Electrical (Part P) & Rewires

Electrical (Part P) & Rewires in London

Safe, modern electrics are essential in any home. From full rewires and board upgrades to EICR testing and EV charger installation, the right electrician in London will ensure your system is both compliant and practical for everyday use. With more devices, lighting circuits and smart technology than ever before, planning and installing electrics carefully is a key part of any renovation or extension.

Bespoke Conversions coordinates electrical works on our projects through appropriately qualified contractors, ensuring all work meets Part P of the Building Regulations and BS 7671 (the Wiring Regulations). Whether you’re carrying out a house rewire in an older property or need a consumer unit replacement and extra circuits for a new kitchen, our team makes sure the electrical scope is properly integrated with other trades. This page connects closely with house renovations and refurbishments, smart home and security, loft and garage conversions, underfloor heating and our general FAQs on project planning.

House Rewire and House Rewire in London

In many older homes, wiring may be outdated, undersized or inadequately protected. A full or partial house rewire is often recommended when:

  • You are undertaking a major refurbishment or extension.
  • Existing wiring is brittle, fabric-covered or otherwise obsolete.
  • The current installation fails an EICR (Electrical Installation Condition Report).

A complete house rewire in London typically includes:

  • New cables for sockets, lighting and fixed appliances.
  • Additional circuits for kitchens, bathrooms and utility rooms.
  • Upgraded earthing and bonding.
  • Installation of a modern consumer unit with RCD/RCBO protection.

We plan rewires alongside building works, chasing walls and lifting floors at appropriate stages and coordinating with our plastering and skimming and flooring and tiling teams for making good.

Consumer Unit Replacement and Safety Upgrades

Even where a full rewire is not required, a consumer unit replacement can significantly improve safety and compliance. This generally involves:

  • Replacing an old fuse box with a modern unit incorporating RCDs/RCBOs.
  • Rationalising circuits and labelling them clearly.
  • Testing the installation as part of the upgrade.

Your electrician in London will advise whether existing wiring is suitable to be retained or whether further works are needed.

EICR – Electrical Installation Condition Reports

An EICR is a formal inspection and testing process that assesses the condition of your electrical installation. It is particularly useful when:

  • Buying or selling a property.
  • Letting a home, where periodic inspection is required.
  • Planning major works that will interact with existing wiring.

We arrange EICR testing through qualified electricians and use the results to guide the scope of any house rewire in London or targeted remedial work as part of house renovations and refurbishments.

EV Charger Installation and Future-Proofing

With more electric vehicles on London’s roads, EV charger installation is becoming a common requirement. This usually involves:

  • Assessing existing supply capacity and consumer unit space.
  • Running suitable cabling to the charger location.
  • Installing and commissioning a compatible charging unit.

We plan EV charger installation alongside other external and driveway works where relevant, and integrate it into a broader smart home and electrical controls strategy if required.

Electrical Design for Renovations, Lofts and Extensions

On larger projects – including loft conversions, garage conversions and whole-house refurbishments – electrical design is central to how well the home works. We typically coordinate:

  • Lighting circuits (general, task and feature lighting).
  • Socket locations to suit furniture layouts.
  • Supplies for underfloor heating, heating controls and ventilation.
  • Power for appliances, extractors and MVHR systems.

Your designer may produce a lighting and power plan; our job is to ensure your electrician in London implements that plan neatly and safely, with certification issued on completion.

FAQs – Electrical & Rewires in London

How do I know if I need a full rewire?

Signs include obvious age (e.g. fabric-insulated wiring), lack of earthing, frequent tripping or a poor EICR result. We often recommend a house rewire in London when major refurbishment is planned, as it is more efficient to renew wiring while walls and floors are open.

How long does a house rewire take?

A typical house rewire may take from several days to a couple of weeks, depending on size and complexity. When combined with building works, rewiring is phased to minimise disruption and allow plastering and finishing to follow.

Is a consumer unit replacement disruptive?

A consumer unit replacement normally involves power being off for part of the day while the new board is installed and circuits tested. Most of the disruption is localised to the area where the unit is located.

Do I need an EICR if I’m not selling or renting?

While not always mandatory, an EICR is a sensible way to understand the condition of your electrics, especially if you are planning renovations or have concerns about an older installation.

Can you install an EV charger at the same time as other works?

Yes – it is often efficient to combine EV charger installation with other external or electrical works, particularly when we are already running new circuits for loft conversions, garage conversions or underfloor heating.
