Why Aeriva

Designed properly. Installed properly.

A heat pump is only as good as the system it's built into. We treat the design as the product — not a formality before the install.

01

Low flow, always

Radiators and pipework are sized for low flow temperatures from day one — the single biggest driver of running costs.

02

Room-by-room survey

Heat loss is calculated per room, not guessed at the door. The system matches the house, not the other way round.

03

Serviced, not abandoned

We tune performance after handover — most running-cost problems show up in year one and are fixable.

The process

Three steps to a full survey

No pressure, no hard sell — a clear picture of cost and suitability before anyone visits.

01

Answer a few questions

Tell us about your property, current heating and insulation. Takes about two minutes.

02

See your estimate

Likely heat pump size, running cost range, and grant eligibility — sent straight back to you.

03

Book a survey

We confirm the design in person: heat loss, flow temperatures, and a fixed system check.

Boiler Upgrade Scheme

Government grant support

Most oil and LPG heated homes qualify. We handle the MCS-certified paperwork as part of the install.

Questions

Heat pump FAQs

Can I get a heat pump estimate online?

Yes — answer a few questions about your home and we'll send back a likely system size, cost range and grant eligibility before anyone visits.

Will I need new radiators?

Sometimes, on specific rooms rather than the whole house. Our survey calculates this room-by-room instead of assuming a full replacement.

Do heat pumps work in older homes?

Yes, provided the system is designed for the property. This is exactly what the flow-temperature-led survey is for.

How do I claim the BUS grant?

We handle the MCS-certified paperwork as part of your installation once your survey confirms eligibility.
