How Much Does a Consumer Unit Replacement Cost in Surrey?
Consumer unit prices vary widely. Here's what affects the cost, what to expect on the day, and why cheapest is rarely best.
Consumer unit replacement is one of the most common electrical jobs in domestic properties — but prices quoted online vary enormously. Here is an honest breakdown of what affects the cost and what you should expect to pay in Surrey.
What affects the price?
Several factors influence the final cost of a consumer unit replacement:
- ⚡The type of unit — a standard split-load consumer unit with RCD protection costs less than a fully-loaded unit with AFDD (arc fault detection) protection
- ⚡The number of circuits — more circuits means more MCBs and more testing time
- ⚡The condition of the existing installation — if remedial work is needed before the new unit can be installed, this adds to the cost
- ⚡Access to the existing unit — units in awkward locations take longer to work on
- ⚡Whether an EICR is required at the same time
What does a consumer unit replacement include?
A properly quoted consumer unit replacement should include:
- ⚡Supply and installation of the new consumer unit
- ⚡Testing of all circuits
- ⚡An Electrical Installation Certificate
- ⚡Part P notification to your local authority
- ⚡Labelling of all circuits
Why cheapest is rarely best
Consumer unit replacement is notifiable work under Part P of the Building Regulations. An unregistered electrician cannot self-certify this work — which means you may not receive the correct certification, and the work may not be registered with your local authority. This can cause serious problems when you come to sell your property.
What about AFDD protection?
The 18th Edition Wiring Regulations (Amendment 2) introduced requirements for AFDD (arc fault detection device) protection in certain locations. AFDDs detect dangerous arcing faults that RCDs cannot detect. While not yet mandatory in all domestic installations, they are increasingly recommended — particularly in older properties with ageing wiring.
Getting a fair quote
Always get at least two quotes and check that the electrician is NICEIC registered. Ask specifically what is included — particularly whether the Electrical Installation Certificate and Part P notification are included in the price.
