Choosing a contractor and comparing quotations: what to look for

Choosing a contractor is not something you do on price alone. Two quotations with different amounts often do not describe the same work. One includes the finishing, the other puts it in a provisional sum. So first compare exactly what is being delivered, and only then the price. Also look at the schedule, the arrangements for extra work, the payment terms and who your point of contact is during the build. With a few targeted questions you quickly see which contractor suits your plan and budget.

How do you compare contractors' quotations fairly?

Make sure every contractor prices the same plan. Pass on the same drawings, the same wishes and the same finish. Ask for a quotation with a clear description per item, so you can put the items side by side.

Then list the differences. If something is included by one and not by the other, ask why. A low price that consists mainly of omitted items still becomes expensive during the build.

• Same drawings and wishes for every contractor
• A description per item, not just a total
• Clear about what is and is not included
• VAT shown separately and applied correctly

What should you watch with provisional sums and extra work?

A provisional sum is a provisional amount for something that has not been chosen yet. Provisional sums that are too low make a quotation look more attractive than it is. In building materials are getting more expensive we explain how provisional sums work and how to deal with them.

Extra work is work that is added during the build. Agree in advance how it will be priced and that it will only be carried out after your approval. That way you keep a grip on the budget.

Choosing a contractor: which questions do you ask?

Ask who carries out the work and who your point of contact is. At Bouwbedrijf R. Vlieland the same project manager oversees all the work, from discussing your wishes to completion. That continuity prevents information from getting lost along the way.

Also ask about previous work similar to your plan, and read reviews. On our projects page you can see what we have built. You can read more about how we work on our about us page.

• Who is my fixed point of contact during the build?
• Who arranges drawings, structural engineer and permit?
• What does the schedule look like, and what if there is a delay?
• How are the payment instalments divided?
• How do you handle extra work and changes?

How do you assess the price in a quotation?

Compare the price with rough market ranges, such as in what does a renovation cost. If one quotation is much lower than the rest, look extra carefully at what is missing. If it is higher, ask what extra is included.

Also pay attention to VAT. For renovation, 21% generally applies to labour and materials, with a reduced rate on labour for insulation work in homes older than two years. See renovation and VAT.

What should the agreement with the contractor include?

A good agreement describes the work, the price, the provisional sums, the schedule, the payment instalments and the arrangements for extra work. Pay in instalments that match progress, and never the larger part up front.

Also check the validity of the quotation and whether it contains a price escalation clause. If you are unsure about any point, ask before you sign. A contractor who explains things calmly is usually easy to reach during the build as well.
