Question 1

How much does a heat pump cost?

Accepted Answer

Most homes are between £9,000 and £25,000 before any grant, depending on size, insulation and radiators. Our price calculator gives you a range in a couple of minutes.

Question 2

How much does air conditioning cost?

Accepted Answer

A single room is usually £2,200 to £2,600. Two or three rooms cost more, and larger or ducted systems start from £4,200.

Question 3

What grants are available?

Accepted Answer

The government's Boiler Upgrade Scheme can take money off a heat pump if you're replacing a fossil fuel system and meet the rules. We check eligibility at your survey and handle the application. Air conditioning doesn't qualify.

Question 4

Will a heat pump save me money?

Accepted Answer

It depends on what you have now and your energy tariff. Compared with oil, LPG or old electric heating, savings are usually good. Compared with modern gas, running costs are often similar. We'll give you an honest view at the survey.

Question 5

Do heat pumps work in cold weather?

Accepted Answer

Yes. A correctly sized heat pump keeps your home warm well below freezing. That's why we design every system around your home's heat loss.

Question 6

Are they noisy?

Accepted Answer

Outdoor units make a low hum, similar to a fridge, and are quieter than most boilers inside. Indoor air conditioning units are very quiet on normal settings. We place outdoor units carefully to keep noise away from you and your neighbours.

Question 7

Will I need new radiators?

Accepted Answer

Sometimes a few. Heat pumps run at lower temperatures, so some rooms may need larger radiators. Your survey tells you exactly which, and they're included in your quote.

Question 8

Can air conditioning heat as well as cool?

Accepted Answer

Yes. Most modern systems heat efficiently too, which makes them useful all year round.

Question 9

What happens at the survey?

Accepted Answer

A ROOST specialist visits, measures your rooms, checks insulation, radiators and where the units can go, and answers your questions. It's free and there's no obligation. You'll get a clear written quote afterwards.

Question 10

How long does installation take?

Accepted Answer

Most heat pump installs take two to five days. Air conditioning is usually one day for a single room, and one to two days for multi-room systems.

Question 11

Will I be without heating?

Accepted Answer

Only briefly. For a heat pump, you're usually without heating and hot water for a day or two near the end of the install. We'll plan this with you.

Question 12

Who is GWE?

Accepted Answer

GWE is the established company behind ROOST. It's Gas Safe registered, MCS certified and has more than 2,000 customer reviews, and it stands behind our work.
