We always try our absolute best to inconvenience you as little as possible. We aim to book a pre-arranged date and time with you, although sometimes, we may have to offer you a morning or afternoon slot. If your job is urgent, we may be able to call you at short notice if we get a cancellation.

Are you insured?

Yes, we have £5,000,000 Employers Liability Insurance and £2,000,000 Public Liability Insurance.

What’s involved in rewiring my house?

We are experienced at making the rewire as hassle and mess-free as possible, but unfortunately, rewiring is disruptive and invasive work. For a full rewire, every room will need to have the following carried out:

• Furniture moved out

• Floor covering taken up

• Floorboards lifted

• Walls chased out for switches/sockets where necessary

• Dust and mess during the period of the work (although we always clean up at the end of the day)

To rewire lighting upstairs, we will probably need the loft to be cleared to gain access to the lighting points and to each switch drop.


What is an RCD and what are the benefits?

An RCD is a Residual Current Device. It’s designed to protect against electrocution and electrical fires by cutting off the supply of power when it senses a leakage of electrical current from a circuit. An RCD monitors electric currents in circuits or individual items and will switch off the electricity automatically if there is a problem. For example, if you cut through a cable with a power tool, the power switches off,  eliminating the chance of injury from electrocution.


RCDs also offer protection against electrical fires.


Do I need to use RCD protection on any of my circuits?

Under BS7671 IEE Wiring Regulations all circuits are recommended to be protected by a 30mA RCD in most domestic situations. Please contact us if you require any further information.

For Landlords and HMO Owners

How many smoke alarms do I need in a rental property?

Landlords are required to put a smoke detector on every storey and principal habitable room (e.g kitchen and living room) of a rental property. A Carbon Dioxide detector is required in any room where there is a working fireplace or solid fuel appliance.


How do I know if my property is compliant?

As a landlord, you must be compliant with Health and Safety regulations and make sure that any wiring or power device within your properties meets with the current regulations. You should have the wiring, distribution boards and power systems in your property checked regularly to reduce the risk of overloading devices or fire.


How many sockets should be in each bedroom of an HMO?

A standard bedroom should have a minimum of 3 sockets, although we would always suggest that the 3 sockets should be fitted as twins, giving the user more flexibility and preventing the likelihood of using dangerous extensions. In other parts of the house, socket numbers can vary depending on room size and function. If you have any further questions, do contact us.

For Owners and Managers of Commercial Properties

Why should I use an NICEIC contractor?

Working with electricity requires a highly qualified electrician to carry out electrical work to a safe and high-quality standard, which is why it’s critical that you choose a business that’s NICEIC approved.


Electricians registered by NICEIC are assessed on a regular basis to ensure they are competent and authorised to self-certify work. As NICEIC-accredited electricians, we also have a Platinum Promise which covers electrical work up to the value of £25,000. This is a protection entity which only an NICEIC approved contractor can offer.


These are the key reasons you should use an NICEIC approved electrical contractor:

  • We’re annually assessed by NICEIC
  • We have public liability insurance
  • You have access to an independent complaints process
  • We’re approved to carry out all forms of inspection and testing from minor works to full installations and fire alarms, emergency lighting, periodic tests and inspections.


What are the Legal Requirements for businesses?

The law requires that all business owners, their directors, managers and employees comply with “The Electricity at Work Regulations”. The law requires that all electrical systems must be maintained to be safe at all times and that no system or part of it may give rise to danger during either normal operation or under fault conditions.


Test reports, together with other preventative maintenance documentation will form the basis of proof that you have done this and will provide your best defence against prosecution should the need arise. Business duty holders are responsible for setting up adequate maintenance programs and must assess the needs and frequency requirement of testing, maintaining and monitoring electrical systems and equipment.


Why do I need to have my wiring tested?
Electricity will always find the easiest path to earth. Any faults or weaknesses within your electrical installation or portable appliances can go undetected. In the event of another fault developing, this could lead to serious risk of fire, electrocution or death.


For example, a 13-amp ring-main without earth continuity could render all metal parts of appliances plugged into it “LIVE” if one item on the ring developed a fault to earth. Fixed wiring testing will accurately identify faults, their locations and usually the recommended solution.


Will testing cause a lot of disruption to the power?

A short power outage can be expected on each circuit within the system but because most of the testing is carried out whilst the system is still live, these outages can be planned around your daily activities.
