Planning rules that apply in Luton
Building regulations approval is separate from planning. In England you can use the council's building control team or a registered building control approver; a full plans application gets the drawings checked before work starts, and the inspector signs the work off with a completion certificate.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.
Applications are decided by the local planning authority (your district, borough or unitary council).
Extensions in and around Luton
Across LU1, LU2, LU3, LU4, LU5, LU6, we can visit, measure and advise. Nearby, we also take on projects in Dunstable (5 miles), Leighton Buzzard (11 miles), Ampthill (11 miles), Kempston (17 miles).
Harpenden, in Hertfordshire, is roughly 5 miles from Luton and also on our list. The East of England mixes market-town terraces, inter-war semis and modern estates. Clay soils are common in parts of the region, which can affect foundation design.

Who this service is for
- Glass-heavy designs that need energy calculations
- Every extension, whatever the planning route
- Homeowners using their own builder who need the drawings
Building regulations approval and planning permission are separate. A design can have planning consent and still need changes to meet the regulations, which is why we draw for both together.

Common questions in Luton
Who do I contract with in Luton?
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.
Do you cover all of Luton?
Yes. We cover Luton and the surrounding parts of Bedfordshire. Site visits are free and there is no obligation.
Will my neighbours in Luton be involved?
If a planning application or prior approval is needed, the council notifies neighbours. If the work is on or near a shared boundary, party wall notices may also be needed.
Full plans or building notice?
A full plans application gets the drawings checked before work starts, which we usually recommend for extensions. A building notice is quicker to submit but carries more risk if something needs changing on site.
What are the insulation standards for an extension?
In England, new walls in an extension should achieve a U-value of 0.18 W/m²K, roofs 0.15 and floors 0.18, with windows at 1.4 and rooflights at 2.2. Wales, Scotland and Northern Ireland set their own figures.
