Skip to main content Skip to footer Solar PV across Westhill, Elrick and AB32, from £7,000 fully installed with 0% VAT. Free survey and a fixed written price. Everywhere else we work, every roof is its own argument. Westhill is different, because Westhill was planned. Conceived in 1963, first houses in the autumn of 1968, then built out in bursts ever since. Council records show years of a hundred and more new homes followed by years of almost none. Which means your street very likely went up in one go, to one specification, with one roof pitch and one covering.
Everywhere else we work, every roof is its own argument. Pitch, covering, orientation, shading and plot geometry all differ from one house to the next, so a measured result on one property tells you very little about the one beside it. Westhill is the exception, and it is the only market we work in where that is true.
The reason is that Westhill was planned rather than accumulated, and it has been built out in distinct bursts rather than house by house. A street here very likely went up in one go, to one developer's specification, sharing a roof pitch, a covering, an orientation and a plot layout with everything around it. So the thing that would be sloppy anywhere else, quoting from what the neighbours are already getting, is here the most accurate information available.
What that changes in practice is the conversation. Tell us your street and we already have a strong idea of the likely build era, the roof geometry and the generation of consumer unit sitting behind the door, before anybody has set off. We still measure your actual aspect, pitch and shading on site before a single panel is specified. We simply arrive knowing what we expect to find, and that is the difference between a survey and a guess.
Because the whole argument on this page rests on numbers rather than adjectives, every one of them is published with its source underneath it: the census table behind the housing mix, the council's own completion record, the full modelling parameters behind the yield figures, and the price we would actually charge you.

Westhill did not grow slowly over two centuries the way a granite town does. It arrived in blocks, and the record of it is in the council's own numbers.
In the early 1960s this was the village of Skene, with fewer than a hundred residents. Then in 1963 an Aberdeen solicitor put forward a plan for a new town here, and the first houses went up in the autumn of 1968. The Aberdeen Solicitors Property Centre still describes Westhill as having been built originally as a garden suburb, and the oil economy did the rest, taking the town to 11,750 people by the 2022 census. It sits roughly six and a half miles west of Aberdeen.
What matters for solar is not the history but the rhythm. Aberdeenshire Council's own housing completion records for Westhill read like a heartbeat rather than a steady line: a year of eighty seven homes, then a hundred and thirty two, then fifty nine, a hundred and ten, sixty two, a hundred and thirty four, and then twenty eight, four, one, one, nothing, nothing.
Read that sequence again, because it is the entire argument of this page in twelve numbers. Housing did not trickle into Westhill. It landed in large blocks, and between those blocks almost nothing was added at all. Every one of those big years is a set of streets that went up together, to one specification, and then stopped.
Aberdeenshire Council, Area Profile Data Tables 2023, Garioch housing completions by settlement. One bar per year of the published Westhill row, in the order it is published. We deliberately attach no years to these figures and publish the shape only.
“Development in Westhill is limited until transport modelling and assessments are undertaken over the next few years to identify the nature of a solution that may be required to allow further significant development to take place in the town.”Aberdeenshire Local Development Plan 2023, paragraph 5.16
Bursts, then stop. And it is going to stay that way for a while, because the council has formally paused further growth pending transport work. So Westhill's housing is a set of closed cohorts. Whole streets went up together, to one developer's specification, and nothing new has come along since to dilute them or blur the boundary between one era and the next. That is unusual, and it changes what an honest solar quote can tell you before anybody climbs a ladder.
Three census areas cover Westhill and Elrick. They are neighbouring parts of one small town, and they look nothing like each other, because they were built at different times.
| Census area | Households | Detached | Semi detached | Flats |
|---|---|---|---|---|
| Westhill North and South | 1,909 | 64.9% | 24.7% | 4.3% |
| Westhill Central | 1,783 | 33.8% | 43.4% | 15.0% |
| Garlogie and Elrick | 1,465 | 55.0% | 26.1% | 10.5% |
| All three combined | 5,157 | 51.3% | 31.5% | 9.8% |
Scotland's Census 2022, Table UV402, Accommodation type, at 2011 intermediate zone level. These are the three zones covering Westhill and Elrick, not a settlement boundary. Percentages calculated from the published household counts.
