UW and your boiler

14 January 2021 - UW offers customers a range of services related to boilers. Need a new boiler? We can certainly help.


Is a gas boiler the only option?

We're aware of other low carbon fuel options coming to the market - some of which come with government grants - such as heat pumps.

Currently heat pumps are significantly more expensive than gas boilers, and often require considerable changes to your home, both in terms of heating system and energy efficiency to function adequately.

As it currently stands, we expect gas boilers to continue to be installed until 2035 and to be maintained beyond this.

For more information about ways to heat your home visit the Energy Saving Trust website.

How can I pay for my boiler?

You can pay by using your bank card or on 5/10 year finance.

If you pay with a card, you'll need to pay a £100 deposit over the phone when you book your installation. The remaining balance will be taken once the installation is complete, using the same card details the deposit was paid with.

If you pay by finance, your monthly payments will be made directly to one of our finance providers (e.g Barclays) and will not appear on your UW monthly bill.

Will the boiler appear on my monthly bill?

If you pay for your boiler upfront (e.g. by cash) you'll receive an invoice from Glow Green, a UW company. You won't see your boiler installation appear on your monthly bill.

If you choose one of our competitive monthly finance options from one of our finance providers (e.g. Barclays), all payments will be processed through them. You won't see the boiler installation appear on your monthly bill.

Do I need to pay a deposit for my boiler?

If you pay by finance, you don't need to pay an upfront deposit for your installation.

If you choose to pay by card, you'll need to pay a £100 deposit over the phone when you book your installation, with the remaining balance to be paid immediately after the installation.
