Frequently Asked Questions

How much does a new central heating system cost?

Because every system we install is bespoke, costs vary based on the size of the property and the technology used. However, we pride ourselves on transparency. After an initial site visit, we provide a detailed, fixed-price estimate so you know exactly what to expect with no hidden surprises.

Will a new central heating system lower my energy bills?

Absolutely! By moving away from “box swapping” and toward an engineered system, our customers often see a significant reduction in their gas or electricity consumption. A system that is balanced and sized correctly doesn’t have to work as hard to keep you warm.

Do I need a full central heating design before installation?

Yes, proper central heating design is the only way to ensure your system actually operates at peak efficiency. Without a professional design, you risk installing a system that is oversized (which wastes energy and wears out parts faster) or undersized (leaving you with cold spots).

For any new installation, major renovation, or transition to a low-carbon system like a heat pump, a full hydraulic and thermal design is essential.

How do you calculate what’s best for my home?

We remove the guesswork by performing a precision room-by-room heat loss assessment. This involves calculating exactly how much energy your property loses through its walls, windows, and insulation.

By combining these thermal calculations with detailed hydraulic design, we can specify a system that delivers maximum comfort and the lowest possible flow temperature. This ensures you system is engineered to be as energy-efficient and cost-effective as possible – whether you’re using a modern boiler or a low-carbon heat pump.