Westhill North and South is 65% detached with 4% flats. Westhill Central is 34% detached with 15% flats and nearly half semi detached. Those are two halves of the same town, a few minutes' walk apart, and they are built to completely different densities.
That is not an accident of geography, and it is not a coincidence either. It is two different building eras, captured in a census table decades after the fact. And because the town has been built in bursts and then paused, those eras stay clean rather than blurring into one another the way they would in a place that grew steadily.
It is the clearest published evidence we have found that the cohort effect on this page is real rather than a sales line. The census did not set out to record build eras. It recorded them anyway.
Combined, the three zones are 90.0% whole house or bungalow and only 9.8% flats. Just over half of everything is detached.
That is an unusually house heavy stock, and it matters a great deal more than it sounds. It means most Westhill roofs are yours alone: no common property, no co owners, no title deed question, no factor to write to and wait on. The roof you are thinking about fitting panels to is simply your roof.
Compare that with Aberdeen, eleven miles east, where more households live in a flat than in a house and the first question any honest installer has to ask is who owns the roof at all. Here, it is almost always simply you, and the conversation can start with the panels instead.
Four things follow from a street that was built in one go, and they are all things a solar quote normally cannot give you.
Same pitch, same covering, same orientation, same plot geometry, same era of shading from the same generation of planting. A monitored result on one roof is genuinely informative about the one next door. Everywhere else in the north east, quoting from a neighbour's system would be sloppy. Here it is the most accurate thing available, and it is available before we have arranged a visit.
If the house opposite has a dormer that clips the morning sun on the rear plane, yours probably does as well, because it is the same house. Estate planting from the same decade has grown to roughly the same height along a whole street, so the trees that matter are the same trees at the same size. We survey your roof properly regardless, but we arrive knowing what we are likely to find.
A street built in one year got one generation of board. On the earliest Westhill stock that is often the limiting factor rather than the roof, because a board at the end of its life may not take a new solar circuit without being replaced first. We check it at survey and quote it openly rather than discovering it on install day and asking you for more money with the scaffold already up. Consumer units in Westhill covers that side of it.
A cohort is a strong prior, not a survey. Extensions, dormers, re roofs, conservatories, corner plots and rear elevations facing a different way all break the pattern, and plenty of Westhill houses have been altered in fifty years. We use the cohort to arrive informed. We still measure your actual aspect, pitch and shading on site before anything is designed, and if your house turns out to be the exception on its street, the survey is what tells us so.
Two findings from modelling a 4kWp array at Westhill's own coordinates. One of them should stop you worrying, and one of them should stop anybody selling you year round independence.
First, the pitch. The theoretical optimum here is 43 degrees. A standard estate roof sits around 35. The difference between those two is 22 kilowatt hours a year, about 0.6%. Chasing pitch in Westhill is worth almost nothing at all. Orientation and shading are the levers that genuinely matter, and the pitch debate you will be dragged into by other quotes is noise dressed up as expertise.
Second, the seasons. The same array is modelled at 487 kWh in May and 80 kWh in December. That is roughly six to one. Around three quarters of your year arrives between March and September, which means the case for solar here is a summer case and should be presented as one. A battery shifts summer surplus by hours; it cannot shift June into December, and anyone implying otherwise is selling rather than advising.
And what we actually quote. The model says 3,486 kWh a year for a south facing 4kWp array. We design and quote to 2,600 kWh. That is deliberately lower, because the model assumes a clean unshaded plane with a flat loss allowance and a typical year, and a real Westhill roof has a chimney, some soiling, an inverter that is not new, and occasionally a January that is not average. We would rather your system beat our number than miss it. Both figures are here so you can compare us against either, and so you can see exactly how far apart a model and a promise ought to sit.
