Working in Fort William
Postcode districts we cover around Fort William include PH33. Island and remote projects are planned individually, with travel, deliveries and accommodation for the team agreed before the survey.
Across Scotland, extensions follow Scottish planning and building standards, including the building warrant process, which we build into the programme from the start.
When a conservatory replacement makes sense
- Older uPVC conservatories near the end of their life
- Homes where the conservatory sits unused
- Conservatories that are too hot or too cold
A replacement is a chance to rethink the shape. Many conservatories are oddly proportioned; for a similar cost the new room can often be squarer, wider or better connected to the kitchen.

Do I need planning permission in Fort William?
In Scotland, householder permitted development rules (Class 1A for single-storey ground-floor extensions and Class 1B for extensions of more than one storey) allow some smaller extensions without a planning application, within limits on depth, height and distance from the boundary. Conservation areas and listed buildings are more restricted. Separately, almost every extension needs a building warrant from the council before work starts.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
Scotland has no Party Wall Act. Where work affects a shared wall or a neighbour's land, we agree access, protection and making good with your neighbour in writing before work starts.
Building close to a public sewer needs the agreement of Scottish Water, which we check during design.
Applications are decided by your council as planning authority.
From first visit to completion
Visits to Fort William are arranged around travel; we confirm any travel costs in writing before the survey.
Site visit by arrangement
First, a site visit: we look at the house, garden, access and drains and listen to what you need.
Design and approvals
We draw the design, agree it with you and handle planning or permitted development checks and building regulations.
Fixed written price
With the design and specification agreed, you get a fixed written price and a start date.
Build and sign-off
We build it with one project manager, book the building control inspections and hand over the completion certificate.
Conservatory replacement questions answered
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Fort William, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Who do I contract with for a conservatory replacement in Fort William?
Your contract is with S&K Property Investments and Improvement Ltd, which designs and manages the project and the build teams who carry it out.
How long does a conservatory replacement take to build in Fort William?
On site, typically 8 to 14 weeks once approvals are in place. Before that, allow 4–12 weeks design and approvals.
Is it worth replacing a conservatory with an extension?
If the conservatory is unusable for much of the year, usually yes. A solid extension gives a heated room that counts as proper living space. Our guide range is about £1,810 to £3,430 per m² including VAT, including removal.
Does replacing a conservatory need planning permission?
A solid replacement is treated as a new extension, so it must meet the permitted development limits or get planning permission, and it always needs building regulations approval.
