Find projects before they reach tender sites
By the time a homeowner posts publicly for quotes, several builders may already be competing. Planning applications reveal intent earlier, especially for extensions, loft conversions and outbuildings.
Make outreach useful, not pushy
The best first message feels timely and specific. Reference the type of work, explain relevant experience, and make it easy for the homeowner to ask for advice or a quote.
- Mention similar extension work you have completed nearby.
- Offer a short planning-to-build checklist.
- Avoid scare tactics or exaggerated claims.
Follow up around decision milestones
An application being submitted, validated, approved or refused creates different needs. Saved-search alerts help builders follow up when the applicant is most likely to be planning the next step.

Frequently asked questions
When should a builder contact someone about an extension?
The most useful points are after validation, around approval, or after a refusal if you can help redesign or re-scope the project.
What should a builder include in a first outreach letter?
Include who you are, why the proposed work is relevant to your experience, local proof, a simple next step and a clear way not to be contacted again.
Do planning leads replace referrals?
No. Planning leads complement referrals by giving builders a reliable way to find high-intent local projects before they are widely advertised.
