Every recommendation below explains why it comes first, the evidence behind it, how confident we are, and when it would not apply.

Editorial confidence

You may not need to read the rest of this page

You probably already have enough to act if:

  • You know which rooms underperform and by how much.
  • You have a TRV and thermostat regime that matches how you actually live.

Comfortable living-room temperature range

19–21°C in winter, 22–25°C in summer

Source: Chartered Institution of Building Services Engineers · CIBSE Guide A; outside this, comfort complaints rise sharply.

Acceptable room-to-room variation

≤ 3°C between bedrooms and living spaces

Source: Chartered Institution of Building Services Engineers · Above 3°C, the home reads as poorly balanced regardless of average temperature.

Cold-bridge surface temperature factor (fRsi)

≥ 0.75 at any junction

Source: Building Regulations; Approved Document L · Below this, condensation forms at junctions even at normal indoor humidity.

Who this advice is for

Applies to

  • Homes with rooms more than 3°C colder than the thermostat reading in winter.
  • Pre-2000 properties where insulation upgrades have been partial or piecemeal.
  • Households planning a refurbishment in the next two years; sequencing matters.
  • Anyone with a thermostat that fights the house rather than working with it.

Not intended for

  • New-build homes within their two-year defects period; pursue the developer first.
  • Holiday lets or second homes where thermal mass and slow recovery are acceptable.
01

Get a real fabric picture before changing the heating system.

Why this comes first

An EPC is a planning tool, not a survey. A 90-minute thermal imaging walk in February reveals cold bridges, missing loft insulation and uninsulated bays in a way no model does. The findings reshape every later decision.

Evidence

See the heat loss; then decide.

Loughborough DEFACTO · LETI

Confidence

High confidence. Multiple independent sources agree on the direction and the order.

Exceptions
  • Recent (post-2015) builds with EPC A/B; usually not worth the survey fee.
Next step

02

Set per-room TRVs and a properly scheduled thermostat before adding zones or smart kit.

Why this comes first

Most UK homes still run on a single thermostat and unbalanced radiators. Calibrating TRVs and setting an evening setback typically saves 8–12% of heating energy with no hardware spend; smart controls add a further 5% on top of that, not instead of it.

Evidence

Controls solve 80% of the comfort complaint at 5% of the cost.

EST · DESNZ

Confidence

High confidence.

Exceptions
  • Underfloor-only systems; balancing logic differs and a heating engineer should commission.
Next step
Read: smart controls done right
03

Sequence the deeper fabric measures around the next planned redecoration or extension.

Why this comes first

Internal wall insulation costs the same in plaster and dust whether you do it during a re-decoration or in isolation; doing it standalone doubles the disruption for the same outcome. Tying fabric work to existing plans halves the perceived cost.

Evidence

The right time to insulate is when the room is already coming apart.

AECB · PAS 2035

Confidence

Reasonable confidence.

Exceptions
  • Severe damp or mould; act now, sequence later.

How we'd approach this

Comfort is a fabric problem most people try to solve with kit.

Cold rooms, draughts and uneven temperatures are almost always the building telling you what it needs; we would read the building first. A thermal camera scan in February or a thirty-minute draught audit with a stick of incense will direct the next £5,000 better than any product comparison.

Within the fabric, the order matters: loft first, draughts second, walls third, windows last. Each step shrinks the brief for the next and reduces the chance of a six-figure window replacement that delivers a one-degree comfort gain.

We would only specify mechanical comfort kit (heat pumps, AC, MVHR) once the envelope is on the way to EPC C; otherwise the kit is compensating for the house, runs at lower efficiency for its whole life and never feels quite right.
