Essential business documents for UK tilers in 2026

TL;DR: A tiler running their own business needs a core set of documents that protect them at three distinct points: before work starts, while work is underway, and at sign-off. Most disputes can be traced to one of two gaps: no written scope before work begins, or no sign-off record at the end. The documents that matter most are: a client services contract with payment milestones tied to tile-areas-completed, a scope of works template (critical where Building Regs apply to wet areas), a site visit risk assessment, a materials waste log (tile breakage variance is real), a RAMS for more complex work, a photo record practice (before, during, and after for warranty disputes), a snag-list and sign-off document, a sub-contractor agreement if another tiler is brought in, and invoice templates that record the right information for tax and CIS purposes. This post sets out each document, why it matters, and what it should contain for a tiling business specifically.

Running a tiling business without documentation is not just an administrative gap. It is a liability gap. A client who disputes the adhesion quality on a tiled shower enclosure six months after completion has very little ground to stand on if you have a photo record from before the first tile was laid, a signed scope of works, and a signed completion document. Without those, the dispute runs on memory and goodwill, which rarely favours the trade.

This is not paperwork for paperwork's sake. The right documents protect your income, limit your liability, and create an insurance trail that matters if a claim is ever made. They also make tax time faster: an accurate materials waste log and a clean invoice trail turn a quarterly MTD submission from an exercise in reconstruction into something that takes an hour.

A client services contract is the foundation document. For a tiler, it should set out:

• The parties: your business name and address, the client's name and address, and the site address if different.
• Description of work: a clear description referencing the scope of works document (below). The contract should not attempt to be the full technical specification. It references the specification.
• Payment milestones tied to tile-areas-completed. This is the critical element for tiling work. Rather than a single payment on completion, structure milestones around measurable stages: substrate preparation accepted and signed off, wall tiling to specified height complete, floor tiling complete, grouting and sealing complete, final snag inspection and handover. For bathroom or kitchen projects, three to four milestones is typical. Each milestone is invoiced and paid before the next stage proceeds.
• Materials supply: whether tiles, adhesive, grout, and edge profiles are client-supplied or contractor-supplied, and who bears the cost of breakage variance and over-ordering.
• Access to site: when and how the site will be accessed, and what facilities (water, power for wet saws, material storage area) the client will make available.
• Variation procedure: how changes to the agreed scope (client changes tile choice mid-job, adds an additional surface area) are authorised and priced. A simple clause stating that variations must be agreed in writing before work proceeds prevents scope creep from becoming an unpaid addition.
• Dispute resolution: the mechanism for raising and resolving disputes before escalating to legal proceedings.
• Liability limitation: your public liability cover and its limit; a statement that your warranty covers workmanship to specification, not waterproofing-system performance, which sits with the adhesive and membrane manufacturer's warranty and the designer's specification.

If you do nothing else before your next job: get a signed contract with payment milestones tied to tile-areas-completed before a single tile is touched.

The scope of works is the technical document that sits alongside the contract. It specifies what you will tile, to what standard, using what materials, and under what conditions.

A tiler's scope of works should include:

• Work description: the wall, floor, or surface to be tiled. Area in square metres, tile format, bond pattern, adhesive type, grout type and colour, edge treatment.
• What is included: surface preparation within your scope, setting out, tiling to specified area, grouting, sealing joints, fitting edge profiles, making good.
• What is explicitly excluded: substrate construction or repair (if another trade is supplying the substrate), Building Control submissions, plumbing connections, drainage installation, waterproof membrane installation if specified by a third-party designer. Explicit exclusions prevent the scope from expanding at the client's interpretation.
• Drawings and specifications referenced: if you are tiling to a designer's specification or a wet-room membrane system designer's instruction, reference the document number and date. You are installing to that specification. You are not warranting the specification itself.
• Substrate handover condition: a statement specifying the substrate condition you require before tile-laying begins (flat to specified tolerance, dry, sound, free from contamination). If the substrate does not meet this condition when you attend site, the scope makes clear that additional preparation is outside the quoted price.

Where Building Regulations apply (Part G for bathroom and sanitary provision, Part C for weather-resistance in wet areas), the scope of works should be clear that any compliance sign-off is the responsibility of the principal contractor or the designer, not the tiler. You are laying tiles to specification. You are not the statutory authority for Building Control sign-off.

Before work begins on any site, a site visit risk assessment documents the hazards you identified, how you assessed the risk, and what control measures you put in place. For a sole-trader tiler working on domestic projects, this does not need to be elaborate, but it does need to exist.

