Company has emailed us to inform us:
I have spoken to Ideal, and they have confirmed that we have explored all the options available, and their engineers would follow the exact same process.
I can assure you the boiler is safe, and you do not need to worry yourself about this.
Unfortunately, following discussions with the manufacturer we do not think we can solve the squeak, Ideal have advised us that boilers can sometimes develop small noises with age.
As a goodwill gesture we are happy to credit the invoice for the gas valve and refund your payment.
To date we have paid them £65.00 for a iffy boiler service, £225 for a failed repair and £162 for work we did not sanction or agree too?
We are going to accept the refund of £162 and put a line under the matter. What we find very strange for manufacture Ideal boiler to openly admit in writing that there boiler have an un-repairable fault ?
Unfortunately I have suffered a brain injury and occasionally I get confused and often say the wrong thing.
