Recording levels one to four and who is qualified
Level 2 is a description, Level 3 is an analysis, and the difference decides who can do the work. How to agree the level, brief the recorder and get the record accepted.
Historic building recording is specified by level, one to four, and the level decides who is competent to do the work. Level 1 is a basic visual record that a careful surveyor can produce. Level 4 is a full analytical record with documentary research, and it needs an architectural historian or buildings archaeologist. Most planning conditions land at Level 2 or Level 3, and most disputes about discharge come from someone producing Level 2 work against a Level 3 condition.
The levels come from Historic England's guidance on recording practice, and they describe the depth of the record rather than the format it arrives in.
What each level demands
Level 1 is the minimum: a visual record, essentially photographic, with enough written material to identify the building, its location and its date. It is used for gazetteers and for buildings of limited interest, and it is rarely enough to discharge a condition on a building worth recording.
Level 2 is a descriptive record. The building is examined and described systematically, inside and out, with a photographic record and drawings where they add to the description. It records what the building is, not how it came to be that way.
Level 3 is an analytical record. It includes everything in Level 2 plus an account of the building's origins, development and use, based on examination of the fabric and on readily available documentary sources. Phasing matters here: the record has to say which parts are earliest and how the building changed.
Level 4 is the same again, with systematic documentary research and a fuller drawn and photographic record, used for buildings of high interest or where the fabric evidence alone cannot explain the building.
| Level | Written account | Drawings | Documentary research |
|---|---|---|---|
| 1 | Identification only | Rarely | None |
| 2 | Systematic description | Where they aid description | None expected |
| 3 | Description plus development and phasing | Plans, sections, elevations as needed | Readily available sources |
| 4 | Full analytical account | Full drawn record | Systematic |
Skills needed at the higher levels
At Level 2 the skills are observational and methodical. Someone who can read a building, describe materials and construction accurately, and photograph it to a standard can produce a competent record.
At Level 3 the requirement changes. Phasing a building means recognising a scarf joint, a blocked opening, a change in brick bond, a truncated moulding, and knowing what those mean in sequence. That is a trained skill, and it is where architectural technologists and general practice surveyors most often produce records that a conservation officer rejects as descriptive rather than analytical.
At Level 4 documentary research is added: deeds, estate papers, tithe and enclosure maps, historic ordnance survey editions, census returns, sale particulars and photographs held by the county record office and the local studies library. Knowing which sources exist and how to read them is a separate competence again.
Photography, survey and documentary research
The photographic record is the part most often under-specified in the brief and most often criticised on submission.
- General views of the exterior from each aspect, and of the setting
- The overall appearance of principal rooms and circulation spaces
- Any external or internal detail relevant to the design, development or use
- Any dates or inscriptions, machinery or fittings
- A scale in every detail shot, with a photographic register keyed to a plan
Lighting, a tripod and a camera held level matter, because a record photograph with converging verticals and blown highlights is not a record. Historic England publishes standards for this and a competent recorder will follow them without being asked.
The drawn record can be measured by hand, by rectified photography, by photogrammetry or by laser scanning. The method matters less than whether the output is scaled, dimensioned and legible as a record in twenty years. Ask what will be produced, at what scale, and in what file formats for the archive.
Where an architect is not the right author
This is not a criticism of architects. It is a difference of discipline.
An architect's drawings describe a building as it will be, or as it is for the purpose of designing change. A recorder's drawings describe a building as evidence, with phasing, with what is uncertain marked as uncertain, and with the parts that are of no design interest recorded anyway because they carry the evidence.
Where a practice offers to do the recording alongside the design work, ask who within the practice will do it and what their accreditation is. The answer is sometimes entirely satisfactory. Where it is not, the cost of a rejected record includes a delayed condition discharge on a live site.
For accredited individuals and organisations, look for membership of the Chartered Institute for Archaeologists at associate or member grade, or a practice registered with it, and ask for examples of records at the level specified. Briefing a specialist when the site data is incomplete covers how to scope that appointment.
Agreeing the level with the conservation officer
Do this before commissioning, in writing, and do it even where the condition names a level.
Conditions are frequently drafted loosely, requiring a record "in accordance with Historic England guidance" without stating a level. That ambiguity is resolved at discharge stage, which is the worst possible time. Write to the conservation officer or the county archaeologist, propose a level with reasons, and ask them to confirm.
Where a written scheme of investigation is required, it should state the level, the scope, the photographic and drawn outputs, the documentary sources to be consulted, the archive destination and the timetable relative to the works. Get it approved before anyone opens a wall.
The recording usually has to happen before alteration or demolition, and in some cases during the works where fabric is exposed. A condition requiring a record before works begin, discovered after the scaffold is up, stops the job.
Archive deposition
The record is not finished when the report is written. It has to be deposited, normally with the local historic environment record and often with a digital archive, in formats the archive accepts.
Confirm at appointment who pays the deposition fee, what file formats are required, and how long the archiving takes, because a condition is not discharged until the deposit is confirmed. Digital archives have specific format requirements and a report delivered only as a flattened PDF can fail acceptance.
Commissioning so the condition is discharged first time
- Read the condition and identify the level, or the ambiguity.
- Write to the conservation officer or county archaeologist and agree the level and scope.
- Prepare or commission a written scheme of investigation and get it approved.
- Appoint an accredited recorder, by name, with examples at that level.
- Fix the site access dates against the construction programme, before the scaffold and before any stripping out.
- Agree the archive destination, formats and fees at appointment.
- Submit the record with the approved scheme attached, so the officer can check it against what was agreed.
A Historic Building Recording draft can structure the written account and the register before the recorder visits, and an Archaeological Desk-Based Assessment often supplies the documentary context the higher levels need. Professional review and sign-off can be arranged through the professional directory.

Frequently asked questions
What is the difference between Level 2 and Level 3 recording?
Level 2 is a descriptive record: a systematic account of the building as it stands, with photographs and drawings where they help. Level 3 adds analysis, an account of the building's origins, development and use based on the fabric and readily available documentary sources, including phasing. Level 3 needs someone trained to read a building.
Who is qualified to produce a Level 3 record?
Usually a buildings archaeologist or architectural historian, accredited through the Chartered Institute for Archaeologists at associate or member grade, or working for a registered organisation. Ask for the individual's name, their accreditation, and examples of records at the level your condition specifies rather than accepting a practice brochure.
My condition does not state a level. What do I do?
Agree one in writing with the conservation officer or county archaeologist before commissioning anything. Conditions requiring a record in accordance with published guidance without naming a level are common, and the ambiguity is otherwise resolved at discharge stage, when the work has already been paid for.
When does the recording have to happen?
Normally before alteration or demolition, and sometimes during the works where fabric is exposed. Check the condition wording against your programme early, because a requirement to record before works begin that is discovered after the scaffold is up will stop the job while access is arranged.
Is the condition discharged when the report is delivered?
Not usually. Most conditions also require the record to be deposited with the local historic environment record and often a digital archive, in accepted formats. Confirm the destination, the formats, the fee and the timescale at appointment, because a flattened PDF alone can fail archive acceptance.
