Standards & equipment we use
GW Property Maintenance Ltd carries out every distribution board upgrade to BS 7671 18th Edition, including the latest amendments, and for commercial sites in line with the Electricity at Work Regulations 1989. New boards have metal enclosures, a main isolator, RCBOs or MCBs and RCDs sized to each circuit, and surge protection where it is recommended. Distribution board wiring is done with correctly sized cable, clean terminations, colour-coded conductors and a clear circuit chart, so each circuit can be identified and isolated safely. Boards are built to BS EN 61439, and we can supply and fit boards from leading makers such as ABB, or upgrade an existing board. Every circuit is tested with a calibrated Megger multifunction tester before handover, and safe isolation uses lock-off devices and a proved voltage indicator. As a NICEIC Approved Contractor, we self-certify notifiable work in homes under Part P and issue the correct Electrical Installation Certificate.
What are distribution board upgrades in Tonbridge?
A distribution board upgrade is the replacement or extension of the board that splits your incoming electricity supply into separate protected circuits. In a home this board is called a consumer unit or fuse box, and in commercial and industrial premises it is a distribution board. An electrical distribution board upgrade adds modern RCBO protection, spare ways and clear labelling, so faults trip the right circuit and your installation can carry new loads safely.
Key Takeaways
- A distribution board upgrade means replacing or extending the board that distributes power to your circuits, with modern RCBO protection, spare ways and clear labelling.
- A single phase board change usually takes half a day to a day, and a 3 phase or commercial board typically takes one to two days, with power off for part of the work.
- Typical reasons to upgrade are rewirable fuses, a non-metal enclosure, missing RCD protection, no spare ways, damage, or an unsatisfactory EICR.
- Every upgrade is tested to BS 7671, with the correct certificate issued within 48 hours and a 5-year guarantee on installation work.
- Cost depends on the size and type of board, the number of circuits and the condition of existing wiring, so a free site visit and a written quote come first.
How does an electrical distribution board upgrade work?
The electrician first surveys the existing board, circuits and supply, and tests each circuit. Power is isolated, the old board is removed and the new board is mounted, with each circuit re-terminated, protected and labelled. Earthing and bonding are checked, surge protection and spare ways are added where needed, and every circuit is tested before the power goes back on. You then receive a certificate and a circuit chart.
Why does it matter in Tonbridge?
Many Tonbridge homes still have old fuse boxes or plastic consumer units, including Victorian terraces near Quarry Hill and 1930s and post-war houses in Cage Green and Higham Wood. Commuters who want an EV charger from home, and owners adding a heat pump or loft room, often find the board has no spare ways. Shops on the High Street, workshops and units on Tonbridge's trading estates also outgrow boards as equipment and tenants change. A distribution board upgrade in Tonbridge protects against shock and fire, and gives you room to grow.

How does the distribution board upgrade process work?
Free quote & site visit
An electrician visits, inspects your existing board and circuits, and discusses what you want to run now and later. A written, no-obligation quote follows.
Plan and shutdown agreed
We confirm the board size, protective devices, spare ways and the date, and plan any power shutdown around your home, tenants or trading hours.
Work carried out
The old board is isolated and removed, the new board is fitted, every circuit is re-wired neatly and protected, and earthing and bonding are checked.
Testing & certification
Every circuit is tested with calibrated Megger equipment, then the correct certificate and a circuit chart are issued within 48 hours.

What affects the cost of distribution board upgrades in Tonbridge?
The cost depends on the board and the property rather than one flat rate. The main factors are:
- Single phase or 3 phase: A 3 phase board needs more protective devices and heavier cable than a single phase board.
- Number of ways and circuits: More circuits, and spare ways for future loads, increase the size and cost of the board.
- Type of protection: RCBOs cost more than MCBs with a shared RCD, but isolate faults circuit by circuit and are easier to live with.
- Make and specification: Boards from different makers, such as ABB, vary in price, and extras like surge protection and metering add to the total.
- Condition of existing wiring: Old or undocumented wiring may need tracing, labelling or repair before the new board can be certified.
- Earthing and bonding: Upgrading these to current standards can add work in older properties.
- Board position: Moving a board needs extra cable and making good, while replacing it in place costs less.
- Access and working hours: Out-of-hours work to avoid a shutdown during trading can cost more than daytime work.
- Repairs found: Faults or damage discovered during testing are quoted separately, so you can approve them before they start.
- Making good: Plastering and redecorating after moving a board are usually separate from the electrical quote.
A free site survey is the only way to give an accurate figure, since two boards can need very different amounts of work.
Why landlords and business owners in Tonbridge need this
Landlords of rented homes in England must have an Electrical Installation Condition Report (EICR) at least every 5 years, and an old fuse box, a board with no RCD protection or a damaged board often leads to an unsatisfactory result. A distribution board upgrade gives you a clear record for the EICR, your insurer and your letting agent. Business owners also need a safe, documented board, because under the Electricity at Work Regulations 1989 employers and building owners must keep electrical systems safe, and fixed wire testing is commonly recommended every 5 years for shops and offices and every 3 years for industrial premises. A commercial distribution board upgrade with clear labelling saves time every time something needs isolating.
Why local matters for this service
Tonbridge sits on the River Medway, with Victorian terraces, 1930s houses and newer developments, plus a High Street of older converted buildings and workshops on its trading estates. As a local team based in West Malling, we know what is behind the walls in these properties, and we plan boards around solid brick, tight cupboards and limited space. For properties near the Medway floodplain, boards are mounted above ground level where possible. Replacing a consumer unit or board in a home is notifiable under Part P, and we self-certify it, so you do not need a separate council application. For commercial and industrial boards, we agree shutdowns with you in advance.
Standards and methods used
Every board is installed to BS 7671 18th Edition with metal enclosures, RCBO or RCD protection, clear distribution board wiring and labelling, calibrated Megger testing, safe isolation with lock-off and a full certificate. The finished work is safe, documented and ready for inspection.

Distribution board upgrades in Tonbridge Frequently asked questions
A single phase board change usually takes half a day to a day. A 3 phase or commercial board typically takes one to two days, depending on the number of circuits. Power is off for part of the work, and for businesses we can work out of hours to keep you trading.
A repair is enough when one protective device has failed and the board is otherwise sound, modern and in good condition. We recommend replacement when the board has rewirable fuses, a plastic or damaged enclosure, no RCD protection, burnt connections, no spare ways or obsolete parts. We inspect the board at the site visit before advising you, and distribution board upgrade repair work is quoted separately.
A 3 phase distribution board upgrade replaces or extends a board that serves three live phases at 400V, used for workshops, farms, units and larger buildings. It balances loads across the phases and gives each machine, motor or charger its own protected circuit. We also check phase rotation and fault levels before handover.
We can supply and fit boards from leading makers such as ABB, and upgrade or extend an existing ABB distribution board. We also supply 110V distribution boards, transformers and yellow industrial sockets for sites and workshops. We confirm the make and specification at the site visit.
Yes. Replacing a consumer unit or distribution board in a home is notifiable under Part P, and we self-certify it and issue the correct certificate within 48 hours. For commercial premises, we issue an Electrical Installation Certificate with test results. Keep it safe, as insurers, buyers and letting agents may ask for it.
