Air Tightness Testing For Homes & Residential Properties

If your energy bills feel higher than they should be — or your home just doesn’t feel as warm or comfortable as it should — there’s usually a reason behind it.

And most of the time, it’s not obvious.

Heat loss, poor airflow, and hidden gaps in the building all affect how your home performs. But without proper testing, it’s hard to know what’s actually causing the problem.

We help homeowners understand how their property is really performing — and what needs to change to improve it.

Who This Is For

This service is typically used by:

  • Homeowners dealing with high energy bills
  • Landlords responsible for property standards
  • Buyers wanting to understand a property before purchase
  • Homeowners planning energy efficiency upgrades
  • Property owners dealing with damp or condensation

If something doesn’t feel right in your home – this is how you get clear answers.

Why Homes Don’t Perform As Expected

Most homes lose more heat than they should.

And it’s not always down to insulation.

Common issues we see include:

  • Air leaking through gaps around windows, doors, and floors
  • Poor or inconsistent insulation<
  • Ventilation that’s either too much or not enough
  • Cold spots and uneven temperatures throughout the home
  • Condensation, damp, and mould caused by poor airflow

The problem is, these issues aren’t always visible.

So people end up spending money on upgrades that don’t actually fix the root cause.

What Happens During A Test?

We use specialist equipment to measure how air is moving through your home.

The process involves:

  • Setting up calibrated fan equipment
  • Measuring how quickly air enters and leaves the property
  • Identifying areas where air leakage is likely to be happening

The result gives you a clear picture of how your home is performing – not just how it’s supposed to perform.

Energy Performance Checks For Homes

If you’re not sure where the problems are, this is usually the best place to start.

We carry out detailed energy performance checks to assess how your home is actually working.

This helps you:

  • Identify where heat is being lost
  • Understand what improvements will make a difference
  • Avoid spending money on the wrong upgrades
  • Improve efficiency without overcomplicating things

Air Tightness Testing For Homes

Air tightness testing measures how much uncontrolled air is leaking in and out of your home.

That matters because:

  • Too much air leakage = heat escaping and higher energy bills
  • Too little ventilation = condensation and poor air quality

Our testing helps you:

  • Understand where heat is being lost
  • Identify areas that need improvement
  • Improve comfort and consistency across your home
  • Reduce wasted energy
  • Make informed decisions before spending money on upgrades

We don’t just give you a result — we explain what it means and what to do next.

Energy Performance Checks For Homes

If you’re not sure where the problems are, this is usually the best place to start.

We carry out detailed energy performance checks to assess how your home is actually working.

  • Identify where heat is being lost
  • Understand what improvements will make a difference
  • Avoid spending money on the wrong upgrades

EPC Certificates And Compliance

If you’re selling, renting, or improving a property, you may need an EPC (Energy Performance Certificate).

We can provide EPC assessments to confirm your property meets the required standards.

More importantly, we help you understand:

  • What your rating means
  • What’s affecting it
  • What changes will actually improve it

Ventilation And Indoor Air Quality

Making a home more airtight is only part of the picture.

Without proper ventilation, you can create problems like:

  • Condensation
  • Damp and mould
  • Poor indoor air quality

We assess how airflow is working in your home, so you can improve efficiency without creating new issues.

Residential FAQs

An air tightness test measures how much uncontrolled air is leaking in and out of your property. It helps identify where heat is being lost and how efficiently your home is performing.

It’s not always a requirement for existing homes, but it’s useful if you’re dealing with high energy bills, planning upgrades, or trying to understand why your home doesn’t feel comfortable.

Yes — by identifying where heat is escaping, you can focus on the improvements that will actually make a difference, rather than spending money on upgrades that don’t solve the problem.

Air tightness is about how much air leaks through your home. Ventilation is about how fresh air moves through it. You need the right balance of both to avoid heat loss, damp, and poor air quality.

Yes — testing can be carried out in occupied homes. We keep disruption to a minimum and work around you where possible.

An EPC (Energy Performance Certificate) shows how energy efficient your property is. You’ll usually need one if you’re selling or renting, but it can also help you understand how to improve your home.

We explain the results clearly and talk you through what’s actually worth improving. You’ll know where heat is being lost and what changes will have the biggest impact.

Built Around Real Homes

Every property is different.

Older homes behave differently to new builds. Extensions, upgrades, and repairs all affect how a building performs.

We keep things simple:

  • Clear explanations — no technical jargon
  • Practical advice you can actually use
  • Flexible appointments to suit you

It’s about helping you understand your home — and what will actually make a difference.
