The InsulationMatch installation standard

Before work

Where relevant, the survey and specification consider:

• existing construction
• roof and loft condition
• ventilation
• moisture
• existing insulation
• access
• services
• intended room or loft use
• system specification, with the product certificate and target U-value stated

During work

Recorded where appropriate, in photographs and notes:

• product and system
• build-up
• joints
• fixing
• tapes
• interfaces with walls, dormers and eaves
• penetrations
• ventilation routes
• relevant air gaps

Completion

Retained for every project:

• completion photographs
• project information
• product information where applicable
• customer handover notes
• issue and escalation record if required

What every installer agrees to

Before joining

• Public liability insurance of at least £2 million, evidenced and kept current
• Registered with a relevant competent person or certification scheme for the measures they quote, and scheme-registered where funded work is offered
• A trading history we can verify and trade references checked
• No unresolved adverse findings with Trading Standards or the Advertising Standards Authority

Every quote must

• State the area in m², the materials, thicknesses and the U-value the build-up achieves
• Show the ventilation strategy for any roof or floor work
• State whether the work is notifiable and who handles building control
• Include a written workmanship guarantee and the relevant product or scheme guarantee
• Be free, in writing and valid for at least 30 days

Conduct

• Contact the homeowner about their enquiry only; no unrelated marketing
• No pressure tactics, no same-day-only pricing, no claims about grant eligibility that have not been verified
• Recommend the cheaper material where it does the same job
• Respond to a matched enquiry within two working days

If it goes wrong

Tell us. We investigate, and installers who breach the standard are removed from the network.
