Fixed monthly Direct Debit makes paying easy. If you set up a fixed monthly Direct Debit you'll save £35 a year on your Energy Service Charge, as well as not having the hassle of arranging payment when your bill arrives.

Simply call us on 0345 302 4312 with your Sort Code, Account Number and a date you’ll like us to take your payment each month. We’re here, 8am-8pm Monday-Thursday, 8am-7pm Friday and 9am-5pm on Saturday.

We’ll review your Direct Debit every 6 months to make sure it covers what you’re using. If it needs to change we’ll write to you giving you 10 days’ notice before any new payment is due.

To pay online, register and login to your online Heat account.

Bills are sent out once a month. We’ll always try to use our automatic meter reading system (AMR) to collect your readings so your bills are accurate. But sometimes the coverage can be poor and it may not always be possible to get remote readings. If this happens, we may ask you to give us your reading.

This is a five digit number ending in kWh that can be found on or near your Heat Interface Unit (HIU). If you’re unable to see the reading you may need to press the button next to the screen. If you can’t find your reading please give us a call on 0345 302 4312. We’re here, 8am-8pm Monday-Thursday, 8am-7pm Friday and 9am-5pm on Saturday.

Your Heat bill is made up of three charges:

A ‘heat unit’ is equal to 1 kWh. Your heat unit rate is the cost per kWh of heat you use. The full amount of heat units used will also be reflected on your bill.

We’ll always try to use our automatic meter reading system (AMR) to collect your readings so your bills are accurate. But sometimes the coverage can be poor and it may not always be possible to get remote readings. If this happens, you can provide us your reading by calling us on 0345 302 4312. We’re here, 8am-8pm Monday-Thursday, 8am-7pm Friday and 9am-5pm on Saturday.

A well maintained gas boiler will operate at around 80% efficiency. This means that for every kWh of gas that you pay for, only 80% of this is actually used to heat your home. The rest is wasted during the heating process. 

A Heat Interface Unit (HIU) takes heat directly from a district heating network so you are paying for the actual heat you use. A kWh of heat is used to directly heat your home, so there is no wastage.

So, although heat unit costs are higher than gas unit costs, fewer units will be used to provide the same level of heat output.

Your Energy Service Charge covers the operation, maintenance and replacement costs of your Heat network including the Energy Centre used to supply your heat.

Peace of mind

The great news is; servicing, maintenance, repairs and replacements of your Heat Interface (HIU) are also included within your Energy Service Charge. Faults are rare, but if you find yourself without heat or hot water, you can call our helpline on 0345 302 4312.
