EH26 · Midlothian · for landlords
Low-temperature heating planned for Penicuik
Air Source Heat Pumps in Penicuik is judged by the building, not the postcode. Strong landlord market across the older Penicuik terraces — block-booked CP12 rounds with same-day digital certificates are a regular EH26 calendar slot.
Cold-climate combi installs, gravity-system upgrades and annual G3 cylinder servicing across EH26. Penicuik's Pentlands exposure and mixed Victorian/new-build stock make spec choices matter every time.
MCS Certified and RECC member, we design and install air source heat pumps across Penicuik. Most of our customers access the Home Energy Scotland Grant (currently up to £7,500) plus an interest-free loan on top — we handle the entire application as part of the quote. Crucially, every system is sized from a proper room-by-room heat-loss survey, not a back-of-the-envelope kW figure, so it actually performs through a Borders winter rather than just ticking a grant box. Access is usually via the A7 and A703.
Penicuik questions worth answering first
How do you stop the boiler locking out in a Penicuik winter?+
EH26 sits high enough that frozen condensate is the single biggest cause of February no-heat calls. We route the condensate internally wherever possible, upsize any external section to 32mm and lag with weatherproof Armaflex — the same Pentlands-grade detailing we use on West Linton and Carlops jobs.
Do you carry out annual unvented-cylinder inspections on the new estates?+
Yes — our engineers are G3-qualified and we cover the Megaflo, Telford and Joule cylinders fitted across the modern Penicuik developments. We test the temperature and pressure relief valves, re-charge the expansion vessel and issue a written service record alongside the annual boiler service.
Does the property itself change the air source heat pumps specification here?+
New-build estates around Mauricewood and Bilston run unvented cylinders — annual G3 inspection plus expansion-vessel re-charge sits alongside the boiler service every year. We confirm that point on site, then match the air source heat pumps specification to the actual building and access rather than assuming every EH26 address is alike.
Who is this Penicuik page written for?+
Yes. The recommendations prioritise landlords who need to check property suitability, emitter changes and grant-ready system design. If the building or occupancy differs, the survey is where we adjust the plan.
Am I eligible for the £7,500 grant?+
Most owner-occupied Scottish homes qualify. We confirm eligibility and guide you through the Home Energy Scotland application as part of the quoting process at no extra cost.
Do I need new radiators?+
Sometimes one or two need upsizing — rarely the whole house. We tell you exactly which (and the cost) inside the written quote, before you commit.

STEP 2
Install & commission
Typically 3–5 days on site, fully commissioned, MCS certified and registered.
STEP 3
Property survey
Full heat-loss survey, fabric assessment and a look at existing emitters and cylinder space.
STEP 4
MCS-compliant design & quote
Sized for your specific property and lifestyle, not a generic spec.

Property and access context
Penicuik details that affect the specification
- Strong landlord market across the older Penicuik terraces — block-booked CP12 rounds with same-day digital certificates are a regular EH26 calendar slot.
- Pentlands-edge exposure makes EH26 one of the colder Midlothian postcodes — we upsize the condensate run to 32mm, route it internally where possible and lag any external section with weatherproof Armaflex.
- Many of the older High Street and Bridge Street terraces still run gravity-fed open-vented systems we routinely upgrade to fully pumped, sealed and TRV-balanced setups with magnetic filters.
- New-build estates around Mauricewood and Bilston run unvented cylinders — annual G3 inspection plus expansion-vessel re-charge sits alongside the boiler service every year.

Share photos and a short description from Penicuik first. We will use the local access and system context on this page to prepare the right visit.
Penicuik is not being treated as an interchangeable location page. The recommendation starts with strong landlord market across the older penicuik terraces — block-booked cp12 rounds with same-day digital certificates are a regular eh26 calendar slot. It then combines air source heat pumps, the needs of landlords, access via the A7 and A703, and nearby coverage toward Auchendinny and Bilston.
