The bathroom quote says “lay tiles”. Once the lining comes off, the job can become waterproofing, substrate repair, demolition or structural work. A Tasmania tiler contractor licence check must follow the work, not the trade name.
Tasmania’s licensed-occupations directory does not present tiler as a standalone occupation at directory level. That is not blanket permission to accept every part of a bathroom renovation. Describe the exact work to Tasmania’s regulator before you quote it.
Do you need a Tasmania tiler contractor licence?
Start with the direct answer. Tile installation is not listed as a standalone licensed occupation in the Consumer, Building and Occupational Services licensed-occupations directory (opens in a new tab).
The job title does not settle the question. Your scope might include work covered by a broader building-services category or another licensed occupation. Waterproofing, damaged framing, plumbing disconnection and electrical work cannot be treated as ordinary tile laying just because they appear in the same bathroom.
Search phrases such as TAS tiling licence, Tasmania tiler registration and Tasmania building services licence are useful starting points. They are not proof of an official category. Use the current CBOS wording in your records and quote.
For each new kind of job, ask CBOS which category covers the exact work, who may contract for it and whether a responsible practitioner must be named. Write down the answer before you promise the work.
Split the Tasmania tiling job into work you can check
Break the scope apart before you price it. One line saying “complete bathroom tiling” hides too much.
Use separate scope lines for:
- demolition and removal of existing finishes
- inspection of the exposed substrate
- replacement or repair of wall and floor substrates
- falls, screeds and wet-area preparation
- waterproofing and its responsible party
- tile supply, cutting, laying and finishing
- movement joints, sealants and penetrations
- plumbing disconnection and reconnection
- electrical isolation or alteration
- structural alteration or framing repair
- rubbish removal and final cleaning
This list is not a licence ruling. It gives CBOS and the permit authority something specific to answer.
Is tile installation different from waterproofing or substrate repair?
Treat each as separate work until the regulator confirms otherwise. Tile installation deals with the finished tiled surface. Waterproofing deals with the wet-area barrier. Substrate repair can range from replacing a suitable lining to repairing moving or damaged building elements.
Do not bury those tasks inside “preparation”. Record the substrate you expect to find, who accepts it and what happens if demolition exposes damage. Use a tiler waterproofing and substrate checklist before accepting the surface.
Keep other licensed trades outside your tile allowance
Name the plumber, electrician, builder or other trade responsible for their part. Do not include their work as an unnamed allowance and sort out responsibility later.
If the client has engaged those trades directly, say so. If your business plans to engage them, check whether your contracting role changes the licence or contract position before including their work.
Ask CBOS about the exact scope and contracting role
Do not ask only, “Does a tiler need a licence?” That question is too broad.
Give CBOS a plain description of the proposed work. State whether your business will contract directly with the client, work as a subbie to a builder or supply labour for another contractor. Identify waterproofing, demolition, substrate replacement and structural work separately.
Ask these questions:
- Which current Tasmanian category covers each scope line?
- Can the business quote and contract for that work?
- Does a practitioner need a particular licence or registration?
- Must another contractor hold responsibility for part of the work?
- What details should be recorded on the contract or quote?
Treat your Tasmania tiler contractor licence check as a job document. Save the CBOS page, written response or call note with the date, scope discussed and name of the person who made the enquiry. Do not rely on a licence answer from an old job with a different scope.
Separate the business, practitioner and subbie records
A business registration answers who operates the business. A trade, practitioner or contractor licence answers who may perform or contract for regulated work. Keep those questions separate.
Record the legal entity giving the quote. Then record the person or business performing each regulated part of the job. If a builder asks for evidence before issuing a work order, send the category and responsible-party details that apply to the actual scope.
Does using a licensed subcontractor let your business quote the whole job?
Not automatically. A subbie’s credentials do not give your business blanket authority to sell every part of the renovation.
Ask CBOS whether your business may contract with the client for that work and subcontract its delivery. Record who is contracted to the client, who supervises the work and who supplies required completion documents. Put the same allocation in the quote.
Do not write “licensed trades where required”. Name the responsible trade and the work assigned to them.
