I really thought we needed a new boiler and was getting worried about the cost but Karl was amazing within a couple of hours our boiler was up and running and he really put our minds at ease! The cost was extremely fair and his standard of workmanship was just superb! I cannot recommend Castle Heating enough, we have two young children so to have our boiler up and running the same day was brilliant and saved us alot of trips to the bathroom with a kettle! Not to mention the very cold night it was! Thank you so much Karl your a true gentleman who certainly knows his trade inside and out