Modelled with PVGIS v5.2, radiation database PVGIS SARAH2, meteo ERA5, reference period 2005 to 2020, horizon shadows on, at 57.153°N 2.279°W, elevation 127m, 4kWp crystalline silicon, 14% system losses, building mounted, azimuth due south.
Kilowatt hours, modelled. May is roughly six times December. This shape is the honest case for storage, and the honest case against expecting much from midwinter.
Across every page competing for this town, not one names an installer, a qualification or a single piece of equipment. Here is all three.
We are based in Peterhead and work across Westhill regularly. Saying so is better than implying otherwise. What we bring to an AB32 job is the depth on this page, and the fact that we have been on the roofs of houses very much like yours.
Anyone can claim qualifications. We will show you the certificates. Click either image to view the original document.
We fit SolarEdge, Fox ESS, Alpha ESS and SolaX, with tier 1 monocrystalline modules carrying a 25 year performance warranty. SolarEdge goes on roofs with awkward shading, because a power optimiser on each panel means a shaded module costs you that module alone rather than dragging down the string it sits in.
Every installation we complete is fully MCS registered through our Q-Smart partnership. Q-Smart is a Competent Person Scheme. Faithful Spark Electricians carries out the installation and Q-Smart issues the MCS certificate, so your system qualifies for the Smart Export Guarantee, which is paid by your electricity supplier.
A town built from 1968 onward has a very different consents profile from a granite city centre. But easy is not the same as automatic, so here is the actual position.
Solar on a house in Westhill is normally permitted development under Class 6HA of the Scottish permitted development rights, in force since 24 May 2024. The condition is that no part of the equipment protrudes more than 1 metre from the wall surface, roof plane, ridge or chimney. On a garage or outbuilding, Class 6HB applies, the limit is 500mm, and the building must not sit in the front curtilage.
Note the number, because this is where most of the advice you will read online goes wrong. Most UK solar websites quote a 200mm limit. That is the England and Wales figure and it does not apply here. Scotland's allowance is five times larger. Planning Circular 1/2024 has the detail.
Westhill's housing was almost all built from 1968 onward, so the overwhelming majority of it is modern stock with none of the designation problems that dominate a solar conversation in central Aberdeen. In practice this is one of the simplest places in the north east to fit solar.
We are not going to tell you the town has none at all, because we could not verify that and the Aberdeenshire historic environment record does hold entries carrying the Westhill name. If your property is older, or sits out towards Skene or Garlogie, check your own address on the Historic Environment Scotland portal, or ask us and we will check it with Aberdeenshire Council at survey.
You do not need a building warrant to fit solar to the roof of a single or two storey house, provided the existing roof structure can carry the additional load. That proviso is the rule, not a footnote. If the roof needs strengthening a warrant is required, and the duty to get one sits with the owner ordering the work rather than with the installer.
Given that around 90% of homes in the Westhill and Elrick zones are a house rather than a flat, the exemption is available to almost everybody here, which is not true in the city.
Your distribution network operator is SSEN. A system up to 3.68kW per phase connects under G98 and is notified to the network after commissioning. Above that, which takes in most 4kWp and larger arrays, a G99 application must be approved before the system is energised. A battery or hybrid inverter counts towards the same per phase total, so adding storage can tip a simple notification into a full application. We handle the paperwork either way. Only one competitor page targeting this town mentions G98 or G99 at all, in a single clause, and none of them names SSEN.
Part P is a section of the Building Regulations for England and Wales. Scotland has Building Standards, administered by the local council, and the mechanism is a building warrant rather than a notification. There is no Building Control body to notify.
