Having moved into our current house 6 months ago, we were keen to update a very old and inefficient heating system prior to winter. The response from many installers was very unimpressive with a number even failing to respond. Eventually we managed to get 3 quotes which were broadly similar (within 10% of each other) which included Rainbox Fix (plus the obligatory sky-high quote from a most unimpressive frontman from that well known national ). We selected Rainbow Fix based on reviews (from another site, admittedly, as the Which? site was a bit sparse for plumbers in our area), his obvious technical knowledge and that general 'feel' we got on his intial visit to quote. We were debating between a Worcester Bosch and Vaillant Boiler/Cylinder combo, but eventually went for the (only very slightly) more expensive Vaillant based on the 7 year warranty on offer. There was no hard sell either way. The system is now up and running, and Roman has proved to be every bit the punctual, hardworking and trustworthy individual we were seeking and hoping for. The eventual cost came in bang on quote except for one extra piece of work which we wanted (moving a water softener) which we discussed seperately and agreed a price on. Overall, the install went smoothly and we have our new system and a new gas engineer in our phone book to call upon if required! We would certainly recommend Rainbox Fix to others and would be happy to be contacted for a reference if required.
