Before you get in touch
How to choose a builder in Jersey
Jersey has its own building rules, and many UK terms, from the Party Wall Act to CDM, don’t apply here. These are the checks that do.
There’s no register of approved builders
The Government of Jersey’s list of industry licences (opens in a new tab) has none for builders. A business licence controls who can run a business and employ staff, not the quality of the work. The Jersey Construction Council (opens in a new tab) is the industry body, and its membership is open to anyone in the trade.
So the checks are down to you: ask to see recent jobs on the island, speak to past customers, and get more than one quote for anything sizeable.
Planning and bye-law permission are separate
Planning permission covers what you build and how it looks. Building bye-law permission covers how it’s built, such as structure and fire safety. Most extensions need both, and some smaller jobs need neither under the General Development Order. Agree in writing who is applying for which permission before work starts. Our architects page explains the planning side in more detail.
Inspections and the completion certificate
Where bye-law permission is needed, a building control surveyor inspects the work at set stages (opens in a new tab), from foundations and drains to the roof and completion, and not giving notice at those stages is an offence. When everything has passed, the department issues a completion certificate (opens in a new tab), which it calls an important record to keep. Ask for it at the end, along with the certificates for any windows, electrics or heating fitted under a competent person scheme.
Who’s responsible for safety on site
The Health and Safety (Management in Construction) (Jersey) Regulations 2016 (opens in a new tab) cover building work in Jersey. When you’re a householder, the client duties pass to your designer, or to the builder if there isn’t one. Where more than one contractor is involved, one must be appointed as principal contractor, and longer projects, over 30 working days or 500 person-days, need a health and safety project co-ordinator and notice to the Health and Safety Inspectorate.
Asbestos in older homes
A Jersey home built before 2000 could contain asbestos (opens in a new tab), and the Government recommends a professional contractor for removal. Some materials, such as insulating board, pipe lagging and sprayed coatings, can only be removed by a licensed contractor (opens in a new tab). If your builder finds something suspicious, work should stop until it’s been checked.
Party walls and neighbours
England’s Party Wall Act (opens in a new tab) doesn’t apply in Jersey. Jersey has its own customary rules, such as the right to put a ladder on a neighbour’s land to maintain your property, which Citizens Advice Jersey (opens in a new tab) explains. Talk to your neighbours early, and take legal advice before building on or near a boundary.
Quotes and your rights
Jersey Trading Standards explains (opens in a new tab) that a quotation is a fixed, legally binding price, while an estimate is a guess. For building work, get a written quotation that says what’s included, when payments are due and how changes will be priced. The Supply of Goods and Services (Jersey) Law 2009 (opens in a new tab) requires the work to be done with reasonable care and skill.

Questions
Common questions
Do builders need a licence in Jersey?
There’s no trade licence or register of builders. Most businesses need a business licence, but that controls who can run a business and employ staff, not the quality of the work. Check recent local jobs and references instead.
Do I need planning permission and building permission for an extension?
Usually both. Planning permission covers what you build and how it looks, and building bye-law permission covers how it’s built. Some small extensions are allowed without planning permission under the General Development Order.
What is a completion certificate?
When building work with bye-law permission has passed its inspections, the Government of Jersey issues a completion certificate. It’s an important record to keep, so ask your builder for it at the end.
Does the Party Wall Act apply in Jersey?
No. The Party Wall Act covers England and Wales only. Jersey has its own customary rules on boundaries, so take legal advice before building on or near one.
Who is responsible for safety when I hire a builder?
Under Jersey’s 2016 construction regulations, when the client is a householder, the client duties pass to the designer, or to the builder if there’s no designer.
What if my house might contain asbestos?
Homes in Jersey built before 2000 could contain asbestos. The Government recommends a professional removal contractor, and some materials, such as insulating board and pipe lagging, can only be removed by a licensed one.
