Annual Servicing - The perfect add-on to new equipment

Your new boiler comes with a manufacturer warranty to protect you against unexpected faults. To keep that in place, your boiler must be serviced once a year by a Gas Safe registered engineer. Regular servicing not only maintains your warranty, but also ensures your boiler is working safely and efficiently, helping to prevent costly repairs and giving you peace of mind that your heating and hot water will be there when you need them most.
