Overview
Sureserve is a United Kingdom-based group whose business is focused on energy services, property compliance and related regeneration work. The company serves social-housing providers, local authorities, education organizations, public-sector bodies and commercial building owners. Its activities include gas and heating compliance, fire and life-safety compliance, water and air hygiene, energy efficiency, smart metering, renewable-energy installations, electric-vehicle charging infrastructure, lifts compliance and associated maintenance services. The business was founded in 1988 and was originally known as Lakehouse. During the Lakehouse era, it expanded through a series of acquisitions intended to broaden its technical capabilities and geographic reach. Acquired businesses included K&T Heating in gas compliance, Allied Protection in fire compliance, Foster Property Maintenance, Everwarm in energy services, H2O Nationwide in water and air compliance, Providor in smart metering, Orchard Energy in energy brokerage and management, Sure Maintenance and Aaron Heating in gas compliance, and Precision Lifts in lift compliance. This acquisition-led model gave the group a portfolio spanning several regulated and infrastructure-related services rather than a single trade. Lakehouse floated on the London Stock Exchange in March 2015. Its public-company period was subsequently affected by portfolio restructuring, operational challenges and scrutiny connected with historic contracts. In 2018, the group sold its construction and property-services operations, Lakehouse Contracts, to a newly formed company, Mapps Group. The parent changed its name from Lakehouse to Sureserve Group in October 2018, separating the continuing group from the business that retained the Lakehouse trading identity. Lakehouse Contracts later entered administration, and Sureserve recognized provisions and wrote down the consideration associated with the disposal. The company’s history also intersected with public scrutiny following the Grenfell Tower fire. Its Allied Protection business had been engaged by the Royal Borough of Kensington and Chelsea in January 2017 to certify fire-safety systems installed at Grenfell Tower. The company was also associated with a Metropolitan Police fraud investigation concerning two historic Lakehouse-Hackney Homes contracts; the available account states that Lakehouse cooperated with the investigation and that there was no suggestion of fraud by Lakehouse itself. After a period under public ownership, Sureserve was acquired in 2023 by Cap10 Partners through a recommended all-cash takeover and became Sureserve Group Ltd. Graham Levinsohn became executive chair and chief executive after the transaction. The privately owned group then resumed expansion, agreeing the acquisition of Swale Heating in 2023 and Duality Group in 2024. In 2025, it agreed to acquire Kinovo, a competing provider focused on electrical safety and maintenance. These transactions indicate a continuing strategy of consolidating specialist compliance and energy-service capabilities in the UK housing and built-environment markets. As described in the reference material, Sureserve had approximately 2,756 employees and operated through 33 UK offices in May 2023. Its competitive proposition is based on delivering technically regulated services at scale, often under long-term arrangements with social landlords and public-sector customers. The group’s work sits at the intersection of housing maintenance, decarbonization, statutory compliance and building safety.
History
Sureserve traces its origins to 1988 and operated for most of its earlier history under the Lakehouse name. The group developed as a UK provider of property, energy and compliance services, concentrating on customers such as social landlords, local authorities and public-sector estates. Between 2011 and 2015 it acquired ten complementary businesses, adding gas, fire, property-maintenance, energy, water, air, metering, energy-management and lift-compliance capabilities. The acquisition of K&T Heating in 2011 expanded gas-compliance services, while Allied Protection added fire compliance in 2012. Foster Property Maintenance followed in 2013. In 2014 the group acquired Everwarm, an energy-services provider that also worked on solar photovoltaic systems and electric-vehicle charging infrastructure, together with H2O Nationwide, which specialized in water and air compliance. In 2015 Lakehouse added Providor, Orchard Energy, Sure Maintenance, Aaron Heating and Precision Lifts. This portfolio positioned the group as a multi-disciplinary contractor in regulated housing and building services. Lakehouse became a listed company on the London Stock Exchange in March 2015. Its later history included a major reshaping of the business. Allied Protection was reported to have certified fire-safety systems at Grenfell Tower for the Royal Borough of Kensington and Chelsea in January 2017, before the tower was destroyed by fire on 14 June 2017. The company’s historic activities also became connected with a fraud investigation involving two Lakehouse-Hackney Homes contracts covering work carried out in 2013 and 2014. Ten people were charged in 2018; the company said it was cooperating, and the referenced account does not allege that Lakehouse committed fraud. In August 2018, Lakehouse sold its construction and property-services division, Lakehouse Contracts, which employed 236 people, to newly formed Mapps Group for £500,000. The parent company changed its name to Sureserve Group plc on 1 October 2018. Lakehouse Contracts continued to trade under the Lakehouse name but entered administration in March 2019. Sureserve first set aside £2.5 million for potential claims and later reported £5.4 million of provisions following the disposal and collapse. These events marked a transition away from the group’s broader construction and property-services configuration toward its continuing energy and compliance businesses. Bob Holt stepped down as chairman and chief executive in March 2021. Peter Smith became chief executive in November 2021. In 2023, Cap10 Partners launched a recommended all-cash takeover valued at £214 million in the reference material. The transaction took Sureserve private and created Sureserve Group Ltd. Graham Levinsohn was appointed executive chair and chief executive in July 2023. Under private ownership, Sureserve continued to expand through specialist acquisitions. It agreed to buy Swale Heating in November 2023, adding heating capabilities across southeast England, London and East Anglia. In April 2024, it acquired Duality Group, whose companies install and maintain energy services for residential and commercial markets. In May 2025, Sureserve agreed a £56.4 million acquisition of Kinovo, a business with reported turnover of £64 million and a focus on electrical safety and maintenance. The group therefore remains oriented toward consolidating UK energy, compliance and building-maintenance services.

Products and positioning
A UK specialist in regulated energy, building-compliance and maintenance services, with a strong emphasis on social housing, public-sector estates and other regulated customers.
Energy and decarbonization
Energy services
Sureserve provides energy-related services for residential, public and commercial properties. These include energy-efficiency work, energy management, smart metering and renewable-energy installations. The group’s historic portfolio also included solar photovoltaic systems and electric-vehicle charging infrastructure, linking its housing-services work with building decarbonization and changing energy requirements.
Building and property compliance
Compliance services
The compliance portfolio covers regulated building systems and safety obligations. Services have included gas and heating compliance, fire and life-safety systems, water and air hygiene, and lift compliance. These activities are particularly relevant to social landlords and public-sector organizations that must maintain large, dispersed property portfolios and demonstrate statutory compliance.
Mechanical services
Heating and maintenance
Through its heating businesses and later acquisition of Swale Heating, Sureserve provides heating solutions and related installation, servicing and maintenance. The service footprint described in the reference material includes southeast England, London and East Anglia, alongside the group’s broader UK public-sector and housing activities.
Property services
Regeneration and construction services
Regeneration and construction formed part of the group’s historical scope, including the Lakehouse Contracts operation. That operation was sold in 2018 and later entered administration, so this area should be treated as historical rather than a confirmed core activity of the current Sureserve Group.
Controversies

Hackney Homes contract fraud investigation
Ten people were charged in connection with a fraud investigation concerning two contracts between Lakehouse and Hackney Homes for work carried out in 2013–2014.
