Gas engineer arrived this morning at 8.30 am and left at 11.00 am, the boiler now has had a full service (which originally what we had asked for in the first place) boiler seems ok at the moment.
In affect all we need was a good service to date they have changed the jet, the Venturia tube and finally the gas valve, none that need changing, to day we have paid a total of £452.00 hopefully this will work.
Unfortunately I have suffered a brain injury and occasionally I get confused and often say the wrong thing.
