Wi-Fi heatmap
Find the weak spots in your home
A heatmap shows which rooms get good Wi-Fi and which don't. You just walk around, tap where you're standing, and we do the measuring. It takes about five minutes, and it's the single most useful thing you can show your broadband provider.
1. Set up your map
Take a photo of a floor plan, or simply sketch your rooms on paper and photograph it. No plan? Skip it — you'll get a plain grid to place your rooms on.
Have your home's plan online?
If your home was listed on Rightmove, Zoopla, OnTheMarket, PrimeLocation, OpenRent or Purplebricks, paste the link to that property page and we'll try to pick up the floor plan for you. You can also paste the address of the floor plan picture itself.
Nothing came back? Here's what to do
Zoopla blocks other websites from opening its pages, and a few listings simply don't include a plan. Two easy ways round it:
- 1. Open the floor plan on the listing, screenshot it, then press "📷 Add a floor plan or sketch" above.
- 2. Or press and hold the plan picture (right-click on a computer), choose "Copy image address", and paste that here instead of the listing link.
Only use plans of your own home. Your plan stays private to you unless you choose to share your heatmap link.
2. Walk around and tap where you are
Stand still in a room, tap that spot on the map, name it, then press measure. It takes about 10 seconds per spot. Five or six spots gives a lovely picture.
Tap the spot where you're standing to start
Tips for a map that actually helps
- • Always measure next to the router first — that's your best-case number to compare everything against.
- • Include the room that annoys you most, even if it's the loft or the garden.
- • Keep the phone or tablet still while it measures, and don't stream anything at the same time.
