What Does a Full House Rewire Actually Involve?
A full house rewire means completely replacing all the electrical wiring throughout your home. That includes your consumer unit (fuse board), circuits, cables, sockets, light fittings, and all the connections in between.
It’s not a quick patch job. It’s a thorough, systematic installation that makes sure every inch of your home’s electrics meets current regulations and is safe for modern use.
Most rewires happen in two stages. First, a first fix where the cables are run through walls, floors, and ceilings. Then a second fix where everything is connected up, tested, and certified.
Most people don’t realise that their electrics are outdated, but it can be life-saving. Old wiring systems simply weren’t built to handle the electrical demands of modern living, from EV chargers to smart home tech to multiple high-draw appliances running at once.
Full House Rewire Cost in Wiltshire: What to Budget in 2026
Prices vary depending on the size of your property, how accessible the wiring routes are, and the age and condition of your existing installation. Here’s a realistic breakdown for Wiltshire homeowners in 2026.
| Property Size | Estimated Cost Range (2026) | Typical Duration |
|---|---|---|
| 1-2 bedroom flat or cottage | £3,000 – £5,500 | 3 – 5 days |
| 3 bedroom semi or terrace | £5,000 – £8,500 | 5 – 7 days |
| 4 bedroom detached | £7,500 – £12,000 | 7 – 10 days |

5 Key Cost Factors in Your Full House Rewire for Wiltshire Homes
No two rewires are the same. Knowing what drives the cost up or down helps you plan your budget properly and have a more informed conversation with your electrician.
At-a-glance breakdown of the five main cost factors in a Wiltshire full-house rewire. Use this guide to budget wisely and compare quotes.
- Property size: More rooms means more circuits, more cable, and more labour time. It’s as simple as that.
- Property age and construction type: Older or period properties with lath and plaster walls, conduit piping, or decorative cornices require more careful, skilled work and take longer to complete.
- Whether the property is occupied: An empty property is typically 10% to 20% cheaper to rewire because there’s less risk of disruption and more freedom to work quickly.
- The scope of additional upgrades: Adding smart home features, EV charging points, or extra sockets and circuits will add to the overall cost.
- Access and location: Rural Wiltshire properties can sometimes involve longer travel time and more complex access routes, which your electrician should factor into their quote honestly.
It takes experience and forward-thinking to provide bespoke electrical solutions suited to modern living and working with various properties. That’s what we bring to every rewire we carry out across Wiltshire.
Older Properties in Wiltshire: Why Your Full House Rewire Cost Could Be Higher
Wiltshire is full of beautiful older homes. Thatched cottages, Georgian townhouses, Victorian terraces — they all have incredible character and charm. But rewiring them is a different challenge compared to a modern new-build.
Lath and plaster walls and ceilings, conduit piping, thatches, and decorative cornices require experience and mean working with delicacy and consideration. You can’t just chase out a plaster wall without knowing what’s behind it.
This can make installs a challenge for the less experienced, but not us. We specialise in rewiring older and period properties right across Wiltshire, and we know exactly how to work with the fabric of your home rather than against it.
If your property has original features you want to protect, that matters to us too. We’ll always discuss the approach with you before we start and keep disruption to an absolute minimum.
For more on this, take a look at our expert guide to house rewiring solutions for older properties — it covers the specific challenges and how to approach them properly. For the latest guidance on the best complete house rewiring solutions for older properties, including techniques for protecting original features, we’ve published a comprehensive updated guide for 2026.
How Long Does a Full House Rewire Take?
The timeframe for a full 3-bedroom house rewire typically spans 5 to 10 working days. Larger or more complex homes naturally take longer.
We know downtime in your home is a hassle. That’s why we work efficiently and with purpose, aiming to save you up to half the time compared to less organised teams while keeping the same high quality throughout.
During the rewire, some rooms may be inaccessible at different points. We’ll always walk you through the schedule in advance so you know what to expect each day.
For landlords in particular, minimising void periods is critical. We work hard to keep timescales tight and get your property back to being tenantable as quickly as possible.
Warning Signs You Need a Full House Rewire Now
Some warning signs are easy to miss. Others are impossible to ignore but get dismissed as “just one of those things”. Either way, ignoring them is a real risk.
Here’s what to look out for:
- Flickering or dimming lights that aren’t linked to a bulb issue
- Buzzing or crackling sounds from sockets or switches
- Fuses or circuit breakers that trip regularly without explanation
- Scorch marks or burning smells around outlets
- Old rubber-coated or fabric-covered wiring (common in pre-1960s homes)
- A fuse board with old-style fuse wire instead of modern circuit breakers
- Sockets that feel warm to the touch even when nothing is plugged in
Fault finding and rewiring are vital for electrical safety in your home or office. If any of the above sounds familiar, get in touch with us today — don’t wait until it becomes an emergency.
