Introduction: Since 2013, as part of any house sale, local council land searches have included a land search to establish if the property is in a radon affected area. As sellers you will also be asked if you have measured for radon in your home and if you have taken any action as a result. This fact sheet is to help estate agents, solicitors, landlords, homeowners and tenants, house buyers and sellers to overcome any barriers when the radon land search reveals there is radon in your property area. Local authority search Form and Sellers property information form: When buying or selling a property you will come across two forms that may disclose information about radon. These forms are known as CON 29R and TA6. These forms may be the first time a buyer or seller sees any reference to radon gas and this may be worrying. Radon Protection UK has produced this document to help understand what to do when radon becomes a subject of the buying or selling process, and aims to assist buyers and sellers through the stages required to bring the transaction to a successful conclusion. • If your property is in a radon affected area then mitigation works are likely to be required to be carried out. • Finding a solution, should one be required. (Known as radon mitigation / remediation)
Finding a solution: When radon levels are 200 Bq/m3 or above, then you should consider action to reduce your radon levels. There are two ways you can resolve any issues during the sale or purchased of a property. You can undertake remedial action prior to the sale, or consider a radon Retention (sometimes called a radon bond).
Arranging a radon bond (radon retention): If you do not wish to go through the process of remediation work, or time limits the completion of the property sale / purchase, then a radon retention may be a solution. Under this system, the seller and buyer agree on a sum of money that is likely to be enough to cover the cost of a typical radon remediation system should one be required. The money is taken out of the buyer’s purchase price and held by a third party (for example, a solicitor) until any remediation work is completed and a radon test result is known. Both parties sign a contract that stipulates how the bond will work and a period of time for the radon testing and remediation work can be set. Sometimes the money is released before the work is carried out to fund the remediation. Any testing and remediation work is paid for by the retention money. For the bond system to work, it must be fair to both parties. It must reflect reasonable but adequate costs. Radon Protection UK suggests that in most cases a figure of £1800£2500 be retained. This should be enough to cover most scenarios but advice should be taken on a suitable value for individual properties to give exact costs. The bond’s life must also be realistic, allowing – for example – at least four months from completion of house sale to obtain a radon test result. If this result is at or above the Action Level, another three months should be allowed for the completion of remediation work. If testing reveals levels below the action level, then no further action is necessary and the bond money is released back to the seller.
About Radon Protection UK: We aim to reduce radon levels as low as possible in both existing properties and new homes below 200Bq/m3. Once radon levels have been established, we provide a survey of your property prior to any works and provide a detailed quotation for the mitigation works and the cost will depend on the levels, location and property type. Our team have many years of experience implementing these methods in buildings and successfully bringing radon levels down to an acceptable level. A radon retest measurement should be conducted after completion of works to ensure radon levels have been reduced to an acceptable level, which we can also provide.
