How to hire a plumber in Sweden: complete checklist 2026
How to hire the right plumber in Sweden in 2026, checklist for Säker Vatten, F-skatt, insurance, quotes and contracts.
Hiring the wrong plumber costs more than the job itself. Cheating on certifications leads to insurance problems and may force the condo association to demand the job be redone.
Here's the complete checklist to pick the right plumber in 2026, from pre-booking checks to how to avoid invoice disputes.
Step 1, Pre-booking checks
- Säker Vatten authorization (sakervatten.se), mandatory for wet-room work.
- F-skatt certificate at Skatteverket, shows the company is authorized to invoice.
- Liability insurance with at least 10 million SEK cover.
- Company has been active at least 2 years (check via allabolag.se).
- Reviews on more than one platform.
Step 2, Request quotes the right way
Send the same description and photos to at least 3 firms. Be specific: home type, age, address, problem description, desired start date.
Insist on an itemized quote with labour, materials, call-out and ROT listed separately. Verbal quotes are not binding.
Step 3, Read the quote critically
- What's included and what's not?
- Fixed price or hourly? If hourly, what's the ceiling?
- What happens if extra work is discovered?
- Payment terms, late payment ok, deposit rare.
- Warranty on the work (at least 2 years, ideally 5).
Step 4, Contract and start
Write a contract even for small jobs. Simple SMS contract with scope, price and start date is enough for small jobs; bigger jobs need written.
Check the tradesperson's ID when they arrive. Photograph the van with company logo for your own records.
Step 5, During and after the job
Protect floors and furniture. Insist the work is documented with photos, especially things hidden behind walls or under floors.
When the job is done, walk through together before you sign. Check everything works and nothing leaks after an hour.
Step 6, Invoice and ROT
Insist on an itemized invoice with labour and materials listed separately. The ROT deduction must be applied directly on the invoice.
Never pay cash, you lose ROT and have no evidence in a dispute.
