Construction Drawings near you

A full plans application deposits the drawings for assessment before work starts. GOV.UK describes it as the most thorough option, says you can expect a decision within five weeks or two months with your consent, and says you will typically receive a completion certificate within eight weeks of the work being completed provided it meets the regulations. The advantage is that the detail is agreed before anybody builds it, which is what you want on anything structural or unusual.

A building notice is for smaller projects only. You can start work two days after the notice has been submitted to your building control body, and there is no formal approval of drawings. It suits simple, well-understood work with a builder who knows the regulations, and it is a poor choice on anything where an argument about the detail would be expensive to resolve on site.

There is a third route for work already done. GOV.UK says you can apply for regularisation — retrospective approval for work already carried out without consent — from a local authority building control body only, and only for work completed after 11 November 1985. You may need to open up or alter the work before approval is given, and you may have to correct the work or pay a fine if the regulations were not followed.

In England and Wales there are two kinds of building control body and you choose between them: your local authority's building control service, or a private registered building control approver. Higher-risk buildings go to the Building Safety Regulator instead, which GOV.UK defines by criteria including 7 or more storeys or 18 metres or more in height with at least two residential units, along with hospitals and care homes.

The individuals doing the assessing are now regulated as well. GOV.UK guidance states that after April 2024, anyone intending to carry out regulated building control activities in England or Wales — assessing plans, carrying out inspections, or giving advice to building control bodies that carry out regulated functions — must be registered as a building inspector, and that after that date it is a criminal offence to work as a building inspector without being registered. The Building Safety Regulator maintains separate public registers for England and for Wales.

Registration is by class and category. Class 1 inspectors must work under supervision and no competency assessment is required; class 2 covers unsupervised work on standard buildings in categories A to F; class 3 covers unsupervised work including non-standard buildings in categories A to H; and class 4 covers technical managers who are class 2 or 3 with additional responsibilities. For a householder, the useful consequence is that you can check whether the person assessing your drawings is registered for the kind of building you are altering.

Scotland uses a building warrant rather than an application to a building control body. The council's building standards department assesses the application and grants the warrant before work starts, and mygov.scot lists the work that needs one: building a new home, extending a home, building or removing load-bearing walls, changing roofs, external walls or other structural elements, converting a loft or garage into a room, and demolishing a building. It is an offence to start building work without a warrant when you need one, and you could be fined.

A Scottish warrant comes with paperwork you will not see in England: the warrant itself, a copy of the approved plans, and a Construction Compliance and Notification Plan setting out the stages at which the council must be notified. The warrant is valid for three years from the date it was granted, and the work should be completed within that time. The 32 local authorities are appointed as verifiers by Scottish Ministers for their own areas, so there is no private route equivalent to a registered building control approver.

Northern Ireland works to the Building Regulations (Northern Ireland) 2012, made by the Department of Finance and administered by 11 district councils, each with a statutory duty to enforce the regulations in its area. The regulations require formal notice to the district council when work is completed, and Building Control issues a certificate of completion once satisfied that the regulations have been met.

The fee for a technical package tracks the number of details that have to be resolved rather than the floor area. A simple rear extension using standard construction needs a handful of sections and details; a conversion touching fire separation, sound insulation, structural alteration and new drainage needs many more, plus coordination with the engineer. Other variables are whether the set is produced for a full plans application or only for the builder, whether the fee includes answering building control queries and issuing revisions during construction, and whether a specification is written or left to the drawings. Ask which of those are inside the fee, because query responses and revisions are the usual extras.

LokalMatch is the introduction and stops there. Describe the drawings you need once with your postcode, and technicians, designers and practices covering your area will contact you. Homeowners pay nothing to use it; the professionals pay for the enquiries they receive. LokalMatch does not produce drawings, does not set fees and does not vet, rank or recommend anyone who responds, so compare the deliverables list before you compare the prices.
