Drawings & Surveys

Technical Plans and On-Site Electrical Assessments

We produce detailed, BS 7671-compliant electrical drawings and site surveys to support commercial upgrades, fit-outs and compliance sign-offs.

Whether you need plans for what’s already in place or guidance for a new build, we deliver clear documentation to help you move forward safely and confidently.

All documentation meets UK safety standards and is created by qualified professionals who understand what’s needed for approval, inspection and insurance.

What We Offer

Electrical Drawings

We create clear, professional plans tailored to UK safety regulations. These can help speed up approvals, support insurance claims and make fit-outs more efficient.

Electrical Surveys

Our surveys support safe upgrades, maintenance and compliance with UK regulations.

EICRs (Electrical Installation Condition Reports) for landlords, insurers or building owners
Condition surveys to plan refurbishments or upgrades
Thermal imaging to detect faults, and lux level tests for workspace safety
Emergency lighting inspections for safety and legal compliance

FAQs – Electrical Drawings & Surveys

Q: What are electrical drawings and why do I need them?

Electrical drawings are plans showing the location of lighting, power, data, and emergency systems. They’re essential for staying compliant with UK safety regulations, reducing installation errors, and helping with future upgrades or repairs.

Q: What’s the difference between a survey and a drawing?

A survey checks the condition and layout of existing systems. A drawing shows where systems are – or will be – placed. We often survey first, then create or update drawings based on the findings.

Q: When do I need an electrical survey?

Before buying or leasing a commercial property
Before major upgrades, refurbishments or fit-outs
If you need a safety check (e.g. EICR for insurers or landlords)
If you suspect faults or ageing wiring

Q: What drawings might I receive?

Lighting and power layouts
Data and comms cabling diagrams
Emergency lighting and fire system coverage
Single-line or circuit diagrams
As-installed (as-fitted) plans for handover or insurance

Q: What happens during a survey?

We inspect wiring, sockets, lights, and distribution boards. Depending on the brief, we may use thermal imaging or lux level tests. You’ll get a report highlighting any faults, risks, or required actions.

Q: Can you work from existing plans?

Yes – but if the building has changed or the plans are outdated, we usually recommend a site visit to ensure accuracy.

Q: Do small jobs need drawings too?

Yes. Clear plans reduce miscommunication, help with quoting, and support legal compliance – even for smaller works.

Q: How will I receive the drawings?

As CAD files (DWG or similar) and/or PDF. We can also provide formats suitable for use in BIM models or digital facilities tools.

Q: Who uses the drawings?

Installers and electricians
Facilities or estate managers
Inspectors and compliance officers
Future contractors planning upgrades

Q: How much do drawings or surveys cost?

It depends on the site size and level of detail needed. We’ll give you a tailored quote after reviewing your plans – or following a site visit if required.
