Heating Upgrades During an Edinburgh Renovation: The Best Sequence of Work
Heating decisions are cheapest to change before floors, kitchens and decoration are finished. The sequence should lock design first, routes second and commissioning last.
Direct answer
For an Edinburgh renovation, define rooms and fabric, calculate heat loss, confirm hot-water demand, design the heat source and emitters, agree pipe/flue/condensate routes, then complete first fix before floors and decoration. Pressure-test before concealment and commission, balance and hand over after final finishes.
Record proposed windows, insulation and airtightness because they change room heat loss and emitter sizing.
Identify listed status, conservation-area controls, title restrictions and shared property. Ask the relevant authority or factor about the actual proposed external or common-fabric change; do not assume consent from postcode alone.
2. Complete design before first fix
Calculate room heat loss and select radiators or wet underfloor circuits at the intended design temperatures.
Map flow and return, zones, cylinder, controls, boiler or qualified heat-pump option, gas supply where applicable, flue, condensate and discharge routes.
Coordinate joists, acoustic build-ups, kitchen units, bathrooms and door thresholds. Wet underfloor heating needs a build-up and control strategy agreed with the floor supplier.
3. First fix, testing and records
Lift floors once where possible, protect retained fabric and photograph concealed routes before covering.
Pressure-test relevant systems before floors and walls close. Record valve, manifold and isolation locations for future maintenance.
Agree who reinstates boards, stone, plaster, joinery and decoration; 'making good' should never be an undefined allowance.
4. Final fix and commissioning
Fit emitters and controls after damaging work is complete, then clean as appropriate, fill, inhibit, vent and hydraulically balance.
Commission the appliance and hot-water system, set controls, explain operation and provide certificates, warranties and design information relevant to the completed scope.
Gas work must be carried out by qualified Gas Safe registered engineers. Commercial gas and unvented cylinders require their own appropriate competence.
Frequently asked questions
When should heating be designed during a renovation?
After the room layout and planned fabric upgrades are known, but before floors, kitchens and decoration are finalised. That gives the design reliable heat-loss inputs and keeps routes accessible.
Can heating work be phased while we live in the property?
Often. A proposal can define live zones, temporary outages, protected access and room-by-room reinstatement. The practical sequence depends on the existing circuit and whether safe isolation is possible.
What should be agreed about floor lifting and reinstatement?
State which floors are lifted, who protects and relays them, what happens to damaged boards or finishes, and whether joinery and decoration are included. Photograph concealed routes before closure.
