Scope of Works for Tradesmen - What to Include and Why

Disputes between tradesmen and customers almost always come down to one thing: what was included in the agreed price. A clearly written scope of works is the document that prevents those disputes - before the job starts, not after.

What is a scope of works?

A scope of works is a written description of exactly what a job includes, what it excludes, and under what conditions. It forms part of your quote - when a customer accepts your quote, they are accepting the scope of works along with the price.

For small jobs, the scope is a few lines in your quote. For larger jobs - extensions, full rewires, bathroom or kitchen renovations - it should be more detailed.

Why you need one on every job

The scope of works protects you against:

• Scope creep - customers adding work mid-job that was never in the original price
• Inclusion disputes - “I thought that covered the tiling too”
• Unforeseen conditions - “The price didn't include what was behind the wall”
• Return visit arguments - “You need to come back and fix this” when it was explicitly excluded

What to include in a scope of works

The exact location

State the full address and, if relevant, which room or part of the property the scope applies to. If you are doing multiple jobs at the same property under separate quotes, make this explicit.

A clear job description

Write in plain English what you will do. Not “bathroom renovation” but “strip out existing suite, remove tiles, install new basin and WC, shower tray and enclosure, tile walls to 2m height, seal and grout.” The more specific, the more protection you have.

Materials specified by name or grade

If specific materials are included, name them or name the specification: “Ideal Logic 30kW combi or equivalent,” “50mm Kingspan insulation board.” This prevents later disagreements about what was supplied.

Explicit exclusions

List what is not included. Examples by trade:

• Plumber: all electrical work, gas connections (if not Gas Safe / RGII registered), decorating
• Electrician: all plumbing, structural alterations, decorating after containment fitting
• Builder / roofer: lead valleys (if not in scope), guttering, structural timber repair
• General: scaffolding (if not included), skip hire, decorating, plastering

Unforeseen work clause

Include a clear statement that unforeseen conditions (rot, asbestos, structural issues, concealed damage) will be reported immediately and quoted separately before work proceeds. This is standard and customers expect it.

Customer responsibilities

What does the customer need to provide or arrange? Clear access and parking, rooms emptied before start, tiles ordered and on site, specific decisions made before day one. Delays caused by the customer are not your responsibility - and the scope makes that clear.

A scope of works example: bathroom renovation

Location: Main bathroom, [address]

Scope: Strip existing suite (bath, basin, WC). Remove and dispose of existing floor tiles and wall tiles. Install new Roca Debba back-to-wall WC and wall-mounted basin, Mira Select EP 900mm shower enclosure and tray. Replumb hot and cold supplies. Tile walls to 2.1m height using customer-supplied tiles. Tile floor using customer-supplied floor tiles. Grout, seal, and silicone all joints. 2.5 days labour.

Excludes: All electrical work including heated towel rail connection. Decorating. Plastering. Supply of tiles or tile adhesive. Structural or timber work. Any mastic-only repair to pipe runs outside the bathroom.

Unforeseen: Any concealed damage, rot, or structural issues found during strip-out will be reported immediately and quoted separately before work continues.

Customer to provide: Tiles and tile adhesive on site before start date. Clear access. Parking for van.

How to handle scope changes during the job

When a customer asks for something that was not in the original scope:

1. Quote for the additional work separately and get written agreement before doing it
2. A WhatsApp message is sufficient: “Happy to add the towel rail installation for €150 + VAT - shall I proceed?” and a reply of “yes” is an enforceable agreement
3. Do not do extra work and hope the customer will pay for it later

Never do unquoted work without written confirmation of the price. That confirmation, however informal, becomes part of the contract.

How PayReady handles scope of works

In PayReady, the job description you write when creating a quote becomes the scope of works. It is stored against the job, visible to you and your customer through the public client link. When you convert the quote to an invoice, the description carries across automatically.
