A full house rewire in Norfolk typically costs between £3,000 and £12,000, depending on the size of your property and the complexity of the work involved. Most electricians complete a standard three-bedroom rewire in three to five days, with minimal structural disruption when carried out by an experienced team. If your home has outdated wiring, a new consumer unit, or you are planning a significant renovation, understanding the rewiring process from start to finish helps you plan effectively and budget with confidence.
What Is a House Rewire?
A house rewire involves replacing all of the fixed wiring throughout your property, including the cables that run to sockets, light fittings, switches, and any other fixed electrical points. The consumer unit (fuse board) is also typically replaced at the same time, as it forms the central hub of your home’s electrical system.
Rewiring is a significant undertaking, but it is often necessary in older properties where the existing wiring no longer meets current safety standards set out in BS 7671, the UK Wiring Regulations. All rewiring work must be carried out by a qualified electrician and notified to Building Control under Part P of the Building Regulations.
How Do I Know If My House Needs Rewiring?
There are several signs that your property may be due for a rewire. An Electrical Installation Condition Report (EICR) carried out by a qualified electrician is the most reliable way to assess the condition of your wiring and identify any issues that require attention.
Common signs that a rewire may be needed include:
- Wiring in older rubber, fabric, or lead-sheathed cable (common in pre-1970s properties)
- Round-pin sockets or light switches, which indicate original wiring that has not been updated
- Persistent tripping of circuit breakers or fuses
- Scorch marks, burning smells, or discolouration around sockets and switches
- An EICR report with C1 or C2 codes, indicating danger or potential danger
- A fuse box with wooden elements, a cast iron switch, or no RCD (residual current device) protection
If your property was built before the 1970s and has not had a rewire in the last 25 to 30 years, it is worth having the installation assessed. Excel Electrical Services carries out EICRs across Norfolk and can advise on whether a full or partial rewire is the most appropriate course of action.
What Does a House Rewire Involve?
A house rewire follows a structured process. Understanding the stages involved helps you prepare your property and manage disruption to your household.
Stage 1: Survey and quotation
Before any work begins, a qualified electrician will carry out a thorough site survey. This allows them to assess the current installation, understand the layout of your property, and provide an accurate, itemised quote. Excel Electrical Services always carries out a pre-work survey to ensure no unexpected costs arise during the project.
Stage 2: First fix
The first fix is the main installation phase. Electricians run new cable throughout the property, chasing channels into walls where needed and threading cables through floor voids and ceiling spaces. New back boxes for sockets and switches are fitted at this stage.
You will need to remove or protect furniture and wall coverings in the rooms being worked on. Your electrician will advise on what preparation is needed in advance.
Stage 3: Second fix
Once any plastering and making-good has been completed by your decorator or plasterer, the electrician returns to complete the second fix. This involves fitting sockets, switches, light fittings, and connecting everything to the new consumer unit.
Stage 4: Testing, certification and notification
All completed electrical work must be tested to the standards set out in BS 7671. As an NICEIC approved contractor, Excel Electrical Services is authorised to self-certify rewiring work under the Competent Person Scheme, which means Building Control notification is handled directly without additional cost or delay to you.
How Much Does a House Rewire Cost in Norfolk?
Rewiring costs vary based on the size of the property, the number of circuits required, ease of access, and whether the work is being carried out as part of a larger renovation. The table below gives a general guide to typical rewiring costs in Norfolk.
| Property Type | Approx. Rewire Cost | Typical Duration |
| 1-2 bedroom flat or cottage | £3,000 to £5,000 | 2 to 3 days |
| 3 bedroom semi-detached | £4,500 to £7,000 | 3 to 4 days |
| 4 bedroom detached | £6,000 to £10,000 | 4 to 5 days |
| Large 5+ bedroom property | £8,000 to £12,000+ | 5 to 7 days |
These are approximate ranges. Your electrician will provide a fixed quote following an on-site survey. Properties with complex layouts, solid stone walls, or extensive remedial work may fall outside these ranges.
What Factors Affect the Cost of Rewiring a House?
Several variables influence the final cost of a rewire:
- Property size and number of rooms: more circuits and cable runs increase both materials and labour costs
- Property type and construction: solid wall properties (common in rural Norfolk) require more careful cable routing than cavity wall or timber frame builds
- Access: properties with accessible floor voids and loft spaces are quicker to wire than those without
- Extent of work: a full rewire from scratch is more involved than a partial rewire addressing specific circuits
- Consumer unit upgrade: replacing the existing fuse board with a modern consumer unit fitted with RCD and RCBO protection is usually included but should be confirmed in your quote
- Decoration and making-good: electrical work may involve chasing into walls and making good the plasterwork afterwards; this is typically quoted separately
Do I Need to Move Out During a Rewire?
For most domestic rewires, it is not necessary to move out, though you will need to manage without power to parts of the property at various points during the work. In practice, electricians typically restore power to each area at the end of each working day where possible.
For extensive rewires or larger properties, some households choose to make alternative arrangements for a few nights, particularly during the first fix phase when disruption is at its greatest. Your electrician will give you a clear picture of what to expect before work begins.
Why Does My Rewire Need to Be Carried Out by a Certified Electrician?
Rewiring is notifiable work under Part P of the Building Regulations in England. This means the work must either be inspected and certified by Building Control, or carried out by an electrician registered with an approved Competent Person Scheme such as NICEIC.
Choosing an NICEIC approved contractor like Excel Electrical Services means the certification process is handled directly, with no separate Building Control fee or inspection delay. You will receive an Electrical Installation Certificate on completion, which is an important document if you come to sell your property or make an insurance claim.
For landlords, rewiring work on a rental property must also comply with the Electrical Safety Standards in the Private Rented Sector Regulations 2020, which require a valid EICR to be in place for all tenancies.
How Long Does a House Rewire Take?
The duration of a rewire depends on the size of the property and the scope of work involved. As a general guide:
- Small flats and cottages: 2 to 3 days
- Three-bedroom semi-detached houses: 3 to 4 days
- Four-bedroom detached properties: 4 to 5 days
- Larger properties or those with complex installations: 5 to 7 days or more
These timescales cover the first fix only. The second fix takes place after any plastering or making-good is complete, and typically adds a further day depending on the size of the property.
Can I Have a Partial Rewire Instead of a Full Rewire?
In some cases, a partial rewire is appropriate. This might be the case if only certain circuits are found to be defective during an EICR, or if you are renovating a specific part of the property such as a kitchen or bathroom extension.
A qualified electrician can advise on whether a targeted partial rewire will address the issues identified, or whether a full rewire represents better value in the long term. In older properties with widespread deterioration, a full rewire often proves more cost-effective than addressing individual circuits repeatedly over time.
