How Much Do Home Rewires Cost in St Andrews?
If you live in an older property or are planning a major renovation, you may be wondering how much do home rewires cost in St Andrews? Rewiring a house is a significant electrical project, but it can also be an important investment when existing wiring is outdated, damaged or no longer suitable for modern electrical demands.
There is no fixed price for a home rewire because every property is different. The size of the house, age of the installation, condition of the existing wiring, accessibility and number of electrical points can all affect the final cost.
As a general 2026 guide, published Scottish rewire pricing commonly places a standard three-bedroom home somewhere around £3,500–£6,000, although more complex properties can cost considerably more.
DGEC provides domestic electrical services and full or partial rewiring throughout St Andrews and the surrounding Fife area.
What is a home rewire?
A home rewire involves replacing some or all of the electrical wiring within a property.
The purpose is to replace outdated or deteriorated cabling and bring the electrical installation up to appropriate modern standards.
A complete rewire can involve replacing:
- Electrical cables
- Sockets
- Switches
- Lighting circuits
- Power circuits
- Consumer unit
- Earthing and bonding components
The exact work depends on the condition of the existing installation.
Not every older property automatically requires a complete rewire. An electrical inspection can establish whether the existing wiring needs replacing or whether specific remedial work may be sufficient.
How much does a house rewire cost in St Andrews?
The cost of rewiring a house depends heavily on its size and complexity.
As a broad Scottish guide, a typical three-bedroom property can cost approximately £3,500–£6,000 for a full rewire, while larger or more complicated properties can exceed this range.
Other 2026 Scottish pricing guides place typical three-bedroom rewires around £4,500–£7,500 in some areas, demonstrating why a property-specific quotation is important.
These figures should be treated as general market guidance rather than a quotation from DGEC.
A home in St Andrews may cost more or less depending on its individual characteristics.
Do you always need a full rewire?
No.
One of the most important points to establish before spending thousands of pounds on a rewire is whether the entire electrical installation actually needs replacing.
An inspection can reveal that some components are outdated while the existing wiring remains suitable.
For example, you may need a consumer unit upgrade, additional circuits or targeted remedial work rather than a complete rewire.
DGEC provides full and partial rewiring services and can assess the existing installation before recommending the appropriate approach.
This can prevent homeowners from paying for unnecessary work.
What is included in a full home rewire?
A full rewire is more than simply replacing cables.
Depending on the property and specification, the work can include:
- Removal of outdated wiring
- Installation of new cables
- New power circuits
- New lighting circuits
- Socket installation
- Switch installation
- Consumer unit upgrade
- Earthing and bonding
- Testing
- Certification
The exact specification should be agreed before work begins.
Homeowners should also consider where they want sockets, switches and lighting points located.
A rewire provides an opportunity to improve the electrical layout rather than simply copying the existing arrangement.
Should you get an EICR before a rewire?
An Electrical Installation Condition Report can be a useful starting point if you are unsure about the condition of your home’s electrics.
An EICR involves inspecting and testing the electrical installation to identify defects, deterioration and potential safety concerns.
If the results show that the existing wiring remains in acceptable condition, a complete rewire may not be necessary.
If significant problems are identified, the report can help establish what needs to be addressed.
DGEC provides EICRs alongside domestic electrical services, allowing homeowners to discuss inspection findings and potential remedial work with the same contractor.

How many sockets should you have?
Older homes were often designed at a time when households used far fewer electrical appliances.
Modern homes may have televisions, computers, chargers, kitchen appliances, smart home equipment, gaming systems and other devices operating simultaneously.
If a property has too few sockets, homeowners may rely heavily on extension leads and multi-way adapters.
During a rewire, you can discuss adding additional sockets where they are genuinely useful.
This could include extra outlets beside beds, desks, kitchen worktops, entertainment areas and home offices.
Planning these requirements before the electrician begins can prevent the need for future alterations.
Can a rewire include a consumer unit upgrade?
Yes.
The consumer unit is a central part of the home’s electrical system.
Older properties may still have outdated fuse boards that lack the protection provided by modern equipment.
A rewire is often an opportunity to install an appropriate modern consumer unit alongside the new wiring.
DGEC’s home rewiring service includes fuse board upgrades as part of its rewiring solutions.
The appropriate consumer unit and protective devices should be determined according to the property’s electrical installation and requirements.
What about lighting?
Lighting should also be considered when planning a home rewire.
You may want to replace old lighting circuits or add new lighting points during the project.
Options can include:
- Ceiling lights
- Wall lights
- LED lighting
- Outdoor lighting
- Security lighting
- Dimmable lighting
- Additional switches
Installing new wiring while walls and ceilings are already being accessed can be more practical than carrying out separate electrical work later.
DGEC provides domestic lighting installations and energy-efficient electrical upgrades as part of its wider domestic electrical services.
Should you future-proof your home?
A rewire can be an opportunity to think about how you will use your home in the future.
Modern electrical requirements can include:
- Electric vehicle charging
- Solar panels
- Battery storage
- Smart home technology
- Home offices
- Additional kitchen appliances
- Outdoor electrical equipment
Planning for these requirements during a rewire can potentially reduce the need for disruptive electrical alterations later.
The exact requirements should be discussed with your electrician before the installation begins.
How long does a home rewire take?
The duration depends on the size and complexity of the property.
DGEC’s dedicated rewiring service states that most home rewires take approximately 2–5 days, while larger commercial projects can take longer.
Other Scottish electricians give broader estimates of around five to ten days for a typical three-bedroom property, demonstrating how much the schedule can vary depending on the scope and working conditions.
An empty property can generally be easier to work on than an occupied home.
Can you stay in your home during a rewire?
It may be possible to remain in an occupied property during some rewiring projects, but this depends on the scope of work and how the electrician plans the installation.
A full rewire can involve accessing walls, floors and ceilings, which means there can be considerable disruption.
You may need to move furniture and temporarily lose access to certain rooms or electrical circuits.
If possible, completing the work before moving into a property or while it is vacant can make the project easier.
Discuss occupancy with the electrician before accepting a quotation so you understand how the work will be organised.
