House Rewiring in Hertfordshire

Trusted Electrical Specialists with Over 40 Years of Experience

If your property has outdated wiring, an old fuse board or recurring electrical faults, a full house rewire could be the safest and most cost-effective solution.

DB Sharp & Sons are NICEIC-approved electricians carrying out full and partial house rewires across Hertfordshire, including Letchworth, Hitchin, Stevenage, Welwyn, Baldock and surrounding areas.

With over 40 years of experience, we deliver safe, compliant rewiring work to current UK standards — with minimal disruption to your home.

What Does a House Rewire Involve?

A full house rewire replaces all the electrical wiring throughout your property. This includes new cabling, sockets, switches, lighting circuits and a modern consumer unit.

Rewiring brings your home up to current UK wiring regulations (BS 7671) and gives your electrical system the capacity to handle modern appliances, smart technology and increased power demands.

Older properties, particularly those built before the 1970s — often contain rubber or fabric-insulated wiring that is no longer safe or suitable for today’s usage. A rewire removes that risk entirely.

Signs Your Home May Need Rewiring

You may need a full or partial rewire if you notice:

Not sure whether you need a full rewire or something smaller? We can carry out an electrical inspection and give you an honest assessment — we will never recommend more work than is needed. We also offer EICR inspections if you simply need your current wiring assessed.

Partial Rewires and Electrical Upgrades

Not every property requires a full rewire. In some cases, a partial rewire, consumer unit upgrade or additional circuit installation may be all that is needed.

We assess the condition of your current wiring and give you straightforward advice based on your property and your future plans — whether you are renovating, extending or simply bringing things up to standard.

House rewire costs vary depending on the size of your property and the scope of work involved. We provide free, no-obligation quotes following an in-person assessment so you know exactly what is involved before any work begins.

Our House Rewire Process

Rewiring your home is a significant project. We keep the process organised, transparent and as disruption-free as possible.

1. Initial consultation and property assessment

We visit your property, assess the existing wiring and discuss your requirements in full.

2. Clear written quotation

You receive a detailed quote covering scope of work, timescales and costs — no hidden extras.

3. First fix

Our electricians run new cables through the property and prepare all circuits. Most of this work happens within walls, floors and ceilings.

4. Second fix

Sockets, switches, lighting and the new consumer unit are fitted and connected.

5. Testing and certification

All work is fully tested on completion and certified to confirm compliance with BS 7671. You receive your electrical installation certificate as part of the handover.

A typical house rewire for a three-bedroom property takes between five and ten days depending on access and complexity. We will give you a clear timeframe before work begins.

Testimonials

'I cannot praise DB Sharp and Sons highly enough. They completed a big project for us, a double-storey extension and reconfiguring most of the house, as well as rewiring and replumbing the whole house. All the work was carried out to a great standard by friendly and trustworthy people. The site was always kept clean, even though we weren't living in it and we were always kept informed of progress. Our six-month-long project was made enjoyable due to their professionalism and great workmanship. I would not hesitate to use them again.

A.L. Herts

'I can't recommend DB Sharp and team more highly. They renovated and added a double-storey extension to our house. The house was completely refurbished - new roof, windows and doors, electrics and plumbing. The team carried our the work on our 1926 home in a very sympathetic manner, even making suggestions for small touches which have added a lot to our overall finish. I found the guys working for DB Sharp extremely trustworthy, reliable and friendly. The work was carried out in the agreed timescale and to an extremely high standard. Communication with the team was great and there were no hidden extras when it came to the bill. I am very happy to recommend DB Sharp to anyone taking on any scale of building work. You will not regret it.'

Frequently Asked Questions

Q: How much does a house rewire cost in Hertfordshire?

The cost of rewiring a house depends on the property’s size, age, accessibility and the number of sockets, lighting points and circuits required. Whether the property is occupied and the amount of making good needed can also affect the price.

DB Sharp & Sons provides a free property assessment followed by a detailed, no-obligation quotation covering the agreed work, estimated timescale, testing and certification. Contact our team to arrange your rewiring assessment.

Q: How long does a house rewire take?

A full rewire on a three-bedroom property typically takes between five and ten days. Larger properties or those with more complex wiring may take longer. We will give you a clear timeframe in your quotation before work starts.

Q: Do I need to move out during a rewire?

Not always. For smaller properties or partial rewires, many homeowners stay in the property throughout. For a full rewire on a larger home, it can be more practical to vacate temporarily. We will discuss this with you during the initial assessment and plan the work to minimise disruption wherever possible.

Q: Is a house rewire covered by insurance?

Most standard home insurance policies do not cover the cost of rewiring as it is considered maintenance work rather than accidental damage. However, having up-to-date wiring can reduce your premiums and some insurers require evidence of safe wiring for older properties. We recommend checking with your insurer directly.

Q: Will my walls need to be replastered after a rewire?

Some minor plastering or filling will be needed where cables have been chased into walls. We work as cleanly as possible and leave surfaces ready for decoration. We will make clear what redecoration is likely to be needed before work begins.

Q: Do you provide certification after a rewire?

Yes. All rewiring work is fully tested on completion and you receive an Electrical Installation Certificate confirming compliance with BS 7671. This is required by law and will be needed if you sell the property.

Q: How do I know if my home needs rewiring?

Common signs include flickering lights, frequent circuit breaker trips, old-style fuse boards, burning smells from sockets and rubber or fabric-insulated wiring. If you are unsure, we can carry out an EICR inspection and give you an honest assessment of your wiring.

Q: Are you NICEIC approved?

Yes. DB Sharp & Sons are NICEIC-approved electrical contractors. This means our work is independently assessed against the UK’s highest electrical standards. All rewiring work is carried out by qualified electricians and certified on completion.
