A tower survey is one of the least forgiving records in field work. The steelwork holds antennas, and sometimes people, above a public area. If a defect is missed, or logged vaguely three hours after it was seen, the record is worth little to the engineer who acts on it or the insurer who reads it later. The value of a checklist is not the list. It is that every item gets a finding and a photo at the point of observation.

Mast and tower inspection checklist for the UK.
What a structural and antenna survey on a lattice tower, monopole or rooftop mast should cover, how the Work at Height Regulations 2005 shape the job, and how to capture the record without filling it in from memory afterwards.

The point
Record the defect where you find it.
A corrosion note taken at the point of observation, with a photo of the exact bolt, beats a survey rebuilt at the desk that night. The checklist is not the value. The value is that every item gets a finding and a photo before the engineer comes back down.
The survey in three parts
What a tower survey covers.
Structure
Steelwork and condition
Corrosion, member deformation, bolt condition and torque marks, welds, foundations, coatings and galvanising, guy wires and tensions where fitted.
Access and safetyClimbing the mast
Fall-arrest systems, ladders and rest platforms, anchor points, safe-access provision and aviation obstruction lighting, all under the Work at Height Regulations 2005.
PayloadAntennas and feeders
Antenna mounts and alignment, feeder runs and cable management, connectors and weatherproofing, ancillary steelwork and any new proposed loading.
Not legal advice
Follow the client spec and current standards.
There is no single statutory format for a tower survey. The work sits under the Work at Height Regulations 2005, the client operator's own survey specification and relevant structural standards. Use this checklist as a starting frame, not a compliance guarantee, and confirm the current requirements before you rely on it.
Survey from WhatsApp
No app install. No training.
The survey arrives as a WhatsApp chat. Each item is a message; the engineer replies with a photo and a note as they climb. The report writes itself.
The short version
- A tower survey covers three broad areas: structural condition, safe access and working-at-height provision, and antenna and feeder payload.
- Working at height is governed by the Work at Height Regulations 2005. Access equipment and any lifting gear used on the climb bring LOLER 1998 into play.
- There is no single statutory report format. Follow the client operator's survey specification and current structural standards.
- Record each finding with a photo at the point of observation, not reconstructed at the desk that evening.
- The checklist does not make the survey valid. The competent structural inspector does. This is a starting frame, not legal advice.
Part one
Structural condition
The structural walk covers corrosion and coating breakdown, member deformation or impact damage, bolt condition, torque marks and any missing fixings, weld condition, and the state of galvanising or paint systems. On guyed masts it extends to guy wires, tensions, anchors and turnbuckles. At the base it covers foundations, holding-down bolts and grouting.
Each item wants a clear finding, a severity, and a photograph of the exact location. A note that reads corrosion on leg B at the third bracing node, with the photo attached, is a record. Corrosion, some, is not. Quickler prompts for the photo at the point of observation so it is tied to the finding rather than sorted out later.
Part two
Safe access and working at height
Working at height on a mast or tower is governed by the Work at Height Regulations 2005: plan the work, use competent people, use suitable equipment, and record it. The survey checks the fall-arrest system, fixed ladders and safety rails, rest platforms and anchor points, and safe-access provision generally. Where the tower carries aviation obstruction lighting, that is checked too.
Access equipment and any lifting gear used to get the surveyor or tools up the structure fall under LOLER 1998, which requires thorough examination and records of lifting equipment and accessories. Quickler can record that the access and lifting gear were in examination and photograph the tags, as part of the survey evidence. It does not carry out the LOLER examination or replace the competent person who does.
Part three
Antennas, feeders and RF
The payload walk covers antenna mounts and alignment, feeder and jumper runs, cable management and cleats, connector condition and weatherproofing, and any ancillary steelwork. Where a survey supports new loading, it records the existing configuration so the structural assessment can be done against it.
Active antennas radiate. Sites can have RF exposure zones assessed against ICNIRP guidelines, with exclusion zones, permits and isolation forming the safe system of work set by a competent RF safety assessor. Quickler can record that the correct permits and isolation were in place and photograph the signage, as evidence. It does not assess exposure and does not replace an RF safety assessment. Check current ICNIRP guidance and your operator's RF safety policy.
The record
Capturing it without the van write-up
The failure mode on tower surveys is the same as everywhere in field work: the engineer climbs, sees everything, comes down, and writes it up later from memory and a camera roll of unlabelled photos. Findings drift, photos get mismatched, and the report is weaker than the survey was.
Quickler turns the checklist into a WhatsApp conversation. Each item arrives as a message; the engineer replies with a photo and a short note, or a voice note that is transcribed. The finding and its photo are bound together at the moment of observation. The completed survey report generates automatically and the office sees the status on a dashboard. The tool captures the evidence. The competent inspector still carries the judgement.
Questions, answered
What does a mast or tower inspection checklist cover?
Broadly three areas: structural condition (corrosion, members, bolts, welds, foundations, guys), safe access and working-at-height provision (fall arrest, ladders, platforms, obstruction lighting), and antenna payload (mounts, feeders, cable management, weatherproofing). The exact items follow the client operator's survey specification.
What regulations apply to tower inspections in the UK?
Working at height falls under the Work at Height Regulations 2005. Access equipment and lifting gear used on the climb fall under LOLER 1998, which requires thorough examination and records. RF work near live antennas is assessed against ICNIRP guidance by a competent RF safety assessor. There is no single statutory report format, so follow the client specification and current standards, and treat this checklist as a starting frame rather than legal advice.
Can a tower survey be recorded on a phone?
Yes. Quickler runs the survey as a WhatsApp conversation. The engineer receives each checklist item as a message and replies with a photo and a note, or a voice note, as they climb. The completed report generates automatically. No separate app or login is required.
Does the checklist make the survey compliant?
No. The checklist and the software capture the evidence and generate the report. They do not make the survey valid. A competent structural or rigging inspector, working to the client specification and current standards, carries that. Confirm current requirements before relying on any template.