And although Westhill sits seven miles from Aberdeen and most of the town works in it, planning and building standards here go through Aberdeenshire Council, in the Garioch area. Two authorities, two portals, two sets of designations. The pages ranking for this town blur the two routinely, and it is the sort of error that only shows up when it costs you time.
The installation is designed, tested and certified to BS 7671, the 18th Edition wiring regulations. The current amendment is A4:2026, published 15 April 2026 and mandatory for all new work from 15 October 2026. We are already working to A4. Not one competitor page targeting Westhill mentions BS 7671 at all, never mind which amendment. More on Amendment 4.
Typically four to eight weeks, most of it grid application and equipment lead time rather than anyone on your roof.
In most towns that means nothing. In Westhill it tells us the likely build era, roof geometry and board generation before we have set off.
Aspect and pitch measured with an instrument rather than assumed from the cohort, shading through the day, the structure in the loft, your consumer unit, and the cable route.
Class 6HA against your elevation, and a designation check with Aberdeenshire Council if there is any doubt about the property. On most Westhill stock this takes minutes.
Array size and layout, mounting specification, projected generation on our conservative figure, any board work, and the price. In writing, no pressure to sign on the day.
G98 notification or a full G99 application depending on total system size, remembering that a battery counts towards the same per phase total.
Usually one to two days for a domestic array, two to three with battery storage. Scaffold up first, down when the roof work is signed off.
Testing and certification to BS 7671, the MCS certificate issued by Q-Smart under our partnership, help registering with your supplier for an export tariff, and monitoring set up so you know what a normal day looks like.
The strongest ranking page for this town names no installer and no equipment. The real local firm publishes no price at all. Here is ours.
Generates 1,800 to 2,800 kWh a year. Suits a semi detached or a smaller roof, or a household with somebody home during the day.
Generates 2,400 to 3,000 kWh a year. On a six to one seasonal swing, storage is what stops a short intense summer leaking to the grid.
Generates 3,600 to 4,500 kWh a year. Westhill has a lot of large detached houses with the roof area to take it, plus heat pumps and electric cars.
0% VAT is applied automatically on qualifying residential solar and battery installations until at least March 2027. There is no VAT to add to any figure on this page.
Whether the existing consumer unit can take the new circuit, which on the earliest estates is the most common surprise. The cable run from array to board, which on a large detached house with an integral garage can be longer than you would expect. Scaffold access, which is usually straightforward here given the plot sizes. And whether an EV charger or storage is going in at the same time, which is cheaper done together than a year apart.
Unusually, nobody targeting Westhill is over claiming here, so this is short. There is no Home Energy Scotland interest free loan for solar PV or battery storage; it closed to new applications in June 2024 and has not returned. ECO4 is a heating and insulation obligation for benefit eligible households and does not fund solar for a typical owner occupier, whatever a "free solar panels" banner suggests. What genuinely exists is 0% VAT until at least March 2027 and Smart Export Guarantee income, which is paid by your electricity supplier.
Call 07304 027013We install solar and battery storage across Westhill itself, Elrick and Broadstraik, and out through Skene, Kirkton of Skene, Garlogie, Dunecht, Echt, Kingsford, Wester Ord and Kingswells.

We design and quote to 2,600 kWh a year for a south facing 4kWp array. Modelled at Westhill's own coordinates with PVGIS, the same array at a 35 degree pitch returns 3,486 kWh, and we quote below that deliberately because the model assumes a clean unshaded plane and a typical year. The figure worth knowing is the seasonal shape: around 487 kWh in May against 80 kWh in December, roughly six to one, with about three quarters of the year arriving between March and September.
Almost certainly. The modelled optimum pitch for Westhill is 43 degrees, and a standard estate roof sits around 35. The difference between them is 22 kilowatt hours a year, about 0.6%. Pitch is effectively a non issue here. What matters is which way the plane faces and what is shading it, and both of those we measure on site.
