What’s Involved In Rewiring


Rewiring your home is not an easy project. Its a messy job which involves chasing brickwork, lifting floors and accessing basements and attics. However its also a very important job which ensures the safety of your home and its occupants. Rewiring ensures your install complies with the latest British standard, BS7671. JRC have been involved in domestic rewiring for over 13 years.


The 17th Edition, released in January 2008, is the latest edition of BS7671, and became effective for all installations designed after 1 July 2008. This amendment provides the regulations in which all practising electricians should abide by when working on electrical installations.

An important introduction is the use of RCDs on ALL circuits. Your new installation will be equipped with a “duel RCD” consumer unit. From this unit we install wiring for ring mains circuits, lighting circuits, heating circuits, cooker and shower circuits. We also install an earth connection at the gas mains, water mains and occasionally at your boiler. We also recommend installing mains powered smoke alarms with battery back up.

Additional circuits can be accommodated such as garages, extractor fans, external sockets, external lighting and storage heaters amongst others.

All cables are concealed under floors, in attic space or within the walls of the property where possible. These cables will leave the consumer unit and be terminated at every socket, light or point within that circuit. Routing these circuits involves lifting floorboards and chiselling the internal walls. Any damage is then repaired by our experienced plasterers, should you wish to add this option to your quote. External wiring falls under different regulations, we use different cable for example, when supplying your garage.

If the property is old enough to need rewiring its likely it will be internally constructed of brick or lath/plaster. On brick work we use wall chasers and breaking hammer power tools. These tools allow us to work through the brick quickly and efficiently, however they create a lot of dust.

On lath/plaster walls we cause minimal damage to the internal strapping. Any damaged cause would be suitably bonded and plastered. We take great care to minimise the dust but inevitably it gets everywhere!

Floorboards don’t always come up easily, we use suitable tools to ensure the best cuts are made to minimise damage. We understand that potentially you may wish to re-sand your floorboards. When we remove the floorboard, we then route our cables either by boring holes in the joist or notching a small part from the timber and replacing with a metal safe plate. When the wiring is complete, the floorboards are then screwed down, or nailed if preferred.

When the cables are suitably routed and the back boxes are mounted, we then install a protective capping over the cables. While not required, it’s good practice and keeps things neat, allowing the plasterers to crack on without damaging our cables!

Before commencing rewiring we walk through the property with each customer, going into detail about how many sockets you need and positioning etc. Rewiring allows many options, you can choose additional sockets, additional lighting, you can switch existing lights from different areas, or maybe add some outside lighting. Have a chat with us, we are happy to discuss any suggestion you have.

We always make it clear what costs extra and whats included in our basic package. Generally basic rewires will include a new consumer unit, wiring for up to ten circuits, all standard accessories such as sockets and switches, plus earth bonding and smoke alarms. We can install extras such as extractor fans, shaver points, decorative light fittings, flush spotlights, carbon monoxide alarms, bespoke accessories, garage installations, aerial points and networking cables amongst others. Speak to us about anything you are considering and we will gladly offer our advice.

JRC have a combined 25 years experience in rewiring literally thousands of properties in that time. Our team has been trained specifically in this field, we have a system of work thats quick, efficient and of exceptional quality.

Unoccupied properties are generally easier therefore can be completed quicker, usually in a day or two dependant on size. We may request to work long hours to meet our deadline.

Occupied properties can produce more of challenge. We would always encourage customers to vacate overnight if possible to reduce the timescale. Understandably, this does not suit everyone. We can happily accommodate your needs, but the job will likely take a little longer if we have to make the property habitable over night.

Within our quote we will indicate a suitable timescale for your job, very rarely do we miss a deadline!

Down-light fittings are popular. We can install fittings throughout your home at a set rate and in a variety of finishes and styles.

LED lamps or LED fittings are also becoming popular, as technology improves, this option is becoming more practical and providing a real alternative to halogen.

The main benefit of using LED lamps is power consumption, a typical lamp is rated at 5-7 watts, while a standard halogen is rated at 50 watts. This can reduce your electricity bill, particularly if fitting multiple fittings. In theory LED lamps should last forever. Never having to change bulbs again is very appealing to our clients. Most manufacturers are offering lengthy guarantee on their products. LED lamps produce very little heat, therefore they can be useful in situations where heat dissipation becomes an issue.

Don’t confuse our LEDs with low quality versions which are readily available. We have sampled many fittings in order to find the best on the market, and one we are comfortable installing on our jobs. You will pay a premium for decent LEDs, cheaper options simply do not offer practical lighting solutions. The costs can soon add up, but its likely you will recuperate the initial outlay in a short time. We offer good deals on bulk buys and samples are available on request.

Included in your rewire are new fresh sockets and switches throughout. We only use quality products from reputable manufacturers ash cheap versions simply do not last the test of time. We stock certain brands but will gladly supply alternatives should you wish. Standard rewires come complete with white accessories. We also offer decorative switches and sockets in a variety of colours and finishes, at set rates and we have samples available to view. There are many options available such as dimmers, timers or sensors for lights for example. All fittings come with a standard 2 year manufacturer warranty.

We have a particular interest in external lighting. Add some WOW! factor to your building or create some ambient effects within your garden. We can install all types of lighting from soffit spotlights to decking LEDs. We keep customers updated with recent projects both on our website and at our Facebook page, where you will find new and exciting ideas.


The more preparation you can do the easier the job is!

In renovations where additional building works are involved, you may not have much preparation to do for your rewire. We would ask if possible that you remove any old carpets that you plan on binning and make the house as clear as possible for our arrival.

Occupied properties require a little more preparation. Our trained carpet fitter can lift and relay your carpets if they are being kept. We supply dust sheets throughout the property but the more dust sheets the better. If you have any old sheets around feel free to cover as much as possible, taking more care with valuable items. We can then fit our sheets on top which helps minimise the dust.

We can move around heavy furniture on our arrival but would ask you do your best to tidy away small items such as ornaments and small appliances. Rewiring can get hectic with cables all over the house, so its best to make things as clear as possible.

Things can get very noisy during the rewire, we recommend all pets are kept elsewhere! We feel its courteous to mention to adjoining neighbours about the potential noise, which should only last a few hours. We are happy to inform them for you.

Once we have chased out and completed all wiring, the walls will need plastering. This involves using a bonding coat first, then using a finish coat which can be blended into the original plasterer. We employ a full time plasterer, our quote usually includes this service but should you wish to provide your own plasterer, no problem.

Please note, you will need to decorate after rewiring!


On completion of all work we are required to carry out testing and issue certification. The tests ensure that the cables installed are fit for purpose and comply with regulations. Amongst other tests, we test for continuity of each cable and functionality of each device. The test results must comply with the parameters specified within the 17th edition wiring regulations. When we are satisfied with the results we store them on file and issue your certificate on receipt of payment. We can issue certificates via email or paper form.

Certificates guarantee our install and should be valid for the duration of the installation providing no alterations are undertaken.

As an NICEIC approved contractor all of our work and certification is backed and guaranteed by the NICEIC “Platinum Promise” Scheme, valid for six years.
