If you are replacing an old fuse box or upgrading a dated consumer unit, the short answer is this: the cost to replace a consumer unit in London<\/a> is usually around \u00a3650 to \u00a31,500<\/strong>, with many straightforward jobs landing close to the middle of that range.<\/p>\n

The final price depends on the size of your property, the number of electrical circuits, the condition of your wiring, the type of consumer unit fitted, and whether the electrician finds faults that need putting right before the new board can be safely connected.<\/p>\n

Before you book, it is worth checking current electrician rates for your area on HaMuch, because London labour costs can vary noticeably by borough, parking, access, and availability.<\/p>\n

Typical consumer unit replacement cost in London<\/h2>\n

For a normal London flat or house, a consumer unit replacement is usually priced as a complete job rather than a simple hourly visit. That price normally includes the new board, labour, testing, certification, and basic materials.<\/p>\n

\n\n\n\n\n\n\n\n\n\n
Type of job<\/th>\nTypical London cost<\/th>\n<\/tr>\n<\/thead>\n
Small flat, simple consumer unit swap<\/td>\n\u00a3650 to \u00a3950<\/td>\n<\/tr>\n
Average house or larger flat, standard replacement<\/td>\n\u00a3800 to \u00a31,300<\/td>\n<\/tr>\n
Larger home with more circuits<\/td>\n\u00a31,200 to \u00a31,800+<\/td>\n<\/tr>\n
Replacement plus fault-finding or remedial work<\/td>\n\u00a31,500 to \u00a32,500+<\/td>\n<\/tr>\n
Emergency or out-of-hours replacement<\/td>\nOften higher, quote required<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

These are realistic guide prices, not a guaranteed fixed fee. A low quote may be perfectly valid for a simple job, but it should still include proper testing and certification. If it only covers \u201cswapping the box\u201d with no mention of inspection, certificates, or Building Regulations notification, ask more questions before agreeing.<\/p>\n

What is a consumer unit, and why replace it?<\/h2>\n

A consumer unit is the modern name for the electrical fuse box that distributes electricity around your home. It contains switches and protective devices that help shut off power if there is a fault.<\/p>\n

You might need a replacement if your current unit is old, damaged, overloaded, lacks modern safety protection, or has been flagged during an electrical inspection. In London, this is common in older flats, Victorian terraces, converted buildings, and rental properties that have had electrical additions over many years.<\/p>\n

A new consumer unit can improve the safety and usability of your electrical system, but it is not a cosmetic upgrade. It is controlled electrical work that needs to be tested properly by a qualified electrician.<\/p>\n

What should be included in the quote?<\/h2>\n

A proper consumer unit replacement quote should be more than a price for the plastic or metal box on the wall. Most of the value is in the electrician\u2019s skill, testing, and responsibility for making sure the installation is safe.<\/p>\n

A good quote will normally include:<\/p>\n
