Heat load surveys and system design in Liverpool

No two rooms in Liverpool gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. North West summers are cooler, so many systems here earn their keep as efficient heaters, with cooling for the warmest weeks.

Every Liverpool quote starts with a room-by-room survey rather than a guess from floor area. As well as Liverpool itself, our Merseyside coverage takes in Birkenhead, St Helens and the towns around them. That includes the L1, L2, L3, L5, L6 and 3 more postcode districts.

Prices in Liverpool

Our North West England guide price for heat load surveys and system design is £375–£1,195 for a standalone design pack, VAT included. It is a touch below the UK middle, as trade rates in North West England tend to be. Larger homes, more zones and full drawing sets for a builder are what move a design pack towards the upper figure. As an example, the Design pack option (drawings and schedules for one home) would typically be £375–£745 here.

Planning and permissions

Since 29 May 2025, England's permitted development rules allow larger outdoor units (up to 1.5 m³) and no longer require a 1 m gap to the boundary, provided the MCS 020(a) noise check is met. Listed buildings and pitched-roof installs still need permission.

The survey

On a survey in Liverpool the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows. Surveys in Liverpool cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.

What is included

Every job in Liverpool includes:

  • Written proposal with options
  • Room-by-room heat gain and heat loss

FAQ

Common questions in Liverpool

Who carries out the work in Liverpool?

F-gas certified engineers working for Aircon Installers. Your contract is with S&K Property Investments and Improvement Ltd, which trades as Aircon Installers, and your quote names who will do the work and the F-gas company certificate that covers it.

Is the survey in Liverpool really free?

Yes, for new installations. The survey and written quote are free and there is no obligation to go ahead.

How long does the installation take in Liverpool?

Survey 1–2 hours. We confirm the timing, and any days with no cooling or heating, in your written quote.

Do you cover all of Liverpool?

Yes, including L1, L2, L3, L5, L6 and 3 more. We also cover nearby Birkenhead and Wallasey.

Will the outdoor unit need planning permission in Liverpool?

Most houses can have an outdoor unit under permitted development if it meets the size, number and MCS 020(a) noise conditions. Flats and listed buildings usually need permission or consent. We check on survey.

Why can't you just quote from floor area?

Two rooms the same size can need very different units because of glazing, orientation and use. Sizing from floor area alone is the main cause of systems that never feel right.
