Retrofit coordinator insurance is the professional indemnity and liability cover needed by retrofit coordinators, assessors, designers and evaluators working to PAS 2035. The most important cover is professional indemnity, which protects you if a client or homeowner claims your assessment, risk grading, measure selection or design was wrong and led to damage or extra cost. Coordinators also need public liability for site visits and employers' liability if they employ staff. Because retrofit errors such as unsuitable insulation or poor ventilation can cause damp and mould years later, insurers want to understand exactly what you sign off, how you assess risk and whether you rely on others' work. TrustMark and scheme requirements often set minimum PI limits.

Working as a retrofit coordinator or assessor? We'll arrange PI that reflects the decisions you actually make.

Key facts at a glance

  1. PI is the core cover. Your risk is in advice and sign-off, not physical work.
  2. Defects appear late. Damp and mould from poor measure choice can surface years afterwards.
  3. Claims-made cover needs continuity. Let PI lapse and later claims may not be covered.
  4. Scheme rules set limits. Certification bodies and contracts often specify minimum PI.
  5. Scope must be declared. Coordinating, assessing and designing are rated differently.

What insurance does a retrofit coordinator need?

Professional indemnity is essential, alongside public liability and employers' liability where you employ staff.

CoverWhat it protectsWatch out for
Professional indemnityClaims for errors in assessment, design and sign-offExclusions for specific measures or building types
Public liabilityDamage or injury during site visitsUsually low risk, but still needed
Employers' liabilityInjuries to staffA legal requirement once you employ anyone
CyberLoss of client data and property recordsHomeowner personal data
Run-off coverClaims after you stop tradingEssential with claims-made PI

Installers carrying out the work need a different programme, set out on our retrofit and insulation installer insurance page.

Why is retrofit PI a specialist risk?

A retrofit coordinator signs off on the overall plan for a home. If measures interact badly, for example insulation without enough ventilation, the coordinator may be blamed for the damp that follows.

PAS 2035 puts the coordinator at the centre of the process, responsible for assessment, the medium-term improvement plan, design oversight and evaluation. That's a lot of responsibility, and it means claims could come from homeowners, social landlords or installers. Insurers want to know what you do yourself, what you rely on others for, and how you document your decisions.

Check what your PI excludes

Some PI policies exclude certain insulation types, listed buildings or properties with known defects. Make sure the wording fits the work you actually coordinate.

What do insurers ask a retrofit coordinator?

Insurers want to understand your roles, your clients and your processes.

  • Roles. Coordinator, assessor, designer or evaluator
  • Qualifications. Relevant retrofit qualifications and experience
  • Clients. Homeowners, social landlords, installers or scheme managers
  • Schemes. Government-funded or private work
  • Fees. Fee income and the size of the largest projects
  • Processes. How assessments and sign-offs are recorded
  • Contracts. Liability caps and indemnities you give

How can coordinators manage their risk?

  1. Document every decision. Keep assessment and design records.
  2. Define your scope. Be clear in contracts about what you do and don't do.
  3. Cap liability where possible. Negotiate sensible limits.
  4. Keep PI continuous. Arrange run-off if you stop trading.
  5. Stay qualified. Keep training and certifications current.

Where the information comes from

Our articles are compiled from a range of sources: regulators and public bodies such as the FCA, the Civil Aviation Authority, the Health and Safety Executive and Companies House; government publications and legislation; industry and trade bodies; insurer and market documentation; and published research and news reporting. Not everything stated originates from Miller & Partner. Where information comes from a third party we believe it to be accurate at the date of publication, but we haven't independently verified every external source and we don't warrant its accuracy or completeness. Where a point matters to a decision you're making, go to the original source and check it.

Figures, examples and case studies

Premium ranges, cost figures, limits and worked examples are illustrative only. They are not quotations, not offers of cover, and no cover is provided or implied on the basis of them. What you're actually charged depends on underwriting, and what you're actually covered for depends on the policy wording issued to you. Where an article includes a claim example, scenario or case study, it is illustrative unless we say otherwise — such examples are typically composites written to show how a policy section responds, and they don't describe an identifiable client, claim or settlement.

Interactive tools

Any calculators, cover checkers, risk assessors or similar tools on our site produce general guidance from the small number of answers you give them. They can't see your business, and their output is not a personal recommendation, an assessment of your actual risk, or a quotation.

Rules and market conditions change

Law, regulation, tax treatment, insurer appetite and policy wordings all change, sometimes at short notice. Content is accurate to the best of our knowledge on the date shown on the article and we don't undertake to update it as things move. An article you're reading some time after publication may be out of date.

Third parties and external links

References to insurers, underwriters, trade bodies, software, training providers or other organisations are for information only. They don't imply endorsement, recommendation, partnership or affiliation in either direction unless stated. We're not responsible for the content of external websites we link to.

Not legal, tax or accounting advice

Nothing here is legal, tax, accounting or regulatory advice. Where an article discusses statutory duties, contract terms or compliance obligations, take advice from an appropriately qualified professional on your own position before acting.
