Heat Loss Surveys

Room-by-room heat loss surveys that turn an estimate into a real design.

A proper heat loss survey helps confirm heat pump size, radiator requirements, hot water strategy and final pricing before installation moves forward.

What the survey covers

Everything you need before final sign-off.

This is where we move from broad assumptions to room-by-room evidence.

  • Detailed heat loss survey for the whole property.
  • Room-by-room heat loss calculations and emitter checks.
  • Radiator sizing and upgrade recommendations where needed.
  • Final system design completed after the survey.
  • Final price only confirmed after the survey.
  • Free home survey before the final design and installation plan is confirmed.

Why it matters

A good survey protects comfort, efficiency and budget. It also avoids oversizing the heat pump or missing radiator work that should have been obvious from the start.

  • Useful for homeowners comparing gas, oil or LPG replacement routes
  • Confirms whether new radiators are actually needed
  • Supports a clearer final quote and installation scope

Not sure if you need a survey yet?

Start with the estimate first. It gives you likely system size, grant deduction and price direction, then the survey confirms whether the numbers make sense for your actual rooms.

  • Useful if you are still comparing heat pump costs
  • Helps decide whether a full survey is worth booking
  • Uses EPC data where available, with local-average fallback when no EPC is found

The survey is the commitment step.

The estimate gives the starting point. The survey gives the evidence: room-by-room heat loss, emitter checks, hot water strategy and the final installation scope.

Why the survey matters

The survey is what stops a heat pump looking fine on paper and failing in real life.

Homeowners usually regret the jobs where the design stage was rushed. The survey protects comfort, emitter planning, hot water performance and final pricing.

It checks the real heat loss

That means the system size is built around the actual home, not a rough assumption from the old boiler or a generic rule of thumb.

It exposes radiator problems early

Emitter issues are one of the most common reasons homeowners end up cold or disappointed after installation.

It makes the final quote safer

It is far better to know the real scope before the installation than to discover the compromises once the job has started.

FAQ

Common survey questions before a quote moves forward.

Many homes across the North West can suit a heat pump well, but the right answer depends on heat loss, radiator performance, hot water demand and controls. That is why the estimate comes first and the survey confirms the final design.
