Most homeowners never think about their wiring until something goes wrong — but the age and condition of your electrical installation has a direct impact on the safety of your home, the validity of your insurance, and the value of your property. If your home was built or last rewired before the year 2000, there is a strong chance your wiring no longer meets BS7671 18th Edition — the current UK standard for electrical safety.
Here are the most common signs that your Chelsea property may need rewiring:
If your project involves new build work rather than replacing existing wiring, find out more about our new wiring for extensions service in Chelsea.
If your electricals are otherwise in reasonable condition but your consumer unit is outdated or lacks RCD protection, a fuse board upgrade may be all your Chelsea home needs rather than a full rewire.
If any of these apply to your property, call us today on 02034 886942 for a free, honest assessment — no obligation, no hard sell, just straightforward advice from an experienced local electrician who knows Chelsea homes inside out.
A full house rewire is one of the most significant electrical projects you can undertake — and one of the most important investments you can make in the long term safety and value of your home. It involves the complete replacement of every circuit, every cable, every socket, every switch, and every light fitting in your property — from the consumer unit outwards — bringing your entire electrical installation up to BS7671 18th Edition standards in a single, comprehensive project.
Chelsea Electrical carry out full house rewires across Chelsea and South West London using only high quality materials to current wiring standards. Every rewire is planned in detail before work begins — we will discuss exactly what you need, agree the scope of works, and provide a fixed price quote before a single cable is touched. There are no surprises, no hidden charges, and no variations without your prior agreement.
A complete home rewire carried out by Chelsea Electrical includes:
Not every property needs a complete home rewire. In many cases, a partial rewire — targeting specific circuits, rooms, or areas of the installation — is the most appropriate and cost-effective solution. A partial rewire brings the affected areas of your property up to BS7671 18th Edition standards without the disruption and cost of a full rewire, and is fully certified under Part P in exactly the same way.
Chelsea Electrical carry out partial rewires across Chelsea and South West London for a wide range of situations — from single circuit upgrades to multi-room rewires following a failed EICR. Every partial rewire is scoped carefully before work begins, with a clear fixed price agreed upfront and no variations without your prior agreement.
A partial rewire is typically the right solution when:
A partial rewire targets specific circuits or areas rather than replacing the entire installation. The existing wiring that meets current standards is left in place — only the wiring that is unsafe, non-compliant, or inadequate is replaced. This makes a partial rewire significantly less disruptive and more cost-effective than a full rewire, whilst still bringing the affected areas fully up to BS7671 18th Edition standards and delivering full Part P certification for all work carried out.
If you are unsure whether your property needs a full or partial rewire, call us on 01483 356982 and we will carry out a free assessment — giving you an honest recommendation based on the actual condition of your installation, not the most expensive option.
Understanding the rewiring process removes the anxiety of the unknown — and helps you plan around the work so there are no surprises on the day. Here is exactly what to expect when Chelsea Electrical carry out a full or partial rewire at your property.
Before any work begins, one of our experienced electricians will carry out a full survey of your property. We assess the condition of your existing installation, identify everything that needs replacing, and discuss your requirements — including socket positions, lighting layouts, and any specific circuits you need. You receive a clear, fixed price quote before we start. Nothing begins until you are completely happy with the scope and the price.
First fix is where the majority of the physical work takes place. Our electricians will run new cables throughout your property — through walls, floors, and ceilings as required. This stage involves the most disruption and is when you will see the greatest impact on your home. We work methodically room by room, protecting your flooring and furnishings throughout, and always leave the property clean and tidy at the end of each working day.
Once plastering and decoration is complete — carried out by your own decorator or builder — our electricians return for second fix. This is when all the visible elements are fitted — consumer unit, sockets, switches, light fittings, and accessories. Second fix is a cleaner, less disruptive process than first fix and is typically completed in one to two days depending on the size of the property.
Once all wiring and accessories are fitted, every circuit is tested comprehensively to BS7671 18th Edition standards. This includes continuity testing, insulation resistance testing, polarity checks, and earth fault loop impedance testing on every circuit. On successful completion, your Part P certificate is issued and all work is formally notified to building control — giving you the legal documentation you need for your home insurance, mortgage lender, and future property sale. A full EICR is carried out at the same time, giving you a Satisfactory certificate that confirms your entire installation meets current UK electrical safety standards.
One of the most common questions homeowners ask before booking an electrical rewiring project is how long the work will take — and how much disruption to expect. The honest answer is that it depends on the size, age, and layout of your property. Here is a realistic guide based on our experience carrying out house rewires in Chelsea and across South West London over 14 years:
1 bedroom flat or apartment A full electrical rewire typically takes 2 to 3 days for first fix, with second fix completed in 1 day after decoration.
2 bedroom property - A full house rewire in Chelsea on a standard 2 bedroom property typically takes 3 to 4 days for first fix, with second fix completed in 1 to 2 days.
3 bedroom property -A common rewire size across Chelsea and South West London, where three-bedroom Georgian and Victorian townhouses are found throughout areas like South Kensington, Knightsbridge, and Fulham. A full rewire on a 3 bedroom townhouse or terraced property typically takes 4 to 5 days for first fix, with second fix completed in 1 to 2 days.
