- Old-style fuse board with ceramic fuse wire rather than modern RCDs or RCBOs
- Frequently tripping circuit breakers that won't reset, or circuits that trip for no obvious reason
- Persistent flickering lights across multiple rooms in the property
- Burning smell or scorch marks around sockets, switches or the consumer unit
- Sockets or switches that feel warm, buzz or vibrate to the touch
- EICR inspection has returned C1 (danger present) or C2 (potentially dangerous) observations
- Planning a kitchen, bathroom, extension, loft conversion or major renovation
- Property has been flagged by an insurer, letting agent or solicitor as requiring electrical inspection
House Rewiring Cardiff — Frequently Asked Questions
How long does a full house rewire take in Cardiff?
For a typical 3-bed Cardiff terrace or semi, a full rewire takes 3–5 working days. A 2-bed flat can often be completed in 2–3 days. Larger properties, homes with complex layouts, or those requiring significant cable routing through solid walls may take up to 7–10 days. We work room by room where possible to minimise disruption, and ensure you have working power at the end of each day. We’ll give you a realistic and honest timeline when we survey the property — not a figure designed to win the job.
Do I need to move out during a rewire?
Not necessarily. For most occupied Cardiff properties we work progressively through the house, room by room, ensuring you have access to power, heating and essential facilities each evening. For smaller properties or those being fully renovated at the same time, it can be more practical and less stressful to vacate for the duration — we’ll advise honestly on this when we survey your property so you can plan ahead. We never ask you to vacate unnecessarily.
How much does a house rewire cost in Cardiff?
Rewire costs in Cardiff vary depending on the size of the property, number of rooms and circuits, condition of the existing wiring and whether a consumer unit upgrade is included. As a guide: a 2-bed Cardiff flat or terrace typically starts from £2,500; a 3-bed terrace from £3,500; a 4-bed property from £4,500 upwards. Partial rewires and consumer unit upgrades start from around £1,000. These are starting figures — every property is different and we always survey before quoting. We provide a clear, itemised written quote after the free survey with no hidden costs and a fixed price, not an estimate.
What certificate do I get after a rewire?
You’ll receive an Electrical Installation Certificate (EIC) — the required document confirming the rewire was carried out to BS7671 18th Edition standards by a NICEIC-approved contractor. The EIC is essential if you plan to sell the property, let it to tenants, remortgage or insure it. Your solicitor, estate agent, letting agent and insurer may all ask for it. Keep the original certificate somewhere safe — we recommend also notifying your local authority building control, which we can advise on.
Do you rewire HMOs and rental properties in Cardiff?
Yes — HMO and landlord rewires are a significant part of our Cardiff work. We carry out full and partial rewires for HMOs, student lets, terraced rental properties and landlord portfolios across Cardiff. Our NICEIC-certified rewires meet the requirements of the Renting Homes (Wales) Act 2022 and come with the Electrical Installation Certificate your EICR inspector and letting agent will need. We understand the pressure of void periods and work efficiently. Portfolio landlords with multiple properties are welcome to discuss scheduled inspection and rewire programmes.
Will I need to redecorate after a rewire?
Yes, some making good will be required where cables have been chased into walls and ceilings. The extent of this depends on the property type — solid-wall Victorian terraces typically require more making good than cavity-wall properties, as cables often need to be chased directly into plaster. Our team leaves all chases neat, filled flush and ready for plastering or painting. We are clear about the making-good requirements before we start so there are no surprises, and we never leave the property with open channels or rough edges.
