Rewrite the homepage

I work in marketing at a construction firm. Help me rewrite our homepage so a stranger understands us in ten seconds.

Context: A visitor decides in seconds whether this firm builds their kind of project at their kind of size, and whether it looks safe, solvent and competent to work with.

Before you start, ask me for anything missing from this list:
- The current homepage text
- Who we most want to hear from
- What makes us different, with proof

Then:
1. Write a headline that says who we help and with what.
2. Follow with three short proof points.
3. Cut anything any competitor could also say.

Give me:
- Headline and sub-headline
- Section-by-section copy
- A list of what you cut and why

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:
- Accreditation and scheme logos, each currently held and used as licensed
- Claims such as award-winning, leading or carbon neutral, with their basis
- Project counts, values and 'on time, on budget' figures
