What Is a Schedule of Works? A Guide for Renovation Clients
In short
A schedule of works is a written list of every task in a building project, room by room or trade by trade, with the materials and standard expected. It turns a design into a clear scope that contractors price against, so quotes can be compared fairly and nothing is left open to interpretation.
A schedule of works is the document that says exactly what will be done to your home. Drawings show what the finished space should look like. The schedule explains how it gets there: what is stripped out, what is built, which services are moved, what is supplied by whom and to what standard it is finished. On any renovation of real value, it is the single most useful document you can have before you sign a contract.
What a good schedule of works includes
A schedule is usually set out room by room for a refurbishment, or by trade for structural work such as an extension. Either way, each line should be specific enough that two contractors would price the same thing. A useful schedule covers:
- Preliminaries: site protection, skips, scaffolding, temporary works, welfare, insurance and project management.
- Strip out and demolition: what is removed, what is kept and what is protected.
- Structural work: new openings, steel beams, foundations and anything the structural engineer has specified.
- Services: plumbing, heating, electrics, ventilation and data, split into first fix and second fix.
- Finishes: plastering, joinery, tiling, flooring, decorating and ironmongery, with the products or a clear specification.
- Who supplies what: items the client chooses (often tiles, sanitaryware or a kitchen) shown as provisional sums or client supplied.
- Exclusions: anything not included, written down rather than assumed.
Why it matters for your budget
Most disputes on renovation projects come from a scope that was never written down. If one quote says “renovate bathroom” and another lists forty separate tasks, the cheaper number is rarely the cheaper job. A schedule of works puts every contractor on the same footing, so the comparison is between quality, programme and price for the same work.
It also protects you once work starts. If something is on the schedule, it is in the price. If you change your mind, the change is measured against the schedule and agreed as a variation before it is carried out, rather than appearing as a surprise on the final account.
Who writes it
On larger projects an architect or surveyor often prepares the schedule as part of the tender package. On many London home renovations, the main contractor writes it after a detailed site visit, working from the drawings and your brief. Whoever writes it, read it line by line. If a finish, a fitting or a room is missing, raise it before the contract is signed. The provisional sums in the schedule deserve particular attention, because they are allowances rather than fixed prices.
How it links to the rest of the project
The schedule of works feeds the programme (the order and timing of each stage), the payment schedule and, at the end, the snagging list. When every party works from the same written scope, handover is a check against an agreed list rather than a debate about what was promised.
How we handle the schedule of works on London’s Prestige projects
Every quotation we issue is built on a written, itemised schedule of works prepared after a site visit. You see each task, the specification behind it and anything that is a provisional sum, so you know exactly what you are paying for. During the project, your single point of contact works from the same document, and any change is priced and agreed in writing before it goes ahead. You can see the level of detail this produces on our Hanover Place full house renovation, and read more about our full house renovation service. If you are comparing quotes for work across London, we are happy to visit and talk the scope through with you.
Common questions
Is a schedule of works the same as a quote?
No. The schedule lists the work; the quote prices it. A strong quotation is built on a schedule, line by line, so you can see what each part of the job costs and what is excluded.
Do I need a schedule of works for a small project?
Even a single bathroom benefits from one. A short schedule of twenty or thirty lines makes it clear what is included, from strip out and waterproofing to tiling, fittings and making good.
Can the schedule of works change during the project?
Yes, but changes should be recorded as variations, priced and agreed in writing before the work is done. That keeps the budget and the programme under control.
