Consumer unit replacement in Frome

Changing the board in an older Frome house

In a modern house the consumer unit goes in the hall cupboard and nobody thinks about it again. In a lot of Frome houses it is not that simple. The meter may be in a cellar, a lobby or an outside box set into a stone wall. The existing board may be fixed to panelling or a wall that matters. The tails from the meter may run across a historic surface.

So we start by agreeing where the new board should go. Sometimes that is the same spot. Sometimes it is a short move to a cupboard, a cellar wall or a utility room where it can be reached easily and seen properly, with the tails run discreetly. In a listed building we avoid fixings into historic fabric where there is any alternative.

The board itself is always the same type: a metal consumer unit with a double-pole main switch and a Type A RCBO on every circuit. No split-load, no shared RCDs. Each circuit is protected on its own, so a fault in one room does not plunge the whole house into darkness.

From Trinity cottages to new builds

The restored houses in the Trinity area and the older streets around the centre often have boards fitted during renovations in the 1980s and 1990s. Those are now old enough to lack RCD protection on some circuits, and many have rewireable fuses or early miniature circuit breakers.

Mill and warehouse conversions sometimes keep a three-phase supply from their industrial past. Where that feeds individual flats or units, a three-phase distribution board with RCBO protection per circuit may be the right answer. We price those separately.

Newer homes on the edges of town, including the developments on former industrial sites, usually already have modern boards. If yours does, we will tell you a change is not needed, and quote for whatever you actually need, such as a circuit for a car charger.

Included with every board change

Testing before and after, certification and Building Control notification are all part of the price.

How we price a new board in Frome

No two Frome boards are the same, so we don't publish a price list. Board position, tails, bonding and the condition of the circuits all affect the price. The written quote follows a survey or a phone and photo consultation, with VAT on a separate line, and the price is fixed. Quotes are free.

How we fit the board

Most homes are a single day. Large period houses with several sub-boards take longer.

  1. Circuits are tested before anything is disconnected.
  2. The supply is isolated, and the old board removed without damage to the surface behind it.
  3. The new board is fixed and each circuit connected to its own RCBO.
  4. Tails and bonding are upgraded as quoted.
  5. Final testing, power restored, certificate emailed.

Board changes in the Frome villages

Village houses around Frome are often older than the town’s, and many are listed. We change boards in Norton St Philip, Beckington, Rode, Hinton Charterhouse, Mells, Great Elm, Nunney and Buckland Dinham, taking the same care over position and fixings.

For listed buildings needing more than a board, see heritage rewires in Frome.

Consumer unit questions from Frome

Can the new board go somewhere less visible?
Often, yes. A short move to a cupboard or utility room is common. The tails have to reach from the meter, so we look at the route before agreeing a position.
My house is listed. Do I need permission for a new board?
Like-for-like replacement in the same position rarely affects historic fabric, but anything that alters the building may need listed building consent. If in doubt, speak to the council’s conservation officer before work starts. We plan fixings and routes to keep any impact to a minimum.
Why do you only fit RCBO boards?
Because a fault on one circuit then only trips that circuit. With a split-load board, one fault can switch off half the house.
Do you work on three-phase supplies in converted buildings?
Yes. Three-phase distribution boards are priced separately after a survey.
Will the old wiring work with a new board?
We test every circuit first. If any circuit has a problem, we tell you and price the fix before going ahead.
