Replacing storage heaters: what to expect

From the first phone call to the old heaters leaving the house. What happens at each stage, and what you have to do.

In this guide

Replacing night storage heaters is the job we do most often. If you’ve been putting it off because you don’t know what it involves, this is the whole process.

The short version: a survey, a written quotation, and usually a single day’s work. No pipework, no boiler, no floors up.

Why most people switch

Storage heaters charge up overnight on cheap electricity and release that heat through the day. The problem is in the word overnight — the heat is bought before you know you need it.

So you get the two complaints we hear constantly. The house is warm at breakfast when everyone’s leaving, and cooling down by the evening when everyone’s home. And if you need a boost at 6pm, you’re drawing power at the expensive daytime rate the tariff charges you for the privilege of a cheap night.

Heating on demand is a different model: each room, when you want it, at one rate.

The survey

Neil visits — he’s our own surveyor, not a subcontracted salesperson — and goes room by room.

It takes no more than an hour. He measures each room, looks at insulation, glazing and ceiling height, and asks how you actually use the space. That last part matters: a dining room used twice a week doesn’t need what a sitting room needs.

He’ll also check your consumer unit and existing circuits.

What you need to do: make sure he can get to the consumer unit, and have a recent electricity bill to hand if you’d like the running-cost estimate to be accurate. Otherwise nothing.

It’s free, there’s no obligation, and nobody will ask you to decide on the day.

Your quotation

You get a formal written quotation, itemised, with every radiator sized for the room it goes in.

It’s a fixed price for your house, not an estimate from a price list. If anything needs doing to your electrics, it’s priced in that document before you agree to anything — so nothing appears later.

Then it’s yours to sit with. No deposit, no deadline.

Installation day

Most homes are done in a day.

Our own engineers do the work. They take the old heaters off the wall, fit the new radiators, wire them in and set the controls up with you before they leave. There’s no pipework to run and no boiler to site, which is why it’s quick.

They’ll also tidy up. Storage heaters are dusty things to remove and we’d rather you didn’t spend the evening hoovering.

What happens to the old heaters

They go with us, as part of the install. You don’t need to arrange a skip or a council collection.

Storage heaters are heavier than they look — the bricks inside are the whole point of them — so this isn’t a job to take on yourself. Older units sometimes contain materials that need specialist handling; we’re qualified for that and we make the arrangements, so you don’t need to.

If you want to keep a few of the bricks, say so and we’ll leave them. People do — they hold heat beautifully under a pizza stone.

After the install

Every radiator carries a 30-year manufacturer’s guarantee. We add five years’ cover on parts and labour for the whole system, electronics included — more than twice what most installers offer.

Our aftercare line is answered after the install, not just up to the sale. If something isn’t right in year three, you’re calling the company that fitted it.