EICR and Your Full House Rewire Cost in Wiltshire: What You Need to Know
An Electrical Installation Condition Report (EICR) is essentially a health check for your home’s wiring. It identifies any areas that don’t meet current standards and flags anything that’s potentially unsafe.
If your existing wiring fails an EICR, a full rewire is often the recommended remedy. And once your rewire is complete, a new EICR is issued as part of the sign-off process.
For landlords, an EICR is a legal requirement — you need a valid certificate in place for all rented properties. Our ultimate guide to landlord electrical safety certificates covers everything you need to know about that process in 2026.
We’re NICEIC-registered, which means our EICR certificates are recognised by all local authorities and letting agents across Wiltshire. That’s not something every electrician can say.
Why Choose a NICEIC-Certified Wiltshire Electrician for Your Rewire?
Choosing the right electrician for a full house rewire isn’t just about price. It’s about trust, safety, and making sure the work is done to a standard that will stand up to scrutiny now and for years to come.
Here’s why NICEIC certification matters so much on a job like this:
- Your work is fully guaranteed and backed by nationally recognised standards
- You receive proper certification that’s accepted by insurers, mortgage lenders, and local authorities
- You have recourse if anything isn’t up to standard (something that isn’t always the case with unregistered traders)
- It proves the electrician has been independently assessed and approved to carry out notifiable electrical work
Here at Greener Electrical, we’ve been trading for over five years and are happy to help with any needs. We’re fully NICEIC-registered, and every rewire we complete comes with fully guaranteed workmanship and the right documentation to give you complete peace of mind.
We cover the whole of Wiltshire, including Marlborough, Swindon, Devizes, Chippenham, Salisbury, Trowbridge, and all the villages and rural areas in between. Wherever you are, you’ll get the same fuss-free, high-quality service.
How to Get the Best Value on Your Wiltshire House Rewire Cost
Getting the best value doesn’t mean going with the cheapest quote. It means getting competitive pricing from a team that will do the job right first time, without hidden extras appearing once work has started.
Here’s how to make sure you’re getting genuine value:
- Always get at least two or three quotes and make sure they’re comparing like for like (same scope of work, same certifications included).
- Ask about scheduling flexibility. Rewiring while the property is empty can reduce your costs by 10% to 20%.
- Discuss add-ons upfront. If you’re thinking about smart home upgrades, an EV charger, or extra sockets, bundle them into the rewire rather than adding them later at a higher cost.
- Check certification is included in the quote. Some cheaper quotes exclude the EICR sign-off, which you’ll then have to pay for separately.
- Confirm the company is NICEIC-registered before agreeing to any work. Fully certified workmanship protects you, simple as that.
We believe in competitive pricing without breaking the bank, and we’re always upfront about costs from the very first conversation. No surprises, no add-ons you didn’t agree to.
If you’re thinking about future-proofing your home at the same time, our complete 2026 guide to upgrading to modern wiring is well worth a read before you book your quote.

Frequently Asked Questions
How much does a full house rewire cost in Wiltshire in 2026?
For most Wiltshire homeowners, a full house rewire costs between £3,000 and £15,000 depending on property size, age, and complexity. A standard 3-bedroom home typically falls in the £5,000 to £8,500 range. Always get a site-specific quote to get an accurate figure for your home.
Is a full house rewire worth it in 2026?
Yes, absolutely. A full house rewire increases your property’s market value by around 3% to 5%, satisfies legal safety obligations, and protects your home from the very real risk of electrical fires caused by outdated wiring. For most Wiltshire homeowners, the return easily justifies the cost.
How long does a full house rewire take in Wiltshire?
A typical 3-bedroom home takes 5 to 10 working days to rewire. Larger properties or older period homes with more complex construction can take up to 15 days or more. Your electrician should give you a clear timeline before work begins.
Do I need to move out during a full house rewire?
You don’t always have to move out, but it’s often easier if you can. An empty property is typically 10% to 20% cheaper to rewire and allows the work to be completed faster. If you stay, the electrician will agree a phased approach with you to keep disruption manageable.
What are the signs that my Wiltshire home needs a full rewire?
Key warning signs include flickering lights, buzzing from sockets, regularly tripping fuses, discoloured or scorched outlets, and visible old rubber or fabric-covered cables. If your home is pre-1970s and hasn’t been rewired since, it’s almost certainly time to have it assessed.
Do I need an EICR before a house rewire in Wiltshire?
An EICR is typically carried out as part of the rewire process rather than separately before it. Once your rewire is complete, your NICEIC-registered electrician will issue a new Electrical Installation Certificate and EICR confirming everything meets current regulations. Landlords in particular need this documentation in place for legal compliance.
How do I find a trusted electrician for a full house rewire in Wiltshire?
Look for a NICEIC-registered, fully certified local electrician with experience in Wiltshire properties, including older and period homes. Check that your quote includes all certification as standard, and always get a no-strings-attached quote before committing. Here at Greener Electrical, we cover the whole of Wiltshire and are happy to help.
