<h3>When is a permit required?</h3>
<p>Certain types of electrical work in your flat will require you to obtain a permit from HDB before they can be carried out. All guidelines set by us must be followed regardless of whether a permit is required to carry out a specific electrical work.</p>
<h3>Unauthorised electrical work</h3>
<p>You need to remove all unauthorised work, make good the work carried out, or reinstate your flat to its original condition. This includes:</p>
<ul>
    <li>Not obtaining a permit for works that require one</li>
    <li>Not carrying out works according to guidelines</li>
</ul>
<p>Please seek HDB&rsquo;s approval before starting electrical works that involve:</p>
<ul>
    <li>Electrical items that are not listed in the guidelines</li>
    <li>Technical details that are different from the guidelines</li>
</ul>
<h4>Adherence to terms and conditions</h4>
<p>You must strictly observe the terms and conditions listed here along with other conditions or guidelines put in place by us for such works. Failing to follow these terms and conditions will be treated as unauthorised work.</p>
<h3>Approval for installation of electrical appliances</h3>
<p>Approval is given on the basis of electrical rating only. The approval is not an endorsement of the safety, reliability, or suitability of the appliance for the expressed/ implied purposes by the manufacturer.</p>
<h4>Responsibilities of the flat owner</h4>
<p>You need to ensure that electrical rating of appliances corresponds to the electrical rating stated in its catalogue/ brochure that you submitted to HDB for approval. The approval can be revoked if a difference is discovered.</p>
<h3>Timeline for renovation works</h3>
<ul>
    <li>For newly completed blocks, approved electrical work must be completed within 3 months from the date of the permit</li>
    <li>For existing blocks, the approved work must be completed within 1 month from the date of the permit</li>
    <li>No work is to be carried out before 8am or after 6pm</li>
    <li>Noisy work, such as cutting of tiles, demolition of walls, removing wall/ floor finishes, etc. should only be carried out on weekdays between 9am to 5pm</li>
    <li>Noisy works cannot be carried out on Saturdays, Sundays or Public Holidays</li>
    <li>Only 2 of the <a href="/-/media/managing-my-home/renovation-and-maintenance/renovation/renovation-guidelines/electrical-works/approved-power-tools.pdf" target="_blank">handheld power tools approved by HDB</a>&nbsp;(PDF, 76KB) or their approved equivalent are allowed to be used at a given time</li>
</ul>
<h3>Supervision</h3>
<ul>
    <li>You must supervise all electrical work and ensure that the electrical installation/ air conditioning unit are installed by an Energy Market Authority (EMA) licensed contractor or an <span>air conditioning unit installer </span><span>trained by the </span>Building and Construction Authority (BCA) respectively</li>
    <li>Ensure that all works are carried out in compliance with HDB&rsquo;s guidelines</li>
    <li>Avoid carrying out any Do-It-Yourself (DIY) works involving drilling or hammering from 10:30pm to 7am, as such works generate noise which may inconvenience your neighbours. You should inform your neighbours beforehand if you are unable to keep within these timings</li>
    <li>Renovation debris should not be thrown down your refuse chute or washed down the WC squat pan or floor trap</li>
    <li>You will be required to submit the <a href="https://services2.hdb.gov.sg/webapp/BN31AWERRCMobile/BN31SElectrical?loadAction=electrical">SP Services Ltd (SPSL) Form CS/5H</a> endorsed by HDB to SPSL for testing of any new electrical wiring or extension work</li>
    <li>You must apply to SPSL for inspection of the completed work through your licensed electrical worker</li>
</ul>
<h3>Approval and supervision by other authorities</h3>
<ul>
    <li>You must comply with the law, by-law, rules, and regulations in place for electrical works at all times</li>
    <li>HDB and the Town Council reserve the right to control and give directions in the course of your renovations if required</li>
</ul>
<h3>Indemnity</h3>
<p>Please indemnify and keep HDB indemnified at all times against all claims and proceedings for:</p>
<ul>
    <li>Any damage to or destruction of property</li>
    <li>Injury or death of any person</li>
    <li>Costs and expenses howsoever arising from, in connection with or resulting from the execution of the work</li>
    <li>Losses, costs, charges, expenses and damages, which may be incurred or payable to HDB arising from or in connection with the execution of works</li>
</ul>
<h3>Variations of terms and conditions</h3>
<p>HDB reserves the right to vary these terms and conditions as and when required. Any approval granted will be subject to the prevailing terms and conditions as varied by HDB from time to time.</p>
<p>You should observe and comply with other rules and regulations as HDB and the Town Council may make from time to time in relation to the execution of electrical renovation work in HDB flats.</p>
<h3>Technical terms and conditions</h3>
<ul>
    <li>All wiring installation work must be carried out by an EMA licensed electrical worker</li>
    <li>Embedding or wiring housed in metal/ high impact PVC conduit in reinforced concrete (RC) slabs, beam, column, wall and in wall plaster or other finishes is not allowed</li>
    <li>Diameter and penetration depth of power-driven nails and screws must not exceed 6mm and 40mm respectively</li>
    <li>For flats with concealed electrical wiring (originally provided by HDB):
    <ul>
        <li>Refer to guidelines in Drawing 1  &lsquo;Drilling of Holes in Flats with Concealed Electrical Wiring&rsquo;</li>
        <li>Precautionary measures should be taken to ensure anchors (including hammering of nails) into the slab are located away from the concealed conduits as shown in the concealed conduit layout plans</li>
    </ul>
    </li>
    <li>Electrical wirings in a flat have a limited life span, estimated at an average or 25 years for PVC electrical cables</li>
    <li>You are advised to replace the electrical wiring in your flat when the life-span is over or when conditions have deteriorated</li>
    <li>A licensed electrical worker (LEW) can advise you on the condition of your flat&rsquo;s wiring and whether they require replacement</li>
    <li>Upon completion of any electrical renovation work, you are to apply to SPSL for testing through your LEW</li>
</ul>
