Local to Blyth
Across NE24, we can visit, measure and advise. Neighbouring towns we cover include Bedlington (3 miles), Ashington (4 miles), Cramlington (4 miles), Morpeth (8 miles).
Just over the Tyne and Wear border, Whitley Bay is about 7 miles away. Across the North East, houses often have rear yards or modest gardens, so compact, well-lit single-storey extensions make the biggest difference.
What it costs in Blyth
These are guide fees for Blyth, adjusted for North East England (×0.91) and including VAT. Council application and inspection fees are paid separately.

Do I need planning permission in Blyth?
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.
If the work involves a shared wall, building on the boundary, or digging foundations within 3 m (sometimes 6 m) of a neighbour's building, the Party Wall etc. Act 1996 applies and notice must be served before work starts: two months for work to a party wall, one month for new walls on the boundary and for excavations.
Applications are decided by the local planning authority (your district, borough or unitary council).

Questions answered
Who do I contract with in Blyth?
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 this take for a Blyth home?
2–5 weeks for drawings, depending on the council and the complexity of the project.
Do you cover all of Blyth?
Yes. We cover Blyth and the surrounding parts of Northumberland. Site visits are free and there is no obligation.
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.
