Why customers in Guildford choose OCSCompany

A boiler service is only worth doing if it is done properly. We strip and clean the heat exchanger, run a gas-pressure test, do a flue-gas analysis and leave a fully completed CP12 or service record. None of the ten-minute tick-and-flick visits some firms offer in Guildford.

How a typical job runs

Send us a couple of photos on WhatsApp, drop us an email, or talk it through on the phone. A fixed-price written quote comes back inside 24 hours. There is no obligation and no aggressive follow-up. If you are happy to go ahead, we book a slot that works for you (Saturday mornings included) and confirm the day before. On the day you get a 30-minute "we are heading over" message. The tradesperson arrives in branded clothing with photo ID, finishes the job, and you only pay once you are happy with the finish.
