It is good practice to regularly review suppliers and tariffs for your church and church hall utilities.
You might also like to look at the deals available via the Church of England’s Parish Buying scheme website.
Advice about using green energy suppliers can be found here, and articles about steps churches can take to reduce their energy use can be found here.
Charities, including all PCCs (even those not registered with the Charity Commission because their income is below £100k) need only pay 5% VAT on their utility bills. Please make sure that you are not paying the usual VAT rate of 20% on gas, electricity or oil. If you are then contact your supplier and ask for the reduced rate to be applied. If your income is less than £100k then you will be a charity excepted from registration. If needed you can refer your supplier to the Charity Commission website which explains the status of excepted charities.
You could also provide your Gift Aid number (which usually begins with an X) as proof that HMRC recognises the PCC as a charity for tax purposes.
