What does a heat pump cost in Scotland?
Current Scottish cost examples for air-to-air, air-to-water and ground-source heat pumps, plus what can change the final price and funding.
HomeownersHeat pumps02Can a heat pump work in an old stone house?
Yes—but the house needs a design that respects its fabric and can heat every room. Here is what to check before deciding.
Owners of older homesHeat pumps03Air source vs ground source heat pumps
Compare land, drilling, seasonal performance, capital work and maintenance before choosing a source.
Homes and estatesHeat pumps04Heat pump radiator sizing without the guesswork
Understand why lower flow temperature changes emitter output and how a room-by-room schedule prevents over- or under-sizing.
Homeowners and designersHeat pumps05Flow temperature: the number that shapes heat-pump performance
Why flow temperature affects efficiency, emitter size and comfort—and why it must be a design output.
Technical buyersHeat pumps06Heat-pump noise, neighbours and placement
A practical placement guide covering sound data, reflections, access and planning context.
Urban homeownersHeat pumps07How to estimate heat-pump running costs honestly
Move from sales claims to a transparent estimate using heat demand, seasonal efficiency, tariff and standing charges.

Homes and businessesSolar & battery12How to size a solar battery around real demand
Avoid paying for unused capacity by matching generation surplus, evening load and tariff strategy.
Homes and SMEsSolar & battery13East-west solar roofs: when a wider generation window wins
Why roof orientation can shape self-consumption and inverter choice—not simply total annual output.
Property ownersCommercial14Building a commercial solar business case
Turn roof area and bills into a decision model that separates self-consumption, export and avoided cost.
Finance and operations teamsSolar & battery15Solar export tariffs: what to compare before you sign
Rate, eligibility, meter requirements and contract terms can change the value of surplus electricity.
HomeownersSolar & battery16What a proper solar roof survey should cover
Structure, condition, shade, access, fire routes and electrical routing belong in the decision—not after it.
Building ownersSolar & battery17Solar PV maintenance: a proportionate plan
Monitoring, inspection and targeted cleaning help protect output without unnecessary service visits.
Homes and facilities teamsPlanning18Solar plus heat pump: design the overlap, not the slogan
The two technologies can complement each other, but winter demand and solar output must be modelled honestly.
HomeownersSolar & battery19Battery storage without solar: when can it make sense?
Time-of-use charging, peak avoidance and resilience can create a case without rooftop generation.
Tariff-conscious homesSolar & battery20Solar grid connection: G98, G99 and why timing matters
A plain-English introduction to network notifications, applications and export limits.
Commercial clientsAir conditioning21Air conditioning cost: what changes the quote?
Capacity, number of rooms, access, pipe routes, condensate and electrical scope explain most quote variation.
Homes and SMEsAir conditioning22Using air conditioning for heating in Scotland
Reversible air-to-air heat pumps can provide fast zoned heat where hot water is handled separately.
Homes and small workplacesAir conditioning23Office air conditioning: design around people, glazing and equipment
Floor area alone misses the heat from occupancy, screens, solar gain and meeting-room peaks.
Office managersAir conditioning24Server-room cooling: resilience before comfort
Continuous load, redundancy, alarms and condensate risk make technical cooling a different brief.
IT and facilities teamsAir conditioning25Commercial air-conditioning maintenance and F-gas responsibilities
Keep records, leakage checks and planned maintenance proportionate to the system and refrigerant charge.
Building operatorsAir conditioning26Single split vs multi-split air conditioning
Compare outdoor space, simultaneous demand, pipe routing, resilience and individual room control.
Homes and small businessesAir conditioning27Where should an indoor air-conditioning unit go?
Good placement balances airflow, noise, servicing, condensate and the appearance of the room.
HomeownersCARES funding28CARES Community Buildings Fund: a plain-English eligibility guide
Check whether your group, its building and the renewable work you have in mind could fit the current CARES rules.
Community organisationsCARES funding29Your CARES evidence pack: what to gather first
