Planning rules that apply in Wrexham
Building regulations approval is separate from planning. Wales has its own building regulations and approved documents; the council or a registered building control approver checks the plans, inspects the work and issues 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.
The Party Wall etc. Act 1996 applies in Wales as in England: notice must be served before work to a shared wall, building on the boundary, or excavating close to a neighbour's foundations.
Applications are decided by the local planning authority (your county or county borough council, or the national park authority).

Our survey diary covers Wrexham, including LL11, LL12, LL13. The same team covers Rhosllannerchrugog (4 miles), Buckley (9 miles), Hawarden (10 miles), Deeside (11 miles), all within easy reach.
Welshpool, in Powys, is roughly 28 miles from Wrexham and also on our list. In Wales, terraced houses with rear offshoots are common in the towns, while detached houses and bungalows dominate in rural areas.

Questions answered
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Wrexham, 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 in Wrexham?
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 Wrexham?
Yes. We cover Wrexham and the surrounding parts of Clwyd. 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.
Who are building control?
Either your local council’s building control team or a registered building control approver. Both inspect the work and issue the completion certificate.
