Whether you’re hiring an electrician for a small repair, a full rewire, or a major installation like a garden office or consumer unit upgrade, it’s essential to ask the right questions before agreeing to any work. Electrical work is not just about convenience—it’s about safety, compliance, and long-term reliability.
In this guide, we’ll cover the key questions you should ask your electrician to ensure you hire a qualified, competent professional who will complete the job safely and to the highest standard.
1. Are You a Qualified and Registered Electrician?
Not all electricians are the same. In the UK, qualified electricians should be registered with an approved industry body such as:
- NICEIC (National Inspection Council for Electrical Installation Contracting)
- NAPIT (National Association of Professional Inspectors and Testers)
- ELECSA (Electrical Contractors’ Association Scheme)
Why This Matters:
- Registered electricians follow strict safety standards (BS 7671 Wiring Regulations).
- They are regularly assessed to ensure they are competent and up to date.
- Hiring an unqualified electrician could result in unsafe installations or legal issues.
Follow-up Question: Can you provide proof of your registration and qualifications?
2. Do You Have Public Liability Insurance?
Any electrician you hire should have public liability insurance, which protects you and your property in case something goes wrong.
Why This Matters:
- If an electrician damages your property or causes injury, insurance covers the costs.
- It’s a legal requirement for professional electricians to have adequate insurance.
Follow-up Question: What level of insurance do you have? (Most reputable electricians will have at least £2 million cover).
3. Will the Work Be Compliant with Part P of the Building Regulations?
In the UK, Part P of the Building Regulations states that certain electrical work in homes must be carried out by a qualified electrician and notified to the local authority.
This applies to:
- Consumer unit (fuse box) upgrades
- New circuit installations
- Electrical work in bathrooms and kitchens
- Outdoor electrics (e.g., garden offices, sheds, hot tubs)
Why This Matters:
- If work is not Part P compliant, it may not be legal.
- It could cause issues when selling your property if you can’t provide an Electrical Installation Certificate (EIC).
Follow-up Question: Will you provide the necessary certificates for Building Control approval?
4. Can You Provide an Estimate or Written Quote?
Before starting any electrical work, always ask for a detailed written quote. This should include:
- Labour costs
- Materials (if applicable)
- Potential extra charges
- Timeframe for completion
Why This Matters:
- A written quote ensures clarity and transparency, avoiding unexpected costs.
- It helps you compare different electricians to get the best service at the right price.
Follow-up Question: Does this quote include VAT, or are there any additional costs I should be aware of?
5. Will You Provide an Electrical Installation Certificate (EIC) or Minor Works Certificate?
For any significant electrical work, the electrician should provide a certificate upon completion.
- Electrical Installation Certificate (EIC) – Issued for major work such as new circuits, consumer unit upgrades, or full rewires.
- Minor Electrical Installation Works Certificate (MEIWC) – Given for small jobs like adding a new socket or light fitting.
Why This Matters:
- You need these certificates for home insurance and property resale.
- Without a certificate, you have no proof that the work was carried out safely.
Follow-up Question: When can I expect to receive the certificate after work is completed?
6. How Long Will the Work Take?
It’s important to understand how long the job will take so you can plan accordingly. Some jobs, like replacing a socket, take minutes, while a full rewire could take several days or weeks.
Why This Matters:
- You’ll know what to expect and can make arrangements if power needs to be turned off.
- If an electrician rushes the job, it may compromise safety.
Follow-up Question: Will you keep me updated if there are any delays or additional work required?
7. What Safety Measures Will You Take?
A good electrician will prioritise safety throughout the job. Ask them how they plan to:
- Isolate power safely before starting work.
- Protect your home and family (e.g., using dust sheets, securing tools).
- Test the installation before restoring power.
Why This Matters:
- Prevents electric shocks, fires, and property damage.
- Ensures the work area remains tidy and safe during the project.
Follow-up Question: Do you carry out full safety testing and inspections after the work is completed?
8. Do You Offer a Warranty or Guarantee on Your Work?
A professional electrician should guarantee their work, meaning they will fix any issues that arise due to poor workmanship or faulty materials.
Why This Matters:
- Provides peace of mind that the work is reliable and long-lasting.
- Ensures that if something goes wrong, you won’t be left with extra repair costs.
Follow-up Question: How long does your warranty last, and what does it cover?
9. Can You Recommend Energy-Efficient Solutions?
With rising energy costs, it’s worth asking your electrician for energy-saving recommendations such as:
- LED lighting instead of halogen bulbs.
- Smart thermostats to control heating efficiently.
- Motion sensors for lighting to reduce energy waste.
Why This Matters:
- Reduces your energy bills.
- Helps make your home more eco-friendly.
Follow-up Question: Are there any smart home solutions that would benefit my electrical setup?
10. Can You Provide References or Reviews from Past Clients?
A reputable electrician should be able to provide:
- Customer testimonials.
- Google or Checkatrade reviews.
- Examples of previous work (photos or case studies).
Why This Matters:
- Ensures they have a good track record of satisfied customers.
- Helps you avoid unreliable or inexperienced electricians.
Follow-up Question: Do you have a website or social media where I can see reviews and examples of your work?
