Short answer & context
This page deliberately answers a narrowly defined planning question. It connects the specific configuration with a checklist so quotations, authority guidance and technical decisions are not mixed together.
Insurance timing depends on the construction phase and risk. Builder liability, construction/fire shell cover and the later building insurance serve different purposes and should not be treated as interchangeable products.
Check cover, not just the product name
Focus on insured events, exclusions, excess, construction period, self-build work, helpers, outbuildings, PV/heat pump and the transition to permanent building cover. Terms differ between insurers, so this guide is not a tariff comparison or individual recommendation.
Decision in 5 steps
- Define the goal, site and scope in writing.
- Mark missing documents and assumptions.
- Calculate or quote at least two comparable variants.
- Verify dynamic items such as rates, funding, tariffs or local law at the current date.
- Document the decision, source and date.

The table is not a substitute for design documents. It works as a cover sheet for comparing quotations and decisions: when one parameter changes, record which costs, technical evidence, deadlines or permission questions change with it.
Current 2026 context
Insurance terms are contractual and can differ materially between providers. For self-build work, helpers, PV, heat pumps, natural hazards or long construction periods, do not infer cover from the product name. The application, wording, insured amount, exclusions and documented risk features control.
Document and quotation checklist
- Current drawing/design revision with date and version.
- Specification with clear included and excluded work.
- Quantities, quality level, products or technically equivalent requirements.
- Interfaces with plot, foundation, building services and external works.
- Price date, validity, payment schedule and variation rules.
- Open authority, funding, finance or insurance questions with owner and deadline.
- Differences between quotation, contract, selections and later change requests.
The more complex the project, the more useful an independent review by the appropriate professional becomes. Ideally that review happens before a binding signature, not only after a dispute has arisen.
Avoid common mistakes
Planning contingency is not wasted budget. It prevents each unexpected detail from immediately changing finance or schedule.
- Treating brochure price as total project cost.
- Assuming unclear work is included.
- Using outdated funding, legal or price information without checking.
- Approving changes without a revised plan and cost impact.
Frequently asked questions
Are the figures a quotation?
No. Figures and graphics are for orientation. Real prices, finance, insurance, permission and technical design depend on the project and current conditions.
Why show sources and update dates?
Construction prices, funding, rates, tax rules and legal requirements can change. Sources and dates help identify outdated assumptions.
What should I do next?
Cross-check the open checklist items against plot documents, supplier quotation, authority guidance or the responsible professional and record the answers.
Is this individual professional advice?
No. Legal, tax, finance and insurance decisions in particular require case-specific checking by an appropriately qualified party.