4 bedroom property - A full house rewire on a 4 bedroom detached or semi-detached property typically takes 5 to 7 days for first fix, with second fix completed in 2 days.
5+ bedroom property -Larger properties and period homes — which are common across Chelsea, Belgravia, and the surrounding South West London areas — typically require 7 to 10 days for first fix depending on the complexity of the installation, with second fix completed in 2 to 3 days.
These timescales are for first fix only — second fix cannot begin until plastering and redecoration is complete, which is typically carried out by your own decorator or builder. We will always give you a realistic timescale based on your specific property before work begins, so you can plan around the project with confidence.
Partial rewires in Chelsea take significantly less time — a single room or circuit can typically be completed in a single day, whilst a multi-room partial electrical rewiring project may take 2 to 3 days depending on the scope of work.
The cost of a house rewire in Chelsea depends on the size of the property, the age and condition of the existing installation, the number of circuits required, the accessibility of the wiring routes, and the specification of materials and accessories you choose. Every quote from Chelsea Electrical is free, fixed, and fully itemised — with no hidden charges, no variations without your prior agreement, and no surprises when the invoice arrives.
While every property is different, here are realistic ballpark figures based on our experience carrying out electrical rewiring across Chelsea and South West London. These are guide prices only — your fixed price quote may be higher or lower depending on the specific requirements of your property.

2 bedroom property — from £5,000 + VAT

Several factors can affect the final cost of your electrical rewiring project:
A full house rewire is not just an electrical project — it is an investment in the safety, legality, and value of your home. A property with a modern, fully certified electrical installation commands a higher sale price, satisfies mortgage lenders and insurers, and gives you complete peace of mind that your home meets current UK safety standards. For older properties across Chelsea, South Kensington, Knightsbridge, and Belgravia — where Georgian and Victorian wiring is common — a rewire is often the single most important home improvement you can make.
Once your electrical rewiring is complete, there are two important steps that follow before the project is fully signed off — and both are handled entirely by Chelsea Electrical on your behalf.
Every full and partial house rewire carried out by Chelsea Electrical is formally certified and notified under Part P of the Building Regulations — the section of UK building law that governs electrical safety in domestic properties. As a Part P registered electrical business, we handle all certification and building control notification on your behalf. You receive your certificate on completion and never have to deal with building control yourself.
Part P certification is not optional and not a formality — here is exactly why it matters for your Chelsea home:
As a Part P registered electrical business, Chelsea Electrical handle all certification and building control notification on your behalf — you receive your certificate on completion and never have to deal with building control yourself. To find out more about our full range of residential electrical services in Chelsea visit our homepage.
Once your rewiring is complete and before your Part P certificate is issued, a full Electrical Installation Condition Report is carried out on the new installation. This confirms that every circuit, every connection, and every component of your newly rewired installation meets BS7671 18th Edition standards — giving you a Satisfactory EICR certificate alongside your Part P documentation.
Two legally valid certificates. Complete protection. Everything handled by the same NAPIT registered team that carried out your rewire.
A house rewire is one of the most significant projects your home will ever undergo. The electrician you choose will be in your property for days, working through every room, every wall, and every circuit — and the quality of their work will be hidden behind your plaster and decoration for decades. This is not a decision to make on price alone.
Every house rewire carried out by Chelsea Electrical is led by a NAPIT registered, time-served electrician with a minimum of 10 years hands-on experience — overseen by our lead engineer who brings 26 years of residential rewiring expertise to every project. We have been rewiring homes across Chelsea, South Kensington, Knightsbridge, Belgravia, and the surrounding areas of South West London for years. We know these properties, we know their quirks, and we know exactly what it takes to bring them up to current standards with minimal disruption and maximum quality.
We are based in Chelsea and carry out full and partial house rewiring across South West London.

If you are unsure whether we cover your area, call us on 02034 886942 and we will confirm immediately.
Chelsea is our home town and where the majority of our house rewiring work is carried out. We cover every area of the town including the King's Road, Cheyne Walk, Sloane Square, and the surrounding streets. Chelsea has a significant proportion of Georgian and Victorian housing stock — property types that are now well past the recommended 25 year rewiring interval and frequently require full or partial rewiring to bring them up to current BS7671 18th Edition standards.
South Kensington and Brompton have a mix of Victorian and Edwardian townhouses and mansion block conversions — making this one of our most active areas for house rewiring projects. Many properties still have original wiring that has never been updated — if yours is one of them, call us today for a free rewiring assessment.
Knightsbridge & Belgravia
Knightsbridge and Belgravia are among our most active areas for partial and full house rewiring — particularly among homeowners renovating Georgian and Victorian townhouses. We cover both neighbourhoods and surrounding residential roads. Many properties here would benefit from a full electrical rewiring assessment.
We carry out full and partial house rewiring across Kensington and Earls Court. This area has a particularly diverse housing stock — from Georgian and Victorian townhouses requiring complete home rewires to mansion block conversions and modern developments needing partial rewiring or circuit upgrades.
