Help during a building project
If work has already started and you are unsure about a payment, a change, a delay or the quality of what you are seeing, you are in the right place. The Construction Clinic helps homeowners understand the decisions in front of them, ask better questions and know when it is sensible to pause before approving money, changes or final handover.
You are not expected to know everything about construction
Building work asks homeowners to make high-value decisions in unfamiliar language, often quickly and often on site. Not knowing what a provisional sum is, or whether a payment request is reasonable, is not a failing. It simply means no one has explained the process in plain English.
Most difficulty in a project comes from meeting a stage unprepared, not from bad intentions. A clearer understanding of what is normal, what should be written down and what deserves a second look tends to settle both the project and the relationship with your builder.
Common issues homeowners ask about during a build
A payment request I do not fully understand
Stage payments, deposits for materials or an invoice that does not match the original quote.
A change to the works
A variation, an unexpected extra or a specification that has quietly moved on site.
Progress that feels slow or unclear
Quiet weeks, missing trades or no updated programme to check against.
Quality that does not feel right
Finishes, tolerances or workmanship you are unsure how to assess or raise.
Communication that has broken down
Difficult conversations, defensive responses or decisions being made without you.
Approaching completion
Snagging, final payment, certificates, warranties and what happens after handover.

What to check before approving a payment
- The work described has actually been completed on site to that stage.
- The amount matches the agreed payment schedule or a documented variation.
- You are not paying materially ahead of the work in place.
- Any materials paid for in advance are identified and accounted for.
- You have the invoice in writing, with a breakdown you can follow.
What to do when a builder asks for a variation
A variation is a change to what was agreed. It may be entirely reasonable — conditions on site are rarely fully known up front. What matters is that it is defined before it happens.
- Ask what is changing and why, in writing.
- Ask for the cost effect, including any credit for work no longer required.
- Ask for the effect on the programme.
- Agree it before the work proceeds, not after it appears on an invoice.
What to do if work feels delayed or unclear
Ask for a revised programme with the reason for the delay and new key dates. Agree a simple rhythm of updates — a short weekly written summary is usually enough. Keep a dated record of what was said and agreed. Delay itself is common; unexplained delay is the part worth addressing early and calmly.
What to check before final payment, snagging and handover
- A written snagging list, agreed with dates for completion.
- Certificates, sign-offs and warranties collected and stored.
- Operating and maintenance information for anything installed.
- Outstanding items resolved or formally accounted for before final release.
- A clear understanding of what aftercare and defects cover you have.

Common questions
Questions homeowners ask mid-project
What should I do if my builder asks for more money?
Ask what the extra cost is for, whether it is a variation to the agreed works or a correction to the original quote, and request it in writing with a breakdown. Compare it to your original quote and payment schedule before agreeing. It is reasonable to pause and ask questions before approving any additional cost.
Should I approve a variation during building work?
Only once you understand what is changing, why it is needed, what it costs, and how it affects the programme. A variation should be written down and agreed before the work happens, not discovered later on an invoice.
What should I check before paying a builder?
Check that the work you are paying for has actually been completed to the stage described, that the amount matches your agreed payment schedule, that any variations are documented, and that you are not paying significantly ahead of the work on site.
What should I do if my project is delayed?
Ask for a revised programme in writing with the reason for the delay and the new key dates. Delays are common and often reasonable, but they should be explained, dated and tracked rather than left vague.
What should I check before final payment?
Walk the property and record a snagging list, confirm outstanding items and dates for completing them, collect certificates, warranties and handover documents, and only release the final payment once the agreed items are resolved or formally accounted for.
Can The Construction Clinic help if I am already on site?
Yes. Most homeowners come to us mid-project. The Clinic helps you understand where you are in the process, what a decision actually involves, and which questions to ask your builder or professional team before you approve money, changes or handover.
