Check ad copy before it runs

I work in marketing at a construction firm. Help me check this ad copy before it goes live.

Context: Construction advertising attracts complaints when it overstates accreditations, promises a price or a finish date, or makes green claims without evidence behind them.

Before you start, ask me for anything missing from this list:
- The ad copy
- Where it will run
- Our house rules for advertising

Then:
1. List every claim.
2. Sort each as fine, needs evidence, needs sign-off, or remove.
3. Offer a safer wording that keeps the selling point.

Give me:
- A verdict
- Claims to sort out with safer wording
- What is missing

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, membership and approved-installer claims
- Price, timescale and guarantee wording, and its terms
- Environmental and energy-saving claims, with the evidence for each
