Helping Colchester Clients Meet Building Regulations Part L1A and L1B
Working across Essex, including Colchester, we specialise in the assessment of existing and new buildings for Building Regulations Parts L1A and L1B.
You might not realise it but it's already vitally important to have your Colchester building assessed by experienced professionals. However, with building regulations relating to energy efficiency and air leakages getting stricter year by year, it is now of paramount importance.
In fact, building regulations across Colchester and Essex are now set so low that innovative and new designs and technologies are required to ensure that the new dwellings pass.
At Tophouse Assessments, we combine full qualifications and certifications with decades of experience and expertise to accurately assess your Colchester building design to the very latest building regulations Part L. We also work closely with architects and designers from the initial stage of the project to ensure the building complies.
We work across Essex and Colchester, so call our experienced and qualified team today on 01634 799115 for free building regulations Part L advice and a no obligation quotation.
What is Building Regulations Part L?
Part L of the Building Regulations deals with the conservation of fuel and power. There are four approved documents;

Part L1a for new dwellings (flats and houses)

Part L1b applies to work on existing dwellings or buildings converted to dwellings

L2a applies to new commercial buildings

L2b applies to existing commercial buildings
Providing A Full Compliance Checklist
As part of all current building regulations, you are required to provide the local authority in your area with a full compliance notice no later than one day before the building work is due to commence. This should include:
- The target emission rate and fabric energy efficiency for the building
- An evaluation of alternative high energy efficiency systems
- The calculated CO2 emission rate and fabric energy efficiency from the building as designed
- A list of specifications to which the dwelling is to be constructed
