Will I need new radiators or underfloor heating?

Many homes can keep existing radiators but may need larger or low-temperature radiators to run efficiently. Underfloor heating is ideal but not essential; we provide honest advice and costed options for radiator upgrades or a hybrid approach that keeps a boiler for peak demand.

How long does an installation take and how disruptive is it?

Typical domestic installations take 2–5 days on site depending on scope — siting the outdoor unit, any cylinder work and emitter changes determine duration. We protect floors, work tidily and keep disruption to a minimum, and provide a clear schedule before starting.

What maintenance and servicing does a heat pump need?

Heat pumps need annual servicing to check refrigerant circuits, electrical components and controls. Regular maintenance keeps efficiency high and helps preserve warranty conditions; we offer planned servicing and emergency support across Maidstone and Medway.

Do you handle warranties and paperwork for compliance?

Yes. We complete all commissioning checks, provide written handover documentation and register warranties with the manufacturer where available. Our engineers are trained to industry standards (HeatGeek, BPEC) and provide the paperwork required for compliance and future servicing.

Site survey & heat-loss calculation

We visit, inspect insulation, lofts, radiators and cylinder arrangement, then run a full heat-loss calc to size the heat pump and assess whether radiator upgrades or low-flow changes are needed.

Tailored system design & transparent quote

You receive a written proposal detailing unit size, cylinder and control recommendations, any radiator or system changes, installation timetable and transparent pricing — no hidden extras.

Installation, commissioning & handover

Our Gas Safe‑registered and HeatGeek/BPEC-trained engineers fit the unit, commission controls, show you how to run the system and provide all paperwork and manufacturer warranty registration where available.

“I can’t recommend this plumber highly enough. I needed help very quickly after my bath cracked, and he responded promptly and got everything sorted in no time. He completely turned my bathroom around and the standard of work was excellent. He replaced my floor, installed a new 3-piece suite, and fitted a new shower, all to a very high standard. He attended with his apprentice and they were both polite, professional, and extremely helpful throughout the whole job. The work was carried out efficiently with great attention to detail, and they left no mess at all when finished. Thanks Gents-Jordan”

Frequently Asked Questions

Most properties are suitable but suitability depends on insulation, existing emitters and hot-water demand. We carry out a heat-loss calculation and inspect radiators, loft insulation and the hot-water cylinder to confirm whether an air-source unit will deliver the required comfort and efficiency.
