Local to Kelso
Site visits are available across Kelso (TD5). Neighbouring towns we cover include Galashiels (16 miles), Hawick (19 miles), Peebles (31 miles).
Scotland's housing includes sandstone villas, terraces and tenements in the cities and plenty of post-war and modern houses and bungalows elsewhere. A building warrant is needed before work starts.
Planning rules that apply in Kelso
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.
The planning position for a specific Kelso address depends on its history and any designations, which is why we check it at the first visit.
In Scotland a building warrant from the council is needed before work starts on almost any extension, and a completion certificate is issued when the work is accepted. Building standards are set in the Scottish technical handbooks.
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.

When a utility room extension makes sense
- Houses with a side passage or small rear corner
- Kitchens that have run out of space for appliances
- Busy family homes
A good utility works like a back-of-house corridor: in from the garden, boots off, coats on hooks, washing on the way through. We plan the door positions so it doesn't become another room to walk around.

Utility room extension questions answered
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Kelso, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Do you cover all of Kelso?
Yes. We cover Kelso and the surrounding parts of Scottish Borders. Site visits are free and there is no obligation.
Do I need building regulations approval in Kelso?
Yes. Almost every extension needs it, whatever the planning route. In Scotland that means a building warrant before work starts.
How much does a utility room extension cost?
Our guide range is about £1,860 to £3,430 per m² including VAT, with a minimum of around £14,000. An 8 m² standard-spec utility is typically £17,500 to £22,000 in Kelso.
Does a utility extension need planning permission?
Often not, if it is single storey and within permitted development limits. We check this for your property.
