Built for specialist subcontractors

Capture extra work before it disappears between site and office.

VariationDesk gives technicians and site teams a simple way to record variations when they happen, then gives the office the evidence, quantities, approvals and history needed to make the commercial decision.

The problem it is designed around

Busy teams can still lose variation value.

Technicians do extra work but forget to raise it.

Photos stay in camera rolls or WhatsApp instead of the variation record.

The office hears about a change days or weeks after the instruction.

Commercial teams have to reconstruct what happened before they can price or claim it.

Site to commercial review

A focused variation workflow, not another full project-management system.

VariationDesk is deliberately narrow: capture the change, keep the evidence attached, record the response and give the office one history to review.

Capture the instruction

Record what changed while the detail is still fresh, using a simple mobile flow or voice-assisted capture.

Keep the evidence with it

Add photos, files, notes, quantities and site context to the same variation instead of spreading them across separate apps.

Record the response

Use on-device acknowledgement or secure remote review when the authorised person is not physically on site.

Let the office review it

Commercial and finance teams see the complete history together before the record is approved, reported or prepared for invoicing.

Common questions from subcontractors.

These are the practical questions VariationDesk is designed to answer for electrical, M&E, HVAC, fire, security, fit-out and other specialist teams.

What software helps subcontractors capture variations on site?

VariationDesk is variation management software for UK specialist subcontractors. Site teams can capture the instruction, photos, files, quantities, GPS context and signatures against the correct project, while the office reviews the commercial record before billing.

Can technicians record extra work before they forget it?

Yes. VariationDesk is designed to capture additional work at the point it happens rather than reconstruct it from messages, camera rolls or memory at the end of the week or month.

Can VariationDesk work on sites with poor mobile signal?

Yes. The mobile workflow can hold queued records on the device and sync them when connectivity returns. External actions such as sending a remote review link still need a connection.

Can customers or main contractors sign off remotely?

Yes. An authorised reviewer can receive a secure remote review link without needing a paid VariationDesk workspace seat. On-site signatures can also be captured directly where appropriate.

Is VariationDesk only for electrical contractors?

No. It is built for specialist subcontractors where site instructions and additional work are common, including electrical, M&E, mechanical, HVAC, fire protection, security, fit-out, glazing, groundworks and similar trades.

Does VariationDesk replace NEC or JCT notices?

No. VariationDesk keeps the operational and commercial evidence together, but each contractor remains responsible for following the notice, authority and timescale requirements in its contract.

Test it on real variation work.

The assisted pilot is designed around a small number of live users and projects so you can see whether the workflow improves what reaches the office before committing to a paid plan.
