BTO Key Collection to Electricity Switch: A New Homeowner's Utilities Timeline

Before key collection: activate your SP Group account

HDB's own guidance is to set up your utilities account with SP Group before you move in, ideally at least a day before your key collection appointment — that way you have running water and electricity for your defects check on collection day itself. You can apply online, through the SP Utilities app, or in person at the SP Services counter at HDB Hub, with your identification and proof of ownership (your HDB award letter or equivalent) on hand.

If you didn't set it up beforehand

If you collect your keys without an SP account already active, you can still open one afterward — but don't leave it too long. SP Group's pre-turn-on facility (power and water available for your defects check before your account is fully set up) is generally only held for a few days after key collection before it's withdrawn, so treat this as one of the first things to sort out, not something to defer until after renovation planning.

What happens automatically once your account is open

The moment your SP Group account is active, you're billed at the default regulated tariff — the same rate everyone starts on, and the one our SP tariff guide explains in full. Nobody is auto-enrolled into an OEM retailer plan on your behalf; that only happens if you actively sign up with one. You'll also be charged a security deposit on your first bill — see our hidden fees checklist for how that's sized.

Switching to an OEM retailer: no deadline, but no reason to wait either

There's no compulsory window and no penalty for staying on the regulated tariff as long as you like — switching to an OEM retailer is entirely optional and can happen at any time after your SP account is set up. But there's also no benefit to waiting: every month you stay on the default tariff instead of a cheaper fixed-rate plan is a month you're paying the difference, since nothing about a new account gets you a better starting rate automatically. Once your SP account is confirmed, comparing plans takes a few minutes on our comparison page, and switching itself takes about 5 business days once you sign up with a retailer.

Two things worth checking while you're at it

If you're a Singaporean HDB household, you'll likely be eligible for U-Save rebates against your SP Services utilities account regardless of which retailer you end up choosing — see our U-Save guide for how that's applied. And if you don't yet know your likely monthly usage in a new flat, our usage-by-flat-type breakdown gives you a reasonable starting estimate by room count.
