Chartered overhead line and electrical engineering for 11kV to 400kV schemes across Great Britain — designed to BS EN 50341 and ENA technical specifications, from feasibility through to energisation.
Trusted by network operators, contractors and developers
Placeholder client marks — swap for real logos when available
For TOs, DNOs, IDNOs, principal contractors and renewable developers.
Route selection, profiling, structural design and construction support for 11kV to 400kV overhead lines.
Primary and secondary design, studies and condition assessment for 11kV to 400kV substations.
Technical leadership, NEC contract support and stakeholder management from feasibility to energisation.
TOWER FAMILIES
Design, reassessment and refurbishment of the National Grid tower portfolio at 275kV and 400kV, alongside wood pole and trident pole distribution lines. Structural analysis is carried out to BS EN 50341-1 with the UK National Normative Aspects and the relevant NGET technical specifications.
Double-circuit lattice
The classic post-war 400kV double-circuit suspension family still forming much of the GB grid.
Assessment, uprating and refurbishment of L2 suspension and tension towers — including body extensions, leg extensions, member replacement and foundation reassessment for higher conductor tensions.
Heavy-duty lattice
Robust 400kV family used where higher loading, longer spans or larger conductors are required.
Loading tree development, member and bolt-group checks, and TOWER modelling for L8 structures on reconductoring and HTLS uprating schemes.
Low-height / compact lattice
Lower-profile 400kV design used where visual impact or clearance constraints govern.
Clearance and profile verification, wind and ice load cases to BS EN 50341, and coordination of L12 structures with planning and landscape constraints.
Modern double-circuit lattice
Later-generation 400kV double-circuit family used on new-build and diversion schemes.
New-build and diversion design using L13 towers, including foundation loading, tower spotting and construction sequencing within outage windows.

Design risk management on UK schemes
The overhead line design was delivered ahead of our outage window and cleared the TO's technical assurance first time. Genuinely rare on a scheme of this complexity.
Clear, pragmatic engineering advice throughout the connection process. The earthing and fault level work removed a major risk from our grid application.
Acted as our client engineer on an NEC4 contract and kept the design interfaces under control. Excellent stakeholder handling with landowners and the DNO.
Engineering the backbone of GB transmission, distribution and renewable connections.
Uprating of a 400kV transmission corridor using HTLS conductor, including structure loading reassessment and foundation checks within a single outage window.
Design of a 132kV collector substation and connection assets for a large-scale solar farm under ENA ER G99, with earthing and fault level studies.
Outline the voltage level, scope and programme and you'll receive a considered response within one working day.
