What size of radiator for replacement?

We’re looking to replace 2 radiators in the kitchen and Utility room, the old ones measure 390mm and 590mm wide, do we need exactly the same as replacements (can’t find any this size) or would we need the 400mm and 600mm as replacements?

Advice from 9 local tradespeople

any measurements that fit the place where radiator will be fixed can be applied.

400mm & 600mm would be the closer sizes for the replacement, though the pipework needs to be redone to accommodate for new rads fitting

You can replace them with any size you wish you will need the pipework altered tho.

Generally if you keep the width the same there should be no issues. The new radiator will come with brackets.

400x600

Pipework can be altered to suit

I believe that size Ok it can be replaced

If you do want to change the size of your radiator, this will mean adjustments will have to be made to your pipework . To replace a smaller radiator with a larger one or larger to smaller your floor boards will need to be lifted up to access the pipework below to make the necessary adjustments.
If you want like for like then you need the exact same size for there to be no adjustments.

Hi,
400 & 600 will be fine,
The pipe work may need slight adjustment but should be ok
