How to avoid cowboy builders (and how LABC can help)
Homeowners and self builders, find out below how to protect yourself against cowboy builders and rogue traders, and how LABC can help you with that.

The first step
The first step is usually to design your project and ideally you will need the help of an experienced professional, such as an architect, surveyor or engineer.
If you follow this route they will normally submit the building regulations application on your behalf.
There are two ways to make an application (a Full Plans or a Building Notice submission).
In general for extensions we would recommend the Full Plans route for your own peace of mind.
The Full Plans route
A Building Control Surveyor will check your plans when submitted to confirm they meet with the current building regulations.
If they don’t, you or your agent will be advised of what work is needed to achieve compliance.
Once you start work on site a surveyor will call to inspect the work as it progresses.
However, it is your/your builder’s responsibility to ensure the local authority is called out for inspection at critical stages of the build and this will generally be explained fully in correspondence confirming approval of your application.
The final inspection of the work is particularly important and should be carried out before your builder leaves site.
(Your completion certificate is the document which helps to confirm that the work inspected met the building regulations and it will be needed should you sell or remortgage your property in the future.)

The 10 Dos and Don'ts of planning your building project
- DO get at least three written, itemised quotes for your building work as prices can vary enormously. Don’t automatically go for the cheapest quote but ensure your quotes are “like for like” i.e. does one quote allow for all fixtures and fittings to a new bathroom but another builds in a nominal sum of £1,000 with you paying the extra. (Your professional adviser may be able to help check these for you.)
- DO use a reputable builder – preferably one who is recommended to you and whose work you can go and look at and whose existing customers you can speak to. (Ask whether they would use him again, was he tidy, punctual and did he meet agreed deadlines?) Ask potential builders about their expertise in your type of building project, how they would want to be paid, will they give you itemised invoices; can they give you a final completion date?
If in doubt, use an audited competent builder like those found through the FMB. Websites such as Checkatrade, MyBuilder, and Rated People all have their own vetting process, but be wary of manipulated ratings. Check out the vetting process, and look into the company separately before going ahead with them.
- DO spend time early on planning and designing your project as changes made at a later stage can be costly in time lost and additional fees.
- DO have your plans properly drawn up by an experienced professional and ensure that they are submitted to building control (together with your application form and fee) well before you begin work on site so they can be checked and an approval issued.
(Building regulations approval is valid for three years and providing you start work before this time you can continue through to completion with no time limit.) Do get full contact details for your builder and verify them. Be suspicious of a builder who will not hand out or does not have business paperwork, or who only has a mobile phone number or deals solely in cash.
- DO agree with your builder before he starts work who will be responsible for contacting building control to arrange site inspections. Then ensure a call is made before work starts on site and at the regular statutory inspection stages. (These include when work starts, drainage, foundations, damp proofing, steelwork and roof construction as well as the final inspection.)
- DO consider using a written contract if your project is large or complex. Your architect may be able to help you with this or there are a number of simple homeowner building contracts available to buy off the internet.
- DO consider an insurance-backed warranty if you are carrying out larger building works. This will provide funds to put work right should the need arise as even the best firm can run into trouble through no fault of their own. Do check whether your work involves work to a party wall and if so whether you need to liaise with your neighbour or serve a Party Wall Notice on them, this needs to happen a month or two before you start work. Don’t deal in cash only. If you must do this at some stage ensure you get a signed receipt for the payment.
- DON'T arrange to pay large sums of money in advance for work. It is better to make staged payments, such as up to damp course, roof level and completion.
- DON'T assume that if your builder tells you no local authority consent is needed that this is always the case. Check with Planning and Building Control yourself if you are unsure. (Also consider water and sewerage authorities’ consents.) Don’t make alterations to your approved plans unless you check with the Planning and Building Control departments first. If you do, give details of the alterations and agree the timescale and additional costs with your builder in advance.
- DON'T make your final payment to your builder until you are fully satisfied with his work and your completion certificate has been issued.
Don't let this put you off!
