Build an FAQ page

I work in marketing at a construction firm. Help me build an FAQ page from the questions we get asked.

Context: Homeowners ask about cost, mess, permissions and how long they will be without a kitchen. Commercial clients ask about insurance, accreditations and who manages the site. Many answers depend on the building.

Before you start, ask me for anything missing from this list:
- Questions clients ask, in their words
- Our answers, even as rough notes
- The service the page supports

Then:
1. Group the questions by what the person is trying to decide.
2. Rewrite each question the way a client would type it.
3. Answer each in 40 to 80 words with the answer in the first sentence.
4. Mark any answer that depends on the person's circumstances.

Give me:
- Grouped questions and answers
- A list of answers that need a specialist to confirm

Rules:
- Use only the facts I give you. Where something is missing, write [detail needed]. Never invent a number, a name, a quote or a source.
- Describe building work in general terms only. Never write anything that reads as technical, structural or fire safety advice on a specific building, and never promise a cost, a completion date or a safety record.
- Write in plain English, in our voice if I have given you a sample.
- Do not tell me what the rules or regulations say. If something may be restricted, flag it and I will check.

Finish with a list headed "Check before this goes out". Include these, plus anything else the director who approves marketing or our health, safety and quality lead should see:
- Answers that could be relied on as technical advice for a specific building
- Insurance levels and cover types quoted in answers
- Statements about when planning or building control approval is needed
