power-hungry businesses depend on having a clean, consistent power supply.

Voltage fluctuations, harmonic pollution, power failures, and load imbalances are increasingly common; at worst microprocessor-based equipment can be damaged, and production lost.

D & A Systems provides a comprehensive range of services to tackle these challenges, including site monitoring surveys and detailed reports.

NICEIC Approved Contractor

NICEIC is the UK electrical contracting industry's independent voluntary body. They offer leading certification services, Building Regulations Schemes, products and support to electrical contractors and many other trades within the construction industry.

NICEIC has been assessing the technical competence of electricians for over 50 years. Their aim is to protect everyone who uses electricity from unsafe electrical installations in their homes, places of work and elsewhere. To achieve this, they maintain a register of qualified, competent electricians.

They look at a representative sample of the contractor's work, their premises, documentation, equipment, and the competence of their key supervisory staff. Once contractors become registered with NICEIC, they are re-assessed on a regular basis to ensure high standards.

Safecontractor Approved

Under the safecontractor scheme, businesses undergo a vetting process which examines health and safety procedures and their track record for safe practice. Those companies meeting the high standard are included on a database, which is accessible to registered users only via a website.

Client-organisations who sign up to the scheme can access the database, enabling them to vet potential contractors before they even set foot on site. These clients agree that, as users of the scheme, they will engage only those who have received accreditation.

Over one hundred and seventy major nation-wide businesses, from several key sectors, have signed up to use the scheme when selecting contractors for services such as building, cleaning, maintenance, refurbishment or electrical and mechanical work.

Vauxhall Contractor of the Year

D & A Systems Ltd have achieved success in the award of this prestigious accolade on two occasions.

This highly sought after award was secured in the face of stiff competition from various site contractors. Selection criteria was heavily biased towards Health and Safety performance, but also taken into consideration was the number and complexity of projects undertaken, project performance and documentation through to completion.

During six years site presence, we have successfully delivered various projects, including the electrical engineering services for the introduction of the new Astra production line, the site wide public address / voice evacuation system, and the Small Construction Project Agreement which provides a turnkey solution for all small project requirements.

Airbus Gold Award

The Derek Hodgson Gold Award is presented to contractors who consistently achieve the highest safety standards whilst delivering services at Airbus UK, Broughton Centre of Excellence.

Broughton is responsible for sub-assembly and the manufacture of large components, as well as wing final assembly and wing equipping for the entire Airbus fleet. Activities in Broughton include wing skin milling, stringer manufacture, full wing equipping and wing box assembly.

D&A Systems have provided varying engineering solutions to Airbus UK over many years, including 11kv distribution network upgrade works, and A380 wing jig power and control systems.
