Air Conditioning Quote Wizard Development

PROJECT TITLE

Custom Secure Air Conditioning Instant Quote Wizard (With Postcode + SMS Verification)

⸻
PROJECT DESCRIPTION

I am the director of WDI Group (Surrey) Ltd, a UK-based plumbing, heating and air conditioning company.

I am looking to build a custom, embeddable air conditioning instant quote wizard for my website.

This must be a professional, secure, step-by-step quoting tool that:

• Validates postcode before proceeding
• Collects installation details
• Calculates pricing dynamically (logic provided by me)
• Requires SMS or email verification BEFORE revealing the price
• Displays estimated price range only after verification
• Sends all lead details to me via email
• Includes an admin dashboard to edit pricing rules
• Is fully owned by me (no SaaS subscription platform)

This tool must be embeddable into my existing website via iframe or script.

⸻
REQUIRED USER FLOW

Step 1 – Postcode Validation

User enters postcode.

System checks against allowed postcode prefixes:
SM, CR, KT, RH, SW, GU, BN, TW, BR, SE

If outside coverage area → polite exit message.

⸻

Step 2 – Installation Questions (Wizard Style UI)

Step-by-step interface collecting:

• Property type
• Number of rooms
• Room sizes
• Installation type
• Pipe run length
• Outdoor unit position
• Optional upgrades (WiFi, premium brand, etc.)

Pricing must calculate in background but NOT be shown yet.

⸻

Step 3 – Lead Capture & Verification

User enters:

• Full name
• Email
• Mobile number

System sends:

• SMS verification code (preferred via Twilio or similar)
OR
• Email verification link

User must verify before proceeding.

No verification = no price shown.

⸻

Step 4 – Price Reveal

After successful verification:

Display:

“Estimated Installation Cost: £X – £X”

Include note:
“Final price confirmed following free site survey.”

No detailed breakdown required.

⸻

Step 5 – Survey Booking CTA

After price display:

Button:
“Book My Free Survey”

This can either:
• Trigger email notification
• Open booking request form
• Or integrate with calendar system (optional enhancement)
