How long does a rewire take?
A full rewire for an average 3-bedroom home usually takes 5–10 working days, depending on the property size and access. Partial rewires are often quicker.

Do I need to move out during a rewire?
Not always. We can phase the work so you can stay at home, but some customers choose to move out for comfort during a full rewire because of the dust and disruption.

Will you need to damage walls and ceilings?
Yes, some chasing and lifting of floorboards is normally required. We keep this to a minimum and always agree routes with you in advance. Making good (plastering/painting) can be arranged separately if needed.

Do you provide certification?
Absolutely. Every rewire is fully tested and comes with an NICEIC Electrical Installation Certificate (EIC) for your records and peace of mind.

Can you upgrade my consumer unit at the same time?
Yes. Most rewires include a new consumer unit with RCBOs and SPD to meet the latest safety standards. We’ll confirm this during your survey.

The cost of a rewire depends on the size of your property, the specification (standard white fittings vs. decorative or smart), and whether it’s a full or partial rewire. To give you a rough idea:

• 1–2 bedroom flat: from £3,000 – £5,000
• 3 bedroom house: from £5,500 – £8,000
• 4–5 bedroom house: from £8,500 – £12,000+

(Prices are typical for London & Hertfordshire and include labour, standard materials, and certification. Decorative accessories, plastering/decoration, or smart control systems are usually additional.)
