Unsure if your Hertford home needs a full or part rewire? Learn the key differences, when each is required, and what’s best for safety and compliance.
Full vs. Part Rewire Hertford | How to Choose the Right Option
When it comes to updating your home’s electrical system, one of the most common questions Hertford homeowners ask is: Do I need a full rewire, or will a part rewire be enough?
The answer depends on the age, condition, and safety of your current wiring — and sometimes on your future renovation plans. Choosing the right option isn’t just about cost; it’s about keeping your home safe, compliant, and ready to handle the demands of modern living.
This guide will help you understand the differences between a full and part rewire, when each is necessary, and what’s involved in the process.
1. What is a Full Rewire?
A full rewire replaces all of the electrical wiring in your property. This includes:
- New cabling throughout the home.
- Replacement of all switches, sockets, and light fittings.
- A new consumer unit with modern circuit protection.
- Updated earthing and bonding to current regulations.
When you might need a full rewire:
- Your home is over 30 years old and hasn’t been rewired.
- The wiring is unsafe or fails an Electrical Installation Condition Report (EICR).
- You’re doing major renovations or extensions.
2. What is a Part Rewire?
A part rewire updates only certain circuits or sections of your home’s wiring. This could involve:
- Rewiring a single room (such as a kitchen or extension).
- Updating old lighting circuits.
- Replacing wiring damaged by wear, pests, or water ingress.
When you might need a part rewire:
- Most of your wiring is in good condition, but some circuits are outdated.
- You’re refurbishing part of your home and want it brought up to standard.
- You need to add new electrical capacity in certain areas.
3. How to Decide Which You Need
The best way to determine whether you need a full or part rewire is with a professional inspection. A qualified electrician will:
- Test your circuits for safety.
- Check wiring insulation condition.
- Assess compliance with the latest wiring regulations (BS 7671).
- Advise on the most cost-effective, future-proof option.
4. The Pros and Cons of a Full Rewire
Pros:
- Brings the whole property up to current safety standards.
- Provides peace of mind for years to come.
- Increases property value and marketability.
- Allows for modern electrical demands.
Cons:
- More expensive than a part rewire.
- More disruptive to your home (though we minimise mess).
5. The Pros and Cons of a Part Rewire
Pros:
- Less costly than a full rewire.
- Less disruptive.
- Ideal for targeted upgrades.
Cons:
- Older wiring elsewhere in the property may still cause issues later.
- May require future rewiring if other circuits deteriorate.
6. What’s Involved in the Process?
Whether you choose a full or part rewire, the process generally includes:
1. Initial Survey – Detailed inspection of your wiring.
2. Quotation – Clear, no-hidden-fees pricing.
3. First Fix – Running new cabling before plastering or decorating.
4. Second Fix – Installing switches, sockets, and fittings.
5. Testing & Certification – Ensuring everything meets safety standards.
7. How Long Will it Take?
- Full Rewire – Typically 5–10 days for a 3-bedroom house in Hertford.
- Part Rewire – Often completed in 1–3 days, depending on the scope.
8. Safety and Legal Requirements
Rewiring is notifiable work under Part P of the Building Regulations, which means it must be carried out by a qualified, registered electrician. This ensures the work is safe, certified, and compliant with UK law.