What to record:

• Date of visit and site address.
• Identified hazards: substrate condition, existing plumbing proximity, silica dust exposure (from cutting tiles), confined space in shower cubicles, wet floor slip risk during work, access to site.
• Risk level for each hazard (low / medium / high).
• Control measure for each hazard: dust extraction, respiratory protection, wet cutting to reduce silica dust, non-slip footwear, barriers and signage.
• Who will implement the control measures and when.

Silica dust is a specific hazard in tiling work that has received increased HSE attention. Wet cutting and appropriate respiratory protective equipment (RPE) are the primary controls. Recording that you assessed and controlled this risk is important documentation.

A RAMS document combines the risk assessment with a step-by-step method statement for how the work will be carried out. For tiling work in occupied properties, work with restricted access (compact shower enclosures), or work on sites where another contractor is also present, a RAMS is expected rather than optional.

The method statement section covers:

• The sequence of work: substrate inspection, setting out, adhesive application, tile laying, grouting, sealing.
• Equipment to be used at each stage: wet saw, notched trowel sizes, tile spacers, grout float.
• PPE and RPE required at each stage, particularly dust management during cutting.
• How the work area will be protected (adjacent surfaces, client's property).
• Emergency procedures.

RAMS documents are what larger principal contractors will request before allowing a tiling subcontractor onto their site. Having a template you complete per job is more practical than creating one from scratch each time.

A materials waste log records what materials arrived on site, what was used, and what variance occurred. For tiling, this means tracking:

• Tile quantities ordered and batch reference (batch reference matters because tiles from different batches can have colour variance).
• Adhesive and grout quantities used.
• Actual waste percentage per job (cuts and breakage).
• Any materials returned or carried forward to the next job.

Tile breakage variance is a real factor. Cutting for angles, wet areas, feature rows, and awkward junctions produces off-cuts that cannot be returned. A waste log that records expected versus actual variance, with delivery notes attached, is the defence against a client who disputes that a full box of tiles was legitimately consumed.

The waste log also feeds directly into your quarterly MTD expense records: the materials cost in the period is what you paid for what arrived on site, regardless of what was used versus what was cut.

A systematic photo record of work in progress is one of the most important protections in tiling, because tiling disputes often arise from conditions that were concealed once the tiles went on. For tiling specifically:

• Before any tile-laying begins: photograph the substrate condition in full. Any existing damage, damp patches, out-of-level surfaces, or substrate defects that you have noted or raised with the client should be photographed and documented in writing before you proceed.
• At each milestone stage: photograph the tile layout, adhesive coverage on a removed tile (as evidence of correct adhesive application), and any junction details specified in the scope.
• At completion: photograph finished tiling, grout quality, edge profiles, and any details specified in the scope.
• Any site condition that departs from what was agreed: if the substrate was presented as ready but you identified a problem on the day, photograph it immediately, stop work, and notify the client in writing before proceeding.

Store photos by job reference, backed up to cloud storage. Photos from twelve months ago need to be retrievable if a warranty query arises.

A sign-off document records that the work was completed to the agreed specification and that the client accepted the work. A snag list is the mechanism for handling minor items before sign-off.

The sign-off process for a tiling job:

1. You walk the completed work with the client.
2. Any items the client raises that fall within the agreed scope are noted on the snag list, with a date for resolution.
3. Snagged items are addressed and re-inspected.
4. The client signs a completion document confirming the work was completed to specification and all snagged items resolved.
5. The final payment milestone is then due.

A signed completion document does not eliminate legitimate warranty claims for workmanship defects that appear later. It does significantly narrow the scope for disputes about work the client inspected and accepted at handover.

Your invoice template should record:

• Your business name, address, and contact details.
• Your UTR number (Unique Taxpayer Reference), or company registration number if operating through a limited company.
• The client's name and address.
• The invoice date and a unique invoice number.
• A description of the work the invoice relates to (referenced to the job and the milestone).
• The net amount, VAT if applicable, and the total payable.
• If you operate under CIS and the client is a contractor: the CIS deduction rate that applies (20% for verified subcontractors, 30% for unverified).
• Payment terms and bank details.

Invoice templates that record all of this from the start make both quarterly MTD submissions and year-end accounts faster.

If you bring in another tiler or a labourer to assist on a job, a written sub-contractor agreement matters in two directions. It protects you from their employment status being disputed, and it protects both parties on payment terms.

A sub-contractor agreement should cover:

• The nature of the engagement (self-employed subcontractor, not employee).
• The scope of the work within the job (which areas they are tiling, which surfaces they are responsible for).
• The rate of pay and payment terms.
• CIS status: if both of you are within the CIS, confirm the deduction rate that applies.
• Who supplies tiles, adhesive, and tools.
• What happens if the main client instructs a variation.
• Liability for work quality and rectification if their tiling is defective.
