Certificates & Accreditations

A strong and sustainable green focus is at the heart of Howarth Timber Engineered Solutions. We understand our responsibility to reduce the impact our business has on the environment.
As a Chain of Custody holder, we are committed to using timber certified by the Programme for the Endorsement of Forest Certification scheme (PEFC) or the Forest Stewardship Council® (FSC)®.

This is an assurance to our customers that we are procuring from environmentally responsible suppliers. At all points in the process, from source and shipping to production and delivery, Howarth Timber Engineered Solutions can provide full Chain of Custody certification covering the entire product range, thereby achieving complete traceability.

Alongside our Chain of Custody accreditation, Howarth Timber Engineered Solutions supports responsible sourcing through the major timber certification schemes. We comply with government specifications for legal and sustainable sources and can satisfy the requirements of third party audit organisations used within the construction industry. We operate CoC certification under the PEFC and FSC® schemes.

  • TTF - Timber Trade Federation

    The TTF represents the timber industry in the UK as its Trade Association. The TTF represents the views and interests of its members to civil servants, politicians, regulators and other key individuals and organisations (including NGOs) locally, nationally and internationally (particularly at EU level).
  • Responsible Purchasing Policy (RPP)

    The Timber Trade Federation, in 2010, introduced new environmental criteria in the Code of Conduct to help members prepare for the EU Timber Regulation. This new criteria committed all members to implement an Environmental Due Diligence System from 2010 onwards, the TTF's Responsible Purchasing Process (RPP) or equivalent.


    Provides a framework to analyse the risk of illegal timber entering into their supply chains. Introduces a phased approach to progressively source increasing proportions of timber products from credible and verified legal and sustainable sources; and supports members in promoting good practice procurement policies to customers.


    The RPP is complementary to certification schemes like the FSC® and PEFC. Standard forms and questionnaires enable buyers and suppliers to provide the information required in a formal and systematic way. The TTF provides technical expertise and guidance to support members to implement the RPP.

  • TRA – Trussed Rafter Association

    The TRA is the respected voice of the trussed rafter and metal web joist industry in the UK. The Association is committed to stringent standards of quality and service and sets a professional benchmark for the industry. Members include the principal manufacturers of trussed rafters, metal web joists, suppliers and professionals involved in roof and floor design and construction. The TRA requires all its manufacturing members to have third-party supervised Quality Assurance and Professional Indemnity insurance so helping to ensure quality and peace of mind for the customer.
  • HBF – Home Builders Federation

    The HBF is the voice of the home building industry in England and Wales. Its members deliver around 80% of the new homes built each year, representing member interests on a national and regional level to create the best possible climate in which they can deliver the homes this country needs.


    HBF members range from household multinational names to smaller local businesses, and include RSL’s, suppliers and companies who provide professional services to the home building industry.

  • PEFC™ Chain of Custody

    The Programme for the Endorsement of Forest Certification Schemes™ (PEFC™) is an international forest certification system. It is the world’s largest organisation for ensuring and continuously improving sustainable forestry while guaranteeing compliance with ecological, social and economic standards. To ensure that small family forestry operations could obtain certification, PEFC™ chose a regional approach based on local workgroups and forestry reports.


    Forestry operations in the respective regions are audited on a sampling basis at regular intervals. At the same time, the new objectives for the continuous improvement of sustainable forest management while guaranteeing compliance with ecological, social and economic standards are established.

  • FSC® Chain of Custody

    The Forest Stewardship Council® was formed in 1993 as an international organisation and supported by environmental associations such as the WWF, woodlot owners, the timber industry, unions and indigenous peoples to help control the destructive exploitation of forests.


    The FSC® is independent and does not pursue any financial interests. Its objective is to identify wood from socially and environmentally friendly forestry with a seal of approval. In order to guarantee this; independent experts inspect wood annually within the scope of certification.

  • ISO 9001:2008

    As the international benchmark for Quality, this standard delivers a best practice Quality Management System (QMS) that helps organisations to demonstrate to customers and stakeholders that quality assurance is of paramount importance to their business.


    ISO 9001:2008 sets out the criteria for a Quality Management System and is based on a number of quality management principles including a strong customer focus, the motivation and implication of top management, the process approach and continual improvement.


    Checking that the system works is a vital part of ISO 9001:2008. The organization must perform internal audits to check how its quality management system is working and is audited regularly by an independent third party Certification Body to verify that it is in conformity to the standard.

  • CHAS – Contractors Health & Safety Assessment Scheme

    In 1997 a group of health and safety and procurement professionals from across Great Britain worked with the Association of London Government (ALG) to develop CHAS.


    CHAS started with two main aims. 1. To improve health and safety standards across Great Britain. 2. To reduce duplicated safety applications for both suppliers and buyers.


    Each month thousands of contractors and consultants (suppliers) apply for work with public and private sector organisations (buyers). To win work, they must meet the buyer’s health and safety standards. However, assessing supplier’s health and safety competence is usually a lengthy and time consuming process. Suppliers can sometimes meet one buyer’s Health and Safety standards but not another. Being CHAS approved reduces duplication as suppliers compliance is accepted by all CHAS buyers.
  • SMAS – Safety Management Advisory Service Scheme

    Many Clients will now only use contractors and consultants selected from an approved database who have demonstrated the appropriate level of competence in their H&S management systems. Clients can be assured that contractors and consultants who have been assessed and accredited by an SSIP member scheme have achieved the initial threshold of competence to provide specific services.


    In line with the SSIP Terms and Conditions, SMAS will use the Construction (Design and Management) Regulations 2007 “core criteria” or the health and safety module in PAS91 as its threshold requirement.


    SMAS Ltd is a Registered Member of the Safety Schemes in Procurement (SSIP) Forum. The SMAS Worksafe certificate should be recognised by many other SSIP member schemes – meaning that your organisation should not have to complete further full Health & Safety assessment questionnaires for SSIP member schemes (who offer mutual recognition), whilst your certificate remains valid.
  • CE Marking

    The Construction Products Regulation (CPR) breaks down technical barriers to trade of construction products within the EU so that similar products can be compared to each other and freely traded. It replaces the CPD which has been in place for many years but it has been only voluntary to CE Mark in the UK under this directive. The CPR came into force on 1st July 2013. From this date wood and wood products destined for the construction market and covered by a harmonised European Standard (hEN) or European Technical Approval (ETA) are required to declare their performance characteristics via CE Marking in order to be placed on the UK and EU construction products markets.


    To reflect the new CPR, Section 7 of the UK Building Regulations is also being amended to adopt CE Marking as the primary route to show fitness for purpose in the UK. CE Marking is now built into the Building Regulations as the preferred choice to meet Regulation 7 which stipulates that building work shall be carried out with adequate and proper materials. Products produced by Howarth Timber Engineered Solutions Limited that require CE Marking are Trussed Rafters, covered by BS EN 14250:2010, and Posi Joists (Metal Web Joists), covered by European Technical Approval ETA-07/0161 and are in full compliance with the CPR.


    The Declaration of Performance (DoP) and Factory Production Control certificates (FPC) for both Trussed Rafters and Posi Joists (Metal Web Joists) produced by Howarth Timber Engineered Solutions Limited are available to download in PDF format.
