Business Services

Boiler Service

Boiler servicing should be an item on your annual To-do list. Ideally carried out in the summer months to avoid any long periods without heating or hot water should a fault be identified. It is also typically our quieter time of year so bookings are easier to come by.

Why should I service my boiler?

1. An annual boiler service is usually required to maintain any manufacturers warranty.

2. Seals and other components can degrade over time and become dangerous. Regular checks give peace of mind and keep you and your family safe.

3. You can pick up on issues before they escalate.

4. You could save money on your energy bills, our Gas Safe engineers will check that your boiler is running efficiently.

5. If you're a Landlord, it is a legal requirement.

6. Some house insurance policies require a boiler service to maintain their validity.

Boiler Installation

Boiler installation can vary from a simple like for like combi swap, to a full central heating system with radiators and boiler in a new location.

We have structured prices for the most common installation types, so whether you are converting from an old boiler and hot water tank (conventional boiler) to a combi, or swapping a combi for a combi, our prices are consistent and fair.
