UK Electrical Designer Required - LV DB / UPS Design

I am looking for a competent UK-based electrical designer to support a small commercial LV electrical design package.

The project involves design support for upgrading an existing DB-fed circuit to a dedicated new distribution board, incorporating a UPS feed and maintenance bypass switch. There may be two similar locations.

Required scope:

RIBA Stage 4 electrical design support
single line / schematic arrangement
cable sizing calculations
voltage drop calculations
protective device selection
review of existing DB information, fault level data and earthing arrangement
UPS / maintenance bypass integration notes
Stage 6/as-built update based on installer redlines and final installed details

Required experience:

UK LV electrical design experience
strong working knowledge of BS 7671
experience with commercial distribution boards, UPS supplies and maintenance bypass arrangements
ability to produce clear calculation outputs
ability to work from existing drawings, DB schedules, site information and installer-provided details
previous examples of similar design work, redacted if necessary

Please include in your response:

your UK-recognised qualifications
relevant professional memberships or registrations, if applicable
confirmation of software/calculation method used, such as Amtech / Trimble, ElectricalOM, ETAP or equivalent
example calculation output or redacted previous design package
confirmation of professional indemnity insurance, if held
availability over the next 1 to 2 weeks
fixed fee or day rate indication

I am not looking for the cheapest bidder. I need someone competent, reliable and able to provide calculation-backed design work suitable for review and issue within a UK commercial electrical project environment.

Please start your response with “BS7671 UPS DB” so I know you have read the brief.
