NICEIC-approved electricians upgrading fuse boards and consumer units across Edenbridge's period High Street properties, village homes, and farms throughout the Eden Valley. Safe, compliant, and built to the latest 18th Edition standards.

McMillan Electrical has been upgrading consumer units and replacing fuse boards across Edenbridge for nearly two decades. Edenbridge sits on the River Eden in the Kent countryside, close to the Surrey and Sussex borders — and its electrics reflect that setting: medieval and Georgian buildings in the town centre, twentieth-century estates around them, and a wide scatter of farms, stables, barns and converted outbuildings beyond, many on long supply runs and overhead lines.
Whatever the property, our NICEIC-approved team makes sure your installation meets current 18th Edition standards.
A consumer unit upgrade replaces your existing fuse box with a new, fully 18th Edition compliant board — fitted with individual RCBO protection on every circuit and a Type 2 Surge Protection Device. The result is a safer installation that protects your circuits independently, so if one trips, the rest of your property stays live.
Most upgrades are completed in a single day. We isolate your supply, fit the new board, test every circuit, and issue your Electrical Installation Certificate before we leave — your legal proof of compliance under Part P of the Building Regulations. We handle every step from the initial assessment through to certification, including properties with outbuildings, workshops or stable blocks running off the main supply.



Edenbridge’s High Street holds a run of medieval and timber-framed buildings — including the fourteenth-century property that houses the Eden Valley Museum — alongside Georgian and Victorian frontages, most with flats and offices above the shops. Boards in buildings of this age have usually been fitted wherever space allowed and added to repeatedly, and many still have no RCD protection at all. The twentieth-century housing around Marlpit Hill, Stangrove and Spitals Cross makes up much of the rest of the town, and those boards are increasingly falling short of current 18th Edition standards.
It’s beyond the town that Edenbridge differs most from its neighbours. The surrounding farms, smallholdings, equestrian yards and converted barns typically run multiple buildings off one original supply, with sub-boards and circuits added as outbuildings changed use — a workshop here, a stable block there, a garden office in a converted store. These installations benefit enormously from a full assessment rather than a board swap. Rural properties across the Eden Valley are also commonly fed by overhead supplies, which makes a Surge Protection Device particularly worthwhile given the exposure to lightning-induced voltage spikes. And on the low ground near the river, where flooding has been a recurring issue for the town, board position and the condition of low-level circuits are worth checking properly rather than assuming.
Consumer unit upgrades in Edenbridge start from £700 + VAT (£840 inc VAT) for a standard domestic property, rising from £1,000 + VAT (£1,200 inc VAT) for larger or more complex installations. Every upgrade is the same full specification — an 18th Edition compliant board with individual RCBO protection on every circuit, a Type 2 Surge Protection Device, and a full EICR on your installation, so you get a written assessment of the whole property alongside the new board.
A dedicated sub-board for a garage, workshop, stable block or outbuilding runs from £250 to £450 + VAT (£300 to £540 inc VAT), whether it’s fitted alongside a main board upgrade or as a standalone job.

Everything you need to know about consumer unit upgrades across Edenbridge
and the surrounding areas.
Yes. As well as Edenbridge itself, we regularly carry out consumer unit upgrades in Four Elms, Hever, Chiddingstone, Cowden, Crockham Hill, Marsh Green, Markbeech, and Bough Beech.
Yes, and it’s one of the more common jobs we carry out around Edenbridge. A dedicated sub-board separates your outbuilding supply from the main house circuits, protecting both, and gives you proper capacity for lighting, power and specialist equipment. We make sure the cable run from the main board is correctly rated for the distance and load, and fit an IP-rated unit where the environment needs one. All work is fully certified.
It can. Board position, the height of low-level circuits, and the condition of anything that has previously been exposed to water are all worth assessing properly. The full EICR included with every upgrade covers your whole installation, not just the new board, so you get a written picture of where things stand — and where a board can practically be repositioned as part of the work, we’ll tell you.
Yes. Properties fed by overhead supplies are more susceptible to lightning-induced voltage spikes than those on underground feeds, which makes a Type 2 Surge Protection Device particularly valuable. We include SPD as standard in all our consumer unit upgrades.
One of the longest high streets in Kent, running north to south through the town with a run of medieval timber-framed buildings at its southern end — among them the fourteenth-century hall house that now holds the Eden Valley Museum, and the old inn whose gallows sign still spans the road. Independent shops, pubs and flats above them make up most of the frontage.
North of the town centre towards Edenbridge station, largely twentieth-century housing built as the town grew along the railway. Semis, terraces and bungalows on established residential streets, with the open countryside starting almost immediately beyond them.
Edenbridge’s post-war residential areas, built out through the 1950s, 60s and 70s on the eastern side of the town. A mix of family housing, flats and maisonettes close to the schools, the recreation ground and the town’s sports facilities.
The villages north and east of Edenbridge, in some of the best-known countryside in west Kent — Hever Castle and its lake, Chiddingstone’s National Trust village street, and the lanes between them. Housing here is mostly older cottages, farmhouses and converted agricultural buildings, with later infill around the village centres.
West towards the greensand ridge and Chartwell, and south towards the Sussex border, the land is given over to farms, smallholdings and equestrian yards. Properties are scattered, often set well back on private drives, and frequently take in oast houses, barns and outbuildings converted over the years.
We’re proud to help keep Edenbridge’s homes, farms and businesses — from the oldest buildings on the High Street to the newest conversions out in the valley — safe, compliant, and properly protected.