To a useful degree, yes, and Westhill is the only town we cover where that is true. It was planned from 1963 and built in bursts, so a street usually went up in one go to one developer's specification, sharing a pitch, a covering, an orientation and a plot layout. Council completion records show years of over a hundred new homes followed by years of almost none, and the council has now paused further growth pending transport work, so those cohorts stay clean. It is a strong prior, not a survey. Extensions, dormers, re roofs and corner plots break the pattern, so we still measure your actual roof.
Usually not. Solar on a house in Scotland is permitted development under Class 6HA, in force since 24 May 2024, provided no part of the equipment protrudes more than 1 metre from the wall, roof plane, ridge or chimney. On a garage the limit is 500mm under Class 6HB and the building must not be in the front curtilage. Be aware that the 200mm limit quoted on most UK solar websites is the England and Wales rule and does not apply here. Westhill's housing is almost all post 1968, so designation problems are rare, but check your own address if the property is older.
A 3kWp to 4kWp solar only system is £7,000 to £8,500 fully installed. A 4kWp system with a 10kWh battery is £10,000 to £12,000. A 6kWp system with 10kWh or more of storage is £12,000 to £15,000. Battery retrofit to an existing array is £3,500 to £5,000. All carry 0% VAT until at least March 2027, so there is nothing to add. Locally, the most common thing that shifts the price is whether the existing consumer unit can take the new circuit.
Not for a single or two storey house, provided the existing roof structure can carry the extra load. If the roof needs strengthening a warrant is required, and the duty to obtain it sits with the owner ordering the work. The exemption does not extend to flats or maisonettes, but around 90% of homes in the Westhill and Elrick census zones are a house or bungalow rather than a flat, so it is available to almost everybody here.
Aberdeenshire, in the Garioch area, despite sitting about seven miles west of Aberdeen and most of the town working in the city. It matters practically, because planning, building standards and conservation designations all go through Aberdeenshire Council rather than Aberdeen City, and they are separate authorities with separate portals. Several pages ranking for solar in this town blur the two.
It works, but the seasonality is severe and you should plan around it rather than be surprised by it. Modelled at Westhill's coordinates, a south facing 4kWp array produces around 487 kWh in May against around 80 kWh in December, a six to one swing. Roughly three quarters of annual generation arrives between March and September. A battery shifts a summer afternoon into a summer evening. It cannot shift June into December, and anyone suggesting year round independence is overselling.
It depends on when your household actually uses electricity, not on the panels. Solar generates through the middle of the day, and whatever the house does not use in that moment goes to the grid for roughly half what you would pay to buy it back. If the house is empty on weekdays, storage is where most of the value sits. Given the seasonal shape here, a battery is best understood as a way to capture a short intense summer rather than as winter insurance.
SSEN. A system up to 3.68kW per phase connects under G98 and is notified after commissioning. Above that, which covers most 4kWp and larger arrays, a G99 application must be approved before the system is energised. A battery or hybrid inverter counts towards the same per phase total, so adding storage can tip a simple notification into a full application. We handle it either way.
No. The Home Energy Scotland interest free loan for solar PV and battery storage closed to new applications in June 2024 and has not returned. ECO4 is a heating and insulation obligation aimed at benefit eligible households and does not fund solar for a typical owner occupier, whatever a "free solar panels" promotion implies. What genuinely exists is 0% VAT on the installation until at least March 2027, and Smart Export Guarantee income on what you export, which is paid by your electricity supplier.
No. Part P is a section of the Building Regulations for England and Wales. Scotland has Building Standards, administered by the local council, and the mechanism is a building warrant rather than a notification. There is no Building Control body to notify here. For Westhill that council is Aberdeenshire, not Aberdeen City.
Call Steven directly on 07304 027013 or use the form. In most towns the street name tells an installer nothing. In Westhill it tells us the likely build era, the roof geometry and the generation of consumer unit behind the door, before anybody sets off. Then we measure it properly and put a fixed price in writing.
