Trade case · Insulation
Insulation is priced per square metre, not per evening
Blown loft insulation, internal wall linings, energy-efficiency renovation: large surfaces, a reduced VAT rate to apply correctly, and customers who need a quote precise enough for their funding file. MaitreChantier prices the square metres and produces the document that goes with them.
Your day-to-day, point by point
The situations that eat your evenings — and what the platform does about each of them.
Today
The reduced rate applies to the insulation, not to everything
With MaitreChantier
The rate belongs to the line: 5.5 % on the eligible work, 10 % on the removal or the extras, with the base shown per rate.
Today
The customer's funding file wants surfaces, materials and performance
With MaitreChantier
Each line takes a description — thickness, thermal resistance, material — and it stays on the PDF the customer forwards.
Today
Large surfaces, small margin per square metre
With MaitreChantier
Your cost price sits behind each work: on two hundred square metres, you see immediately what a two-euro discount costs you.
Today
Quotes wait weeks for a decision
With MaitreChantier
Sent, signed, refused, expired: the status of every quote is visible, so a pending one gets a call rather than being forgotten.
What you gain, every week
Reduced rate where it belongs
5.5 % on the eligible work and 10 % on the rest, on the same quote, with a breakdown the customer can check.
Priced per square metre
Lofts, walls, floors: enter the surface, the line prices itself with your own rate and your cost price.
Descriptions that survive to the PDF
Thickness, thermal resistance, material: written once under the line, printed on the quote and on the invoice.
Quotes followed until the answer
Sent, signed, refused, expired: you know which quotes are still worth a phone call.
Margin over large surfaces
Material purchases and hours are booked against the job, so the rate per square metre is checked against reality.
Deposit, then balance
Invoice a deposit on signature and the balance on completion, with the amounts already invoiced deducted.
What an insulation quote looks like
An extract from an energy-efficiency renovation: eligible work at 5.5 %, removal at 10 %.
| Description | Qty | Unit price | VAT | Total excl. VAT |
|---|---|---|---|---|
| Blown loft insulation, 32 cm (R = 7 m².K/W) | 120 m² | €38.00 | 5.5 % | €4,560.00 |
| Internal wall insulation (lining) | 65 m² | €56.00 | 5.5 % | €3,640.00 |
| Removal and disposal of the old insulation | 120 m² | €12.00 | 10 % | €1,440.00 |
| Total excl. VAT | €9,640.00 | |||
Two rates, one document: the VAT base is shown per rate, and the descriptions follow onto the invoice.
The detail your client's file asks for
Every line carries its description: thermal resistance, thickness, treated surface. The client has the detail in front of them, and you rewrite nothing.
How it goes, from quote to payment
Price the surfaces
Loft, walls, floors: take the works from the library, enter the square metres, describe the material and the performance.
Follow the decision
The quote is sent, then waits for a funding decision: its status tells you when to call back rather than when to hope.
Insulate, then invoice
Deposit on signature, balance on completion, purchases booked against the job — the margin per square metre stays visible.
Frequently asked questions
- Can I apply 5.5 % only to the eligible lines?
- Yes: the rate is set line by line, and the document shows the taxable base for each rate.
- Can the quote carry the technical detail my customer needs?
- Each line takes a free description — thickness, thermal resistance, material — printed on the quote and on the invoice.
- My quotes wait weeks. Do I have to track them myself?
- Quotes carry a status — sent, signed, refused, expired — so the pending ones stay in front of you.
