How we replace the unit
We visit the home or premises, open the current unit and test the insulation of each circuit and the earthing. From there we prepare a detailed written quote.
On the day, we cut the supply, fit the new enclosure with its protection devices and connect the circuits one by one, matching each breaker to its cable as the REBT requires.
Before leaving, we test every RCD, label the switches and make good the wall around the unit.

Frequently asked questions
01Can the consumer unit be replaced without rewiring?
Yes, if the wiring is in good condition. We test its insulation first; if any circuit fails, we point it out in the quote so you can decide what to do with it.
02What does a surge protection device do?
It cuts the supply when a voltage spike arrives from the grid or a storm, protecting the fridge, boiler, computer and other connected equipment.
03Will I be without power during the work?
Only while the old unit is disconnected and the new one is connected. We agree the time of the cut with you and leave everything working before we go.
04How much does a complete renovation cost?
There is no single price. The estimate depends on the condition and size of the home, the scope of the project, materials and work required. Tell us your idea so we can assess your specific case.
05How long does a renovation take?
It depends on the type of home, the scope of the work and the project's constraints. Once we have studied the renovation, we can give you a more accurate estimate.
06Can a home be renovated while people still live in it?
It depends on the scope, estimated duration and condition of the home. When we study the project, we will assess whether it is feasible and what precautions or alternatives should be considered.
07How can I request an estimate?
Choose what you want to renovate, tell us whether the work is partial or complete, and leave your name, phone number and email. This lets us provide initial guidance. You can also write to us directly on WhatsApp.
