Being a Member of Build UK

Anna Wesson, INCA Manager

As you may know, INCA is a member of Build UK. This is the Trade Association that represents over 40% of the construction industry in the UK.

There are lots of benefits to being a member of Build UK. It is an association with a lot of influence, working on some really important projects that affect the whole of the sector. External Wall Insulation (EWI) is no exception – Build UK projects do, and will affect your work.

In order to give a flavour of some of the work that Build UK does, here is a summary of two of the major projects:


It is widely recognised that currently the pre-qualification system is a bureaucratic and repetitive process. The construction industry need a method of pre-qualification that meets the needs of clients and other stakeholders and is beneficial to the construction supply chain. Build UK aims to deliver this. This ambitious project is due to deliver in summer 2018.


It isn’t news that fair and transparent payment practices are essential for a successful construction industry. Getting it right means having a strong and sustainable supply chain capable of meeting clients’ needs.

Build UK is bringing together the contracting supply chain to consider what best payment practice in construction looks like. Clearly that means looking into alternatives to the current retentions practice, and getting all parts of construction involved in coming up with and taking on alternative practices. The potential when this lands is huge, and will impact the EWI industry. Being a Build UK member gives INCA members the opportunity to shape policy and be at the forefront of implementing it.

Get Involved

Build UK needs your help as Trade Association members for these projects to meet your needs. There is huge opportunity to get involved on committees, through conversations with the team, or through feeding back through INCA. As INCA Manager, I will keep you updated over the coming months with how the projects progress.

Wind Load Guidance

Mitch Gee, Executive Chairman

It is of no surprise that wind load is high on the agenda of INCA. The issue has come up time and again, and is something that we, as the Trade Association representing the EWI Industry, are fully engaged with.

The Secretary of State for Communities and Local Government, Sajid Javid, made the following statement when updating the House of Commons about Grenfell:

‘’Separately, the British Board of Agrément has told us that, based on its investigations following incidents in Glasgow, some cladding systems may have been designed and installed in such a way that they could fail in strong winds. We are not aware of any injuries caused by this kind of failure. However, we are taking advice from the independent expert panel and we have written to building control bodies to draw their attention to the issues that have been raised. The wider issues of competence and certification will also feed into Dame Judith Hackitt’s review of building safety, the terms of reference of which were announced last week. Finally, I have established an Industry Response Group, which will help the sectors required to improve building safety and to co-ordinate their efforts.’’

INCA is in discussions with the BBA over how best the industry can manage this situation. Wind Load Guidance also came up when we met with BEIS in October. We explained that external wall insulation has been used on high rise blocks for over 25 years, with very few known failures, and no evidence that EWI has suffered any greater degree of failure than any other cladding system. Furthermore, there is no evidence that the calculation of wind loads has contributed to any of these failures. Notwithstanding this, the BBA have identified an area of system design that can be improved, and post Grenfell it is important that responsibility for design is clearly established. INCA is working on a response to ensure where it is warranted by risk, an appropriate system is in placed among INCA member system holders to provide the necessary calculations.

In relation to legacy work, INCA believes there is a responsibility for owners of high rise buildings to have a responsibility to undertake regular maintenance checks on any cladding on high rise building. No cladding system has an indefinite life and such maintenance is essential to prevent the risk of catastrophic failure, irrespective of the type of cladding used. INCA’s technical committee will be considering what advice can be given to owners of high rise buildings that are clad with external wall insulation. The results of these considerations will be forwarded to all members.

Making Sense of the Clean Growth Strategy

Clean Growth Strategy

INCA Executive Chairman, Mitch Gee

Government’s Clean Growth Strategy

The government published its Clean Growth Strategy on the 12th October 2017. An exciting and ambitious document, it sets out plans for cutting greenhouse gas emissions without impacting on Gross Domestic Product (GDP) – in fact, contributing to growth in GDP whilst ensuring affordable energy.

The Climate Change Act committed the country to reduce greenhouse gasses by at least 80% by 2015 when compared to 1990. The government has good reason to be pleased with itself as we have managed to cut emissions by 42% since 1990, while the economy has grown by 67%. It may be argued that the low hanging fruit has been plucked, with 21% of these reductions from the power industry, which has benefited from the switch of solid fuel to gas. With further enhancement from renewable energy this looks set to continue.

There has been a contribution from household energy where carbon emissions have fallen by 17%. This is reasonably impressive considering the number of homes has increased by approximately a quarter. Unfortunately so far, this has only contributed to a 3% reduction in carbon emissions since 1990, but it is important to remember the emissions created by heating our homes is 13% of all emissions. Focusing on homes gives a triple blessing in reducing emissions, lowering bills and creating healthier homes. The Government recognises there is a direct link between cold, damp homes and ill health. The Building Research Establishment has estimated that these homes cost the NHS £760 million per year. We can already count the financial benefit of the policy in this area. In 2016 the costs per household of the current policy was £147, with the average household benefit being £161.

How will the Clean Growth Strategy drive the market for external wall insulation (EWI)?

There are a number of elements of the strategy that will have a positive impact on our industry:

  • The UK has led the way in developing green finance. The strategy includes working with mortgage providers to develop green mortgage products that take account of lower lending risk and enhanced repayment associated with more energy efficient properties.
  • There is £3.6 billion of investment to improve the efficiency of a million homes and extend support for Energy Company Obligation (ECO) until 2028.
  • It is the governments’ ambition to up-grade all fuel poor homes to a minimum Energy Performance Certificate (EPC) of C by 2030, and where practical, all homes by 2035.

Looking further ahead, the government identifies a need to consult on strengthening energy performance standards for new and existing homes under building regulations. The strategy will continue to develop, and one of the next steps will be making the private rented sectors’ energy efficiency regulations more effective, setting longer long-term energy performance standards. Claire Perry, Minister of State at the Department for Business, Energy and Industrial Strategy has stated that the government were looking at a ‘carrots and sticks’ approach and may be considering linking stamp duty with the energy efficiency of homes.

The Clean Growth Strategy will have a positive impact on the macro economy, influencing the uptake of solid wall insulation. However, without greater incentives and an increased focus on the hard to treat homes within ECO, it may remain a slow burner. EWI may not be impacted until late in the cycle.

If you have an opinion on the strategy then we would be pleased to hear it.
