Rewiring your home is one of the most important electrical upgrades you can make. Whether you’re renovating an older property or upgrading outdated wiring, understanding the process can help you plan properly and avoid surprises.
At Wiredd, we carry out house rewires across Belfast every week — so here’s a clear, honest guide on what to expect.
🔍 Why Homes in Belfast Often Need Rewiring
Many properties in Belfast, especially older homes, still have outdated wiring systems that may not meet modern safety standards.
Common reasons for rewiring include:
- Old or unsafe wiring (20–30+ years old)
- Renovations or extensions
- Not enough sockets for modern living
- Frequent electrical faults or tripping
- Upgrading to a modern consumer unit
If your home hasn’t been updated in decades, a rewire is often the safest long-term solution.
🧰 Step-by-Step: The House Rewire Process
Here’s how a typical rewire works:
1. Initial Inspection & Quote
We assess your property, check existing wiring, and discuss your needs — including socket locations, lighting, and any future upgrades (like EV chargers).
You’ll receive a clear quote with no hidden costs.
2. Planning & Preparation
Before work begins, we help you plan:
- Socket and switch locations
- Lighting design
- Internet / TV / smart home needs
👉 Tip: Think ahead — it’s much cheaper to add things during a rewire than later.
3. First Fix (Wiring Installation)
This is the main stage where we:
- Remove old wiring
- Install new cables throughout the property
- Fit back boxes for sockets and switches
⚠️ This stage can be disruptive, as floors and walls may need to be opened.
4. Second Fix (Final Install)
Once plastering is complete, we return to:
- Fit sockets, switches, and lights
- Install the consumer unit (fuse board)
- Connect all circuits
5. Testing & Certification
Every rewire is fully tested and certified to meet UK regulations (BS 7671).
You’ll receive certification for safety and compliance.
🏡 How to Prepare for a House Rewire
Preparation makes a huge difference.
Here’s how to get ready:
✔️ Clear rooms and access points
Move furniture away from walls and ensure easy access for electricians.
✔️ Plan to be without power
You may be without electricity for parts of the job — especially during key stages.
✔️ Consider moving out (if full rewire)
For full rewires, many homeowners choose to stay elsewhere temporarily due to dust and disruption.
✔️ Coordinate with other trades
If you’re renovating, timing is key — rewiring should happen before plastering and decorating.
⏱️ How Long Does a Rewire Take?
Typical timelines:
- 2-bed house: 3–5 days
- 3-bed house: 5–7 days
- Larger homes: 1–2 weeks
This can vary depending on property condition and access.
💰 How Much Does a House Rewire Cost in Belfast?

- 2-bed house: £2,500 – £3,500
