Board replacements, sub-mains and capacity upgrades for offices, retail, schools and commercial premises across East Lancashire. Tested, certified and labelled before we leave site.
Distribution boards have a working life of around twenty-five to thirty years. Most commercial premises have boards installed in the late 1990s or early 2000s and are now well into the back end of that window. They’re not necessarily dangerous, but they’re failing inspections.
Modern Wiring Regulations require RCBO protection on most final circuits, surge protection on the incomer, and labelling and schedules that match the actual installation. Older boards rarely meet any of these standards. The result is a string of EICR observations and code C1/C2 fails that turn into insurance issues.
A proper board replacement isn’t just swapping the unit. It’s load-assessing the building, sizing the new board with capacity for future growth, installing the right protection devices on the right circuits, labelling everything, issuing fresh certificates, and updating the schedule. We do all of that as one job.
The bit nobody talks about is the disruption. A board change typically means an hour of downtime per board minimum. We schedule installs to fit your trading hours and have temporary supplies in our van for anything safety-critical. Most board replacements are completed inside a working day.
We walk the site, identify existing boards, measure existing demand, photograph specific concerns and assess existing circuit schedules. Survey takes one to three hours.
Within forty-eight hours we send a written quote covering board, sub-main work if needed, protection specification, labelling, schedule and certification. Where there are options, both are priced.
We confirm the install window with you - usually fitting around opening hours or in planned downtime. Where temporary supplies are needed for critical loads, we plan and bring them.
Isolation, removal of old board, installation and labelling of new board, testing of every circuit, completion of schedule. Most single-board changes inside a working day.
Minor works certificate issued, updated schedule emailed and printed for the board, warranty documentation handed over, old board removed from site.

Most single-board replacements are completed inside a working day, including testing and certification. Larger sites with multiple boards are scheduled across consecutive days or weekend windows.
Yes – all our board installs are 18th Edition Amendment 2 compliant from day one, with the appropriate RCBO protection and surge protection where required. We re-issue the EICR after install if needed.
We default to RCBOs on all final circuits – they’re now the BS 7671 default and give better discrimination if a single circuit faults. Where budget is tight we’ll price RCD plus MCB as an option.
If the load assessment shows the incoming supply is undersized for actual demand we’ll quote a separate uplift to the DNO and handle that liaison for you.
Yes – every board change comes with a fresh circuit schedule produced from first principles. Soft copy emailed, printed copy left at the board.
Free site survey. Quote and payback figures within forty-eight hours. No pressure, no follow-up calls if it’s not for you.
