10 Gas Boiler Servicing / Repair
Posted 3 days ago
Boiler repair
We called Graeme from Excel Gas as our heating wouldn't turn off during the heatwave in June! He came out asap and repaired the faulty part quickly and efficiently. We highly recommend Excel GasVerified reviewerJob location: PO710 Gas Safety Checks - CP12

Excellent Gas Safety Inspection Service
Excellent service from start to finish. I needed Gas Safe certificates carried out for two separate flats that I own, and the whole process was handled professionally, efficiently, and with great attention to detail. Communication was excellent throughout, appointments were arranged promptly, and everything was completed on time with minimal disruption to my tenants. Both gas safety inspections were completed thoroughly, and all certification paperwork was provided quickly afterwards.Verified reviewerJob location: PO510 Gas Boiler Servicing / Repair

Remove, dispose of redundant warm air heater & cap and test gas supply.
Graeme came on time, dismantled and removed old warm air heater very efficiently. Then capped gas outlet and tested cap effectiveness. Finally took away old warm air heater. Will be using Excel gas to remove and cap gas hob too. Can't recommend enough.Verified reviewerJob location: PO7RThe B10 Gas Boiler Servicing / Repair
