Comfort and heating
Cold rooms, slow heating and uneven warmth
Comfort is about steady temperatures in every room, not just a hot radiator. Most discomfort comes from heat escaping faster than the system can replace it, or a system set up to run too hot and too briefly.
Signs you may notice
- Some rooms never get warm
- Heating takes hours to feel comfortable
- Radiators hot at the top, cold at the bottom
- Frequent boiler faults or pressure loss
- High bills for little comfort
Common causes
- Undersized or poorly balanced radiators
- Air or gas trapped in the heating water
- Heat loss through walls, roof, floors and windows
- High flow temperatures with short on and off cycles
Free checks you can do today
- Bleed and balance radiators, then note which rooms stay cold
- Try lowering boiler flow temperature to 55 to 60°C for a week
- Write down which rooms are used most, and when
Technologies that can help
Air source heat pump
Runs low and steady, sized to a room by room heat-loss calculation, not a guess.
Heat Saviour
Supports heating system efficiency, modelled until measured at your property.
VorteXtract
Removes trapped gas from heating water so heat reaches the rooms. It is a hydronic product, not ventilation.
Confirmed at the survey
- Room by room heat-loss figures
- Emitter sizes and pipework
- Existing system condition and water quality

Insulation and glazing
Draughts, cold glass and heat that escapes
Fabric comes first. Every watt that stays inside is one you never pay for. Windows are often the weakest point, especially single or early double glazing, and in homes where the original look matters.
Signs you may notice
- Cold to touch windows
- Draughts near frames and doors
- Condensation on glass
- Outside noise is intrusive
- Curtains moving when closed
Common causes
- Low performance glazing and worn seals
- Gaps at frames, skirting and loft hatches
- Thin or missing loft and wall insulation
Free checks you can do today
- Hold a hand near frames on a windy day
- Check loft insulation depth (aim for about 270mm)
- Count windows and note which are original or listed
Technologies that can help
PassivGlas vacuum glazing
Judged on installed whole-window Uw, frame and edge included. Can often keep original frames.
Draught proofing and loft top up
Low cost, high value first steps we will always point out, even if you buy nothing from us.
Confirmed at the survey
- Window sizes, frame condition and heritage constraints
- Insulation levels and air leakage points
- Any planning or listed building limits

Ventilation and air quality
Condensation, mould and stale air
A warmer, more airtight home needs controlled fresh air. Without it, moisture from cooking, washing and breathing settles on cold surfaces and becomes mould.
Signs you may notice
- Black mould in corners or behind furniture
- Streaming windows in the morning
- Musty smells
- Stuffy bedrooms
- Laundry slow to dry indoors
Common causes
- Moisture with nowhere to go
- Cold spots where walls or glass meet warm air
- Blocked or missing extract fans and trickle vents
Free checks you can do today
- Note where and when condensation appears
- Check extract fans actually pull a sheet of paper
- Open trickle vents and keep lids on pans
Technologies that can help
Breathe ventilation by Amporah
Continuous, quiet airflow designed around moisture and comfort. No heat recovery credit is claimed without tested data.
Confirmed at the survey
- Moisture readings and mould locations
- Airflow and existing ventilation
- Noise and filter access needs
