Save your money and avoid using PlumbingForce. I had an electrical issue with my boiler (the circuit board died), which I communicated clearly to them over email and by phone, along with the specific make of my boiler, a Vaillant Ecotec Plus 937 combi. They sent someone over who spent a maximum of 5 minutes looking at my boiler. He then went to his van to call Vaillant, claiming he didn't get a signal in my house, which no one else has ever had issues with. After 10-15 mins, he came back in and told me that the electricals aren't working and need replacing (which is quite literally exactly what I communicated to them in the first place) and then quoted me £900+ for new parts that I found online for less than £200. They prey on people who have urgent needs and use extremely vague and open ended terms & conditions to allow them to engage in borderline fraudulent business practices. It literally says on their website, “Do not rely on information on this site. We make no representations, warranties or guarantees, whether express or implied, that the content on our site is accurate, complete or up to date.” See for yourself - https://www.plumbingforce.co.uk/terms-conditions/ They can do better by simply being less evasive on the phone and through other communications about what services they're able to provide upfront. In hindsight, it's very clear that they were intentionally withholding information to try and close the sale. Once you give them your payment information, that's all they care about. Also, they refuse to provide a phone number for customer service and insist only on emails. Avoid at all costs.