Ask the permit authority before booking the work
Occupational licensing and building approval are different checks. A licence answer does not tell you whether the proposed alteration needs a permit.
Start with the CBOS building and renovating information (opens in a new tab). For a project-specific answer, give the relevant Tasmanian council permit authority the site address and exact proposed work.
Who checks whether a Tasmanian tiling job needs a building permit?
The relevant council permit authority handles the project-specific permit question. Describe demolition, changes to walls or floors, structural repairs and wet-area work. Do not ask about “tiling” in general.
Record the answer and who will obtain any required approval. Do that before booking labour, ordering tiles or promising a start date. If the design changes, ask again about the changed work.
Put the checked scope into the quote
Write only the work your business is authorised and prepared to deliver. Price that scope from labour, materials, subcontractor costs, overhead and markup. Keep uncertain work out of the fixed scope until it has been inspected and checked.
For a bathroom, state:
- the walls and floors being tiled
- who supplies the tiles and nominated finishes
- the substrate assumed at the time of quoting
- the preparation included in the price
- who performs and documents waterproofing
- which demolition and disposal work is included
- which plumbing, electrical and structural work is excluded
- who supplies access, water and power
- how concealed damage will be handled
- which licence or responsible-party details apply to regulated work
Use the bathroom tiling quote scope guide to turn the inspection into clear inclusions, assumptions and exclusions.
What licensing details belong in the job record?
Keep the official category wording that applies to the checked work. Record the licence or registration holder, their role, the scope they control and any supporting documents supplied for the job.
Do not add a number to the quote merely because a client expects one. First confirm whose number applies and what work it covers. Keep the evidence with the accepted quote, not in a separate folder nobody checks on site.
Stop when demolition exposes different work
The wall lining comes off. The substrate is damaged or moving. The accepted tile-only scope no longer matches the job.
Stop. Photograph the condition. Do not cover it, repair it or tell the client it is included. Describe the newly exposed work and ask CBOS or the permit authority another question if the licence or approval position has changed.
Then decide who will do the work. It may stay with your business, move to a suitably authorised subbie or return to the builder or client. Price it only after responsibility is clear.
Write a variation that states:
- the exposed condition
- the extra or changed work
- the party responsible for that work
- any effect on the program of works
- the added labour, materials and subcontractor cost
- the revised price and approval
Get the client’s approval before restarting. The control is the same across trades: an exclusion does not become free work because the crew is already on site.
Worked example — sample currency units
The house example is electrical, but the scope control is the same. R. Chen’s quote Q-1847 for 14 Oak Street was 1,105 and excluded chasing because the ceiling was lined. Extra cable and chasing were approved on site as a 160 variation, so invoice INV-1847 became 1,265.
Those figures are sample currency units, not a rate card. The variation costs are not given, so profit cannot be calculated from the 1,265 invoice. For the site process, use the Australian variation guide for recording changed work.
Save a pre-start record for the Tasmania job
Keep one short decision record beside the quote. Make it easy for the person scheduling the job and the tradie on site to read.
Site address: [address] Client and contracting entity: [names] Tile installation scope: [surfaces and finishes] Demolition scope: [included work or excluded] Substrate assumption: [condition assumed] Waterproofing responsibility: [business or person] Structural work: [responsible party or excluded] Plumbing work: [responsible party or excluded] Electrical work: [responsible party or excluded] CBOS category checked: [official wording] Licence or registration holder: [name and details where required] Permit authority answer: [answer, date and contact] Subbies assigned: [business, work and credentials] Variation method: [written approval required before extra work] Evidence saved: [links, notes, photos and documents]
Check the actual construction risks through WorkSafe Tasmania’s industry and safety guidance (opens in a new tab). Use WorkSafe Tasmania for workplace safety questions, not contractor licensing or building permits.
After completion, compare the accepted scope with the labour, materials, subbie invoices and rework recorded against the job. The tiler job-costing close-out process shows what to capture without mixing licence checks with profit calculations.
Before the next enquiry becomes a booking, create this record and label the regulatory note “Tasmania tiler contractor licence”. Attach the current CBOS answer, the permit response and the named responsible parties.
Then send the checked scope to the client for acceptance. Book the crew only when the work, authority and responsibility all match.
