With Oil costs now higher than ever & rising every year it has never made more sense to look at ways to reduce our fuel bills as much as possible. One easy way of doing this is to replace your old boiler with a new high efficiency condensing boiler. We recommend Grant boilers to our customers due to their high efficiency & reliability, both come with extended warranties which can be linked to a service plan which guarantees them for up to 5 years. All boilers are fitted by OFTEC engineers & in line with current building regulations.
