Annual boiler servicing and landlord CP12 gas safety inspections by Gas Safe registered engineers across Marble Arch, Marylebone, Bayswater, Paddington and surrounding W1, W1H and W2 postcodes. Signed service records and certificates issued same day.
We carry out annual boiler services and landlord CP12 gas safety inspections across the Marble Arch, Marylebone and Bayswater area — a part of London we know well, with its own specific property types and heating system characteristics. The large Georgian townhouses of Marylebone streets such as Gloucester Place and Portman Square often have multi-zone heating systems, sometimes with older boiler configurations in basement plant rooms or on upper floor landing cupboards. The mansion blocks of Bayswater and Connaught Square have individual apartment heating systems alongside communal services.
This is also one of London's most active landlord markets. The short-term rental, corporate let and managed property sectors are all significant in W1H and W2, and gas safety compliance — particularly annual CP12 certification — is a non-negotiable requirement. We work with landlords, managing agents, block management companies and corporate property managers across the area to deliver efficient, properly documented annual gas safety programmes.



Whether your boiler is in a Marylebone townhouse or a Bayswater mansion flat, the same manufacturer requirements apply. Vaillant, Viessmann, Worcester Bosch and Ideal all require annual servicing by a Gas Safe registered engineer to keep extended warranties valid. We issue a signed service record on every visit and will remind you when the next annual is due — at no charge.
Multi-zone heating systems, often with system boilers and separate cylinders. Boiler access can be challenging in older Marylebone properties — we arrive prepared.
Individual apartment heating systems within larger managed buildings. We work with block managers and understand building access requirements common across Bayswater.
Victorian terraces converted to flats throughout Paddington and the Edgware Road area. Shared flues and varied system configurations are common — our engineers know what to expect.
High-spec combi and system boilers in more recent developments across the area — particularly around Paddington Basin. We service all major brands to manufacturer specification.
The Marble Arch, Marylebone and Bayswater area has a very high density of managed residential properties, corporate lets and short-term rental units. We understand the compliance requirements that come with this — particularly around annual CP12 certification, which must be renewed for every rental unit every 12 months regardless of tenancy arrangements. We work with managing agents and block management companies across W1, W1H and W2 on annual compliance programmes — coordinating access, dealing with tenants and building concierge arrangements, and providing digital certificates and renewal tracking for each property.
Tell us the property postcode, boiler make and your preferred dates. We'll confirm availability and any building access arrangements needed.
We give a two-hour arrival window and keep to it. For managed buildings we'll liaise with concierge or porter arrangements as needed.
Full manufacturer-specific service carried out, and if required, the full CP12 gas safety inspection on all gas appliances at the property.
Service record and CP12 issued digitally the same day — to landlord, agent and tenant as required. We'll set up annual renewal reminders for every property on our books.