We cover Pimlico and Fulham. Many properties in this area are period homes that have never had their wiring updated — making electrical rewiring one of the most common projects we carry out here. A free rewiring survey will tell you exactly what your property needs.
We cover Chelsea Harbour across the southern part of our service area. No travel supplement applies for properties within this area. Call us on 02034 886942 to book your free rewiring survey.

We recently had our house rewired in Chelsea and the whole experience was excellent from start to finish. The electricians were polite, tidy and explained everything clearly throughout the job. The work was completed to a very high standard and all certification was provided promptly afterwards.
After moving into an older property in Chelsea, we needed a full rewire and new consumer unit installed. Paul and his team arrived on time every day, kept disruption to a minimum and completed the work faster than expected. Highly professional service and great communication throughout.
Really impressed with the rewiring work carried out in our home in Chelsea. The electricians (Paul and Harrison) were knowledgeable, respectful and clearly took pride in the quality of their work. Everything was tested, certified and left clean and tidy once finished. Would definitely recommend.
Your questions answered honestly — by a NAPIT registered, time-served local electrical business with over 14 years carrying out full and partial house rewiring across Chelsea and South West London.
The most reliable way to know is to book a free rewiring assessment with a qualified electrician — but there are several signs that suggest your property may need full or partial electrical rewiring. These include wiring that is more than 25 years old, round pin or black sockets, old ceramic fuse boxes, rubber insulated or fabric covered cables, regularly tripping circuits, flickering lights, burning smells from sockets or switches, or a recent EICR that has returned C1 or C2 observations relating to your wiring. If any of these apply to your Chelsea property, call us on 02034 886942 for a free honest assessment.
The cost of electrical rewiring in Chelsea depends on the size, age, and layout of the property, the number of circuits required, the accessibility of the wiring routes, and the specification of materials and accessories chosen. As a realistic guide, full house rewiring in Chelsea typically starts from around £4,500 + VAT for a 1 bedroom property, rising to £25,000 + VAT or more for larger period properties. Every quote from Chelsea Electrical is free, fixed, and fully itemised — call us on 02034 886942 or complete the form below for your free fixed price survey.
A full house rewire in Chelsea typically takes between 2 and 12 days for first fix depending on the size of the property — a standard 3 bedroom townhouse or terraced property usually takes around 4 to 5 days, with larger multi-storey period homes taking longer. Second fix is carried out after plastering and decoration and typically takes 1 to 2 days. Partial rewires in Chelsea take significantly less time — a single room or circuit can often be completed in a single day. We will always give you a realistic timescale based on your specific property before work begins.
In most cases you can remain in your home during a full house rewire, though you will be without power to parts of the property on a room by room basis as work progresses. For larger properties or where the rewire involves significant structural work, a short period of temporary alternative accommodation may be more practical. We will always give you an honest assessment of what to expect before work begins so you can plan accordingly.
A full house rewire involves the complete replacement of every circuit, every cable, every socket, every switch, and every light fitting throughout the entire property. A partial rewire targets specific circuits, rooms, or areas where the wiring is unsafe, non-compliant, or inadequate — leaving existing wiring that meets current standards in place. A partial rewire is significantly less disruptive and more cost-effective than a full rewire whilst still delivering full Part P certification for all work carried out. If you are unsure which your Chelsea property needs, our free rewiring survey will give you a clear, honest recommendation.
Yes — a modern, fully certified electrical installation adds measurable value to your property and makes it significantly more attractive to buyers, mortgage lenders, and insurers. Properties with outdated wiring frequently fail mortgage surveys, and failed EICR reports can give buyers leverage to renegotiate offers downward by 15% to 35% — in one recent South West London case, a failed inspection led to an offer being reduced by £15,000. A full electrical rewiring project in Chelsea is one of the most important home improvements you can make — particularly for pre-2000 properties across Chelsea, South Kensington, Knightsbridge, and Belgravia where Victorian and Edwardian wiring is common.
Yes — any significant electrical rewiring work in a domestic property must be certified and notified under Part P of the Building Regulations. As a Part P registered electrical business, Chelsea Electrical handle all certification and building control notification on your behalf. You receive your Part P certificate on completion — the legally valid documentation that confirms your rewire has been carried out to current UK standards.
Yes — once your rewiring is complete, a full Electrical Installation Condition Report is carried out on the new installation before your Part P certificate is issued. This gives you a Satisfactory EICR certificate confirming every circuit meets BS7671 18th Edition standards — alongside your Part P documentation. Both certificates are issued by Chelsea Electrical on the day your rewire is signed off, at no additional cost.
A full house rewire carried out to BS7671 18th Edition standards using quality materials should last between 25 and 40 years before requiring significant attention. The lifespan depends on the quality of materials used, the standard of installation, and how the property is used. All rewiring carried out by Chelsea Electrical uses high quality materials to current standards and is backed by our 12 month minimum quality guarantee from the date of completion.
We can typically survey your property and provide a fixed price quote within 24 to 48 hours of your enquiry. The start date for the rewire itself depends on our current schedule — but we always aim to begin work as quickly as possible, particularly where an EICR has identified urgent remedial requirements.
