Think back to the last job that went sour. Odds are the row wasn’t really about the money. It was about whether the money covered the thing being argued over — the skip, the painting, the second coat, moving the old units to the garage. Two people looked at the same price and pictured two different jobs.

That gap has a name. The scope of work is the part of your quote that describes what you’re actually going to do, in enough detail that there’s only one job it could possibly be. It’s the cheapest insurance in the trade: half an hour of writing that removes most of the arguments you’d otherwise have over the following year.

What a scope of work is — and what it isn’t

Your quote does two different jobs, and they get muddled constantly.

The scope of work describes the work: what gets done, to what standard, by whom, with what. Your terms and conditions describe the commercial rules around it: payment, validity, cancellation, guarantees, liability. Terms tell the customer how the deal works. The scope tells them what they’re buying.

You need both, and they belong on the same document. But a beautiful set of terms won’t save you if the scope says “refit kitchen” and the customer thought that included the floor.

A good scope is written from the customer’s side of the fence. They can’t read a materials list and picture the outcome. Tell them what will exist when you drive away — “walls filled, sanded and finished in two coats of your chosen emulsion” — not just “prep and paint”.

The two lists that do most of the work

Inclusions: walk them through the job in order

Write the work as a sequence, in the order you’ll do it. It’s easier for you to check for gaps, and it reads to the customer like someone who’s clearly done this before.

Go one level more specific than feels necessary. “Tiling” becomes “wall tiling to shower enclosure and splashback areas, including adhesive, grout and trims”. “Electrics” becomes “supply and install six downlights, two double sockets and an isolator, including testing and certification”. Vague lines are where disagreements grow. It’s the same discipline as itemising the price rather than sending a lump sum, applied to the words instead of the numbers.

If the job has natural stages, use them as your structure. A bathroom refit reads far better as strip-out, first fix, tanking, tiling, second fix and making good than as one paragraph.

Exclusions: short, specific, and about your jobs

Exclusions are the list most trades either skip entirely or pad out with generic filler. Neither works. You want a handful of lines covering the things that genuinely come up on your jobs, in your trade, phrased plainly.

The usual suspects worth a look:

Waste removal, skip hire and permits
Scaffolding, towers and access equipment
Decoration and making good after the work
Builder’s work — chasing, lifting floors, cutting away, reinstating plaster
Asbestos surveys or removal, and any specialist testing
Structural or damp works uncovered once you’re in
Parking charges, permits and congestion or clean-air fees
Appliance supply, connection or commissioning
Out-of-hours or weekend working

Only list what’s realistically in play. Ten relevant exclusions beat forty copied off the internet, because the customer will actually read ten.

Write down your assumptions

Every price rests on things being as they appeared on survey. Assumptions are those conditions, written down, so that if one turns out to be wrong you’ve got a fair basis for a conversation rather than an accusation.

Useful ones to state:

The property will be empty of furniture and belongings in the working areas
Existing services are sound, accessible and correctly installed
The substrate is level and suitable for the specified finish
Power, water and welfare facilities are available on site
The work can be carried out in one continuous visit
Drawings, specifications or customer selections are final at the date of the quote

Where an assumption is doing a lot of heavy lifting — a floor you can’t see, a wall you can’t open up — that’s a signal the job may not suit a firm price at all. A range, a provisional sum or a “subject to opening up” caveat is more honest, and the difference between a quote and an estimate is worth being precise about on the document itself.

Who supplies what, and to what standard

Two lines here save an enormous amount of grief.

Supply. Say explicitly who is buying the materials, fittings and appliances. Where the customer supplies something, note that lead times, shortfalls, breakages and suitability sit with them, and that a late delivery may move your dates. Sourcing is real work, which is why it belongs in how you price and mark up materials as well as in the scope.

Standard. Name the finish rather than implying it. Which paint, how many coats, which grade of board, what tolerance, which regulations and manufacturer instructions you’re working to. “Plaster to a smooth finish ready for decoration” and “plaster to a polished finish” are different amounts of work, and the customer imagining the second while paying for the first is a dispute in waiting.

Access, hours and the practical stuff

Not glamorous, but it’s where days quietly disappear:

The dates or duration, and the hours you’ll be working
Where you’ll park, unload and store materials
Which areas you need clear, and by when
Whether pets, children or other trades will be on site
Who holds the key and how you get in
What protection you’ll put down, and what condition you’ll leave the site in each day

The change process, agreed in advance

Scope changes. Customers add things, and walls hide things. What causes disputes isn’t the change — it’s changing the work without agreeing the price first.

Put one plain line in the scope: any addition or alteration to the work described, whether requested by the customer or arising once work is underway, will be priced and agreed in writing before it’s carried out. Then hold to it, including for the small stuff. The £60 favour you absorb without a word is the precedent that makes the £600 one awkward.

Agreeing it in advance also takes the awkwardness out of the moment it matters. You’re not haggling — you’re following the process you both signed up to.

Get it signed off before you start

A scope only works if the customer has genuinely read and accepted it. That means:

It goes out with the quote, not afterwards — same document, same conversation.
You walk them through it and pause on anything that changes the price.
Acceptance comes back in writing. A text saying “yes, happy with that, go ahead” is a perfectly good record. A phone call isn’t, unless you follow it with a short email confirming what was agreed.
Any change gets the same treatment — priced, written, agreed, then done.

A scope block you can adapt

Scope of works — [job address]

We will: [numbered list of the work, in the order it will be carried out, with finishes and standards named.]

Not included: [your genuine exclusions — waste, scaffolding, making good, builder’s work, and so on.]

Supplied by us: [list.] Supplied by the customer: [list.] Customer-supplied items are subject to their own lead times and suitability.

This price assumes: [your key assumptions about access, condition and site.]

Access and dates: [working hours, duration, parking, areas to be cleared.]

Changes: Any work outside the above will be priced and agreed in writing before it is carried out.

Keep it to a page and write it like you talk. A scope nobody reads protects nobody.

The takeaway

Disputes don’t usually start with a bad customer. They start with a sentence that was clear to you and ambiguous to them.

Describe the work in sequence, list the exclusions that actually apply to your jobs, write down what you’re assuming, name who supplies what and to what standard, and agree the change process before you need it. Then get it accepted in writing. You’ll spend half an hour more on each quote and lose far fewer weekends to arguments about what “included” meant.

Queezy builds the scope as you survey — room by room, task by task — so the itemised PDF the customer accepts is the same detail you priced from. Join the waiting list for early access.
