ASHP or GSHP?

Air source heat pump survey UK or wider heat pump survey?

Use this route when the system is confirmed as air source. If the property is still being considered for ASHP or GSHP, start with the broader heat pump survey.

What we measure Report and examples Access for the visit
Air source route

Air source heat pump survey evidence installers can use before quote, design, and BUS checks

An ASHP survey should do more than prove someone visited the property. It should capture the evidence that affects siting, MCS 020(a) sound inputs, electrical route, heat loss assumptions, existing heating, and whether the installer can move the job forward without another site visit.

Siting

Outdoor unit and sound context

Photos, distances, boundary context, access notes, and obvious siting constraints are recorded so the designer can review the ASHP route properly.

Existing heating

Boiler, cylinder, emitters and controls

Current heating evidence matters for heat loss, design choices, grant paperwork and supplementary-heating checks under the updated BUS guidance.

Next step

BUS v5 survey evidence guide

Use the BUS v5 guide when the job depends on grant eligibility, EPC position, air-to-air eligibility, or retained heating evidence before quoting.

Survey checklist

Air source heat pump survey UK: what gets captured on site

Design and operations need enough site evidence to decide what happens next. Vertex records the ASHP details that affect suitability, quote risk, heat loss, sound checks and installation planning.

Property and heating

Existing system, hot water and emitter context

Boiler, cylinder, controls, emitters, bathrooms, occupancy notes and visible fabric context are recorded so the office is not pricing from guesswork.

Electrical and routes

Fuse board, meter position and practical access

Electrical evidence, meter location, cable-route context, access constraints and service-space notes help design spot problems before the install date is promised.

Design handover

Heat loss, MCS 020(a) and report-ready evidence

Room measurements, site photos, boundary context and assumptions are grouped so heat loss calculations, sound checks and quote review have a clearer evidence trail.

The site detail that matters

We capture the bits that decide whether an ASHP job is straightforward or awkward: location, routes, electrics, and usable space.

What’s included

What happens during an air source heat pump survey

A proper ASHP survey should answer the siting, sound, electrical, and heat-loss questions before the design team has to guess.

Location

Unit siting context

  • Outdoor-unit positions and distances to windows and boundaries
  • Delivery access, mounting and drainage context
  • Pipe and cable routes back into the property
Measurements

Room and heating measurements

  • Room dimensions, floor type, windows and external doors
  • Radiator sizes, heating controls and hot-water equipment
  • Visible construction and insulation; assumptions recorded for heat loss
Evidence

Photos as proof

  • Meter, main fuse and consumer-unit photographs
  • Boiler, cylinder, controls and equipment labels
  • Loft insulation and restrictions where safely accessible

Arrange access to every room being measured, the heating and hot-water equipment, meters, consumer unit, loft hatch and proposed outdoor-unit position. If an EPC is booked, have any evidence of hidden insulation or later improvements ready. Send the property contact our ASHP visit and access guide with the appointment.

FAQs

Frequently asked questions about ASHP surveys

An ASHP survey covers outdoor unit siting, boundary and sound context, access routes, electrics, existing heating, cylinder evidence, heat-loss inputs, floor plans where needed, and clear site photos.

ASHP surveys start from £250. We confirm whether you need survey only, survey plus EPC, or survey plus heat loss, then agree the final price and lead time before booking.

Most visits take 1-2 hours. The report lands in the portal on completion. EPC follows the next morning, and heat loss is delivered the next day where it is in scope.

You need siting, noise, heat loss, electrics, and route detail before an ASHP job is ready to price, design, or book properly.

Yes. ASHP means air source heat pump. This page covers the site checklist, pricing, report detail and booking route for confirmed air source heat pump work.

MCS 020(a) provides the sound-calculation method for the permitted-development noise check in England. The calculated level must be 37.0 dB(A) or lower at the assessment position. Passing this check does not establish compliance with every planning condition. If the proposed position fails, a different position or layout may allow it to pass; otherwise the planning route needs review. Other UK nations have different rules. Read our sound-calculation guide and the MCS standard.

They need DEA capability for EPC work where relevant, plus real heat-pump survey experience. Our survey team works on renewable installs every day.

Yes. Where it is in scope, the ASHP survey includes the inputs and evidence needed for the MCS 020(a) sound-calculation route so the job is easier to review before booking or design moves forward.
