What our clients say
"ARZ Construction built our rear extension and the result is stunning. From the first visit right through to handover, the team were professional, tidy and kept us informed every step of the way. The finish is exactly what we asked for. Would not hesitate to recommend."

"We had a dormer loft conversion done and the whole process was smooth. Very competitive price and the quality of the work is excellent. Our project manager was on site regularly and always available on the phone. The new bedroom and en-suite look brilliant."

Frequently Asked Questions

Do you provide Part P certification for electrical work in Croydon?
Yes. All notifiable electrical work we carry out is certified under Part P of the Building Regulations. You receive an Electrical Installation Certificate and, where required, notification to Croydon Building Control.
How much does a full house rewire cost in South London?
A full rewire for a typical three-bedroom house in South London ranges from £4,500 to £7,500 depending on the number of circuits, property age and access. We provide a detailed scope and fixed price before any work begins.
How long does a rewire take?
A full rewire on a 3-bed house typically takes 5–7 days. Larger properties or those requiring remedial making-good can take 7–10 days. We keep disruption to a minimum and leave the site clean at the end of each day.
Can you install an EV charging point at my Croydon home?
Yes. We install home EV charging points from all major brands and handle the OZEV grant paperwork where applicable. Installation is typically completed in a single day.
Do I need an EICR before selling my property?
An Electrical Installation Condition Report (EICR) is not legally required for a standard sale, but many buyers and mortgage lenders now ask for one. We carry out EICR inspections and any remedial work required to achieve a satisfactory report.
