consumer unit installation

Question

what is the cost to install anew consumer unit, transfer the main supply and do the part P testing and sign off?

Alan · Accepted Answer

The overall price would vary depending on the number of circuits in the consumer unit and whether any wiring faults become apparent before or after the upgrade. New consumer units generally contain more stringent fault detection that can capture more faults than older units.
A full EICR (Electrical Installation Condition Report) would be required post-installation of the new consumer unit. This activity covers the Part P you mention and the local authority building control may need to be notified of the work and the competence of those carrying out the work

If "transfer of the main supply" just means reconnection of the main supply tails from the meter, then that would all be included in the price of the installation/upgrade.

As a guide and depending on location and complexity, price for the entire works required could be in the region of £500 - £750.

Small flats (around 6–8 circuits) — £350–£550

Average 2–3 bed houses — £450–£800

Larger homes or higher spec units (all RCBO, surge protection etc.) — £800–£1,200+

A lot of general guides also say a typical consumer unit replacement in the UK (including labour, testing, certification and Building Control notification under Part P) usually falls somewhere around £450–£900.

I’m in London / South East, and I know labour and materials tend to be higher here. I’ve seen ballpark figures like:

Smaller installs — £450–£700

Standard 8–10 way boards — £650–£950

Larger or premium spec installs — £900–£1,300+

Hi Jean, the cost would depend upon the number of circuits and location of the consumer unit. Assuming the new unit could fit in the same cabinet as the old one and no new circuits needed running then materials cost would be £100-150 and labour £300-400. You would need to hire a certified electrician who is able to sign off the work.

For a standard domestic consumer unit change, including transferring all existing circuits, full testing, certification, and Part P Building Control notification, most homeowners should expect:

Typical cost: £450–£750 + VAT

This usually includes:

Supply of a modern metal consumer unit (RCBO or dual-RCD configuration)

Safe isolation and transfer of all circuits

Full electrical testing to BS 7671

Electrical Installation Certificate

Part P notification to Building Control

The final price can vary depending on access, number of circuits, condition of existing wiring, and whether any remedial work is required (e.g. upgrading bonding or correcting faults found during testing). A site visit is the only way to give a fixed, accurate quote.
