WHAT IS A HTT CAVITY?
The Cavity Insulation Guarantee Agency
What is a HTT Cavity?
• Term coined by DECC to identify properties that are
more difficult to treat for technical or cost reasons.
• Higher costs means that they were not treated in
earlier Supplier Obligations.
• Extending benefits of CWI to householders in hard to
treat properties is a Particular focus of the Energy
Company Obligation (ECO) and Green Deal.
– HTT Cavities a primary measure under CERO
• Defined in “The Electricity and Gas (Energy Companies
Obligation) Order 2012” Statutory Instrument.
• Further Guidance included in the OFGEM “Energy
Companies Obligation (ECO) 2012 - 2015: Guidance for
Suppliers”

The HTT Opportunity - Si
• (i) 3 or more storeys where each storey has cavity
walls;
• (ii) which a chartered surveyor has reported is not
suitable to insulate with standard insulation material or
techniques;
• (iii) which a chartered surveyor has reported is not
suitable to insulate without substantial remedial works;
• (b) a cavity within a cavity wall which is less than
50mm wide;
• (c) a cavity found in homes of prefabricated concrete
construction or with metal frame cavity walls; or
• (d) an uneven cavity formed in walls constructed of
natural stone or from natural stone outer leaf and
block or brick inner leaf;

The Cavity Insulation Guarantee Agency
HTT - Examples
• 3 or More Storeys
• Requiring substantial Remedials (4 hours)
• <50mm cavities
• Cannot treat with Standard Products or Techniques
– High Exposure/WP risks
– Timber Framed
– Partial Fill
• Steel or Concrete Frame
• Random Stone.
The Cavity Insulation Guarantee Agency
Identification -GD Assessment
• RdSAP covers 3 issues in relation to hard-to-treat
flaged on EPC – access, narrow cavity and exposure:
– Access issue is indicated for any façade where it is
not possible to safely pitch a 5 metre.
– A narrow cavity is indicated by a stretcher bond
brick pattern with wall thickness 220 to 250 mm.
– Exposure zones 3 or 4.
• Includes cases where at least 1 elevation is HTT.
• BUT:
– Does not map to ECO HTT definitions.
– Does not capture main addressable markets ie
remedials & Non Standard Techniques and Materials

3 or More Storeys
• A building of 3 or more storeys of cavity wall is HTT.
• Includes basement with external wall exposed to the
air but excludes Lofts.
• Buildings up to 12m can filled under current approvals.
• In the case of buildings over 12m System Designer must
have a BBA approved procedure to issue height waivers
and additional CIGA requirements apply for issue of
